“…In navigating the aircraft, the pilot operates a control stick and therefore has control over the onset and offset of G. In many laboratory tests, tracking with a control stick has no impact on the course of G exposure. A review by Grether (1971) indicates the harmful effects of G on tracking performance are attenuated under closed-loop conditions.…”

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.Today's pilots of high performance aircraft often find themselves in a unique and stressful environment. They are required to command and operate some of the most complex machines ever created and maneuver them through difficult and often hostile territory at tremendous speeds. Moreover, they must do this while enduring periodic insult to the body in the form of unusually high G forces.such an environment requires extensive training. Much has been written about the cognitive demands posed by increasing levels of technology in the cockpit and the skills needed to execute missions without incident. And yet, virtually nothing is known about how G stress affects the pilot's cognitive abilities.

“…In most instances, results indicate that response times in both simple and choice paradigms increase with increases in G exposure (Chambers, 1963;Grether, 1971). However, Canfield, Comrey, Wilson, and Zimmerman (1950) found that the effects of G on response times dissipated with successive exposures.…”

“…There are a few review articles that summarize the available research on human performance under high-g. An early review was conducted by Grether in 1971. He summarized the evidence showing that tracking and flight control exhibits progressive impairment as +gz increases, and also maintained that early research suggested that manual output functions may be more susceptible to acceleration-induced mechanical impairment than intellectual/central nervous system impairment (at least at lower +gz levels).…”
