The aim of this study was to explore the differences in procedural learning abilities between children with DCD and typically developing children by investigating the steps that lead to skill automatization (i.e., the stages of fast learning, consolidation, and slow learning). Transfer of the skill to a new situation was also assessed. We tested 34 children aged 6–12 years with and without DCD on a perceptuomotor adaptation task, a form of procedural learning that is thought to involve the cerebellum and the basal ganglia (regions whose impairment has been associated with DCD) but also other brain areas including frontal regions. The results showed similar rates of learning, consolidation, and transfer in DCD and control children. However, the DCD children's performance remained slower than that of controls throughout the procedural task and they reached a lower asymptotic performance level; the difficulties observed at the outset did not diminish with practice. 相似文献

AbstractThis article describes a contemporary systems approach to resilience in human development and its promise for integrating findings and applications across system levels. Resilience is defined as the capacity of a system for successful adaptation to disturbances that threaten system function, viability, or development. Advantages of this definition are delineated in regard to integrating sciences and disciplines across scales and levels of interaction in a bioecological systems framework. Central concepts of resilience, including pathways and cascades, are described in light of this approach, and advances that link system levels are highlighted. Given significant progress toward a more dynamic, integrated, multisystem approach, developmental resilience science stands at new frontier of possibilities that promises to inform science, practice, and policy focused on building human capacity for surviving and thriving in times of turbulence and change. 相似文献

This study investigates differences in the amount and structure of infant sleep in two cultural places with previously documented, divergent parental beliefs and practices. Eight-month-old infants (n = 24 per site) were recruited from towns in the Netherlands and the eastern U.S.A. To evaluate sleep, infants’ physical activity was recorded at home for 24 h using a miniature actigraph, while parents kept a diary of infant activities. Measures derived from actigraphy include total sleep, longest sleep episode, longest wake episode, number of sleep episodes, and percent of sleep during nighttime, as well as time in the stages of Quiet and Active Sleep. Measures based on the parental diaries include most of these aspects as well, except those related to sleep stages. Results based on the more precise actigraphy method indicate that (1) the Dutch infants averaged 13.65 h of sleep per 24 h, 1.67 h more than the U.S. infants; this difference was mostly due to daytime sleep; (2) The Dutch infants’ longest wake episode averaged less than that of the U.S. infants, while their longest sleep episode appeared slightly longer. (3) The Dutch infants, compared to the U.S. sample, spent more time in the Quiet, rather than the Active phase of sleep; (4) They began their Quiet sleep earlier in the evening than did their U.S. counterparts. Measures derived from parental diaries are largely in agreement with the actigraph findings. These results are consistent with reported and observed practices and beliefs in the two communities. The pattern of differences – less apparent maturity among the Dutch in the amount of sleep, but greater apparent maturity in the structure of sleep -- illustrates that behavioral and neurological maturity can be assessed only in the context of the developing child’s adaptation to the specific demands and affordances of the culturally structured developmental niche. 相似文献

Young children, like adults, understand that human agents can flexibly choose different actions in different contexts, and they evaluate these agents based on such choices. However, little is known about children's tendencies to attribute the capacity to choose to robots, despite increased contact with robotic agents. In this paper, we compare 5- to 7-year-old children's and adults’ attributions of free choice to a robot and to a human child by using a series of tasks measuring agency attribution, action prediction, and choice attribution. In morally neutral scenarios, children ascribed similar levels of free choice to the robot and the human, while adults were more likely to ascribe free choice to the human. For morally relevant scenarios, however, both age groups considered the robot's actions to be more constrained than the human's actions. These findings demonstrate that children and adults hold a nuanced understanding of free choice that is sensitive to both the agent type and constraints within a given scenario. 相似文献

PurposeThis study aimed to identify cases of developmental stuttering and associated comorbidities in de-identified electronic health records (EHRs) at Vanderbilt University Medical Center, and, in turn, build and test a stuttering prediction model.MethodsA multi-step process including a keyword search of medical notes, a text-mining algorithm, and manual review was employed to identify stuttering cases in the EHR. Confirmed cases were compared to matched controls in a phenotype code (phecode) enrichment analysis to reveal conditions associated with stuttering (i.e., comorbidities). These associated phenotypes were used as proxy variables to phenotypically predict stuttering in subjects within the EHR that were not otherwise identifiable using the multi-step identification process described above.ResultsThe multi-step process resulted in the manually reviewed identification of 1,143 stuttering cases in the EHR. Highly enriched phecodes included codes related to childhood onset fluency disorder, adult-onset fluency disorder, hearing loss, sleep disorders, atopy, a multitude of codes for infections, neurological deficits, and body weight. These phecodes were used as variables to create a phenome risk classifier (PheRC) prediction model to identify additional high likelihood stuttering cases. The PheRC prediction model resulted in a positive predictive value of 83 %.ConclusionsThis study demonstrates the feasibility of using EHRs in the study of stuttering and found phenotypic associations. The creation of the PheRC has the potential to enable future studies of stuttering using existing EHR data, including investigations into the genetic etiology. 相似文献

Perinatal arterial ischemic stroke (PAIS) is a form of childhood stroke; the majority of those affected experience neurologic sequelae, including motor, language and neurocognitive impairments. This study examines the attention and executive functioning (EF) profiles of children following PAIS, as well as the impact of age and sex. In this single-center cross-sectional study, 40 children aged 3 to 16 years (median age 7.2 years; 58% male) who have suffered a PAIS underwent a comprehensive neuropsychological battery to assess attention and EF. Parents completed behavioral questionnaires regarding real-world functioning. Composite scores were calculated for seven attention and EF domains (Attention, Working Memory, Verbal Retrieval, Inhibitory Control, Flexibility/Shifting, Planning/Organization, and Processing Speed). The results for all measured domains of attention and EF are significantly lower in the participants compared to the normative samples (p < .001), with the exception of Working Memory. However, increasing difficulty with Working Memory is associated with developing age. Older age at time of testing is also associated with a higher incidence of clinically-elevated attention deficit hyperactivity disorder (ADHD) symptoms. Sex is not associated with performance measures or parental report of functioning. The participants demonstrate mild-to-moderate attention and EF impairment compared to the normative population. Clinicians, families, and educators should be informed about the neurocognitive sequelae of PAIS and the need for close developmental surveillance in this population to identify vulnerable children and initiate appropriate therapeutic interventions in a timely fashion. 相似文献

ContextAware of the difficulties caused by the COVID-19 pandemic for many families with children aged 6 or under, this study focuses on three contexts of potential vulnerability: single parenthood, children with developmental disorders, poverty.MethodA questionnaire, consisting of 69 questions, was transmitted nationally during the first lockdown (from 17 March to 10 May 2020). Among the study sample (n = 490), 36 households were single-parent, and 93 families had a child with developmental impairments. From November 2020 to June 2021, a additional qualitative approach was used to reach the most vulnerable groups (n = 23).ResultsThe methodology adopted made it possible to identify modes of experience that converge across families in the three contexts (more strengthened intrafamily relationships and investment in protection measures, for example), and others that appear more specific: pressure felt and need for information for single-parent households and those with children with developmental disorders, the burden of home schooling for single-parent households and the poorest, social isolation for single-parent households and difficulties in maintaining the previous food budget for the most precarious.ConclusionThe various pressures felt, the housing (with or without outdoor spaces) and working conditions, the fear of being sick, the negative feelings, etc. must encourage public authorities to implement psychological support mechanisms, particularly for the most vulnerable parents, in order to avoid subsequent physical and/or psychological health problems or even post-traumatic symptoms for parents and their children. 相似文献

Nielsen, T. R. Vogel, A., Gade, A. & Waldemar, G. (2012). Cognitive testing in healthy Turkish immigrants ‐ comparison of the RUDAS and the MMSE. Scandinavian Journal of Psychology 53, 455–460. Methods for culturally and linguistically appropriate cognitive testing of elderly minority populations are lacking in Europe. The aim of this study was to compare performance on the Rowland Universal Dementia Assessment Scale (RUDAS) and the Mini Mental State Examination (MMSE) in Turkish immigrants in Denmark and determine the impact of demographic and health‐related variables on test performance. A sample of non‐demented community‐dwelling Turkish immigrants was recruited from the greater Copenhagen area. All participants completed a structured interview regarding demographic, physical and mental health status, as well as measures of depression and acculturation, and cognitive testing with the RUDAS and the MMSE. A total of 76 non‐demented participants aged 50 or more were included in the study. The mean performance on the RUDAS and the MMSE was 26.8 (SD 2.4) and 23.7 (SD 4.3), respectively. In group comparisons, correlation analyses and regression analyses, level of schooling represented a more significant variable for RUDAS and MMSE performance than any other variable. However, the impact of schooling was considerably more pronounced on the MMSE and the test was not found to be a valid measure of general cognitive function in subjects with less than five years of schooling. Although not entirely free of educational bias, the RUDAS can be a valuable supplement to the MMSE for assessment of general cognitive function in Turkish minority populations. 相似文献

Anoxic brain injury (ABI) often results in severe memory impairment and other cognitive and behavioral deficits, although limited information is available regarding pediatric cases. This study reported the neuropsychological outcomes in six children and adolescents who sustained ABI. Profiles were compared by mechanism of injury (ischemic vs. hypoxemic) and three cases were evaluated more than once. Severe intellectual, attention, memory, and behavioral impairments were observed in all six cases although academic achievement, internalizing behavioral problems, and visuospatial deficits were in general less severe than other cognitive and behavioral deficits. The longitudinal case studies varied but showed steady increases in memory and intellectual performance in the younger children with strongest improvement in nonverbal abilities and little change in parent-reported behavior. This study raises several possible hypotheses about specific cognitive and behavioral outcomes observed in pediatric ABI. 相似文献

The current study focused on the early development of inhibitory control in 5- to 7-year-old children attending kindergarten in two Eastern-European countries, Romania and Russia. These two countries share many aspects of child-rearing and educational practices, previously documented to influence the development of inhibitory control. Using the Lurian-based developmental approach offered by the Developmental Neuropsychological Assessment battery, the study aimed to contribute to cross-cultural developmental neuropsychology by exploring (a) early interrelationships between subcomponents of inhibitory control (response suppression and attention control) and generative fluency (verbal and figural) in these two cultures, as well as (b) the predictive value of external factors (culture and maternal education) and individual differences (age, gender, nonverbal intelligence, trait anxiety) on inhibitory control and fluency outcomes in children from both countries. First, findings in both culture samples suggest that even at this young age, the construct of inhibitory control cannot be considered a unitary entity. Second, differences in maternal education were not predictive of either inhibitory control or fluency scores. However, children’s attention control performance varied as a function of culture, and the direction of these cultural effects differed by whether the target outcome involved performance accuracy versus efficiency as an output. Findings also confirmed the previously documented intensive developmental improvement in preschoolers’ inhibitory control during this period, influencing measures of response suppression and particularly attention control. Finally, the results further stress the importance of individual differences effects in trait anxiety on attention control efficiency across cultures. 相似文献
