Psychometric detection of schizotypy: perceptual aberration and physical anhedonia in relatives of schizophrenics.

We administered scales of Perceptual Aberration (PERAB) and Physical Anhedonia (PHYSAN), traits that may be related to risk for schizophrenia, to 54 schizophrenics, 146 of their first-degree relatives (evaluated for schizophrenia-related disorders), and 178 normal subjects (screened for psychotic disorders in them or their relatives). For both scales, there was a significant effect of group membership. For the PERAB scale, the schizophrenics had higher scores than the normal subjects, who had higher scores than the relatives. For the PHYSAN scale, schizophrenics had higher scores than their relatives, who had higher scores than the normal subjects. Patterns of familial correlations also suggested that physical anhedonia, but not perceptual aberration, may be familial among schizophrenics and their relatives. The PHYSAN scale, but not the PERAB one, may be a useful indicator of liability for schizophrenia among the relatives of affected probands.     

Primordial Image and the Archetypal Design of Art

This paper extends Jung's work on the relationship of art to (postulated) archetypes of the collective unconscious. Archetypes of the collective unconscious, according to Jung, are revealed to ego consciousness only by way of images--images of a specific form. Jung suggests that archetypes, primordial images, combine two aspects in a single form and are therefore paradoxical. The wise old man and youth and hermaphrodites illustrate Jung's definition of a primordial image. My study of Jung's illustrations concludes that he is referring to what I term double-figures as the design form of primordial imagery. I elaborate upon the design form of double-figures, and illustrate my conception of archetypal imagery through comparative analysis of nine cases of double-figure imagery from selected prehistoric and contemporary societies. Double-figures, as archetypal primordial imagery of the collective unconscious, are spontaneously generated, autonomous, and known to a wide variety of societies. I distinguish between form and content in the study of primordial imagery, and conclude with a summary of the importance of Jung to the cross-cultural study of art.     

Some values guiding community research and action

The dual purposes of applied research-contributing to understanding and improvement-are only partially served by method systems that encourage studying (with increasing precision) a narrow range of questions of modest societal importance. To optimize contributions to challenging societal problems, a field's cherished standards should be adapted to support more adventuresome forms of community research and action. This paper outlines 10 values for community research and action, based on insights from the fields of behavioral and community psychology. These values-reflect the goals and challenges of establishing collaborative relationships with research participants, determining research goals and methods, designing and disseminating interventions, communicating research findings, and advocating for community change. Critical challenges are outlined, and implications for the field and its clients are discussed.     

Diagnostic issues in posttraumatic stress disorder: considerations for the DSM-IV

Four issues of key interest with regard to posttraumatic stress disorder in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) are discussed. These include: (a) how to define the stressor criterion, especially, whether or not the victim's response ought to be included and whether low-magnitude traumas qualify etiologically; (b) the cohesiveness of the syndrome and the validity of items across stressor groups; (c) the position of posttraumatic stress disorder within DSM-IV; and (d) comorbidity with other illnesses.     

Multifactorial assessment of bulimia nervosa

We investigated a multifactorial approach to the assessment of bulimia nervosa by means of hierarchical factor analysis. Two hundred forty-five bulimia nervosa patients and 68 patients with either anorexia nervosa or eating disorders not otherwise specified were administered a self-report battery that was organized into 21 dimensions relevant to eating disorder patients. When dimensions from this battery were subjected to hierarchical factor analysis, support for bulimia nervosa as a unique diagnostic category was obtained. However, the emergence of 3 secondary factors and 6 primary factors suggests that bulimia nervosa can also be described more complexly. The emergence of a multifactorial model of bulimia nervosa that incorporates several existing undimensional models suggests the potential for both divergent and complicated clinical presentation in bulimia nervosa patients.     

Group treatment of the hyperventilation syndrome

Hyperventilation (hv) is increasingly recognized as being significant in a number of psychological and medical conditions. The core of treatment for hv is breathing retraining, usually on an individual basis. This article describes a group therapy for breathing retraining for patients with hv-induced panic reactions. An analysis of group process suggests that such treatment is helpful in ways impossible for individual retraining and that further exploration of this modality is warranted.     

Processing of threat-related information in rape victims

We investigated selective processing of threat information in persons with posttraumatic stress disorder (PTSD) by using a modified Stroop procedure. Subjects were 15 rape victims with PTSD, 13 rape victims without the disorder, and 16 nontraumatized control subjects. They were asked to name the color of four types of words: specific threat (rape-related) words, general threat (related to physical harm and death) words, neutral words, and nonwords. Rape victims with PTSD evidenced a longer response latency for color naming of rape-related words than for other target-word types. Response latencies of non-PTSD victims and nonvictim control subjects did not differ across word types. Possible mechanisms underlying the selective processing of threat material are considered, and clinical implications are discussed.     

Personality Characteristics and Self-esteem in Pet Owners and Non-owners

Previous research suggests that pet owners are psychologically different than non-owners in terms of self-esteem and other personality characteristics. In this study, 82 pet owners and 48 non-owners were tested on self-esteem, extraversion, neuroticism, and social self-esteem. Special emphasis was placed on highly attached pet owners compared with non-owners. Level of attachment was determined by scores from the CENSHARE pet attachment survey. No significant differences were found between the groups using analysis of variance and multivariate analysis of variance statistical procedures. It was concluded that pet owners and non-owners may not be different in terms of personality but may have become victims of stereotyping by both the general population and scientific researchers. Discussion was given to related significant findings and recommendations for further research.     

Familial aggregation of a developmental language disorder

This paper investigates the etiology of developmental dysphasia and its linguistic properties. Data are presented that suggest that at least some cases of dysphasia are associated with an abnormality in a single dominant gene. The results of a series of tests on a large three-generation family, in which half of the members have dysphasia, are reported. These results show that abstract morphology is impaired in these subjects. It is argued further that the data are consistent with the hypothesis that the dysphasics learn the feature-marked lexical items of language as unanalyzed lexical items. They do not have the underlying capacity to learn language by constructing paradigms.
