注视方向的知觉对注视追随行为的影响

他人的注视线索可诱导观察者将注意自动地转移到该线索所指示的方向上去(注视追随), 但仍不清楚注视方向的知觉在注视追随中起到何种作用。本研究结合注视适应和注视线索提示范式发现：知觉到的注视线索角度越大, 其线索提示效应越强; 知觉适应后被试判断注视方向的准确性下降, 注视线索引起的注意转移量显著减少。可见, 对注视方向的知觉能直接影响注视追随行为, 而注视方向抽取受到刺激显著性(注视角度)和知觉适应等因素的调节。这提示：在意识状态下, 注视知觉与注视追随存在直接联系, 即可能存在从注视知觉系统到注意转移系统的皮层加工通路; 注视追随并非纯粹的反射式加工, 它受自上而下知觉经验的调节。     

The processing of auditory and visual recognition of self-stimuli

This study examined self-recognition processing in both the auditory and visual modalities by determining how comparable hearing a recording of one’s own voice was to seeing photograph of one’s own face. We also investigated whether the simultaneous presentation of auditory and visual self-stimuli would either facilitate or inhibit self-identification. Ninety-one participants completed reaction-time tasks of self-recognition when presented with their own faces, own voices, and combinations of the two. Reaction time and errors made when responding with both the right and left hand were recorded to determine if there were lateralization effects on these tasks. Our findings showed that visual self-recognition for facial photographs appears to be superior to auditory self-recognition for voice recordings. Furthermore, a combined presentation of one’s own face and voice appeared to inhibit rather than facilitate self-recognition and there was a left-hand advantage for reaction time on the combined-presentation tasks.     

研究心理理论的新方法——失言识别任务

心理理论是对他人心理状态进行推论的能力。考察心理理论的经典范式是错误信念任务, 而青少年和成人在这种任务上可能出现天花板效应。为了测量青少年和成人的心理理论, Valerie E. Stone和她的合作者设计了失言识别任务。征求了Stone意见, 对失言识别任务的提出、构成、使用进行了介绍, 说明了该任务相对于经典范式的优势; 与此同时, 分析了失言识别任务范式存在的一些问题, 比如其效度指标问题, 与言语能力的分离问题, 失言识别任务与执行功能之间的分离等。未来研究可以尝试编制失言识别任务的本土化的量表, 并利用其探讨年长个体心理理论水平发展变化的规律。     

颜色知觉突显对预览效益的影响

本研究通过预览搜索范式考察靶子在颜色高突显情况下的预览效益,探讨其优先选择机制。结果发现在靶子颜色高突显的情况下,预览效益没有出现,说明预览效益的出现有其一定的条件和限制,并为基于刺激特征的抑制的解释提供了支持证据。本文还探讨了预览效益消退的可能原因。     

Race-specific perceptual discrimination improvement following short individuation training with faces

This study explores the effect of individuation training on the acquisition of race-specific expertise. First, we investigated whether practice individuating other-race faces yields improvement in perceptual discrimination for novel faces of that race. Second, we asked whether there was similar improvement for novel faces of a different race for which participants received equal practice, but in an orthogonal task that did not require individuation. Caucasian participants were trained to individuate faces of one race (African American or Hispanic) and to make difficult eye-luminance judgments on faces of the other race. By equating these tasks we are able to rule out raw experience, visual attention, or performance/success-induced positivity as the critical factors that produce race-specific improvements. These results indicate that individuation practice is one mechanism through which cognitive, perceptual, and/or social processes promote growth of the own-race face recognition advantage.     

Is the inversion effect in rhesus monkeys face-specific?

This study investigated the face inversion effect in rhesus monkeys (Macaca mulatta). Face stimuli consisted of ten black-and-white examples of unfamiliar rhesus monkey faces, brown capuchin faces, and human faces. Two non-face categories included ten examples of automobiles and abstract shapes. All stimuli were presented in a sequential matching-to-sample format using an automated joystick-testing paradigm. Subjects performed significantly better on upright than on inverted presentations of automobiles, rhesus monkey and capuchin faces, but not human faces or abstract shapes. These results are inconsistent with data from humans and chimpanzees that show the inversion effect only for categories of stimuli for which subjects have developed expertise. The inversion effect in rhesus monkeys does not appear to be face-specific, and should therefore not be used as a marker of specialized face processing in this species.

The Alienating Mirror: Toward a Hegelian Critique of Lacan on Ego-Formation

This article brings out certain philosophical difficulties in Lacan’s account of the mirror stage, the initial moment of the subject’s development. For Lacan, the “original organization of the forms of the ego” is “precipitated” in an infant’s self-recognition in a mirror image; this event is explicitly prior to any social interactions. A Hegelian objection to the Lacanian account argues that social interaction and recognition of others by infants are necessary prerequisites for infants’ capacity to recognize themselves in a mirror image. Thus mutual recognition with another, rather than self-recognition in a mirror, is what makes possible subsequent ego-formation and self-consciousness. This intersubjective critique suggests that many of the psychoanalytic consequences that Lacan derives from the mirror stage (e.g., alienation, narcissism, and aggressivity) may need to be rethought.

自闭症谱系障碍者面孔识别的神经机制

自闭症谱系障碍（ASD）是一种心理状况的谱系障碍,其症状是社交及沟通上的广泛性异常、异常局限性的兴趣和高度重复性的刻板行为。包括自闭症、亚斯伯格症候群和待分类的广泛性发展障碍3类。研究主要以事件相关电位和功能性磁共振成像两种技术为线索,通过深入分析ASD患者在面孔识别认知过程中脑的异常变化,探讨其面孔识别障碍的神经机制问题。研究表明,ASD患者面孔识别能力的损伤主要与N170、N300、P400和Nc等ERPs成份异常及梭状回面孔区和杏仁核的低激活有关。研究推论ASD患者面孔识别障碍是多个异常脑区联合作用的结果,且主要受异常脑区的数量和损伤程度的影响。     

“鸡尾酒会”环境中的知觉线索的去掩蔽作用

在有多人同时说话的嘈杂环境中,为什么具有正常听力的人能在一定的程度上听懂目标语句？研究这个著名的“鸡尾酒会”问题的一个新进展是将干扰言语的作用区分出了能量掩蔽和信息掩蔽两种成分。与发生在外周系统的能量掩蔽不同,信息掩蔽发生在心理层次并受到认知过程的调节。因此,主观空间分离、与目标语句节奏相关的视觉信号以及对目标语句某些特征的熟悉程度等知觉线索都具有去掩蔽作用。考察可减少信息掩蔽的知觉线索的交互作用及其高级认知调节是今后重要的研究内容
