亲社会视频游戏中的合作对博弈决策中合作行为的影响

以38名大学生和研究生为被试,采用Chicken Game实验范式测量合作行为,考察了单人和双人合作模式游戏后,性别和游戏习惯对玩家在博弈决策中合作行为的影响。结果表明：（1）双人合作模式游戏可以促进玩家在博弈决策中的合作行为;（2）双人合作模式游戏后,男玩家（相比女玩家）在博弈决策中的合作行为更多;（3）玩游戏的习惯影响博弈决策中的合作行为,相比于经常习惯与现实朋友玩游戏和独自玩游戏的玩家,经常习惯与网友玩游戏的玩家在双人合作模式游戏后的合作行为更多。本研究不仅证实了一般学习模型,也证实了亲社会合作类视频游戏可以有效促进博弈决策中的合作行为。     

事件持续时间对情景模型更新的影响

采用移动窗口技术,探讨文本阅读中事件持续时间对情景模型更新的影响。实验1探讨不同的事件持续时间对情景模型更新进程的影响。结果发现,情景模型的更新受到事件持续时间的影响;实验2探讨在不同的事件持续时间条件下,情景模型的更新符合动态观还是静态观,结果支持了情景模型更新的动态观。该研究表明,事件持续时间与时间转换大小之间的关系对情景模型的更新起着重要的作用。同时,情景模型的更新符合动态观。     

话题结构对语篇情绪更新的影响

读者在阅读理解的过程中, 能够推断出故事主角的情绪状态, 并能随着语篇中的情绪变化做出情绪更新。在加工情绪信息的同时, 读者也加工语篇结构方面的信息, 二者皆有可能随着语篇的展开而发生变化。本研究采用自定步速阅读的方法, 分别在外显和内隐两种情绪加工任务下, 考察话题结构对语篇情绪更新的影响。结果发现, 在实验1的外显情绪判断任务下, 话题结构未显示出对语篇情绪更新的作用; 在实验2和实验3的内隐情绪理解任务下, 话题延续时, 情绪转换句的阅读时间长于情绪延续句, 此时情绪更新需要额外的加工时间; 而话题转换时, 二者没有显著差异, 说明此时读者在新结构下建立当前句的情绪表征, 并不受到先前情绪的影响。     

记叙文阅读中主人公转换对情境模型更新的影响

应用探测任务范式和事件分割范式,以反应时、正确率、均字阅读时间等为指标,探讨主人公转换在记叙文情境模型更新中的作用。结果显示：（1）在主人公转换与事件转换一致时,主人公转换条件下的认知加工更加困难,表现为较长的反应时和均字阅读时间,以及较低的正确率和较高的分割概率。（2）在主人公转换与事件转换不一致条件下,主人公转换对反应时和均字阅读时间的影响显著降低,而分割概率与无转换条件无差异。这表明,事件是记叙文情境模型的核心;主人公维度仅在代表事件转换的条件下,才能引起情境模型的更新。     

公正世界信念对记忆偏差的影响

公正世界信念指人们需要相信他们所处的世界是一个公正有序的世界。本研究考察的是公正世界信念是否影响人们的记忆,让人产生记忆偏差。实验一中,被试首先阅读一则彩票中奖的新闻,然后阅读关于中奖者人品的描述,最后被试需要回忆中奖金额。结果发现,中奖者的个性品质影响对奖金数额的记忆。实验二中,两组被试分别阅读一则维护公正世界信念或威胁公正世界信念的无关故事,接下来程序与实验一相同。结果发现,预先激活的公正世界信念状态与中奖者个性品质在记忆结果上存在显著的交互效应。结果表明,公正世界信念能够导致记忆偏差。     

Effects of the Good Behavior Game on student and teacher behavior in an alternative school

The Good Behavior Game (GBG) is a classroom behavior management procedure that has been shown to be effective in reducing disruptive behavior across many settings and populations (Flower, McKenna, Bunuan, Muething, & Vega, 2014). We investigated the effects of the GBG on student and teacher behavior in two classrooms containing fourth‐ to eighth‐grade students in an alternative school for students with emotional and behavioral disorders. Results indicated the GBG reduced disruption and increased the teacher's use of praise relative to reprimands. Social validity measures, collected from both teachers and students, indicated strong approval of the GBG.     

情境模型中时间和空间维度更新的相互影响

运用移动窗口技术考察情境模型中时间和空间维度同时或序列转变时二者间的相互关系。结果发现：(1)时间和空间同时转变时, 二者存在易化关系, 但时间对空间的易化作用更大; (2)当二者序列转变时, 以中文为材料的结果只发现时间对空间的易化关系, 而以英语为材料的结果则发现存在双向易化关系, 但时间对空间的易化作用更大。据此, 情境模型中的时间和空间维度更新的捆绑－预期假设得到证明。     

The roles of planning,learning, and mental models in repeated dynamic decision making

Repeated search and decision making is a common consumer activity that should benefit from advanced planning. In three simulated shopping experiments, we find that people often fail to plan spontaneously or, when they do plan, do not use an appropriate mental model of the search problem. We also manipulate the mental models used by subjects and find that while our manipulation successfully encourages the development of appropriate mental models and improves performance when search costs are low, it does not result in the type of sophisticated mental model required to change strategies based on increased search costs. Finally, we show that the benefits of planning generalize to real world shopping behavior in a field experiment.     

Between a Rock and a Hard Place: The Deficit Model,the Diffusion Model and Publics in STS

The start of the twenty-first century witnessed the flourishing of both the biosciences (particularly genomics) and initiatives around public engagement in science, particularly in the UK and USA. STS researchers have both followed and fuelled this latter trend. Hence, it may be helpful to review the genealogy of these recent developments and of STS concern for the publics of science. This provides a way of assessing whether STS activities have been contributing to making the sciences more open and accountable to their publics. One trail returns to the institutionalisation of Public Understanding of Science (PUS) in the mid-1980s. The critique of this movement by STS scholars through reference to the deficit model (of public understanding of science) also figures here. However, less attention has been given to other modes of conceptualising science and publics, including what Cooter and Pumfrey label as the ‘diffusionist’ or ‘diffusion’ model (of scientific knowledge), which they contend entrenched traditional views of scientific knowledge and of publics as receivers of such knowledge. More recently, investigations of the making of science in diverse locations, attention to multiplicity and co-production have taken STS in new directions. Nevertheless, the legacies of both the deficit and diffusion models of science and publics continue to influence STS and its ‘regimes of truth’. Questions remain around STS researchers' persistent failure to acknowledge the diffusion model, in particular, and the consequent retrenchment of traditional views of how science works, limiting prospects for substantial public engagement and more open, democratic modes of science.     

最后通牒游戏中接收者拒绝行为的情绪义务模型

公平偏好使人们在面对不公平的分配时通常会有所表示,在最后通牒游戏中具体表现为对不公平报价的拒绝,有很多研究把拒绝的原因归结为不公平厌恶和互惠主义等社会偏好,但这并不能解释一些最后通牒变体游戏中的拒绝行为。但这恰恰支持了情绪义务模型。     

The representation of multiplication facts: developmental changes in the problem size, five, and tie effects

In this study, we investigated the development of basic effects that have been found in single-digit multiplication arithmetic: the problem size, five, and tie effects. Participants (9-, 10-, and 11-year-olds and adults) performed a production task on simple multiplication. The procedure replicated study [Canadian Journal of Psychology, Vol. 39, pp. 338-366], but the results show that the gradual decrease of the problem size effect ends in sixth grade. We report analyses on raw latencies and state trace analyses that take into account reaction time scaling as a function of age. The results show that 11-year-olds do not differ significantly from adults on any of the three effects. Before 11 years of age, interesting developmental changes occur.

The Effects of Sentence‐Level Context,Prior Word Knowledge,and Need for Cognition on Information Processing of Technical Language in Print Ads

An experiment was conducted to examine the effects of sentence‐level context, prior word knowledge, and need for cognition on responses to print ads for technical products. Words and phrases that help readers understand technical language in context increased the supportive arguments generated in response to ads, whereas prior word knowledge and need for cognition primarily influenced neutral thoughts. Only explanatory language facilitated the comprehension of product information. Explanatory language led to an increase in attitudes and purchase intent. Need for cognition had a positive influence on attitude formation when the context language was ambiguous, but decreased attitude formation when the context language was explanatory. Results are consistent with predictions guided by a comprehension elaboration model of persuasion.     

Oculomotor behavior and the level of repetition in motor practice: Effects on pupil dilation,eyeblinks and visual scanning

The benefits of less repetitive practice in motor learning have been explained by the increased demand for memory processes during the execution of motor skills. Recently, a new perspective associating increased demand for perception with less repetitive practice has also been proposed. Augmented information gathering and visual scanning characterize this higher perceptual demand. To extend our knowledge about mental effort and perceptual differences in practice organization, the association between oculomotor behavior and type of practice was investigated. We required participants to press four keys with different absolute and relative timing goals during the acquisition phase. An eye-tracker captured visual scanning of the skill’s absolute and relative information displayed on the screen. Participants were tested 24 h after acquisition by a retention and transfer test. A higher level of both pupil dilation and amount of eyeblinks indicated an increased mental effort in less repetitive practice compared to more repetitive practice. Visual scanning of the skill’s relative and absolute information was specific to the type of practice. The findings indicate many differences in oculomotor behavior associated with the practice schedule.     

The impact of verbal and physical abuse on distress,mental health,and intentions to quit in sports officials

Sports officials (e.g., referees, umpires, judges) can experience distress from a multitude of sources, including episodes of verbal and physical abuse from spectators, coaches, and athletes. Little is known about the impact of this abuse on mental health (MH) outcomes and intentions to quit, however. As such, the primary aims of this study were to survey the prevalence and frequency of abuse in sports officials and to examine relationships between abuse, distress, and subsequent MH and intentions to quit outcomes. Survey data were collected from 438 Gaelic Games match officials. Of these, 94.29% and 23.06% had experienced verbal and physical abuse respectively during their career. Verbal abuse was mostly experienced a couple of times a season (reported by 43.83% of officials) or every couple of games (31.48%), whereas physical abuse was predominantly experienced once or twice in a career (85.15%). Structural equation modelling was used to assess three alternative models that proposed the relationship between experiences of abuse, and MH and intentions to quit outcomes to be either 1) direct, 2) indirect, fully mediated by distress, or 3) both direct and indirect, partially mediated by distress. For verbal abuse, only the direct and indirect effects model achieved acceptable fit and significantly explained variance in mental wellbeing (9.4%), anxiety (15.2%), depression (15.6%), and intentions to quit (19.1%). For physical abuse, though higher distress was associated with poorer MH and greater intentions to quit, none of the models fully explained the relationships between all variables. These findings demonstrate, for the first time, relationships between abuse, subsequent distress, and MH outcomes. We highlight the urgent need to develop evidence-based psychological interventions to tackle abuse, manage conflict, and support the MH needs of sports officials.     

Structural validity of the Mental Health Continuum-Short Form: The bifactor model of emotional,social and psychological well-being

The Mental Health Continuum-Short Form (MHC-SF) is a growingly popular questionnaire designed to assess three components of well-being: emotional, social, and psychological. The main goal of the present study was to evaluate the structural validity of the MHC-SF and test the bifactor model of the MHC-SF, which includes one general factor and three specific factors of well-being. Sample 1 consisted of 1095 Serbian students (aged 18–26 years), while Sample 2 included 325 Serbian adults (aged 27–63 years). The bifactor model of the MHC-SF yielded the best fit to the data across the two samples. The results showed that the general factor of well-being accounted for substantially greater amount of variance of the MHC-SF than three specific factors of well-being. After controlling for the general factor, three specific factors explained a small portion of variance in well-being. In addition, the three subscales of the MHC-SF showed low reliability as estimated by omega-subscale coefficients, indicating that these subscales comprise too small amount of reliable variance to interpret. The present findings suggest that researchers should not calculate separate scores for three types of well-being when using the MHC-SF and that alternative measures of specific components of well-being should be considered.     

The Effects of Age,Sex and Alzheimer's Disease on Strategy Use During Verbal Fluency Tasks

ABSTRACT

Clustering and switching strategies during phonemic and semantic verbal fluency tasks were investigated in healthy adults (n = 193, 86 males, 20–90 years) in young, middle-aged, young–old, and old–old age groups (Study 1). Older groups produced fewer total words and lower switching scores; males relied more on clustering and females on switching to produce equivalent output. In Study 2, early Alzheimer's disease participants, compared to healthy older adults, (n = 26 per group) produced fewer total words and smaller average clusters. Sex, age, and clinical differences on switching and clustering strategies support a dual processing model of verbal fluency.     

The effects of feedback on the gender differences in the performance in a chronometric mental-rotation test

ABSTRACT

Gender differences favouring males are often found in mental-rotation tests and are usually smaller in chronometric than in psychometric test. The individual feedback in the chronometric test could be an explanation for the comparable performance of males and females. To test this hypothesis, 102 undergraduate students (60 females, 42 males) participated in a chronometric mental-rotation study with or without feedback. A subsample of 41 participants was asked to report their confidence about their performance in the test. In reaction time, males outperformed females and participants in the feedback condition reacted faster than participants without feedback. A significant interaction of gender and condition was found. Only females had an advantage in the feedback condition in reaction time while there was no difference for males. Males reported higher scores of confidence. Feedback seemed to help females especially to react faster. Confidence levels are discussed as reasons for differences between conditions and genders.     

Effects of an Auditory Model on the Learning of Relative and Absolute Timing

The effects of an auditory model on the learning of relative and absolute timing were examined. In 2 experiments, participants attempted to learn to produce a 1,000- or 1,600-ms sequence of 5 key presses with a specific relative-timing pattern. In each experiment, participants were, or were not, provided an auditory model that consisted of a series of tones that were temporally spaced according to the criterion relative-timing pattern. In Experiment 1, participants (n = 14) given the auditory template exhibited better relative- and absolute-timing performance than participants (n = 14) not given the auditory template. In Experiment 2, auditory and no-auditory template groups again were tested, but in that experiment each physical practice participant (n = 16) was paired during acquisition with an observer (n = 16). The observer was privy to all instructions as well as auditory and visual information that was provided the physical practice participant. The results replicated the results of Experiment 1: Relative-timing information was enhanced by the auditory template for both the physical and observation practice participants. Absolute timing was improved only when the auditory model was coupled with physical practice. Consistent with the proposal of D. M. Scully and K. M. Newell (1985), modeled timing information in physical and observational practice benefited the learning of the relative-timing features of the task, but physical practice was required to enhance absolute timing.
