Levels of stress-related illness are generally modeled by including a nonlinear multiplicative or "buffering" effect, corresponding to the interaction of stressor levels with social support from family and friends. The motivation of the present research is to extend an iterative, dynamic model of this well-investigated psychological process using a dynamical systems model expressed as a set of continuous, nonlinear differential equations similar to those of the "Oregonator," a model of a nonlinear dynamic chemical system. This model of the behavior of an individual is amenable to numerical investigation of its stationary-state stability properties, temporal evolution, and cause-effect relationships. The continuous variables in this new approach refer to varying states of an individual; they are Perceived stress (X), Symptoms (Y), and Social support (Z). It is expected that poor health in this model, represented by Symptoms (Y), is directly related to Perceived stress, as well as being tied in more complicated ways to Social support. A number of such models may be envisioned, some including a multiplicative, "buffering" (− X × Z) effect of social support dependent on stress levels. We explore the behavior of this model over ranges of parameter values and initial conditions and relate these results to how an individual reacts to environmental challenges at various levels of stressors and social-support recruitment. Data generated by the model are in turn analyzed with a traditional cross-sectional statistical technique. Similarities and differences between chemical and psychological systems are discussed.

No such overlap is observed in the area of divergent thinking. A battery containing five creativity measures was administered to a group of college student subjects scoring high on either the Perceptual Aberration Scale or the Magical Ideation Scale (N = 52) and to a group of control subjects (N = 65). A multivariate analysis of variance indicated that subjects high on the schizotypal traits of Perceptual Aberration or Magical Ideation (Per-Mag subjects) differed significantly from control subjects on the five creativity tests. Per-Mag subjects scored significantly higher than control subjects on the Barron-Welsh Revised Art Scale, a measure of preferences for figures, and the How Do You Think, a biographical and personality measure. There was a tendency for female Per-Mag subjects to score higher than female control subjects on the Domino Creativity Scale of the Adjective Check List. Per-Mag and control subjects did not differ on the Gough Creative Personality Scale of the Adjective Check List or on the Alternate Uses test, a test of divergent thinking. Per-Mag subjects who scored above the median for their group and gender on the Impulsive Nonconformity Scale received the highest creativity scores on the Barron-Welsh Revised Art Scale and the How Do You Think, although these results only approached significance. These findings argue for the specificity of areas of similarity and difference in schizotypy and creativity.

One model of interpersonal problem-solving skills presents a sequence of receiving, processing, and sending skills. Social perception skills best fit the first stage in this model: receiving skills. As expected, schizophrenic subjects (N = 29) were less skillful than normal subjects (N = 15) on measures of social problem solving, understanding of social sequences, and social judgment. In addition, performance on these tasks was significantly related to nonverbal social perception, but only for the schizophrenic group. Thus, deficits in nonverbal social perception are related to other measures of social functioning in schizophrenia. Implications of these findings for understanding and treating social deficits in schizophrenia are discussed.

Schizophrenic patients (n=28) and normal controls (n=28) were given the profile of nonverbal sensitivity test (PONS). Patients' symptoms were rated with the brief psychiatric rating scale (BPRS). Schizophrenic subjects performed significantly more poorly than normal subjects in their ability to decode nonverbal cues. In addition, normal subjects improved their accuracy significantly more than patients when provided with additional cues per scene to decode. The patients' total PONS score was not significantly correlated with the BPRS summary scores for positive or negative symptoms, but was significantly correlated with the individual positive symptom of conceptual disorganization. Subjects classified as having paranoid schizophrenia (n=11) on the basis of chart diagnoses performed significantly better on the PONS than did undifferentiated schizophrenic subjects (n=13). The discussion reviews how these results contribute to our understanding of social deficits in schizophrenia.

Subjects scoring high on Perceptual Aberration/Magical Ideation (Per-Mag subjects), Anhedonia, and low-scoring control subjects were compared for scores on Hassles and Uplifts, cognitive appraisal, coping strategies, emotions in two stressful situations, and on perceived social support. The groups differed in their experiences of minor life events and Secondary Appraisal but not in Primary Appraisal or emotions. There were notable differences in coping patterns and perceptions of social support. Per-Mag subjects contrasted with controls in using more coping by Escape-avoidance and Accepting responsibility, and reported less social support. Anhedonic subjects differed in their experience of minor life events and coped less through Positive reappraisal and Seeking social support. Per-Mag subjects are mainly distinguished by their coping processes. Anhedonic subjects are also sensitive to the incidence of minor life events. The results indicate that risk factors, stress, and coping interact in the absence of mental disorder.

Overall and within groups, negative symptoms decreased and positive symptoms increased. While the sums of the SANS scores for the schizophrenic patients were initially higher, their mean SANS score dropped more over time (P < 0.001), to show no difference from non-schizophrenics at follow-up. Positive symptoms increased in both groups, although schizophrenics were higher at both times; sub-scales within the SANS showed different patterns of change. Support is found for a multidimensional view of both positive and negative symptoms and for a reconsideration of the notion of 'progressive downward course' in schizophrenia.
