High shyness during early adolescence is associated with impaired peer relationships and risk for psychiatric disorders. Little is known, however, about the relation between shyness and trajectories of brain development over early adolescence. The current study longitudinally examined trajectories of resting‐state functional connectivity (rs‐fc) within four brain networks in 147 adolescents. Subjects underwent functional magnetic resonance imaging at three different time points, at average ages 10.5 (range = 7.8–13.0), 11.7 (range = 9.3–14.1), and 12.9 years (range = 10.1–15.2). Multilevel linear modeling indicated that high shyness was associated with a less steep negative slope of default mode network (DMN) rs‐fc over early adolescence relative to low shyness. Less steep decreases in DMN rs‐fc may relate to increased self‐focus in adolescents with high shyness.  相似文献

The role of parameter variability on retention, parameter transfer, and effector transfer     

Whitacre CA  Shea CH 《Research quarterly for exercise and sport》2002,73(1):47-57

The purpose of this study was to examine the effects of parameter variability on the learning of generalized motor programs (GMP) and movement parameterization. Participants attempted to exert a force pattern that resembled in force and time a waveform displayed on a computer monitor.The analysis suggested that relative timing (a measure of the GMP) performance remained remarkably stable across retention and transfer tests, whereby the structure of the movement remained intact, although the parameter or muscle group (effector) changed during transfer The results also indicated that variable parameter (time) practice did not enhance GMP learning but did degrade the learning parameter that was not varied (force). In addition, parameter specification was substantially less stable than the GMP, with time and force parameter performance deteriorating from the retention to transfer tests. These findings suggest that parameter specification, and not the GMP, is the primary cause of poorer performance in parameter and effector transfer.  相似文献

Tweeting Fast Matters,But Only if I Think About It: Information Updates on Social Media     

Patric R. Spence  Kenneth A. Lachlan  Autumn Edwards  Chad Edwards 《Communication quarterly》2016,64(1):55-71

Social media have emerged as increasingly important sources through which the public seeks information concerning crises or risks. Despite this increased dependence, little is known about the psychological processes associated with perceptions of source credibility or the desire to seek additional information related to the risk. The current study investigates the role of speed of updates in credibility perceptions and information seeking using Twitter. The results do not provide evidence of a direct relationship between update speed and the outcomes under consideration. They do, however, consistently support a mediation model in which cognitive elaboration mediates the relationship between update speed and perceptions of sender competence, goodwill, trustworthiness, and reader (follower/audience/rater/target) desire for additional information. These findings are discussed in terms of their implications and applied use.  相似文献

Perfectionism and depressive symptoms in early adolescence     

Kenneth G. Rice  Brooke A. Leever  Chad A. Noggle  Daniel K. Lapsley 《Psychology in the schools》2007,44(2):139-156

The Adaptive/Maladaptive Perfectionism Scale (AMPS; K.G. Rice & K.J. Preusser, 2002) was developed on samples of 9‐ to 11‐year‐old children. A primary purpose of the current research was to examine whether the AMPS could be useful in studies of adolescents, and in particular, studies of adolescent depression. This study of 145 early adolescents revealed (1) a somewhat different AMPS factor structure than has been evident in studies of younger children; (2) no significant mean differences between boys and girls on perfectionism, although girls were significantly more depressed than boys; (3) a pattern of perfectionism‐depression correlations that differed somewhat between boys and girls; and (4) several interactions of different dimensions of perfectionism in accounting for depression. Results are discussed by addressing differences between children and adolescents in school cultures, physical and psychological changes from childhood to adolescence, and the importance of considering the positive as well as the negative aspects of perfectionism among school‐age children. © 2007 Wiley Periodicals, Inc.
