Miller (1956) identified his famous limit of 7 ± 2 items based in part on absolute identification—the ability to identify stimuli that differ on a single physical dimension, such as lines of different length. An important aspect of this limit is its independence from perceptual effects and its application across all stimulus types. Recent research, however, has identified several exceptions. We investigate an explanation for these results that reconciles them with Miller’s work. We find support for the hypothesis that the exceptional stimulus types have more complex psychological representations, which can therefore support better identification. Our investigation uses data sets with thousands of observations for each participant, which allows the application of a new technique for identifying psychological representations: the structural forms algorithm of Kemp and Tenenbaum (2008) . This algorithm supports inferences not possible with previous techniques, such as multidimensional scaling. 相似文献

This study investigated whether young and older adults vary in their beliefs about the impact of various mitigating factors on age-related memory decline. Eighty young (ages 18-23) and 80 older (ages 60-82) participants reported their beliefs about their own memory abilities and the strategies that they use in their everyday lives to attempt to control their memory. Participants also reported their beliefs about memory change with age for hypothetical target individuals who were described as using (or not using) various means to mitigate memory decline. There were no age differences in personal beliefs about control over current or future memory ability. However, the two age groups differed in the types of strategies they used in their everyday life to control their memory. Young adults were more likely to use internal memory strategies, whereas older adults were more likely to focus on cognitive exercise and maintaining physical health as ways to optimize their memory ability. There were no age differences in rated memory change across the life span in hypothetical individuals. Both young and older adults perceived strategies related to improving physical and cognitive health as effective means of mitigating memory loss with age, whereas internal memory strategies were perceived as less effective means for controlling age-related memory decline. 相似文献

Misattributions people make about their own reaction to ambiguous stimuli can be used to measure personality self‐concepts implicitly. On the basis of a semantic misattribution priming paradigm [semantic misattribution procedure (SMP)], we assessed the implicit personality self‐concept related to three dimensions included in the Big‐Five model: conscientiousness, neuroticism, and extraversion. Across three studies (N1 = 98, N2 = 140, and N3 = 135), the SMP was robustly related, in the expected direction, to individual differences in self‐reported personality questionnaires and managed to predict both self‐reported and objectively measured behaviours. The main advantage of SMP over classical explicit measures of personality is its higher resistance to social desirability tendencies, although its psychometric properties are somewhat lower than those pertaining to explicit measures of personality. Finally, comparisons of our results with studies that used other implicit measures of personality self‐concept indicate that the SMP has higher criterion validity.

Self-efficacy is a key construct underlying healthy functioning and emotional well-being. Perceptions of uncontrollability, unpredictability, and low self-efficacy are consistently associated with negative mental health outcomes, such as post-traumatic stress disorder (PTSD). To test the causal relation between perceived coping self-efficacy and stress responses we employed a trauma film paradigm in which college students (N=33) viewed a graphic film of the aftermath of a motor vehicle accident following a high (HSE) or low self-efficacy (LSE) induction. Participants were tested for intrusions, distress, and memory recall for the film over the following 24 hours. LSE participants recalled more central details than HSE participants. Further, HSE participants reported fewer negative intrusions immediately following the film and at 24 hours. These findings suggest that strategies that increase perceived coping self-efficacy may reduce intrusive recollections of an aversive event, and also reduce the attentional bias associated with remembering aversive stimuli. 相似文献

Current models of autobiographical memory suggest that self-identity guides autobiographical memory retrieval. Further, the capacity to recall the past and imagine one's self in the future (mental time travel) can influence social problem solving. We examined whether manipulating self-identity, through an induction task in which students were led to believe they possessed high or low self-efficacy, impacted episodic specificity and content of retrieved and imagined events, as well as social problem solving. Compared to individuals in the low self efficacy group, individuals in the high self efficacy group generated past and future events with greater (a) specificity, (b) positive words, and (c) self-efficacious statements, and also performed better on social problem solving indices. A lack of episodic detail for future events predicted poorer performance on social problem solving tasks. Strategies that increase perceived self-efficacy may help individuals to selectively construct a past and future that aids in negotiating social problems. 相似文献

Nadler (this issue), in his commentary of our article, “Addressing Relapse in Cognitive Behavioral Therapy for Panic Disorder: Methods for Optimizing Long-Term Treatment Outcomes” (Arch & Craske, 2011), argues that we misrepresent the role of panic attacks within learning theory and overlook cognitive treatment targets. He presents several case studies that he argues demonstrate how to target fears regarding the consequences of panic itself. We appreciate his raising these issues and creating the opportunity for discussion. We take issue, however, with two aspects of his commentary. First, his case studies beautifully illustrate a central point we make in our article regarding the importance of violating patient expectancies, and as such, exemplify our recommendations rather than illustrate what we may have overlooked. Second, Nadler's argument that we misidentify the role of panic attacks contradicts itself in ways that reveal his misunderstanding of the complexity of panic attacks from the perspective of learning theory (e.g., Bouton, Mineka, & Barlow, 2001), and disregard an important point we make in our article. 相似文献

The purpose of the current study is to create a comprehensive composite measure of parental influence based on previously developed measures to clarify the underlying dimensions of parental influence and to determine the degree to which parental influence relates to body image and dysfunctional weight concerns. Previously published literature was reviewed for measures of parental influence, and items from 22 measures were condensed and combined into a single questionnaire, which was completed by 367 female undergraduate psychology students. Two dimensions emerged from a principle components analysis: Direct Influence, which includes weight and eating related comments, and Modeling, which includes parental modeling of dieting and related behavior. Direct Influence and Modeling were significantly related to eating disturbance, such as drive for thinness and bulimic symptomatology. Overall, the results integrate the previous literature and clarify the underlying dimensions of parental influence. Further, this study provides directions for future research related to the development and maintenance of body image and eating disturbance. 相似文献

Conventional wisdom suggests that variations in vertical picture angle cause the subject to appear more powerful when depicted from below and less powerful when depicted from above. However, do the media actually use such associations to represent individual differences in power? We argue that the diverse perspectives of evolutionary, social learning, and embodiment theories all suggest that the association between verticality and power is relatively automatic and should, therefore, be visible in the portrayal of powerful and powerless individuals in the media. Four archival studies (with six samples) provide empirical evidence for this hypothesis and indicate that a salience power context reinforces this effect. In addition, two experimental studies confirm these effects for individuals producing media content. We discuss potential implications of this effect. 相似文献

A method for eliciting extended explanations was used to evaluate predictions from the “theory-theory” account of developing psychological reasoning. Children were repeatedly asked to explain the actions or emotions of story characters with false beliefs. Questioning elicited false belief attributions in half of 3-year-olds (Study 1, N = 16, age M = 3;6) and most 4-year-olds who failed belief prediction tasks (Study 2, N = 30, M = 4;5). In Study 3, 30 prediction failers (M = 5;1) gave significantly more false belief explanations for emotions than for actions. Across the studies, desire and emotion explanations emerged early and often, reflecting the primacy of these constructs in the children's understanding of psychological causality. Results are discussed in terms of their implications for developmental mechanism. 相似文献
