Researchers have been studying the effects of acceleration on humans for over 50 years. In that time we have acquired much information about the effects of positive Gz on human physiology, and yet, we know very little about its effects on cognitive abilities. The purpose of the present paper is to underscore the need for additional research in this area. First, a description of the G environment is presented. This is followed by a brief review of some of the relevant literature on psychomotor performance and reaction time. The papers ends with a survey of topics that beg experimental attention using the information processing model as its guide.
