The Department of Veterans Affairs (VA) requires that all VA hospitals and clinics provide access to evidence-based psychotherapies (EBPs). Despite these widespread dissemination efforts, only a minority of Veterans receive EBP services. Reasons for these low rates of EBP utilization are largely unknown. This study examined the characteristics of Veterans with posttraumatic stress disorder (PTSD) who did (Initiation group) and did not (No-Initiation group) initiate a VA-approved EBP after participating in an information session. Veterans chose their preferred treatment from a menu of EBPs. Results demonstrated that Veterans in the No-Initiation group had longer periods of time between their referral and first EBP visit. Among Veterans in the Initiation group, the majority (68%) initiated a trauma-focused EBP as their first or second treatment, suggesting that providing a range of treatment options did not negatively impact their willingness to engage in PTSD treatment. Results are discussed in terms of VA initiatives to improve access to and initiation of mental health care for Veterans. 相似文献

Whereas Hirsh and Sherrick (1961) found that experienced Os could judge correctly the temporal order of a sound and a light presented repeatedly when the interval separating them was 20 msec, Hirsh and Fraisse (1964) found that naive Os required about 60 msec for the same accuracy of performance with single presentations of the same pair. This experiment examined the effects of single vs repeated presentations, practice, and verbal feedback on performance in the judgment of temporal order. The results indicate that performance under repeated presentation is significantly better than under single presentation, that learning effects are most pronounced during the first 4 of 16 sessions, and that the effects of feedback appear to depend on the precise wording given the S on how he is to perform. 相似文献

The prediction has been tested that under the influence of an anaesthetic drug, nitrous oxide, cognitive performances undergo differential impairment, the extent of which is positively correlated with the “complexity” of the task, Ten kinds of performance were investigated, ranging from speed of finger tapping to reasoning by analogy. The relative complexity of each task was determined, in accordance with conventional criteria, from its respective qualitative category or “level”—relational, associative, and motor—and within each category from qualitative analysis of the component processes involved in its execution. A simple group difference design was used, involving two groups of 50 subjects each, matched for age and sex.
Significant deterioration as a consequence of drug administration occurred in the performance of all tasks. On the whole, the more complex a task the more did it tend to be impaired. Motor performances were, however, impaired to a greater extent than had been predicted. The possible significance of these findings is discussed. 相似文献

Contextual conditions affect behavior in 2 ways: (a) They confront people with opportunities and obstacles that affect their motivation to take action; or (b) they instantaneously shape performance, regardless of a person's motivation and even without subjective acknowledgment of the conditions. Traditionally in psychology, the immediate behavioral consequences of a context are disregarded. Based on our theory of goal‐directed behavior, we are able to disentangle the instant and the motivational behavioral consequences of contexts. In an example study, 40% of the variation in performance among 660 Swiss and Spanish pupils was explained by motivational differences. Instantaneous constraints and facilitations imposed on people's acts, in turn, revealed a set of Switzerland‐ and Spain‐specific limitations and affordances (hit rate = 97.5%). 相似文献

What changes in brain activity are associated with changes in motivational state? The present study addressed this question by having participants perform a cognitive task (AX variant of the Continuous Performance Test; AX-CPT) under three different blocked motivational conditions (reward-incentive, penalty-incentive, and baseline). Behavioral data showed that the incentive conditions modulated task performance, potentially by altering participants’ cognitive control strategy. Neuroimaging data indicated that the reward condition was associated with a sustained increase in a primarily right-lateralized network that included parietal and prefrontal cortex. Additionally, individual differences were observed, such that activation in both reward-related brain regions and frontopolar cortex was linked to the degree of motivation-induced performance enhancement and to motivation-related personality variables. These results suggest that changes in motivational state may modulate performance through sustained activity in cognitive control regions and that the effect of incentives may be affected by the personalities of the participants. 相似文献

Developmental improvements in face identity recognition ability are widely documented, but the source of children’s immaturity in face recognition remains unclear. Differences in the way in which children and adults visually represent faces might underlie immaturities in face recognition. Recent evidence of a face identity aftereffect (FIAE), in which adaptation (exposure) to a particular identity causes a previously neutral face to take on the computationally opposite identity, suggests that adults code faces in an opponent fashion relative to an average face. One previous study showed comparable FIAEs in 8-year-olds and adults but did not demonstrate that adaptation was selective for high-level representations in both groups. Using a developmentally appropriate FIAE task, we investigated whether children show adult-like adaptation for facial identity when adapting and test images differ in size. Both age groups showed an equivalent FIAE, suggesting that qualitative changes in the use of higher level adaptive coding mechanisms do not drive the developmental improvements in face recognition ability, at least from 8 years of age. 相似文献

Although intergroup contact is generally associated with positive intergroup attitudes, little is known about whether individual differences moderate these relations, or how contact might operate among prejudice‐prone individuals. The present investigation explores Person × Contact and Person × Friendship interaction patterns among heterosexual university students. As expected, the positive relations of right‐wing authoritarianism (RWA) and heterosexual identification with prejudice against homosexuals were weakened when participants reported increased contact, more positive contact, direct (personal) friendships, or indirect friendships (i.e., ingroup friends with outgroup friends) with homosexuals. These patterns held after controlling statistically for each person or situation variable. Contact and friendship exerted smaller or negligible effects among low authoritarians or low identifiers. Tests of indirect effects revealed that among high authoritarians or high identifiers, contact and friendship exerted influence on attitudes through group‐level perceptions that homosexuals promote societal values and through increased self–other overlap with gay friends, each otherwise resisted by these individuals. Overall these results suggest that: (a) intergroup contact and intergroup friendship are related but distinct constructs; and (b) past findings underestimate contact effects by collapsing across levels of personal biases.

Brain-derived neurotrophic factor (BDNF) plays a regulatory role in neuronal differentiation and synaptic plasticity and has been linked to glucose regulation and cognition. Associations among plasma BDNF, cognition, and insulin function were explored. Forty-one participants with impaired insulin function (IIF), ranging from insulin resistance to type 2 diabetes mellitus (T2DM), were matched with 41 healthy controls on gender, age, education, and IQ. Participants received complete medical, neurological, psychiatric, and neuropsychological evaluations. IIF individuals had significantly lower plasma BDNF levels than controls, particularly females, and higher BDNF levels were associated with poorer explicit memory in IIF females, suggesting that higher levels within this group may reflect the body’s efforts to respond to damage. After accounting for age, education, and HbA1c, BDNF significantly predicted 13.1–23.5% of the variance in explicit memory in IIF women. These findings suggest that BDNF elevations within diseased groups may not always be a marker of health. 相似文献
