情绪信息的多通道整合

自然环境中人类情绪信息的交流是依靠多个感觉通道实现的,多通道整合是情绪加工的基础。近年来的行为学、电生理学与神经成像的研究表明,情绪信息的加工具有跨通道自动整合的特点,它发生在认知加工的早期阶段,与颞上回、颞中回、海马旁回和丘脑等脑区密切相关。不同情绪的整合既有共同的神经基础,又有各自独特的加工区域。情绪信息的整合机制还可能与加工类型及注意资源有关。在未来研究中,实验的标准化、动态化、自然化有助于提高研究的准确性和研究间的可比性,而对特殊群体的研究,以及综合研究情绪加工与注意等其他认知过程则有助于我们进一步探索多通道整合的神经机制。     

The mechanism underlying inhibition of saccadic return

Human observers take longer to re-direct gaze to a previously fixated location. Although there has been some exploration of the characteristics of inhibition of saccadic return (ISR), the exact mechanisms by which ISR operates are currently unknown. In the framework of accumulation models of response times, in which evidence is integrated over time to a response threshold, ISR could reflect a reduction in the rate of accumulation for saccades to return locations or an increase in the effective criterion for response. In two experiments, participants generated sequences of three saccades, in response to a peripheral or a central cue. ISR occurred across these manipulations: saccade latency was consistently increased for movements to the immediately previously fixated location. Latency distributions from individual observers were fit with a Linear Ballistic Accumulator model. ISR was best accounted for as a change in the accumulation rate. We suggest this parameter represents the overall desirability of a particular course of action, the evidence for which may be derived from a variety of sensory and non-sensory sources.     

Intentionality,Cognitive Integration and the Continuity Thesis

Naturalistic philosophers ought to think that the mind is continuous with the rest of the world and should not, therefore, be surprised by the findings of the extended mind, cognitive integration and enactivism. Not everyone is convinced that all mental phenomena are continuous with the rest of the world. For example, intentionality is often formulated in a way that makes the mind discontinuous with the rest of the world. This is a consequence of Brentano’s formulation of intentionality, I suggest, and can be overcome by revealing that the concept of intentional directedness as he receives it from the Scholastics is quite consistent with the continuity thesis. It is only when intentional directedness is conjoined with intentional inexistence that intentionality and content are consistent with a discontinuity thesis (such as Brentano’s thesis). This makes room to develop an account of intentional directedness that is consistent with the continuity thesis in the form of Peirce’s representational principle. I also argue against a form of the discontinuity thesis in the guise of the derived/underived content distinction. Having shown that intentionality is consistent with the continuity thesis I argue that we should focus on intentionality and representation as bodily enacted. I conclude that we would be better off focussing on representation and intentionality in action rather than giving abstract functional accounts of extended cognition.

Long-term ability to interpret facial expression after traumatic brain injury and its relation to social integration

There is considerable evidence that individuals with traumatic brain injury (TBI) experience problems interpreting the emotional state of others. However, the functional implications of these changes have not been fully investigated. A study of 13 individuals with severe TBI and an equal number of matched controls found that TBI participants had significantly more difficulty interpreting facial expression and matching emotions to social situations. A significant relationship was also established between social integration and ability to interpret facial expression for TBI participants. These results support the inclusion of therapy targeting this area within rehabilitation programs for individuals with TBI.     

Gesture and metaphor comprehension: Electrophysiological evidence of cross-modal coordination by audiovisual stimulation

In recent years, studies have suggested that gestures influence comprehension of linguistic expressions, for example, eliciting an N400 component in response to a speech/gesture mismatch. In this paper, we investigate the role of gestural information in the understanding of metaphors. Event related potentials (ERPs) were recorded while participants viewed video clips of an actor uttering metaphorical expressions and producing bodily gestures that were congruent or incongruent with the metaphorical meaning of such expressions. This modality of stimuli presentation allows a more ecological approach to meaning integration. When ERPs were calculated using gesture stroke as time-lock event, gesture incongruity with metaphorical expression modulated the amplitude of the N400 and of the late positive complex (LPC). This suggests that gestural and speech information are combined online to make sense of the interlocutor’s linguistic production in an early stage of metaphor comprehension. Our data favor the idea that meaning construction is globally integrative and highly context-sensitive.     

汉英语义通达过程的事件相关电位研究

采用事件相关电位(ERP)技术对双语表征进行了探索。实验考察了句末词呈现之后500ms内英汉两种语言的语言内和语言间语义整合在语义一致和语义不一致两种条件下的P190和N400的潜伏期和波幅。结果显示,P190具有语言的形式加工效应,这种效应在汉英两种语言加工中有明显差异;而N400具有语义加工效应,汉英两种语言的N400模式相同。结果表明双话者两种语言的形态是分别表征的,而语义是共同表征的。     

基于组织的自尊的情境化与适用性

基于组织的自尊(OBSE)是组织情境下个人对自身能力和价值的评价, 对员工的工作态度、行为和绩效有重要的影响。在回顾最近研究的基础上, 总结了基于组织的自尊的情境化测量与结构。在整合现有相关研究和理论的基础上, 构建了基于组织的自尊情境化研究的法理性框架。针对国内外基于组织的自尊研究的差异, 结合中国情境的特殊性, 对“基于组织的自尊”概念在中国情境下语义差异、语义等值和情境适用性进行了讨论。最后, 对基于组织的自尊未来的情境化研究以及在中国情境下的发展进行了展望。     

Cardiac-somatic integration: An index of visual attention

Eighteen 15-week-old, normal full-term infants were presented with photographic slides of a human facial expression. The infant's heart rate, body movement, and visual attention were recorded simultaneously. The results showed that heart rate and body movement were significantly correlated during visual attention but not during inattention. Both heart rate and body movement decelerated significantly when the infants visually attended to the target stimulus. The results are discussed with reference to cardiac-somatic integration in early infancy and its implication as a possible index of attention.
