Seventy-two undergraduates viewed a videotape of a bank robbery that culminated in the shooting of a young boy. Several days later, participants were interviewed about their recollection of events in the film through baseline oral and written narrative accounts followed by random assignment to a hypnosis (HYP) condition, the cognitive interview (CI), or a motivated, repeated recall (MRR) control interview. Participants also completed a forced interrogatory recall test, which indexed potential report criterion differences between the interview conditions. In terms of information provided for the first time during treatment interviews, HYP led to greater productivity than the CI or the MRR interview, which did not differ significantly from each other. Evidence that these differences in recall resulted primarily from report criterion differences rather than differences in accessible memory was obtained from the forced interrogatory recall test. In this test, no differences were observed between the three interview conditions. Finally, the data revealed that participants' hypnotic ability was associated with the recall of erroneous and confabulatory material for those tested in the HYP and CI conditions but not those in the MRR condition. This suggests that some CI mnemonics may invoke hypnotic-like processes in hypnotizable people. 相似文献

The ability to efficiently search the visual environment is a critical function of the visual system, and recent research has shown that experience playing action video games can influence visual selective attention. The present research examined the similarities and differences between video game players (VGPs) and non-video game players (NVGPs) in terms of the ability to inhibit attention from returning to previously attended locations, and the efficiency of visual search in easy and more demanding search environments. Both groups were equally good at inhibiting the return of attention to previously cued locations, although VGPs displayed overall faster reaction times to detect targets. VGPs also showed overall faster response time for easy and difficult visual search tasks compared to NVGPs, largely attributed to faster stimulus-response mapping. The findings suggest that relative to NVGPs, VGPs rely on similar types of visual processing strategies but possess faster stimulus-response mappings in visual attention tasks. 相似文献

Working memory (WM) is the set of mental processes holding limited information in a temporarily accessible state in service of cognition. We provide a theoretical framework to understand the relation between WM and aptitude measures. The WM measures that have yielded high correlations with aptitudes include separate storage-and-processing task components, on the assumption that WM involves both storage and processing. We argue that the critical aspect of successful WM measures is that rehearsal and grouping processes are prevented, allowing a clearer estimate of how many separate chunks of information the focus of attention circumscribes at once. Storage-and-processing tasks correlate with aptitudes, according to this view, largely because the processing task prevents rehearsal and grouping of items to be recalled. In a developmental study, we document that several scope-of-attention measures that do not include a separate processing component, but nevertheless prevent efficient rehearsal or grouping, also correlate well with aptitudes and with storage-and-processing measures. So does digit span in children too young to rehearse. 相似文献

Parent reports and laboratory assessments of child temperament traits were compared in terms of their associations with 2 indices of risk for future maladjustment: maternal history of depression and disruptive school behavior. A community sample of 99 pre-school-aged children completed a standardized battery of laboratory tasks designed to tap positive emotionality (PE) and anger. Parent reports of child temperament were collected, and maternal history of depression was assessed using structured clinical interviews. An average of 18.5 months after the initial laboratory assessment, teacher reports of disruptive school behavior were collected. Structural equation models were used to test the association between the 2 assessment approaches of child temperament and maternal history of depression and disruptive school behavior. Laboratory measures and parent reports of anger were equally good at predicting disruptive school behavior, while laboratory measures of PE showed stronger associations with maternal history of depression than parent report. 相似文献

Although optimism, social support, religiousness, and spirituality are important predictors of adjustment, rarely have studies examined these variables simultaneously. This study investigated whether optimism and social support mediated the relationship between religiousness and adjustment (distress and life satisfaction) and between spirituality and adjustment. Findings indicate that the relationship between intrinsic religiousness and life satisfaction and between prayer fulfillment and life satisfaction was mediated by optimism and social support. Furthermore, the relationship between religiousness and adjustment varied depending on how religiousness was operationalized and whether positive versus negative adjustment indicators were used. That is, intrinsic religiousness and prayer fulfillment were associated with greater life satisfaction, but extrinsic religiousness was not associated with life satisfaction. These findings were significant even after accounting for covariates (age, gender, ethnicity, social desirability). Results suggest religiousness and spirituality are related but distinct constructs and are associated with adjustment through factors such as social support and optimism. 相似文献

A study of American Indian youths illustrates competing pressures between research and ethics. A stakeholder-researcher team developed three plans to protect participants. The first allowed participants to skip potentially upsetting interview sections. The second called for participants to skip potentially upsetting interview sections. The second called for participants flagged for abuse or suicidality to receive referrals, emergency 24-hr clinical backup, or both. The third, based on the community's desire to promote service access, included giving participants a list of service resources. Interviewers gave referrals to participants flagged as having mild problems, and reported participants with serious problems to supervisors for clinical backup. Participants seldom chose to skip sections, so data integrity was not compromised. However, participants did have more problems than expected (e.g., 1 in 3 had thought about suicide, 1 in 5 had attempted suicide, and 1 in 4 reported abuse), so service agencies were not equipped to respond. Researchers must accept the competing pressures and find ethically appropriate compromises that will not undermine research integrity. 相似文献

Although research supports the efficacy of exposure therapy for PTSD, some evidence suggests that exposure is under-utilized in general clinical practice. The purpose of this study was to assess licensed psychologists' use of imaginal exposure for PTSD and to investigate perceived barriers to its implementation. A total of 852 psychologists from three states were randomly selected and surveyed. An additional 50 members of a trauma special interest group of a national behavior therapy organization were also surveyed. The main survey results indicate that a large majority of licensed doctoral level psychologists do not report use of exposure therapy to treat patients with PTSD. Although approximately half of the main study sample reported that they were at least somewhat familiar with exposure for PTSD, only a small minority used it to treat PTSD in their clinical practice. Even among psychologists with strong interest and training in behavioral treatment for PTSD, exposure therapy is not completely accepted or widely used. Clinicians also appear to perceive a significant number of barriers to implementing exposure. 相似文献

Previous research has demonstrated that rats will increase their rates of lever pressing for sucrose rewards in the first
half of an experimental session when food pellets, rather than the same sucrose, continually serve as the reward in the second
half of the session. This effect has been coined induction, and the present study investigated whether it could be altered
by altering "motivational" variables. Experiment 1 manipulated subjects' motivation by altering, across conditions, their
level of food deprivation. Predictably, the size of induction varied directly with level of deprivation. Experiments 2 and
3 manipulated subjects' motivation by feeding them food pellets and sucrose, respectively, prior to their responding in the
experimental session. These pre-session feedings decreased the size of the observed induction in both experiments. The results
from the present study indicate that the size of induction is correlated with subjects' motivation to respond for the available
reinforcers. They are also consistent with the idea that operant processes underlie the effect. The notion that induction
might encompass the concept of "anticipation" is also discussed.
