Central auditory processing : III. The “cocktail party” effect and anterior temporal lobectomy

The capacity to selectively attend to only one of multiple, spatially separated, simultaneous sound sources—the “cocktail party” effect—was evaluated in normal subjects and in those with anterior temporal lobectomy using common environmental sounds. A significant deficit in this capacity was observed for those stimuli located on the side of space contralateral to the lobectomy, a finding consistent with the hypothesis that within each anterior temporal lobe is a mechanism that is normally capable of enhancing the perceptual salience of one acoustic stimulus on the opposite side of space, when other sound sources are present on that side. Damage to this mechanism also appears to be associated with a deficit of spatial localization for sounds contralateral to the lesion.     

Alcoholics in inpatient,short-term interactional group psychotherapy: an outcome study

The differential outcome of 100 psychiatric inpatients distinguished by the presence/absence of secondary alcoholism was examined in shortterm closed group psychotherapy. Alcoholics did not differ from the general sample in outcome, but displayed distinct active/aggressive personality features. Group outcome was not affected by the presence/absence of alcoholic members.     

The influence of psychoticism and extraversion on classical eyelid conditioning using a paraorbital shock UCS

An experiment is described in which the effects of Psychoticism and Extraversion on classical eyelid conditioning were examined using a balanced design involving two levels of paraorbital shock intensity and two levels of response threshold. Questionnaire measures of Anxiety and Impulsivity were also analysed together with subjective ratings of the UCS. Results were broadly consistent with Eysenck's personality theory in that subjects scoring high on Psychoticism demonstrated lower levels of conditioning.

Participation by women in behavior analysis

The participation of women in behavior analysis as authors of articles published in the Journal of the Experimental Analysis of Behavior (JEAB) and the Journal of Applied Behavior Analysis (JABA), as members of the Association for Behavior Analysis (ABA), and as contributors to the 1982 ABA convention was examined. Since the inception of JEAB and JABA, men have appeared as authors far more frequently than women, although women have published relatively more frequently in the latter journal than in the former. Across years, there has been an upward trend in the proportion of JEAB authors who are female; this is not the case for all JABA authors, although it does hold for senior authors. In 1980-1981 and 1981-1982, females represented approximately half of ABA's student and affiliate members but less than a third of its full members. Approximately a third of the contributors to posters and symposia and a seventh of those delivering invited addresses at the 1982 ABA convention were women.     

Tailoring sex-education programs to adolescents--a strategy for the primary prevention of unwanted adolescent pregnancies

The data for this paper were derived from 88 unstructured interviews conducted with a purposive sample of adolescents from September 1978 through July 1979. We content analyzed all interview abstracts with particular emphasis on the comments and suggestions made by adolescents in regard to sex education in order to ascertain their needs. Three areas in need of immediate revision were identified--curriculum, format, and lecturer. Respondents also provided a variety of suggestions which can be used by educators and planners in developing and implementing sex-education programs; thereby making programs sensitive to the expressed needs and wants of adolescents. This qualitative study supports the findings of many quantitative studies which found that many adolescents do not have, yet want, sensitive sex-education programs.     

Educational,social, and psychological correlates of vocational maturity

An investigation of the educational, social, and psychological correlates of vocational maturity was undertaken in an Ontario high school involving a sample of 272 students. The analysis of data revealed that the students' CMI scores were generally correlated with (i) their educational and occupational aspirations, (ii) self-estimates of their general ability and classroom performance, (iii) their parents' educational level, and (iv) educational and occupational aspirations parents held for them. It was found moreover that higher CMI scores were associated with higher self-esteem, more internal locus of control, and more intrinsic work values. Implications of the results are discussed for educational practice.     

Feature-positive effect in adults and attention to portion of stimulus array

In three experiments, adult humans were tested in a feature-positive or feature-negative simultaneous symbol task. In Experiment 1, some persons focused on the correct side of the stimulus cards, whereas other persons focused on the not-correct side of the stimulus cards. The feature-positive group learned faster than the feature-negative group did in the correct side condition; the feature-negative group learned faster than the feature-positive group did in the not-correct side condition. In Experiments 2 and 3, all persons focused on both the correct and not-correct sides of the stimulus cards. Under these circumstances, feature-positive and feature-negative performances were comparable. These results indicated that the usual superiority of feature-positive over feature-negative learning results from a tendency to attend to only a portion of the stimulus array.     

The effects of vicarious experience and stimulus intensity on pain termination and work avoidance

The purpose of the present investigation was to evaluate the role of vicarious experience in the acquisition of pain termination and work avoidance. Fifty-six experimental subjects were randomly assigned to view a film of a model who either terminated exposure to a pain stimulus and work task after 10 sec (high-avoidant) or 70 sec (low-avoidant). Following the film presentation, subjects were exposed to the pain stimulus and work task. Half of the subjects were randomly chosen to perform the task with a low-intensity pain stimulus (LP) and the other half performed the task while exposed to a high-intensity pain stimulus (HP). The results indicated that subjects in the high-avoidant model conditions (HA) did significantly less work and tolerated the pain stimulus for significantly fewer seconds compared to the low-avoidant model groups (LA). Subjects in the LP groups tolerated the pain stimulus significantly longer and did significantly more work compared to subjects in the HP groups. No significant interaction was observed. The results provide support for the hypothesis that behavioral reactions to pain can be acquired by vicarious experience. Implications for future research are discussed.
