说谎行为及其识别的心理学研究

国外关于说谎行为及其识别的心理学研究主要包括对说谎时行为表现的研究、对说谎识别准确率的研究及测谎技术的开发与应用。说谎是人类社会普遍存在的现象,但研究显示人们对说谎行为的识别准确率并不显著高于随机判断的概率。说谎者通常所表现出来的与说真话时不同的特点被称为“线索”,人们对说谎线索的看法与说谎者的实际行为表现并不一致。动机、互动特点、个体差异、沟通情境等因素对说谎和识别行为都会产生影响。网络沟通方式下的说谎行为呈现出一些新的特点     

基于线索的顿悟问题解决:图式和表征操作的影响

对小学、初中、高中学生共270名被试在不同线索条件下解决顿悟问题T puzzle的表现进行研究,结果表明:(1)由于图式运用水平的发展,知觉定势在单一线索下对高二被试的限制作用更为明显,导致小学五年级和初中二年级被试的问题解决时间短于高中二年级;(2)由于表征操作能力发展水平的限制,增大需操作表征数目的线索不利于五年级被试的问题解决;较高的表征操作能力发展水平使得高二被试在多重线索下有更好的解决成绩;(3)与图式相关的线索并不能有效提高儿童解决顿悟问题的效率。     

What constrains children's learning of novel shape terms?

In this study, 3-year-olds matched on vocabulary score were taught three new shape terms by one of three types of linguistic contrast: corrective, semantic, or referential. A 5-week training paradigm implemented four training sessions and four assessment sessions. Corrective contrast ("This is concave, it is not square," where square is the child's label for the target) produced more learning than did either semantic or referential contrast. In addition, regardless of group, more was learned about those targets that were classified more variably at pretest. Avoidance of lexical overlap (i.e., using more than one term for the same dimension) might make it more difficult for children to learn new dimensional adjectives, and a "shape bias" might make learning shape terms easier. However, children's expectations about the speaker's communicative intent interacted with the potential benefits of contrast in the semantic condition, and children in that group learned no more than did controls.     

The Interplay of Cross‐Situational Word Learning and Sentence‐Level Constraints

A variety of mechanisms contribute to word learning. Learners can track co‐occurring words and referents across situations in a bottom‐up manner (cross‐situational word learning, CSWL). Equally, they can exploit sentential contexts, relying on top–down information such as verb–argument relations and world knowledge, offering immediate constraints on meaning (word learning based on sentence‐level constraints, SLCL). When combined, CSWL and SLCL potentially modulate each other's influence, revealing how word learners deal with multiple mechanisms simultaneously: Do they use all mechanisms? Prefer one? Is their strategy context dependent? Three experiments conducted with adult learners reveal that learners prioritize SLCL over CSWL. CSWL is applied in addition to SLCL only if SLCL is not perfectly disambiguating, thereby complementing or competing with it. These studies demonstrate the importance of investigating word‐learning mechanisms simultaneously, revealing important characteristics of their interaction in more naturalistic learning environments.     

Coaching cues in amateur boxing: An analysis of ringside feedback provided between rounds of competition

Feedback is commonly employed to enhance motor learning and performance. While numerous studies have investigated the causal effects of feedback on motor learning, an analysis of real-time feedback provided during training and competitive sporting environments is lacking. Therefore, the feedback provided by 12 boxing coaches to athletes between rounds of the 2015 Australian Boxing Championships was recorded and transcribed. The feedback statements were then analyzed according to three feedback variables that have been shown to be critical for optimizing performance: Attentional focus (external, internal, neutral), autonomy support (autonomy-supportive, controlling, neutral), and feedback valence (positive, negative, neutral). Collectively, 445 feedback statements provided during 25 bouts, of which 14 were won and 11 were lost, were analyzed for each of the three categories. Coaches provided on average 8 feedback statements per round. Excluding neutral statements, coaches delivered more internal (15%) compared with external focus feedback (6%), more controlling (53%) compared with autonomy-supportive feedback (6%), and more positive (29%) relative to negative feedback (12%). Furthermore, during winning bouts coaches delivered less internal (12% vs. 19%), less controlling (48% vs. 58%), and more positive (36% vs. 18%) feedback, when compared with losing bouts. These results demonstrate for the first time the type and frequency of feedback delivered during amateur boxing bouts. While these findings may or may not reflect causal relationships, it is interesting that feedback that has been found to enhance motor performance was more often used during winning rather than losing bouts.     

从信任违背到信任修复:道德情绪的作用机制

早期学者已经从认知的角度分析信任违背的原因及修复方式。近年来,情绪对信任修复的影响引起了重点关注,但是情绪在其中的作用机制并未得到解答。当前的研究主要从情绪影响信任的线索依赖效应和离散情绪(内疚、羞愧、愤怒、悲伤等)对信任修复的影响这两个角度着手研究情绪对信任修复的影响。通过文献梳理发现内疚和共情两种道德情绪是影响信任修复最重要的情绪因素:内疚能够促进受信方做出补偿行为,共情能够促进信任方宽恕他人。基于此构建了道德情绪的信任修复模型,并考虑了目标线索和信任方的特质性宽恕的调节作用。同时建议未来的研究进一步探讨其他离散情绪尤其是道德情绪对信任修复的作用,并关注情境与情绪的交互作用。     

What did you say? Self‐regulatory depletion impairs interpretation of vocal cues

Evidence indicates that people are motivated to interpret environmental cues to belongingness, but doing so can be challenging. Prior evidence shows that the self's regulatory resources are consumed when interpreting complex facial displays; with this study, we examined how the depletion of such resources may impact the ability to interpret vocal tones. Results showed that depletion decreased accuracy in identifying complex (vs. simple) vocal cues, which extends prior work and offers a more comprehensive understanding of the relationship between self‐regulatory resources and the ability to effectively interpret one's social environment.     

Effect of external HMI for automated vehicles (AVs) on drivers’ ability to infer the AV motion intention: A field experiment

A field experiment was conducted aiming to shed light on how drivers negotiate an ambiguous traffic situation when encountering an autonomous vehicle (AV) in the presence of a yielding intention signal (AV with eHMI) or not (AV without eHMI). A traffic conflict scenario was created with two opposing vehicles instructed to perform a left turn at a four-way junction, at the same point in time. Forty participants were assigned to two groups encountering either an AV with eHMI or an AV without eHMI. To check for equivalence across the two groups, both groups also encountered a conventional vehicle (CV). Results showed that the two groups performed similarly during encounters with a CV. During encounters with AV, however, participants provided with the eHMI maintained higher speed before the AV and finished their maneuver quicker than when they were not provided with eHMI. Additionally participants provided with eHMI rated higher their ability to infer the AV intention before coming to a full-stop than those provided without eHMI. The above findings indicate that the presence of eHMI on AV can accelerate drivers’ inferences about yielding intention of an AV, and have the potential to optimize AV-driver interaction in ambiguous traffic situations.     

建议距离和线索丰富性对建议采纳的影响

基于社会判断理论,研究以80名大学生为被试,通过JAS范式考察了建议距离对建议采纳和自信心变化的影响以及线索丰富性在这一过程中的作用。结果发现随着建议距离的增加,建议权重仅在线索信息较丰富的情况下呈先增后减的倒U型趋势,而绝对观点转变和自信心变化均不受线索丰富性的影响,分别呈递增和递减趋势。即建议距离对不同建议采纳指标有不同影响,建议距离与建议权重之间存在倒U曲线关系且线索丰富性起到了调节作用。     

孤独症谱系障碍者基于运动线索的生命知觉

生命知觉是人们将客体自动加工为可以相互作用的生命体的认知过程。ASD者基于运动线索的生命知觉的研究方法包括追逐检测范式、运动特性参数化范式和因果知觉范例。其生命知觉的异常主要表现为运动信息整合能力不足、社会因果知觉缺陷以及对高复杂度运动的神经追踪较弱。相关理论假设从神经病理、认知加工及脑结构和功能障碍层面进行解释。未来应提升研究方法的生态效度,推进追踪与系统化研究,促进相关干预方案的开发。
