We describe a comprehensive program to train emergency shelter staff in effective methods for dealing with youth who have behavioral and emotional problems; assess the degree to which staff implemented the treatment approach; measure the impact of the intervention on shelter-wide incidents such as out-of-control behavior, runaways, and violence against other youth; and examine pre-post changes in staff experiences at the shelter via anonymous surveys. Overall, the short-term shelter staff indicated adequate implementation of the intervention. The rate of youth incidents at the shelter significantly declined from pre to post assessment. Direct-care staff ratings of their satisfaction with their proficiency in behavior management and teaching youth skills increased significantly from pre to post implementation. These findings suggest that it is feasible to deliver an effective staff-training program to improve the behavior management and social skills of youth residing in short-term care facilities within the child welfare system.  相似文献

Contextualizing the role of teachers in social-emotional learning (SEL) in Malawi, we examine how teachers’ comfort with, commitment to, and perceived school culture toward SEL relate to their actual teaching of it. Using surveys from 432 primary school teachers (20–60 years old), we found teacher comfort and supportive school culture were positively related to integration of SEL into classroom instruction, while commitment had no statistically significant relationship with implementation. We explore plausible explanations for these findings by interviewing 42 teachers. Together, our findings highlight the importance of teacher support systems and cultural compatibility of the curriculum for successful SEL implementation.  相似文献

A study was conducted to assess whether individual differences in sexual activity during the past 30 days, in particular penile–vaginal intercourse (PVI; which is associated with measures of relationship quality), are related to the perception of the facial attractiveness of unknown men. Forty-five women reported the frequency of a variety of sexual behaviors and rated the facial attractiveness and friendliness of 24 men. Women who reported more frequent orgasm from masturbation rated men as less friendly. This finding might be reflective of the more anti-social attitude associated with more frequent masturbation. The results also show that women who engaged more frequently in most kinds of sexual behavior, not only PVI, considered unknown men to be less facially attractive. That is, individuals who engage more frequently in a variety of sexual behaviors with their partner perceived unknown men as less attractive and thereby may be less susceptible to the lure of other (or if the only sexual behavior is masturbation, any) men.  相似文献

In a prescient paper Karl Lashley (1951) rejected reflex chaining accounts of the sequencing of behavior and argued instead for a more cognitive account in which behavioral sequences are typically controlled with central plans. An important feature of such plans, according to Lashley, is that they are hierarchical. Lashley offered several sources of evidence for the hierarchical organization for behavioral plans, and others afterward provided more evidence for this hypothesis. We briefly review that evidence here and then shift from a focus on the structure of plans (Lashley's point of concentration) to the processes by which plans are formed in real time. Two principles emerge from the studies we review. One is that plans are not formed from scratch for each successive movement sequence but instead are formed by making whatever changes are needed to distinguish the movement sequence to be performed next from the movement sequence that has just been performed. This plan-modification view is supported by two phenomena discovered in our laboratory: the parameter remapping effect, and the handpath priming effect. The other principle we review is that even single movements appear to be controlled with hierarchically organized plans. At the top level are the starting and goal postures. At the lower level are the intermediate states comprising the transition from the starting posture to the goal posture. The latter principle is supported by another phenomenon discovered in our lab, the end-state comfort effect, and by a computational model of motor planning which accounts for a large number of motor phenomena. Interestingly, the computational model hearkens back to a classical method of generating cartoon animations that relies on the production of keyframes first and the production of interframes (intermediate frames) second.  相似文献

Walking on music     
The present study focuses on the intricate relationship between human body movement and music, in particular on how music may influence the way humans walk. In an experiment, participants were asked to synchronize their walking tempo with the tempo of musical and metronome stimuli. The walking tempo and walking speed were measured. The tempi of the stimuli varied between 50 and 190 beats per minute. The data revealed that people walk faster on music than on metronome stimuli and that walking on music can be modeled as a resonance phenomenon that is related to the perceptual resonance phenomenon as described by Van Noorden and Moelants (Van Noorden, L., & Moelants, D. (1999). Resonance in the perception of musical pulse. Journal of New Music Research, 28, 43-66).  相似文献

The looking behavior of children with pervasive developmental disorder (PDD) and age- and IQ-matched normal control children was studied using infrared oculography. Stimuli varying in complexity and topic were presented to test whether children with PDD have specific abnormalities in looking behavior to complex stimuli and/or to faces. All children showed more and longer fixations on the complex objects than on the simple objects, especially the complex nonsense figure, but group differences were not found. The results show no evidence for specific abnormalities in looking behavior to either faces or to complex stimuli in high functioning children with PDD.  相似文献

This study tested the prediction that the error-related negativity (ERN), a physiological measure of error monitoring, would be enhanced in anxious individuals, particularly in conditions with threatening cues. Participants made gender judgments about faces whose expressions were either happy, angry, or neutral. Replicating prior studies, midline scalp negativities were greater following errors than following correct responses. In addition, state anxiety interacted with facial expression to predict ERN amplitudes. Counter to predictions, participants high in state anxiety displayed smaller ERNs for angry-face blocks and larger ERNs for happy-face blocks, compared to less anxious participants. These results are inconsistent with the simple notion that anxiety enhances error sensitivity globally. Rather, we interpret the findings within an expectancy violation framework, in which anxious participants have altered expectations for success and failure in the context of happy and angry facial cues, with greater ERN amplitudes when expectations are violated.  相似文献
