This 5-year longitudinal study investigated advanced theory-of-mind (AToM) development in 161 German 5- to 10-year-olds (89 females, 72 males). Core aspects of AToM developed nonlinearly, with children reaching a milestone at the age of 7 years, around when they attained the conceptual insight that mental states can be recursive. In late elementary school, a multicomponent battery was used. Performance on many aspects of AToM was predicted by information-processing skills (intelligence and language at 6 years), but not by the age when children acquired the basic conceptual insight; only some naturalistic, social-interpretative tasks were correlated with children’s age at acquisition. This study documents significant developmental progressions in middle-childhood AToM and suggests that different mechanisms may underlie diverse aspects of social cognition. 相似文献

An important part of children's social and cognitive development is their understanding that people are psychological beings with internal, mental states including desire, intention, perception, and belief. A full understanding of people as psychological beings requires a representational theory of mind (ToM), which is an understanding that mental states can faithfully represent reality, or misrepresent reality. For the last 35 years, researchers have relied on false-belief tasks as the gold standard to test children's understanding that beliefs can misrepresent reality. In false-belief tasks, children are asked to reason about the behavior of agents who have false beliefs about situations. Although a large body of evidence indicates that most children pass false-belief tasks by the end of the preschool years, the evidence we present in this monograph suggests that most children do not understand false beliefs or, surprisingly, even true beliefs until middle childhood. We argue that young children pass false-belief tasks without understanding false beliefs by using perceptual access reasoning (PAR). With PAR, children understand that seeing leads to knowing in the moment, but not that knowing also arises from thinking or persists as memory and belief after the situation changes. By the same token, PAR leads children to fail true-belief tasks. PAR theory can account for performance on other traditional tests of representational ToM and related tasks, and can account for the factors that have been found to correlate with or affect both true- and false-belief performance. The theory provides a new laboratory measure which we label the belief understanding scale (BUS). This scale can distinguish between a child who is operating with PAR versus a child who is understanding beliefs. This scale provides a method needed to allow the study of the development of representational ToM. In this monograph, we report the outcome of the tests that we have conducted of predictions generated by PAR theory. The findings demonstrated signature PAR limitations in reasoning about the mind during the ages when children are hypothesized to be using PAR. In Chapter II, secondary analyses of the published true-belief literature revealed that children failed several types of true-belief tasks. Chapters III through IX describe new empirical data collected across multiple studies between 2003 and 2014 from 580 children aged 4–7 years, as well as from a small sample of 14 adults. Participants were recruited from the Phoenix, Arizona metropolitan area. All participants were native English-speakers. Children were recruited from university-sponsored and community preschools and daycare centers, and from hospital maternity wards. Adults were university students who participated to partially fulfill course requirements for research participation. Sociometric data were collected only in Chapter IX, and are fully reported there. In Chapter III, minor alterations in task procedures produced wide variations in children's performance in 3-option false-belief tasks. In Chapter IV, we report findings which show that the developmental lag between children's understanding ignorance and understanding false belief is longer than the lag reported in previous studies. In Chapter V, children did not distinguish between agents who have false beliefs versus agents who have no beliefs. In Chapter VI, findings showed that children found it no easier to reason about true beliefs than to reason about false beliefs. In Chapter VII, when children were asked to justify their correct answers in false-belief tasks, they did not reference agents’ false beliefs. Similarly, in Chapter VIII, when children were asked to explain agents’ actions in false-belief tasks, they did not reference agents’ false beliefs. In Chapter IX, children who were identified as using PAR differed from children who understood beliefs along three dimensions—in levels of social development, inhibitory control, and kindergarten adjustment. Although the findings need replication and additional studies of alternative interpretations, the collection of results reported in this monograph challenges the prevailing view that representational ToM is in place by the end of the preschool years. Furthermore, the pattern of findings is consistent with the proposal that PAR is the developmental precursor of representational ToM. The current findings also raise questions about claims that infants and toddlers demonstrate ToM-related abilities, and that representational ToM is innate. 相似文献

In 2014–2015 and 2015–2016, a metropolitan school system in the southern United States embarked on a unique mission to improve the quality of its public prekindergarten programs through a partnership with a group of developmental researchers in an iterative, data‐based venture. Data on 407 children in Year 1 and 433 in Year 2 (who were enrolled in 26 classrooms and extensively observed) are presented from the first 2 years of the ongoing partnership. All children were 4 years of age. Variability in classroom practices, measured empirically, and variability in child outcomes provided the means to examine the relations between children's gains in academic and social‐emotional areas and major areas of classroom practices. Lessons learned, the eight identified significant practices, implications, and next steps in the partnership are addressed. 相似文献

Cognitive test anxiety is a considerable barrier to academic success. The control value theory of achievement emotions suggests emotions within academic situations—including test‐anxious responses—follow from control and value appraisals. Furthermore, the control value theory suggests a multitude of individual‐level factors that influence appraisals. However, few investigations have explored the interactive influence of enduring personality traits and control and value appraisals on the experience of cognitive test anxiety. The current study was designed to explore the relationship among openness to experience, neuroticism, conscientiousness, control and value appraisals, and cognitive test anxiety. Participants (N = 481) completed the Big Five Inventory, the Motivated Strategies for Learning Questionnaire, and the Cognitive Test Anxiety Scale‐Short Form. Using exploratory structural equation modeling, we demonstrated that value and control appraisals were important predictors of cognitive test anxiety. Furthermore, results indicated that openness to experience was a positive predictor of value appraisals. Finally, results indicated that higher levels of control appraisals were associated with higher levels of conscientiousness and openness to experience and lower levels of neuroticism. These findings have important implications for our understanding of the determinants of cognitive test anxiety and have implications for efforts designed to identify test‐anxious students. 相似文献
