Religions commonly are taken to provide general orientation in leading one's life. We develop here the idea that religions also may have a much more concrete guidance function in providing systematic decision biases in the face of cognitive-control dilemmas. In particular, we assume that the selective reward that religious belief systems provide for rule-conforming behavior induces systematic biases in cognitive-control parameters that are functional in producing the wanted behavior. These biases serve as default values under uncertainty and affect performance in (...) any task that shares cognitive-control operations with the religiously motivated rule-conforming behavior the biases were originally developed for. Such biases therefore can be unraveled and objectified by means of rather simple tasks that are relatively well understood with regard to the cognitive mechanisms they draw on. (shrink)

A previous study has shown that the degree of trust into others might be biased by inducing either a more “inclusive” or “exclusive” cognitive-control mode. Here, we investigated whether the degree of interpersonal trust can be biased by environmental factors, such as odors, that are likely to impact cognitive-control states. Arousing olfactory fragrances (e.g., peppermint) are supposed to induce a more exclusive, and calming olfactory fragrances (e.g., lavender) a more inclusive state. Participants performed the Trust Game, which provides an index (...) of interpersonal trust by assessing the money units one participant (the trustor) transfers to another participant (the trustee), while being exposed to either peppermint or lavender aroma. All participants played the role of trustor. As expected, participants transferred significantly more money to the alleged trustee in the lavender as compared to the peppermint and no aroma conditions. This observation might have various serious implications for a broad range of situations in which interpersonal trust is an essential element, such as cooperation (e.g., mixed-motives situations), bargaining and negotiation, consumer behavior, and group performance.

Buddhism has captured the imagination of many in the modern (Western) world. Recently, scientists have seemed eager to discover whether claims about Buddhist meditation can be verified experimentally. Brain research is beginning to produce concrete evidence that mental discipline and meditative practice can change the workings of the brain and allow practitioners to achieve different levels of awareness, as measurable for instance in reaction times to stimuli. The goal of this section of articles in Zygon is to address recent developments (...) in this area. The contributions address a wide array of questions, although they certainly do not cover the whole ground of what one may consider “problems” of meditation. Yet, we believe that the issues addressed here have widespread implications and that they constitute a strong argument for the richness of the meditation domain. (shrink)
