An old problem: how can we distinguish between conscious and unconscious knowledge acquired in an implicit learning task?

A long lasting debate in the field of implicit learning is whether participants can learn without acquiring conscious knowledge. One crucial problem is that no clear criterion exists allowing to identify participants who possess explicit knowledge. Here, we propose a method to diagnose during a serial reaction time task those participants who acquire conscious knowledge. We first validated this method by using Stroop-like material during training. Then we assessed participants’ knowledge with the Inclusion/Exclusion task (Experiment 1) and the wagering task (Experiment 2). Both experiments confirmed that for participants diagnosed as having acquired conscious knowledge about the underlying sequence the Stroop congruency effect disappeared, whereas for participants not diagnosed as possessing conscious knowledge it only slightly decreased. In addition, both experiments revealed that only participants diagnosed as conscious were able to strategically use their acquired knowledge. Thus, our method allows to reliably distinguish between participants with and without conscious knowledge.     

Automatic activation of individual differences: A test of the gatekeeper model in the domain of spontaneous helping

The influence of stable individual differences on behaviour need not solely rely upon deliberative processes but can also be exerted through automatic associative processes. In this contribution, three studies that illustrate the role of individual differences in automaticity are presented in the domain of helping behaviour. The first study provides evidence both for a double dissociation and for an additive pattern of implicit and explicit measures in predicting relevant altruistic behaviours. The subsequent two studies show that when the concept of altruism is subliminally primed, individual differences in implicit attitudes significantly predict behaviour. The results are in line with the gatekeeper model, and their implications are discussed focusing on the key role of individual differences in modulating automaticity effects.

社交焦虑个体外显与内隐自尊的研究

社交恐惧图式理论、社交恐惧模式、和社交恐惧认知行为模式等认知理论,都认为社交恐惧产生于不良的自我图式。为了探讨社交恐惧个体是否具有不良的自我图式,要求40名高社交恐惧个体和30名低社交焦虑个体完成了自尊量表和内隐联想任务。结果发现：高社交恐惧个体在自尊量表上的得分显著低于低社交恐惧个体,但在内隐自尊上,他们都有着积极的自尊,且无显著差异。这一研究结果不支持社交恐惧的认知理论。根据自我呈现理论讨论了研究结果。     

The Nature of Attitude

ABSTRACT

Previous research has shown that acute alcohol consumption is associated with negative responses toward outgroup members such as sexual minorities. However, simple alcohol cue exposure without actually consuming alcohol also influences social behavior. Hence, it was reasoned that priming participants with words related to alcohol (relative to neutral words) would promote prejudiced attitudes toward sexual minorities. In fact, an experiment showed that alcohol cue exposure causally led to more negative implicit attitudes toward lesbians and gay men. In contrast, participants’ explicit attitudes were relatively unaffected by the priming manipulation. Moreover, participants’ typical alcohol use was not related to their attitudes toward lesbians and gay men. In sum, it appears that not only acute alcohol consumption but also the simple exposure of alcohol cues may promote negative views toward lesbians and gay men.     

Adaption-Innovation and Self-Esteem

Abstract

Psychosocial factors that may influence subjective well-being were examined. A random sample of 581 Chinese adults living in a metropolitan Taiwanese city completed questionnaires concerning demographic variables, personality traits, life stress, and social support. The results of multivariate analyses indicated that (a) extraversion and social support were related to better mental health, whereas neuroticism and stress were related to poorer mental health; (b) older age, better education, and social support were related to higher life satisfaction, whereas neuroticism and stress were related to lower life satisfaction; and (c) older age, extraversion, and social support were related to higher happiness, whereas neuroticism was related to lower happiness.     

Emotional enhancement of immediate memory: Positive pictorial stimuli are better recognized than neutral or negative pictorial stimuli

We examined emotional memory enhancement (EEM) for negative and positive pictures while manipulating encoding and retrieval conditions. Two groups of 40 participants took part in this study. Both groups performed immediate implicit (categorization task) and explicit (recognition task) retrieval, but for one group the tasks were preceded by incidental encoding and for the other group by intentional encoding. As indicated by the sensitivity index (d'), after incidental encoding positive stimuli were easier to recognize than negative and neutral stimuli. Participants' response criterion was more liberal for negative stimuli than for both positive and neutral ones, independent of encoding condition. In the implicit retrieval task, participants were slower in categorizing positive than negative and neutral stimuli. However, the priming effect was larger for emotional than for neutral stimuli. These results are discussed in the context of the idea that the effect of emotion on immediate memory enhancement may depend on the intentionality to encode and retrieve information.     

Discrepancies Between Implicit and Explicit Self‐concepts of Intelligence Predict Performance on Tests of Intelligence

Three studies investigated the correspondence between implicit and explicit self‐concepts of intelligence and how that correspondence is related to performance on different intelligence tests. Configurations of these two self‐concepts were found to be consistently related to performance on intelligence tests in all three studies. For individuals who self‐reported high intelligence (high explicit self‐concept), a negative implicit self‐concept (measured with the Implicit Association Test) led to a decrease in performance on intelligence tests. For participants whose self‐report indicated a low self‐concept of intelligence, positive automatic associations between the self and intelligence had a similar effect. In line with a stress hypothesis, the results indicate that any discrepant configuration of self‐concepts will impair performance. Importantly, the prediction of performance on intelligence tests by the self‐concept of intelligence was shown to be independent of self‐esteem (Study 3).

内隐自尊与外显自尊关系的新认识

内隐自尊和外显自尊是自我评价体系中两个非常重要的结构。以往研究基于统计独立性、自身发展性以及双认知系统等角度提出内隐自尊和外显自尊是两个相互独立的结构。但是,越来越多的证据表明,在改善测验工具、动机因素和研究方法之后,内隐自尊与外显自尊显著相关,并且两者之间的关系得到神经机制的佐证。虽然内隐自尊和外显自尊是两个不同的结构,但是它们并不是简单独立关系,而是紧密联系和相互作用于个体的自我评价。     

小学生义符一致性意识的发展研究

采用类别一致性判断任务考察汉语儿童义符一致性意识的发展特征。结果表明：(1)儿童的义符一致性意识随着年级增长而提高。三年级儿童尚未获得一致性意识, 四年级儿童初步具备义符一致性意识, 五年级儿童的义符一致性意识获得了长足的发展, 六年级儿童获得了完善的义符一致性意识。(2)义符一致性意识与认知发展水平、已有知识及加工策略有密切关系。应该有意识地培养儿童的义符一致性意识。     

Consistency of adults’ earliest memories across two years

ABSTRACT

The consistency of earliest memories in content, dating, and memory qualities was investigated. A total of 84 (27 males; M_age?=?24.93, SD?=?1.36) adults reported earliest memories, estimated ages, and rated their recollections on memory qualities with a two-year time lag. At Time 2, their original reports at Time 1 were presented and they were asked to report whether the earliest memories they recalled at Time 2 were the same. Fifty-six per cent of the participants reported the same earliest memories and those remembering the same events had earlier memories than those remembering different ones. Although no significant differences were observed in estimated ages on the basis of mean ages, a predating bias of later memories and a tendency to postdate earlier memories were observed on the basis of a 48-month cut-off point. Thus, how the data is analysed is critical in detecting dating biases or errors affecting conclusions and interpretations about the dating consistency of earliest memories. Finally, memory qualities of earliest memories displayed a high level of consistency with a two-year time lag regardless of remembering the same versus different event.
