Disjunctive inferences are difficult. According to the theory of mental models, it is because of the alternative possibilities to which disjunctions refer. Three experiments corroborated further predictions of the mental model theory. Participants judged that disjunctions, such as Either this year is a leap year or it is a common year are true. Given a disjunction such as Either A or B, they tended to evaluate the four cases in its ‘partition’: A and B, A and not‐B, not‐A and B, not‐A and not‐B, as ‘possible’ or ‘impossible’ in ways that bore out the difference between inclusive disjunctions (‘or both’) and exclusive disjunctions (‘but not both’). Knowledge usually concerns what is true, and so when participants judge that a disjunction is false, or contingent, and evaluate the cases in its partition, they depend on inferences that yield predictable errors. They tended to judge that disjunctions, such as follows: Either the food is cold or else it is tepid, but not both, are true, though in fact they could be false. They tended to infer ‘mirror‐image’ evaluations that yield the same possibilities for false disjunctions as those for true disjunctions. The article considers the implications of these results for alternative theories based on classical logic or on the probability calculus.  相似文献

ABSTRACT

Individuals tend to rate themselves more positively than strangers or acquaintances—a self-enhancement effect. But such self-enhancement is potentially detrimental to one's intimate relationships. We hypothesized that higher relationship quality would predict (1) partner-enhancement (i.e., rating the partner more positively than the self) and (2) higher feelings of being understood and validated (FUV). In addition, (3) partner-enhancement would add to relationship quality's prediction of FUV. These hypotheses were tested among cross-sex friendships (N = 92) and dating relationships (N = 90) in University students and in a married, non-University sample (N = 94). All hypotheses were supported in romantic relationships. For cross-sex friendships, regardless of relationship quality, individuals partner-enhanced on the negative traits but neither self- nor partner-enhanced on the positive traits. Finally, relationship quality predicted partner-perceptions more strongly than self-perceptions.  相似文献

The authors examined the relationships of cognitive (i.e., memorization and elaboration) and metacognitive learning strategies (i.e., control strategies) to mathematics achievement among 15-year-old students in 4 high-performing East Asian education systems: Shanghai-China, Hong Kong-China, Korea, and Singapore. In all 4 East Asian education systems, memorization strategies were negatively associated with mathematics achievement, whereas control strategies were positively associated with mathematics achievement. However, the association between elaboration strategies and mathematics achievement was a mixed bag. In Shanghai-China and Korea, elaboration strategies were not associated with mathematics achievement. In Hong Kong-China and Singapore, on the other hand, elaboration strategies were negatively associated with mathematics achievement. Implications of these findings are briefly discussed.  相似文献

图形推理任务中儿童策略获得的发展机制   总被引:3,自引:0,他引:3

运用微观发生学设计对30名6岁儿童在矩阵填充任务中策略获得的发展机制进行了研究。结果发现:(1)从策略获得点前的错误类型分析,这个阶段主要是元认知机制起决定作用,图形推理的策略获得是一个渐进过程;(2)从反应时的变化趋势分析,元认知机制仍起决定作用,而在策略获得后期,联结机制代替元认知机制起决定性作用;(3)从自我解释中提到的维度分析,也表明元认知机制起着决定性作用,但联结机制在某些题目维度上已经逐渐“竞争”超过了元认知机制。  相似文献

Is forgotten information deemed less important than remembered information? The present study examined potential biases regarding the importance of information that was initially forgotten. In Experiment 1 participants studied words paired with varying point values that denoted their importance and were encouraged to recall higher value words. Participants recalled more high-value words on an initial test. However, on a later cued recall test for the values, initially forgotten words were rated as less valuable than remembered words. Experiment 2 used a similar procedure with the exception that participants rated the importance of traits when evaluating a significant other (e.g., honest, intelligent). Participants were more likely to recall highly valued traits but regarded forgotten traits as less valuable than remembered traits. These results suggest that a forgetting bias exists: If information is initially forgotten, it is later deemed as less important.  相似文献

以217名高中生为被试,采用计算机监控的活动操作法,探讨课堂成就目标定向、任务难度对不同学业水平学生元认知监控策略运用的影响。结果表明:(1)课堂掌握目标定向下均比在课堂成绩目标定向下更多地运用元认知监控策略;(2)高学业学生在较难任务上比较易任务上更多地运用元认知监控策略;低学业学生,在课堂掌握目标定向下.在较难任务上比较易任务上更多地使用元认知监控策略;在课堂成绩目标定向下,与课堂掌握目标定向情形相反;(3)临场动机中的自我效能感、目标方向、努力程度在课堂成就目标定向、任务难度对元认知监控策略的影响中具有中介作用。  相似文献

The effect of the horizontal-vertical illusion on the visual and visuomotor systems was investigated. Participants (N = 8) viewed horizontal and vertical lines in an inverted-T stimulus and judged whether the two line segments were the same or different lengths. Participants also reached out and grasped either the vertical or the horizontal line segment of the stimulus. Perceptually, participants succumbed to the illusion; that is, they judged Ts of equal horizontal and vertical line lengths to be different and Ts of unequal line lengths to be the same. When reaching toward the same stimuli, however, the size of their grip aperture was scaled appropriately for the various line lengths. Thus, whereas the perceptual system succumbed to the illusion, the visuomotor system did not. Those results support a model proposed by M. A. Goodale and A. D. Milner (1992), who posited separate cortical pathways for visual perception and visually guided action.  相似文献

Individuals with autism show various signs of heightened abilities in visuo‐spatial functioning. First, it is long‐established that they excel on embedded figures and block design tests relative to comparison participants. Second, some evidence suggests that processing global features is affected by inappropriate processing of the constituent elements of a stimulus. Third, they are more accurate than comparison participants in judging the shape of a slanted circle in a context in which ambient visual cues are eliminated. This suggests that their perception of the shape is less influenced by prior knowledge. Fourth, they are fast at searching for feature and conjunctive targets in a visual array. Contrary to earlier reports, however, they are susceptible to visual illusions. Also, they do show evidence of utilising prior knowledge when pairing a colour with an atypically coloured target. Accordingly, we conclude that there is something distinctive about autistic visuo‐spatial functioning, but not necessarily in ways that are predicted by the ‘weak central coherence’ hypothesis.

气候变化已经成为全球面临的最紧迫问题之一。近期研究发现,个体对于气候变化风险的元认知和其亲环境行为之间关系密切。对元认知知识、元认知来源、元认知确定性及元认知重要性四个维度相关研究的分析表明,公众元认知知识与实际知识的偏离、以分析系统为主导的风险认知来源、对气候变化后果确定性的低估以及对气候变化重要性的忽视都会抑制环境友好行为的发生,并指出了气候变化风险元认知研究的未来趋势。  相似文献
