From children's hands to adults' ears: gesture's role in the learning process

Children can express thoughts in gesture that they do not express in speech--they produce gesture-speech mismatches. Moreover, children who produce mismatches on a given task are particularly ready to learn that task. Gesture, then, is a tool that researchers can use to predict who will profit from instruction. But is gesture also useful to adults who must decide how to instruct a particular child? We asked 8 adults to instruct 38 third- and fourth-grade children individually in a math problem. We found that the adults offered more variable instruction to children who produced mismatches than to children who produced no mismatches--more different types of instructional strategies and more instructions that contained two different strategies, one in speech and the other in gesture. The children thus appeared to be shaping their own learning environments just by moving their hands. Gesture not only reflects a child's understanding but can play a role in eliciting input that could shape that understanding. As such, it may be part of the mechanism of cognitive change.     

体感游戏促进儿童的执行功能：运动强度和认知参与的作用

为了考察体感游戏促进儿童执行功能的作用机制, 采用2(运动强度：高/低) × 2(认知参与：高/低) × 3(测量时间：前测、一次性训练后测、长期训练后测)的三因素混合实验设计, 对122名4~6岁儿童进行6周(每周3次)的体感游戏训练。结果发现：在一次性训练中, 体感游戏中的运动强度而不是认知参与显著促进儿童执行功能, 尤其是工作记忆; 在长期干预中, 体感游戏中的运动强度和认知参与都显著促进儿童执行功能, 且认知参与的作用大于运动强度。这一结果不但验证了体感游戏对儿童执行功能的益处, 并且阐明了体感游戏中的哪些特征能对儿童执行功能具有短期的和长期的效果。     

Parent and Child Effects on Cognitive Performance: An Experimental Approach to the Etiological and Responsive Theories of Schizophrenia

While many theorists have assumed that the family has an etiological part in the development of schizophrenia, most findings, since they come predominantly from observations after the illness has occurred, could plausibly be interpreted as family responses to the illness. In this experimental study, we constructed artificial families in order to measure independently of each other the effects of parents of schizophrenics on children and the effects of schizophrenic children on parents. Findings from a cognitive task requiring abilities to attend and abstract show that the presence of a schizophrenic child has only minor disruptive effects upon the performance of normal parents; parents of schizophrenics also have little effect upon normal children. Instead, the most consistent effects are those of normal parents on the schizophrenic child. Adolescent schizophrenic patients whose cognitive performance deficit is apparent prior to the experiment show significant improvement after having worked on the cognitive task with normal parents; their cognitive deficit disappears, and their performance is not different from matched normal children. Further investigation will center on the quality of the normal parents' “normalizing” effects.     

Cognitive biases and obsessive-compulsive symptoms in children: examining the role of maternal cognitive bias and child age

Objective: Multiple cognitive biases associated with adult obsessive-compulsive disorder (OCD) were tested in a clinical sample of children (ages 7-11) and adolescents (12-17) and their mothers. This study examined (a) the associations between child cognitive biases and OCD severity, (b) maternal cognitive biases and child OCD severity, and (c) maternal cognitive bias and child cognitive bias. It was hypothesized that age would significantly moderate these relationships, with stronger associations with OCD severity for cognitive bias in adolescents (relative to children), and maternal cognitive bias in younger children (relative to adolescents). Method: Forty-six children and adolescents diagnosed with OCD and their mothers completed questionnaires assessing responsibility bias, thought-action fusion (TAF), thought suppression, and metacognitive beliefs. OCD symptoms were assessed using structured diagnostic interviews and semistructured symptom interviews. Results: As predicted, age significantly moderated associations between (a) child cognitive variables and OCD severity-specifically between child responsibility and child metacognition, which were associated with OCD severity for adolescents only; (b) maternal cognitive biases and child OCD severity-specifically for maternal responsibility and thought suppression, which were significantly and positively associated with child OCD severity but not adolescent OCD severity; and (c) maternal cognitive biases and child cognitive bias-such that significant associations were evident only in the younger child sample, and only between maternal TAF self and metacognition, with child suppression and child TAF moral, respectively. Conclusion: Maternal cognitive biases are more consistently linked to greater OCD severity among younger children, whereas personal cognitive biases are associated with greater OCD symptoms in adolescents. Treatments for pediatric OCD are likely to be improved by age-specific considerations for the role of maternal and child cognitive biases associated with OCD.

Interpretation and Expectation in Childhood Anxiety Disorders: Age Effects and Social Specificity

Theory and treatment for childhood anxiety disorders typically implicates children’s negative cognitions, yet little is known about the characteristics of thinking styles of clinically anxious children. In particular, it is unclear whether differences in thinking styles between children with anxiety disorders and non-anxious children vary as a function of child age, whether particular cognitive distortions are associated with childhood anxiety disorders at different child ages, and whether cognitive content is disorder-specific. The current study addressed these questions among 120 7–12 year old children (53% female) who met diagnostic criteria for social anxiety disorder, other anxiety disorder, or who were not currently anxious. Contrary to expectations, threat interpretation was not inflated amongst anxious compared to non-anxious children at any age, although older (10–12 year old) anxious children did differ from non-anxious children on measures of perceived coping. The notion of cognitive-content specificity was not supported across the age-range. The findings challenge current treatment models of childhood anxiety, and suggest that a focus on changing anxious children’s cognitions is not warranted in mid-childhood, and in late childhood cognitive approaches may be better focussed on promoting children’s perceptions of control rather than challenging threat interpretations.     

Antecedents of emotion knowledge: Predictors of individual differences in young children

Individual differences in emotion knowledge were examined among 188 4-year-old, predominantly African American children. Cognitive ability and negative emotionality, maternal characteristics (parenting, verbal intelligence, and depressive symptoms), environmental risk, and child sex were examined as predictors of emotion knowledge. Regression analyses indicated that cognitively skilled children who resided in relatively low risk environments with verbally intelligent mothers possessed greater emotion knowledge. Proximal (4-year) child cognitive ability was a stronger predictor than distal (2-year) cognitive ability. Positive parenting at 4 years was correlated with child emotion knowledge, but this relation disappeared when parenting was examined in the context of other predictors. These findings highlight the potential role of child cognitive ability, along with environmental risk and maternal verbal intelligence, in children's emotion knowledge and demonstrate the importance of examining a variety of predictors for their unique contribution to emotion knowledge.     

Can Young Children Distinguish Abstract Expressionist Art From Superficially Similar Works by Preschoolers and Animals?

While it is sometimes claimed that abstract art requires little skill and is indistinguishable from the scribbles of young children, recent research has shown that even adults with no training in art can distinguish works by abstract expressionists from superficially similar works by children and even elephants, monkeys, and apes (Hawley-Dolan & Winner, 2011). We presented 4-7- and 8-10-year-olds with 18 paired images, one in each pair by an abstract expressionist and the other by a child or animal, and asked which they preferred and which was better. Each participant viewed the first third of the pairs unlabeled and the rest either with correct or reversed labels (artist, and child, monkey, or elephant). Three unexpected findings emerged. First, even 4-7-year-olds can distinguish works by artists from superficially similar works by children and animals when there are no labels to guide them. Second, children’s aesthetic responses are not aligned with those of adults: children often chose works labeled child or animal whether or not this label was correct, and sometimes justified their choices by crediting the effort the child or animal had made (e.g., “it’s really good for an elephant”). Finally, children, like adults, were more likely to select artist images when making quality judgments than when indicating preferences, showing that they make a distinction between intuitive preference responses and more cognitive quality judgment responses. That even preschoolers can discriminate between works by abstract expressionists and works by children and animals underscores what is wrong with the oft-heard statement, “My kid could have done that.”     

Socialization and cognition in children between the age of 18 and 24 months

A cross-cultural study of mother–child dyads was set up to test the hypothesis that sociocultural differences, mediated by variations of maternal intervention, influence the way in which the child manipulates objects and, thereby, his cognitive and social competences. Two series of observations were conducted with three groups of children aged 18–24 months (15 from the American middle class, 15 from French families and 15 from North African families—the last two groups both underprivileged): (a) ‘naturalistic’ observations of two systems of interaction (child–mother and child–children interaction) showed that each child is characterized by one type of object manipulation (protected, induced, activated or autonomous) and that maternal intervention varies with the sociocultural background; assessment of the child's behavioural sequences unravelled his strategies for solving and avoiding conflicts with his peers; (b) observations of the child with a standardized material permitted an evaluation of his cognitive competences for spontaneous problem-solving. Regarding the assumptions of our hypothesis, the results furnish the following conclusions: (1) social and cognitive competences are related to the object manipulation type. In all samples, children characterized by ‘activated’ and ‘autonomous’ manipulation obtain the better results; (2) maternal intervention differs among the samples depending on the sociocultural background; these differences (limitation and physical contact) do not correspond to differences in types of manipulation; (3) type of manipulation is an interactive construction; it characterizes the functioning of the mother–child dyad and its prevailing dynamics between permanence and change. ©1997 by John Wiley & Sons, Ltd.     

Siblings' Direct and Indirect Contributions to Child Development

Abstract— Since the early 1980s, a growing body of research has described the contributions of sibling relationships to child and adolescent development. Interactions with older siblings promote young children's language and cognitive development, their understanding of other people's emotions and perspectives, and, conversely, their development of antisocial behavior. Studies address the ways in which parents' experiences with older children contribute to their rearing of younger children, which in turn contributes to the younger children's development. Finally, by virtue of having a sibling, children may receive differential treatment from their parents. Under some conditions, differential treatment is associated with emotional and behavioral problems in children.     

No own-age bias in 3-year-old children: More evidence for the role of early experience in building face-processing biases

This study aimed to investigate the presence of an own-age bias in young children who accumulated different amounts of early experience with child faces. Discrimination abilities for upright and inverted adult and child faces were tested using a delayed two-alternative, forced-choice matching-to-sample task in two groups of 3-year-old children, one composed of first-born children and the other composed of children who, from the time of their birth, had daily exposure to a child face through the presence of an older sibling in their home. Children without an older sibling were better at differentiating among adult faces than among child faces and showed an inversion effect that was selective for adult faces. Children with an older sibling were equally skilled at differentiating upright adult and child faces and showed inversion effects of comparable magnitude for both face types. Results support the notion that face representational space of younger children is tuned to adult faces and suggest that age biases during early childhood are dependent on the effects of early experience.     

Relation of birth weight, maternal intelligence and mother–child interactions to cognitive and play competence of Jamaican two-year old children

The present study assessed whether birth weight, maternal child rearing behaviors, and maternal intelligence combine in an additive or in a non-linear interactive fashion to influence cognitive performance in a sample of 24-month old full-term appropriate and low birth weight Jamaican children. Child cognitive performance was measured using the Griffiths Scale and a laboratory based assessment of the amount of time the child utilized different levels of play behavior. Mothers were videotaped while playing with their children under different instructional conditions and videotapes were coded for 8 maternal interaction patterns. Maternal verbal intelligence was assessed using the PPVT. Results supported the operation of both additive co-action as well as non-linear interactive processes. Birth weight, maternal behaviors toward her child and maternal intelligence predicted child cognitive performance. In addition, low birth weight infants were either less sensitive to facilitative aspects of maternal behaviors and/or more sensitive to maternal inhibitory behaviors than were appropriate birth weight infants. Further, child rearing behaviors of more intelligent mothers were a stronger influence on their child's cognitive performance than those of less intelligent mothers, even when there were no differences in the level of behaviors of more or less intelligent mothers.     

Memory, acquisition, and category clustering in learning-disabled children.

In Experiment 1, single trial, immediate-free recall of learning disabled and nondisabled children was compared. The primacy effect in learning-disabled children was lower, suggesting that rehearsal or other types of elaborative encoding may be deficient in these children. In Experiment 2, acquisition of randomly presented categorical lists in a multitrial-free recall task was compared in learning disabled and nondisabled children. One-half of each group was required to learn the same number of words (34 per list), whereas list length for the other half exceeded the primacy effect of each child in immediate-free recall to the same degree. When the same number of items was learned, acquisition was slower in learning disabled than nondisabled children. When the number of items varied according to the primacy effect of each child, acquisition of both groups was similar. Clustering was lower in learning disabled than nondisabled children. In Experiment 3, multitrial-free recall acquisition of categorical lists was examined in a subject-paced task. When the number of words learned exceeded the primacy effect of each child to the same degree, trials to criterion were similar in both groups but, when the children learned the same number of items, learning-disabled children required more trials to criterion. Presentation rates were faster in learning-disabled children. Presentation rates were negatively correlated with trials to criterion and positively correlated with clustering and primacy in immediate-free recall, suggesting that study time may be taken up by clustering, rehearsal, and/or other encoding strategies. Deficient elaborative encoding may be responsible for the slower acquisition of learning-disabled children.     

Interrogative types in parental speech to language-learning children: A linguistic universal?

The present study investigated the frequency of occurrence of various interrogative types in the language of American mothers (English) and Israeli mothers (Hebrew) to their 24-month-old language-learning children. It was found that both groups of mothers produced a similar hierarchy of the various wh-questions. The relation between these specific wh-questions and concept development in the child is discussed. It was also found that American mothers produced significantly more questions that required the child to respond with a yes-no answer, while Israeli mothers produced significantly more wh-questions which placed the cognitive burden of the verbal interaction on the child.This research was supported by a grant to the University of Minnesota's Research, Development, and Demonstration Center in Education of Handicapped Children (OEG-09-332189-4533-032) from the U.S. Office of Education, Bureau of Education for the Handicapped.     

Children's cognitive maps of large-scale spaces: Effects of exploration,direction, and repeated experience

Kindergarteners and third graders (mean ages 5–10 and 8–9 years) repeatedly encountered a model town and then constructed the town from memory. In Experiment 1, the effect of different types of exploration on the development of a cognitive map was assessed. Children who were directed to walk within the town placed buildings more accurately than children who had walked along the town's perimeter. Children who walked within the town and were directed to the spatial relationships among buildings had the highest placement accuracy. Third graders were more accurate than kindergarteners across the three types of exploration. In Experiment 2, children were permitted to explore the town alone for an unlimited amount of time. Under these conditions, third graders still placed buildings more accurately than kindergarteners. A comparison of Experiments 1 and 2 indicated that children developed more accurate cognitive maps when motor activity and attention were directed by the experimenter as opposed to being directed by the child. Accuracy improved with repeated walks and constructions in both experiments, and the results of Experiment 3 suggested that constructing facilitated the development of the cognitive map as much as walking. It was concluded that third graders' cognitive maps were more accurate than kindergarteners' maps due to differences in the speed of acquisition and storage of spatial information.     

Attachment at school age and academic performance.

The association between attachment and school-related cognitive functioning was longitudinally examined for a French Canadian sample of 108 school-age children. The affective quality of mother-child interaction patterns, child cognitive engagement, and quality of child attachment to mother were evaluated during a laboratory visit that included a separation-reunion procedure occurring when the children were approximately 6 years of age. Children's mastery motivation and academic performance were assessed 2 years later (at age 8). Analyses indicated that secure children had higher scores than their insecure peers on communication, cognitive engagement, and mastery motivation. Controlling children were at greatest risk for school underachievement, with the poorest performance on all measures except mastery motivation. Avoidant and ambivalent children were lowest on mastery motivation. Results of mediational analyses support the salience of mother-child interactional processes and child cognitive engagement at school age in explaining relations between attachment and cognitive functioning in school.     

Investigating Individual Differences in Toddler Search with Mixture Models

Children's performance on cognitive tasks is often described in categorical terms in that a child is described as either passing or failing a test, or knowing or not knowing some concept. We used binomial mixture models to determine whether individual children could be classified as passing or failing two search tasks, the DeLoache model room task and the Berthier et al. door task. The data support categorical classification of the children and suggest that the increase in average proportion correct with age is the result of an increasing proportion of children who can solve the tasks. Performance on the two tasks was concordant, and improving performance could be due to advances in a single psychological ability, such as cognitive control.

Parent–child interaction,task-oriented regulation,and cognitive development in toddlers facing developmental risks

The importance of supportive parent–child interactions and the development of regulatory abilities with regard to growth in children's cognitive abilities has been established. This study investigated the longitudinal relations among parental supportiveness, child task-oriented regulation, and cognitive development for low-income children facing developmental risks. Interlocking growth models were fit to these variables based on measurements made when the children were 14, 24, and 36 months of age. Results showed that growth rates of child cognition were related to baseline (14 months) parental supportiveness and changes in child task-oriented regulation. We additionally found that baseline levels of cognition were related to the baseline levels of child task-oriented regulation. This study suggests that both parental supportiveness during infancy and the concurrent development of child task-oriented regulation are related to cognitive development among children facing developmental risks.     

Light and color in a void: The analysis of a special needs child

This clinical report comes from the five year, four day a week analysis of a male child. What is special is that this treatment is of a child with marked mental retardation. I have retained this nomenclature because that is how Ricardo's parents described his mental capacity. What they meant was that he was greatly impaired in his cognition and this could be seen in Ricardo's severe cognitive, social, behavioral, and relational improprieties. I have privileged the function of psychoanalytic understanding and the role of transference to bring about modifications in this child's internal world. And I have considered the patient's psychotic mental state to be in need of psychoanalytic treatment not withstanding his psychosis's connection to his cognitive handicap. I have also added information I have received after the analysis, information that demonstrates continued integration coming from the analytic process. Owing to Ricardo's limited mental capacities, this article advances clinical information that is not often found in analyses of children. There are possibly many other children like him who nonetheless would benefit from dynamic psychoanalytic understanding. On the other hand, I shall not discuss this matter theoretically, even though some theoretic considerations are necessary. Clinical practice and the transferential relation are this report's principal material.     

Effects of "Dirty" Information on Disgust Responding to an Unknown Animal in Children: The Moderating Role of Maternal Disgust Proneness

Although research has shown that disgust facilitates avoidance of small animals among adults, much less is known about disgust appraisals of small animals in children as well as the predictors of such appraisals. To address this gap, children (ages 5–13) were exposed to dirt-related and cleanliness-related information about unknown animals. The extent to which these types of information influenced children's feelings of fear, disgust, positivity, and avoidance behavior in relation to the animals was examined. The present study then examined the extent to which child and maternal disgust proneness predicted feelings of disgust to the ‘dirty’ animal. The findings show that providing dirt-related information resulted in a significant increase in disgust, but not fear, responding to the animal. Dirt-related information also resulted in a significant decrease in positive feelings toward the animal. Conversely, providing cleanliness-related information resulted in a significant decrease in disgust, but not fear, responding to the animal. In addition, providing cleanliness-related information resulted in a significant increase in positive feelings toward the animal. Children also engage in more avoidance of the animal described as dirty compared to the animal described as clean. In addition, subsequent analysis revealed an interaction between child and maternal disgust propensity in predicting learned disgust to the dirty animal such that the highest levels of feelings of disgust to the dirty animal were observed among children with high disgust proneness who also have mothers with high disgust proneness. The implications of these findings for conceptualizing the role of disgust in animal phobias among youth will be discussed.
