Extraversion and attitude towards capital punishment

Male and female Canadian undergraduate students identified as extraverts or introverts on the basis of the Eysenck Personality Inventory were administered a questionnaire measuring attitude towards Capital Punishment. Both effects of sex and personality were significant, males and extraverts reporting stronger beliefs in Capital Punishment than females and introverts. These results were interpreted as providing support for Eysenck's proposal that the social attitude dimension of Toughmindedness reflects the personality trait of Extraversion.     

Computer-Assisted Careers Counselling: A New Approach

This paper describes the outcome of a research and development project concerned to construct a computer aid for careers advisers and career decision-makers which differs in basic philosophy and design from others currentiy in the field. The resulting Careers Decision Aiding System (CDAS) is principally concerned with improving the quality of the decision-making strategy employed by clients by raising their awareness of the way in which their career choice is made, ratherthan with employing computer technology to attempt to match people to careers. The use of the CDAS by clients and careers advisers is illustrated by two case-studies.     

Relationships between judgements of the complexity,pleasingness and interestingness of music

Forty unfamiliar, one-minute samples of modern jazz were rated by 132 undergraduates for judged complexity, pleasingness and interestingness, in a between-subjects design. Pleasingness and interestingness were positively correlated and both were decreasing linear functions of complexity, although the correlation between interestingness and complexity was low and only marginally significant. It appears that pleasingness acts as a suppressor on the interestingness/complexity correlation: with pleasingness partialled out the correlation was positive and highly significant. Partialling had only small effects on the other correlations. Results suggest that techniques used previously to study non-musical stimuli may also be applicable to music.     

Auditory adaptation to gradual rise or fall in intensity of a tone

The auditory system adapts to gradual changes of intensity. After listening to a gradually loudening (or softening) tone, a steady test tone appeared to be growing gradually softer (or louder). “Tuning curves” for these aftereffects were measured by adapting to one audio frequency and testing at another. Softening tones produced larger aftereffects, which were more sharply tuned for audiofrequency, than did loudening tones.     

Electrophysiological and behavioral indicants of selective attention to multifeature gratings

The mechanisms underlying selective attention to gratings consisting of a particular conjunction of spatial frequency and orientation were investigated by means of both visual evoked potential (VEP) and behavioral measures. The effects of selective attention upon the VEP indicated two general types of selection processes: one which is specific to the features contained in the relevant gratings and is most pronounced approximately 225 msec post-stimulation, and another which is specific to the conjunction of features defining the relevant grating and is most pronounced 250–375 msec following the presentation of the stimulus. The behavioral responses primarily reflected this latter, or grating-specific, attentional process. The results are discussed in terms of the role of sensory feature channels in mediating selective attention to visual stimuli and are related to various information processing models of visual pattern selection.     

Generalized and specific expectancies: Sequential mediators of interpersonal behavior1

Two experiments confirmed sequential mediation of social interaction by investigating the effects of generalized expectancies on specific expectancies and the effects of specific expectancies on performance. Both experiments used a simulated tutoring task in which the subject took the role of tutor while a confederate took the role of student. In Experiment 1 subjects combined generalized expectancies about the effectiveness of certain tutoring responses with specific situational information to produce specific expectancies about the results of the tutoring responses under the experimental circumstances. Experiment 2 replicated this finding and showed that specific expectancies of the relative effectiveness of different responses influenced which response was performed more. Results were discussed in terms of cognitive motivation theory and social learning theory.     

Behaviorally-based decision-making training for children

A seven-step, behaviorally based, decision-making process was taught to 17 children, age 9–10 years. Each child's decision-making ability was measured before and after training, using two audiotaped stories that described problem situations typically encountered in the school or home. The children were asked to identify the problem, generate alternative solutions, think of positive and negative consequences for each solution, and offer a personal value supporting their decision. As compared to a no-treatment control group, the children receiving the decision-making training obtained significantly greater scores on four of five dependent measures. Implications for teaching decision-making as a self-management skill are offered.
