A high proportion of positive responses was obtained from students who participated in three different types of pre-college orientation programs. Small group approaches consistently elicited more favorable responses than assemblies or large groups. Greater faculty involvement resulted in participants' noting an increased academic emphasis. Participants believed they had benefited in some way from programs which varied considerably as to length, activities, organization, and purposes. 相似文献

This study examined the effect of high and low communication apprehension in conjunction with social and personal settings upon verbal behavior. Step wise multiple discriminant analysis of the data indicated a linear combination of language indices (number of syllables, Noun-Verb/Adjective-Adverb ratio, and phrase repetitions) which discriminated between the high apprehensive-personal setting group and the remaining three groups. Results are discussed relative to theoretical projections and the potential for sensitivity toward communication behavior being operative within the communication apprehension framework. 相似文献

Perceived parental acceptance and female juvenile delinquency 总被引:1,自引:0,他引:1
S E Kroupa 《Adolescence》1988,23(89):171-185
The responses of 62 adolescent females residing at a state training school and 62 high school females on a measure of perceived parental acceptance were compared while statistically controlling for mental age, chronological age, socioeconomic status, social desirability, and family structure. Generally significant (p less than .05) results indicate that incarcerated females viewed their mothers and fathers more negatively than did nonincarcerated females. Slightly more ambivalent results were indicated in the mother-daughter relationship (delinquent girls reported mothers to be more rejecting/neglecting than did nondelinquents, but no significant differences were found between the groups on perceived mother acceptance) than in the father-daughter relationship. Results were discussed in terms of reported parental differences in acceptance-nonacceptance, providing limited support for Ausubel's satellization theory of child development, and the difficulty of inferring causality from retrospective self-report studies using "captive" subjects. 相似文献
