The Efficacy of Toddler-Parent Psychotherapy for Fostering Cognitive Development in Offspring of Depressed Mothers

The efficacy of Toddler-Parent Psychotherapy (TPP) as a preventive intervention for fostering cognitive development in the offspring of depressed mothers was evaluated. Mothers with major depressive disorder and their toddlers were randomly assigned to TPP (n = 43) or to a nonintervention group (n = 54) and compared to a control group (n = 61) of women with no current or past mental disorder. At baseline (age 20 months), the groups did not differ on the Bayley Mental Development Index. At post-intervention follow-up (age 3 years), a relative decline in IQ was found in the depressed nonintervention group, whereas the depressed intervention and the normal control groups continued to be equivalent, with higher WPPSI-R Full Scale and Verbal IQs. The worst outcome was found among nonintervention children whose mothers had subsequent depressive episodes. The results confirm the developmental risks faced by offspring of depressed mothers and support the efficacy of the preventive intervention in safeguarding successful cognitive development in at-risk youngsters.     

Current and Past Maternal Depression, Maternal Interaction Behaviors, and Children’s Externalizing and Internalizing Symptoms

Relations among past maternal depressive disorder, current depressive symptoms, current maternal interaction behaviors, and children's adjustment were examined in a sample of 204 women and their young adolescent offspring (mean age = 11.86, SD = 0.55). Mothers either had (n = 157) or had not (n = 57) experienced at least one depressive disorder during the child's life. Mothers and children participated in a problem-solving task, video-taped for later coding. Mothers with current depressive symptoms and those with histories of chronic/severe depressive disorders displayed fewer positive behaviors toward their children; mothers with current depressive symptoms also showed more negative behaviors with their children. The relation between mothers' depression history and their behavior during the interaction with their child was partially mediated by mothers' current mood state. Moreover, high levels of maternal negativity and low levels of positivity during the problem-solving task were related to children's externalizing problems. Maternal positivity partially mediated the relation between maternal depression and children's externalizing symptoms. These findings highlight the importance of providing parenting interventions for depressed mothers.     

Implicit and explicit false belief development in preschool children

The ability to represent the mental states of other agents is referred to as Theory of Mind (ToM). A developmental breakthrough in ToM consists of understanding that others can have false beliefs about the world. Recently, infants younger than 2 years of age have been shown to pass novel implicit false belief tasks. However, the processes underlying these tasks and their relation to later‐developing explicit false belief understanding, as well as to other cognitive abilities, are not yet understood. Here, we study a battery of implicit and explicit false belief tasks in 3‐ and 4‐year‐old children, relating their performance to linguistic abilities and executive functions. The present data show a significant developmental change from failing explicit false belief tasks at 3 years of age to passing them at the age of 4, while both age groups pass implicit false belief tasks. This differential developmental trajectory is reflected by the finding that explicit and implicit false belief tasks do not correlate. Further, we demonstrate that explicit false belief tasks correlate with syntactic and executive functions, whereas implicit false belief tasks do not. The study thus indicates that the processes underlying implicit false belief tasks are different from later‐developing explicit false belief understanding. Moreover, our results speak for a critical role of syntactic and executive functions for passing standard explicit false belief tasks in contrast to implicit tasks.     

A lag between understanding false belief and emotion attribution in young children: Relationships with linguistic ability and mothers' mental‐state language

This study examines the contribution of children's linguistic ability and mothers' use of mental‐state language to young children's understanding of false belief and their subsequent ability to make belief‐based emotion attributions. In Experiment 1, children (N = 51) were given three belief‐based emotion‐attribution tasks. A standard task in which the protagonist was a story character and the emotional outcomes were imagined, and two videos in which the story protagonist was a real infant and the emotional outcomes were observable (high and low expressed emotion conditions). Children's verbal ability (semantic competence) was also measured. In Experiment 2, children (N = 75) were given two belief‐based emotion tasks: the standard story task and the high expressed emotion video. In addition, children's verbal ability (syntactic competence) and mothers' use of mental‐state attributes when describing their children were also measured. The results showed that: (1) the lag between understanding false belief and emotion attribution was a stable feature of children's reasoning across the three tests; and (2) children who were more linguistically advanced and whose mothers' described them in more mentalistic terms were more likely to understand the association between false belief and emotion. The findings underline the continuing importance of verbal ability and linguistic input for children's developing theory‐of‐mind understanding, even after they display an understanding of false belief.     

Sibling conflict and theory of mind

This study examined conflicts between siblings in an attempt to identify variables that are related to false‐belief understanding. The variables investigated were children's use of mental state terms and specific types of arguments (Slomkowski & Dunn, 1992) that occurred during conflict episodes. Twenty‐two children between 3 and 5 years of age were administered eight false‐belief tasks and were also videotaped while playing with an older sibling. Use of other‐oriented arguments by the target child was significantly associated with success on false‐belief tasks after controlling for age and general language ability. No use of argument was negatively related to performance on the false‐belief tasks after controlling for age and general language ability. Neither the use of self‐oriented arguments nor use of mental state terms was found to be associated with false‐belief performance. The findings indicate that specific features of sibling conflicts are related to children's developing false‐belief understanding.     

Reliability and generalizability of an acted-out false belief task in 3-year-olds

The current study tested the reliability and generalizability of a narrative act-out false belief task held to reveal Theory of Mind (ToM) competence at 3 years of age, before children pass verbal standard false belief tasks (the “Duplo task”; Rubio-Fernández & Geurts, 2013, Psychological Science). We conducted the task across two labs with methodologically improved matched control conditions. Further, we administered an analogue intensionality version to assess the scope of ToM competence in the Duplo task. 72 3-year-olds participated in a Duplo change-of-location task, a Duplo intensionality task, and half of them in a matched verbal standard change-of-location task, receiving either false belief or matched true belief scenarios. Children performed at chance in the false belief Duplo location change and intensionality tasks as well as in the standard false belief task. There were no differences to the standard task, and performance correlated across all three false belief tasks, revealing a rather unified competence and no task advantage. In the true belief conditions of both Duplo tasks, children performed at ceiling and significantly different from the false belief conditions, while they were at chance in the true belief condition of the standard task. The latter indicates that a pragmatic advantage of the Duplo task compared to the standard task holds only for the true belief scenarios. Our study shows that the Duplo task measures the same ToM competence as the standard task and rejects a notion of earlier false belief understanding on the group level in 3-year-old children.     

特定句法提示对3－4岁儿童错误信念理解的影响

False belief and emotion understanding in monozygotic twins,dizygotic twins and non-twin children

This study investigated the understanding of false belief and emotion in monozygotic (MZ) and same-sex dizygotic (DZ) twin pairs compared to non-twin children. Aged 3;9 to 5;1 years, the children (N=123) were administered three false belief and three emotion understanding tasks. Age, family socioeconomic status, mother's level of education and language abilities were controlled. Results showed no difference between the three groups in false belief understanding. On emotion tasks, non-twin children and DZ twins did not differ from each other, but they both performed better than MZ twins. Results are discussed in terms of the Peterson's (2000) variety hypothesis and suggest that the affective closeness experienced by MZ twins might interfere with their understanding of others’ emotions.     

Overgeneral autobiographical memory in children of depressed mothers

The goal of this study was to examine overgeneral autobiographical memory in a population at-risk for depression (i.e., children of depressed mothers). We predicted that children of depressed mothers would display less-specific memories than children of non-depressed mothers and that these results would be observed among children with no prior history of depression themselves. Participants in this study were children (age 8–14; 50% girls, 83% Caucasian) of mothers with (n = 103) or without (n = 120) a history of major depressive disorder during the child's life. Mothers' and children's diagnoses were confirmed with a diagnostic interview, and children completed the Autobiographical Memory Test and a measure of depressive symptoms. We found that children of depressed mothers, compared to children of non-depressed mothers, recalled less-specific memories in response to negative cue words but not positive cue words. Importantly, these results were maintained even when we statistically controlled for the influence of children's current depressive symptom levels and excluded children with currently depressed mothers. These results suggest that overgeneral autobiographical memory for negative events may serve as a marker of depression risk among high-risk children with no prior depression history.     

Biased processing of emotional information in girls at risk for depression

Researchers have documented that children of depressed mothers are at elevated risk for developing a depressive disorder themselves. There is currently little understanding, however, of what factors place these children at elevated risk. In the present study, the authors investigated whether never-disordered daughters whose mothers have experienced recurrent episodes of depression during their daughters' lifetime are characterized by biased processing of emotional information. Following a negative mood induction, participants completed an emotional-faces dot-probe task. Daughters at elevated risk for depression, but not control daughters of never-disordered mothers, selectively attended to negative facial expressions. In contrast, only control daughters selectively attended to positive facial expressions. These results provide support for cognitive vulnerability models of depression.     

Attributional style and self-control behavior in depressed and nondepressed children and their parents

Do the reformulated model of learned helplessness and the self-control model apply to clinically depressed children? Are the related cognitive patterns specific to depression? Are the cognitive deficits associated with depression learned from one's parents? To address these questions this investigation examined three groups of children (ages 8–12) and their parents: nonclinic (n =25),nondepressed clinic (n=22),and depressed clinic (n=15).Children were diagnosed depressed on the basis of Kiddie-SADS interview data. Depressed clinic children self-reported more depression, had a more depressive attributional style, and had more self-control problems. There were more depressed mothers in the clinic than in the nonclinic sample. Depressed clinic children had more depressed mothers than did nondepressed clinic children. There were no differences among the three groups of parents in their cognitive patterns. No relationship was found between the attributional style and self-control behavior of children and their parents.     

A Meadian account of social understanding: Taking a non-mentalistic approach to infant and verbal false belief understanding

Performance on false belief tasks has long been considered a key indicator of the development of social understanding in young children. We consider the enabling conditions for performing non-verbal and verbal false belief tasks as well as a typical developmental path toward false belief understanding. We argue that, in early ontogenesis, children anticipate the coordination of activity with others rather than read, probe, or reflectively engage with the psychological states of others. As linguistically mediated reflective thought emerges, children gradually become able to parse and isolate the myriad of incipient somatic, affective, and intentional responses that arise in any given moment. With reflective thought, children also begin to develop distinct and temporally coherent understandings about the minds of self and other. We provide an account of how the reflective thought that facilitates false belief understanding emerges. Our account focuses on a gradually developing refinement of social coordination and the shared perspectival understandings inherent in social coordination.     

Production of basic emotions by children with congenital blindness: Evidence for the embodiment of theory of mind

Children with congenital blindness are delayed in understanding other people's minds. The present study examined whether this delay was related to a more primitive form of inter‐subjectivity by which infants draw correspondence between parental mirroring of the infant's display and proprioceptive sensations. Twenty children with congenital blindness and 20 typically‐developing sighted children aged between 4 and 12 years were administered a series of tasks examining false belief and emotion understanding and production. The blind children scored lower on the false belief tasks and did not convey emotions facially to adult observers as accurately as sighted participants. The adults' ratings of the children's expressions were correlated with the children's scores on the false belief tasks. It is suggested that understanding people's minds might be anchored in primitive embodied forms of relatedness.     

Relations Among Preschool Children's Understanding of Visual Perspective Taking,False Belief,and Lying

This study investigated the relations among preschool children's ability to understand that other people see things differently than they do, that other people can believe things differently than the children know to be true, and that they can manipulate others' beliefs through intentional lying. Children between the ages of 3 and 5 were given tasks that tested their knowledge of Level 2 visual perspective taking, understanding of false belief, and the discriminative use of deceptive ploys. The Peabody Picture Vocabulary Test (PPVT-III) was administered as a measure of language proficiency. The children's scores on the three types of tasks were correlated with each other and with children's age, but not with scores on the PPVT-III. Most children either passed all the tasks or failed all the tasks. Regression analyses indicated that scores on visual perspective taking and false belief independently predicted each other, and scores on false belief and the discriminative use of deception independently predicted each other. The results provide evidence that advances in visual perspective taking, false belief understanding, and the discriminative use of deceptive ploys are developmentally related and occur in close synchrony.     

The accidental transgressor: morally-relevant theory of mind

To test young children’s false belief theory of mind in a morally relevant context, two experiments were conducted. In Experiment 1, children (N = 162) at 3.5, 5.5, and 7.5 years of age were administered three tasks: prototypic moral transgression task, false belief theory of mind task (ToM), and an “accidental transgressor” task, which measured a morally-relevant false belief theory of mind (MoToM). Children who did not pass false belief ToM were more likely to attribute negative intentions to an accidental transgressor than children who passed false belief ToM, and to use moral reasons when blaming the accidental transgressor. In Experiment 2, children (N = 46) who did not pass false belief ToM viewed it as more acceptable to punish the accidental transgressor than did participants who passed false belief ToM. Findings are discussed in light of research on the emergence of moral judgment and theory of mind.     

幼儿心理状态术语的运用与心理理论的发展

本研究目的在于探讨幼儿在假装游戏中心理状态术语的应用,以及与错误信念的理解是否存在相关并具有一定的发展特征。57名3—5岁的幼儿参加了实验。研究程序包括两类标准错误信念任务及假装游戏的拍摄、麦卡锡幼儿言语智力测验。结果发现：(1)幼儿的一般言语能力与错误信念的理解存在显著相关;(2)幼儿心理状态术语的使用存在情境差异,且随年龄的增长具有“指向愿望一指向信念”的维度特征;(3)在控制相关因素之后,幼儿错误信念的理解与心理状态术语的应用及其特定范畴(习惯用语)之间仍然存在显著相关;与“真正涉及心理状态”之间的相关不再显著。     

Cognitive processing of emotional information in depression, panic, and somatoform disorder

Emotional Stroop tasks (subliminal/supraliminal exposures), implicit memory tasks (tachistoscopic word identification), and explicit memory tasks (free recall after incidental learning) with 4 word types (physical threat, positive, negative, and neutral words) were administered to patients with major depressive disorder (n=30), panic disorder (n=33), somatoform disorder (n=25), and healthy control participants (n=33). On the Stroop task, panic patients showed subliminal interferences for physical threat and negative words, depressive patients showed supraliminal interferences for negative words, and somatoform patients showed supraliminal interferences for physical threat words. No patient groups demonstrated implicit memory biases. On the explicit memory task, depressive and panic patients showed memory biases for negative words; somatoform patients showed biases for physical threat words.

幼儿看图叙述中心理状态术语的使用与错误信念理解关系的短期跟踪研究

摘 要：为探明汉语儿童看图叙述中心理状态术语的应用及与错误信念理解能力的关系,并追踪二者相互作用的方向,本研究以101名3-5岁儿童为研究对象,纵向探查了前后相隔3个月的儿童看图叙述中心理状态术语使用情况和错误信念能力的发展状况,并从横向和纵向两个时间点分别探讨了心理状态术语的运用与错误信念理解的关系。结果表明：3-5岁儿童错误信念理解能力快速发展;儿童看图叙述中使用较多的愿望术语和情绪术语,信念术语应用相对较少,且认知词汇类型较少。控制了一般语言能力和年龄之后,仅在第一次测验上,情绪术语、信念术语仍然与同期及后期错误信念理解能力存在显著相关。     

外表真实区别、表征变化和错误信念的任务分析

自20世纪80年代以来,“心理理论”已成为发展心理学的研究热点和最活跃、最多产的领域。为了分析和比较“心理理论”的实验任务,该研究以济南市3所幼儿园中的233名3—6岁儿童为有效被试。进行了“意外转移。和“欺骗外表”两种心理理论实验任务。得出如下主要结论：(1)意外转移任务中内隐错误信念显著难于标准错误信念,易化错误信念与标准错误信念的难度不存在显著差异。(2)欺骗外表任务中外表真实区别难度显著低于表征变化和错误信念。(3)意外转移任务的错误信念显著难于欺骗外表任务的错误信念。
