The influence of adolescents' autonomy and relatedness to parents on romantic relationships was examined longitudinally over 5 years in 76 middle-class African American late adolescents (mean age = 18.43 years). Relatedness to parents in early adolescence led to longer duration and more supportive romantic relationships in late adolescence, but longer duration was concurrently associated with more negative romantic relationships. Cluster analyses yielded 3 profiles of early adolescent autonomy and relatedness; early adolescents who were high in relatedness and low in autonomy to parents in early adolescence reported longer duration romantic relationships in late adolescence than did adolescents who were moderate or high in relatedness and high in autonomy. The implications for romantic development in African American middle-class youth are discussed.  相似文献

The major aim of this study was to examine the longitudinal association between adolescent smoking involvement and self-reported psychological and physical outcomes in young adulthood. Participants included 333 African Americans and 329 Puerto Ricans who were surveyed in 1990 in their New York City schools and interviewed in 1995 and 2000-2001, primarily in their homes. The psychological outcomes included ego integration, symptoms of depression, anxiety, and interpersonal difficulty. The physical health measures included a general health rating, number of illnesses, and symptoms of ill health. Also, three scales measured problems due to alcohol, marijuana, and other illicit drug use. Smoking involvement varied by age, sex, and ethnicity but not by socioeconomic status nor by late adolescent parental status. Analysis showed that the relationships between adolescent smoking involvement and psychological and physical health problems in young adulthood remained significant even with control on demographic factors, earlier levels of the outcome variables, and marijuana use. The relationships between smoking behavior and problems with alcohol, marijuana and other illicit drug use were particularly strong. Thus, adolescent smoking seems to have a wide range of clinical implications for young adulthood.  相似文献

Dion, Berscheid, and Walster (1972), in their seminal article, labeled the attribution of positive characteristics to attractive people the "beauty-is-good" stereotype. The stereotyping literature since then provides extensive evidence for the differential judgment and treatment of attractive versus unattractive people, but does not indicate whether it is an advantage to be attractive or a disadvantage to be unattractive. Two studies investigated the direction of attractiveness stereotyping by comparing judgments of positive and negative attributes for medium vs. low and medium vs. high attractive faces. Taken together, results for adults (Experiment 1) and children (Experiment 2) suggest that most often, unattractiveness is a disadvantage, consistent with negativity bias (e.g., Rozin & Royzman, 2001) but contrary to the "beauty-is-good" aphorism.  相似文献

Moving visual stimuli have been shown to reduce unilateral neglect (ULN), however, the mechanisms underlying these effects remain poorly understood. This study compared lateralised and non-lateralised moving visual stimuli to investigate whether the spatial characteristics or general alerting properties of moving visual stimuli are responsible for reducing neglect. Post-stroke left neglect patients as well as healthy and patient control subjects were tested on a computerised line bisection task under six visual stimulus conditions. The key finding was that, relative to the no stimulus condition, leftward moving and left-sided moving visual stimuli shifted neglect patients' bisection errors leftward while the non-lateralised random moving visual stimuli did not reduce neglect patients' rightward bisection errors. The results provide evidence that spatial characteristics rather than general alerting properties of moving visual stimuli reduce rightward bisection errors in ULN. Moreover, the pattern of findings strongly supports the notion that moving visual stimuli reduce neglect by capturing attention and drawing it to a spatial location rather than by activating the attentional system via superior collicular neurons.  相似文献

This paper reports three studies in which stronger orienting to perceived eye gaze direction was revealed when observers viewed faces showing fearful or angry, compared with happy or neutral, emotional expressions. Gaze-related spatial cueing effects to laterally presented fearful faces and centrally presented angry faces were also modulated by the anxiety level of participants, with high- but not low-state anxious individuals revealing enhanced shifts of attention. In contrast, both high- and low-state anxious individuals demonstrated enhanced orienting to averted gaze when viewing laterally presented angry faces. These results provide novel evidence for the rapid integration of facial expression and gaze direction information, and for the regulation of gaze-cued attention by both the emotion conveyed in the perceived face and the degree of anxiety experienced by the observer.  相似文献
