This study explores the relation of white matter disorder (WMD) to intralimb coordination patterns in premature infants with very low birth weight (VLBW). We specifically measured the temporal-spatial characteristics of intralimb coordination patterns of the legs. Three groups of infants were compared at one month corrected age (CA): 10 premature infants born VLBW and WMD (PTWMD), 10 premature infants born VLBW without WMD (PT) and 10 full term infants (FT). Using kinematic variables, we discriminate among VLBW infants with WMD from the two comparison groups. Infants born with WMD maintain patterns of tight coupling among leg joints (all flexion or all extension) while PT and FT term infants have begun to decouple leg joints by this age (combinations of flexion with extension). The coupling pattern is captured through joint correlations, discrete relative phase, and phase plane portraits. The PTWMD infants also demonstrate aberrant patterns of coordination evident through both temporal and spatial characteristics of the kicks. This is the first evidence that movement disorder associated with brain lesions can be identified and quantified with kinematic variables as early as one month of age. 相似文献

Parents tend to modulate their movements when demonstrating actions to their infants. Thus far, these modulations have primarily been quantified by human raters and for entire interactions, thereby possibly overlooking the intricacy of such demonstrations. Using optical motion tracking, the precise modulations of parents’ infant‐directed actions were quantified and compared to adult‐directed actions and between action types. Parents demonstrated four novel objects to their 14‐month‐old infants and adult confederates. Each object required a specific action to produce a unique effect (e.g. rattling). Parents were asked to demonstrate an object at least once before passing it to their demonstration partner, and they were subsequently free to exchange the object as often as desired. Infants’ success at producing the objects’ action‐effects was coded during the demonstration session and their memory of the action‐effects was tested after a several‐minute delay. Indicating general modulations across actions, parents repeated demonstrations more often, performed the actions in closer proximity and demonstrated action‐effects for longer when interacting with their infant compared to the adults. Meanwhile, modulations of movement size and velocity were specific to certain action‐effect pairs. Furthermore, a ‘just right’ modulation of proximity was detected, since infants’ learning, memory, and parents’ prior evaluations of their infants’ motor abilities, were related to demonstrations that were performed neither too far from nor too close to the infants. Together, these findings indicate that infant‐directed action modulations are not solely overall exaggerations but are dependent upon the characteristics of the to‐be learned actions, their effects, and the infant learners. 相似文献

Progressive delay training (PDT) has been used to promote self-controlled choices (i.e., selecting a larger, later reward over a smaller, immediate reward) for people with a variety of developmental characteristics. However, the efficacy of PDT has not been evaluated in children with emotional and behavioral disorders (EBD), who often have co-occurring symptoms of impulsivity. The purpose of this study was to evaluate the effects of PDT with a rule-following requirement on the impulsive choices of 6 elementary students with EBD using a modified changing criterion design. Results indicated that PDT alone did not improve self-control, but a modified version of PDT with a rationale and rule for selecting the delayed reward promoted self-control for 3 participants. The remaining 3 participants continued to make impulsive choices despite further modifications to the PDT protocol. We discuss implications of our results and directions for future research on treating impulsivity in children with EBD. 相似文献

In Risk and Rationality, Lara Buchak advertised REU theory as able to recover the modal preferences in the Allais paradox. But we pointed out that REU theory only applies in the “grand world” setting, where it actually struggles with the modal Allais preferences. Buchak offers two replies. Here we enumerate technical and philosophical problems they face.

Individuals with anxiety and depressive symptoms exhibit disturbances in positive emotion regulation, which may hinder full recovery. By comparison, individuals with strong beliefs regarding their capacity to “savor” or maintain positive emotions (i.e., savoring beliefs) display more adaptive positive emotion regulation. The present daily diary study explores three momentary processes involved in positive emotion regulation, namely positive emotion reactivity, regulatory goals, and regulatory effectiveness, and examines the comparative effects of baseline anxiety and depressive symptoms versus savoring beliefs on such processes in real-life contexts. A sample of 164 nonclinical undergraduates provided baseline measures of anxiety and depressive symptom severity and savoring beliefs prior to completing 14 daily assessments of positive emotions and emotion regulatory responses to daily positive events. Results indicated that higher baseline anxiety and depressive symptom severity were associated with decreased positive emotion reactivity and increased down-regulation of positive emotions; higher baseline savoring beliefs were associated with increased positive emotion reactivity, decreased down-regulation and increased up-regulation of positive emotions. Potential clinical implications are discussed. 相似文献

Previous studies on working memory training have indicated that transfer to non-trained tasks of other cognitive domains may be possible. The aim of this study is to compare working memory training and transfer effects between younger and older adults (n = 60). A novel approach to adaptive n-back training (12 sessions) was implemented by varying the working memory load and the presentation speed. All participants completed a neuropsychological battery of tests before and after the training. On average, younger training participants achieved difficulty level 12 after training, while older training participants only reached difficulty level 5. In younger participants, transfer to Verbal Fluency and Digit Symbol Substitution test was found. In older participants, we observed a transfer to Digit Span Forward, CERAD Delayed Recall, and Digit Symbol Substitution test. Results suggest that working memory training may be a beneficial intervention for maintaining and improving cognitive functioning in old age. 相似文献

More women of the National Guard and Reserves have deployed to combat zones overseas than ever before. Upon reintegration, these soldiers often face a number of stressors related to their combat zone experiences and readjustment to civilian life. One of these stressors is the reintegration with family, partners, and children. This qualitative study involved interviews with 30 women from the National Guard regarding their reintegration experiences with their children. Four categories were revealed from the data: (a) Concerns for Children’s Well-being, (b) Sense of Loss (c) Reintegration: Personal Challenges, and (d) Reintegration: Children’s Reactions. Implications for clinical work with returning soldiers and further research are discussed. 相似文献

Moderation of Stimulus Material on the Prediction of IQ with Infants' Performance in the Visual Expectation Paradigm: Do Greebles Make the Task More Challenging? 下载免费PDF全文

The objective of this study was to examine the role of the stimulus material for the prediction of later IQ by early learning measures in the Visual Expectation Paradigm (VExP). The VExP was assessed at 9 months using two types of stimuli, Greebles and human faces. Greebles were assumed to be associated with a higher load on working memory in comparison to human faces. IQ was assessed at 3 years and 4 months of age. Sixty‐four children participated at both assessments in this longitudinal study. The results show a moderation of the stimulus material on the prediction of IQ. With Greebles as stimulus material, a significant relationship between infants' learning and IQ was found. There was no relation when infants' learned in the VExP using human faces. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
