When recalling key definitions from class materials, college students are often overconfident in the quality of their responses. Even with commission errors, they often judge that their response is entirely or partially correct. To further understand this overconfidence, we investigated whether idea-unit judgements would reduce overconfidence (Experiments 1 and 2) and whether students inflated their scores because they believed that they knew answers but just responded incorrectly (Experiment 2). College students studied key-term definitions and later attempted to recall each definition when given the key term (e.g., What is the availability heuristic?). All students judged the quality of their recall, but some were given a full-definition standard to use, whereas other students first judged whether their response included each of the individual ideas within the corresponding correct answer. In Experiment 1, making these idea-unit judgements reduced overconfidence for commission errors. In Experiment 2, some students were given the correct definitions and graded other students’ responses, and some students generated idea units themselves before judging their responses. Students were overconfident even when they graded other students’ responses, and, as important, self-generated idea units for each definition also reduced overconfidence in commission errors. Thus, overconfidence appears to result from difficulties in evaluating the quality of recall responses, and such overconfidence can be reduced by using idea-unit judgements. 相似文献

Abstract The present study sought to identify some of the mechanisms that make safer sex such a difficult topic to talk about. Fifty six dating couples participated in a laboratory study in which the opposite-sex members of two pairs of couples engaged in two discussions of safer sex (or a control topic), each time with a different opposite-sex partner (their own dating partner or an opposite-sex stranger). The results indicated that discussions of safer sex evoke in dating partners a high level of perceived goal-incompatibility, difficulty maintaining one's focus on the topic, and difficulty in reading the other partner's thoughts and feelings. These reactions did not occur in response to the control topic. This initial demonstration study is important with respect to the processes it implicates, but further clarification is needed regarding the specific real-life conditions in which these processes do, and do not, occur. 相似文献

Are depressive symptoms in middle childhood associated with more or less realistic social self-perceptions? At the beginning and end of the school year, children in grades 3 through 5 (n=667) rated how much they liked their classmates, predicted the acceptance ratings they would receive from each of their classmates, and completed self-report measures of perceived acceptance and depressive symptoms. Accuracy of perceived acceptance was indexed by the mean difference between pairs of predicted and received ratings (absolute values). Standardized residual scores created by regressing self-reported perceived acceptance (either predicted ratings or children's responses to a questionnaire measure of perceived peer acceptance) onto peer acceptance ratings formed two measures of bias. Bi-directional associations were found for accuracy of perceived acceptance and depressive symptoms; inaccurate perceptions predicted increases in depressive symptoms and depressive symptoms predicted decreased accuracy. Neither measure of bias predicted changes in depressive symptoms. Depressive symptoms predicted increases in negatively biased perceptions as assessed via questionnaire. 相似文献

Parents' Estimations of Preschoolers' Number Skills Relate to at‐Home Number‐Related Activity Engagement 下载免费PDF全文
According to Hunt's match hypothesis, the accuracy of parents' beliefs about their children's abilities can influence the nature of the early learning experiences they provide. The present study examined the accuracy of parents' beliefs about their preschoolers' number development and relations to parent‐reported frequency of engaging children in number related experiences at home. Parents reported engaging their preschoolers more frequently in conventional numeracy activities, (i.e. counting and identifying numbers) than advanced number‐related activities (e.g. arithmetic) at home, though the frequency of advanced activities increased with the development of children's advanced number skills. Parents were most uncertain about their children's advanced number skills, though they demonstrated an overall tendency to overestimate their children's abilities across number tasks. Increased rates of overestimation and decreased rates of underestimation were associated with increased incidences of advanced activity engagement at home. Thus, results suggest guiding parents to understand their own children's numerical understanding in a wide range of number domains could promote more advanced at‐home number‐related activity engagement.

This study examined the effect of short-term practice on the parameters of a linear model involving mean arm movement time as a function of Fitts’s index of difficulty (ID) variable and a preview-constraint ID variable. Significant (at the 2% level) interactions were found to exist between practice and the two ID variables indicating that the model parameters associated with these variables are both linear functions of practice time. 相似文献

幼儿选择性信任的发展对幼儿社会认知和社会行为的发展有重要的促进作用。本研究探讨当信息提供者的友善特质与所提供信息的准确性相冲突时,幼儿在认知信任问题与人际信任问题上的信任选择特点。以103名3~5岁幼儿为被试,研究结果发现3~4岁幼儿在与认知信任有关问题中做出的选择与随机水平相比无显著差异,只有5岁幼儿表现出了对准确命名但不友善的信息提供者的赞同和询问偏好; 而在人际信任判断中,3~5岁幼儿均选择与具有友善特质的人为友,并将物品交于其保管。研究结果说明不同年龄段的幼儿表现出不同的信任选择倾向,且幼儿能依据不同问题灵活做出信任选择。 相似文献

Repeated recall, as a result of repeated questioning, is typical of situations involving eyewitness evidence. The present study addressed questions of eyewitness performance with reference to repeated questioning in an initial interview, in a format based on actual police procedures. This experiment focused on eyewitness accuracy, eyewitness confidence, and the addition of false details to eyewitness accounts. Ninety‐two adult respondents were asked to recall all the information they could from a single viewing of a scene depicting an assailant aiming a handgun at a victim. This initial question was followed by three additional questions, in which respondents were asked to report any additional details they could recall. On average, respondents provided several times as many correct as false details to the initial question. However, performance deteriorated significantly to the three subsequent questions; on average, across the three subsequent questions, witnesses recalled nearly as much false as accurate information. Witness confidence was positively related to amount of accurate information recalled. However, confidence was also positively related to the number of instances of erroneous recall. These results indicate that reconfigurative dynamics begin to operate, producing confabulated responses in response to questioning demands, as early as the initial interview. This work may also help to clarify the critical relationship between accuracy and confidence in eyewitness reportage, at least within the framework reflected by the present research.

The strategic use of evidence (SUE)—a method of using case information to elicit different verbal responses from guilty and innocent suspects—has been shown to increase cues to deception and lie detection accuracy. This study manipulated the timing of evidence presentation to determine its effect on cues to deception, lie detection accuracy, and confession rates. Liars were less consistent with the evidence, and SUE was associated with higher lie detection accuracy. Results showed no difference between early and late disclosure of evidence on suspects' confession rates, nor on the diagnosticity of the confessions. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献
