Child Behavior Profile types in a general population sample of boys 6 to 11 years old

Characteristics of Child Behavior Profile (CBP) types were studied in a general population sample of 202 boys aged 6 to 11 years. Parents completed the Child Behavior Checklist and teachers simultaneously rated the Teacher's Report Form. Overall, 39.7% of the boys were classified within a CBP type: 28.8% Internalizing and 10.9% Externalizing. The most common specific type was Somatic Complaints. Teachers rated the Externalizing CBP boys as showing robust externalizing behaviors in school. Also, boys with Externalizing profile types showed severe degrees of psychopathology in both home and school environments. An intraclass correlation of 35 or greater was found to identify boys with sufficiently severe psychopathology to warrant further clinical evaluation. Findings in this general population sample appear consistent with previous results in outpatient samples, and extend our understanding of the validity and clinical value for CBP types.     

Body image and comprehension of body part names

The relation between awareness of body topology and auditory comprehension of body part names was studied in 22 aphasic subjects. Two nonverbal tasks—human figure drawing and placement of individual body parts in relation to a drawn face—were compared with two auditory tests of body part comprehension. The two nonverbal and the two verbal tasks were closely correlated with each other, but there was no relation involving either of the verbal tests with either of the nonverbal tests. Selection errors in the auditory comprehension tasks were predominantly semantically based and equally distributed between functionally analogous parts and parts related by location on the body.Dr. Benedet's effort in this study was supported by a grant from the Hispano-North American Joint Committee for Cultural and Educational Cooperation.

Perceptual and motor factors in the imitation of simple temporal patterns

Summary This study investigated the relative importance of perceptual and motor factors in the imitation of simple temporal patterns. Previous research in which subjects tap out interval sequences using one finger has suggested that perceptual factors play an important role in response timing. Studies of bimanual tapping, in contrast, stress the importance of motor interactions between the two hands. In this experiment we compared the ability of subjects to tap out two-interval sequences using one finger, two fingers on one hand, and two fingers on opposite hands. The results showed almost identical performance under the three response conditions. It is suggested that the perceptual relations between intervals in a pattern were the main determinant of performance in this experiment.     

Overt integrity tests versus personality-based measures of delinquency: An empirical comparison

This study examined the ability of both an overt integrity test and a personality-based measure of delinquency to predict on-the-job theft and counterproductivity. A heterogeneous sample of 105 employees anonymously completed both tests and a criterion checklist that included a 9-item theft subscale and a 12-item counterproductivity subscale. Results indicated that the overt integrity test was a superior predictor of both on-the-job theft and drug abuse compared to the personality-based measure. The overt integrity test was also a slightly better predictor of general counterproductivity. These findings and their implications are discussed.     

The physiology of the tunnel

Several theories to account for the origin of tunnel hallucinations and tunnel experiences near death are considered: (1) the idea of a real tunnel; (2) representations of transition; (3) reliving birth memories; (4) imagination; and (5) physiological origins. Three different physiological theories are considered that related the tunnel form to the structure of the visual cortex. All can account for much of the phenomenology of the tunnel experience, and all lead to testable predictions. It is argued that the tunnel experience involves a change in the mental model of the self in the world. Because of this, an experience of purely physiological origin, with no implications for other worlds or for survival, can nevertheless produce lasting changes in the sense of self and reduce the fear of death.
