自闭症幼儿自主性共同注意的实验研究 总被引:3,自引:0,他引:3
为探索和发现自闭症幼儿的自主性共同注意的特征,以6名自闭症幼儿,以及在心理年龄与之匹配的弱智和正常儿童各6名作为研究对象,以实验和准实验的方法,进行此研究。同时还以秒为单位对实验过程与结果进行编码分析。结果表明,自闭症幼儿的自主性视觉方向所及目标物多于人,而人的目标中叉更多地锁定同伴而非教师。自闭症幼儿在唤起他人共同注意时多以“拉”和“抱”来替代指点行为。自主性共同注意的发生率与情绪有密切关系。 相似文献

The nature of joint attention (JA) engagement of 32 sibling pairs (M age older sibling = 55.21 months; M age younger sibling = 19.60 months) was assessed in a free play context. Relations among JA engagement states, both siblings' age, temperament, and language, and older sibling theory of mind were explored. The frequency of coordinated JA was related to features of temperament of both the younger siblings (emotionality) and the older siblings (activity level and sociability). Younger siblings' age was significantly related to siblings' engagement in coordinated JA, whereas the older siblings' age and theory of mind correlated with the frequency of passive JA engagement. Implications regarding the role of partner characteristics in young sibling JA interactions will be discussed. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

The authors investigated the extent to which the joint-attention behaviors of gaze following, social referencing, and object-directed imitation were related to each other and to infants' vocabulary development in a sample of 60 infants between the ages of 8 and 14 months. Joint-attention skills and vocabulary development were assessed in a laboratory setting. Split-half reliability analyses on the joint-attention measures indicated that the tasks reliably assessed infants' capabilities. In the main analysis, no significant correlations were found among the joint-attention behaviors except for a significant relationship between gaze following and the number of names in infants' productive vocabularies. The overall pattern of results did not replicate results of previous studies (e.g., M. Carpenter, K. Nagell, & M. Tomasello, 1998) that found relationships between various emerging joint-attention behaviors. 相似文献

ABSTRACT— Before social cognition there is joint processing of information about the attention of self and others. This joint attention requires the integrated activation of a distributed cortical network involving the anterior and posterior attention systems. In infancy, practice with the integrated activation of this distributed attention network is a major contributor to the development of social cognition. Thus, the functional neuroanatomies of social cognition and the anterior–posterior attention systems have much in common. These propositions have implications for understanding joint attention, social cognition, and autism. 相似文献

A multiple baseline design across 3 children with autism was used to assess the effects of prompting and social reinforcement to teach participants to respond to an adult's bid for joint attention and to initiate bids for joint attention. Participants were taught to respond to an adult's bid for joint attention by looking in the direction of an object at which the adult pointed, by making a comment about the object, and by looking back at the adult. Additional training and reinforcement were needed to teach the participants to initiate bids for joint attention. Findings are discussed in terms of the social relevance of teaching children with autism to respond to and initiate bids for joint attention. 相似文献

Social motivation—the psychobiological predisposition for social orienting, seeking social contact, and maintaining social interaction—manifests in early infancy and is hypothesized to be foundational for social communication development in typical and atypical populations. However, the lack of infant social-motivation measures has hindered delineation of associations between infant social motivation, other early-arising social abilities such as joint attention, and language outcomes. To investigate how infant social motivation contributes to joint attention and language, this study utilizes a mixed longitudinal sample of 741 infants at high (HL = 515) and low (LL = 226) likelihood for ASD. Using moderated nonlinear factor analysis (MNLFA), we incorporated items from parent-report measures to establish a novel latent factor model of infant social motivation that exhibits measurement invariance by age, sex, and familial ASD likelihood. We then examined developmental associations between 6- and 12-month social motivation, joint attention at 12–15 months, and language at 24 months of age. On average, greater social-motivation growth from 6–12 months was associated with greater initiating joint attention (IJA) and trend-level increases in sophistication of responding to joint attention (RJA). IJA and RJA were both positively associated with 24-month language abilities. There were no additional associations between social motivation and future language in our path model. These findings substantiate a novel, theoretically driven approach to modeling social motivation and suggest a developmental cascade through which social motivation impacts other foundational skills. These findings have implications for the timing and nature of intervention targets to support social communication development in infancy.
Highlights
- We describe a novel, theoretically based model of infant social motivation wherein multiple parent-reported indicators contribute to a unitary latent social-motivation factor.
- Analyses revealed social-motivation factor scores exhibited measurement invariance for a longitudinal sample of infants at high and low familial ASD likelihood.
- Social-motivation growth from ages 6–12 months is associated with better 12−15-month joint attention abilities, which in turn are associated with greater 24-month language skills.
- Findings inform timing and targets of potential interventions to support healthy social communication in the first year of life.

Teasing requires the ability to understand intention, nonliteral communication, pretense, and social context. Children with autism experience difficulty with such skills, and consequently, are expected to have difficulty with teasing. To better understand teasing concepts and behaviors, children with autism, their parents, and age and Verbal-IQ-matched comparison children and parents described concepts and experiences of teasing and engaged in a parent–child teasing interaction. The teasing of children with autism was less playful and provocative and focused less on social norms than that of comparison children. Similarly, parents of children with autism teased in less playful ways. Scores on a theory of mind task accounted for several of the observed differences. Discussion focused on the importance of understanding social context and playful behavior during teasing. 相似文献

Evidence of Poor Planning in Children with Attention Deficits 总被引:1,自引:0,他引:1

This study examined the planning performance of children with attention deficits, and also investigated the possible interactions
between inattention and anxiety in the performance of executive function tasks. A group of 98 children (grades 4 and 6), derived
from an initial group of 550, were assigned to an attention difficulties group (AD) and a control group (n = 49 each) based on their scores on a variety of cognitive attention measures and teacher scales of attention and hyperactivity.
The two groups were matched on age, gender, parental education, non-verbal and verbal ability. They were compared on Crack-the-Code
(C-t-C) action-planning task, embedded and ambiguous figures and Theory of Mind tasks. Analyses indicated that the failure
of AD children on cognitive performance measures is linked to planning impairments. The co-occurrence of anxiety, in turn,
did not interact with inattention to affect planning performance differentially. Implications of these findings for the current
discussion about the cognitive and emotional processes underlying impaired performance among children with attention deficits
on executive control tasks are discussed. 相似文献

Young children appear not to grasp the independence between objective reality and subjective beliefs, as evidenced by their errors on false belief tasks. Whereas decades of research have examined children's developing understanding of the subjectivity of beliefs, however, almost no research has examined the other side of the issue: How do humans come to understand the objectivity of reality, and why is this understanding important? To help address this gap, this article proposes an evolutionary-developmental account of how the understanding that reality is objective may have emerged in human thinking. Three key steps are highlighted: (i) phylogenetic foundations in great ape competitive mindreading, (ii) ontogenetic foundations in preverbal infant joint attention, and (iii) key experiences of perspectival conflict in linguistic humans. Functionally, the concept of an objective reality facilitated collaborative reasoning and joint decision-making. To arrive at good joint decisions, individuals needed to recognize that both their own beliefs and others' beliefs could be wrong—with respect to the objective reality. 相似文献
