A study of comparison between rear and lookink glass model-demonstration condition on modeling of sequential gross movement task

Abstract

The first purpose of the present study is to determine the effect of two different model-demonstrations on modeling of a sequential gross movement task. The second one is to clarify the visual search differences between the two models in terms of eye movements during observation. Thirty two undergraduate students (Male = 16, Female = 16) were randomly assigned to one of two expefimenta groups. One is subjective group (SG) -observing the model via VTR in the rear angle of model, and the other is looking-glass group (LGG)-observing the model via VTR in the front angle of model that demonstrated oppositely on the right and left direction of the task just like an image in the mirror. The dependent variables, A) the number of model-demonstrations to recall sequential movements completely and B) frequency, angle, and direction of eye fixation movements.Thus, the location and time of eye fixation, and eye movement patterns during observation at the initial and the final trial were employed. The results indicated as follows: (1) The subjective group showed significantly greater modeling effect in recalling the sequential movements than the looking-glass group. (2) The visual search pattern of the subjective group was characterized by searching the model's back and the periphery of the body. On the other hand, the looking-glass group's search pattern concentrated on the model's upper half of the body, exhibiting more eye movement variation and shorter eye fixation time than the subjective group.
