The effects of speech output technology in the learning of graphic symbols

The effects of auditory stimuli in the form of synthetic speech output on the learning of graphic symbols were evaluated. Three adults with severe to profound mental retardation and communication impairments were taught to point to lexigrams when presented with words under two conditions. In the first condition, participants used a voice output communication aid to receive synthetic speech as antecedent and consequent stimuli. In the second condition, with a nonelectronic communications board, participants did not receive synthetic speech. A parallel treatments design was used to evaluate the effects of the synthetic speech output as an added component of the augmentative and alternative communication system. The 3 participants reached criterion when not provided with the auditory stimuli. Although 2 participants also reached criterion when not provided with the auditory stimuli, the addition of auditory stimuli resulted in more efficient learning and a decreased error rate. Maintenance results, however, indicated no differences between conditions. Finding suggest that auditory stimuli in the form of synthetic speech contribute to the efficient acquisition of graphic communication symbols.     

Concurrent phencyclidine and saccharin access: presentation of an alternative reinforcer reduces drug intake.

Six monkeys self-administered orally delivered phencyclidine ("angel dust") and saccharin under concurrent fixed-ratio 16 schedules during daily three-hour sessions. Liquid deliveries were contingent upon lip-contact responses on solenoid-operated drinking spouts. Three saccharin concentrations (0.003%, 0.03% and 0.3%, wt/vol) were tested in a nonsystematic order. For each saccharin concentration, the following series of phencyclidine concentrations (mg/ml) was presented: 0.25, 0.5, 1, 0.25 (retest), 0.125, 0.0625, 0.0312, 0.25 (retest) and 0 (water with stimuli signaling phencyclidine). As the saccharin concentration increased, the number of drug deliveries decreased, and the peaks of the concentration-response functions were shifted to the right. The lowest saccharin concentration (0.003%, wt/vol) maintained responding in excess of phencyclidine levels in only one monkey. The two higher saccharin concentrations maintained behavior far in excess of phencyclidine, but saccharin deliveries decreased in some monkeys as phencyclidine concentration and intake (mg/kg) increased. The time course and patterns of phencyclidine-reinforced responding were also altered when saccharin was concurrently available. The results are discussed in terms of strategies to reduce drug-reinforced behavior, preference between different reinforcers, and measures of reinforcing efficacy.     

教师集体效能理论及其应用

教师集体效能是教师效能在集体水平上的扩展,是教师对其作为一个整体的、能够组织和实施影响学生行为过程的能力知觉和信念,它以知觉到的平均数作为其集体效能测量的整合分数。教师集体效能在学生的学业成就、有效学校的特性以及教师的心理与行为的改变中有着重要的应用。但与教师个体效能相比,教师集体效能的研究在整体上还存在着明显的不足     

工业与组织心理学中的集体效能感

集体效能感是指团体成员对于团体成功地完成特定任务或取得特定水平成就的能力的共同信念,其测量方法主要有自我效能感总和法、个体评估平均法和团体讨论法等三种。在影响效果方面,集体效能感可以有效地预测绩效以及其他一些工作态度和行为变量,但过高的集体效能感也会产生负面作用;在影响因素方面,团体规模和团体间竞争等团体内外部因素均能显著影响集体效能感,并且目标设定训练等干预措施也能显著提高集体效能感。文章最后指出未来的研究有必要加强对新型团队中的集体效能感、集体效能感的动态变化等五方面问题的探讨     

The dimensional structure of the emotional self‐efficacy scale (ESES)

This study aims to investigate the underlying dimensionality of the emotional self‐efficacy scale (ESES) and determine its relationship with measures of ability emotional intelligence (EI) (Mayer–Salovey–Caruso EI Test), trait EI (Trait EI Questionnaire), personality, and cognitive ability. Participants included 822 undergraduate students and 263 graduates already in the workplace. Analyses of the data suggested a multidimensional factor structure for the ESES. The measure was found to correlate with trait EI and showed expected correlations with personality. It did not correlate with ability EI or cognitive ability. These findings are discussed and are interpreted as offering support for the use of the ESES as a reliable measure of emotional self‐efficacy.     

领导权力和地位对下属建言的影响——心理安全感的作用

通过实验研究(研究1、2)和多来源、多时点的实地问卷调查(研究3), 本文发现: 领导权力对下属建言有消极作用, 领导地位对下属建言有积极作用; 领导地位调节领导权力对下属建言的影响, 当领导地位较低时, 领导权力对下属建言的负面作用增强, 反之则不显著; 领导地位对权力的调节作用通过下属心理安全感传递至下属建言行为。这一研究结果有助于阐明组织层级差异(如权力、地位)是如何影响下属建言行为的。     

Team Proactivity as a Linking Mechanism between Team Creative Efficacy,Transformational Leadership,and Risk‐Taking Norms and Team Creative Performance

Despite the growing body of research on creativity in team contexts, very few attempts have been made to explore the team‐level antecedents and the mediating processes of team creative performance on the basis of a theoretical framework. To address this gap, drawing on Paulus and Dzindolet's (2008) group creativity model, this study proposed team creative efficacy, transformational leadership, and risk‐taking norms as antecedents of team creative performance and team proactivity as an intervening mechanism between these relationships. The results of team‐level regression analyses conducted on the leaders and members of 103 Korean work teams showed that team creative efficacy and risk‐taking norms were positively associated with team creative performance. Furthermore, the relationships between team creative efficacy and team creative performance and between risk‐taking norms and team creative performance were mediated by team proactivity. These findings offer new insights regarding the antecedents and the mediator of creative performance in team contexts and important implications for theory and practice.     

Emotional Intelligence and Career Decision‐Making Self‐Efficacy: National and Gender Differences

This study examined the effect of emotional intelligence (EI) on career decision‐making self‐efficacy (CDMSE) in an East Asian context, as well as the moderating roles of gender and country. Data were collected from undergraduate students from China (N = 149) and South Korea (N = 218). The results showed that all 4 factors of EI were positively related to CDMSE. Moreover, while the effects of 3 EI factors on CDMSE were found to be greater among the Chinese students than the South Korean students, no gender differences were detected. By introducing cultural influences, the findings provide important implications for career counseling.     

Community Matters: Intimate Partner Violence Among Rural Young Adults

Drawing on social disorganization theory, the current study examined the extent to which community-level poverty rates and collective efficacy influenced individual reports of intimate partner violence (IPV) perpetration, victimization, and bystander intervention among a sample of 178 young adults (18–24; 67.4 % women) from 16 rural counties across the eastern US who completed an online survey that assessed demographic information, IPV perpetration, victimization, bystander intervention, and collective efficacy. We computed each county’s poverty rate from the 2007–2011 American Community Survey. Generalized estimating equations demonstrated that after controlling for individual-level income status, community-level poverty positively predicted IPV victimization and perpetration for both men and women. Collective efficacy was inversely related to IPV victimization and perpetration for men; however, collective efficacy was unrelated to IPV victimization and perpetration for women. Whereas IPV bystander intervention was positively related to collective efficacy and inversely related to individual-level income status for both men and women, community-level poverty was unrelated to IPV bystander intervention for both men and women. Overall, these findings provide some support for social disorganization theory in explaining IPV among rural young adults, and underscore the importance of multi-level IPV prevention and intervention efforts focused around community-capacity building and enhancement of collective efficacy.
