Exposed eye area (EEA) was measured in photographs of Indian adults who modeled six emotions--happiness, sadness, fear, anger, surprise, and disgust--as well as a neutral expression. The data were analyzed with a 2 x 6 (Eyes x Emotions) factorial analysis of covariance (ANCOVA). EEA for neutral expression was used as the covariate measure. The EEAs of the two eyes did not differ significantly during the expression of emotion. The EEAs for fear and surprise were significantly larger, and the EEA for disgust was significantly smaller than those for either other emotions or neutral expression. 相似文献

Associations of two different response sets on the Infrequent Response Index of the Strong Interest Inventory (SII) were examined. In one, participants responded to each item randomly; in the other, participants deliberately misrepresented their responses. The finding of scores higher than those proposed in the SII manual for the Infrequent Response Index suggests an alternative interpretation of this critical index. 相似文献

This study examined the career aspirations of pregnant teens enrolled in a program designed to minimize their chances of dropping out of high school. The teens completed a demographic data form that included questions on their career aspirations. The data were coded by Holland type using the Dictionary of Holland Occupational Codes. Trends were discussed in light of the future labor market and critical need for career counseling for this at-risk population. 相似文献

A recent paper by Kail (1988) in this journal appears to contain a significant error in the data analysis. The "goodness-of-fit" coefficients reported which suggest that overall about 94% of the variance can be accounted for by the model seem to be a substantial overestimation as a result of inappropriate procedures for statistical modeling. Using the data made available to us by Kail, we have reanalyzed these results. The corrected values range from 0.9 to 92.1% for the individual tasks with an overall average between 40 and 60%. We suggest that the support for the original conclusions is considerably weaker than reported. 相似文献

In an article in the Journal of Applied Psychology, Vecchio (1990) purported to test cognitive resource theory (Fiedler, 1986; Fiedler & Garcia, 1987). We present evidence that Vecchio's article seriously misrepresented previous work on cognitive resource theory and also contained several flaws in methodology that call into question his conclusions regarding the validity of cognitive resource theory. 相似文献

The intent of this study is to apply a cross-level design to examine the influence of contextual factors upon individuals' performance. The results support the hypothesis that peer group characteristics predict individual performance beyond individual characteristics. The implications for using a cross-level approach to study the effects of contextual variables on individual-level phenomena are discussed. 相似文献

A scenario study was performed to investigate whether people in the street would be less likely to respond positively to a stranger's request for a small favor if the stranger wore a T-shirt bearing a progay slogan. One hundred and eighteen female and 112 male participants were each presented with six scenarios, all of which asked them to imagine being approached by a person requesting change for a banknote. The dependent variable in the study was the participant's judgment, on a 7-point scale, of how likely he or she would be to help. Five of the scenarios were included as distractors. In the critical scenario, the requester was described as wearing a plain T-shirt or one with either a progay or a control slogan printed on it. The male participants in the progay condition showed a significantly lower level of help than those in either of the control groups. The antigay pattern, however, was not obtained in the responses of the female participants. The results are discussed with reference to other findings in the literature, and their implications for people's responses to progay persons in everyday life are considered. 相似文献
