Associations among sexual victimization and the psychosocial functioning of African American and Latina pregnant and parenting adolescents were examined. Forty-seven (17.7%) of the 265 participants reported histories of sexual victimization, most of which was unwanted sexual intercourse. The victimized adolescents reported higher levels of depression, anxiety, and life stress and, although the two groups reported no differences in their levels of social support, support was found to be differentially related to depression and anxiety in the two groups. In particular, victims derived benefits from social support at low levels of stress, but social support provided no protection against depression and anxiety at average or high levels of stress. For nonvictims, social support provided no benefits at low levels of stress, but protected against depression and anxiety at moderate levels of stress and against depression at high levels of stress. Implications of these findings for research, theory, and intervention are discussed. 相似文献

In temporal bisection, the subject is required to compare the similarity of a probe duration with two referent durations. Two bisection experiments with human subjects are reported in which performance under three referent conditions was compared. In two of the conditions, no-referent and fixed-referent, the referent pair was constant throughout the session and was varied between sessions. In the noreferent condition, samples of the referents were presented at the beginning of a block of trials, but not on the probe trials. In contrast, in the fixed-referent condition, the referent pair was presented on each probe trial. In the third referent condition, roving-referent, the referent pair was also presented on each probe trial, but the values of the pair varied during a session rather than between sessions. The pseudologistic Model (PLM; Killeen, Fetterman, & Bizo, 1997) provided an excellent account of the data from all referent conditions and indicated that (1) the scalar variability was located in the perception of the probe and was independent of the structure of the bisection task, (2) the role of the referents was to set the criterion, (3) the probe was compared with the criterion rather than with the referents, and (4) the comparison of the probe with the criterion occurred even when trial referents were available. 相似文献

Findings on both attractiveness and memory for faces suggest that people should perceive more similarity among attractive
than among unattractive faces. A multidimensional scaling approach was used to test this hypothesis in two studies. In Study
1, we derived a psychological face space from similarity ratings of attractive and unattractive Caucasian female faces. In
Study 2, we derived a face space for attractive and unattractive male faces of Caucasians and non-Caucasians. Both studies
confirm that attractive faces are indeed more tightly clustered than unattractive faces in people’s psychological face spaces.
These studies provide direct and original support for theoretical assumptions previously made in the face space and face memory
literatures. 相似文献

The presence of indebtedness is known to be a risk factor that can trigger stressed persons to contemplate suicide. This study compares the profiles of suicides with and without debt problems based on 2002 Coroner's Court death files. The category of men aged 25–39 has seen a 70% increase in suicide rate since 1997, and the number using carbon monoxide poisoning has increased from 1% of the total deaths in 1997 to about 26% of the total deaths in 2002. Suicides associated with debt problems seem to involve fewer mental and physical problems with formal job attachment than do suicides without debt problems. Gambling is a significant contributing factor to unmanageable indebtedness. 相似文献

BACKGROUND/HYPOTHESIS: The degree of attention directed to a stimulus and the presence of anisometric representations can alter the perception of the magnitude of a stimulus. We wanted to learn if normal right-handed subjects' estimates of distance traveled are influenced by the right-left direction or hemispace of movements. METHODS: We had blindfolded participants estimate the distance their arm was moved in a rightward or leftward direction, in right and left hemispace. Since we wanted subjects to estimate the distance traveled rather than compute the distance between the start and finish points, the subjects' arms were passively moved in sinusoidal trajectories at a constant speed. RESULTS: Subjects estimated leftward movements as longer than rightward movements, but there was no effect of hemispace. COMMENTS/CONCLUSIONS: People often attend more to novel than routine conditions and therefore participants might have overestimated the distance associated with leftward versus rightward movement because right-handed people more frequently move their right hand in a rightward direction and learn to read and write using rightward movements. Thus, leftward movements might be more novel and more attended than rightward movements and this enhanced directional attention might have influenced estimates of magnitude (distance). 相似文献

Other-race individuals are remembered more poorly and receive less holistic/configural processing than same-race individuals, at least when faces are novel. Here, we examine the amelioration of these effects with familiarity, using distinctiveness-matched Caucasian and Asian stimulus sets. We confirmed a cross-race deficit for upright faces following a single encoding trial, which disappeared rapidly with practice on a small set of other-race 'friends' and did not re-emerge when perceptual processing was put under stress (presentation in the periphery). We also examined holistic/configural processing for familiarised faces using the peripheral inversion effect (McKone, 2004 Journal of Experimental Psychology: Learning, Memory, and Cognition 30 181 - 197). A test for faces and nonface objects (dogs) confirmed the validity of this technique as providing a direct measure of holistic processing; we then showed that, after 1 h of training, holistic processing was as strong for other-race as same-race faces. We conclude that practice with other-race individuals can rapidly engage normal face-processing mechanisms. 相似文献

Developing mechanisms for predicting human action is a critical task of early conceptual development. Three studies examined whether 4-year-old children (N = 149) use social allegiances to predict behavior, by testing whether they expect the experiences of social partners to influence individual action. After being exposed to a conflict between two individuals from different novel social categories, children reliably predicted that another member of one category would withhold friendship from the contrasting category (Studies 1 and 2) and direct harmful actions toward the contrasting category (Study 3). Children did so even when the initial conflict had no direct implications for the other category members, and even when they knew that the two social categories had a positive relationship in the past. These data show that young children view social categories as marking people who are obligated to one another, and thus use the experiences of allegiance partners to predict how individuals will behave.
