Prior research has shown that muscle tics can be suppressed by the performance of a competing response contingent on the occurrence of the muscle tics. In an effort to determine whether the topography of the competing response was important to the muscle tic suppressing effects of contingent competing response practice, we evaluated the effects of a competing response that was topographically dissimilar to the muscle tic. Three subjects engaged in dissimilar competing responses contingent on the occurrence of a muscle tic; 2 of these subjects subsequently engaged in similar competing response practice. The results showed a decrease in objective measures of muscle tic frequency with the introduction of dissimilar competing response practice for each subject; subsequent exposure to similar competing response practice for 2 subjects resulted in no additional decrement in the level of muscle tics. These results suggest that the topography of the competing response may not be crucial for the suppression of muscle tics. Discrepancies between the objective measures of muscle tics and self-recorded measures are noted and discussed. 相似文献

Two pigeons were trained to peck whichever of eight keys displayed a white field (SD). The other seven keys displayed a white "X" on a black background (S delta). Each peck to SD produced three-second access to grain, a three-second intertrial interval (ITI), and the next trial. Pecks to S delta produced a three-second timeout (TO) and the same trial. During later sessions the key displaying SD changed every t seconds (t = 3, 2, 1, .5, and .25 sec), requiring the birds to track the position of the SD. Pecks on a ninth key increased t. Several sessions employed novel stimuli to ascertain the controlling stimulus dimensions. Both birds made few errors acquiring the original discrimination. During the tracking sessions, both birds made few errors when t = .5 sec. Only one reliably lengthened t. Data from sessions with novel stimuli indicate that color and form were important aspects of SD and S delta respectively; movement contributed to the final performance. 相似文献

为了考察在中国背景下,家长参与在家庭社会经济地位与高中生学习品质之间的中介作用,以及师生关系对上述中介效应的调节。以东部某省13442名高中二年级学生为被试,采用家长的受教育程度、家长的职业以及家庭拥有物三个指标测量家庭社会经济地位。采用家长参与子女学习和家长参与子女日常生活两个指标测试家长参与度。采用学习兴趣、学习自信心、学习策略、自主学习能力、学习习惯五个分指标测量学生的学习品质。采用师生关系量表测量师生关系。结果表明:(1)家庭社会经济地位可以正向显著预测高中生的学习品质;(2)家长参与在家庭社会经济地位与高中生学习品质之间起完全中介作用;(3)家庭社会经济地位经由家长参与影响高中生学习品质的中介作用受到师生关系的调节;(4)因家庭社会经济地位不同造成的学生学习品质的差异,在一定程度上会受到师生关系的弥补作用。 相似文献

Increased use of online communication in everyday life presents a growing need to understand how people are influenced by others in such settings. In this study, online comments established social norms that directly influenced readers' expressions of prejudice both consciously and unconsciously. Participants read an online article and were then exposed to antiprejudiced or prejudiced comments allegedly posted by other users. Results revealed that exposure to prejudiced (relative to antiprejudiced) comments influenced respondents to post more prejudiced comments themselves. In addition, these effects generalized to participants' unconscious and conscious attitudes toward the target group once offline. These findings suggest that simple exposure to social information can impact our attitudes and behavior, suggesting potential avenues for social change in online environments. 相似文献

Two experiments were conducted that examined the motivational and informational perspectives concerning learning advantages from self-controlled practice. Three groups were tasked with learning a novel skill; self-controlled (SC), yoked traditional (YT), and yoked with error estimation required during the acquisition phase (YE). Results from the delayed learning measures showed the YE group performed better than the SC and YT groups, for Expt. 1. A similar pattern emerged for Expt. 2, albeit, this was not significant. While there were no motivation differences across the groups in either experiment, a strong correlation in Expt. 2 was shown between error estimation capabilities, which were best for the YE group, and learning. These combined results suggest that informational processes contribute more to the self-controlled feedback learning advantage, relative to motivational contributions. 相似文献

Aim: This paper seeks to understand whether Maltese school counsellors are equipped to deal with dyslexic clients, considers whether specific strategies need to be used, and what positive effects, if any, counselling has on these clients. Previous studies: A literature review on self-concept and techniques on how to improve the self-concept of children with Learning Disabilities (LD)/Specific Learning Difficulties (SpLD) will place the current study in context. Method: Questionnaires (available from the authors on request) were distributed to all school counsellors on the island and analysed using content analysis. Findings: Findings from respondents indicate a need for more training, evidence-based knowledge of specific techniques when dealing effectively and successfully with dyslexic clients, specific specialised training to understand dyslexic clients and that counselling has a positive effect on dyslexic clients. 相似文献

In contrast to the motive literature, motivational intensity theory predicts that the implicit achievement motive (nAch) should only exert an indirect impact on effort by limiting the impact of task difficulty. To contrast these two views, sixty-eight participants with a low or high nAch performed an easy or difficult arithmetic task. Effort was assessed using cardiac pre-ejection period (PEP). Supporting motivational intensity theory’s view, PEP response was low in both easy-task conditions but stronger in the high-nAch group than in the low-nAch group in the difficult task. These findings suggest that nAch exerts an indirect effect on effort investment by setting the maximally justified effort instead of directly determining the amount of effort that is invested to satisfy the motive. 相似文献

Developmental stuttering is a frequent neurodevelopmental disorder with a complex neurobiological basis. Robust neural markers of stuttering include imbalanced activity of speech and motor related brain regions, and their impaired structural connectivity. The dynamic interaction of cortical regions is regulated by the cortico-basal ganglia-thalamo-cortical system with the supplementary motor area constituting a crucial cortical site. The SMA integrates information from different neural circuits, and manages information about motor programs such as self-initiated movements, motor sequences, and motor learning. Abnormal functioning of SMA is increasingly reported in stuttering, and has been recently indicated as an additional “neural marker” of DS: anatomical and functional data have documented abnormal structure and activity of the SMA, especially in motor and speech networks. Its connectivity is often impaired, especially when considering networks of the left hemisphere. Compatibly, recent data suggest that, in DS, SMA is part of a poorly synchronized neural network, thus resulting in a likely substrate for the appearance of DS symptoms. However, as evident when considering neural models of stuttering, the role of SMA has not been fully clarified. Herein, the available evidence is reviewed, which highlights the role of the SMA in DS as a neural “hub”, receiving and conveying altered information, thus “gating” the release of correct or abnormal motor plans. 相似文献

This contribution is a commentary to a special issue titled “Example-based learning: New theoretical perspectives and advances to a contemporary instructional approach” published in Applied Cognitive Psychology (2020). In the commentary, the presented research is discussed with respect to three extensions compared with previous research, namely, theoretical frameworks, learning scenarios and domains. It concludes with some suggestions for methodological advancements. 相似文献
