The relationship between neurocognitive impairment and employment in a cohort of 130 predominantly symptomatic individuals with HIV-1 infection was examined. Participants were classified as employed (full or part-time for pay) or unemployed (N 5 64) and administered a neuropsychological test battery. When covarying for CD4 count, age, and physical limitations, the results revealed that unemployed men performed below that of employed participants on tasks of memory, set shifting-cognitive flexibility, and psychomotor speed. The results are discussed within the context of similar findings in other illnesses. (JINS, 1999, 5, 534-539.)

Central venous catheter insertion is commonly performed in the neck by using the right internal jugular vein. This study assesses factors affecting the cross-sectional area of this vein during central venous catheterization.

This study was designed to examine hypothesized differences between sex offending and nonoffending Roman Catholic clergy on cognitive mediation abilities as measured by the Rorschach Inkblot Test (H. Rorschach, 1921/1942). This study compared 78 priest pedophiles and 77 priest ephebophiles with 80 nonoffending priest controls on the Inkblot test using J. E. Exner's (2003) Comprehensive System. The three groups were compared on seven variables that constitute Exner's Cognitive Mediation cluster. Additionally, the groups' coping styles were compared to examine the interaction of coping style and cognitive mediational abilities. We found interactions between coping style and offending status across most of the cognitive variables indicating impairment in the mild to pathological ranges. Moreover, significantly higher unusual thinking styles (Xu%) and significantly lower conventional thinking styles (X+%) in offenders compared to nonoffenders. Those with an Extratensive style (n=31) showed significantly higher distorted thinking when compared to the Introversive (n=81), Ambitent (n=73), and Avoidant (n=50) coping styles. This study suggests that offenders display significantly higher distorted thinking styles than do nonoffenders. Possible reasons for these discrepancies and the role of coping styles in abusive behaviors were discussed.

This study examined response discrimination (d') and bias (likelihood ratio) differentials in a computer-generated test of auditory and visual attention functioning. Patients with bipolar disorder (n=42) and schizophrenia (n=47) were contrasted to a normal comparison group (n=89) in two conditions: (a) simple modal responsivity (auditory and visual stimuli) and (b) ipsimodal (auditory/auditory and visual/visual) and crossmodal (auditory/visual and visual/auditory) responding. The results of this study indicated that in the simple modal condition both subject groups showed differential modal preferences but in opposite directions. The schizophrenic group showed a significant visual over auditory preference, committing more auditory commission and omission errors than visual errors. The bipolar group displayed a distinct auditory over visual response preference, committing significantly higher number of visual omission errors. Response bias analysis indicates that both diagnostic groups adopted a more liberal response bias, whereas the comparison group assumed a more conservative approach. For all groups response sensitivity improved as response bias became more neutral. The modal switching results indicated that all three groups tended to commit more commission errors (false alarms) in the auditory crossmodal switching condition (visual/auditory) by comparison with the other switching conditions. Between group comparisons for this condition showed that the schizophrenic group committed significantly more commission errors than the other groups. No significant medication effects were detected.

This cross-sectional study examined modal attention asymmetries in patients with schizophrenia (n = 47) and bipolar disorder (n = 42), as contrasted to a matched-sample comparison group of normal participants (n = 89). A test of continuous auditory and visual attention was the primary measure. The data were analyzed from 2 experimental conditions: simple modal responses (auditory and visual) and modal switching responses (ipsimodal and cross-modal switching). In the simple modal condition, patients with schizophrenia demonstrated a visual over auditory asymmetry; patients with bipolar disorder showed no differences. In modal switching conditions, however, patients with bipolar disorder displayed a significant auditory over visual asymmetry. No main effect was detected between medications and attention functioning. Results are discussed in light of differentiating these 2 populations on the basis of modal specificity of attention functioning.
