Infants' Physical World

Abstract— Investigations of infants' physical world over the past 20 years have revealed two main findings. First, even very young infants possess expectations about physical events. Second, these expectations undergo significant developments during the first year of life, as infants form event categories, such as occlusion, containment, and covering events, and identify the variables relevant for predicting outcomes in each category. A new account of infants' physical reasoning integrates these findings. Predictions from the account are examined in change-blindness and teaching experiments.     

The Development of Infants' Spatial Categories

ABSTRACT— Early theories of how infants develop spatial concepts focused on the perceptual and cognitive abilities that contribute to this ability. More recent research, however, has centered on whether experience with spatial language might also play a role. The present article reviews how infants learn to form spatial categories, outlining the perceptual and cognitive abilities that drive this learning, and examines the role played by spatial language. I argue that infants' spatial concepts initially are the result of nonlinguistic perceptual and cognitive abilities, but that, as infants build a spatial lexicon, spatial language becomes an important tool in the spatial categories infants learn to form.     

爬行经验与婴儿空间认知能力的发展

本研究采用“A非B”时间延搁测验对34名9-12个月缨儿的爬行经验与其空间认知能力发展的关系进行了研究。协方差分析表明,婴儿的爬行经验对其在“A非B”延搁任务中表现出来的空间认知能力有显著的主效应,而年龄的效应不明显;进一步分析显示,爬行经验7周以内的婴儿与爬行经验10周以上的婴儿空间认知能力发展水平差异显著。本研究说明,爬行经验与婴儿在“A非B”延搁任务上表现出来的空间认知能力发展有密切的关系。     

Folk psychology’ is not folk psychology

This paper disputes the claim that our understanding of others is enabled by a commonsense or ‘folk’ psychology, whose ‘core’ involves the attribution of intentional states in order to predict and explain behaviour. I argue that interpersonal understanding is seldom, if ever, a matter of two people assigning intentional states to each other but emerges out of a context of interaction between them. Self and other form a coupled system rather than two wholly separate entities equipped with an internalised capacity to assign mental states to the other. This applies even in those instances where one might seem to adopt a ‘detached’ perspective towards others. Thus ‘folk psychology’, as commonly construed, is not folk psychology.     

Self-Knowledge and the ‘Inner Eye’

Mutual perceptual knowledge is a prevalent feature of our everyday lives, yet appears to be exceptionally difficult to characterise in an acceptable way. This paper argues for a renewed understanding of Stephen Schiffer's iterative approach to mutual knowledge, according to which mutual knowledge requires an infinite number of overlapping, embedded mental states. It is argued that the charge of ‘psychological implausibility’ that normally accompanies discussion of this approach can be offset by identifying mutual knowledge, not with the infinite iterations themselves, but with the finite base which Schiffer proves is capable of generating those iterations. An understanding of this finite base as a primitive, relational property holding between two or more people, allows us to understand the iterations as an implicit and ‘harmless’ intrapersonal feature of what is an interpersonal phenomenon. The paper concludes by relating the account to joint attention in infant interaction.     

The Cross-Modal Coordination of Interpersonal Timing: Six-Week-Olds Infants' Gaze with Adults' Vocal Behavior

The purpose of this study was to examine the hypothesis that 6-week-old infants are capable of coordinated interpersonal timing within social interactions. Coordinated interpersonal timing refers to changes in the timing of one individual's behavior as a function of the timing of another individual's behavior. Each of 45, first-born 6-week-old infants interacted with his or her mother and a stranger for a total of 14 minutes. The interactions were videotaped and coded for the gaze behavior of the infants and the vocal behavior of the mothers and strangers. Time-series regression analyses were used to assess the extent to which the timing of each of the infants' gazes was coordinated with the timing of the adults' vocal behavior. The results revealed that (a) coordinated timing occurs between infants and their mothers and between infants and strangers as early as when infants are 6 weeks old, and (b) strangers coordinated the timing of their pauses with the infants to a greater extent than did mothers. The findings are discussed in terms of the role of temporal sensitivity in social interaction.     

脑功能定位在社会认知研究中的作用及其启示

本文阐述了脑功能定位的具体技术及其与社会心理现象相结合的心理神经模型。这种结合的趋势有助于促进神经科学和社会心理学的发展,有助于解释社会心理现象中固有的一些具体问题。同时,由于社会心理现象的复杂性,因此并不一定都适合直接进行脑功能定位。     

理解私人意图与交际意图的ERP证据

已有的意图理解神经成像研究大多关注理解单一个体私人意图的脑功能定位, 而较少涉及两个或更多人的社会性交际意图, 大脑区分私人意图和交际意图的动态时间过程尚不清楚。本研究记录了16名健康被试理解三种不同意图任务时的脑电成分。三种意图分别为: 1)私人意图; 2)交际意图; 3)物理意图。电生理学结果表明在大脑顶区, 私人意图的N250的峰值显著大于交际意图和物理意图。在晚期阶段(300~600 ms), 交际意图的晚期正成分(LPC)的平均波幅要显著大于私人意图和物理意图。在400~600 ms时, 私人意图的LPC的平均波幅要显著大于物理意图。本研究为理解私人意图和交际意图的动态加工过程提供了神经电生理学的初步证据。     

材料生态性和性别因素对理解友好与敌对意图的影响

为考察材料生态性、被试性别和角色性别对理解友好与敌对意图的影响,分析了100名被试观察由2名男性或2名女性表演的三类互动意图的照片或卡通时的正确率和反应时。结果：理解真实人物的正确率高于虚拟角色;女性被试理解虚拟角色的反应时长于真实人物,而男性被试却未出现材料生态性差异;理解男性角色敌对意图的反应时短于女性角色的,而理解友好意图时却未出现角色性别差异。研究为负性偏向等理论提供实证证据,揭示材料生态性、角色性别对理解友好和敌对意图的影响机制。     

Developing a Cultural Theory of Mind: The CIAO Approach

The study of children's knowledge about minds is an extremely active area of developmental psychology. This article discusses the reach of this research and the theoretical views guiding it. It then presents some cultural variations (within the United States) in behavior explanation and explains the relevance of that variation to developmental theory. A theory ofearly mind reading that is presented incorporates culture, introspection, analogy, and ontogeny (CIAO).     

Infants' sensitivity to arbitrary object-odor pairings

The ability of 4-month-old infants to learn the arbitrary relationship between an object and a distinctive odor was assessed. Infants were familiarized with two objects while one of them was paired with a cherry odor. Results indicated that only female subjects showed evidence of matching. They increased their looking to the target object in the presence of the odor but not in the absence of the odor, relative to baseline levels.     

On the Representation of Strong and Weak Attitudes About Policy in Memory

A priming paradigm was used to explore the representation of attitudes about government policies in memory. Participants performed pairs of tasks in quick succession. The focal tasks involved evaluating a policy or thinking of one of its consequences. The results showed that thinking of a consequence of a policy speeded up its subsequent evaluation, regardless of whether the participant held a strong or weak attitude about the policy. Evaluating the policy speeded up thinking of one of its consequences for strong attitudes but not for weak ones. In general, it took participants longer to think of a consequence of a policy than to evaluate it. The implications of these results for existing views of the representation of attitudes in memory are discussed.     

Infants' ability to connect gaze and emotional expression to intentional action

Four studies investigated whether and when infants connect information about an actor's affect and perception to their action. Arguably, this may be a crucial way in which infants come to recognize the intentional behaviors of others. In Study 1 an actor grasped one of two objects in a situation where cues from the actor's gaze and expression could serve to determine which object would be grasped, specifically the actor first looked at and emoted positively about one object but not the other. Twelve-month-olds, but not 8-month-olds, recognized that the actor was likely to grasp the object which she had visually regarded with positive affect. Studies 2, 3, and 4 replicated the main finding from Study 1 with 12- and 14-month-olds and included several contrasting conditions and controls. These studies provide evidence that the ability to use information about an adult's direction of gaze and emotional expression to predict action is both present, and developing at the end of the first year of life.     

The Level of Detail in Infants' Word Learning

ABSTRACT— This article summarizes recent findings on infant word learning and recognition. Infants initially store very detailed representations of words, including details that are not truly necessary for word recognition. As they are exposed to more varied productions of words, they develop more sophisticated knowledge about which details are important, and streamline their representations, allowing them to better recognize words across different contexts, speakers, and environments.     

Own and Others' Prior Experiences Influence Children's Imitation of Causal Acts

Young children learn from others' examples, and they do so selectively. We examine whether the efficacy of prior experiences influences children's imitation. Thirty-six-month-olds had initial experience on a causal learning task either by performing the task themselves or by watching an adult perform it. The nature of the experience was manipulated such that the actor had either an easy or a difficult experience completing the task. Next, a second adult demonstrated an innovative technique for completing it. Children who had a difficult first-person experience, and those who had witnessed another person having difficulty, were significantly more likely to adopt and imitate the adult's innovation than those who had or witnessed an easy experience. Children who observed another were also more likely to imitate than were those who had the initial experience themselves. Imitation is influenced by prior experience, both when it is obtained through one's own hands-on motor manipulation and when it derives from observing the acts of others.     

意图明确条件下小学儿童对说谎的理解与道德评价

本研究对 7、9和 1 1岁儿童进行了说谎概念的理解与道德评价的研究。研究的目的是想揭示小学儿童在说话者意图明显的条件下对说谎的理解和道德评价中的认知特点。结果发现 ,“事实”因素是影响儿童理解“说谎”的决定因素 ;对说谎 /说真话的道德评价则不同于理解 ,至少到 9岁时 ,儿童的评价依据已由“事实”因素开始转向考虑说话者内在心理过程的“交往目的”因素 ,“情景”因素对道德评价也有一定的作用。     

Infants’ coding of location in continuous space

The ability to code location in continuous space is fundamental to spatial behavior. Existing evidence indicates a robust ability for such coding by 12 months, but systematic evidence on earlier origins is lacking. A series of studies investigated 5-month-olds’ ability to code the location of an object hidden in a sandbox, using a looking-time paradigm. In Experiment 1, after familiarization with a hiding-and-finding sequence at one location, infants looked longer at an object being disclosed from a location 12 inches (30 cm) away than at an object emerging from the hiding location, showing they were able to code location in continuous space. In Experiment 2, infants reacted with greater looking when objects emerged from locations 8 inches (20 cm) away from the hiding location, showing that location coding was more finely grained than could be inferred based on the first study. In Experiment 3, infants were familiarized with an object shown in hiding-and-finding sequences at two different locations. Infants looked longer at objects emerging 12 inches (30 cm) away from the most recent hiding location than to emergence from the other location, showing that infants could code location even when events had previously occurred at each location. In Experiment 4, after familiarization with two objects with different shapes, colors, and sounding characteristics, shown in hiding-and-finding sequences in two locations, infants reacted to location violations as they had in Experiment 3. However, they did not react to object violations, that is, events in which the wrong object emerged from a hiding location. Experiment 5 also found no effect of object violation, even when the infants initially saw the two objects side by side. Spatiotemporal characteristics may play a more central role in early object individuation than they do later, although further study is required.
