Many researchers and clinicians are diagnosing depressed children according to criteria resembling those used to diagnose depressed adults. To investigate cognitive correlates of depression in children two studies were conducted. In the first study 37 children in grades 5-7 were given a booklet containing the Children's Depression Inventory (CDI)…

A study of 21 patients with Alzheimer's Disease and 25 with vascular dementia, the two most common forms of dementia, investigated language impairments in the dementia syndrome to see if analysis of language disturbances is helpful in differential diagnosis. Diagnostic assessment included a neurological examination, detailed medical history,…

While there have been few reports of psychological assessment of eating disordered patients, studies using the Minnesota Multiphasic Personality Inventory (MMPI) to assess eating disordered subjects found that female anorexics had remarkably similiar profiles (score elevations of 70 or more) to female schizophrenics on the Depression (D),…

Most patients with diagnosable major depression may fail to show the classic symptom pattern for which standard assessment instruments were designed. To investigate the influence of subtype of depressive illness on Zung Self-Rating Scale (SDS) and Hamilton Rating Scale (HRS) validity, 36 in-patients, who met Diagnostic and Statistical Manual…

The relationship between cognitive psychologists and researchers in artificial intelligence carries substantial benefits for both. An ongoing investigation in causal reasoning in medical problem solving systems illustrates this interaction. This paper traces a dialectic of sorts in which three different types of causal resaoning for medical…

The high incidence of reported posttraumatic stress disorder (PTSD) among Vietnam veterans has prompted researchers to search for reliable assessment and treatment procedures for this disorder. Although some encouraging preliminary data on the use of the Minnesota Multiphasic Personality Inventory (MMPI) have been obtained, it is uncertain if this…

The clinical inference process in test interpretation is described so that people can more easily communicate about it, teach it, and learn it. Chapter 1 compares different levels (concrete, mechanical, and individualized) of interpretation of the same test. Chapter 2 offers examples of an often-neglected kind of data necessary for individualized…

This study attempted to clarify the kind of correlations that can be found in the speech behavior of high-risk children in comparison with children without neonatal risk complications. The study concentrated on the articulatory ability of 430 five-year-old children with neonatal risk complications; it applied a cross-disciplinary diagnosis (child…

An exploratory study of structured and unstructured play was conducted with a small number of severely disturbed and normal children 9 to 13 years of age. Specifically, the investigators characterized psychopathology from a cognitive-developmental perspective by focusing on the Piagetian "scheme" and its manifestation in the play and…

The study examined pre-, peri-, and neonatal factors in 271 British infants (weighing less than 1500 grams at birth), 188 of whom survived to 2 years. The study represented an attempt to define those factors which predict normal neurodevelopmental outcome in very low birth weight (VLBW) infants. Surviving infants were seen at 3, 6, 9, 12, and 24…

A study examined the application and availability of clinical and biomedical knowledge in the clinical reasoning of physicians as well as possible mechanisms responsible for changes in the organization of clinical and biomedical knowledge in the development from novice to expert. Subjects were 28 students (10 second year, 8 fourth year, and 10…

The paper presents the thesis that experienced physicians, while diagnosing routine cases, are operating upon knowledge structures that are distinctively different from those of novice physicians and students. In the course of their medical training, students develop rich, elaborated causal networks, explaining the causes and consequences of…

Until recently it has been possible only to measure the behavioral products of cognitive processing, e.g. reaction time. However, this is a rather indirect way of studying brain substrates of cognition. Psychophysiological techniques can be used to study the neural mechanisms of cognition. In this experiment brain electrical activity was measured…

The use of a traditional syndrome-classification system for aphasics is examined critically from the different perspectives of medicine and psychometrics. Medicine views syndromes as dichotomous (present or not present) and necessarily indicative of an underlying pathognomic state or process, and psychometrics sees performances as varying along a…

In two studies, the role of biomedical knowledge in the diagnosis of clinical cases by physicians and medical students was explored. Experiment 1 demonstrated a decrease in the use of biomedical knowledge with increasing expertise. This result appeared to be at variance with some findings reported in some but not all of the literature. In…
