In Experiment 1a, participants were exposed, over a series of trials, to separate presentations of 2 similar checkerboard stimuli, AX and BX (where X represents a common background). In one group, AX and BX were presented on alternating trials (intermixed), in another, they were presented in separate blocks of trials (blocked). The intermixed group performed to a higher standard than the blocked group on a same-different test. A superiority of intermixed over blocked exposure was also evident in a within-subject design (Experiment 1b) and when the test required discrimination between a preexposed stimulus and the background (e.g., AX vs. X), even if the background changed between preexposure and test (AY vs. Y) (Experiment 2). In Experiment 3, the intermixed/blocked effect was observed when, in preexposure, stimulus presentations were alternated with the background alone (e.g., AX/X). This suggests that the perceptual learning effect is not the consequence of inhibitory associations between unique features but to increased salience of those features. Experiment 4 confirmed this finding and also ruled out an account of the effect in terms of trial spacing. 相似文献

A robust finding in humans and animals is that intermixed exposure to 2 similar stimuli (AX/BX) results in better discriminability of those stimuli on test than does exposure to 2 equally similar stimuli in 2 separate blocks (CX_DX)--the intermixed-blocked effect. This intermixed-blocked effect may be an example of the superiority of spaced over massed practice; in the intermixed, but not the blocked exposure regime, each presentation of a given stimulus (e.g., AX) is separated from the next by the presentation of its partner (BX). Two experiments with human participants replicated the intermixed-blocked effect and showed that the effect was not due to the spacing of exposure trials. A mechanism for the intermixed-blocked effect is proposed, which combines theories from associative learning and memory. 相似文献

Perceived control and emotions: interactive effects on performance in achievement settings 总被引:3,自引:1,他引:2

Individual differences in cognitions and emotions play a critical role in difficult academic situations, such as the transition
into college, a period infused with uncertainty. Perceived academic control (low vs. high) and emotions (course boredom, anxiety,
and enjoyment) were examined to determine how they jointly predicted 620 first-year students’ achievement and attrition over
an entire academic year. It was expected that students’ emotions would moderate the effects of high perceived control on achievement
(final psychology grade, cumulative GPA) and attrition (overall course credits dropped). Regression results revealed several
Perceived Control × Emotion interactions that supported this moderation hypothesis: negative emotions impeded the benefits
of high control (i.e., boredom and anxiety predicted worse performance in high-control students); positive emotions enhanced
the benefits of high control (i.e., enjoyment predicted better performance in high-control students). Conversely, achievement
emotions did not predict performance among low-control students. Together, these findings indicate that for a high level of
perceived control to enhance students’ academic achievement and inhibit attrition, “adaptive” levels of emotions (lower boredom,
lower anxiety, or higher enjoyment) are required. Implications for maximizing academic success among both low- and high-control
students are discussed.

This study examined how rumination and worry experienced within varying contexts of everyday life are associated with current‐moment and cross‐moment indicators of subjective well‐being. We also investigated if, in the context of social interaction, distracted communication uniquely predicts subjective well‐being and mediates the link between perseverative cognition and well‐being. Using experience sampling, we found that the effects of rumination and worry on subjective well‐being were social‐context dependent. Rumination experienced alone, relative to during interaction, was a stronger positive predictor of current and later‐in‐the‐day loneliness. In contrast, worry experienced alone, but not during interaction, negatively predicted later loneliness. Distracted communication accounted for unique variance in current affective well‐being and current and later loneliness, but its role as a mediator was uncertain. 相似文献

The aim of this paper is to explore Merleau‐Ponty’s ambivalent relationship with Kant’s transcendental philosophy. I begin by looking at several points of convergence between Kant and Merleau‐Ponty, focusing on the affinities between Kant’s account of transcendental realism and Merleau‐Ponty’s notion of objective thought. I then show how Merleau‐Ponty’s analysis of Kant’s paradox of asymmetrical objects points to a parallel in Kant’s thought to Merleau‐Ponty’s thesis of the primacy of perception. In the second part of the paper, I show why Merleau‐Ponty believes that, despite the promise of Kant’s thought, he fails to adequately escape from objective thought. After presenting the central claims of the transcendental deduction, I piece together Merleau‐Ponty’s criticism of it by answering three questions: For Merleau‐Ponty, how do we encounter the world prior to reflection? How is experience constituted? And what leads Kant to mischaracterise experience in his own transcendental philosophy? 相似文献

Socially prescribed perfectionism (SPP) is often considered as a key risk factor for disordered eating (DE). However, current conceptualizations of SPP largely assume that this perfectionism pressure is non‐specific (i.e., a global pressure), despite research indicating that for females experiencing DE, female‐dominated groups impose this pressure (as a perceived norm). Furthermore, this relationship may be mediated by a negative reaction to this pressure, in the form of impulsivity (or negative urgency). To date, no research has investigated whether the relationship between SPP and DE is mediated by negative urgency, nor has there been research clarifying how in‐group identification relates to DE, independent of SPP and negative urgency. To address these gaps, we assessed these variables in 147 female dieters (Mage = 25.12 years, SD = 3.08) using a cross‐sectional design. Consistent with our hypotheses, negative urgency fully mediated the link between female‐based SPP and disordered eating, while female‐based in‐group affect (identification) was predictive of disordered eating (although the latter relationship was not sustained in a multiple regression model). These findings suggest that the SPP from other women may relate to DE through increasing negative urgency, and that the link between in‐group (female) affect and DE may be better explained by SPP's link to DE. 相似文献

There has been an assertion in certain parts of the media, especially social media, that the majority of individuals who have engaged in a school shooting were prescribed psychotropic medications prior to the event. To determine if there is any validity to this assertion, the authors of this article reviewed publicly available information regarding individuals involved in “educational shootings” per FBI publications for active shooters from 2000 to 2017. Sources of information included news reports with official citations, official reports regarding events, available court records, and FBI Freedom of Information Act requests. Secondary data‐points were also collected, such as location, number of weapons used, number of victims, legal outcome, and whether the shooter committed suicide. From the information obtained, it appears that most school shooters were not previously treated with psychotropic medications – and even when they were, no direct or causal association was found. 相似文献

Up to one third of the epilepsy population consists of children with cryptogenic localization related epilepsy (CLRE). Unfortunately, the effect of CLRE on the development is still unclear. Behavioral and academic problems have been reported, but no conclusive study concerning the impact of CLRE on neuropsychological functioning is yet published. This study was a systematic cross-sectional open clinical and nonrandomized investigation, which included 68 children with CLRE. Several neuropsychological tests were analyzed and age-related normative values were used as reference. Differences between CLRE and reference values were tested with Paired-Samples t-tests. Z scores were computed to compare the different neuropsychological tests and to inspect whether a characteristic neuropsychological profile exists for CLRE. The Independent-Samples t-test was used to explore which epilepsy factors (seizure type, seizure frequency, age at onset, duration of epilepsy, and drug load) were influencing the cognitive profile of CLRE. There seems to be a characteristic cognitive profile for children with CLRE; children with CLRE experience cognitive difficulties on a wide range of areas-in particular, alertness, mental speed, and memory. Seizure type, seizure frequency, duration of epilepsy, and drug load do not influence this neuropsychological profile. Age at onset was an important risk factor; the earlier the age at onset, the worse the cognitive performance. In spite of the influence of age at onset, the revealed profile can be seen as a stable, independent of temporary factors, neuropsychological profile for children with CLRE. 相似文献

This study examined the effects of felt accountability, political skill, and job tension on job performance ratings. Specifically, we hypothesized that felt accountability would lead to higher (lower) job performance ratings when coupled with high (low) levels of political skill, and that these relationships would be mediated by job tension. Data were gathered at multiple times over a one-year period (i.e., baseline performance, attitudinal variables one month later, supervisor reports of subordinate performance six months and one year after baseline performance was measured). Strong support was shown for the total effects model, whereby political skill moderated felt accountability—job performance ratings, felt accountability—job tension, and job tension—job performance ratings relationships. However, more focused analyses demonstrated that political skill most strongly moderated the job tension—job performance ratings linkage. Implications, strengths and limitations, and directions for future research are provided. 相似文献
