Complex motor learning, but not mere motor activity, has been previously shown to induce structural modifications within the cerebellar cortex. The present experiment examined whether similar changes occur within one of the primary output targets of the region of the cerebellar cortex in which these structural changes were described, the lateral cerebellar nucleus (LCN; dentate nucleus). Adult female rats were randomly allocated to one of three training conditions. Acrobatic condition (AC) rats were trained to complete a complex motor learning task consisting of a series of elevated obstacles while motor control (MC) condition animals were forced to traverse a flat obstacle-free runway equal in length to the AC task. Inactive condition (IC) animals received no motor training. Unbiased stereological techniques and electron microscopy were used to obtain estimates of synapse number and postsynaptic density (PSD) length within the LCN. Results showed that neither synapse number nor PSD length was significantly altered as a function of training condition. These results indicate that complex motor skill learning is associated with structural plasticity within the cerebellar cortex and with structural stability within the lateral cerebellar nucleus. 相似文献

Forty college students were taught facilitated communication via a commercially available training videotape. They were then asked to facilitate the communication of a confederate, who was described as developmentally disabled and unable to speak. All 40 participants produced responses that they attributed at least partially to the confederate, and most attributed all of the communication entirely to her. Eighty-nine percent produced responses corresponding to information they had received, most of which was unknown to the confederate. Responding was significantly correlated with simple ideomotor responses with a pendulum and was not affected by information about the controversy surrounding facilitated communication. These data support the hypothesis that facilitated communication is an instance of automatic writing, akin to that observed in hypothesis and with Ouija boards, and that the ability to produce automatic writing is more common than previously thought. 相似文献

As Lutherans and Pentecostals begin an official international dialogue, the author, a Lutheran member of the dialogue, responds to two related sets of questions raised by a Pentecostal member of the dialogue during a preceding six‐year consultation between these traditions: whether there is a place in the Lutheran tradition for a “theology of glory,” considering the centrality of “a theology of the cross” for Luther; and how Lutherans speak about experiencing the presence of God, and the means through which one encounters God. 相似文献

The Wender Utah Rating Scale (Ward, Wender, &; Reimherr, 1993) has been widely used in adult attention-deficit/hyperactivity disorder (ADHD) research to assess childhood symptoms retrospectively, but little research has examined its factor structure and specificity in predicting ADHD versus other psychopathology. Consequently, this study had 2 goals: (a) to examine the Wender Utah Rating Scale's structure, and (b) to explicate the construct validity of this measure by relating factors from our structural analyses to other ADHD, psychopathology, and personality measures. Structural analyses in an adult community sample (N = 294) yielded a 3-factor structure of aggression (e.g., angry), internalizing distress (e.g., depressed), and academic difficulties (e.g., underachiever). Correlational and regression analyses indicated that these factors failed to display specificity in their associations with ADHD versus other psychopathology. Aggression and internalizing distress associated most strongly with indicators of externalizing (e.g., ill temper, manipulativeness) and internalizing psychopathology (e.g., depression, anxiety), respectively. Academic difficulties associated most strongly with ADHD symptoms, but these relations were relatively weak. Taken together, these findings raise concerns about the Wender Utah Rating Scale's construct validity, although additional longitudinal research is needed to clarify to what extent the Wender Utah Rating Scale validly assesses childhood ADHD symptoms. 相似文献

The purpose of this research was to better understand the substance use and sexual risk taking behavior among high-risk adolescent populations placed in residential treatment facilities, including those in the foster care and juvenile justice systems. The primary predictors considered in this study included caregiver support, caregiver closeness, other adult support, adolescent self-disclosure/communication with caregiver, caregiver expectations about sexual behavior, and peer influence regards to drugs/alcohol and sexual behavior. Participants included 120 adolescent females in grades 7 to 12 (median grade?=?10; mean age 15.7 years), primarily African American (57.2 %) and White (29 %), in a residential treatment setting in a large urban area in the Midwest. Caregiver support and self-disclosure/communication with caregivers predicted condom use at most recent intercourse, but variables related to substance use were most consistently predictive of sexuality variables including onset and frequency of behavior. None of these support variables significantly predicted onset and frequency of substance use. Caregiver support was the contributing variable in predicting academic achievement. 相似文献

Fly-in fly-out work patterns have become an integral part of employment in the Australian resource sector. When attachment to parents is disrupted by a parent working away from home on a regular basis, young people’s feelings of connection to their family may be impacted, as well as their mental and emotional well-being compromised. The objective of this study was to explore the mediation of parental presence and family connectedness on the association between fly-in fly-out employment and adolescent well-being. A cross-sectional survey of over 3,000 Grades 5–10 students from 40 Perth West Australian metropolitan and rural schools identified 618 students whose parents were involved in fly-in fly-out employment. Multi-level mediation analysis showed that the negative relationship between fly-in fly-out status and adolescent depressive symptoms and emotional and behavioural difficulties was fully or partially mediated by parent presence and family connectedness, controlling for both student and school level demographics. The intermittent absence/presence of fly-in fly-out employment patterns appears to create challenges for workers and their families, not experienced by non-fly-in fly-out families.This study highlights the importance of strengthening family connections within fly-in fly-out households. Suggestions have been made to help fly-in fly-out parents to stay in touch with their families. 相似文献
