Neuromuscular circuits in affect-laden information processing

Substantial evidence has accrued indicating the involvement of neuromuscular circuits in covert information processing. The physiological systems impartingemotional tone to covert processing, however, are less well understood. Reviewed here are findings from a variety of methodologies which suggest that somatic patterns, particularly in the face, reflect moment by moment emotional reactions. These findings imply neuromuscular involvement in affect-laden information processing; less conclusive, though suggestive, are data indicating that the proprioceptive feedback from these phasic and specific patterns of response are integrated cortically and influence covert processing and overt responding.     

Peer tutoring among elementary students: educational benefits to the tutor

To determine whether tutoring might be academically beneficial to the tutor, this study investigated the acquisition of spelling words by three elementary students in a peer tutoring program. The experimental design allowed a simultaneous comparison of each child's gain in performance on comparable word lists on which the child tutored another child, was tutored by another child, or neither gave nor received tutoring. The children's spelling improved nearly an equivalent amount on those words on which they tutored another child as on the words on which they were tutored; no such change was noted on the words on which they neither gave nor received tutoring. These findings, that peer tutoring is profitable for the tutor as well as the tutee, provide a basis for recommending peer tutoring as one method of individualizing education.     

Alcohol and human sexual behavior.

Despite the potential clinical significance of the relationship between alcohol consumption and human sexual responsiveness. the subject has received little systematic research attention. Clinical observations have suggested that alcohol abuse can lead to impotency disorders in males and sexual dysfunction in women. Alcohol has been associated with sex offences such as rape and pedophilia, increased sexual activity and extramarital affairs. However, correlation has been confused with cause, and unequivocal evidence of alcohol as the causal agent is lacking. Recent research using penile tumescence and vaginal pressure pulse as measures of sexual arousal has shown a significant negative linear relation between alcohol and sexual responsiveness in both men and women social drinkers. Findings that cognitive rather than pharmacological factors decisively influence alcohol's effects on sexual arousal, together with other psychosocial analyses, dispute the disinhibition hypothesis of alcohol's effects. A social learning analysis of alcohol's influence on sex is proposed.     

A controlled trial of the treatment of nocturnal enuresis in residential homes for children

The present study was undertaken to evaluate the practicability and efficacy of treating enuretic children in residential Children's Homes by means of the enuresis alarm. A control group design was employed with 19 and 20 subjects in the treatment and control groups respectively. Eighteen of the nineteen treatment group children achieved initial arrest of enuresis in a mean of 11.9 weeks of treatment (range 5–28 weeks). Over the initial 12-week period, the treatment group showed a statistically significant reduction in mean wetting frequency, both over time and in comparison with the control group. After a follow-up period of at least 20 months. 17 of the 19 children were known to be dry. The results of an independent evaluation are reported, and it is concluded that alarm treatment is as effective and practicable in Children's Homes as it is in family situations.     

Reducing Counselor Anxiety by Using Modeling Strategies

We hypothesized that beginning counselors experience interview-related anxiety that affects counselor performance. Two kinds of videotaped modeling—an expert model approach and a coping model approach—were compared as to the relative effectiveness of each method in reducing beginning counselors' anxiety toward a counseling interview. Those persons who viewed expert models significantly reduced situationally related anxiety following participation in an analogue interview. Persons who viewed coping models had nominal but nonsignificant reductions in anxiety. In neither group was anxiety significantly related to counselor performance. A modicum of anxiety may be a desirable attribute in beginning counselors. The relative merit of each kind of modeling strategy is discussed.     

Effects of selective forebrain noradrenaline loss on behavioral inhibition in the rat.

Virtually total depletion of cortical and hippocampal noradrenaline by stereotaxic injection of 6-hydroxydopamine into the fibers of the dorsal noradrenergic bundle produced no impairment in acquisition learning of a runway response for food reward. Extinction of this response, once learned, was markedly slower in the treated group than in controls, the treated animals perseverating in rapid running to the goal box even with no food present there. Similarly, no impairment was found on acquisition of a continuously reinforced lever-pressing response for food. Extinction of this response, however, was again slower in the treated group. Subsequent acquisition of a successive light-dark discrimination task was also slower in the treated group, with these animals perseverating in responding to the negative stimulus. Although selective forebrain noradrenaline loss does not impair the acquisition of appetitive responses, the suppression of responses in the absence of reward is impeded. A parallel is drawn with those effects found classically after surgical lesion to the hippocampus.
