Developmental Characteristics of Disparate Bimanual Movement Skills in Typically Developing Children
Julian Rudisch Jenny Butler Hooshang Izadi Deirdre Birtles Dido Green 《Journal of motor behavior》2018,50(1):8-16
Mastery of many tasks in daily life requires role differentiated bimanual hand use with high spatiotemporal cooperation and minimal interference. The authors investigated developmental changes in the performance of a disparate bimanual movement task requiring sequenced movements. Age groups were attributed to changes in CNS structures critical for bimanual control such as the corpus callosum (CC) and the prefrontal cortex; young children (5–6 years old), older children (7–9 years old), and adolescents (10–16 years old). Results show qualitative changes in spatiotemporal sequencing between the young and older children which typically marks a phase of distinct reduction of growth and myelination of the CC. Results show qualitative changes in spatiotemporal sequencing between the young and older children, which coincides with distinct changes in the growth rate and myelination of the CC. The results further support the hypothesis that CC maturation plays an important role in the development of bimanual skills. 相似文献

The present study investigates the effects of word category (nouns versus verbs) and their subcategories on naming latencies in German, with a focus on the influence of lexical parameters on naming performance. The experimental material met linguistic construction criteria and was carefully matched for age of spontaneous production, frequency, and name agreement. Additional lexical parameters (objective age-of-acquisition, word length, visual complexity, imageability) were obtained. The results demonstrated a clear effect of word category on naming latencies. This effect was supported by two different observations. First, there was evidence for category and subcategory effects in naming: nouns were named faster than verbs, and intransitive verbs were named faster than transitive verbs. Second, while objective age-of-acquisition (naming age) turned out to be an important predictor of reaction times for both word categories, naming latencies for nouns and verbs were affected differentially by other lexical parameters. The results are discussed with respect to current controversies on the noun-verb-asymmetry. 相似文献

Agrammatism is-among others, characterized by a deficit in producing grammatical structures. Of specific difficulty is the utilization of complex, non-canonical sentence structures (e.g. object-questions, passives, object-clefts). Several studies have documented positive effects when applying a specific treatment protocol in terms of increasingly correct production of target complex sentence structures with some variance in generalization patterns noted across individuals. The objective of this intervention study was to evaluate an intervention program focussing on the production of non-canonical sentences. Hypotheses about the occurrence of treatment effects were formulated on the basis of syntactic complexity, referring to the amount of syntactic phrase structures necessary to generate specific German sentence structures. A multiple single case study with seven agrammatic participants was applied, each participant receiving training in the production of object-relative-clauses and who-questions. The investigation was designed to unambiguously evaluate for each individual, structure specific and generalized learning effects with respect to the production of object-relative-clauses, who-questions and passive sentences. Results showed significant improvements for all sentences types. This outcome is considered within methodological issues of treatment studies. Theoretical and clinical implications are discussed. 相似文献

This study conducted an up-to-date assessment of situational and interpersonal risk factors for sexual aggression. Two hundred undergraduate women from a medium sized college on the US west coast completed the Sexual Experiences Survey (SES) and a questionnaire developed by the authors. Participants who reported sexual victimization on the SES answered a series of questions about their most severe experience, as well as a representative, nonaggressive date. Participants who reported no sexual victimization answered questions only about a representative date. Risk factors were identified by comparing victimized participants’ sexually aggressive dates to nonvictimized participants’ dates, and victimized participants’ non-sexually aggressive dates to nonvictimized participants’ dates. Results revealed distinct situational and interpersonal differences between sexually aggressive and nonaggressive social interactions. 相似文献

The aim of this study is to explore reasons for and against prenatal testing and termination for a range of conditions in
women from two different ethnic backgrounds. A total of 19 Pakistani and European women in West Yorkshire, UK, who either
had a child with a genetic condition or had terminated a pregnancy for one, completed a questionnaire about their attitudes
regarding prenatal testing and termination for 30 different fetal conditions and were interviewed about their reasons for
their responses. There were more similarities than differences between the Pakistani and European white women. The most important
factor in most women’s decisions about termination of pregnancy was their perception of the quality of the life of a child
with the genetic condition, in particular, whether the child would be “suffering.” This was described as either physical suffering,
as a result of medical treatment, or as emotional suffering, as a result of psychological and/or social factors. These findings
highlight the need for detailed information about the potential quality of life for the child and the child’s family to enable
parents to make informed choices, particularly the extent to which the child is likely to suffer, the nature of such potential
“suffering” and the extent to which the child could lead a “normal” life. The findings also challenge stereotypes about cultural
differences in attitudes about termination of pregnancy. 相似文献

How do listeners learn about the statistical regularities underlying musical harmony? In traditional Western music, certain chords predict the occurrence of other chords: Given a particular chord, not all chords are equally likely to follow. In Experiments 1 and 2, we investigated whether adults make use of statistical information when learning new musical structures. Listeners were exposed to a novel musical system containing phrases generated using an artificial grammar. This new system contained statistical structure quite different from Western tonal music. Our results suggest that learners take advantage of the statistical patterning of chords to acquire new musical structures, similar to learning processes previously observed for language learning. 相似文献

This article provides a phenomenological analysis of the difference between self-recognition and recognition of another, while
referring to some contemporary neuroscientific studies on the rubber hand illusion. It examines the difference between these
two forms of recognition on the basis of Husserl’s and Merleau-Ponty’s work. It argues that both phenomenologies, despite
their different views on inter-subjectivity, allow for the specificity of recognition of another. In explaining self-recognition,
however, Husserl’s account seems less convincing. Research concerning the rubber hand illusion has confirmed that self-recognition
involves more than an immediate experience of oneself. Merleau-Ponty’s later work, describing self-recognition as the result
of assimilative identification, will be used to explain the possibility of illusion between one’s “hereness” and “thereness”.
The possibility of this illusion is inherent to self-recognition, while it is lacking in recognition of another.
