Individuals diagnosed with schizotypal personality disorder (SPD) exhibit patterns of cognitive deficits in (1) attention (Lees-Roitman, Cornblatt, Bergman, Obuchowski, Mitropoulou, Keefe, Silverman, & Siever, 1997), (2) memory (Bergman, Harvey, Lees-Roitman, Mohs, Margerm, Silverman, & Siever, 1998), (3) executive functioning (Cadenhead, Perry, Shafer, & Braff, 1999), and recently (4) neuromotor functioning (Neumann & Walker, 1999), similar to individuals with a diagnosis of schizophrenia. Furthermore, recent research suggests a link between neuromotor and cognitive functioning in schizophrenia spectrum disorders (SSDs) (Neumann & Walker, 2003). The current study is an extension of research on non-drug-induced neuromotor disturbances in individuals with SPD and examines how such disturbances covary with neurocognitive measures. Approximately thirty-three adults (18-65) were rated for SPD symptoms. Motor assessments included a computerized motor task and finger tapping test. Cognitive assessments included measures of attention, verbal and visual memory, and executive functioning. Consistent with previous research, the SPD group displayed significant right hand (left hemisphere) motor disturbances (i.e., increased force and force variability) compared to healthy controls after excluding all cases reporting a history of head injury. In addition, results indicate significant associations between motor, cognitive, and symptom variables. Consistent with previous research, neuromotor functioning and the relationships between motor and cognitive …

The objective of this study was to examine the relations between Posttraumatic Stress Disorder symptomatology and intelligence. Thirty American combat veterans of the Vietnam War, diagnosed with chronic PTSD, were given a psychodiagnostic structured interview. Participants were assessed for Intelligence Quotient as well as the veracity of their self report. The study found that there were significant differences in how participants experienced their PTSD symptoms that were correlated with intelligence. The higher IQ participants reported more frequent and intense guilt related symptoms as well as more intense intrusive recollections. The lower IQ participants experienced more frequent startle responses, more intense problems related to falling or remaining asleep and more frequent affective symptoms related to emotional numbing. Psychologists could use these differences in how PTSD is experienced in treatment planning. It may be useful for therapy to address sleep disturbances and affective numbing in lower IQ individuals. Therapy for higher IQ individuals may be more useful if it addresses feelings of guilt and intrusive recollections.

This study examined college undergraduates' intercultural experiences and attitudes at the beginning and the end of a semester-long course on multicultural issues. Participants were 290 undergraduate college students at the University of North Texas , 202 of whom were enrolled in one of the university's core global studies, cross-cultural, or diversity courses for the fall 2001 semester, and 88 of whom were enrolled in courses outside the core. It was hypothesized that the multicultural group's Positive Inventory of the Consequences of Multicultural Experiences scores would increase and Social Dominance Orientation Scale scores would decrease more than they would for the control group. Findings did not support these hypotheses.

It has been shown repeatedly that many people hold personality stereotypes of stutterers. The attitudes of psychotherapists regarding stutterers have never been investigated. The present investigation assessed the degree to which psychotherapists-in-training hold stereotypes of stutterers as compared to normally fluent speakers. Two groups viewed a videotaped vignette of a male. In one, the male interviewee displayed stuttering behaviors. In the other, the same male spoke fluently. Participants then rated the male interviewee on several personality dimensions. Contrary to previous findings, the group viewing the stuttering interviewee rated him no differently than did the group viewing the fluent interviewee. Greater knowledge of stuttering was associated with more positive ratings of the person who stuttered. The clinical and research implications of these findings are then discussed.
