The aim of this study was to investigate the coupling of the biological system of infant sleep and the social system of mother-infant synchrony. Before birth and shortly after birth the systems appear to be connected, but it is unclear whether this remains the case over time. This study therefore examined whether infant sleep measured at 6 weeks and 5 months could predict mother-infant gaze synchrony after a social challenge at 5 months (N=84). Infant sleep was measured in terms of sleep bout duration, which normally increases during this period. Gaze was defined in terms of looking at each other's head simultaneously, known as gaze synchrony, or looking elsewhere. Results showed that infant sleep could predict the temporal dynamics of the mother-infant interaction in terms of flexibility of gaze pattern shifts. The larger the increase in sleep bout duration over age, the more flexible the interaction appeared to be. Maternal Age, type of feeding and change of feeding appeared to function as confounding variables in this relation. Infant sleep could not predict percentage of synchrony (central tendency measure) or the average sequence length of gaze patterns (temporal dynamic measure). 相似文献

An atypical Cortisol Awakening Response (CAR) has been related to adult anxiety and depression, but little is known about the association between long-term atypical CAR and adolescent anxiety and depression. This study aimed to longitudinally identify subgroups of adolescents with distinct levels of CAR (i.e., adolescents with and without persistent atypical CAR) and to examine their development of anxiety and depressive symptoms over 3 successive years. A community sample of 184 Dutch adolescents (M age?=?14.99 at T1, 57 % boys) completed annual salivary cortisol assessments at home at time of awakening, and 30 and 60 min post-awakening (i.e., CAR) for 3 successive years. Adolescents also reported annually on their anxiety and depressive disorder symptoms. Latent Class Growth Analysis suggested two subgroups of adolescents with respect to CAR: a “low” group with stable low levels of AUCg (Area Under the Curve with respect to the ground) over time and a “high” group with high and increasing levels of AUCg over time. Controlling for sex, the high and low CAR groups significantly differed in depressive symptoms only, but none of the anxiety disorder symptoms. More specifically, adolescents in the high CAR group showed significantly higher mean levels of depressive symptoms over time compared to adolescents in the low CAR group. These results suggest that persistent heightened CAR is a more consistent, yet modest, correlate of adolescent depressive symptoms than anxiety disorder symptoms. 相似文献

In this study, mental rotation performance was assessed in both an object-based task, human figures and letters as stimuli, and in an egocentric-based task, a human figure as a stimulus, in 60 older persons between 60 and 71 years old (30 women, 30 men). Additionally all participants completed three motor tests measuring balance and mobility. The results show that the reaction time was slower for letters than for both human figure tasks and the mental rotation speed was faster over all for egocentric mental rotation tasks. Gender differences were found in the accuracy measurement, favoring males, and were independent of stimulus type, kind of transformation, and angular disparity. Furthermore, a regression analysis showed that the accuracy rate for object-based transformations with body stimuli could be predicted by gender and balance ability. This study showed that the mental rotation performance in older adults depends on stimulus type, kind of transformation, and gender and that performance partially relates to motor ability. 相似文献

The present study sought to investigate the influence of self-activation on body and weight satisfaction in restrained and unrestrained eaters, after exposure to thin-ideal images. Restrained eaters (n = 39) and unrestrained eaters (n = 40) were randomly assigned to a self-activation manipulation versus a control manipulation. After the manipulation, all participants were exposed to eight thin-ideal images. Measures of state body and weight satisfaction and of social comparison tendencies were assessed throughout the experiment. Self-activated restrained eaters showed a significant decrease in body and weight satisfaction after exposure to thin-ideal images, compared to restrained eaters who were not self-activated. In unrestrained eaters, the self-activation manipulation did not have any effect on body or weight dissatisfaction. In conclusion, exposure to fashion models only had a negative influence on women's self-evaluations when two conditions were met: (1) the participant was ‘self-activated’ and (2) the participant classified as a restrained eater. 相似文献

The performance on the Stroop Color-Word Interference Test of 36 boys with Attention Deficit Hyperactivity Disorder (ADHD) was compared with performances of a matched control sample. The control group outperformed their counterparts on the control and interference conditions of the Stroop test, suggesting ADHD-specific executive and reading deficits. When individuals with both ADHD and reading disorders were excluded from the analysis, the authors found a significant difference between the ADHD group and the control group on the color-word test, indicating that poor reading skills may produce false negatives on the Stroop test. However, fast and slow readers with ADHD did not perform differently from each other on the color-word test. The authors postulated the existence of two different causes of reading problems: phonological deficits and attentional deficits. 相似文献

This article reviews the progress made by the field in its short history and attempts to look at developments which seem likely to occur as the field matures. Recommendations are made for training of health psychologists in the future and a plea is made for international standardisation of health psychology training programmes at the Ph.D. level which incorporate research and clinical training. Health psychologists are further encouraged to take a more active public and political role in order to provide needed visibility for their work. 相似文献

This study contributes to research on assessment centers' (AC) external construct-related validity by investigating a potential moderator of the relationship between personality and AC dimension ratings. On the basis of recent insights in person-situation contingencies we hypothesized that individual differences in people's perception of situational demands moderate the relationship between personality and conceptually related AC dimension ratings. The hypotheses were tested with 108 individuals in two leaderless group discussion exercises. Results confirmed the hypotheses for two of the three traits (i.e., Agreeableness and Conscientiousness). In particular, people high on these traits who identified the situational demands received higher AC dimension ratings. People high on these traits who did not identify the situational demands received lower AC dimension ratings. 相似文献
