The current study examined the contributions of maternal and peer support to depressive symptoms in early to mid-adolescence
and variation in these contributions across age, gender, and race. Five waves of data on maternal support, peer support, and
depressive symptoms were collected on rural youth (N = 3,444) at 6 month intervals. Multilevel modeling was used to evaluate within and between-person effects of maternal and
peer support on depressive symptoms. Within-person effects of peer support did not vary by age, gender, or race. At the between-person
level, peer support predicted levels of depressive symptoms at age 12, but this effect became nonsignificant after controlling
for maternal support. Within-person effects of maternal support did not vary with age but were qualified by gender and race.
Between-person effects of maternal support on depressive symptom levels at age 12 and slopes varied across race and gender,
respectively. Findings highlight the robustness of the protective effects of maternal and peer support during adolescence
among girls and white youth. 相似文献

ABSTRACTExposure to negative life stress has been associated with difficulty retrieving memories for specific autobiographical events, with important consequences for the emergence of emotional disorders. We examined whether social support can protect against the effects of negative events on memory specificity. University students (N?=?143) were assigned to groups based on whether or not they experienced a negative stressor, operationalised as whether or not their recent exam performance was in line with their expectations. After receiving their exam results (T1), and one month later (T2), participants completed measures of memory specificity, their attitudes towards themselves and the occurrence of other stress-related events. Participants also completed a general measure of perceived social support from friends, family, and significant others, and an equivalent measure for social support related to performance. For participants who experienced an exam-related stressor, reduced performance-specific social support from friends was associated with reduced memory specificity at T2, even when accounting for T1 memory specificity, individual differences in attitudes towards self, the experience of additional stressors, and gender. No such relation was present for participants who did not experience a stressor. These findings provide new understanding of the influence of social variables on autobiographical memory specificity. 相似文献

ABSTRACT The purpose of this research was to investigate similarities and differences in general, artistic, and scientific creativity between engineering versus music students, as 2 groups respectively representing scientific and artistic domains. One hundred music and 105 engineering students from a large, Northeastern university completed measures of general creativity, music creativity, engineering creativity, and a demographic questionnaire. Results indicated that musicians scored higher in general and artistic creativity, with no significant differences in scientific creativity. Participants had higher levels of creativity, compared with normative data from previous studies. Gender, age, and specialization within major yielded no significant differences. Implications for creativity measures are discussed, including cognitive risk tolerance. 相似文献

This article presents an assessment of the relative influences of time spent participating in organized sports and informal sports during childhood with respect to the development of general creativity. In this study, 99 upper-division undergraduate and graduate students completed a comprehensive childhood leisure activities questionnaire and the Abbreviated Torrance Test for Adults. According to the results of the joint generalized least-squares regression analysis, hours spent in organized sport settings was negatively related to creativity as an adult; time spent in unstructured sport settings was found to be positively related to adult creativity. The findings also point to the importance of balancing participation across organized and unstructured settings. The most creative individuals in the sample were those who spent roughly half of their sport participation time in each setting, as opposed to individuals with below-average creativity, who spent upwards of 3/4 of their sport participation time in organized settings. Therefore, fostering creative development through sport may not require a dramatic reorientation from current youth sport development models, but only a shift toward a more balanced distribution of time spent playing in both organized and unstructured settings. Future experiments are needed to test this relationship. 相似文献

Bodily perspective taking goes social: the role of personal,interpersonal, and intercultural factors

Mentally placing the self in the physical position of another person might engage social perspective taking because participants have to match their own position with that of another. We investigated the influence of personal (sex), interpersonal (siblings, parental marital status), and cultural (individualistic, collectivistic) factors on individuals' abilities to mentally take the position of front‐facing and back‐facing figures in an online study (369 participants). Replicating findings from laboratory studies responses were slower for front‐facing than back‐facing figures. Having siblings, parents' marital status, and cultural background influenced task performance in theoretically predictable ways. The present perspective‐taking task is a promising experimental paradigm to assess social perspective taking and one that is free from the response biases inherent in self‐report. 相似文献

Immigrants' sense of self can be derived both from being members of their ethnic in‐group and their country of residence. We examined how the ways in which immigrant adolescents integrate these self‐views in relation to academic success in German schools. Students describe themselves at school and when with family. Using a standardized literacy performance test, analyses revealed that immigrants whose school‐related self‐view did not include Germany were less successful: Students who described their self as including both aspects of their ethnic group and Germany, and students who saw themselves predominantly as German, outperformed students with purely ethnic school‐related selves. As expected, though, an ethnic family‐related self‐view did not have a negative impact on scholastic achievements. 相似文献

The authors studied the development of postural adjustments associated with the initiation of gait in children by using kinematic and electromyographic (EMG) analysis. Participants (N = 28) included infants with 1-4 and 9-17 months of walking experience, children 4-5 years of age, and adults. Anticipatory postural adjustments (APA) were present in the youngest age groups, including a clear anticipatory lateral tilt of the pelvis and the stance leg, which enabled the child to unload the opposite leg shortly before its swing phase. An anticipatory activation of the hip abductor of the leg in stance phase prior to heel-off was found, suggesting pelvis stabilization. APA did not appear consistently until 4-5 years of age. A decrease in segmental oscillations occurred across the ages, indicating better control of intersegmental coordination in the frontal and sagittal planes during the postural phase of gait initiation. Young walkers presented APA involving movements of both the upper and the lower parts of the body, whereas, like adults, 4- to 5-year-olds were able to laterally shift only the pelvis and the stance leg. The oldest children and the adults also showed lower activation levels of hip and knee muscles but higher activation at the ankle level. Those kinematic and EMG results taken together suggest a clear developmental sequence from an en bloc operation of the body through an articulated operation with maturation, walking experience, or both. 相似文献

The role played by reflex pathways in the production of movement has been a significant issue for motor control theorists interested in a wide variety of motor behaviors. From studies of locomotion and chewing, it appears that gains in reflex pathways can be altered so that activity in these pathways does not produce destabilizing responses during movement. In speech production, recent experimental evidence has been interpreted to suggest that autogenetic lip reflexes (perioral reflexes) are suppressed during sustained phonation or speech production. The present study was conducted to assess the effects of phonation, direction of movement, and ongoing speech production on reflex responses of lip muscles. The present results suggest, in contrast to earlier work, that this reflex pathway is not suppressed during phonation or speech. However, the response may appear to be suppressed or absent because the amplitude of the observed response depends upon the activation levels of the various muscles of the lower lip and, therefore, indirectly on the nature of the gesture the subject is instructed to produce. 相似文献
