In a replication of two investigations reported by Looft (1971a, 1971b), 40 second- and sixth-grade male and female students were interviewed concerning their desired and expected vocational aspirations. In contrast to Looft's findings, no significant sex differences were found for either grade level in (a) the number of different (nonoverlapping) vocations nominated or (b) the number of subjects changing initial vocational role choices. When the issue of traditionality of vocational choice (i.e., vocations socially identified with the sex of the subject) was examined, it was found that half of the sixth-grade females interviewed nominated nontraditional vocations (e.g., basketball player, police officer). It was observed further that males in both the second- and sixth-grade samples overwhelmingly nominated traditional vocations. Contrary to Looft's interpretation, the findings suggest that although goals associated with the women's liberation movement (e.g., changes in sex-role expectations) are not demonstrated clearly in the vocational aspirations or expectations of young children, they may be reflected in the aspirations of adolescent females.  相似文献

College students ( n = 197) voted to select a beauty queen from among six photographs equivalent in physical attractiveness, as determined by rankings of 35 students from a separate university. Half the photographs bore a desirable first-name and half were assigned an undesirable first-name. As predicted, firstname had a significant effect on physical attraction: Girls with desirable firstnames received 158 votes to 39 for those with undesirable names. These data were discussed in terms of an additive, rather than an interactive, effect, due to the nature of the task. The strength of these findings was related to the study's ecological validity.  相似文献

A conception of semantic memory structure is presented in which elaboration is considered to vary both between and within items. Pictures and their verbal labels are suggested to activate common abstract memory representations, but these activations will differ in their degree of within-item elaboration. However, pictures and words should show comparable between-item elaboration properties, such as might be revealed by the category-recall relationship and clustering in free recall. Children were presented pictures and words in either a category-recall situation, where between-item elaboration was emphasized, or in a control situation where between-item elaboration was minimized. No differences between pictures and words in either recall or clustering were found in the category-recall task. However, when the same items were presented in the control situation the typical picture superiority effect in free recall was found. The results are interpreted as consistent with a two-factor theory of semantic elaboration, and indicate that these basic properties of memory encoding hold even for young children.  相似文献

It was proposed that people attribute an individual's behavior more to internal factors when that individual's actions are influenced by reward than when those actions are influenced by punishment. Previous research has failed to control for the power of reward versus punishment which, in effect, creates a confounding of behavioral base rates (consensus) with the reward-punishment manipulation. The current research created reward and punishment contingencies that were equal in their base rates for producing a compliant response. In Experiment 1, subjects (n = 63) who produced the base-rate data also made attributions regarding a compliant target person. The results supported the reward-punishment attributional asymmetry hypothesis in that the target person was held more responsible for his actions in the reward than in the punishment conditions. A second experiment (n = 72) provided some attributors with information regarding base rates for compliance and measured perceived base rates for compliance. Knowledge of the base rates for compliance eliminated the reward-punishment attributional asymmetry phenomenon. Subjects not provided with such knowledge erroneously assumed different base rates for reward and punishment and maintained the perception of reward-punishment attributional asymmetry. Using subjects' estimates of base rate for compliance as a covariate eliminated the attributional asymmetry effect. It is suggested that erroneous base-rate assumptions mediate the attributional asymmetry phenomenon.  相似文献

Selective attention to visual and auditory stimuli and reflection-impulsivity were studied in normal and learning-disabled 8- and 12-year-old boys. Multivariate analyses, followed by univariate and paired-comparison tests, indicated that the normal children increased in selective attention efficiency with age to both visual and auditory stimuli. Learning-disabled children increased in selective attention efficiency with age to auditory, but not to visual, stimuli. Both groups increased with age in reflection as measured by Kagan's Matching Familiar Figures Test (MFF). The 8-year-old learning-disabled children were more impulsive than the 8-year-old normals on MFF error scores, but not on MFF latency scores. No difference occurred between the 12-year-old learning-disabled and normal children on either MFF error or MFF latency scores. Correlations between the selective attention scores and MFF error and latency scores were not significant.This research was supported in part by BEH grant G007507227. The authors are indebted to Eleanor McCandless for her assistance in securing the learning-disabled subjects and to James McLeskey and Michael Popkin for their assistance in collecting and analyzing data.  相似文献
