Ease-of-learning judgments are based on both processing fluency and beliefs

Processing fluency influences many types of judgments. Some metacognitive research suggests that the influence of processing fluency may be mediated by participants’ beliefs. The current study explores the influence of processing fluency and beliefs on ease-of-learning (EOL) judgments. In two experiments (Exp 1: n?=?94; Exp 2: n?=?146), participants made EOL judgments on 24 six-letter concrete nouns, presented in either a constant condition (high fluency) with upper-case letters (e.g., BUCKET) or an alternating condition (low fluency) with mixed upper- and lower-case letters (e.g., bUcKeT). After judging words individually, participants studied the words and completed a free recall test. Finally, participants indicated what condition they believed made the words more likely to be learned. Results show constant-condition words were judged as more likely to be learned than alternating condition words, but the difference varied with beliefs. Specifically, the difference was biggest when participants believed the constant condition made words more likely to be learned, followed by believing there was no difference, and then believing the alternating condition made words more likely to be learned. Thus, we showed that processing fluency has a direct effect on EOL judgments, but the effect is moderated by beliefs.     

Memory loss versus memory distortion: The role of encoding and retrieval deficits in Korsakoff patients’ false memories

Recent studies with the Deese/Roediger-McDermott (DRM) paradigm have revealed that Korsakoff patients show reduced levels of false recognition and different patterns of false recall compared to controls. The present experiment examined whether this could be attributed to an encoding deficit, or rather to problems with explicitly retrieving thematic information at test. In a variation on the DRM paradigm, both patients and controls were presented with associative as well as categorised word lists, with the order of recall and recognition tests manipulated between-subjects. The results point to an important role for the automatic/controlled retrieval distinction: Korsakoff patients’ false memory was only diminished compared to controls’ when automatic or short-term memory processes could not be used to fulfil the task at hand. Hence, the patients’ explicit retrieval deficit appears to be crucial in explaining past and present data. Results are discussed in terms of fuzzy-trace and activation-monitoring theories.     

Acute aerobic exercise improves memory across intensity and fitness levels

ABSTRACT

The present study was designed to examine the impact of exercise intensity and aerobic fitness on free recall, judgments of learning (JOLs), and metacognitive accuracy. In Experiment 1, 30 college students engaged in either (1) no exercise, (2) light exercise (55% of predicted maximal heart rate), or (3) moderate exercise (75% of predicted maximal heart rate) on three different days. In Experiment 2, 29 high-fit students (VO₂ max?≥?70th percentile) and 28 low-fit students (VO₂ max?≤?50th percentile) completed sedentary and light exercise conditions. In both experiments, free recall scores significantly increased in the exercise conditions compared with the sedentary condition, but JOL magnitude and metacognitive accuracy were largely unaffected. These results demonstrate that exercise can improve recall at both light and high intensities, and that the benefit can be obtained by individuals regardless of their fitness level.     

Equilibrium Selection,Similarity Judgments,and the “Nothing to Gain/Nothing to Lose” Effect

Rubinstein and Leland have both demonstrated that many observed violations of expected and discounted utility can be explained if people employ similarity judgments to make choices. In this paper, I show that this decision process also explains which equilibria will be selected in single‐shot games with multiple equilibria and implies that play in games will be associated with anomalies in risky choice. Data supporting these predictions are presented. Copyright © 2012 John Wiley & Sons, Ltd.     

Development of implicit and explicit category learning

We present two studies that examined developmental differences in the implicit and explicit acquisition of category knowledge. College-attending adults consistently outperformed school-age children on two separate information-integration paradigms due to children’s more frequent use of an explicit rule-based strategy. Accuracy rates were also higher for adults on a unidimensional rule-based task due to children’s more frequent use of the irrelevant dimension to guide their behavior. Results across these two studies suggest that the ability to learn categorization structures may be dependent on a child’s ability to inhibit output from the explicit system.     

Gender differences in implicit prejudice

In three experiments (n=131), we examined gender differences in implicit (and explicit) racial prejudice employing priming of immigrant and Swedish facial photographs without attention or without awareness. Implicit prejudice was defined as the degree of negativity expressed toward a person described in a subsequent ambiguous story in an impression formation task. We found, contrary to our hypothesis, that women displayed systematically higher implicit prejudice than men in all three experiments, although men scored higher on explicit prejudice than women. The results are discussed against the background of related prejudice research, the dissociation of implicit and explicit prejudice, and gender differences in cognitive functioning, especially in the processing of pictorial stimuli.     

美感对西方绘画无意识加工的影响

采用连续闪烁抑制范式(Continuous Flash Suppression, CFS), 通过比较不同美感的图片的突破抑制时间,考察了美感对西方绘画无意识加工的影响。实验1使用黑白噪音图片, 通过单因素被试内设计考察了高、中、低三种美感等级的彩色西方绘画的突破抑制时间。结果发现, 美感高和美感中等的西方绘画比美感低的西方绘画能更快突破噪音图片的抑制进入意识。实验2考察在彩色噪音图片的抑制下, 美感是否依然影响彩色西方绘画突破抑制的时间。结果发现, 美感不影响西方绘画突破抑制时间, 且突破抑制时间显著长于实验1。这些结果表明美感对西方绘画无意识加工的影响受到双眼竞争的眼间抑制过程的限制, 只有在黑白噪音图抑制的情况下, 美感会影响西方绘画进入意识的速度。与黑白噪音图片相比, 彩色噪音图片可能对颜色信息的抑制更强, 干扰了美感对西方绘画无意识加工的影响。     

文化如何影响道德?文化间变异、文化内变异与多元文化的视角

道德判断与行为具有高度的文化敏感性, 来自不同文化背景、具有不同文化经历的个体, 对于同一道德现象的理解与建构存在显著差异。随着20世纪80年代文化心理学的复兴繁荣和全球化进程的不断深化, 文化视角的道德心理学在当代社会心理学语境中备受关注, 并已开展了初步的理论探索, 积累了大量的实证证据。基于文化心理学的视角, 本文将分别从文化间变异、文化内变异和多元文化三个方面梳理和评述不同文化因素(比如地域、生态、社会阶层等)如何影响个体的道德判断与行为, 期望推动未来研究进一步探索快速而剧烈的文化变迁背景下中国人的道德心理和价值体系已经发生了或正在发生着怎样的演变过程。     

National identification and support for discriminatory policies: The mediating role of beliefs about laïcité in France

In France, laïcité is a legal principle enforcing State secularism. However, research indicates that Modern (vs. traditional) beliefs about laïcité (ML) help legitimate prejudice against minorities. From Social Identity Theory, we hypothesized that ML should be positively linked with national identification, stereotyping, prejudice and support for discrimination. Accordingly, we demonstrate that ML independently predicts support for discriminatory policies (Study 1a, N = 241) and Maghrebi IAT scores (Study 1b, N = 242). ML mediates the link between national identification and Generalized Prejudice (Study 2a, N = 215; Study 2d, N = 114) as well as Support for Discriminatory Policies (Study 2b, N = 250). Experimental corroboration of this mediation was provided (Study 2c, N = 100). An exploratory study showed that priming ML led to more support for discrimination through national identification (Study 3, N = 89). These results reveal the important intergroup regulation feature of ML beliefs in France.     

Relations between emotion,memory encoding,and time perception

This study examined duration judgments for taboo and neutral words in prospective and retrospective timing tasks. In the prospective task, participants attended to time from the beginning and generated shorter duration estimates for taboo than neutral words and for words that they subsequently recalled in a surprise free recall task. These findings suggested that memory encoding took priority over estimating durations, directing attention away from time and causing better recall but shorter perceived durations for taboo than neutral words. However, in the retrospective task, participants only judged durations in a surprise test at the end, and their duration estimates were longer for taboo than neutral words. Present findings therefore suggest that the same emotion-linked memory encoding processes can cause underestimation of durations in prospective tasks but overestimation in retrospective tasks, as if emotion enhances recall of ongoing events but causes overestimation of the durations of those events in retrospect.
