Responses are faster when the side of stimulus and response correspond than when they do not correspond, even if stimulus location is irrelevant to the task at hand: the correspondence, spatial compatibility effect, or Simon effect. Generally, it is assumed that an automatically generated spatial code is responsible for this effect, but the precise mechanism underlying the formation of this code is still under dispute. Two major alternatives have been proposed: the referential-coding account, which can be subdivided into a static version and an attention-centered version, and the attention-shift account. These accounts hold clear-cut predictions for attentional cuing experiments. The former would assume a Simon effect irrespective of attentional cuing in its static version, whereas the attention-centered version of the referential-coding account and the attention-shift account would predict a decreased Simon effect on validly as opposed to invalid cued trials. However, results from previous studies are equivocal to the effects of attentional cuing on the Simon effect. We argue here that attentional cueing reliably modulates the Simon effect if some crucial experimental conditions, mostly relevant for optimizing attentional allocation, are met. Furthermore, we propose that the Simon effect may be better understood within the perspective of supra-modal spatial attention, thereby providing an explanation for observed discrepancies in the literature. 相似文献

According to the Perceptual Symbols Theory of cognition ( Barsalou, 1999 ), modality-specific simulations underlie the representation of concepts. A strong prediction of this view is that perceptual processing affects conceptual processing. In this study, participants performed a perceptual detection task and a conceptual property-verification task in alternation. Responses on the property-verification task were slower for those trials that were preceded by a perceptual trial in a different modality than for those that were preceded by a perceptual trial in the same modality. This finding of a modality-switch effect across perceptual processing and conceptual processing supports the hypothesis that perceptual and conceptual representations are partially based on the same systems. 相似文献

The Five-Factor Personality Inventory (FFPI) assesses a person's position on the (Dutch) psycholexically based Big Five factors: Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Autonomy. FFPI factor scores are reliable and valid if ratings are made by adults. The present study yields preliminary evidence of whether young adolescents provide reliable and valid self-ratings on this instrument or whether this depends on their cognitive ability level. The sample consisted of a large and representative cohort of youngsters with a mean age of 13 years. The adult structure of the FFPI was generally well replicated, across all ability levels represented in the study. The findings further suggest that young adolescents' factor scores are construct-valid and sufficiently reliable to be used in (group) research settings. However, for reports on individual profiles and decision making, an adolescent's cognitive ability level would need to be rather high. Even then, measuring Autonomy seems challenging. 相似文献

This article analyzes the topic of leadership from an evolutionary perspective and proposes three conclusions that are not part of mainstream theory. First, leading and following are strategies that evolved for solving social coordination problems in ancestral environments, including in particular the problems of group movement, intragroup peacekeeping, and intergroup competition. Second, the relationship between leaders and followers is inherently ambivalent because of the potential for exploitation of followers by leaders. Third, modern organizational structures are sometimes inconsistent with aspects of our evolved leadership psychology, which might explain the alienation and frustration of many citizens and employees. The authors draw several implications of this evolutionary analysis for leadership theory, research, and practice. 相似文献

In two experiments, we used a Pavlovian differential conditioning procedure to induce craving for chocolate. As a result of repeated pairing with chocolate intake, initially neutral cues came to elicit an automatic approach tendency in a speeded stimulus-response compatibility reaction time task. This automatic approach tendency, moreover, seemed to be sensitive to manipulations of extinction and renewal in the Pavlovian conditioning procedure. These findings corroborate and extend previous reports of automatic approach tendencies elicited by substance-relevant cues in addiction, while controlling for alternative accounts for such observations. Moreover, our data lend support to and extend learning models of cue-induced craving and addiction. Finally, we argue that the procedure we present here provides an ecologically valid behavioural tool that allows studying processes involved in cue-induced craving, addiction and relapse without relying on verbal report. 相似文献

The main objective of the Flemish research project ‘Nanotechnologies for tomorrow’s society’ (NanoSoc) is to develop and try
out an interactive process as a suitable methodology for rendering nanoresearchers aware of underlying assumptions that guide
nanotech research and integrating social considerations into the research choices they face. In particular, the NanoSoc process
should sustain scientists’ capacities to address growing uncertainties on the strategic, scientific and public acceptance
level. The article elaborates on these uncertainties and involved dilemmas scientists are facing and proposes a process approach which addresses strategic uncertainty by alternating between ‘visioning’ and ‘technology assessment’; a process design which manages complexity by promoting reflexivity among scientists by exposing them to deliberations in civil society (social
experts, stakeholders, citizens) on plausible futures with nanotechnologies; and as an answer to societal ambivalence, certain
process quality requirements such as an attitude of perplexity or openness towards ‘plurality’ and an attitude of ‘temporary closure’, both in support
of understanding and learning from differences.

White matter hyperintensities (WMH) are commonly observed in elderly people and may have the most profound effect on executive functions, including working memory. Surprisingly, the Digit Span backward, a frequently employed working memory task, reveals no association with WMH. In the present study, it was investigated whether more detailed analyses of WMH variables and study sample selection are important when establishing a possible relationship between the Digit Span backward and WMH. To accomplish this, the Digit Span backward and additional working memory tests, WMH subscores, and cardiovascular risk factors were examined. The results revealed that performance on the Digit Span backward test is unrelated to WMH, whereas a relationship between other working memory tests and WMH was confirmed. Furthermore, a division between several white matter regions seems important; hyperintensities in the frontal deep white matter regions were the strongest predictor of working memory performance. 相似文献

Using a daily process design, the present study examined relationships between momentary appraisals and emotional experience based on Smith and Lazarus' (1993) theory of emotions (1993). Nine times a day for 2 weeks, participants (N = 33, 23 women) recorded their momentary experience of 2 positive emotions (joy, love) and 4 negative emotions (anger, guilt, fear, sadness) and the core relational theme appraisal contents Smith and Lazarus hypothesized as corresponding to these emotions. A series of multilevel modeling analyses found that the hypothesized relationships between appraisal contents and these emotions were stronger than relationships between contents and other emotions, although appraisals were related to other emotions in many cases. Moreover, there were some individual differences in the strength of these relationships. These results suggest that there are no one-to-one relationships between appraisal contents and specific emotional experiences, and that specific emotions are associated with different appraisal contents, and that specific appraisals are associated with different emotions. 相似文献
