The present research is based on the assumption that people differ in their responsiveness to incentives and threats. In two experiments we examined whether the trait corresponding to the responsiveness to threats (avoidance motive) and the trait corresponding to the responsiveness to incentives (approach motive) influence voluntary motor behavior toward or away from stimuli. In Experiment 1, stimuli consisted of positive and negative words within a lexical decision task. Participants moved their arms backward in order to withdraw from the stimuli or forward in order to approach them. In Experiment 2, participants responded with forward or backward arm movements to neutral sounds coming from behind or in front of them. The main dependent variable was the strength of the approach and avoidance movements. In both experiments this variable was related to participants' avoidance-motive disposition but not to their approach-motive disposition. Avoidance-motivated individuals generally showed more forceful avoidance movements than approach movements. There was no effect of stimulus valence on the strength of the movements in Experiment 1. Furthermore, the results of Experiment 2 suggest that it is not the physical direction (forward or backward) but rather the movement's effect of distance reduction (approach) or distance increase (avoidance) in regard to the stimulus that defines a movement as an approach or an avoidance movement. 相似文献

In this article we discuss the notion of a linguistic universal, and possible sources of such invariant properties of natural
languages. In the first part, we explore the conceptual issues that arise. In the second part of the paper, we focus on the
explanatory potential of horizontal evolution. We particularly focus on two case studies, concerning Zipf’s Law and universal
properties of color terms, respectively. We show how computer simulations can be employed to study the large scale, emergent,
consequences of psychologically and psychologically motivated assumptions about the working of horizontal language transmission. 相似文献

At the heart of the current debate about immigration we find a conflict of convictions. Many people seem to believe that a country has a right to decide who to let in and who to keep out, but quite often they appear equally committed to the view that it is morally wrong to expel someone from within the borders of their country if that would seriously jeopardise the person in question. While the first conviction leads to stricter border controls in an attempt to prevent would-be immigrants from entering the country illegally, the latter conviction ensures that aliens with a legitimate claim on protection will not be removed forcibly. It is not strange, therefore, that the task of pinning down a morally sound immigration policy is such an elusive enterprise.
In this paper I take it for granted that no electorate would be prepared to accept the kind of policy they ought to, and that we in consequence will continue to let in as few immigrants as is currently the case. Given this constraint I argue against two common assumptions concerning a viable immigration policy. First, granted that certain conditions are satisfied, professional smugglers should not face legal sanctions for bringing asylum seekers to a potential host country. Second, countries that limit immigration should not treat people seeking family reunion preferentially or on a par with other immigrants, but rather act so as to maximise the number of refugees allowed to enter. 相似文献

Previous research has shown that normative appeals to engage in environmentally friendly behavior were most effective when they were accompanied by a provincial norm (e.g., when norms matched individuals’ immediate situational circumstances). Analyzing hotel guests’ towel-use during their stay, the current study tests whether messages employing provincial norms were more effective in reducing towel-use than standard environmental messages. In line with previous findings, guests of two hotels used significantly fewer towels when provincial normative appeals—rather than standard environmental messages—were communicated. These findings corroborate to the body of research demonstrating the power of social norms on environmental behavior. 相似文献
