The effect of different attentional strategies on motor efficiency, measured by reaction-response time components, has historically been based on memory-drum construct theory, which implied limited attention and motor-response processing. The present study contrasts these principles by using a recording system and automatic analysis of reaction-response parameters. A within-subject design allowed detailed observation of the frequency of each preparatory set within each parameter and with control of the effects of practice. Analysis indicates (a) practice changes the effects of the attentional strategies on the components of reaction response but not the actual movement; (b) the motor-set strategy produces shorter movement times and, inversely, higher motor reaction times; and (c) the motor-sensory set integrated strategy produces improvements on each component of the reaction response. These findings suggest the memory-drum construct theory needs revision and should be based on other attentional models.

A study was performed to determine the extent to which flight-relevant information on instruments peripheral to fixation is extracted and used during fixed-wing instrument flight. Twenty student and twenty instructor pilots flew a series of missions in a fixed-wing flight simulator which was interfaced with an eye-tracker. In one mission flight-relevant information was removed from instruments peripheral to fixation while in the other mission peripheral information was intact. Pilots' performance was degraded and eye scan strategies were modified when peripheral information was removed. Furthermore, in several situations instructor pilots' performance was more adversely influenced by the removal of peripheral information than was student pilots' performance. The data are discussed in terms of attentional strategies during flight.

An asymmetry of attention was observed when subjects attempted to perform concurrent, relatively independent tasks with the two hands: right-handed subjects performed very much better on a dual task which required them to follow the beat of a metronome with the left while tapping as quickly as they could with the right than with the converse arrangement. It is suggested that attentional strategies which have evolved to allow guidance of interdependent skilled bimanual activities are also used when subjects attempt to perform relatively independent concurrent bimanual movements, which are not observed in the naturally occurring motor repertoire. Thus, interactions between hand, hand preference and nature of task are an important factor in dual task performance.
