Research has shown that the memory characteristics questionnaire (MCQ) can be used to discriminate between ‘memories’ of perceived events and ‘memories’ of imagined events. The present study extended this research by examining the utility of the MCQ in distinguishing impossible memories (i.e., reports of an event a person could not have witnessed). Congruent with previous research, a considerable number of participants in both the pilot study (45%) and the main study (44%) were willing to report that they had seen a non‐existent film of the car crash in which Diana, Princess of Wales was killed. The MCQ ratings of three groups of participants were therefore compared: (1) those who indicated that they had seen the non‐existent film, (2) those who were asked to imagine having seen the film, and (3) a control group who were asked to rate their memory of when they first heard the news of the crash. The MCQ did not serve to distinguish impossible memories, but there were reliable differences on one of the MCQ subscales between those who imagined the film and controls. Furthermore, participants who reported that they had seen the film gave higher scores on the Self Monitoring scale. Implications are discussed. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

This paper explores and reflects upon the body of relevant social science data sources containing insights into gay male socio-sexual
lifestyles. Considerable deficiencies seem to feature in this regard with respect to coverage, consistency, content and usability.
The various reasons for collecting data on gay male lifestyles are considered and thought given as to some particular strengths
and weaknesses. Examples of datasets and surveys are used in this light to potentially inform future developments and a critical
perspective on their usage.

Inoue and Matsuzawa (Curr Biol 17: R1004–R1005, 2007) showed that with an accuracy of approximately 79%, the juvenile chimpanzee, Ayumu, could recall the position and order of
a random subset of five Arabic numerals between one and nine when those numerals were presented for only 210 ms on a computer
touch screen before being masked with white squares. None of nine humans working on the same task approached this level of
accuracy. Inoue and Matsuzawa (2007) claimed this performance difference was evidence of a memorial capacity in young chimpanzees that was superior to that seen
in adult humans. While the between-species performance difference they report is apparent in their data, so too is a large
difference in practice on their task: Ayumu had many sessions of practice on their task before terminal performances were
measured; their human subjects had none. The present report shows that when two humans are given practice in the Inoue and
Matsuzawa (2007) memory task, their accuracy levels match those of Ayumu. 相似文献

Pigeons were exposed to a repeated acquisition procedure in which no delays were imposed and rate of responding was relatively high. They also were exposed to conditions in which delays were arranged between trials within chains or between completed chains, and rates of responding were lower. Number of trials, rate of reinforcement, difficulty of the discrimination, and motivating operations were held constant. Terminal accuracy was highest under the no‐delay condition, in which rate of responding was highest. Effects of trial spacing on retention were mixed and depended on whether delays were imposed between trials within chains or between completed chains. These findings provide basic‐research support for the rapid presentation of trials in direct instruction and for rate building in precision teaching. 相似文献

Using positron emission tomography (PET), we explored the neural correlates of an executive function, dual tasking, in patients with amnestic mild cognitive impairment (aMCI) and in elderly controls. The experiment employed simple auditory and visual tasks that were presented both in isolation and simultaneously to create a task condition requiring enhanced attentional control. Behaviorally, both groups performed well, albeit the patients made more errors on the visual task. The PET analysis focused at prefrontal regions where group differences in task-related activation patterns were expected. During dual task performance, the patients showed attenuated activity in the left inferior frontal region when compared to the controls. This suggests abnormalities in the neural processes underlying attentional control in aMCI. 相似文献

Although current research indicates that psychotherapeutic change both affects and is affected by spiritual concerns, relatively little is known about the degree to which spirituality is used as an intervention in counseling and how it is perceived by clients and mental health professionals. The purpose of this study was to examine the perceptions of clients and professionals regarding the use of spirituality in counseling. The results suggest that more professionals may be using spirituality in counseling than has previously been reported. 相似文献

To examine the effects of event plausibility on people's false beliefs and memories for imagined childhood events, subjects took part in a three‐stage procedure. First, subjects rated how confident they were that they had experienced certain childhood events. They also rated their memories of the events. Second, 1 week later, subjects imagined one high, one moderate and one low plausibility event. Third, 1 week later (and 2 weeks after their initial ratings), subjects rated their confidence and memory a second time. Imagining the events made subjects more confident that they were genuine experiences and gave subjects clearer and more complete memories. Plausibility did not affect subjects' confidence but it did affect their memories. Subjects developed clearer and more complete memories for high, followed by moderate, followed by low plausibility events regardless of whether those events were imagined. We use a nested model of plausibility, belief and memory to discuss our findings. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献
