Physical self-similarity enhances the gaze-cueing effect

Important social information can be gathered from the direction of another person's gaze, such as their intentions and aspects of the environment that are relevant to those intentions. Previous work has examined the effect of gaze on attention through the gaze-cueing effect: an enhancement of performance in detecting targets that appear where another person is looking. The present study investigated whether the physical self-similarity of a face could increase its impact on attention. Self-similarity was manipulated by morphing participants' faces with those of strangers. The effect of gaze direction on target detection was strongest for faces morphed with the participant's face. The results support previous work suggesting that self-similar faces are processed differently from dissimilar faces. The data also demonstrate that a face's similarity to one's own face influences the degree to which that face guides our attention in the environment.     

眼睛注视的知觉及其线索效应

对眼睛注视知觉、眼睛注视线索效应及其影响因素等相关研究进行了总结和分析。结果发现:(1)婴儿从一出生就对眼睛注视线索表现出强烈的敏感性,眼睛注视知觉对语言和社会等能力的发展有很大影响;(2)颞上沟是加工眼睛注视线索的特异神经结构,它与实时监控情绪和情感的杏仁核存在神经联结,成为社会认知神经系统的重要组成部分;(3)对眼睛注视线索的早期加工显示出特异的脑电活动模式;(4)眼睛注视线索效应与外周线索的反射式效应相类似,但持续时间较长;(5)眼睛注视线索效应不仅受面部结构信息的影响,也受自上而下加工等高水平认知因素的调节,并显示出明显的个体差异。对眼睛注视线索效应的进一步研究应涉及人格判断、喜好评价和心理理论等高级社会认知活动。     

连续和同时线索化条件下的返回抑制容量

利用线索-靶子模式进行了返回抑制容量的两个实验。实验一对外周数个位置连续线索化,实验二对外周数个位置同时线索化。结果表明：(1)在连续线索化条件下,当线索化位置是相邻时,返回抑制容量可以达到4个,当线索化位置是间隔时,返回抑制容量只有1个。(2)在同时线索化条件下．当线索化位置是相邻时,返回抑制容量可以达到3个,当线索化位置是间隔时．返回抑制容量只有1个。结果支持认为存在着两种不同的返回抑制的观点,即一种是弥散性的,其容量较大;另一种是集中性的,其容量只有一个。     

重复线索化和靶子注意定向对返回抑制的影响

在返回抑制范式下 ,利用线索—靶子模式进行了两个实验 ,以大学生为被试 ,以重复线索化次数来操纵线索化阶段的注意 ,以靶子的注意定向来操纵靶子加工阶段的注意 ,探讨注意对返回抑制的影响。实验一采用连续线索化方式 ,发现当靶子为自主性注意定向时 ,线索化次数对返回抑制有显著影响 ,线索化 3次时返回抑制值大于线索化 1次和 2次 ;当靶子为反射性注意定向时 ,线索化次数对返回抑制无影响。实验二采用交叉线索化方式 ,发现线索化次数对返回抑制的影响正好与实验一相反。两个实验一致表明 ,无论是线索化阶段的注意 ,还是靶子加工阶段的注意 ,均对返回抑制有显著影响 ;并且 ,在对返回抑制的影响上 ,二者存在显著交互作用。从而支持注意影响返回抑制的观点。该结果对返回抑制的机制研究有一定意义。     

The effect of spatial organization of targets and distractors on the capacity to selectively memorize objects in visual short-term memory

We conducted a series of experiments to explore how the spatial configuration of objects influences the selection and the processing of these objects in a visual short-term memory task. We designed a new experiment in which participants had to memorize 4 targets presented among 4 distractors. Targets were cued during the presentation of distractor objects. Their locations varied according to 4 spatial configurations. From the first to the last configuration, the distance between targets’ locations was progressively increased. The results revealed a high capacity to select and memorize targets embedded among distractors even when targets were extremely distant from each other. This capacity is discussed in relation to the unitary conception of attention, models of split attention, and the competitive interaction model. Finally, we propose that the spatial dispersion of objects has different effects on attentional allocation and processing stages. Thus, when targets are extremely distant from each other, attentional allocation becomes more difficult while processing becomes easier. This finding implicates that these 2 aspects of attention need to be more clearly distinguished in future research.     

邻近效应对多媒体学习中图文整合的影响:线索的作用

在多媒体学习中图文排列的邻近或远离会影响学习的效果。本研究操纵了多媒体呈现的图文排列位置,采用颜色作为线索引导注意,探讨了线索有无和图片-文字的空间位置对多媒体学习图文整合的影响。结果发现:图文邻近呈现时的保持测验和迁移测验成绩好于图文远离呈现,图文邻近呈现时学习者对关键兴趣区的进出次数更多,体现出以文字为导向的阅读模式。线索并没有单独影响学习成绩和注意分配;但结合图文位置后,发现有线索时图文邻近学习材料的注视次数、进出关键兴趣区的次数显著多于图文远离。研究认为:图文的邻近效应不仅提高学习者对知识的识记和理解,同时也影响了学习者的注意分配过程,图文邻近呈现有助于图片和文本信息的注意联结和知识整合;线索能使邻近效应得到凸显,更好地促进图文信息的注视加工,但没有改进学习的效果。     

基于双眼视差探讨深度知觉信息对背景线索效应的影响

背景线索效应是由重复场景导致搜索效率提高的现象。以往研究发现三维场景下能获得背景线索效应,但对三维场景下深度知觉线索信息如何影响空间场景提供有效线索引导注意仍缺乏实证研究。本研究以矩阵刺激为材料,通过设置不同的刺激项目水平数探讨深度知觉线索对背景线索效应的影响模式。结果发现:(1)在场景布局由较少项目构成时,深度知觉线索提供目标与刺激项目的有效联结,获得背景线索效应;(2)当刺激项目水平达到一定程度时,深度知觉线索增加了背景线索任务的搜索难度,干扰了重复场景中的背景信息对注意的指导性加工,背景线索效应消失。研究结果为三维场景下深度信息对空间场景中注意引导加工的影响提供了证据。     

Social attention across borders: A cross-cultural investigation of gaze cueing elicited by same- and other-ethnicity faces

The gaze-cueing effect is a robust phenomenon which illustrates how attention can be shaped by social factors. In four experiments, the present study explored the interaction between the ethnic membership of the participant and that of the face providing the gaze cue. Firstly, we aimed to further investigate the differential impact of White, Black, and Asian faces on the gaze-cueing effect in White individuals. Secondly, we aimed to explore, for the first time, the impact of faces belonging to different ethnicities on gaze cueing in Chinese participants. The results allowed to rule out alternative accounts and showed that White participants exhibit a gaze-cueing effect for White and Asian faces, but not for Black faces, consistent with previous studies. As regards Chinese participants, the overall findings suggested a stronger gaze-cueing effect for White faces than for Asian faces. The results are discussed with reference to differences in the perceived social status of the various groups, pointing to the need of taking into account different cultural contexts.     

Part-set cueing impairment & facilitation in semantic memory

The present study explored the influence of part-set cues in semantic memory using tests of “free” recall, reconstruction of order, and serial recall. Nine distinct categories of information were used (e.g., Zodiac signs, Harry Potter books, Star Wars films, planets). The results showed part-set cueing impairment for all three “free” recall sets, whereas part-set cueing facilitation was evident for five of the six ordered sets. Generally, the present results parallel those often observed across episodic tasks, which could indicate that similar mechanisms contribute to part-set cueing effects in both episodic and semantic memory. A novel anchoring explanation of part-set cueing facilitation in order and spatial tasks is provided.     

积极情绪提高背景线索学习的适应性

背景线索的学习缺乏适应性, 这种缺乏表现在两个方面：其一是难以在已习得的场景表征上捆绑一个新目标位置(Re-learning), 也就是场景表征的更新受阻; 其二是在习得一组场景表征后, 难以学习另一组全新场景(New-learning)。研究表明, 在旧场景表征上捆绑一个新目标位置的能力可能与注意范围大小有关, 而学习全新场景则需要重置学习功能。积极情绪可以有效扩大注意范围, 并改善对旧有认知模式的固着, 因此积极情绪启动将有可能提升背景线索学习的适应性。本研究采用效价为中性和积极的情绪性图片来启动对应的情绪, 探索旧场景捆绑新目标位置时和学习全新场景时, 背景线索的学习情况, 验证积极情绪是否可以提高背景线索学习中的适应性。实验发现, 积极情绪无法促进旧场景上捆绑新目标位置的背景线索学习(Re-learning), 但是可以促进全新场景的学习(New-learning)。该结果说明, 积极情绪可以提高被试的场景学习能力进而促进对全新场景的学习, 却无法减少由表征相似性引起的旧表征的自动检索, 进而无法改善旧表征的更新过程。
