Human participants searched in a dynamic three-dimensional computer-generated virtual-environment open-field search task for four hidden goal locations arranged in a diamond configuration located in a 5 × 5 matrix of raised bins. Participants were randomly assigned to one of two groups: visual pattern or visual random. All participants experienced 30 trials in which four goal locations maintained the same spatial relations to each other (i.e., a diamond pattern), but this diamond pattern moved to random locations within the 5 × 5 matrix from trial to trial. For participants in the visual pattern group, four locations were marked in a distinct color and arranged in a diamond pattern that moved to a random location independent of the hidden spatial pattern from trial to trial throughout the experimental session. For participants in the visual random group, four random locations were marked with a distinct color and moved to random locations independent from the hidden spatial pattern from trial to trial throughout the experimental session. As a result, the visual cues for the visual pattern group were consistent but not coincident with the hidden spatial pattern, whereas the visual cues for the visual random group were neither consistent nor coincident with the hidden spatial pattern. Results indicated that participants in both groups learned the spatial configuration of goal locations and that the presence of consistent but noncoincident visual cues facilitated the learning of spatial relations among locations.  相似文献

Parental intrusiveness is associated with internalizing problems in healthy children. Given the unique demands that childhood cancer places on parents, it is important to determine whether intrusiveness operates differently in survivors of childhood cancer. The current study tested whether cancer survivorship moderates the relation between maternal directiveness—one aspect of intrusiveness—and children’s internalizing problems. Survivors (7–12 years old) of acute lymphoblastic leukemia (ALL) (n = 25) and their mothers, and healthy controls (n = 22) and their mothers engaged in parent–child interactions. Mothers completed a measure of children’s psychosocial adjustment, and observations of 10-min parent–child interactions were obtained. Cancer survivorship moderated the relation between directiveness and children’s withdrawn/depressed symptoms. Maternal directiveness was associated with increased withdrawn/depressed symptoms for children in the control group. This association was not significant for survivors of ALL. Findings suggest that childhood cancer may alter the context in which children experience maternal directiveness.  相似文献

This article focuses on parents’ role in overweight adolescents’ motivation to diet and successful weight loss. The study employed Self-Determination Theory (SDT) as the theoretical framework (Deci & Ryan, 2000, 2011). Ninety-nine participants (ages 20–30) who had been overweight during adolescence according to their Body Mass Index (BMI mean = 25, SD = 1.6), completed retrospective questionnaires about their motivation to diet and their parents’ behavior in the context of dieting. Findings from a structural equation modeling analysis suggested that participants who viewed their parents’ as more need-supportive demonstrated more autonomous motivation to diet, which, in turn, contributed to their successful weight loss. The findings highlight the importance of parental support of adolescents’ psychological needs in the quality of their motivation to diet. This is an important insight for parents and professionals who aim to encourage more constructive parent involvement in adolescents’ dieting and well-being.  相似文献
