Recognising faces: effects of lighting direction, inversion, and brightness reversal.

When information about three-dimensional shape obtained from shading and shadows is ambiguous, the visual system favours an interpretation of surface geometry which is consistent with illumination from above. If pictures of top-lit faces are rotated the resulting stimulus is both figurally inverted and illuminated from below. In this study the question of whether the effects of figural inversion and lighting orientation on face recognition are independent or interactive is addressed. Although there was a clear inversion effect for faces illuminated from the front and above, the inversion effect was found to be reduced or eliminated for faces illuminated from below. A strong inversion effect for photographic negatives was also found but in this case the effect was not dependent on the direction of illumination. These findings are interpreted as evidence to suggest that lighting faces from below disrupts the formation of surface-based representations of facial shape.     

Emotionally guiding our actions

If emotions have a rational role in action, then one challenge for accounting for how we can act rationally when acting emotionally is to show how we can guide our actions by our emotional considerations, seen as reasons. In this paper, I put forward a novel proposal for how this can be so. Drawing on the interconnection between emotions, cares and caring, I argue that, as the emotional agent is a caring agent, she can be aware of the emotional consideration as a pro tanto reason favouring an action choice and, even, as the reason for which she should act.     

Dispositions,explanation, and behavior 1

According to the theory of dispositions here defended, to have a disposition is to have some (non‐dispositional) property that enters into a law of a certain form. The theory does not have the crucial difficulty of the singular material implication account of dispositions, but at the same time avoids the unfortunate notion of ‘reduction sentences’. It is further argued that no dispositional explanation is one of the covering‐law type; but the theory shows how, for any dispositional explanation! To construct a potential explanation of the covering‐law type. The theory can also be applied fruitfully to human behavior, especially with respect to the issues of reasons and causes and of’ rational’ explanation. The success of the applicability of this theory of dispositions is further evidence of its adequacy.     

Gender Differences in the Relationship of Drinking Motivations and Outcomes

Questionnaire data were used to test the hypothesis that stated motivations for drinking would be more directly related to drinking outcomes among adolescent girls than among adolescent boys. Evidence in support of this hypothesis was found, and we suggest that this gender difference might be due to different norms and role expectations in regard to drinking by boys and men and girls and women in our society.
