Learning to re-appraise the self during video feedback for social anxiety: Does depth of processing matter?

Video feedback (VF) with cognitive preparation (CP) has been widely integrated into cognitive-behavioral therapy (CBT) protocols for social anxiety disorder (SAD) due to its presumed efficacy in improving negative self-perception. However, previous experimental studies have demonstrated that improvements in negative self-perception via VF + CP do not typically facilitate anxiety reduction during subsequent social interactions - a troubling finding for proponents of cognitive models of social anxiety. We examined whether VF + CP could be optimized to enhance participants’ processing of corrective self-related information through the addition of a post-VF cognitive review (CR). Sixty-eight socially anxious individuals were randomly assigned to perform two public speeches in one of the following conditions: a) exposure alone (EXP); b) CP + VF; and c) CP + VF + CR. Those in the CP + VF + CR condition demonstrated marginally significant reductions in anxiety from speech 1 to speech 2 relative to those who received EXP - an improvement not shown for those in the CP + VF condition. Furthermore, only those who received CP + VF + CR demonstrated significant improvements in self-perception and performance expectations relative to EXP. Decreases in anxiety among participants who received CP + VF + CR relative to EXP were fully mediated by improvements in self-perception. Implications are discussed in the context of cognitive models of social anxiety and mechanisms of exposure-based learning.     

The integration of temporally shifted visual feedback in a synchronization task: The role of perceptual stability in a visuo-proprioceptive conflict situation

The present study examined whether the beneficial role of coherently grouped visual motion structures for performing complex (interlimb) coordination patterns can be generalized to synchronization behavior in a visuo-proprioceptive conflict situation. To achieve this goal, 17 participants had to synchronize a self-moved circle, representing the arm movement, with a visual target signal corresponding to five temporally shifted visual feedback conditions (0%, 25%, 50%, 75%, and 100% of the target cycle duration) in three synchronization modes (in-phase, anti-phase, and intermediate). The results showed that the perception of a newly generated perceptual Gestalt between the visual feedback of the arm and the target signal facilitated the synchronization performance in the preferred in-phase synchronization mode in contrast to the less stable anti-phase and intermediate mode. Our findings suggest that the complexity of the synchronization mode defines to what extent the visual and/or proprioceptive information source affects the synchronization performance in the present unimanual synchronization task.     

Perfectionism, Cognition, and Affect in Response to Performance Failure vs. Success

The current paper describes the results of an experiment in which 200 students who varied in levels of trait perfectionism performed a laboratory task of varying levels of difficulty. Participants received either negative or positive performance feedback, independent of their actual level of performance. Analyses of pre-task and post-task measures of negative and positive affect showed that individuals with high self-oriented perfectionism experienced a general increase in negative affect after performing the task, and self-oriented perfectionists who received negative performance feedback were especially likely to report decreases in positive affect. Additional analyses showed that self-oriented perfectionists who received negative feedback responded with a cognitive orientation characterized by performance dissatisfaction, cognitive rumination, and irrational task importance. In contrast, there were relatively few significant differences involving other-oriented and socially prescribed perfectionism. Collectively, our findings support the view that self-oriented perfectionism is a vulnerability factor involving negative cognitive and affective reactions following failure experiences that reflect poorly on the self.     

The Role of Fidelity and Feedback in the Wraparound Approach

Wraparound approaches are being implemented with children in many mental health systems around the country. Evidence for the effectiveness of the wraparound approach, however, is limited. In addition, the degree to which wraparound interventions adhere to the principles of wraparound has rarely been assessed. We examined the influence of adherence to wraparound principles and outcome feedback within the wraparound approach. Children participating in family team meetings were enrolled in a feedback or no feedback condition. Teams receiving feedback were given a brief report regarding outcome progress four times over a three-month period. In addition, adherence to wraparound principles was assessed in the initial team meeting and examined in relationship to outcome at three months and nine months. Although youth in both feedback and non-feedback groups improved with intervention, there were few differences between the groups based on outcome feedback. Similarly, adherence was uniformly high and did not influence the outcome for individual cases. Although the wraparound approach was helpful for youth in our sample, outcome feedback and adherence to wraparound principles had limited influence on these effects.     

The Effects of Alternate Forms of Performance Feedback on Elementary-Aged Students’ Oral Reading Fluency

Within the context of a brief experimental design, the current study examined the effects of providing two different types of performance feedback, performance feedback on words read correctly (PFWC) and performance feedback on words read incorrectly (PFWI), on the oral reading fluency of six elementary-aged students. For all of the participants, PFWI resulted in higher levels of oral reading fluency than PFWC. In addition, for a majority of the participants, PFWC resulted in lower levels of oral reading errors than PFWI. These results suggest that providing students with performance feedback on the number or words read correctly may enhance the reading fluency of students experiencing reading difficulties. The implications of these results for intervention selection are discussed.     

动态两难对策中信息反馈方式对合作行为的影响

本研究着重探讨了多人动态对策情景中信息反馈方式和群体认同度对合作行为变化的影响。结果表明,集体反馈比个人反馈更能促进被试的合作行为,而群体认同度对合作行为的影响不显著;在集体反馈条件下,合作行为在各轮次问的随机波动较大,但在三个决策阶段问较为稳定;个人反馈条件下,合作行为在各轮次问的随机波动较小,但在三阶段问呈现出不对称的“U”型变化趋势。研究认为,建立在反馈信息基础上的决策学习使合作行为的动态变化具有策略性和适应性。     

反馈效价影响家族相似性类别学习的ERPs研究

采用事件相关电位技术,以大学生为被试,运用被试间实验设计探讨反馈效价（积极反馈,消极反馈）对家族相似性类别学习的影响。研究结果表明,行为结果上相比积极反馈,消极反馈在推理测验中的成绩显著优于积极反馈。脑电结果上,P200,P300和FRN均与家族相似性类别学习中的反馈加工有关;家族相似性类别学习中,积极反馈与消极反馈存在不对称性。相比于无反馈的条件,P300对消极反馈更加的敏感,消极反馈诱发更大的波幅,而P300对于有无积极反馈并不敏感。说明消极反馈条件下,吸引学习者投入更多的注意资源进行认知加工。此外,相比无反馈条件下,消极反馈条件下FRN有更大的激活,说明了消极反馈对被试以后的行为起着更大的调节作用。总之,研究表明相比于积极反馈,消极反馈对家族相似性类别学习更加有效,错误驱动发挥较大作用。     

Comparing forward and backward chaining in teaching Olympic weightlifting

The popularity of Olympic‐style weightlifting in fitness routines is growing, but participating in these exercises with improper technique places lifters at increased risk for injury. Fitness training professionals have developed multiple teaching strategies, but have not subjected these strategies to systematic evaluation, particularly with novice lifters. Two strategies recommended by professional training organizations are akin to forward and backward chaining, which have been shown effective at teaching other novel, complex behaviors. The present study compared these forward‐ and backward‐chaining‐like strategies to teach novice lifters “the clean” and “the snatch,” two Olympic weightlifting movements frequently incorporated into high‐intensity training programs. Participants performed lifts taught with forward chaining more accurately than lifts taught with backward chaining.     

Supervisors’ work-related and nonwork information sharing: Integrating research on information sharing,information seeking,and trust using self-disclosure theory

Although significant scholarly attention has been devoted to understanding subordinates’ information seeking from supervisors, researchers have not paid adequate attention to information sharing by supervisors. Moreover, research on supervisors’ information sharing behavior has focused almost exclusively on work-related information sharing, disregarding supervisors’ sharing of information not related to work (e.g., that related to family). Drawing on self-disclosure theory, we argue that supervisors share both work-related and nonwork information with their subordinates and propose that these two forms of information sharing are conceptually distinct. Furthermore, to unravel the role of supervisors’ nonwork information sharing, we develop an interactive model to test how it may be associated with important employee outcomes. We conducted pilot studies using five samples and, through a sixth study, tested the hypothesized model using a four-wave data collection design. This study makes three major contributions to research and theory. First, it integrates information sharing and information seeking literatures. Second, it underlines the importance of supervisors’ nonwork information sharing in organizations by testing its direct and interactive effects. Third, it contributes to theory by presenting trust as a mechanism that links information disclosure in dyads. Results obtained using structural equation modeling generally supported the proposed model.
