The Influence of Facial Characteristics on the Relation between Male 2D:4D and Dominance.

Although relations between 2D:4D and dominance rank in both baboons and rhesus macaques have been observed, evidence in humans is mixed. Whereas behavioral patterns in humans have been discovered that are consistent with these animal findings, the evidence for a relation between dominance and 2D:4D is weak or inconsistent. The present study provides experimental evidence that male 2D:4D is related to dominance after (fictitious) male-male interaction when the other man has a dominant, but not a submissive or neutral face.

Playing a Videogame with a Sexualized Female Character Increases Adolescents' Rape Myth Acceptance and Tolerance Toward Sexual Harassment.

How to trust a perfect stranger: predicting initial trust behavior from resting-state brain-electrical connectivity.

Reciprocal exchanges can be understood as the updating of an initial belief about a partner. This initial level of trust is essential when it comes to establishing cooperation with an unknown partner, as cooperation cannot arise without a minimum of trust not justified by previous successful exchanges with this partner. Here we demonstrate the existence of a representation of the initial trust level before an exchange with a partner has occurred.

An addition to Kurzban et al.'s model: thoroughness of cost-benefit analyses depends on the executive tasks at hand.

Though Kurzban et al.'s model explains a considerable set of empirical findings, it cannot accommodate other results without relying on extra assumptions. We offer an addition to the model, and suggest that cost-benefit analyses themselves depend on executive function, and therefore can be biased.

New methods for assessing the fascinating nature of nature experiences.

In recent years, numerous environmental psychology studies have demonstrated that contact with nature as opposed to urban settings can improve an individual's mood, can lead to increased levels of vitality, and can offer an opportunity to recover from stress. According to Attention Restoration Theory (ART) the restorative potential of natural environments is situated in the fact that nature can replenish depleted attentional resources. This replenishment takes place, in part, because nature is deemed to be a source of fascination, with fascination being described as having an "attentional", an "affective" and an "effort" dimension.

The joint effect of tangible and non-tangible rewards on healthy food choices in children.

This study investigated how a combination of tangible and non-tangible rewards can alter health-related decisions made by children. Children chose between an unhealthy food option (a bowl of potato crisps) and a healthy food option (a bowl of grapes) on two occasions. In the first round, we manipulated the expected tangible reward and praise.
