The purpose of this study was to assess neurological soft signs in children and adolescents with isolated cleft of the lip or palate (iCL/P) compared with healthy controls. Children with iCL/P were recruited through the university cleft clinic. Control subjects were recruited through advertisements. Of the 166 subjects who participated (age range 7 to 17 years, M = 12.5, SD = 3.2), 77 had iCL/P (48 male) and 89 were healthy controls (44 male). All participants took the Physical and Neurological Examination of Subtle Signs and selected tests of motor coordination. A multivariate analysis of variance assessed differences between subjects with and without iCL/P. Also, a Pearson correlation estimated the relationship between the neurological soft signs and age. Subjects with iCL/P scored significantly higher on all neurological soft signs variables. These higher scores were associated with younger age. Findings lend support to the hypothesis of aberrant brain development in children with iCL/P.  相似文献

We examined developmental aspects of the ability to monitor the temporal context of an item’s previous occurrence while event‐related potentials (ERPs) were recorded. In a continuous recognition task, children between 10 and 12 years and young adults watched a stream of pictures repeated with a lag of 10–15 intervening items and indicated recurrences. In a second run, these already familiar pictures were repeated as non‐targets along with new pictures, while subjects were instructed to indicate only recurrences within the run. Young adults were able to maintain high performance levels in both tasks, whereas children had longer response times and committed a large number of false alarms to non‐targets. ERPs in both age groups showed similar parietal old/new effects for target repetitions within runs. In addition, adults’ ERPs showed similar old/new effects at frontal electrodes for repetitions and non‐targets, presumably reflecting assessments of familiarity, whereas for children repeated relative to first presentations were associated with more negative‐going waveforms at anterior frontal recording sites. Together, these results suggest a continuing maturation of the brain networks assessing novelty or familiarity. Recollection as indexed by parietal old/new effects appeared similar between young adults and children, but the development of controlled episodic retrieval, resulting in recollection of non‐target information, appears to continue well into adolescence.  相似文献

In the present investigation we conducted three studies to examine how unconscious valence processing influences participants' quality judgments in an attribute-framing task. In Studies 1 and 2 we observed how individuals who had depleted cognitive resources, through distraction (Study 2) and time constraint (Study 3), differed in their responses to an attribute-framing task. In Study 3 we subliminally primed participants with attribute frames and then presented them with a frameless decision task. Our results revealed that attribute framing arises from unconscious valence processing and conscious processing may only play a role when the frame is especially salient.  相似文献

The cognitive-behavioural group training for social competence “GSK” [16] has proven to also be effective in the penal system [28]. The present study examines if a targeted differentiating assessment prior to the intervention and a thereon based homogeneous group composition with regard to insecure and aggressive behaviour patterns can enhance the effectiveness of the “GSK” in the penal system and in a forensic hospital unit. Altogether 48 male delinquents across both settings were therefore divided into a “homogeneous insecure” group, a “homogeneous aggressive” group and a “heterogeneous” group. Pre-post-comparisons show that the intervention is effective for all three groups and also in both settings, the penal system and the forensic hospital unit. The “homogeneous aggressive” group revealed the strongest intervention effects.  相似文献

Expectations of controllability are thought to influence subsequent behaviour, such that perceived non-contingency between behaviour and outcomes can produce a “learned helplessness” reaction by the organism. Since cognitive processes are implicated in this debilitation, the present study examines the influence of manipulated controllability upon the intrinsic individual differences (among females) in a disjunctive conceptual behaviour recovery task. Three-mode factor analysis is used to explore the process variability in a multivariate time-series design. Results indicate that intrinsic task processes are altered by the controllability pretreatment, but the nature of the impact reflects substantial individual differences in reaction.  相似文献

Thirteen social isolates were selected from five nursery schools according to teacher ratings and behavioral samples obtained by trained observers. Half the subjects were randomly assigned to a modeling group and viewed a 23-minute film depicting appropriate social behavior in the nursery school. The remainder of the subjects viewed the same film, but also received 2 days of teacher praise contingent on the subject's peer interaction in his classroom. Modeling was inferred to successfully modify isolate behavior with or without praise. The modeling plus praise condition was not significantly different from modeling only for children's social interactions. General proximity response scores appeared to be detrimentally affected by the praise contingency during posttest assessment only. At followup, all subjects maintained or improved their posttest interaction scores.Gratitude is expressed to the administrators and teachers at the Jewish Community Center of Syracuse and the Syracuse University Cooperative Nursery School.  相似文献

Three experiments investigated the influence of positive and negative affect manipulations on children's preferences for small immediate versus large delayed rewards. Positive and negative affect were induced via verbal instructions to imagine happy and sad experiences. Elementary school children were randomly assigned to a control condition or to one of several treatment conditions consisting of two affect manipulations: a positive followed by a negative, the reverse, and (in the third experiment) two positives or two negatives. In some conditions (in the second and third experiments) measurement of delayed reward preference followed the first and second affect inductions whereas in other conditions (in the second and third experiments) measurement followed only the second affect manipulation. As predicted, negative affect subjects chose fewer large delayed rewards than did positive affect subjects during the first assessment (p < .02). At the second assessment, comparison among treatment and control conditions revealed the influence of a prior commitment effect which negated the potential influence of a second affect manipulation on preference for delayed rewards.  相似文献
