Profiles in Problem Solving: Psychological Well-Being and Distress Among Persons with Diabetes Mellitus

Although social problem-solving abilities have been consistently associated with indicators of behavioral health, this work has been largely confined to tests of specific theoretical issues. Research has yet to demonstrate how the separate elements of the social problem-solving model relate to different patterns of adjustment, particularly among persons who live with chronic disease. We studied the occurrence of different profiles of social problem-solving abilities observed among persons living with diabetes mellitus. We then examined differences between clusters on measures of life satisfaction and depression. Results indicate that distinct profiles in problem-solving abilities do occur and these groupings can be distinguished by their different patterns of adjustment. Implications for theoretical models of problem solving and clinical assessment and interventions for persons with diabetes are discussed.     

Perceptual organization in schizophrenia: the processing of symmetrical configurations

The hypothesis that the perceptual organization dysfunction of patients with poor premorbid schizophrenia is due to a deficit in global visual sensory store processing was tested by assessing their ability to process symmetrical configurations that develop early and have strong prepotent structures. Two same-different judgment tasks in which performance varies as a function of the symmetrical organization and task demands were administered to participants with good and poor premorbid schizophrenia, those with mood disorders, and normal controls. Like the other groups, poor premorbid schizophrenics' latency and error response patterns closely paralled the a priori model of adequate processing. The results support their competence in perceptually processing symmetrical configurations and disconfirm the hypothesis that their input deficiencies represent a general deficiency in all forms of perceptual organization. The implications for specifying their early input dysfunction are discussed.     

The influence of walking speed and prior practice on locomotor distance estimation

In an attempt to reconcile discrepant findings in the literature (Elliott, 1986; Thomson, 1983), walking speed, prior practice, and walking delay were manipulated to determine if they had an impact on locomotor distance estimation. Contrary to suggestions by Thomson (1986), walking variability in the direction of locomotion depended only on a subject' initial distance from the targets.
