• Abstract:
  The aim of this study was to shed some light on brain injuries following blows to the head by means of the methods of both cognitive psychology and electrophysiology. More precisely, boxers' attention mechanisms and their capacity of orienting towards a significant stimulus were investigated using event related potentials (ERPs) of the brain in dichotic listening situations, before and after a fight. These types of psychological mechanisms are known to be very fundamental both in animals and in humans for protection against environmental dangers. Therefore, it is of great interest to know the level of intensity of a blow to the head that is capable of reducing such survival capacity, even if it is for only a short period of time. More practically, just after a car accident involving a blow to the head, it may be very important to be able to react as quickly as possible to further dangers and this study was thus undertaken in order to assess some of the limits under which normal behavior following head injury remains possible.
