In a sample of 39 children with mathematical learning disabilities (MLD) and 106 typically developing controls belonging to three control groups of three different ages, we found that visual perception, motor skills and visual-motor integration explained a substantial proportion of the variance in either number fact retrieval or procedural calculation. Furthermore, children with MLD performed significantly worse on visual perception, motor skills and visual-motor integration in comparison with age-matched control children. A mild developmental delay in visual perception, visual-motor integration and (fine) motor coordination and a severe delay in motor skills were found in children with MLD. However, not all children with MLD have problems on these domains. They seem to be a heterogeneous group, not only with respect to their mathematical profile but also with respect to their visual perceptual, motor and visual-motor integration skills. Diagnostic implications are discussed. 相似文献

This study examined whether children's cognitive appraisal biases moderate the impact of stressful divorce-related events on psychological adjustment in 355 children ages 9 to 12, whose families had experienced divorce within the past 2 years. Multiple regression indicated that endorsement of negative cognitive errors for hypothetical divorce events moderates the relations between stressful divorce events and self- and maternal reports of internalizing and externalizing symptoms, but only for older children. Positive illusions buffer the effects of stressful divorce events on child-reported depression and mother-reported externalizing problems. Implications of these results for theories of stress and coping, as well as for interventions for children of divorced families, are discussed. 相似文献

Events involving motion in fall are differentiated psychologically from events involving horizontal motion. Do children associate motion down inclines more with motion along horizontals or more with motion in fall, or do they even treat it as an integration of the two? The question was raised over 20 years ago but never satisfactorily answered, so the principal aim of the reported research was to take matters forward. Children (n?=?144) aged 5–11 years were assessed while predicting natural dynamic events along a horizontal, in fall and down an incline. They were required to make predictions of speed with heavy and light balls and under changes in incline heights. The results show that, consistent with previous work, faster horizontal motion was associated with the light ball across all ages, whereas faster fall was associated with the heavy ball. However, while the younger children predicted faster incline motion for the lighter ball, there was a shift in this conception towards older children predicting faster motion for the heavier ball. Understanding of how changes in incline height affect speed was generally good, with this aspect of the study helping to establish how children perceive diagonal dimensions. How supported horizontal motion and unsupported fall motion may affect children's changing understanding of incline motion is discussed, thus providing more complete insight into children's understanding of natural object motion than has been established so far. 相似文献

Improbable or impossible? How children reason about the possibility of extraordinary events 总被引：1，自引：1，他引：0
The present study investigated the development of possibility-judgment strategies between the ages of 4 and 8. In Experiment 1, 48 children and 16 adults were asked whether a variety of extraordinary events could or could not occur in real life. Although children of all ages denied the possibility of events that adults also judged impossible, children frequently denied the possibility of events that adults judged improbable but not impossible. Three additional experiments varied the manner in which possibility judgments were elicited and confirmed the robustness of preschoolers' tendency to judge improbable events impossible. Overall, it is argued that children initially mistake their inability to imagine circumstances that would allow an event to occur for evidence that no such circumstances exist. 相似文献

Beliefs about naturally occurring transformations were examined in children aged 3 to 6 years in 4 experiments. Experiment 1 tested children's understanding that animals (but not artifacts) predictably get larger over time. Experiment 1a examined whether the results obtained in the first experiment could be attributed to an added memory component on the artifact task. Experiment 2 further examined beliefs about the aging of artifacts. In Experiment 3, color and shape (metamorphosis) changes of animals were investigated. At all ages, children appeared to understand that animals get larger and not smaller with age. While older children and adults allowed for rather dramatic changes in the size and shape of animals over the life span if the alternative involved decreasing in size with age, preschool children were less willing to accept these changes. Taken together, the results of these studies suggest that even young preschool children have 2 conceptual insights about natural transformations: that they are lawful and nonrandom, and that they are domain and mechanism specific. Further, children as young as age 3 are able to go beyond the perceptual appearance of animals in making judgments about transformations caused by growth. Implications for children's understanding of personal and species identity are discussed. 相似文献

A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a particular spatial location rather than to an object. Results show that 10-month-olds can learn new labels and do so by relying on the perceptual salience of an object instead of social cues provided by a speaker. This is in direct contrast to the way in which older children (12-, 18-, and 24-month-olds) learn and extend new object names. 相似文献

Conclusion The young child is in motion most of the time. Through movement, the child achieves mastery of the space he or she lives in.
Teachers can “move” with the child by using topologically oriented science activities. Such activities capitalize on natural
inclinations. They encourge the understanding of relationships which are basic to the developmental tasks with which the child
is working.

72 children, ages 6 to 11 years, were presented with a series of stories involving psychological harm (name-calling) in a game context. Situations were presented in which intentions, consequences, and game context were varied, along with order of story presentation. Comparisons between acts of physical and psychological harm were also conducted. Although responses in some conditions were influenced by order of presentation, age differences were found in children's evaluations of agents' actions and recipients' reactions for psychological harm in game contexts. Younger children were more likely to ignore intentions and consequences or the recipient's perspective and to focus on contextual features (e.g., game rules). Older children were more likely to base their evaluations on intentions, or both intentions and consequences, and to take into account the recipient's perspective. Game context interacted differentially with psychological and physical harm at all ages. Evaluations of acts of physical harm were more likely than acts of psychological harm to be transformed by game context. 相似文献

The study tested whether children's prosocial behavior was negatively or positively related to children's and mothers' psychological problems. Participants were 149 London families when mothers were pregnant and followed up in infancy and at ages 4 and 11. Children's cooperation at 4 and general prosocial tendencies at 11 were negatively associated with externalizing problems but unrelated to internalizing problems. A subgroup of children who were more prosocial than average expressed clinically significant worries about family members. Maternal depression decreased prosocial behavior in the eyes of adults, but children of depressed mothers saw themselves to be prosocial. Early cooperation protected children against later risk for externalizing problems, even when their early behavioral problems were taken into account. 相似文献

Children's Causal Explanations of Animate and Inanimate Motion 总被引：3，自引：0，他引：3
Adults frequently refer to nonobvious, internal, or immanent causal mechanisms when explaining certain kinds of movement— such as the movement of animals (e.g., a rabbit hops because of its brain and muscles) and the self-sustained movement of artifacts (e.g., a toy moves on its own because of batteries or gears). This series of studies examined whether and when preschool children are willing to attribute internal and immanent causes to motion. In 3 studies, preschool children and adults viewed animals and artifacts (wind-up toys and transparent objects) either moving independently or being transported by a person. Children explained animal and artifact events differently, even with the kind of movement controlled: They were more likely to attribute immanent cause to animals than to artifacts and more likely to attribute human cause to artifacts than animals. Internal causes were less frequently endorsed overall; however, when asked to describe the insides of artifacts, children who saw them moving alone more often described internal mechanisms (e.g., batteries, electricity) than children who did not see them moving alone. Altogether, the studies suggest that children as young as 3 or 4 years of age honor two principles: For animals more than for artifacts, movement is caused by an immanent source, and across domains, movements without an observable agent have an internal or immanent source. 相似文献

Recent research into children’s conceptual representation-much of it based on the so-called ‘triads’ task-has created a number of issues such as the age at which children become capable of representation at the superordinate level; the relative prominence of taxonomic, perceptual or thematic relations as the basis of representation; and the range of categories to which these different representations apply at different ages. In the study reported in this paper we presented children of three different ages with three types of triads designed to assess children’s sensitivity to these different relations separately across ten common superordinate categories. The approach which allowed us to track preferences for perceptual, thematic and taxonomic relations simultaneously across the three age groups showed an increase in sensitivity to both thematic and taxonomic relations with age. We conclude by suggesting that these relations are part of a common representation based on patterns of covariation within (static taxonomic relations) and across (event relations) time. 相似文献

This is a series of studies that attempted to obtain some systematic data on the capacity of children between the ages of 5 and 12 to consent to psychological research. Most of the children understood all or most of what they were asked to do in a psychology study, but few children below the age of 12 fully understood or believed that their performance would be confidential. Similarly, most children appeared to know that they could end their participation in the study, but younger children were not clear on the details of how to accomplish this, and many of all ages believed that there would be some negative consequences if they asked to stop. Moreover, obtaining prior permission from parents, while providing protection for the children, appeared to introduce additional pressure on them to agree to participate in the research and to continue once they had agreed. It is concluded that in general children of these ages do have the capacity to meaningfully assent to participation in research, but that there are substantial problems in guaranteeing that they are able to make this decision freely. 相似文献

This study examined children's conceptions of flags as social conventions and understandings of the symbolic and psychological consequences associated with transgressions toward flags. Seventy-two children, at 6, 8, and 10 years, answered general questions about flags as social conventions and judged flag-burning scenarios in which intentions of agents and consequences for recipients were varied. Flag-burning acts were motivated by symbolic, accidental, or instrumental intentions and occurred in public or private. Children at all ages viewed flags as social conventions (i.e., alterable), and symbolic acts of flag-burning occurring in public locations were judged more negatively than private transgressions. Age differences were found in evaluations of instrumental violations and in justifications used to evaluate flag-burning incidents. Overall, findings suggest that despite age-related increases in understanding of flags as meaningful collective symbols, children at all ages considered transgressions to be important and to have moral consequences (i.e., psychological harm). 相似文献

Theory of mind development in deaf children: a nonverbal test of false-belief understanding 总被引：4，自引：0，他引：4
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

Increasing Steps in Recall of Events: Factors Facilitating Immediate and Long-Term Memory in 13.5- and 16.5-Month-Old Children 总被引：2，自引：0，他引：2
Children late in the second year of life show patterns of event recall similar to those of older children: (a) well-ordered immediate and delayed recall, and (b) facilitation of recall by familiarity and by enabling relations. We used elicited imitation to test whether the patterns extend to children early in the second year. In Experiment 1, 13.5- and 16.5-month-olds accurately recalled familiar and novel 2-act sequences immediately and after a 1-week delay. For 16.5-month-olds, recall was facilitated by familiarity and by enabling relations; for 13.5-month-olds, only enabling relations facilitated recall. In Experiment 2, verbal cues were used to test immediate and 1-week delayed recall of 3-act sequences. For both ages, recall was facilitated by familiarity and by enabling relations. Experiment 3 verified that the verbal information served to cue recall of previously experienced events, not to "suggest" sequences that could be performed. Together the results demonstrate that children as young as 13 months can recall specific events after a delay. They also suggest development in sensitivity to factors that facilitate recall. 相似文献

One hundred twenty-eight children in preschool through fifth grade (range = 4,3-11,4) and 76 adults serving as a comparison group participated in two studies that examined how children reason about psychogenic bodily reactions, that is, ailments or nonconscious physiological responses with origins in the mind (e.g., stress-induced headache). Psychogenic bodily reactions provide an opportunity to study how children integrate knowledge between the domains of bodily response and psychology. In Study 1, participants were asked whether various familiar psychogenic bodily reactions were possible (e.g., can someone get a tummyache from worrying?). In Study 2, participants were presented with a novel domain (hypothetical "aliens" from outer space) and were asked whether various unfamiliar bodily conditions (e.g., toes swelling) could arise from various physical or psychological causes. As predicted, adults typically reported that psychogenic bodily reactions were possible, and that unfamiliar bodily conditions could result from either psychological or physical causes. In contrast, young children typically denied that psychogenic bodily reactions could occur and predicted that unfamiliar bodily conditions resulted from physical causes only. The results support a developmental path: younger children view psychogenic bodily responses as wholly physical, but with age, view them as both physical and psychological phenomena. 相似文献

The double-deficit theory of reading disability (Wolf & Bowers, 1999) was examined in a sample of 56 reading-disabled and 45 normal-reading elementary school children (aged 8 to 11). As hypothesized, the two groups differed markedly on all phonological analysis tasks and on rapid continuous naming of digits and letters (the double deficits), but they differed as well on orthographic tasks, attention ratings, arithmetic achievement, and all WISC-III factors except perceptual organization. Within the reading-disabled (RD) sample, children in the double-deficit subgroup were no more impaired in reading and spelling than those with a single deficit in phonological analysis, and those with a single deficit in rapid naming were no more impaired than those with neither deficit. Multiple regression analyses suggest that a multiple causality theory of RD is more plausible than a double-deficit theory. 相似文献

Infants' (N = 276) ability to learn from television under seminaturalistic conditions was examined in five experiments with 12-, 15-, and 18-month-olds. In all experiments, an adult performed a series of specific actions with novel stimuli. Some infants watched the demonstration live, and some infants watched the same demonstration on television from prerecorded videotape. Infants' ability to reproduce the target actions was then assessed either immediately or after a 24-hour delay. Infants of all ages exhibited imitation when the actions were modeled live. There were age-related and task-related differences, however, in infants' ability to imitate the same actions modeled on television. The role of perceptual, attentional, and cognitive development in the ability to learn from television is discussed. 相似文献

Four experiments utilizing the habituation procedure examined 10- to 18-month-olds' ability to detect and encode correlations among features in a motion event (N = 136). Infants were habituated to two events in which objects-with distinct parts and a distinct body-moved across a screen along a rectilinear or curvilinear motion path. Infants were then tested with one familiar event and three events in which one feature of the object (parts, body, or motion path) was presented in a novel combination with the other features. The results of the experiments revealed that 10-month-olds process independently static features in an event, but do not process correlations among dynamic features; whereas 14-month-olds detect the correlation between an object's parts and its motion trajectory, but only when the movement of parts is correlated with the motion of the object. Further, the data show that 18-month-olds detect correlations between all three features when the parts of the object move, but they detect only the relation between parts and motion path when the parts do not move. It is proposed that infants develop representations for the static and dynamic properties of objects through a sensitive perceptual system that detects individual features, whole objects, and movement properties, and a domain-general associative learning mechanism that encodes independent features and correlations among features. 相似文献
