自恋人格调节信任博弈的结果评价

自恋人格个体表现出亲社会行为的减少和对他人的反馈敏感。信任是人类社会互动行为的基础,自恋人格特质可能影响他们的信任决策。为了探究自恋水平如何影响信任博弈中结果评价的大脑活动,本研究采用事件相关电位技术记录了38名被试完成单次信任博弈时的脑电波。行为结果发现相对高自恋者的信任选择率显著低于相对低自恋者的信任选择率。脑电结果表明,相对高自恋者信任损失反馈减互惠获利反馈所得的FRN差异波(d FRN)显著地大于相对低自恋者,并且相对高自恋者结果评价诱发的P300波幅显著地大于相对低自恋者。本研究提供了自恋人格个体信任博弈中结果评价的初步神经电生理学证据。     

Facilitating supervisees’ developing competence through supervisory conversation

Research on assessing supervisees’ professional development (PD) has been primarily focused on formal end-point, summative evaluations. Little attention has been given to the role that routine supervisory conversations play in formative PD evaluations. This study takes a situated/dialogical approach to explore how PD evaluations are locally proposed, recognized, transacted, and conversationally accomplished in the conversations of actual supervision practice. Informed by ethnomethodology, we discursively analyzed episodes of supervisory sessions selected by supervisory dyads, which they regarded as significant to the supervisee’s PD. We describe and exemplify five conversational Practices by which supervisory dyads brought about shared evaluations vis-à-vis the supervisee’s PD, through supervisory conversations.     

Beliefs as signals: A new function for belief

Beliefs serve at least two broad functions. First, they help us navigate the world. Second, they serve as signals to manipulate others. Philosophers and psychologists have focused on the first function while largely overlooking the second. This article advances a conception of signals and makes a prima facie case for a social signaling function for at least some beliefs. Truth and rational support are often irrelevant to the signaling function. If some beliefs evolved for a signaling function, then we should expect various biases that aid in the manipulation of others.     

Benefits from retrieval practice are greater for students with lower working memory capacity

We examined the effects of retrieval practice for students who varied in working memory capacity as a function of the lag between study of material and its initial test, whether or not feedback was given after the test, and the retention interval of the final test. We sought to determine whether a blend of these conditions exists that maximises benefits from retrieval practice for lower and higher working memory capacity students. College students learned general knowledge facts and then restudied the facts or were tested on them (with or without feedback) at lags of 0–9 intervening items. Final cued recall performance was better for tested items than for restudied items after both 10 minutes and 2 days, particularly for longer study–test lags. Furthermore, on the 2-day delayed test the benefits from retrieval practice with feedback were significantly greater for students with lower working memory capacity than for students with higher working memory capacity (r?=??.42). Retrieval practice may be an especially effective learning strategy for lower ability students.     

社交网站中的自我表露对青少年孤独感的影响:一个有调节的中介模型

本研究采用社交网站中的自我表露量表、自尊量表、感知积极反馈量表和孤独感量表对武汉市八所普通中学1588名11~19岁的中学生进行调查,考察社交网站中的自我表露和孤独感的关系,以及感知积极反馈在二者关系间的中介作用和自尊对这一中介作用的调节。结果显示：（1）在控制了性别、年龄和社交网站使用时间后,社交网站中的自我表露显著负向预测青少年孤独感;（2）感知积极反馈在社交网站中的自我表露和孤独感之间起部分中介作用;（3）社交网站中的自我表露经由感知积极反馈影响孤独感的中介作用受到自尊的调节。具体而言,感知积极反馈的中介效应只出现在高自尊者中,在低自尊者中并不存在上述中介作用。     

Gender differences in reaction to psychological pressure: evidence from tennis players

Using data on about 35,000 professional tennis matches, we test whether men and women react differently to psychological pressure arising from the outcomes of sequential stages in a competition. We show that, with respect to men, women losing the first set are much more likely to play poorly the second set. This suggests that women are more discouraged when facing the pressure of falling behind and receiving negative feedback. The gender differential is stronger in high-stake matches. On the other hand, when players are tied in the third set we do not find any gender difference in players’ reactions suggesting that women are as able as men to handle pressure if they do not lag behind. These results are robust controlling for measures of abilities and fitness of players, such as players’ rankings, players’ ex-ante winning probability, players’ rest, monetary prizes, players’ and tournaments’ fixed effects.     

Perceived impact of online written feedback on students’ writing and learning: a reflection

In this reflective study, I perceive the impact of my own written feedback on students’ academic writing skills in particular and on learning in general. Anchored on Schon’s reflection-on-action (ROA) framework, my reflection arose from a content analysis of my written feedback on 80 student drafts and 44 feedback responses. I found that my written feedback is of two types: focus on form and focus on meaning. Coding the feedback led to an identification of six feedback functions: instructive/using imperatives (18.36%); suggestive (15.31%); asking questions/probing (23.98%); stating a personal opinion (6.12%); corrective (29.59%); and affirming/negating (6.63%). The categorisation of feedback according to these functions was influenced by Wolsey’s feedback functions (2008) which was adapted by Alvarez, Espasa and Guasch. Results revealed that I employ corrective feedback, probing questions and instructive feedback more frequently than suggestive feedback, personal statement or affirmation/negation. I also found that my feedback on form (59%) is higher than my feedback on meaning (41%). I explain the relationship of these findings by identifying some confounding factors that enabled me to interrogate my assumptions, along with a discussion of their implications.     

文章标记对阅读理解困难学生信息保持的促进研究

根据阅读理解困难学生不能合理分配注意资源的特点,设置了文章标记这一能引导注意分配的外在线索,并以高层次的主题信息回忆和低层次的从属信息回忆为指标,考察阅读理解正常与困难学生接受标记影响的不同特点。结果表明:(1)文章标记对于阅读理解正常和困难学生的主题信息的回忆均有显著的促进效果,而对于阅读理解困难者的促进作用更为明显。(2)文章标记只促进了阅读理解困难者的从属信息的回忆,对于阅读正常者来说,文章标记反而有损于对从属信息的回忆。     

Enhancing frequency recording by developmental disabilities treatment staff

We evaluated a staff training and management package for increasing accuracy of recording frequency of problem behavior in a residential care facility. A multiple baseline design across the first and second work shifts showed that 2 of 8 participants increased their accuracy following in-service training, and all 8 improved during a condition with supervisor presence and feedback. Improvements were maintained when feedback was removed and generalized to activity periods when neither supervisor presence nor feedback was provided. Other staff behavior was not adversely affected by the intervention package.     

Rats' performance on variable-interval schedules with a linear feedback loop between response rate and reinforcement rate

Three experiments investigated whether rats are sensitive to the molar properties of a variable-interval (VI) schedule with a positive relation between response rate and reinforcement rate (i.e., a VI+ schedule). In Experiment 1, rats responded faster on a variable ratio (VR) schedule than on a VI+ schedule with an equivalent feedback function. Reinforced interresponse times (IRTs) were shorter on the VR as compared to the VI+ schedule. In Experiments 2 and 3, there was no systematic difference in response rates maintained by a VI+ schedule and a VI schedule yoked in terms of reinforcement rate. This was found both when the yoking procedure was between-subject (Experiment 2) and within-subject (Experiment 3). Mean reinforced IRTs were similar on both the VI+ and yoked VI schedules, but these values were more variable on the VI+ schedule. These results provided no evidence that rats are sensitive to the feedback function relating response rate to reinforcement rate on a VI+ schedule.
