The study of body motion in social settings is a relatively unexplored area of human behaviour. In this study an attempt was made to develop a rational model for information control under conditions of uncertainty which could be applied to gross body movement during interaction. The theory specified that body motion would be a function of the subject's perception of the probability that his behaviour might violate expectations and lead to punishments. It was hypothesized that subjects who experienced uncertainty about expectations of others when in the presence of important others would inhibit body motion. It was further hypothesized that the relative use of different body parts would be a function of the experimental condition. An experiment was designed in which subjects were photographed on motion picture film while being interviewed by a role player who assumed different statuses in different experimental conditions. The amount of uncertainty in a condition was manipulated by the selection of subjects and by the instructions given to them during the experiment. The first hypothesis was supported although the converse of the hypothesized relationship was not and in fact presented an anomalous difference. The second hypothesis was not supported although differences are considerable and. in the expected direction. / Arts, Faculty of / Anthropology, Department of / Graduate

If movement control is afforded through the advance planning, or preprogramming, of upcoming actions, then one of the behavioral outcomes should be an increase in reaction time (RT) as the movement becomes more complex. In some situations, however, RT does not increase across levels of complexity, rather it remains invariant. In these cases, on-line preparation is typically inferred. That is, the sequence is said to be prepared in parts throughout the movement, as opposed to entirely beforehand. Given that there is some planning occurring during the sequence, then evidence of this process should be apparent within the movement itself. Three such dependent variables appear to provide such evidence. Specifically, the number of times the underlying accelerations cross the zero line within the movement, the number of "significant deviations" within the acceleration trace, and the length of time for which the muscles are active (as measured by EMG) in relation to the duration of the movement. In the present experiment, then, these variables were measured in addition to the time required to prepare and initiate a movement performed under conditions conducive to either preprogramming or on-line preparation. Specifically, the movements were either completed as fast as possible, or at a considerably slower, more controlled speed. Each of the dependent variables displayed evidence of preprogramming in the movements completed at the fast velocity, and on-line preparation in the slower paced movements. Thus, in the slow condition, subjects appeared to rely more heavily on on-line prepared adjustments to produce an accurate outcome. The convergence attained between the various dependent measures lends power to the conclusions regarding hypothesized modes of control within the different speeds of movement. / Education, Faculty of / Curriculum and Pedagogy (EDCP), Department of / Graduate
