Two experiments were conducted to determine the effect of sex of subject, stated sex linkage of task, and task outcome on causal attributions of an actor's performance. Results from both studies showed that: (1) males evaluate their performance more favorably than do females, despite equivalent objective scores; (2) males claim greater ability than do females following task performance; and (3) females are more prone to use luck to explain performance. The evidence also suggests that the difference between males and females in performance evaluation and self-attribution occurs most strongly in response to failure and on masculine tasks. The results are interpreted in terms of a general expectancy model. 相似文献

To determine whether correspondence in appearance between helper and helped will increase the rate of helping behavior, two types (Hippie and Straight) and two sexes of experimenters approached each of the four corresponding types of subjects and asked to borrow a dime for a telephone call. As predicted, a significantly greater number of persons were willing to lend money to someone who resembled them in appearance. Furthermore, as predicted, his tendency to match on the basis of appearance was stronger for male subjects than for female subjects. It was hypothesized that dress styles, like race, provide a basis for assumptions about other areas of similarity and create a greater willingness to help a similar other. 相似文献

Data on important methodological problems in assessing support networks is presented. Stability (over 1 year) and construct validity were examined in two groups of mothers of preschool children. One group of mothers had children with a physical handicap (n = 25); the other group had normally developing children (n = 44). When their children were 4 years of age and again at 5 years of age, mothers' support networks were assessed with the Pattison Psychosocial Kinship Inventory (a semistructured interview) and a log diary. Results indicated considerable stability in mothers' support networks over the 1-year period. In addition, agreement across methods was fairly high despite marked differences in format, providing evidence for the construct of support networks. Further evidence for construct validity was provided by generally low correlations between support network variables and other measures of social ecology. Findings were roughly similar for both groups of mothers indicating general replicability of findings. 相似文献

We studied visual detection in 150 infants, 1- to 7-days old, by presenting single lines varying in width and location. We found that newborns detected a line only 8′ wide in the central visual field. Peripherally, they appeared to detect lines of 33′, 33′, and 1°6′ at 10°, 20°, and 30°, respectively. Thus, both the central retina and the peripheral retina appear to function at birth. 相似文献

Three ideas are basic to generative theory: (a) Subjects are assumed to attend to the relations among stimuli, extracting the transformations relating pairs of stimuli; (b) the set of abstracted transformations is decomposed or reduced to an elementary set of generators; (c) subjects use the elementary generators as the basis for judging similarity. The purpose of this paper is to illustrate these ideas with an experiment in which subjects were asked to rate the similarity between stimulus pairs. The stimulus materials consisted of the permutations of a 4-item pattern with the properties of a dihedral group which insured the existence of sets of elementary transformations. Three analytic techniques were used to determine the generator set of transformations abstracted by subjects. The first analysis consisted of a monotonic regression between dissimilarity ratings and the number of elementary generators of a given permutation. The residual variance of this monotone regression, suitably normalized, was used as a quantitative goodness-of-fit measure. For the stochastic analysis, cumulative distributions of dissimilarity ratings were obtained for permutations requiring one, two, or three generators. The idea was that permutations requiring fewer generators should be associated with distributions of lower dissimilarity values (higher similarity scores) as compared to permutations predicted to be transformationally more complex. The final analysis, a multidimensional scaling of dissimilarity ratings, converted subjects' ratings into spatial structures to determine whether individual subjects' ratings exhibited the predicted spatial arrangement. The monotone regression and stochastic analyses abstracted similar generator sets for individual subjects, some of which provided perfect fits to the data. Although the scaling analysis yielded similar estimates of generators, for some subjects, transformations with the same number of generators yielded unequal “cognitive” distances resulting in some-what deformed spatial structures for these subjects. It was concluded that the results generally supported a generative model as an approximation to subjects' representations of interstimulus relationships. 相似文献

Children with developmental speech disorders may have additional deficits in speech perception and/or short-term memory. To determine whether these are only transient developmental delays that can accompany the disorder in childhood or persist as part of the speech disorder, adults with a persistent familial speech disorder were tested on speech perception and short-term memory. Nine adults with a persistent familial developmental speech disorder without language impairment were compared with 20 controls on tasks requiring the discrimination of fine acoustic cues for word identification and on measures of verbal and nonverbal short-term memory. Significant group differences were found in the slopes of the discrimination curves for first formant transitions for word identification with stop gaps of 40 and 20 ms with effect sizes of 1.60 and 1.56. Significant group differences also occurred on tests of nonverbal rhythm and tonal memory, and verbal short-term memory with effect sizes of 2.38, 1.56, and 1.73. No group differences occurred in the use of stop gap durations for word identification. Because frequency-based speech perception and short-term verbal and nonverbal memory deficits both persisted into adulthood in the speech-impaired adults, these deficits may be involved in the persistence of speech disorders without language impairment. 相似文献

Six personality factors, including five resembling the human Big Five, had previously been identified in a separate group of zoo-housed chimpanzees. Comparability of chimpanzee personality factor structure was examined in two highly contrasting habitats: zoos and a large African sanctuary. Questionnaires for the zoo chimpanzees were in English, while most for the chimpanzees in the sanctuary were in French. Differences between the two settings were sufficiently extensive to make them analogous to cross-national human personality studies. Internal consistencies for five of the six factors did not differ between the two samples. The patterns of correlations between the unit-weighted factors were also similar for the two samples. Data from these two samples were pooled and factor analyzed. The resulting factor structure was then rotated to the factor structure described in the original study of chimpanzee personality. Dominance, Extraversion, Dependability, and Agreeableness had high congruences. Emotionality and Openness did not, but the items that had the highest loadings were consistent with the factors' definitions. Finally, sex and age effects for all factors generalized across habitats. 相似文献

This study assessed the nature of the person-team fit relationships for extraversion on members' attraction toward their teams. Unlike most studies of personality-based fit, which emphasize similarity, we predicted that complementary fit on extraversion (i.e., high individual-low team or low individual-high team levels) would result in greater attraction to the team. Data from two independent samples of intact project teams were analyzed, including 324 MBA students comprising 64 case analysis teams and 217 members of 26 manufacturing teams. Using polynomial regression analysis and three-dimensional surface plots, our results supported the predicted relationship. In addition, the data indicated that individuals who were more attracted to their teams were also better performers, as judged by their peers and supervisors. 相似文献

While the prevalence of complicated grief has been demonstrated to be elevated in survivors of suicide, the association between complicated grief and suicidal ideation among adult survivors of suicide has not been explored. The purpose of the present study is to examine the association between complicated grief and suicidal ideation in suicide survivors. The Inventory of Complicated Grief and the Beck Depression Inventory were administered to 60 adult survivors within 1 month of a death by suicide of a family member or significant other. Complicated grief was associated with a 9.68 (CI: 1.036, 90.417) times greater likelihood of suicidal ideation after controlling for depression, suggesting that syndromal complicated grief heightens vulnerability to suicidal ideation. Clinicians may provide more comprehensive assessments by recognizing the possibility of suicidal ideation in those with complicated grief. 相似文献
