Making Sense of the Hands and Mouth: The Role of “Secondary” Cues to Meaning in British Sign Language and English

Successful face-to-face communication involves multiple channels, notably hand gestures in addition to speech for spoken language, and mouth patterns in addition to manual signs for sign language. In four experiments, we assess the extent to which comprehenders of British Sign Language (BSL) and English rely, respectively, on cues from the hands and the mouth in accessing meaning. We created congruent and incongruent combinations of BSL manual signs and mouthings and English speech and gesture by video manipulation and asked participants to carry out a picture-matching task. When participants were instructed to pay attention only to the primary channel, incongruent “secondary” cues still affected performance, showing that these are reliably used for comprehension. When both cues were relevant, the languages diverged: Hand gestures continued to be used in English, but mouth movements did not in BSL. Moreover, non-fluent speakers and signers varied in the use of these cues: Gestures were found to be more important for non-native than native speakers; mouth movements were found to be less important for non-fluent signers. We discuss the results in terms of the information provided by different communicative channels, which combine to provide meaningful information.     

A model statement does not enhance the verifiability approach

The present experiment investigated to what extent providing participants with a model statement influences the ability of the verifiability approach to detect deception. Participants gave a true and false statement about a negative autobiographical event, with half of the participants receiving a detailed model statement just before giving their statement. We expected false statements to include more nonverifiable and less verifiable details than true statements and that providing a model statement would increase these differences. False statements indeed included more nonverifiable details than truthful statements but did not differ in the number of verifiable details. True statements included a higher ratio of verifiable details. The model statement encouraged participants to give a longer and more detailed statement. However, it prompted participants to increase the number of included verifiable—and not nonverifiable—details, regardless of veracity. Using a model statement did not influence the discriminability of the verifiability approach.     

注视线索对消费者的影响机制

心理学研究发现眼睛注视线索不仅能够引导社会性注意,还会影响个体对物品的感觉和知觉。注视线索对消费者的影响体现在认知和态度两方面：一方面,模特注视线索能够引导消费者注意,增强消费者对广告或产品的记忆;另一方面,模特注视线索会影响消费者对产品的喜欢程度和购买意愿,以及对服务人员的评价。未来可以从产品、消费者、消费情景及注视线索发起人等方面进一步探索注视线索对消费者心理和行为的影响。     

Invisible displacement understanding in domestic dogs (<Emphasis Type="Italic">Canis familiaris</Emphasis>): the role of visual cues in search behavior

Recently, (Collier-Baker E, Davis JM, Suddendorf T (2004) J Comp Psychol 118:421–433) suggested that domestic dogs do not understand invisible displacements. In the present study, we further investigated the hypothesis that the search behavior of domestic dogs in invisible displacements is guided by various visual cues inherent to the task rather than by mental representation of an object’s past trajectory. Specifically, we examined the role of the experimenter as a function of the final position of the displacement device in the search behavior of domestic dogs. Visible and invisible displacement problems were administered to dogs (N = 11) under two conditions. In the Visible-experimenter condition, the experimenter was visible whereas in the Concealed-experimenter condition, the experimenter was visibly occluded behind a large rigid barrier. Our data supported the conclusion that dogs do not understand invisible displacements but primarily search as a function of the final position of the displacement device and, to a lesser extent, the position of the experimenter.     

Interaction between locale and taxon strategies in human spatial learning

Three computer-based experiments which tested human participants in a non-immersive virtual watermaze task sought to determine factors which dictate whether the presence of a visual platform disrupts locale learning and taxon learning. In Experiment 1, the visible platform disrupted locale but not taxon learning based on viewpoint-independent and viewpoint-dependent information, respectively. In Experiment 2, taxon learning based on non-geometric cues providing viewpoint-dependent information was disrupted by the visible platform when the cues required relational information to disambiguate them from other cues. Experiment 3 placed participants in an isosceles triangular pool. The presence of the visible platform did not disrupt the encoding of relational information provided by shape of the pool. These results support the notion that geometric cues are encoded in a separate module which is impenetrable to non-geometric cues not creating the shape of the environment.     

情境线索对社会认知内容推断的影响

本研究考察了情境线索对社会目标不同内容维度之间的推断的影响。研究一发现,缺乏情境线索时,两个基本维度热情和能力之间呈一种正向推断。研究二发现,当情境线索明确指向高能力时,高热情描述会导致低能力推断,同时也引发了消极的行为倾向。研究三进一步考察了热情的两个子维度社交性和道德性之间的推断,结果发现描述社交性职业的社交性信息或者描述道德性职业的道德性信息时,对目标对象的整体评价和行为意愿都更为积极。本研究表明,情境的预期性线索为社会认知内容的推断提供了基本的认知框架,当信息呈现与情境预期相匹配时,更容易产生积极推断。     

Use it or lose it: purchase acceleration effects of time‐limited promotions

While researchers have examined the impact of retail promotions on purchase acceleration in the past, the distinction between time‐limited and time‐independent promotions has not been made in this context. In this paper, the authors report findings from two studies. In Study 1, it was found that promotions of short duration (time‐limited), such as store coupons, accelerate purchases, whereas promotions of longer duration (time‐independent), such as manufacturer's coupons, have no such impact. In Study 2, the impact of semantic cues was examined highlighting the time‐limited nature of promotions (such as ‘10 Hours Only Sale’), impact on purchase willingness, intent to search further for deals and attitudes towards the deal.

不同线索下 3～9岁儿童的情绪认知、助人意向和助人行为

本研究通过个别施测,考察了600名3～9岁儿童在不同线索下的情绪认知、助人意向和助人行为。结果表明,情绪认知成绩随年龄的增长而提高,对情境和表情线索一致任务的认知优于对矛盾线索的认知,情绪认知利用线索随年龄的增长统合型逐渐取代表情依存型和情境依存型而占优势;不同难度的线索任务制约了儿童的助人意向和助人行为,情绪认知对助人意向和助人行为有不同的作用模式。     

无意识目标追求的行为特征、机制及影响因素

无意识目标追求是指个体自动地追求由情境线索激活的目标, 而全然不知目标对自己行为的导向作用。无意识目标追求具有灵活性、抑制性和坚持性。无意识目标追求经由行动的无意识准备和目标价值的自动评估与努力过程实现。积极情绪、内隐态度和人际关系影响无意识目标追求。未来研究需要进一步探讨无意识目标追求的影响因素, 完善无意识目标追求的机制, 探究无意识目标追求结果对个体心理和行为的影响, 提高研究结果的生态效度, 拓展应用研究。     

社交线索对害羞者社交行为倾向的影响

以89名高害羞者和84名低害羞者为被试,以基于虚拟社交情境中的愤怒面孔线索、愉快面孔线索和中性面孔线索为刺激材料,采用线索暴露范式探讨了社交线索对害羞者社交行为倾向的影响。实验结果表明,相对于中性面孔线索,愤怒面孔线索对高害羞者的社交退缩行为倾向具有显著的诱发作用,而愉快面孔线索对其社交行为倾向具有促进作用。该研究为解释高害羞者社交障碍的特征提供了实验证据,并为如何减少高害羞者的退缩行为进而消除其社交障碍提供了一定的思路。
