Do infants see emotional expressions in static faces? 总被引:2,自引:0,他引:2
To determine whether young infants discriminate photographs of different emotions on an affect-relevant basis or on the basis of isolated features unrelated to emotion, groups of 17-, 23-, and 29-week-olds were habituated to slides of 8 women posing either Toothy Angry, Nontoothy Angry, or Nontoothy Smiling facial expressions and were then shown 2 new women in the familiarized expression and in a novel Toothy Smiling expression. At all 3 ages, recovery to the novel Toothy Smiling faces occurred only after habituation to Nontoothy faces (whether smiling or angry), not after habituation to Toothy Angry faces, indicating that infants had been responsive to nonspecific features of the photographs (presence or absence of bared teeth) rather than to affectively relevant configurations of features. In a second experiment, 2 older age groups (35 and 41 weeks) also proved to be insensitive to affect-related aspects of still faces, though more so for angry than for happy expressions. It is suggested that the young infant's difficulty in extracting emotional information from static stimuli may be attributable to the absence of the critical invariants (dynamic, multimodally specified) that characterize naturalistic expressions of emotion. 相似文献

A group of 633 college students at a large midwestern public university was asked fifteen questions pertaining to personal long-term course planning. The results indicated that only 48% of the students sketched out a tentative listing of at least two courses per term for one or more subsequent semesters when first planning courses for the current semester. Long-range planning was positively correlated with the number of years students had already spent in college and with students' perception of the following factors: course planning utility, degree of certainty about pursuing one's current first choice of career, and degree of commitment in using college coursework as a means of achieving a career goal (all p < 0.001). Long-range planning was negatively correlated with the anticipation of a possible change in academic interests. Such planning was not significantly correlated with students' entrance examination aptitude scores or grade point averages. Thus, students' long-range planning of courses was associated more strongly with career commitment than with recent academic performance or aptitude. 相似文献

This study evaluated the emotional and marital adjustment of hearing parents of hearing-impaired youths. Participants included mothers and fathers of hearing-impaired youths and mothers and fathers of hearing youths. In contrast with expectations based on clinical impressions reported in the literature, parents of hearing-impaired youths reported less symptomatology than did parents of hearing youths, and there were no differences in the marital satisfaction of parents in intact families. Moreover, parental adjustment was not associated with the duration of time since the child was diagnosed as hearing impaired. In addition, hierarchical multiple regression analyses revealed that family cohesion was associated with low maternal symptomatology and high marital satisfaction for both spouses. For mothers, low symptomatology was associated with low stress and female gender of child; high marital satisfaction also was linked with a less severe degree of hearing loss in the youth. 相似文献

To determine if neuropsychological deficits, known to precede alcohol use in those genetically predisposed to alcoholism, were present in an alcoholic population, 25 male alcoholics (mean age 41.1) were interviewed concerning alcohol usage, educational difficulties in elementary school, and family history of alcoholism. Using a regression table, discrepancies between current IQ on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) (Wechsler, 1981) and achievement on the Woodcock-Johnson Psycho-Educational Battery (WJB) (Woodcock & Johnson, 1977) were calculated to determine present learning status. Forty percent of the alcoholics were found to have had special education, remedial services, or repeated grade failure concurrent with a familial history of alcoholism and current discrepancies indicative of learning disability. There were no significant differences on intelligence, years of drinking, or mean grades completed in school between this group and the rest of the subjects who did not receive services in school. Conclusions were that childhood learning disorders may be related to the development of alcoholism, particularly when alcoholism is in the family, and that special educators have a role to play in the prevention and treatment of alcoholism. 相似文献

Collaboration between subject matter specialists, computer programmers and educational technologists has resulted in the production of POPTRAN, a computer assisted learning package designed to teach the basic concepts of population studies. Its evaluation in developing countries, with both naive and specialist users, and subsequent revision, has produced a package of both academic quality and teaching effectiveness. 相似文献
