In the past, the nature of the compositional units proposed for spoken language has largely diverged from the types of control units pursued in the domains of other skilled motor tasks. A classic source of evidence as to the units structuring speech has been patterns observed in speech errors--"slips of the tongue". The present study reports, for the first time, on kinematic data from tongue and lip movements during speech errors elicited in the laboratory using a repetition task. Our data are consistent with the hypothesis that speech production results from the assembly of dynamically defined action units--gestures--in a linguistically structured environment. The experimental results support both the presence of gestural units and the dynamical properties of these units and their coordination. This study of speech articulation shows that it is possible to develop a principled account of spoken language within a more general theory of action. 相似文献

Parent delivered interventions based on applied behavior analysis (ABA) for children with Pervasive Developmental Disorders (PDDs) have been evaluated using primarily single‐subject design methodology or small case series. While the results of these evaluations are encouraging, an important next step is to standardize the interventions to allow for replication across sites, in studies with large samples and measures of long‐term, clinically meaningful outcomes such as improvements in children's functioning and their relationships with parents. Accordingly, the Research Units on Pediatric Psychopharmacology and Psychosocial Interventions (RUPP Autism Network) assembled a detailed manual for a structured behavioral parent training (PT) program, developed treatment fidelity and training procedures, and conducted a pilot, feasibility study. The PT program is part of a large scale, multisite study intended to determine the efficacy of combined pharmacological treatment and behavioral intervention to improve behavior and adaptive functioning in children with PDD. This paper discusses the rationale for this project. A companion paper provides the results of our feasibility study on the PT program. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Neuroimaging studies have shown the involvement of prefrontal and posterior parietal cortexes in regulating information processing.
We conducted behavioral and fMRI experiments to investigate the relationship between memory selection and proactive interference
(PI), using a delayed recognition task with a selection cue presented during the delay indicating which two of the four studied
digits were relevant to the present test. PI was indexed by the response time differences between rejecting probes matching
and not matching the no longer relevant digits. By varying the delay intervals, we found that the effect of PI did not diminish,
even for cases in which the postcue interval was extended to 9 sec, but was stronger when the precue interval was lengthened
to 5 sec. By examining the correlation between PI index and neural correlates of memory selection, we found that stronger
PI is predicted by lower selection-related activity in the left inferior parietal lobe, the precuneus, and the dorsal middle
frontal gyrus. Our results suggest that activity in the prefrontal-parietal network may contribute to one’s ability to focus
on the task-relevant information and may proactively reduce PI in working memory. 相似文献

This study examined parenting of mothers and fathers of 3-year-old children who were classified as hyperactive (HYP), hyperactive and oppositional defiant (HYP/OD), and non-problem based on mothers' reports of behavior. Parents of children with HYP/OD were less warm, showed more negative affect, and more laxness than parents of non-problem children; however, contrary to prediction, they did not differ significantly from parents of children in the HYP group. Compared to mothers of non-problem children, mothers of children in the HYP/OD group reported significantly more parenting stress across all domains, whereas mothers of children in the HYP group only reported elevated levels of stress associated with having a difficult child. Theoretical and treatment implications are discussed. 相似文献

This study examined 3-year-old children who were classified as hyperactive (HYP), oppositional-defiant (OD), hyperactive and oppositional defiant (HYP/OD), and non-problem based on mothers' reports of behavior. Using fathers,' teachers,' and observers' ratings of children's behavior, concurrent validity was excellent for the HYP/OD group, moderate for the HYP group, and poor for the OD group. As predicted, both the HYP/OD and HYP groups reported more prenatal/perinatal birth complications and a greater family history of hyperactivity than did non-problem children. Furthermore, the HYP/OD group showed a greater family history of conduct disorder and oppositional defiant disorder (ODD) symptoms than did non-problem children; however, the HYP group also showed a greater family history of ODD than did non-problem children. Results suggest that as early as age 3, these behavior subtypes appear to be linked to biologically-based risk-factors in ways that are consistent with theories of the development of ADHD. 相似文献

Two studies show that initial expectancies influence the way people respond toward task-related differences (i.e., in work goals or work styles) between the self and a collaboration partner. When no advance information is available, participants expect their partner to be similar to themselves in task-related aspects. However, when people expect their partner to have a different work goal (Study 1) or work style (Study 2), and this actually is the case, disappointment is reduced and commitment toward future collaboration is increased. Initial expectations are important because these help people develop a clear picture of their partner. When initial expectations are violated, people conceive the other less clearly and this is part of the reason they report lower levels of commitment. 相似文献
