多人交互同步记录技术在大脑神经活动测量中的应用*

多人交互同步记录是一种新技术,可以实现同时对多人的脑活动进行测量,现已被越来越多地应用到社会交互的研究中。本文从不同技术角度出发,回顾已经发表的有关多人交互同步记录的研究,从中可以了解不同的脑活动记录技术是如何被应用到各种实验范式中,以及人脑间是如何动态交互的。同时本文也对不同的多人交互同步记录技术的优缺点进行了比较。鉴于该方法的优势,其在未来的社会交互研究中具有广泛的应用前景。     

基因-环境交互作用理论模型及其检验方法

素质?压力模型、不同易感性模型和优势敏感性模型是当前有关基因?环境交互作用的三种代表性理论模型。素质?压力模型认为“近墨者黑”或“出淤泥而不染”, 优势反应敏感性模型认为“近朱者赤”, 而不同易感性模型则兼收并蓄, 认为某些个体近墨则黑, 近朱则赤。检验上述模型的现实有效性是当前基因?环境交互作用研究领域的热点问题之一。概观而言, 分组回归和分层回归是常用的传统检验方法, 显著性区域分析法和新参数回归模型法则是新近兴起的。未来研究需要进一步探索三种模型的领域特殊性、种族差异等问题, 检验这些模型的方法也有待改善。

Infants in group care: their interactions with professional caregivers and parents across the second year of life

Seventy children were observed during structured play with their primary professional caregivers and three peers in the child care center and with their primary caregiving parents at home at 15 and 23 months of age. The same structured play tasks were used in the two settings and the quality of the children's interactions with caregivers and parents was rated using the same 7-point scales. As expected, the quality of caregiver–child interactions significantly increased between 15 and 23 months. At 15 months, the quality of caregiver–child interactions was significantly lower than the quality of parent–child interactions, particularly with regard to caregiver supportive presence and respect for the child's autonomy. At 23 months, however, the quality of caregiver–child interactions was no longer lower and in some respects even higher than the quality of parent–child interactions. At both ages, the children expressed more negativity towards their parents than towards their professional caregivers.     

The “dual usage problem” in the explanations of “joint attention” and children’s socioemotional development: A reconceptualization

The term “joint attention”, which first gained currency in the early 1960s in studies of the development of language and symbolic thought, remains significant in the developmental literature. However, its meaning is unclear. A definitional problem exists similar to what Patterson [Patterson, M. L. (1982). A sequential functional model of nonverbal exchange. Psychological Review, 89, 231–249] described as the “dual usage” problem in the study of behaviour. The dual usage problem manifests when the behaviours of interest are used interchangeably with the function served by those behaviours. Similarly, the behaviours or skills that are taken to show joint attention are used interchangeably with the functions served by these behaviours. Scant attention is given to how the behaviours are generated and regulated and how they contribute to development. The purpose of the present position paper was: (1) to identify and illustrate the ways in which the behaviours and functions of joint attention have been confounded in the literature; (2) to provide a revised operationalization of joint attention incorporating the idea of Consummative Joint Attention, which is defined as a process variable that integrates these two theoretically different and complementary aspects of “joint attention;” and (3) to test this revised definition with evidence from a sample of hearing mothers and their 18- to 36-month-old hearing or deaf toddlers. We suggest that a reconceptualization and revised definition of joint attention as a process served by a particular sequence of complementary and well-timed events in the behaviour of mother–child interaction are particularly well-suited to testing joint attention as an early prelingual mechanism and to detecting early problems with psychosocial and adaptive development created by ineffective patterns of social interaction.

The tonal function of a task-irrelevant chord modulates speed of visual processing

Harmonic priming studies have provided evidence that musical expectations influence sung phoneme monitoring, with facilitated processing for phonemes sung on tonally related (expected) chords in comparison to less-related (less-expected) chords [Bigand, Tillmann, Poulin, D’Adamo, and Madurell (2001). The effect of harmonic context on phoneme monitoring in vocal music. Cognition, 81, B11–B20]. This tonal relatedness effect has suggested two interpretations: (a) processing of music and language interact at some level of processing; and (b) tonal functions of chords influence task performance via listeners’ attention. Our study investigated these hypotheses by exploring whether the effect of tonal relatedness extends to the processing of visually presented syllables (Experiments 1 and 2) and geometric forms (Experiments 3 and 4). For Experiments 1–4, visual target identification was faster when the musical background fulfilled listeners’ expectations (i.e., a related chord was played simultaneously). In Experiment 4, the addition of a baseline condition (i.e., without an established tonal center) further showed that the observed difference was due to a facilitation linked to the related chord and not to an inhibition or disruption caused by the less-related chord. This outcome suggests the influence of musical structures on attentional mechanisms and that these mechanisms are shared between auditory and visual modalities. The implications for research investigating neural correlates shared by music and language processing are discussed.     

The co-occurrence of multisensory competition and facilitation

Previous studies of multisensory integration have often stressed the beneficial effects that may arise when information concerning an event arrives via different sensory modalities at the same time, as, for example, exemplified by research on the redundant target effect (RTE). By contrast, studies of the Colavita visual dominance effect (e.g., [Colavita, F. B. (1974). Human sensory dominance. Perception & Psychophysics, 16, 409–412]) highlight the inhibitory consequences of the competition between signals presented simultaneously in different sensory modalities instead. Although both the RTE and the Colavita effect are thought to occur at early sensory levels and the stimulus conditions under which they are typically observed are very similar, the interplay between these two opposing behavioural phenomena (facilitation vs. competition) has yet to be addressed empirically. We hypothesized that the dissociation may reflect two of the fundamentally different ways in which humans can perceive concurrent auditory and visual stimuli. In Experiment 1, we demonstrated both multisensory facilitation (RTE) and the Colavita visual dominance effect using exactly the same audiovisual displays, by simply changing the task from a speeded detection task to a speeded modality discrimination task. Meanwhile, in Experiment 2, the participants exhibited multisensory facilitation when responding to visual targets and multisensory inhibition when responding to auditory targets while keeping the task constant. These results therefore indicate that both multisensory facilitation and inhibition can be demonstrated in reaction to the same bimodal event.     

Audience-contingent variation in action demonstrations for humans and computers

People may exhibit two kinds of modifications when demonstrating action for others: modifications to facilitate bottom-up, or sensory-based processing; and modifications to facilitate top-down, or knowledge-based processing. The current study examined actors' production of such modifications in action demonstrations for audiences that differed in their capacity for intentional reasoning. Actors' demonstrations of complex actions for a non-anthropomorphic computer system and for people (adult and toddler) were compared. Evidence was found for greater highlighting of top-down modifications in the demonstrations for the human audiences versus the computer audience. Conversely, participants highlighted simple perceptual modifications for the computer audience, producing more punctuated and wider ranging motions. This study suggests that people consider differences in their audiences when demonstrating action.
