Abnormal Psychology is the systematic study of abnormal behaviour it is a branch of psychology that is concerned with the etiology, symptomatology and the process of mental illnesses. After defining abnormality we will discuss the challenges involved in characterising abnormal behaviour as well as the causes of abnormality. Following this we will discuss the Diagnostic and Statistical Manual of Metal Disorders and related topics. The concept of psychological assessment, behavioural assessment, multicultural assessment, environmental assessment and physiological assessment would be discussed with relevant examples. Raju, 26 year old, was laughing when he was brought to the ward by the nurse looked like he was having a good time. Before the nurse could introduce him to the staff, he said, Cricket, I love cricket! I have never played cricket in my life but that is what I am going to do while I am here. He then went on to talk about his mother and then suddenly described what he had for dinner the previous night. Few days back, Raju had spent all his money and that of his elderly parents and bought an expensive professional camera. Without any formal training in photography, he thought he could set up the best studio in the city and make lot of money. How would you feel if you were to see someone like Raju walking in your neighborhood Anything that deviates from the normal or differs from the usual or typical is called abnormal. However there can be exceptions and certain very unusual behaviours may also be considered normal in the given cultural/social context. Thus, there are certain criteria that help us define abnormality and also distinguish between what is normal and abnormal. Impairment: According to this criterion, maladaptive behaviours that prevent an individual from functioning in daily life can be considered abnormal. For example, when a woman consumes psychoactive substances (drugs), her cognitive and perceptual abilities are impaired and she would be at risk if she drives in this state. In certain situations, the person may report feeling great and describe oneself in positive terms but those around may suggest that s/he is functioning inadequately in her/his personal or work life. In the case mentioned earlier, Raju spent all his savings to set up a studio due to impaired judgement. Distress: this criterion suggests that behaviours should be considered abnormal if the individual suffers discomfort as a result of the behaviours and wish to get rid of them. For example, a victim of an extremely traumatic event may experience unrelenting pain or emotional turmoil and may not be able to cope in daily life. A severely depressed individual is at risk for committing suicide and therefore the condition is referred to as abnormal. Similarly, a person suffering from Schizophrenia is out of touch with reality and may put oneself and/ or others at risk. Certain behaviours may be acceptable in some cultures but considered odd in certain others. Thus, the social context needs to be taken into account while judging behaviour as normal or abnormal. In 1973, David Rosenhan conducted a classic study that threw light on the difficulties involved in this process 8 sane individuals were able to trick the staff of 12 psychiatric hospitals across the United States. Each of them was gainfully employed and presented oneself at these hospital reporting hearing voices such as Empty, Hollow, and Thud. Except their names and employment, none of their other details were changed and thus their history and present behaviour (except for the symptoms) could not be considered abnormal in any way. Interestingly, all the hospitals admitted these pseudopatients and although they stopped producing the symptoms immediately following the admission, none of the staff members noticed it. On the contrary, their ordinary actions were taken as additional evidence of their abnormality. What was most striking was the inhuman approach of the staff the pseudopatients felt as if nobody from the staff was concerned about their needs. Since this study involved deception of the mental health professionals, it was criticised for ethical reasons. Questions pertaining to why a control group was not used for comparison were raised. It was also said that since the 5 symptoms reported (hallucinations) were of a serious nature, most clinicians would have done what the hospital staff did. He reported 7 cases with documented history of chronic Schizophrenia, 6 of which were not treated even while they were in the active phase of symptoms. She was denied admission everywhere and at the most, diagnosed with depression with psychotic symptoms, prescribed some medication and sent away. There are certain assumptions about the causes of abnormality if one considers the biological approach, one might think that the abnormal behaviours are caused by a biological factor such as genetic vulnerability to a disorder, inherited from a parent. If one takes the psychological approach, one might assume that the early childhood experiences or the self concept are responsible for the symptoms. Looking at it from the social perspective, one might think that the symptoms stem from the interpersonal relationships or the social environment in which an individual lives. What is often asked is whether the cause is biological or psychological or social

Many individuals with bulimia nervosa employ several methods to compensate for binge eating infection jobs discount keftab 500mg visa. In some cases, vomiting becomes a goal in itself, and the individual will binge eat in order to vomit or will vomit after eating a small amount of food. Individuals generally become adept at inducing vomiting and are eventually able to vomit at will. Individuals with diabetes mellitus and bulimia nervosa may omit or reduce insulin doses in order to reduce the metabolism of food consumed during eating binges. Individuals with bulimia nervosa may fast for a day or more or exercise excessively in an attempt to prevent weight gain. Individuals with bulimia nervosa place an excessive emphasis on body shape or weight in their self-evaluation, and these factors are typically extremely important in determining self-esteem (Criterion D). Individuals with this disorder may closely resemble those w^ith anorexia nervosa in their fear of gaining weight, in their desire to lose weight, and in the level of dissatisfaction with their bodies. Rare but potentially fatal complications include esophageal tears, gastric rupture, and cardiac arrhythmias. Individuals who chronically abuse laxatives may become dependent on their use to stimulate bowel movements. Gastrointestinal symptoms are commonly associated with bulimia nervosa, and rectal prolapse has also been reported among individuals with this disorder. Prevalence Twelve-month prevalence of bulimia nervosa among young females is 1%-1. Point prevalence is highest among young adults since the disorder peaks in older adolescence and young adulthood. Development and Course Bulimia nervosa commonly begins in adolescence or young adulthood. The binge eating frequently begins during or after an episode of dieting to lose weight. Disturbed eating behavior persists for at least several years in a high percentage of clinic samples. The course may be chronic or intermittent, with periods of remission alternating with recurrences of binge eating. However, over longer-term follow-up, the symptoms of many individuals appear to diminish with or without treatment, although treatment clearly impacts outcome. Periods of remission longer than 1 year are associated with better long-term outcome. Significantly elevated risk for mortality (all-cause and suicide) has been reported for individuals with bulimia nervosa. Individuals who do experience cross-over to anorexia nervosa commonly will revert back to bulimia nervosa or have multiple occurrences of cross-overs between these disorders. A subset of individuals with bulimia nervosa continue to binge eat but no longer engage in inappropriate compensatory behaviors, and therefore their symptoms meet criteria for binge-eating disorder or other specified eating disorder. Internalization of a thin body ideal has been found to increase risk for developing weight concerns, which in turn increase risk for the development of bulimia nervosa. Individuals who experienced childhood sexual or physical abuse are at increased risk for developing bulimia nervosa. Childhood obesity and early pubertal maturation increase risk for bulimia nervosa. Familial transmission of bulimia nervosa may be present, as well as genetic vulnerabilities for the disorder. Severity of psychiatric comorbidity predicts worse long-term outcome of bulimia nervosa. In clinical studies of bulimia nervosa in the United States, individuals presenting with this disorder are primarily white. G ender-Related Diagnostic issues Bulimia nervosa is far more common in females than in males. These include fluid and electrolyte abnormalities, such as hypokalemia (which can provoke cardiac arrhythmias), hypochloremia, and hyponatremia. The loss of gastric acid through vomiting may produce a metabolic alkalosis (elevated serum bicarbonate), and the frequent induction of diarrhea or dehydration through laxative and diuretic abuse can cause metabolic acidosis. In some individuals, the salivary glands, particularly the parotid glands, may become notably enlarged. Serious cardiac and skeletal myopathies have been reported among individuals following repeated use of syrup of ipecac to induce vomiting. Comprehensive evaluation of individuals with this disorder should include assessment of suicide-related ideation and behaviors as well as other risk factors for suicide, including a history of suicide attempts. Functional Consequences of Buiimia Nervosa Individuals with bulimia nervosa may exhibit a range of functional limitations associated with the disorder. For individuals with an initial diagnosis of anorexia nervosa who binge and purge but whose presentation no longer meets the full criteria for anorexia nervosa, binge-eating/purging type.

It is therefore important to distinguish among these disorders based on differences in their characteristic features antibiotic resistance fact sheet discount keftab. Borderline personality disorder can further be distinguished from dependent personality disorder by a typical pattern of unstable and intense relationships. Dependent personality disorder must also be distinguished from symptoms that may develop in association with persistent substance use. Is preoccupied with details, rules, lists, order, organization, or schedules to the extent that the major point of the activity is lost. Is excessively devoted to work and productivity to the exclusion of leisure activities and friendships (not accounted for by obvious economic necessity). Is overconscientious, scrupulous, and inflexible about matters of morality, ethics, or values (not accounted for by cultural or religious identification). Is unable to discard worn-out or worthless objects even when they have no sentimental value. Is reluctant to delegate tasks or to work with others unless they submit to exactly his or her way of doing things. Adopts a miserly spending style toward both self and others; money is viewed as something to be hoarded for future catastrophes. Diagnostic Features the essential feature of obsessive-compulsive personality disorder is a preoccupation with orderliness, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency. Individuals with obsessive-compulsive personality disorder attempt to maintain a sense of control through painstaking attention to rules, trivial details, procedures, lists, schedules, or form to the extent that the major point of the activity is lost (Criterion 1). They are excessively careful and prone to repetition, paying extraordinary attention to detail and repeatedly checking for possible mistakes. They are oblivious to the fact that other people tend to become very annoyed at the delays and inconveniences that result from this behavior. For example, when such individuals misplace a list of things to be done, they will spend an inordinate amount of time looking for the list rather than spending a few moments re-creating it from memory and proceeding to accomplish the tasks. Time is poorly allocated, and the most important tasks are left to the last moment. They may become so involved in making every detail of a project absolutely perfect that the project is never finished (Criterion 2). For example, the completion of a written report is delayed by numerous time-consuming rewrites that all come up short of "perfection. Individuals with obsessive-compulsive personality disorder display excessive devotion to work and productivity to the exclusion of leisure activities and friendships (Criterion 3). They often feel that they do not have time to take an evening or a weekend day off to go on an outing or to just relax. They may keep postponing a pleasurable activity, such as a vacation, so that it may never occur. Hobbies or recreational activities are approached as serious tasks requiring careful organization and hard work to master. They may force themselves and others to follow rigid moral principles and very strict standards of performance. Individuals with this disorder are rigidly deferential to authority and rules and insist on quite literal compliance, with no rule bending for extenuating circumstances. Individuals with this disorder may be unable to discard worn-out or worthless objects, even when they have no sentimental value (Criterion 5). Their spouses or roommates may complain about the amount of space taken up by old parts, magazines, broken appliances, and so on. Individuals with obsessive-compulsive personality disorder are reluctant to delegate tasks or to work with others (Criterion 6). They stubbornly and unreasonably insist that everything be done their way and that people conform to their way of doing things. At other times they may reject offers of help even when behind schedule because they believe no one else can do it right. Individuals with this disorder may be miserly and stingy and maintain a standard of living far below what they can afford, believing that spending must be tightly controlled to provide for future catastrophes (Criterion 7). Obsessive-compulsive personality disorder is characterized by rigidity and stubbornness (Criterion 8). These individuals plan ahead in meticulous detail and are unwilling to consider changes. Totally wrapped up in their own perspective, they have difficulty acknowledging the viewpoints of others. C3n other occasions, anger may be expressed with righteous indignation over a seemingly minor matter. Individuals with this disorder may be especially attentive to their relative status in dominance-submission relationships and may display excessive deference to an authority they respect and excessive resistance to authority they do not respect. Their everyday relationships have a formal and serious quality, and they may be stiff in situations in which others would smile and be happy. They carefully hold themselves back until they are sure that whatever they say will be perfect. Individuals with this disorder may experience occupational difficulties and distress, particularly when confronted with new situations that demand flexibility and compromise. Many of the features of obsessive-compulsive personality disorder overlap with "type A" personality characteristics.

The role of the media in the perpetuation of social perceptions and stigma of Tourette Syndrome Stories that appear in the media are often dramatised in order for them to appear more appealing to the public and this is the case for many stories about Tourette Syndrome antimicrobial effects of spices cheap keftab 125mg line. This has been both a positive and a negative for people who live with Tourette Syndrome as it has created a platform for raising awareness and provided a way to connect with others who live with the disorder, however it has also allowed for the stigma to be spread in an immense manner. For many people, these videos are their first introduction to Tourette Syndrome, therefore instilling false perceptions and immediately creating a sense of ignorance towards the disorder. These videos can impact on the people who live with Tourette Syndrome, with one person I surveyed answering 17 YouTube. These forms of modern day communication are available to society any where and any time and not only assist in the spread of misleading YouTube videos, but also introduces other ways in which to create false perceptions of the disorder. Upon analysis of many of the memes created about Tourette Syndrome, I determined that the most common themes represented were cursing, loud vocal outbursts and people with the disorder just saying whatever is on their mind. Most of the memes were designed to be humorous, but were actually derogatory towards people who have the condition. Adam Ladell, a sixteen year old known for attaining second place on the Voice Australia 2016 (Nine Network), started his YouTube channel TicTwitchTeen in 2014 to speak to and help others who, like him, have Tourette Syndrome. A video Ladell posted of himself singing went viral, gaining over fifteen 18 million views. The effect of the consequences of these ill-conceived societal perceptions on crucial moments in the life of people with Tourette Syndrome, such as coming of age rituals, the socialisation process, forming relationships and seeking employment, was evident in primary findings. Socialisation is a lifelong process of learning in which the individual learns to deal with the social world by gaining knowledge and understanding of the rules and expectations for the social situations they may find themselves in. For youth with Tourette Syndrome, the influences of secondary socialisation typically consist of the people who carry the most misconceptions about their disorder. The social group sets out norms to help the youth master uncertainty, including what clothes to wear, what music to listen to and what language to use. Their answers were then compared to youth who had Attention Deficit 19 Tari Topolski PhD, 2015, Quality of life among youth with Tourette Syndrome. In all areas, those with Tourette Syndrome reported the lowest quality of life scores. Results showed that youth who had more severe tics or had Obsessive Compulsive Disorder or Attention Hyperactivity Disorder as comorbid conditions reported feeling more unwelcome, spent less time with friends and had more family arguments than youth who had milder tics and no comorbid conditions. The most common themes mentioned were about the difficulties youth faced in school due to the ridicule they received because of their tics or their tics interfering with their ability to complete exams. A number of the participants felt a need to protect themselves and they believed the only solution was to socially isolate themselves from their peers. The main message taken from this study was that the stigmatisation of Tourette Syndrome is hurtful and has an impact on both the quality of life and the socialisation process of those who live with the condition. The paper made reference to a 1998 survey of individuals with Tourette Syndrome about their educational experiences which revealed that sixty eight per cent had difficulties getting along with classmates and seventy per cent of children with Tourette Syndrome were teased by their peers because of their tics. This led the professors conducting the 2007 study to conclude that children with Tourette Syndrome appear to have an increased risk of social rejection and isolation. In my own experience, I was not diagnosed with Tourette Syndrome until the age of sixteen and was part of a small, supportive year group at a rural school, so my disorder never caused me to become a subject of bullying or discrimination, however I found it difficult to come to terms with my diagnoses. Telling people I had Tourette Syndrome was difficult as I did not want to be perceived as different from everybody else. Socialising with other adolescent females became challenging, as whilst they were expressing their desires for straighter hair or flatter stomachs all I wished for was to stop making strange noises and the ability to control my body. Confidence was a major predicament for these adolescents, who came from both rural and urban environments, with responses such as finding their disorder embarrassing, problems assimilating with their peer group and unwillingness to socialise due to tics. A large amount of these students were victims of bullying, which effected their confidence and sense of identity. In some cases, this unfair treatment led to mental health issues such as depression and anxiety, which further complicated their efforts to create a sense of belonging within their peer group. An adult respondent said that during high school she developed social anxiety as a result of trying to 21 supress her tics so they would be less noticeable to others. In an interview with Tommy, a thirteen-year-old boy with Tourette Syndrome, he said that the stress of not being able to fit in and finding it hard to focus had impacted upon his schooling. Impact of social perceptions and stigma on adult life In a large number of cases, tics tend to cease around the age of twenty five as the brain becomes fully developed so many people who suffered Tourette Syndrome as a child are able 22 to live a tic-free adult life. However, this is not always the case and there are many adults who still live with the disorder and its comorbid conditions. For some of these adults the many damaging societal perceptions and stigma of their disorder stays with them throughout their lives, impacting on important life features such as employment, relationships and personal wellbeing. The documentary showed a broad range of cases, most of whom found it hard to make friends and interact within the macro world, as well as trouble seeking employment. One of the people in the documentary is Brad 21 th Interview with Tommy (name used with permission), conducted 14 July 2016 22 Interview with Robyn Latimer, president of the Tourette Syndrome Association of Australia, conducted on the th 18 March 2016 22 Cohen, an American teacher, who was rejected by twenty four schools because of his loud 23 vocal tics before one gave him a chance. Five Australian survey respondents over the age of eighteen said that their condition had impacted on their career prospects. Four said that they had either not been selected for or made redundant from a job due to their Tourette Syndrome. The stigma that has been created from the varying misconceptions can also be a burden when beginning a relationship.

To avoid this antimicrobial mold cleaner discount keftab 375mg visa, test vibration sense, then proprioception, then pinprick and temperature. Generally it is worse to find something that is not there than to miss something that is. Remember, it is perfectly reasonable to be asked to examine a patient with no neurological abnormalities. If, for example, you found that sensory testing was not adequate because of time, say so. Stage 2: Describe your findings, coming to some sort of conclusion the examiners will have watched you examine the patient and will have a reasonable idea of what you have found (demonstrated). This is long-winded, but allows you to describe the physical signs and your reasoning. The tone in the right leg was increased, with spasticity at the knee and clonus at the right ankle. There was pyramidal weakness in the right leg, hip flexion grade 2, hip extension grade 2, knee extension grade 3, flexion grade 2, foot dorsiflexion grade 1 and plantar flexion grade 3. The tendon reflexes in the right leg were pathologi cally brisk with an extensor right plantar; the left-sided reflexes were normal with a flexor plantar. There was loss of vibration sense in the right leg to the anterior superior iliac spine, loss of joint position sense in the toes, and re duced proprioception at the knee. Pinprick and temperature were lost in the left leg to a sensory level at the costal margin. Coordination was not tested on the right be cause of weakness; on the left it appeared normal. External compression most commonly occurs from disc disease, spondylosis or tumours,* most commonly bony secondar ies, though also meningiomas or neurofibromas. Intrinsic lesions are most commonly due to demyelination, either myelitis or related to multiple sclerosis;* more rarely, vas cular lesions such as cord infarcts can produce this problem (though typically they produce anterior cord syndromes) or very rarely intrinsic spinal cord tumours. There is moderate right-sided brady kinesia, evident on fast repeating movements of hand and foot. This is more succinct and gives the opportunity to discuss and clarify signs before coming to a synthesis. If these are not quite right, the examiner may wish to prompt you towards the correct interpretation. However, if signs or synthesis are incorrect, it is more difficult for the examiner to prompt with questions. Approach 2 is probably the correct strategy in postgraduate examina tions if no specific question is asked. If no one else is there, do it anyway, to practise putting your thoughts into words. You can classify potential causes according to their pathological process rather than specific diseases. Start with common causes; if you suggest a rare cause you might want to tell the examiners you appreciate that it is rare. The examiners are interested in your clinical reasoning, so part of the test is to see how you approach the differential diagnosis. Euphemisms: If the discussion occurs while the patient is there, you will be expected to use euphemisms for diagnoses you dis cuss that are potentially alarming for the patient (especially if they have something else). Examples include: demyelination for multiple sclerosis; anterior horn cell disease for amyotrophic lateral sclerosis (motor neurone disease); neoplasia for cancer. Avoid this by starting with an anatomical or syndromic diagnosis and then suggest pathologies, starting with common diseases and then moving on to rarer problems. Sometimes (well, quite often) people get so flus tered in exams that they do not do as well as they should. You can avoid this by practising both neurological examination and being in a stressful situation. Presenting cases at clinical meet ings or simply asking questions in meetings or lectures pro vides useful practice in articulating your thoughts under stress. If you have not seen a patient with a particular disease, then turn the textbook descriptions into descriptions of imaginary patients with appropriate physical signs. This not only helps you remember and recognise the conditions but also helps you practise putting it into words. You can do this anywhere, in the bath or on the bus (though best not say it out loud then! If you have only had a limited history and been able to do a partial neurological examination, you would normally take a full history and complete examination. Suggest this, but indicate what particular aspects you would focus on; for example, in a patient with a neuropathy you might suggest that you would be interested in general medical his tory, drug or toxin exposure, alcohol intake and detailed family history. However, if there is a specific complicated test that would solve the problem, that is the one to do. I would first review the history, in particular the speed of onset of his current problems, and seek evidence of previous neurological episodes or other significant medical problems, particularly any history of malignancy. A full examination might provide other clues, either of general medical problems or evidence of other neurological lesions. Simple investigations such as blood count, looking for anaemia, prostate-specific antigen or liver function tests and chest X-ray, as directed by the history, may be helpful, but the crucial investigation is spinal imaging to determine the nature and level of the spinal lesion. This is going to determine the further investigation and management and needs to be done urgently. The longer-term management will depend on the cause of his spinal cord syndrome and the potential scope for recovery. Rehabilitation, including physiotherapy and oc cupational therapy, will be important to minimise his disability. In a younger patient, demyelination or benign tumours would be more likely; in an older patient, malignancy or degen erative changes would be more likely. I would first review the history, to determine the onset of the problem, any possible associated problem (for example, uri nary symptoms, symptoms of postural hypotension or memory problems) and to find out how the patient is affected in every day activities, as this will guide management. If this patient is right-handed, it is likely that he would need to go on to the next stage, when either a dopamine agonist, such as ropinirole or pramipexole, or L-dopa, in combination with a dopa decarboxylase inhibi tor, can be added, titrating the dose according to symptomatic benefit (symptom management). The patient needs to understand his illness to participate in the decisions over management and thus needs to be given appropriate informa tion. Physiotherapy and occupational therapy are helpful in maintaining function and independence. Surgery can be used later in the disease in some patients (general management includ ing long-term strategy). Many students and junior doctors become anxious as they approach exams; however, they are usually a good deal more proficient than they think they are. Most can make great strides with only a little help, usually in organising their thoughts. If students get themselves into this pre dicament, it is often through a reluctance to practise something they feel incompetent doing.

There is no test, battery of tests, or set of procedures that invariably distinguishes dissociative amnesia from feigned amnesia. Individuals with factitious disorder or malingering have been noted to continue their deception even during hypnotic or barbiturate-facilitated interviews. During the depersonalization or derealization experiences, reality testing remains intact. The disturbance is not attributable to the physiological effects of a substance. He or she may also feel subjectively detached from aspects of the self, including feelings. The unitary symptom of "depersonalization" consists of several symptom factors: anomalous body experiences. Auditory distortions can also occur, whereby voices or sounds are muted or heightened. Individuals with the disorder have been found to have physiological hyporeactivity to emotional stimuli. Prevalence Transient depersonalization/derealization symptoms lasting hours to days are common in the general population. In general, approximately one-half of all adults have experienced at least one lifetime episode of depersonalization/derealization. Deveiopment and Course the mean age at onset of depersonalization/derealization disorder is 16 years, although the disorder can start in early or middle childhood; a minority cannot recall ever not having had the symptoms. Less than 20% of individuals experience onset after age 20 years and only 5% after age 25 years. Duration of depersonalization/derealization disorder episodes can vary greatly, from brief (hours or days) to prolonged (weeks, months, or years). About one-third of cases involve discrete episodes; another third, continuous symptoms from the start; and still another third, an initially episodic course that eventually becomes continuous. Internal and external factors that affect symptom intensity vary between individuals, yet some typical patterns are reported. Overconnection schemata involve impaired autonomy with themes of dependency, vulnerability, and incompetence. In particular, emotional abuse and emotional neglect have been most strongly and consistently associated with the disorder. Marijuana use may precipitate new-onset panic attacks and depersonalization/derealization symptoms simultaneously. However, there are individuals who initially induce these states intentionally but over time lose control over them and may develop a fear and aversion for related practices. The affectively flattened and robotic demeanor that these individuals often demonstrate may appear incongruent with the extreme emotional pain reported by those with the disorder. Feelings of numbness, deadness, apathy, and being in a dream are not uncommon in major depressive episodes.

In a way best antibiotic for uti least side effects generic 750mg keftab visa, the concept of distributed control is a compromise between the two approaches, because it implies cortical specialisation (localisation of function) but also suggests that several (perhaps many) interconnected but anatomically distrib uted centres may be involved in the overall process. In reality, such processes are complex and multi-tiered, involving the collaborative e orts of many underlying mechanisms. For some neuropsychologists, Jerry Fodor captured the essence of this emerging view in his in uential book the modularity of mind (1983). He argued that it was necessary to distinguish between two classes of cognitive processes: central systems and modules. The former are non-speci c in the sense of operating across cognitive domains: attention, thinking, and memory have been suggested as examples. Modules, on the other hand, are domain speci c in that they only process very particular types of input information: colour, shape, movement, faces, and so on. As for the distinction between localised modules and non-localised higher order cognition, here we must tread very carefully. Certainly there is good evidence for modularity within perceptual systems: Zeki et al. Thus it could be argued that even processes such as atten Parallel information tion and memory, though not localisable to singular speci c locations (modules), processing: the idea that the brain processes two are nevertheless localisable to networks (or is this a contradiction in terms You actually have both a right and a left precuneus (one in the right hemisphere and another in the left). The precuneus has reciprocal cortical connections (inputs to and outputs from) with other parietal regions: parts of the frontal and temporal lobes and the anterior cingulate gyrus. It has reciprocal subcortical connections with the thalamus, and sends outputs to the striatum and several brainstem areas. Functional investigations have identi ed at least four roles for this hitherto poorly understood region. Second, the precuneus has been strongly implicated (along with the prefrontal and anterior cingulate regions) in imagery components of episodic memory retrieval (memory for previously experienced events sequenced in time, in which, presumably, one might use imagery to run through the sequence of events to be recalled) and was labelled by Fletcher et al. Closer investigation has indicated that the anterior part may be particularly involved in imagery, while the posterior region is associated with successful retrieval in general. This network also includes other medial and lateral parietal regions, and a lateral frontal region known as the insula. The Brodmann area: A region of the cortex de ned on the opposite side of this coin is that it becomes markedly inactive during altered basis of cytoarchitecture. This Thalamus: A multi preliminary evidence has been marshalled to suggest that the precuneus may be functional subcortical brain region. In certain respects, however, the cognitive neuro psychology approach and methodology is quite distinct from that of clinical neuropsychology (as exempli ed by Geschwind). It is hidden in the posterior part of the longitudinal ssure [after Critchley, M. Typical of the cognitive neuropsychological approach, the model describes the component processes (and their connections) assumed to underpin normal and faulty object recognition. According to Coltheart (2001), cognitive neuropsychology attempts to interpret cognitive disorders in terms of selective impairments of functional architectures. According to Coltheart if they were not, cognitive-neuropsychological research would have run into severe di culties by now, whereas in fact the approach continues to be very informative. So, as with any other hypotheses, the scientist retains them until the evidence dictates that they should be rejected (Popper, 1934). However, careful examination of his cognitive impairments revealed an additional speci c problem with his knowledge of objects, suggesting a profound semantic impairment. In other words, he certainly retained considerable semantic information about animals despite not knowing how many legs they had. From a cognitive neuropsychological perspective, the implication of these ndings is that there must be separate independent systems of knowledge about the properties of objects and their visual appearances. Of course there may, in fact, be separate systems of perceptual knowledge (about objects) for each of our senses, in addition to a system for non-perceptual object knowledge. Small N research makes for problems of generalisability in any discipline, and neuropsychology cannot be excepted. As for the inclination to marginalise, or even ignore, matters of brain neuroanatomy, it should be noted that the continuing development of in-vivo techniques (see Chapter 2) means that data about functional activation in the brains of people both with and without damage as they undertake various psychological challenges are now readily accessible, and this is likely to mean that cognitive neuropsychologists will, in the future, have to take more notice of the brain. A concise account of the key events in the history and development of neuropsychology is offered by Selnes (2001). In the intervening years, researchers have debated the extent to which the brain operates on the basis of localisation of function or according to the principles of equipotentiality and mass-action. Although still a matter of considerable debate, most modern-day researchers favour some form of localisation, albeit one involving specialised distributed networks, as providing the best account for our understanding of how the brain actually operates. Equipotentiality and mass-action currently have few advocates among brain scientists. In this chapter we have traced the development of scienti c brain research, and introduced some of the theories that have surfaced as our understanding of these relationships has developed. A promising start in the 19th century gave way to a period in the rst half of the 20th when psychology was dominated by theories and ideas that made only passing reference to the brain. Renewed interest in physiological psychology in the second half of the 20th century, along with greater interest in cognitive processes within psychology, set the scene for the birth (rebirth Although it is not an entirely uni ed enterprise, its cognitive and clinical strands complement one another in many respects. The rapid increase in access to , and consequent use of, in vivo imaging procedures (which brings into the equation both clinical and non-brain damaged cases) is likely to lead to greater convergence. These techniques also provide exciting new insights into the functions of particular cortical regions, and the precuneus is an excellent example of this. The advent of in-vivo neuroimaging tech niques over the last 20 years has revolutionised neuropsychology, providing research opportunities that were previously unthinkable. In-vivo imaging has, for example, con rmed some of the long-suspected roles of particular brain regions in certain psychological processes.
