Psychological assessment of catatonic schizophrenia

Probably due to the rarity of the disorder and the general inability of catatonic patients to cooperate with standardized assessment, no data exist documenting the psychological features associated with catatonic schizophrenia that may appear on psychological tests. This study utilized standard assessment techniques to examine clinical hypotheses regarding the psychogenic correlates of catatonic conditions from the performance of one man on psychological tests. In accordance with previous theory, test findings indicated frequent constriction, rigidity, and negativism in conjunction with compulsive traits. Experiences of cognitive and self-fragmentation were juxtaposed with a formal, mechanistic body ego; disorganization and discontinuity were countered with attempts at self-cohesion. Depressed feelings and human interest were apparent, although interpersonal relatedness was frequently characterized by an avoidant, distancing style.     

Clinical multiplicity of cerebrovascular disorders in childhood

A group of 107 children with vascular diseases of the nervous system aged 3-14 years have been studied. In 100 children of the study group acute disturbances of the brain blood circulation have been found, out of which 37 children were with transitory ischemic attacks; 29 were found to be with brain ischaemia; 22-with haemorrhages (7 cases with subarchnoidal, 9 cases with intracerebral and 6 cases with subarachnoidal-parenchimatose); 5 children had wenous thromboses; 7 children were with spinal strokes. In other 7 children we found the presence of Sturge-Weber syndrome. Congenital vascular malformations have been found in 32 children (30%), out of which 16 children (15%) with loops and stenosis of the extracranial segments of the internal carotid artery, and another 16 children (15%) with AV-malformations. Congenital and acquired heart diseases are found to be primary cause for the strokes in 12 children (11%). Considerable is the rate of the epileptic seizures in the acute stage of the strokes as well as of the residual epileptic syndromes.     

Information search following damage to the frontal lobes

Five adult patients with focal brain damage in different areas of the frontal lobes and five matched controls were administered a 20 Questions test. Other tests of planning, problem-solving, and decision-making were also administered to frontal lobe patients. The results indicate that damage to the frontal lobe impairs the ability to impose and utilize hierarchical organization in mental representation.     

The expected likelihood of transitivity of preference

May's model of pairwise preference determination is used to assess the expected likelihood that a subject's pairwise preference comparisons on three alternatives will be transitive. A closed form representation for this expected likelihood is obtained for each situation considered. When the subject is assumed to act precisely according to rankings on attributes with May's model, the computed expected likelihoods the relatively large. When the subject becomes a probabilistic chooser, as defined in a specific manner, expected likelihoods of transitivity decrease significantly from corresponding values with May's model. For a probabilistic Chooser, there is a significant likelihood that the subject might yield transitive pairwise preferences substantially different than the results suggested by May's model.This research was supported by a grant from the General University Research Program and through a fellowship from the Center for Advanced Study, both of the University of Delaware. Very helpful input from John H. Antil, Meryl P. Gardner, and James M. Munch is also acknowledged.     

Grading the ‘cultural literacy’ project

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.     

Changes in information as a function of a culturally appropriate smoking cessation community intervention for Hispanics

Tested a 7-month, media-based, community intervention among Hispanics in San Francisco designed to change levels of information on the damaging effects of cigarette smoking and on the availability of culturally appropriate cessation services. Three community-wide surveys of Hispanics were conducted with independent random samples, two as baselines (n = 1,660 and 2,053) and one postintervention (n = 1,965). Results showed that changes in the level of awareness of cessation services had taken place after implementation of the intervention. Furthermore, those changes took place primarily among the less acculturated Spanish-speaking Hispanics who were the target of the intervention. The changes in information reported here demonstrate that a culturally appropriate information dissemination campaign that utilizes multiple channels can produce changes in a community's level of information even when the campaign is implemented for a relatively short period.     

Changing contexts and the field of community psychology

Conclusion The legacy of the Swampscott conference 25 years ago is palpable. The scientific accomplishments have been substantial. The four agendas I have presented for the future development of the field depend upon psychologists as individuals and psychologists as participants in our departments, colleges, universities, professional societies, and peer review panels to reduce the constraints that limit the definition and study of psychological phenomena in community settings (Schneider, 1990). As these constraints are addressed, new social norms can be established to expand and diversify the research process. There are some explicit positive side effects that can occur. A new working social structure can be created for how universities and communities can be resources for each other.The four topics I have presented are agendas for keeping at the task of generating active and expanding scientific traditions. These topics when addressed in the context of collaboration with other disciplines and citizens can develop an empirical base of shared wisdom about how to carry out community psychology research. In these ways the benefits of community psychology research can become more empowering for the public and more and more systemic for the scholar.These comments were presented as an Invited Address at the 2nd annual meeting of the American Psychological Society, June 8, 1990, Dallas, Texas.The following persons took time to read and comment on earlier drafts of these comments.

On the relation between metacontrast masking and suppression of visible persistence

Does the introduction of additional contours in a display sequence (an operation known to reduce the strength of suppression in metacontrast) also reduce suppression of visible persistence? In three experiments, duration of visible persistence was estimated by a method in which successful performance depends on the temporal integration of a pattern whose elements are displayed in two successive frames. In this procedure, the arrival of the trailing frame is known to exert a suppressive influence on the visible persistence of the leading frame. Embedding the elements of the leading frame within additional contours (a line grid) reduced the degree of suppression exerted by the trailing frame. This did not occur when the grid was part of the trailing display. We conclude that suppression of visible persistence and metacontrast masking belong to the same class of events.
