Assessing violent offending in serious juvenile offenders

The convergent validity of the two most frequently used methods for assessing violent offending in juveniles (i.e., selfreports and arrests) was evaluated. Participants were 87 serious juvenile offenders and their maternal figures, primarily from disadvantaged families. Validation measures tapped established behavioral, family, and peer correlates of delinquency. Results failed to support the ability of either arrests for violent crimes or selfreported violent offenses to index violent criminal behavior accurately. Several methodological features of the study support our hypothesis that the findings were not spurious. Procedural and conceptual implications of the findings are discussed.The Family and Neighborhood Services Project was funded by Grant 2H87MH43557-04 to the South Carolina Department of Mental Health from the National Institute of Mental Health.

IF ATTITUDES AFFECT HOW STIMULI ARE PROCESSED, SHOULD THEY NOT AFFECT THE EVENT-RELATED BRAIN POTENTIAL?

Abstract— In Experiment 1, subjects completed an attitude survey to identify items toward which they held positive and negative attitudes. Subsequently, subjects were instructed to count the number of positive (or negative) stimuli in a series. Each series contained six attitude stimuli from a given semantic category (e.g., fruits), and the structure of the series was varied so that positive and negative stimuli, as indexed by subjects' idiosyncratic attitudes, were evaluatively consistent or inconsistent within the series. In Experiment 2, subjects were exposed to personality traits that were positive or negative in series of six. Again, the structure of the series was varied so that positive and negative traits were evaluatively consistent or inconsistent within the series. Results of Experiments 1 and 2 indicated that although the event-related brain potential did not differ as a function of stimulus valence per se, evaluatively inconsistent, in contrast to consistent, stimuli evoked a larger amplitude late P300-like positive component that was maximal over the centroparietal region.     

Smell and taste function in the visually impaired

Surprisingly few quantitative studies have addressed the question of whether visually impaired individuals evidence, perhaps in compensation for their loss of vision, increased acuteness in their other senses. In this experiment we sought to determine whether blind subjects outperform sighted subjects on a number of basic tests of chemosensory function. Over 50 blind and 75 sighted subjects were administered the following olfactory and gustatory tests: the University of Pennsylvania Smell Identification Test (UPSIT); a 16-item odor discrimination test; and a suprathreshold taste test in which measures of taste-quality identification and ratings of the perceived intensity and pleasantness of sucrose, citric acid, sodium chloride, and caffeine were obtained. In addition, 39 blind subjects and 77 sighted subjects were administered a single staircase phenyl ethyl alcohol (PEA) odor detection threshold test. Twenty-three of the sighted subjects were employed by the Philadelphia Water Department and trained to serve on its water quality evaluation panel. The primary findings of the study were that (a) the blind subjects did not outperform sighted subjects on any test of chemosensory function and (b) the trained subjects significantly outperformed the other two groups on the odor detection, odor discrimination, and taste identification tests, and nearly outperformed the blind subjects on the UPSIT. The citric acid concentrations received larger pleasantness ratings from the trained panel members than from the blind subjects, whose ratings did not differ significantly from those of the untrained sighted subjects. Overall, the data imply that blindness, per se, has little influence on chemosensory function and add further support to the notion that specialized training enhances performance on a number of chemosensory tasks.     

Using the Bender-Gestalt test to predict graphomotor dimensions of the Draw-A-Person test

The investigators examined four correlated aspects of the Bender-Gestalt and the Draw-A-Person tests. Subjects were 41 boys and 14 girls classified as seriously emotionally disturbed or seriously behavior disordered by their school system in southwest Georgia. Each subject's Bender-Gestalt and human figure drawings were placed on a digitizing pad and encoded to provide information relative to the width, height, average point of location on the fourth quadrant abscissa and ordinate of each drawing. The widths of Bender Figures 2 and 8 correlated significantly with the widths of human drawings; the heights of Figures A, 5, and 7 were significantly correlated with the heights of the human drawings. Bender Figure 1 was significantly correlated with average points of location on the abscissa of human figure drawings (distance from the left margin of the page), but correlations between the average points of location from the top of the page were nonsignificant. Comparison of these results with data from other samples might refine diagnosis.     

Ethnic populations: Community mental health services ten years later

In a replication of a series of studies conducted by Sue and colleagues in the mid-1970s, demographic and service data were retrieved for the Seattle-King County area from the Washington Mental Health Information System. Caucasian clients were compared against Asian, black, Hispanic, and Native American client groups, and, where possible, against the findings reported earlier by Sue. These clients were compared in terms of basic demographic characteristics, characteristics of staff providing the services, dropout rates, and average number of services received. The most notable findings are (a) that failure-to-return rates are dramatically lower for the current sample than for Sue's and not greatly different for minorities than for Caucasians, (b) that variability in failure-to-return rates is most strongly related to level of functioning and not related to minority status, and (c) that although Asian Americans still average fewer services than Caucasians (other minorities do not differ significantly), the mean number of services had increased substantially for all groups but more for minorities than for Caucasians.     

Relations among aspects of children's social environments,gender schematization,gender role knowledge,and flexibility

Sixty 33–60-month-old children's gender role knowledge, gender role flexibility, and gender schematization were assessed. Parents completed questionnaires describing aspects of their child's social environment. Results indicated that boys who reportedly interacted more with their fathers, and girls who interacted more with both parents, exhibited greater gender schematization. Children who interacted more with parents displayed less gender role flexibility. Girls with mothers who worked outside the home demonstrated greater gender role flexibility. Boys with many siblings displayed greater gender role knowledge. Children with fewer siblings displayed greater gender role flexibility. Boys favoring entertainment television demonstrated greater gender role knowledge. Girls favoring educational television displayed greater gender role flexibility. Future research and theory evaluating the interactive effects of social and cognitive factors on boys' and girls' gender role development are encouraged.     

Medical malpractice and the legal standard of care

In this essay, I examine the relationship between lawsuits for medical malpractice and the legal standard of care. I suggest that there is an insidious, dynamic relationship between physicians' reactions to the recent increase in malpractice litigation and an artificial elevation of the legal standard of care. Since, that is, the legal standard for proper medical care is based upon the community standard of care rather than the reasonable person standard, to the extent that overtreatment or “defensive” medicine becomes widespread as a reaction to malpractice litigation, the legal standard becomes elevated as well. Thus, it will increasingly be the case that unless a physician practices defensive medicine, and hence practices unreasonably, she risks being found liable for medical malpractice.     

Visually presented verbal stimuli by assembly language on the Apple II computer

A method for programming real-time experiments employing visually presented verbal stimuli is described for the Apple II computer. Applesoft BASIC is used to load the stimuli and write the data file, but assembly language controls all aspects of the experimental trials. The method is illustrated for a lexical decision experiment; however, it readily extends to semantic priming, recognition, sentence verification, and single- or multiple-line reading experiments. The method maximizes both precision and stimulus capacity.     

Sex differences in ambulation and defecation in the degu (Octodon degus)

The degu, a hystricomorph rodent, was studied in both an open-field (OF) and running-wheel testing situation. Of primary interest was whether there would be appparent sex differences in ‘emotionality’ and/or locomotion measures. Unlike domesticated species, females were found to ambulate and defecate more frequently than males in the OF. Both sexes increased their rates of defecation with exposure to the field. The running-wheel data indicatedf that overall males were more active, particularly during the dark phase of the light cycle. The data are examined with respect to similar measures obtained from domesticated laboratory rodents.
