Transfer of reaction inhibition

A serious challenge to Hull's (1943) theory of reminiscence and intertrial-interval effects is posed by the current contention that reactive inhibition (In) must be task-specific since it does not seem to transfer from one task to another. This notion was examined within the framework of a practice-rest paradigm in which three control groups were given 20 1-min trials on a principal task with intertrial intervals of 0, 5, and 70 sec, respectively, while two experimental groups practiced alternately on the principal task and a secondary task known to produce evidence for I(R). The two secondary tasks varied in their similarities to the principal task. Additional control groups were used to assess the magnitude of habit transfer effects. The total sample consisted of 70 males and 70 females whose modal age was 18 yr. With habit transfer effects controlled, results showed clearly that work effects transferred from the alternate tasks to the main task without regard for differences in similarity. Thus, the task-specificity hypothesis was not supported.     

Empathy and socialization in first and repeat juvenile offenders and normals

The present study examined empathy and socialization in delinquent and non-delinquent juveniles. From 32 first offenders, 16 repeat offenders, and 19 normals who were administered Hogan's empathy scale and the socialization scale of the California Psychological Inventory, groups of 16 subjects matched on age and race were compared. Results indicated that the three groups did not differ on empathy but that each of the three groups differed on socialization. Results are discussed in terms of potentially identifying recidivists and the efficacy of therapist-trained empathy.     

Conceptual encoding and locus of the Stroop effect

Subjects reacted to coloured season and month names by naming the season associated with the print colour of the word, or by naming the season opposite to the one associated with the print colour. Reactions were facilitated in both tasks when the word on the display named the season associated with the colour or was a month belonging to that season. Opposite season naming was not facilitated when the word named the response which the subject made. A comparable effect of print colour was found when subjects reacted to season names by naming the colour associated with the name, or with its opposite. These results suggest that Stroop congruity and interference effects occur during conceptual encoding, and not during response production.     

Evaluation of a continuing computer conference on simulation

A 20-day computer conference was held in preparation for a face-to-face meeting to produce a computer simulation. The conferencing resulted in the generation of seven different models and was excellent preparation for the subsequent meeting. Computer conferencing appears to hold great value for faculty development in a period of reduced faculty mobility.

中国文艺的现代转型——毛泽东文艺思想的奠基性意义

毛泽东文艺思想及其实践确立了大众化的价值品格,实现了文艺由私人活动到公共事业的转变,并高扬了民主和科学的精神,对中国文艺发展具有深刻的现代转型意义.同时,毛泽东实现了民族化对文艺发展的有效规范,使中国文学艺术在实现现代转型的同时依然保留鲜明的民族风格.当然,文学艺术在毛泽东时代发生的深刻转型,并不意味着现代化的完成.
