AbstractThe 50-minute hour is a feature of psychoanalytic work that is most commonly discussed in the context of case reports. This paper examines it as a concept. The author starts by describing the origin of the 50-minute hour and its development as an element of the psychoanalytic setting or framework. Next, he considers the significance of the clock as a relational factor in the session and reflects on the alienness of the time of day to the unconscious, and the consequences of this alienness. He then uses a clinical example to illustrate the phenomenon of the stretching effect of time in analytic sessions. Finally, the author demonstrates how cleverly the 50-minute hour excises the time needed for unconscious processes from our accelerated present; he shows that it challenges the social convention of time, and has a structuring effect in that it “times” psychic processes. 相似文献

Despite the robustness of semantic priming (e.g., cat–DOG), the test-retest and internal reliabilities of semantic priming effects within individuals are surprisingly low. In contrast, repetition priming (e.g., dog–DOG) appears to be far more reliable across a range of conditions. While Stolz and colleagues attribute the low reliability in semantic priming to uncoordinated automatic processes in semantic memory, their use of unmasked priming paradigms makes it difficult to fully rule out the influence of strategic processes. In the present study, we explored the reliability of semantic and repetition priming when primes were heavily masked and cannot be consciously processed. We found that masked repetition, but not semantic, priming effects showed some degree of reliability. Interestingly, skilled lexical processors (as reflected by vocabulary knowledge and spelling ability) also produced larger masked repetition priming effects. 相似文献

Inverting scenes interferes with visual perception and memory on many tasks. Might scene inversion eliminate boundary extension (BE) for briefly-presented photographs? In Experiment 1, an upright or inverted photograph (133, 258, or 383?ms) was followed by a 258 ms masked interval and a test photograph showing the identical view. Test photographs were rated as “same”, “closer”, or “farther away” (5-point scale). BE was just as great for inverted as upright views at the 133 and 383 ms durations, but surprisingly was greater for inverted views at the 258 ms duration. In Experiment 2, 258-ms views yielded greater BE when the study photographs were always tested in the opposite orientation, indicating that the difference in BE was related to encoding. Results suggest that scene construction beyond the view boundaries occurs rapidly and is not impeded by scene inversion, but that changes in the relative quality of visual details available for upright and inverted views may sometimes yield increased BE for inverted scenes. 相似文献

Cognitive scientists have identified a wide range of biases and heuristics in human decision making over the past few decades. Only recently have bioethicists begun to think seriously about the implications of these findings for topics such as agency, autonomy, and consent. This article aims to provide an overview of biases and heuristics that have been identified and a framework in which to think comprehensively about the impact of them on the exercise of autonomous decision making. I analyze the impact that these biases and heuristics have on the following dimensions of autonomy: understanding, intentionality, absence of alienating or controlling influence, and match between formally autonomous preferences or decisions and actual choices or actions. 相似文献

Prior research has documented the problematic community response to sexual assault: the majority of sexual assaults reported to police are never prosecuted. Social dominance theory suggests that this response is a form of institutional discrimination, intended to maintain existing social structures, and that police personnel likely draw upon shared ideologies to justify their decision‐making in sexual assault case investigations. This study drew upon social dominance theory to examine how police justified their investigatory decisions to identify potential leverage points for change. The study revealed that the likelihood of a case referral to the prosecutor increased with each additional investigative step completed; of the different types of justifications provided by police for a less‐than‐thorough investigative response and stalled case, blaming the victim for the poor police investigation proved to be the most damaging to case progression; and the type of explanation provided by police was impacted by specific case variables. As suggested by social dominance theory, the study demonstrates that police rely on several different mechanisms to justify their response to sexual assault; implementing criminal justice system policies that target and interrupt these mechanisms has the potential to improve this response, regardless of specific case factors. 相似文献

Human and automated tutors attempt to choose pedagogical activities that will maximize student learning, informed by their estimates of the student's current knowledge. There has been substantial research on tracking and modeling student learning, but significantly less attention on how to plan teaching actions and how the assumed student model impacts the resulting plans. We frame the problem of optimally selecting teaching actions using a decision‐theoretic approach and show how to formulate teaching as a partially observable Markov decision process planning problem. This framework makes it possible to explore how different assumptions about student learning and behavior should affect the selection of teaching actions. We consider how to apply this framework to concept learning problems, and we present approximate methods for finding optimal teaching actions, given the large state and action spaces that arise in teaching. Through simulations and behavioral experiments, we explore the consequences of choosing teacher actions under different assumed student models. In two concept‐learning tasks, we show that this technique can accelerate learning relative to baseline performance. 相似文献

身体意象是个体在意识层面对与身体有关的知觉、态度及信念,它的稳定性与可塑性一直存在争论。本研究使用方位追踪仪、数据手套及投影仪,通过2个实验考查虚拟手错觉中距离参照系对身体拥有感的影响。实验1在虚拟环境中采用经典橡胶手错觉的变式,考察同步性和虚拟手位置对拥有感的影响;实验2引入距离参照系,考察在不同参照条件下被试对同一个位置的虚拟手在不同同步情况下的拥有感错觉。研究结果发现:(1)无论是同步性还是距离都会对虚拟手错觉中的拥有感产生影响,即同步比不同步条件下、距离近比距离远条件下拥有感显著;(2)不同的距离参照系对同一位置的拥有感体验影响差异显著,先近后远的呈现方式会减弱错觉而先远后近的呈现方式则会加强错觉。这一发现与身体拥有感是受稳定的身体意象调节的假设并不一致。 相似文献

We asked participants to make simple risky choices while we recorded their eye movements. We built a complete statistical model of the eye movements and found very little systematic variation in eye movements over the time course of a choice or across the different choices. The only exceptions were finding more (of the same) eye movements when choice options were similar, and an emerging gaze bias in which people looked more at the gamble they ultimately chose. These findings are inconsistent with prospect theory, the priority heuristic, or decision field theory. However, the eye movements made during a choice have a large relationship with the final choice, and this is mostly independent from the contribution of the actual attribute values in the choice options. That is, eye movements tell us not just about the processing of attribute values but also are independently associated with choice. The pattern is simple—people choose the gamble they look at more often, independently of the actual numbers they see—and this pattern is simpler than predicted by decision field theory, decision by sampling, and the parallel constraint satisfaction model. © 2015 The Authors.
