Considering the explanations of schizophrenia that presume schizophrenia spectrum disorders (e.g., schizotypal personality disorder, schizoaffective disorder, etc.) to be genetically related to schizophrenia, the purpose of this study was to investigate the attention and information processing abilities of individuals who have been identified as schizotypal or psychosis-prone (i.e., schizophrenia spectrum functioning in individuals who do not have schizophrenia). Research indicates that persons identified as psychosis-prone may show attention and information processing deficits similar to individuals with schizophrenia. The identification and description of individuals who later decompensate into schizophrenia would advance the understanding of schizophrenia and its causes. The Chapman's PER-MAG scale (Perceptual Aberration-Magical Ideation) was used to identify 35 hypothetically psychosis-prone college students (schizotypy group) and 42 normal college students (nonschizotypy group) out of the 806 volunteer subjects. Their attention and information processing abilities were measured by COGLAB (a multiparadigmatic cognitive test battery that represents a continuum of cognitive functions, from preattentional to attentional, to conceptual). Their social adjustment was measured by the Premorbid Adjustment Scale (PAS). The hypotheses of the study were that the hypothetically psychosis-prone subjects would perform poorer than controls on COGLAB measures and that COGLAB measures of a more molar nature would better predict social adjustment …

Review of previous research on cultural differences in pain experience and/or pain behavior revealed that cultural affiliation affects pain perception and response. Unfortunately, the many inconsistent findings in the literature on cultural differences in pain experience and behavior have made interpretations and comparisons of results problematic. These inconsistent findings could be attributed to variations in acculturation level among cultural groups. The purpose of this study was to investigate cultural differences in pain experience (assessed by McGill Pain Questionnaire, the Box Scale, the Headache Pain Drawing, and the Headache Questionnaire) and pain behavior (measured by determining medication use and interference of daily functioning due to headaches) among Mexican (n = 43), Mexican American (n = 36), and Anglo American (n = 50) female chronic headache pain sufferers. The contribution of acculturation to differences in pain experience and behavior among cultural groups was measured by the Acculturation Rating Scale for Mexican Americans. The three cultural groups of women significantly differed on pain experience and pain behavior. Specifically, Mexican women experienced their headache pain more intensely, severely, and emotionally than Mexican American and Anglo American women. Furthermore, Mexican women were more willing to verbally express their pain than the other two groups. As …

The purpose of this study was to examine how parental separation is related to eating disturbances and assertiveness in females who struggle with bulimic symptoms. Two-hundred ninety-two undergraduate females from the University of North Texas comprised the subject group. Using pen and paper measures of assertiveness, bulimia, and parental separation, support was found for the prediction that there would be a relationship between assertiveness and parental separation. Likewise, partial support was found for the prediction that there would be a relationship between bulimia and parental separation. Parental separation was found to affect levels of bulimia and assertiveness. Finally, it was found that subjects endorsed greater emotional independence from fathers than from mothers.

The current study examined if students' levels of social physique anxiety vary depending on the type of exercise setting they select. The study determined the degree to which social physique anxiety changed over the course of semester-long involvements in different exercise settings.

Self-concept scores of 19 visually-impaired adults were compared to those of 19 matched sighted adults using the Tennessee Self-Concept Scale (TSCS). All participants attended the University of North Texas. Scores were examined against the Vocabulary and Information subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R).

This study examined the neurocognitive skills, incidence of mild head injury, incidence of learning disabilities, and study habits among college students with grade point average of 2.00 or below (N = 25) as contrasted with college students with grade point average above 2.00 (N = 70). The intent of this research was to extend the work of Segalowitz and Brown (1991) and Segalowitz and Lawson (1993) who found significant associations between reported history of mild head injury and developmental disabilities among high school and college samples. MANOVAs conducted on measures of academic achievement, global cognitive skills, verbal and nonverbal memory, motor and tactile functioning, and study habits did not discriminate between probationary and non-probationary students. Probationary and non-probationary students also did not differ with regard to incidence of reported head injury, frequency of diagnosed learning disabilities, and study habits. Measures of neurocognitive functioning and study habits did not contribute to the prediction of grade point average over and above that predicted by Scholastic Aptitude Test composite score. Several exploratory analyses were performed examining the relationship between study habits and neurocognitive skills. Gender differences, implications for future research and development of study skills courses, and limitations of this study were discussed.
