Busy doing nothing: Evidence for nonaction-effect binding

Research on voluntary action has focused on the question of how we represent our behavior on a motor and cognitive level. However, the question of how we represent voluntary not acting has been completely neglected. The aim of the present study was to investigate the cognitive and motor representation of intentionally not acting. By using an action-effect binding approach, we demonstrate similarities of action and nonaction. In particular, our results reveal that voluntary nonactions can be bound to an effect tone. This finding suggests that effect binding is not restricted to an association between a motor representation and a successive effect (action-effect binding) but can also occur for an intended nonaction and its effect (nonaction-effect binding). Moreover, we demonstrate that nonactions have to be initiated voluntarily in order to elicit nonaction-effect binding.     

Individualism and Collectivism: Implications for Women

This essay examines the nature and dynamics of individualism and collectivism as social and interpersonal phenomena. It considers the importance of affirming the true self as a key feature of individualism as conceived by Donald Capps. By means of cultural and gender analysis, the essay explores aspects of self-affirmation among women, especially Korean American women in both individualist and collectivist societies. It ultimately proposes a “self-affirming collectivism” that promotes the authentic individual self as imago Dei whose unique identity is expressed within community.     

《易经》:早期儒家的形上学与意识进化学

相关资料初步表明,在中国古代,客观地把握人性及人与宇宙交互作用的自觉与努力业已发生。本文试图阐明《易经》的思维理路,借此思维理路,《易经》不仅塑造和影响了早期儒家形上学,而且也塑造和影响了诸如意识研究,尤其是意识学之类的当代研究领域。《易经》的发展及其在西方的传播,正说明了这一点。意识学研究人性,思考存在的其他领域。在这些方面,意识学与《周易》是相通的。将意识学同中国古代思想相比较可以看出,我们现在所研究的意识学在中国古代思想中早已有之。基于这一历史事实,我们有必要在意识学的起始处研究意识学。在意识学研究中,意识进化学是一个不可或缺的、必须进行研究的内容。我们可以通过《易经》来探索意识的进化。     

Estimating the quantitative relation between incongruent information and response time

In Eriksen's flanker paradigm, participants' responses are slower and more error-prone when task-relevant and simultaneously available task-irrelevant cues are incongruent. The influence of task-irrelevant information decreases as its distance from the task-relevant information increases. Here, we manipulated the quantity of task-irrelevant information while keeping the distance constant. We asked whether when the impact on response selection processes was stronger the more incongruent information was available, or whether the impact on response selection depended only on its presence or absence. We conducted an experiment, in which subjects had to discriminate the direction of motion of a central point-light-walker that was flanked by two, four, or eight point-light-walkers at an equal distance from the center. The experiment showed that reaction times increased with the number of incongruent walkers. This effect was modulated by the total number of walkers, showing that the effect of incongruent information saturates when the display is cluttered.     

Influence of attended repetition trials on negative priming in younger and older adults

A lengthened response time when a distractor becomes a target, called negative priming, is an undisputed phenomenon in selective attention, yet just what the underlying mechanism responsible for negative priming is has not been resolved. In this study, the proportion of attended repetition trials was manipulated in order to test the predictions of three theories that have been proposed for explaining spatial negative priming: distractor suppression (e.g., Tipper, 1985), episodic memory retrieval (e.g., Neill, Valdes, &; Terry, 1995), and novelty bias (e.g., Milliken, Tipper, Houghton, &; Lupiáñez, 2000). The results supported the proposal that a novelty bias, which is flexible and can be overridden, is the primary mechanism responsible for priming in spatial tasks. Memory retrieval obscured the novelty bias for target processing, was more selective in older adults, and did not affect distractor processing. Novelty bias and distractor suppression may share the same inhibitory attentional mechanism.

Perceptual multistability in figure-ground segregation using motion stimuli

In a series of experiments using ambiguous stimuli, we investigate the effects of displaying ordered, discrete series of images on the dynamics of figure-ground segregation. For low frame presentation speeds, the series were perceived as a sequence of discontinuous, static images, while for high speeds they were perceived as continuous. We conclude that using stimuli varying continuously along one parameter results in stronger hysteresis and reduces spontaneous switching compared to matched static stimuli with discontinuous parameter changes. The additional evidence that the size of the hysteresis effects depended on trial duration is consistent with the stochastic nature of the dynamics governing figure-ground segregation. The results showed that for continuously changing stimuli, alternative figure-ground organizations are resolved via low-level, dynamical competition. A second series of experiments confirmed these results with an ambiguous stimulus based on Petter’s effect.
