The purpose of this study was to examine the significance of Brown and McNeill’s (1966) findings regarding the “tip of the tongue” (TOT) phenomenon, A modified version of their procedure was used with 56 Ss. Although their findings that Ss in a TOT state can detect parts and properties of the missing word were generally replicated, a division of the TOT state into a variety of substates showed correct detection rate to vary greatly, depending on the substate involved. In addition, correct detection of partial information was demonstrated even when S declared he had no knowledge of the selected word (don’t know). It was suggested that a distinction be made between information detection based on knowledge of the characteristics common to the class of items of which the target is a member (“class detection”) and detection based on knowledge of characteristics specific to the target in question (“differential detection”). Both class and differential detection were found to obtain in TOT states as well as in the don’t know state. Some theoretical and methodological implications were suggested 相似文献

Subjects were instructed to learn a ‘crime’ profile consisting of numerical information, such as the number of the house where the crime was committed, the age of the victim, etc. They were then told not to reveal the information during an interrogation that followed. All the Ss underwent an interrogation in which they were asked to guess the ‘crime’ profile. It was found that it was possible to detect efficiently involvement with the suppressed profile through the use of correlations between the guessed profiles and the ‘crime’ profile as a decision dimension. 相似文献

All subjects earned tokens for correct size judgments and observed a model who had previously earned tokens at the same task donate some of her earnings. Children were subsequently given an opportunity to donate some of their tokens to children at another school. The opportunity to give occurred in presence (surveillance) or absence of the experimenter and after being presented with either directive (you must give) or permissive (you can give if you want to) instructions. Directive instructions and surveillance both produced greater initial giving for all children. In a second session with no modeling, no surveillance, and no further instructions, earlier directive instructions also produced greater persistence of giving for all children. Permissive instructions produced greater reductions in giving over time for boys than for girls. The present findings suggest that directive instructions produce greater initial giving and that donating persists better under these more explicit conditions. 相似文献

Although research has established that people can accurately judge how well they have learned categories, no research has examined whether people use their category-learning judgments (CLJs) to regulate their restudy of natural categories. Thus, in five experiments we investigated the relationship between people’s CLJs and selections of categories for restudy. Participants first attempted to learn natural categories (bird families; e.g., finches, grosbeaks, and warblers) so that they could categorize new exemplars on a final test. After this initial study phase, participants made a CLJ for each category and then selected a subset of the categories for restudy. Across experiments, we also manipulated several variables (e.g., selecting either three or nine categories, or obtaining 30% vs. 80% performance on the final test) that were expected to influence restudy selections. However, the manipulations typically had minimal impact. More important, in all experiments we found an unexpected outcome: Some participants tended to select the categories they judged to be most well learned for restudy, and others tended to select those judged to be least well learned. We discovered these qualitative differences in the use of CLJs to make restudy selections by using post-hoc analyses in Experiments 1a and 1b, and hence we sought to (a) replicate them in Experiments 2, 3, and 4 and (b) provide preliminary evidence regarding factors that can (vs. cannot) account for them. Most important, evidence across all of the experiments supported the conclusion that people do use their CLJs to select categories for restudy. 相似文献

Previous systematic reviews and meta-analyses have identified cognitive deficits in adults with obstructive sleep apnoea (OSA). However, quantitative analysis of the association between OSA and neuropsychological performance has not been conducted specifically in older adults, for whom there is a greater risk of cognitive decline. We searched Medline, Embase and PsycINFO through August 2016 for studies describing associations between OSA and neuropsychological outcomes in people aged>50 years. Meta-analyses were performed on these studies for overall cognition and within cognitive domains. Subgroup analyses were performed taking into account risk of bias and moderating differences in study design. 13 studies met eligibility criteria for analysis. A small negative association was found between OSA and all neuropsychological outcomes combined, g=0.18(95% CI 0.04–0.32), and in memory and processing speed domains. Small case-control studies from sleep clinic populations observed the greatest associations, while larger cohort studies from community samples illustrated no association. Analysis accounting for publication bias resulted in a null overall association, g=0.02 (95%CI -0.12 to 0.16). Associations between OSA and cognition in later life are highly variable and the findings differ based on the type and setting of study. It appears some older adults may be at risk of cognitive impairments attributable to OSA; however, the risk of bias renders the evidence inconclusive. High quality research is warranted in clinically diagnosed OSA patients as well as those already experiencing neuropsychological impairment and who may be regarded at higher risk of further cognitive decline. 相似文献

Jokes are sometimes morally objectionable, and sometimes they are not. What’s the relationship between a joke’s being morally objectionable and its being funny? Philosophers’ answers to this question run the gamut. In this paper I present a new argument for the view that the negative moral value of a joke can affect its comedic value both positively and negatively. 相似文献
