This study investigated determinants of success in a ‘synthetic work’ task designed to reflect the requirement for multitasking that is common to many occupations. Participants were administered tests of working memory capacity (WMC) and processing speed (PS), and they reported experience with videogames, a type of activity presumed to involve multitasking. Results revealed that WMC was a strong predictor of multitasking in a ‘non‐emergency’ condition when the pace of the tasks was relatively slow, whereas PS was a weaker predictor. Additionally, there was evidence for the incremental validity of videogame experience (VGE), consistent with the possibility that multitasking is supported by a general, trainable skill. Finally, individual differences in strategy use accounted for a large proportion of the variance in multitasking, above and beyond other predictor variables, and WMC predicted use of an effective strategy.

Three studies examined the effect on compliance when a requester raises the price of the request. Participants in Experiment 1 were told that they would receive a free coffee mug for donating money to a fundraiser but were interrupted before they could respond and were told that the fundraisers were out of mugs. These participants were less likely to donate money than a group told nothing about the mugs. Experiments 2 and 3 compared this interruption procedure with the lowball procedure, which also uses a small‐to‐large price progression. The results from these two studies indicate that allowing people to respond to the initial price is critical for producing the lowball effect. Without a statement of public commitment, the small‐to‐large price progression led to a decrease rather than an increase in compliance relative to a control group. 相似文献

There appears to be a relative absence of studies that have examined the prevalence of cognitively intact individuals who reside in extended care facilities. Prevalence data were collected on 296 persons who resided in 3 extended care nursing facilities in Central Virginia. Cognitive intactness was evaluated via the Minimum Data Set Cognitive Performance Scale (CPS) and an author-generated survey (i.e., Cognitively Intact Survey [CI Survey]) of select nursing staff members at each facility. The Mini-Mental State Examination (MMSE) was utilized to examine the accuracy of the two measures in identifying cognitive intactness. Findings indicated that prevalence rates of cognitively intact residents varied as a function of the measures utilized to assess intactness. Specifically, a significantly greater proportion of the total sample of residents was judged to be cognitively intact via the CI Survey (34.12%) as compared to the CPS (26.01%). The level of interjudge agreement between the two measures was found to be moderately high (K = 0.68). When the MMSE was employed to verify individuals' levels of intactness, the percentages of residents predicted to actually be cognitively intact were somewhat lower for each measure. Specifically, based on the data obtained via the CI Survey, 22.75% of the total sample were predicted to actually be cognitively intact, whereas 17.85% of the sample were predicted to be intact based on the CPS results. Findings are discussed in light of factors that may have contributed to the differential prevalence rates of cognitively intact individuals obtained across the measures utilized in this study. Concerns regarding the utilization of the MMSE as a criterion measure of cognitive intactness in persons residing in extended care nursing facilities are provided, along with data on the living environments/roommate statuses of those residents judged to be intact via the CI Survey. Implications for the design of future extended care nursing units, as well as future research, are also included. 相似文献

We followed up over 90% of 57 motor vehicle accident survivors, who completed a controlled comparison of cognitive behavioral therapy (CBT) to supportive psychotherapy (SUPPORT). One-year results showed a continued significant advantage on categorical diagnosis (PTSD or not) and structured interview measures (CAPS) for CBT over SUPPORT. Other measures generally showed the same results. At two years, we were able to follow-up only 75% of one-year completers. Although there continued to be arithmetic differences favoring CBT over SUPPORT, with these attenuated samples only differences on PTSD Checklist and Impact of Event Scale scores and in overall categorical diagnoses were significant. There was very modest improvement from end of treatment to the two-year follow-up. 相似文献

Locus of control as a moderator of the relationship between medication barriers (e.g., side-effects, forgetting to take medication, and keeping track of pills) and anti-hypertensive medication adherence was examined. Baseline data were obtained from 588 hypertensive veterans. In general, fewer medication barriers, higher internal locus of control and lower external locus of control was associated with better hypertensive medication adherence. Furthermore, internal locus of control served as a moderator (beta = -.74, p < .01) for the relationship between medication barriers and medication adherence; effect size was large. Decomposition of the interaction revealed that the relationship between medication barriers and medication adherence was strongest when internal control was high (b = -.24, p < .01). Higher internal locus of control was beneficial when barriers to medication adherence are low, but at high perceived barriers, locus of control plays less of a role in medication adherence. Future efforts to improve medication adherence should consider the patient's perceived level of medication barriers in conjunction with their locus of control. 相似文献

The technology of brief experimental analysis is just beginning to be used for identification of effective treatments for individual students who experience difficulty with oral reading fluency. In this study, the effect of a reading fluency treatment package was examined on easy and hard passages, and generalization was assessed on passages with high content overlap. The results suggest that the treatment package increased reading fluency for all 3 students. Effects were moderated by difficulty level for all 3 students. Results are discussed in terms of future refinements to the procedures, validation of the methods, and potential applications in clinical and school settings. 相似文献

Two prospective studies examined the self-regulatory role of anticipated negative self-conscious emotions (ANSCE) in the theory of planned behavior. In Study 1, 147 undergraduates reported condom attitudes, perceived norms, self-efficacy, ANSCE (shame and guilt) should they not use condoms, and intentions to use condoms during the coming 6 weeks. At a 6-week follow-up, ANSCE predicted condom use intentions and behavior and partially mediated the effect of attitudes and norms on both. Study 2 experimentally tested the social nature of self-consciousness in ANSCE; 61 female undergraduates read a scenario priming the private-self or social-self or were assigned to a no-scenario control. They reported condom attitudes, perceived control, ANSCE, condom use intentions, and a 6-week follow-up. ANSCE again predicted condom use intentions. A test of moderated mediation indicated that ANSCE influenced condom intentions more in the social-self condition than in the control condition. Implications of these findings are discussed. 相似文献

This article examines the intellectual and institutional factors that contributed to the collaboration of neuropsychiatrist Warren McCulloch and mathematician Walter Pitts on the logic of neural networks, which culminated in their 1943 publication, "A Logical Calculus of the Ideas Immanent in Nervous Activity." Historians and scientists alike often refer to the McCulloch-Pitts paper as a landmark event in the history of cybernetics, and fundamental to the development of cognitive science and artificial intelligence. This article seeks to bring some historical context to the McCulloch-Pitts collaboration itself, namely, their intellectual and scientific orientations and backgrounds, the key concepts that contributed to their paper, and the institutional context in which their collaboration was made. Although they were almost a generation apart and had dissimilar scientific backgrounds, McCulloch and Pitts had similar intellectual concerns, simultaneously motivated by issues in philosophy, neurology, and mathematics. This article demonstrates how these issues converged and found resonance in their model of neural networks. By examining the intellectual backgrounds of McCulloch and Pitts as individuals, it will be shown that besides being an important event in the history of cybernetics proper, the McCulloch-Pitts collaboration was an important result of early twentieth-century efforts to apply mathematics to neurological phenomena. 相似文献
