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

Theory of mind and self-control: more than a common problem of inhibition   总被引:14,自引:0,他引:14

This study tested the theory that advances on theory-of-mind tasks and on executive function tasks show a strong correlation because the typically used theory-of-mind tasks pose the same executive demands. In Experiment 1 with fifty-six 3- to 6-year-old children, performance on the dimensional change card-sorting task as an executive function task was correlated with performance on the usual false-belief prediction task, r = .65, and the false-belief explanation task, r = .65, as measures of theory-of-mind development. Because the explanation version of the false-belief test is supposed to be free of the alleged executive demands inherent in the prediction version, the equally strong correlation with the executive function task suggests that this correlation cannot be due to common executive demands. In Experiment 2, the basic finding of Experiment 1 was replicated on another sample of 73 children, ages 3 to 5.5 years. The need for new theories to explain the developmental link between theory of mind and executive function development is discussed, and some existing candidates are evaluated.  相似文献

Our aim in this study was to investigate whether previous findings pointing to a delay in deaf children's theory of mind development are replicated when linguistic demands placed on the deaf child are minimized in a nonverbal version of standard false-belief tasks. Twenty-four prelingually deaf, orally trained children born of hearing parents were tested with both a verbal and a nonverbal version of a false-belief task. Neither the younger (range: 4 years 7 months-6 years 5 months) nor the older (range: 6 years 9 months-11 years 11 months) children of the final sample of 21 children performed above chance in the verbal task. The nonverbal task significantly facilitated performance in children of all ages. Despite this facilitation, we observed a developmental delay: only the older group performed significantly above chance in the nonverbal false-belief task, even though the younger children were at the average age when hearing children normally pass standard false-belief tests. We discuss these findings in light of the hypothesis that language development and conversational competence are crucial to the acquisition of a theory of mind.  相似文献

Theory-of-mind concepts in children with deafness, autism, and normal development (N = 154) were examined in three experiments using a set of standard inferential false-belief tasks and matched sets of tasks involving false drawings. Results of all three experiments replicated previously published findings by showing that primary school children with deafness or autism, aged 6 to 13 years, scored significantly lower than normal-developing 4-year-old preschoolers on standard misleading-container and unseen-change tests of false-belief understanding. Furthermore, deaf and autistic children generally scored higher on drawing-based tests than on corresponding standard tests and, on the most challenging of the false-drawing tests in Experiment 2, they significantly outperformed the normal-developing preschoolers by clearly understanding their own false intentions and another person's false beliefs about an actively misleading drawing. In Experiment 3, preschoolers outperformed older deaf and autistic children on standard tasks, but did less well on a task that required the drawing of a false belief. Methodological factors could not fully explain the findings, but early social and conversational experiences in the family were deemed likely contributors.  相似文献

Minds, modules, and meta-analysis   总被引:5,自引:0,他引:5  
Wellman and colleagues' meta-analysis of performance on the false-belief task is methodologically useful, but it does not lead to any theoretical progress concerning the nature of the mechanisms that underlie the existence and development of "theory of mind." In particular, the results of this meta-analysis are perfectly compatible with "early competence" accounts that posit a specific, innate, and possibly modular basis for theory of mind. The arguments presented by Wellman and colleagues against such views stem not from their meta-analytic data, but from mistaken assumptions regarding the requirements of such theories (e.g., that there exist manipulations that improve performance only, or to a greater degree, in young children). Contrary to what Wellman and colleagues claim, their meta-analysis, while consistent with conceptual change, does not lend any new support for such theories.  相似文献

The focus of the present study is on the developmental antecedents of domain-general experimentation skills. We hypothesized that false-belief understanding would predict the ability to distinguish a conclusive from an inconclusive experiment. We conducted a longitudinal study with two assessment points (t1 and t2) to investigate this hypothesis. As language, executive functioning, working memory, and intelligence have been discussed as potential influencing factors in theory of mind and scientific reasoning development, we included measures of these abilities as control variables. We recruited 161 preschool children (73 girls and 88 boys); we administered a false-belief task, an experimentation task, and the control variables at t1 when the children were 4 years old. We repeated the false-belief and experimentation tasks at t2 when the children were 5 years old. Our results show that children who solved the false-belief task correctly at age 4 were more likely to solve the experimentation task correctly at age 5, but not vice versa, even after controlling for the influence of language, executive functioning, working memory, and intelligence. The implications of these results on theories about the development of scientific reasoning and for science education concepts for young children are briefly discussed.  相似文献

Individual differences in young children's social cognition were examined in 128 urban preschoolers from a wide range of backgrounds. comprehensive assessments were made of children's false-belief understanding, emotion understanding, language abilities, and family background information was collected via parent interview. Individual differences in children's understanding of false-belief and emotion were associated with differences in language ability and with certain aspects of family background, in particular, parental occupational class and mothers' education. The number of siblings that children had did not relate to their social cognition. Individual differences in false-belief and emotion understanding were correlated, but these domains did not contribute to each other independently of age, language ability, and family background. In fact, variance in family background only contributed uniquely to false-belief understanding. The results suggest that family background has a significant impact on the development of theory of mind. The findings also suggest that understanding of false-belief and understanding of emotion may be distinct aspects of social cognition in young children.  相似文献

The association between executive function (EF) and theory of mind (ToM) has been hotly debated for 20 years. Competing accounts focus on: task demands, conceptual overlap, or functional ties. Findings from this meta‐analytic review of 102 studies (representing 9,994 participants aged 3–6 years) indicate that the moderate association between EF and one key aspect of ToM, false belief understanding (FBU) is: (a) similar for children from different cultures, (b) largely consistent across distinct EF tasks, but varies across different types of false belief task, and (c) is asymmetric in that early individual differences in EF predict later variation in FBU but not vice versa. These findings support a hybrid emergence‐expression account and highlight new directions for research.  相似文献

Research suggests that young children may see a direct and one-way connection between facts about the world and epistemic mental states (e.g., belief). Conventions represent instances of active constructions of the mind that change facts about the world. As such, a mature understanding of convention would seem to present a strong challenge to children's simplified notions of epistemic relations. Three experiments assessed young children's abilities to track behavioral, representational, and truth aspects of conventions. In Experiment 1, 3- and 4-year-old children (N = 30) recognized that conventional stipulations would change people's behaviors. However, participants generally failed to understand how stipulations might affect representations. In Experiment 2, 3-, 5-, and 7-year-old children (N = 53) were asked to reason about the truth values of statements about pretenses and conventions. The two younger groups of children often confused the two types of states, whereas older children consistently judged that conventions, but not pretenses, changed reality. In Experiment 3, the same 3- and 5-year-olds (N = 42) participated in tasks assessing their understanding of representational diversity (e.g., false belief). In general, children's performance on false-belief and "false-convention" tasks did not differ, which suggests that conventions were understood as involving truth claims (as akin to beliefs about physical reality). Children's difficulties with the idea of conventional truth seems consistent with current accounts of developing theories of mind.  相似文献

Scaling of theory-of-mind tasks   总被引:13,自引:0,他引:13  
Two studies address the sequence of understandings evident in preschoolers' developing theory of mind. The first, preliminary study provides a meta-analysis of research comparing different types of mental state understandings (e.g., desires vs. beliefs, ignorance vs. false belief). The second, primary study tests a theory-of-mind scale for preschoolers. In this study 75 children (aged 2 years, 11 months to 6 years, 6 months) were tested on 7 tasks tapping different aspects of understanding persons' mental states. Responses formed a consistent developmental progression, where for most children if they passed a later item they passed all earlier items as well, as confirmed by Guttman and Rasch measurement model analyses.  相似文献

Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the variability across studies--including aspect of language ability assessed, type of false-belief task used, and direction of effect. The results indicate a moderate to large effect size overall that remains significant when age is controlled. Receptive vocabulary measures had weaker relations than measures of general language. Stronger effects were found from earlier language to later false belief than the reverse. Significant differences were not found among types of false-belief task.  相似文献

The construct validity of maternal mind-mindedness (MM) was investigated in the context of its relations with children's later understanding of mind. MM measures were obtained from infant-mother (N = 52) interactions at 6 months, and from maternal interviews at 48 months. Children's understanding of mind was assessed using theory of mind (ToM) tasks at 45 and 48 months, and a stream of consciousness (SoC) task at 55 months. One of the early MM measures--mothers' appropriate mind-related comments--was a positive independent predictor of: (a) MM at 48 months, and (b) ToM and SoC performance at 45 to 55 months. Path analyses suggested direct links between mothers' use of appropriate mind-related comments and children's later understanding of mind.  相似文献

Are children’s understanding of mental states (understanding of mind) related to their notating skills, that is, their ability to produce and read written marks to convey information about objects and number? Fifty-three preschoolers and kindergarteners were presented with a dictation task where they produced some written marks and were later asked to read them back. Understanding of mind was assessed using two tasks. Children’s name-writing and language skills were assessed as covariates. Children’s understanding of their own and other’s mental states was associated with their notating skills. Findings are discussed in light of the reciprocal writer-reader relation: keeping an audience in mind when writing and a writer in mind when reading. This reciprocal relation is central to writing and reading development.  相似文献

Emotion understanding develops rapidly in early childhood. Firstborn children (N = 231, 55% girls/45% boys, 86% White, 5% Black, 3% Asian, 4% Latinx, Mage = 29.92 months) were recruited into a longitudinal study from 2004 to 2008 in the United States and administered a series of tasks assessing eight components of young children's emotion understanding from ages 1 to 5. Cohort sequential analysis across three cohorts (1-, 2-, and 3-year-olds) demonstrated a progression of children's emotion understanding from basic emotion identification to an understanding of false-belief emotions, even after controlling for children's verbal ability. Emotion understanding scores were related to children's theory of mind and parent reports of empathy, but not emotional reactivity, providing evidence of both convergent and discriminant validity.  相似文献

Hindsight bias and developing theories of mind   总被引:1,自引:0,他引:1  
Although hindsight bias (the "I knew it all along" phenomenon) has been documented in adults, its development has not been investigated. This is despite the fact that hindsight bias errors closely resemble the errors children make on theory of mind (ToM) tasks. Two main goals of the present work were to (a) create a battery of hindsight tasks for preschoolers, and (b) assess the relation between children's performance on these and ToM tasks. In two experiments involving 144 preschoolers, 3-, 4-, and 5-year olds exhibited strong hindsight bias. Performance on hindsight and ToM tasks was significantly correlated independent of age, language ability, and inhibitory control. These findings contribute to a more comprehensive account of perspective taking across the lifespan.  相似文献

Using four traditional false-belief tasks, I investigated deaf children's age and expressive language skills in relation to their theory of mind development. The children's parents who signed reported on their own knowledge of a mental sign vocabulary. The results indicate age of the child to be strongly related to theory of mind development. Deaf children demonstrated an ability to pass the theory of mind assessment battery between the ages of 7 and 8 years, on average. In comparison, hearing children have consistently demonstrated the ability to perform such tasks between the ages of 4 and 5 years. Therefore, the results indicate deaf children are delayed by approximately 3 years in this cognitive developmental milestone. Expressive language skills of the children and sign language skills of the parents who signed were not found to be significantly related to the children's theory of mind development.  相似文献

Young children show significant changes in their mental-state understanding as marked by their performance on false-belief tasks. This study provides evidence for activity in the prefrontal cortex associated with the development of this ability. Event-related brain potentials (ERPs) were recorded as adults ( N  = 24) and 4-, 5-, and 6-year-old children ( N  = 44) reasoned about reality and the beliefs of characters in animated vignettes. In adults, a late slow wave (LSW), with a left-frontal scalp distribution, was associated with reasoning about beliefs. This LSW was also observed for children who could correctly reason about the characters' beliefs but not in children who failed false-belief questions. These findings have several implications, including support for the critical role of the prefrontal cortex for theory of mind development.  相似文献

Relations between an early interest in violent fantasy and children's social understanding, antisocial and emotional behavior, and interactions with friends were investigated in 40 "hard-to-manage" preschoolers and 40 control children matched for gender, age, and school and ethnic background. Children were filmed alone in a room with a friend, and tested on a battery of cognitive tests, including false-belief, executive function, and emotion understanding tasks. Teachers reported on their friendship quality. At age 6 years, the children's understanding of the emotional consequences of antisocial and prosocial actions was studied. The hard-to-manage group showed higher rates of violent fantasy; across both groups combined, violent fantasy was related to poor executive control and language ability, frequent antisocial behavior, displays of anger and refusal to help a friend, poor communication and coordination of play, more conflict with a friend, and less empathic moral sensibility 2 years later. The usefulness of a focus on the content of children's pretend play-in particular, violent fantasy-as a window on children's preoccupations is considered.  相似文献
