Developmental changes in the kinematics and kinetics underlying balance control were studied in 61 children, 9 months to 10 years of age. The children were classified according to developmental milestones as standers; new, intermediate, and advanced walkers; runners-jumpers; hoppers; gallopers; and skippers. The children experienced support-surface translations of varying size and speed. Children with greater locomotor experience withstood larger balance threats without collapsing or stepping. Analyses of scaled trials (perturbations normalized in size to foot length and center of gravity height) revealed that improvement in balance was not related to initial configuration parameters surrounding the task (degree of crouch or lean). Children with advanced locomotor skills had faster recovery times and relatively larger muscle torques than children with less experience. Relative torque-time histories of the more experienced children began to match the adult response to similar perturbations. With increased experience and changing muscle torque regulatory abilities, balance skills became more robust. 相似文献

The relationship between suicide and birthdays, and suicide and public holidays has been studied from data on 32,291 Danish suicides by persons ages 15 years and older in the 25-year period 1970-1994. Evidence was found to support the theory of the "broken-promise effect" for major public holidays in that there appears to be a postponement of a significant number of suicides from before a holiday until after. The division of holidays into nonworking and (half-time) working days showed that a "holiday effect" could only be found around major public holidays, particularly Christmas, Easter, and Whitsun. The postponing or transpositioning effect is relevant to prevention, especially because of the availability and accessibility of help at the end of and after major public (nonworking) holidays. 相似文献

In this study, we examined a theoretical model of self-development and a scale to measure 12 aspects of the self. The theory, called developmental self-theory, proposes a hierarchical arrangement of dimensions of the self. The 12 scales are collectively called the Omnibus Self-Test and measure Self-Esteem, Positive Self-Regard, Moral Self-Concept, Self-Confidence, Self-Reliance, Self-Control, Selfishness, Self-Disclosure, Self-as-Agent, Self-Critical, Self-Identity, and Self-Reflection. Preliminary data on the reliability and validity of the Omnibus Self-Test is reported along with intercorrelations among the scales. 相似文献

Rats were used to determine whether stress-induced analgesia (SIA) can be produced by conditioning with interoceptive stimuli (LiCl) as with exteroceptive stimuli (footshock). SIA was measured using a tail-flick test. As expected, unavoidable footshock as well as conditioning with footshock produced SIA. In contrast, conditioning with LiCl failed to cause SIA. The findings support the notion of functional differences in neural substrates for conditioning by exteroceptive and interoceptive cue. 相似文献

A variety of predictors of parent participation in prevention programming have been identified in past research, but few studies
have investigated how those predictors may vary by implementation context. Patterns of parent participation were examined
in the Early Risers Conduct Problems Prevention Program using two family-focused service delivery models: a community center
model (Center) and an in-home outreach-based model (Outreach). An ethnically diverse sample of Kindergarten through second
grade students (n = 246) displaying elevated levels of aggression were recruited for the study and randomly assigned to either
the Center (n = 121) or Outreach (n = 125) models. In both delivery models, participants and their families completed an assortment
of baseline measures and received family skills and child skills intervention components and family- and school-based case
management. Parents in the Center model demonstrated greater overall participation in family-focused components of the intervention.
Parent motivation with parent-focused expectancies for the intervention represented the strongest predictor of parent participation
across both delivery models. Family income differentially predicted parent participation across the two models, with low income
predicting greater participation in the Center model and lower participation in the Outreach model. A qualitative finding
emerged showing that parents receiving parent skills in the Center model via groups preferred to learn skills related to facilitating
overall family relationships, whereas parents receiving parent skills via individual Outreach meetings preferred to improve
a child’s behavior and emotion skills. Implications are discussed for the design of prevention programming in order to maximize
parent participation in high risk populations. 相似文献

Though previous research suggests that attendance at individual therapy is not impacted by amount or source of payment for services, such research is relatively sparse and clinician concerns remain. The present study explores the connection between payment of fees and attendance at group treatments--a previously unexplored area. Participants in a 10-week behavioral parent training (BPT) program varied in timing of payment of fees as well as amount of fees based on income. The varying payment schedules did not affect attendance to sessions at which payments were due nor did payment schedules affect completion of the program. A small relationship was found between income group and attendance. The results are discussed in their relation to the larger literature on fees and attendance at psychotherapy. 相似文献

Purpose: Although the content of thoughts has received a considerable amount of attention in pain research, the importance of thought processes (metacognitions) has received less attention. Method: One hundred twenty-nine individuals with muscular dystrophy and chronic pain completed measures assessing metacognitions and frequency of both catastrophizing and pain control beliefs. Results: Greater use of reappraisal and distraction metacognitions were associated with more perceived control over pain, whereas greater use of worry and punishment metacognitions were associated with more catastrophizing. Conclusions/Implications: The current findings indicate that metacognitions are associated with both pain control beliefs and catastrophizing and therefore may play an important role in the development or maintenance of pain-related cognitive content thought to influence patient functioning. Research is needed to determine whether treatments that encourage changes in both metacognitions and cognitive content are more effective than treatments that focus on cognitive content alone.

Predicting counterproductive work behavior from the interaction of personality traits 总被引:1,自引:0,他引:1
Much attention has been given to enhancing the prediction of counterproductive work behavior (CWB), with a particular focus on the relationship between the five factor model of personality and CWB. Several scholars have advocated for a more complex view of this relationship, and rather than focusing simply on main effects, to examine the interaction of personality traits in predicting employee behavior. In consideration of the traits most strongly related to CWB, we examined the interaction between: (1) conscientiousness and emotional stability, (2) agreeableness and emotional stability, and (3) conscientiousness and agreeableness on CWB directed at individuals (CWB-I) and the organization (CWB-O). Results from a multi-national sample illustrate the interaction of traits increases the prediction of CWB over and above a single trait approach. The interactions suggest employees perform the least CWB when they are high on both traits (in the respective trait pairings), but low levels on either trait relate to increased CWB, and at levels comparable to individuals low on both traits. We conclude research on personality and CWB would benefit from an interactive approach as it allows for greater prediction of CWB-O and CWB-I, which is important in light of the organizational and interpersonal consequences of employee misbehavior. 相似文献
