Moise fut choisi par Dieu avant tout pour la lutte qu'il mena contre l'injustice

The information acquired by it is used to both create a percept of the external world and to guide motor actions. In recent years there has been considerable debate regarding whether the same information is utilized and processed in the same manner in the two tasks. The Duncker Illusion, also known as induced motion, is an illusion of motion that results when there is background movement, and it neatly dissociates true from perceived motion. We examined the open-loop period of smooth eye tracking of a target that had an illusory component to its trajectory due to background motion. It was found that the eyes moved in the direction of background motion and of true target motion but not in the illusory direction, despite the strong percept of illusory motion experienced by all subjects. This finding lends support to the hypothesis of separate neurological pathways for the processing of visual information used to create the conscious percept and visual information used to drive motor actions.

In this study, the authors used computerized testing to describe the profile of shifts in cognition attributable to short-term religious fasting. Multiple cognitive domains were evaluated at midday and late afternoon following complete abstention from eating and drinking beginning at midnight. Cross-domain, fasting-related deficits were found for tasks requiring perception of spatial relations. Fasting-related information processing deficits were found for response time but not accuracy for test levels of intermediate difficulty. Time-of-day effects often reflected poorer afternoon performance. These findings provide a detailed profile of cognitive consequences of food deprivation, affected by time of day, task demands, and type of outcome.
