S. E. Clark, A. Hori, A. Putnam, and T. J. Martin (2000) showed that collaboration on a recognition memory task produced facilitation in recognition of targets but had inconsistent and sometimes negative effects regarding distractors. They accounted for these results within the framework of a dual-process, recall-plus-familiarity model but showed only weak evidence to support it. The present results of 3 experiments present stronger evidence for Clark et al.'s dual-process view and also show why such evidence is difficult to obtain. 相似文献

Disorder-congruent interpretations of ambiguous stimuli characterize several psychological disorders and have been implicated in their maintenance. Models of insomnia have highlighted the importance of cognitive processes, but the possibility that biased interpretations are important has been minimally investigated. Hence, a priming methodology was employed to investigate the presence of an interpretive bias in insomnia. A sample of 78 participants, differing in the presence of a diagnosis of insomnia, severity of sleep disturbance, and sleepiness, was required to read ambiguous sentences and make a lexical decision about target words that followed. Sleepiness at the time of the experiment was associated with the likelihood with which participants made insomnia and threat consistent interpretations of ambiguous sentences. The results suggest that there is a general bias towards threatening interpretations when individuals are sleepy and suggests that cognitive accounts of insomnia require revision to include a role for interpretative bias when people are sleepy. Future research is required to investigate whether this interpretive bias plays a causal role in the maintenance of insomnia. 相似文献

Is the Brain a Quantum Computer? 总被引:1,自引:0,他引:1
We argue that computation via quantum mechanical processes is irrelevant to explaining how brains produce thought, contrary to the ongoing speculations of many theorists. First, quantum effects do not have the temporal properties required for neural information processing. Second, there are substantial physical obstacles to any organic instantiation of quantum computation. Third, there is no psychological evidence that such mental phenomena as consciousness and mathematical thinking require explanation via quantum theory. We conclude that understanding brain function is unlikely to require quantum computation or similar mechanisms. 相似文献

Using data from the Health and Retirement Study, I examine the relationship between adult mortality and religious affiliation. I test whether mortality differences associated with religious affiliation can be attributed to differences in socioeconomic status (years of education and household wealth), attendance at religious services, or health behaviors, particularly cigarette and alcohol consumption. A baseline report of attendance at religious services is used to avoid confounding effects of deteriorating health. Socioeconomic status explains some but not all of the mortality difference. While Catholics, Evangelical Protestants, and Black Protestants benefit from favorable attendance patterns, attendance (or lack of) at services explains much of the higher mortality of those with no religious preference. Health behaviors do not mediate the relationship between mortality and religion, except among Evangelical Protestants. Not only does religion matter, but studies examining the effect of "religiosity" need to consider differences by religious affiliation. 相似文献

We examined the effect of three variables (test list structure, report option, and framing) on retrospective bias in global
evaluations of test performance (postdictions). Participants answered general knowledge questions and estimated correctness
of their performance after each block. The ordering of the questions within a block affected bias: Participants believed they
had answered more questions correctly when questions were sorted from the easiest to the hardest than when the same questions
were randomized or sorted from the hardest to the easiest. This bias was obtained on global postdictions but was not apparent
on item-by-item ratings, pointing to a memory-based phenomenon. In addition, forcing participants to produce a response to
every question increased performance without affecting evaluations. Finally, framing the evaluation question in terms of the
number of questions answered incorrectly (rather than the number correctly answered) did not affect how positively participants
evaluated their performance, but did render postdictions less accurate. Our results provide evidence that students’ evaluations
of performance after a test are prone to retrospective memory biases. 相似文献

Previous accounts of the memory distortion known as the change-of-standard effect hypothesize that participants form a relative impression of a target at encoding and later use that impression with the average
of all items to recall the target (Higgins & Lurie, 1983). In three experiments, we investigated the standard and the integration
of the standard with the relative impression. Experiments 1 and 2 show that participants’ subjective average at recall is
distorted toward recent stimuli: It is computed when required and is therefore affected by the items’ accessibility at that
time. Furthermore, the impression’s influence on recall is relatively small when the context changes between encoding and
decoding. Experiment 3 shows that this change in the impression’s influence occurs only when the participant integrates information
across sessions, suggesting that such tasks make participants aware of the changed context and cause them to adjust the use
of their impression in recalling the target. 相似文献

We propose that we encode and store information as a function of the particular ways we have used similar information in the past. More specifically, we contend that the experience of retrieval can serve as a powerful cue to the most effective ways to encode similar information in comparable future learning episodes. To explore these ideas, we did two studies in which all participants went through study–test cycles of single category lists while we manipulated the nature of the recognition tests. The recognition tests either included only same-category lures or only different-category lures. The experience of repeated testing leads participants to avoid conceptual-based strategies but only when conceptual knowledge was poorly diagnostic for recognition (i.e., in the same-category lures condition). In a second study with a similar manipulation, we showed that repeated testing with lures from the same category as study items improved performance in a final recall surprise test compared to conditions in which different-category lures were used. Such a difference is akin to the one obtained when encoding instructions focus on distinctive item features compared to cases in which the focus is on relational processing. We suggest that testing requirements lead to adaptive changes at encoding. 相似文献

Children's concepts of various social roles were examined in a task that required the child to indicate the similarity of two occupants of common social roles. Each occupant in the pair was described differently in terms of behaviors appropriate for a particular role. Children in the first, third, and sixth grades were studied. Findings indicated that children in the youngest group held role concepts based primarily on concrete actions, while role concepts of the older two groups were based on more abstract, general role functions. In addition, there is some suggestion that the level of role conceptualization is related to the relevance of the particular role. 相似文献

Although numerous studies have attempted to understand the causes of various forms of police misconduct, there is still no clear theoretical explanation of police misbehavior. Akers’ social learning theory posits that peer associations, attitudes, reinforcement, and modeling are predictors of delinquency and crime in general. With this article, we seek to determine if the theory can account for police deviance. Data from a random sample of Philadelphia police officers are used to examine how officer attitudes and perceptions of peer behavior are related to citizen complaints of police misconduct. Findings suggest that social learning theory provides a useful explanation of police misconduct. 相似文献

The trunk muscle transversus abdominis (TrA) is thought to be controlled independently of the global trunk muscles. Methodological issues in the 1990s research such as unilateral electromyography and a limited range of arm movements justify a re-examination of this theory. The hypothesis tested is that TrA bilateral co-contraction is a typical muscle synergy during arm movement. The activity of 6 pairs of trunk and lower limb muscles was recorded using bilateral electromyography during anticipatory postural adjustments (APAs) associated with the arm movements. The integrated APA electromyographical signals were analyzed for muscle synergy using Principle Component Analysis. TrA does not typically bilaterally co-contract during arm movements (1 out of 6 participants did). APA muscle activity of all muscles during asymmetrical arm movements typically reflected a direction specific diagonal pattern incorporating a twisting motion to transfer energy from the ground up. This finding is not consistent with the hypothesis that TrA plays a unique role providing bilateral, feedforward, multidirectional stiffening of the spine. This has significant implications to the theories underlying the role of TrA in back pain and in the training of isolated bilateral co-contraction of TrA in the prophylaxis of back pain. 相似文献
