The purposes of the study were (1) to validate five selected supportive and five selected non-supportive nonverbal movements, and (2) to determine the effects of the nonverbal expressions upon subjects' learning of a gross motor skill. Subjects were twenty-eight college women who met the established criteria. The testing instrument was the Bachman Ladder. Fourteen subjects received the supportive-- non-supportive nonverbal treatment sequence; fourteen subjects received the reverse treatment sequence. Subjects numerically ranked the degree of treatment following each experimental session. Data were analyzed by analysis of variance method. Alpha was .05. Conclusions of this study were (1) that nonverbal supportive and non-supportive treatments do not significantly affect gross motor learning, and (2) the selected expressions are valid techniques for nonverbal communications.

The purpose of the investigation was to determine the effect of the tonic neck posture upon fatigue induced by exhaustive exercise of the knee extensor muscles of college women. The subjects were college females enrolled in physical education activity classes at North Texas State University. The F ratio was used to determine significance of the difference in fatigue measures in the three head positions. The results of the present investigation revealed no statistically significant difference between the three head positions with respect to their influence on endurance of the leg extensors. Conclusions were that the tonic neck reflex does not facilitate or inhibit leg extensor endurance.
