The purpose of this experiment is to test whether shift flexibility in kindergarten children is a joint function of rule‐usage and inhibition of attention. Sixty‐six children were given either a distraction or facilitation condition in a computerized version of the dimensional change card sort task. In the distraction condition, the background of the post‐shift matching stimulus was inconsistent with the relevant matching dimension. In the facilitation condition, the background of the post‐shift matching stimulus was consistent with the relevant matching dimension. Results revealed that children made few errors in the standard version of the shift task, thereby supporting Cognitive complexity and control theory's contention that 5‐year‐old children shift easily across dimensions due to their use of higher‐order setting rules to solve contradictions. The proportion of errors increased however in the distraction condition suggesting that attention to the background interfered with children's ability to shift between dimensions. Therefore, these data provide evidence that refocusing attention to dimensions along with rule‐use processes affect shift flexibility and argue for the inclusion of both factors into theoretical accounts of shift performance.

This study evaluated video scoring and feedback about scoring as a safety intervention among 6 nursing staff. The dependent variable was safety behavior on one‐person transfers. Following baseline, 5 nursing staff participated in an information phase. A video scoring phase was then introduced for all 6. A feedback phase was added for 2 participants. All participants experienced treatment withdrawal. Information resulted in improvements for all 5 participants who received it. Further improvements were observed during video scoring for the 5 participants who improved following information. No improvements were observed for the participant who received only video scoring. Safety feedback further improved safety for the 2 participants who received it. However, participants' behavior returned to video scoring levels during withdrawal. 相似文献

Acceptance and Commitment Therapy (ACT) is an innovative acceptance-based behavior therapy that has been applied broadly and successfully to treat a variety of clinical problems, including the anxiety disorders. Throughout treatment ACT balances acceptance and mindfulness processes with commitment and behavior change processes. As applied to anxiety disorders, ACT seeks to undermine excessive struggle with anxiety and experiential avoidance––attempts to down-regulate and control unwanted private events (thoughts, images, bodily sensations). The goal is to foster more flexible and mindful ways of relating to anxiety so individuals can pursue life goals important to them. This article describes in some detail a unified ACT protocol that can be adapted for use with persons presenting with any of the major anxiety disorders. To exemplify this approach, we present pre- and posttreatment data from three individuals with different anxiety disorders who underwent treatment over a 12-week period. The results showed positive pre- to posttreatment changes in ACT-relevant process measures (e.g., reductions in experiential avoidance, increases in acceptance and mindfulness skills), increases in quality of life, as well as significant reductions in traditional anxiety and distress measures. All three clients reported maintaining or improving on their posttreatment level of functioning. 相似文献

The health of clergy is important, and clergy may find health programming tailored to them more effective. Little is known
about existing clergy health programs. We contacted Protestant denominational headquarters and searched academic databases
and the Internet. We identified 56 clergy health programs and categorized them into prevention and personal enrichment; counseling;
marriage and family enrichment; peer support; congregational health; congregational effectiveness; denominational enrichment;
insurance/strategic pension plans; and referral-based programs. Only 13 of the programs engaged in outcomes evaluation. Using
the Socioecological Framework, we found that many programs support individual-level and institutional-level changes, but few
programs support congregational-level changes. Outcome evaluation strategies and a central repository for information on clergy
health programs are needed. 相似文献

Visuomotor sequence learning requires participants to learn a two-fold process of learning the correct visuomotor transformation
(spatial or arbitrary rules) and learning the correct order of performing the sequence. A motor sequence is performed with
a specific timing pattern by grouping a number of elementary movements into chunks. The present research extends previous
findings examining whether chunking phenomenon is observable for visuo-motor sequences with arbitrary transformations in addition
to spatially defined targets. This research tests for dominant chunking patterns and individual variability. 相似文献

This study examined how self-relevant failure influences error monitoring—as reflected in the error-related negativity (Ne/ERN)
—and behavioral adaptation during subsequent feedback-based learning. We applied two phases (pre- and posttest) of a probabilistic
learning task. Between pre- and posttest, participants were assigned to one of two groups receiving either failure feedback
or no feedback during a visual search task described as diagnostic of intellectual abilities. To disentangle the effects of
failure and motivational disengagement due to prolonged task performance, we linked the posttest to intelligence (Experiment
1) or described it in neutral terms (Experiment 2). Failure induction was associated with an increase in Ne/ERN amplitude at posttest in both experiments, although there were
no differences in overall performance. In contrast, the Ne/ERN decreased from pre- to posttest in the no-failure-feedback
group, particularly in Experiment 2. Furthermore, failure feedback affected error-related behavioral adjustments, suggesting a shift toward a reactive, error-driven
mode of behavior control. These findings emphasize the importance of affective-motivational state in error processing and
subsequent behavioral adaptation. 相似文献

So far no known measure of confirmation of a hypothesis by evidence has satisfied a minimal requirement concerning thresholds
of acceptance. In contrast, Shogenji’s new measure of justification (Shogenji, Synthese, this number 2009) does the trick.
As we show, it is ordinally equivalent to the most general measure which satisfies this requirement. We further demonstrate
that this general measure resolves the problem of the irrelevant conjunction. Finally, we spell out some implications of the
general measure for the Conjunction Effect; in particular we give an example in which the effect occurs in a larger domain,
according to Shogenji justification, than Carnap’s measure of confirmation would have led one to expect. 相似文献

One of the chief concerns of the young Descartes was with what he, and others, termed “physico-mathematics”. This signalled
a questioning of the Scholastic Aristotelian view of the mixed mathematical sciences as subordinate to natural philosophy,
non explanatory, and merely instrumental. Somehow, the mixed mathematical disciplines were now to become intimately related
to natural philosophical issues of matter and cause. That is, they were to become more ’physicalised’, more closely intertwined
with natural philosophising, regardless of which species of natural philosophy one advocated. A curious, short-lived yet portentous
epistemological conceit lay at the core of Descartes’ physico-mathematics—the belief that solid geometrical results in the
mixed mathematical sciences literally offered windows into the realm of natural philosophical causation—that in such cases
one could literally “see the causes”. Optics took pride of place within Descartes’ physico-mathematics project, because he
believed it offered unique possibilities for the successful vision of causes. This paper traces Descartes’ early physico-mathematical
program in optics, its origins, pitfalls and its successes, which were crucial in providing Descartes resources for his later
work in systematic natural philosophy. It explores how Descartes exploited his discovery of the law of refraction of light—an
achievement well within the bounds of traditional mixed mathematical optics—in order to derive—in the manner of physico-mathematics—causal
knowledge about light, and indeed insight about the principles of a “dynamics” that would provide the laws of corpuscular
motion and tendency to motion in his natural philosophical system. 相似文献

A recent study [Keri, S., & Benedek, G. (2009). Visual pathway deficit in female fragile × premutation carriers: A potential endophenotype. Brain and Cognition, 69, 291–295] has found Vernier acuity deficiencies together with contrast sensitivity defects consistent with a magnocellular deficit in female fragile × premutation carriers. This may appear to support the notion that Vernier acuity may serve as a test of magnocellular sensitivity. However, Vernier acuity deficiencies have been reported in other conditions (e.g., schizophrenia, amblyopia and cortical visual impairment) where there is little evidence for magnocellular deficits. The observation that Vernier acuity deficiencies can occur without magnocellular deficits indicates that Vernier acuity is not a reliable test of magnocellular sensitivity. 相似文献
