Self-representations and socioemotional competence in young children: a 3-year longitudinal study

In a longitudinal study, the connections between children's self-representations at age 5 and their self-perceptions, socioemotional competence according to the teacher, and peer acceptance at age 8 were examined. The sample consisted of 60 children (33 boys, 27 girls). Self-representations at age 5 were assessed by the Puppet Interview (J. Cassidy, 1988). Results generally revealed the expected connections between the positiveness of self at age 5 and self-perceptions and socioemotional functioning 3 years later. These findings support the predictive validity of the Puppet Interview. Moreover, they suggest that young children do possess at least a rudimentary sense of being generally worthy and lovable, which can be assessed by using adequate, age-appropriate interviews.     

Transfer of a memorization strategy in 10-year-old children: study of individual differences]

The spontaneous or induced use of an organization strategy is examined on free recall tasks with 10-year-old children classified as rather global or rather analytical at the Group Embedded Figures test. The experimental procedure include three successive and identical tests followed by two deffered tasks, one requiring a transfer of maintenance and the other a transfer of generalization. The experimental group, who attended a simple illustration of the organization strategy before the second test, applied the strategy quickly and successfully: for these subjects, one does not note differences between global or analytical subjects in the recall performance; however, the global subjects modify their study strategy of the material on the generalization task. For the control group, global or analytical subjects have a different evolution for the performance and the strategic attitude according to the procedure. The analytical subjects are different from global subjects on the generalization task.     

Development of cognitive strategies and self control strategies in 8 to 14-year-old children]

This study examines the interaction between the development of cognitive strategies and self-monitoring abilities in children aged 8 to 14. Children were tested individually on eight proportionality problems presented with the balance-scale task. Cognitive development was assessed by the strategy used and the performance on each problem. The indicators of self-monitoring were: latencies before and after the solution of a problem, self-evaluation of one's ability to make the balance scale stay level, proportion of oriented moves on the balance scale, and persistence on a problem. Children's self-monitoring reactions to failure were assessed by changes in strategies, verbal explanations, self-evaluation of performance, and latencies. Results showed an interaction between the complexity of the items and cognitive level. On more complex items, children of lower cognitive levels had shorter latencies, made more (but less oriented) moves on the balance scale, persisted less in their activity, and had more difficulty to evaluate properly their performance. Following failure, children of lower cognitive levels did a less accurate evaluation of their performance, modified their strategy, and did not change their verbal justification, whereas children of higher cognitive levels did a good evaluation of their performance, did not change their strategy, and had the tendency to change their verbal justification. Following failure, all children took less time planning their activity. The results suggest that self-monitoring abilities develop according to the development of cognitive strategies and are mediated by the complexity of the task.     

Similarity predicts liking in 3-year-old children

Two studies examined the influence of similarity on 3-year-old children’s initial liking of their peers. Children were presented with pairs of childlike puppets who were either similar or dissimilar to them on a specified dimension and then were asked to choose one of the puppets to play with as a measure of liking. Children selected the puppet whose food preferences or physical appearance matched their own. Unpacking the physical appearance finding revealed that the stable similarity of hair color may influence liking more strongly than the transient similarity of shirt color. A second study showed that children also prefer to play with a peer who shares their toy preferences, yet importantly, show no bias toward a peer who is similar on an arbitrary dimension. The findings provide insight into the earliest development of peer relations in young children.     

Predictors of perceived satisfaction with parental control in Chinese adolescents: a 3-year longitudinal study

Over three consecutive years, 2,559 Chinese adolescents (mean age = 12.65 years at Wave 1) responded to instruments assessing their trust of parents, perceived parental trust of the children, readiness to communicate with the parents, and satisfaction with parental control. Results showed that mutual trust between the parents and their adolescent children and the children's readiness to communicate with the parents were related to perceived satisfaction with parental control at Time 1, Time 2, and Time 3. Although readiness to communicate with the parents and mutual trust between the parents and their adolescent children predicted perceived satisfaction with parental behavioral control and its change over time, trust of the parent was the strongest predictor. While the influence of trust of the father on satisfaction with paternal control was stronger for adolescent girls than for adolescent boys, influence of paternal trust on satisfaction with paternal control was stronger for adolescent boys than for adolescent girls.     

Predictors of reading development in deaf children: A 3-year longitudinal study

The development of reading ability in a group of deaf children was followed over a 3-year period. A total of 29 deaf children (7-8 years of age at the first assessment) participated in the study, and every 12 months they were given a battery of literacy, cognitive, and language tasks. Earlier vocabulary and speechreading skills predicted longitudinal growth in reading achievement. The relations between reading and the predictor variables showed developmental change. Earlier reading ability was related to later phonological awareness skills, suggesting that deaf children might develop their phonological awareness through reading. Deaf children who had the most age-appropriate reading skills tended to have less severe hearing losses and earlier diagnoses and also preferred to communicate through speech. The theoretical implications of the role for speechreading, vocabulary and phonological awareness in deaf children’s literacy are discussed.     

A longitudinal analysis of the attention networks in 6- to 11-year-old children

Attention is critical for everyday functioning. Posner and Petersen’s model of attention describes three neural networks involved in attention control—the alerting network for arousal, the orienting network for selecting sensory input and reorienting attention, and the executive network for the regulatory control of attention. No longitudinal research has examined relative change in these networks in children. A modified version of the attention network task (ANT) was used to examine changes in the three attention networks, three times over 12 months, in 114 6-, 8- and 10-year-olds. Findings showed that the alerting network continued to develop over this period, the orienting network had stabilized by 6 years, and the conflict network had largely stabilized by 7 years. The reorienting of attention was also assessed using invalid cues, which showed a similar developmental trajectory to the orienting attention network and had stabilized by 6 years. The results confirm that age 6 to 7 years is a critical period in the development of attention, in particular executive attention. The largest improvement over the evaluation period was between 6 and 7 years; however, subtle changes were found in attention beyond 8 years of age.     

Categorization and abstraction abilities in 3-year-old children: a comparison with monkey data

Three-year-old children were tested on three categorization tasks of increasing levels of abstraction (used with adult baboons in an earlier study): the first was a conceptual categorization task (food vs toys), the second a perceptual matching task (same vs different objects), and the third a relational matching task in which the children had to sort pairs according to whether or not the two items belonged to the same or different categories. The children were tested using two different procedures, the first a replication of the procedure used with the baboons (pulling one rope for a category or a relationship between two objects, and another rope for the other category or relationship), the second a task based upon childrens prior experiences with sorting objects (putting in the same box objects belonging to the same category or a pair of objects exemplifying the same relation). The children were able to solve the first task (conceptual categorization) when tested with the sorting into boxes procedure, and the second task (perceptual matching) when tested with both procedures. The children were able to master the third task (relational matching) only when the rules were clearly explained to them, but not when they could only watch sorting examples. In fact, the relational matching task without explanation requires analogy abilities that do not seem to be fully developed at 3 years of age. The discrepancies in performances between children tested with the two procedures, with the task explained or not, and the discrepancies observed between children and baboons are discussed in relation to differences between species and/or problem-solving strategies.     

Temporal generalization in 3- to 8-year-old children

Children aged 3, 5, and 8 years were tested on temporal generalization with visual stimuli. Different groups received 4- and 8-s standards. Gradients at all ages superimposed when plotted on the same relative scale, indicating underlying scalar timing. The principal developmental changes were (i) increasing sharpness of the generalization gradient with increasing age and (ii) a change from symmetrical (3 and 5 years) to adultlike asymmetrical generalization gradients in the oldest children. Theoretical modeling attributed these changes to increasing precision of the reference memory of the standard with increasing age, as well as a decreased tendency to "misremember" the standard as being shorter than it actually was, as the children developed.     

Categorization and normalization of vowels by 3-year-old children

A two-alternative, forced-choice procedure was used in two experiments to test 3-year-old children’s categorization of natural vowel tokens produced by several talkers. An appropriate pointing response (right or left) was visually reinforced with one of two television displays. In Experiment 1, the stimuli were isolated tokens of /a/ and /i/ produced by a male adult, a female adult, a male child, and a female child. In Experiment 2, the stimuli were isolated tokens of /æ/ and /∧/ produced by the same talkers. In both experiments, 3-year-olds spontaneously generalized their pointing responses from the male adult vowel tokens to the corresponding vowels produced by the other talkers. Children reinforced for an arbitrary grouping of the two vowel categories persisted in categorizing on the basis of vowel quality. Results from both experiments demonstrate the presence of perceptual constancy for vowel tokens across talkers. In particular, the results from Experiment 2 provide evidence for normalization of isolated, quasi-steady-state vowel tokens because the formant values for tokens of /∧/ produced by the woman and the two children were closer to the formant frequencies of the male adult’s /æ/ than to the male adult’s /∧/.     

Body-size estimations in children six through fourteen: a longitudinal study.

Estimates of perceived and ideal body size were collected in 216 boys and girls ages 6 through 14 years. Video methodology was used to adjust the width of a life-size frontal image of the children. Longitudinal data were collected annually for three years, beginning at ages 6, 9, and 12. Three psychological methods were used, including the method of adjustment, staircase method, and adaptive probit estimation technique which permitted separate measures of the children's point of subjective equality and just noticeable difference values. The point of subjective equality is the body size which is subjectively equal to the child's perception of self. The just noticeable difference is the amount of change in body size necessary to detect the difference 50% of the time. Acceptable size boundaries were also measured, using the method of adjustment. Over-all, children were accurate in estimating their body width, with average overestimation of less than 2%. Overestimation decreased within each age group during the three years of the study. There were no differences between ages or sexes. Both point of subjective equality and just noticeable difference values decreased significantly during the three years of the study. The latter values significantly decreased as children became older. Body dissatisfaction (the discrepancy between perceived and ideal size) remained low for boys in all age groups. Girls' body dissatisfaction significantly increased across ages, beginning at age 9. Test-retest consistency of both perceived and ideal size judgments at intervals of one and two years were low. Acceptable boundaries in body width were similar between sexes and across age cohorts.     

Evidence of deontic reasoning in 3- and 4-year-old children

Deontic reasoning is reasoning about what one may, ought, or ought not do in a given set of circumstances. Virtually all of our social institutions and child-rearing practices presume the capacity to reason about deontic concepts, such as what is permitted, obligated, or prohibited. Despite this, very little is known about the development of deontic reasoning. Two experiments were conducted that contrasted children’s reasoning performance on deontic and indicative reasoning tasks (i.e., the reduced array selection version of the Wason card selection task). Like adults, children as young as 3 years of age were found to adopt a violation-detecting strategy more often when reasoning about the deontic case than when reasoning about the indicative case. These results indicate that violation detection emerges as an effective deontic reasoning very early in human development.     

Episodic memory and episodic foresight in 3- and 5-year-old children

In the present study, we examined the development of episodic memory and episodic foresight. Three- and 5-year-olds were interviewed individually using a personalised timeline that included photographs of them at different points in their life. After constructing the timeline with the experimenter, each child was asked to discuss a number of different events: an event that happened yesterday, an event that happened earlier today, an event that would happen later today, and an event that would happen tomorrow. As judged by their parents, children's accounts were highly accurate. After controlling for age and language scores, there was a strong relation between amount of information reported about past and future events. Overall, 5-year-olds reported more total information than 3-year-olds; however, reports by 3-year-olds included a similar proportion of first-person reference as did reports by 5-year-olds. No age difference appeared in proportion of future-oriented talk. We conclude that the present task provides a promising method of exploring the emergence of mental time travel during early childhood.     

Fear reactivity and effortful control in overt and relational bullying: a six-month longitudinal study

This study examined the roles of fear reactivity and emotional regulatory abilities in overt and relational bullying behaviors. Survey data were collected from 124 middle school students (mean age=10.3 years, 47% males, 61% Caucasian) and their teachers in the fall and spring of a school year. Surveys included teacher- and self-rated measures of students' overt and relational bullying along with self-reported fear reactivity and effortful control. Findings show that low levels of fear reactivity and effortful control predict higher future levels of overt bullying, but not relational bullying. These results suggest that despite high correlations between overt and relational bullying, these two forms of aggression develop through different processes. The findings from this investigation are discussed with respect to their implications for theory on the development of aggression as well as prevention and intervention programming for youth aggression.     

Development of strategic skills in impulsive and reflective children: a longitudinal study of metacognition

This study examined the relationships between metamemory and strategic behavior in impulsive and reflective children. One hundred thirty children from the fourth, fifth, and sixth grades participated. Seventy-seven of these children had been tested 3 years earlier on metamemory and cognitive tempo tasks. At pretraining, children were assessed on metamemory, cognitive tempo, summarization skills, and teacher ratings of impulsive behavior in the classroom. Next, children in three experimental groups received prose summarization instructions, summarization instructions in conjunction with metacognitive training about the importance of a reflective approach to learning, or no instructions. Following training, children were again measured on tempo, summarization skills, and teacher ratings of impulsivity. Analyses of strategy maintenance data indicated superior performance for children who had received both summarization and metacognitive training. Causal modeling analyses showed that early metamemory was an antecedent of later strategy acquisition. The dual role of metacognition as a precursor of later strategy acquisition and controller of lower level strategies was highlighted.     

Autistic traits and neuropsychological performance in 6- to-10-year-old children: a population-based study

Clinical studies of children with autism spectrum disorder (ASD) provide evidence for poorer neuropsychological performance within specific domains compared to age, gender, and sometimes IQ-matched controls. Since recent evidence suggests that autistic symptoms form a spectrum that extends into the general population, it was our goal to evaluate the nature of the relationship between autistic traits and neuropsychological performance across the continuum in the general population. We examined neuropsychological performance across five different domains in 1019 6-to-10-year-old children participating in a population-based study of child development. Autistic traits were assessed when the children were 6 years of age using the Social Responsiveness Scale and ASD diagnoses were obtained via medical records. Neuropsychological functioning was measured using the NEPSY-II-NL and included the domains of attention and executive function, memory and learning, sensorimotor functioning, language, and visuospatial functioning. We found that children with higher autistic traits showed significantly lower neuropsychological performance in all domains investigated and that this association remained even after excluding children with the highest autistic traits or confirmed ASD. When comparing 41 children with confirmed ASD diagnosis to typically developing controls, children with ASD showed significantly lower neuropsychological performance across all domains. Taken together, our results suggest that children with both ASD and subclinical autistic traits have lower neuropsychological performance. Thus, this may provide an understanding of why some children without an ASD diagnosis may require some additional assistance within academic settings.     

Reorientation in a small-scale environment by 3-, 4-, and 5-year-old children

Geometric features of surfaces and local information are constitutive elements of spatial representations. A number of studies in animals (rats) and human children (24 months old) have shown that in a rectangular environment with a reward hidden in one of the corners, geometric properties predominate over local cues for search strategies. In contrast, monkeys and human adults are able to take into account both types of information (geometric and local) to reorient. So far, all of the experiments have been conducted in the locomotor space involving a navigational task. In the present study, we examined whether similar search patterns are found using a tabletop model of a rectangular room. Three groups of children (3-, 4-, and 5-year-olds) and one group of adults were tested. Results show that geometric encoding appears only at 4 years of age, that is later than in the locomotor space. The joint use of geometry and local cues emerges at 5 years of age. These data show that similar types of processing are implemented in both manipulatory and locomotor space but not at the same time. The difference between locomotor and manipulatory tasks suggests that being immersed in the environment makes this separated processing easier than being confronted by a task for which the object is exterior to the participant.
