Signalling signalhood and the emergence of communication

A unique hallmark of human language is that it uses signals that are both learnt and symbolic. The emergence of such signals was therefore a defining event in human cognitive evolution, yet very little is known about how such a process occurs. Previous work provides some insights on how meaning can become attached to form, but a more foundational issue is presently unaddressed. How does a signal signal its own signalhood? That is, how do humans even know that communicative behaviour is indeed communicative in nature? We introduce an experimental game that has been designed to tackle this problem. We find that it is commonly resolved with a bootstrapping process, and that this process influences the final form of the communication system. Furthermore, sufficient common ground is observed to be integral to the recognition of signalhood, and the emergence of dialogue is observed to be the key step in the development of a system that can be employed to achieve shared goals.     

AN EVALUATION OF RESURGENCE DURING TREATMENT WITH FUNCTIONAL COMMUNICATION TRAINING

Extinction‐induced resurgence is the recurrence of previously reinforced behavior when another behavior is placed on extinction (Lieving, Hagopian, Long, & O'Connor, 2004). This phenomenon may account for some instances of treatment relapse when problem behavior recovers during extinction‐based treatments. The current study sought to determine whether resurgence of problem behavior would reliably occur with 5 participants who received treatment with FCT. Results showed that problem behavior reemerged for all but 1 participant when the communicative response was exposed to extinction or thin schedules of reinforcement. These findings suggest that resurgence may account for some instances of response recovery during treatment, and that the described procedure may be useful for the further study of resurgence and eventual prevention of this phenomenon.     

THE INFLUENCE OF MATCHING AND MOTOR‐IMITATION ABILITIES ON RAPID ACQUISITION OF MANUAL SIGNS AND EXCHANGE‐BASED COMMUNICATIVE RESPONSES

Establishing a relation between existing skills and acquisition of communicative responses may be useful in guiding selection of alternative communication systems. Matching and motor‐imitation skills were assessed for 6 children with developmental disabilities, followed by training to request the same set of preferred items using exchange‐based communication and manual signs. Three participants displayed both skills and rapidly acquired both communicative response forms. Three others displayed neither skill; 1 mastered exchange‐based responses but not manual signs, and neither of the other 2 easily acquired either response form.     

Prairie dog alarm calls encode labels about predator colors

Some animals have the cognitive capacity to differentiate between different species of predators and generate different alarm calls in response. However, the presence of any addition information that might be encoded into alarm calls has been largely unexplored. In the present study, three similar-sized human females walked through a Gunnison’s prairie dog (Cynomys gunnisoni) colony wearing each of three different-colored shirts: blue, green, and yellow. We recorded the alarm calls and used discriminant function analysis to assess whether the calls for the different-colored shirts were significantly different. The results showed that the alarm calls for the blue and the yellow shirts were significantly different, but the green shirt calls were not significantly different from the calls for the yellow shirt. The colors that were detected, with corresponding encoding into alarm calls, reflect the visual perceptual abilities of the prairie dogs. This study suggests that prairie dogs are able to incorporate labels about the individual characteristics of predators into their alarm calls, and that the complexity of information contained in animal alarm calls may be greater than has been previously believed.     

虚拟社会关系的心理学研究及展望

随着计算机及网络的普及,一种新型的、不同于传统“面对面（facetoface）”交往的社会关系——虚拟社会关系（virtualsocialrelationship）——已逐渐形成。该文从心理学角度对虚拟交往的动机、影响虚拟关系发展的因素及“虚拟”与“现实”的关系等进行了阐述,并在此基础上对未来虚拟社会关系的研究取向进行了展望,认为虚拟社会关系形成的心理基础、心理机制等将成为今后的研究热点     

性别同一性的形成及研究角度发展

性别的同一性是自我同一性的一部分,是人格和社会化发展的重要内容。性别的同一性概念已经从性同一性转移到性别同一性。对性别同一性的研究角度经过了概念认知、图式认知和社会认知的探索,目前开始进入人际关系角度的研究。最后,提出了对性别同一性未来的研究展望。     

Social Influence on Political Judgments: The Case of Presidential Debates

Four experiments investigated the extent to which judgments of candidate performance in presidential debates could be influenced by the mere knowledge of others' reactions. In Experiments 1 and 2 participants watched an intact version of a debate or an edited version in which either "soundbite" one-liners or the audience reaction to those soundbites were removed. In Experiment 3 participants saw what was supposedly the reaction of their fellow participants on screen during the debate. Participants in Experiment 4 were exposed to the reactions of live confederates as they watched the last debate of an active presidential campaign. In all studies, audience reactions produced large shifts in participants' judgments of performance. The results illustrate the power of social context to strongly influence individuals' judgments of even large amounts of relevant, important information, and they support the categorization of presidential debates as ambiguous stimuli, fertile ground for informational social influence.     

人际信任研究及其在组织管理中的应用

组织中的人际信任,可以促进组织成员之间的沟通,增强组织凝聚力,提高工作效率,从而降低组织运行和管理成本。因此,心理学、社会学和管理学等从各自的角度对组织中信任问题进行了大量研究。该文综述了国内、外对组织人际信任的研究。首先探讨了几种基本的信任定义;然后重点介绍了在组织中建立人际信任以及导致信任破坏的个人因素、人际互动因素以及组织环境、社会文化等宏观因素;最后从组织管理的角度展望了信任研究的未来方向。     

视觉观点采择中自我中心性偏差的抑制和归因之争

自我中心性偏差是社交失败的重要原因,但其产生机制还存在争议。以往研究存在抑制性选择模型与流利性错误归因两种理论观点:前者认为对自身观点的抑制失败会导致自我中心性偏差;后者则认为错误地选择自身更为流畅的信息会导致自我中心性偏差。为整合上述争论,提出抑制-归因协同作用模型,认为抑制和归因两种加工或可共同导致自我中心性偏差。未来研究应借助精巧的研究范式和特殊被试群体,进一步验证该模型。     

Intruders of differing reproductive status alter aggression differentially in early and late pregnant mice

Independent groups of early and late pregnant mice, housed individually, were observed with an intruder in their home cage. The intruders were either males, virgin, early, or late pregnant females. Male intruders were sniffed less, but more frequently and more severely attacked, than any type of female intruder, both by early and by late pregnant residents. While early pregnant females behaved similarly with the three types of female intruders, late pregnant animals treated them differently: they showed practically no aggression to late pregnant intruders, more to early pregnant ones and were most aggressive towards virgin female intruders. The possible relation of these findings to reproductive behaviour is discussed.
