Fitts’ law predicts the human movement response time for a specific task through a simple linear formulation, in which the intercept and the slope are estimated from the task’s empirical data. This research was motivated by our pilot study, which found that the linear regression’s essential assumptions are not satisfied in the literature. Furthermore, the keystone hypothesis in Fitts’ law, namely that the movement time per response will be directly proportional to the minimum average amount of information per response demanded by the particular amplitude and target width, has never been formally tested. Therefore, in this study we developed an optional formulation by combining the findings from the fields of psychology, physics, and physiology to fulfill the statistical assumptions. An experiment was designed to test the hypothesis in Fitts’ law and to validate the proposed model. To conclude, our results indicated that movement time could be related to the index of difficulty at the same amplitude. The optional formulation accompanies the index of difficulty in Shannon form and performs the prediction better than the traditional model. Finally, a new approach to modeling movement time prediction was deduced from our research results.

Fitts' law predicts the human movement response time for a specific task by a simple linear formulation, in which the intercept and the slope are estimated from the task's empirical data. This research was motivated by our pilot study, which found that the linear regression's essential assumptions are not satisfied in the literature. Furthermore, the keystone hypothesis in Fitts' law, that the movement time per response will be directly proportional to the minimum average amount of information per response demanded by the particular amplitude and target width, has never been formally tested. Therefore, this study developed an optional formulation derived from fusing the findings in psychology, physics, and physiology for fulfilling the statistical assumptions. An experiment was designed to test the hypothesis in Fitts' law and validate the proposed model. To conclude, our results indicated that movement time could be related to the index of difficulty underlying the same constant amplitude. The optional formulation accompanies the index of difficulty in Shannon form robustly performs the prediction better than the traditional model across studies. Finally, a new approach to modeling movement time prediction is deduced from our research results

The meaning of the human movement response ( M) to inkblot stimuli was explored in terms of correlations between children's M productions and the attributes of their parents in 119 families. M scores were available for the family members; and for each parent there were also measures of personality, values, and childrearing attitudes. A number of the parent-child correlational patterns were congruent with Rorschach's theories concerning the significance of M.

The relationship between children's perception of human movement on inkblots (the M response) and two aspects of their inhibitory behavior was investigated. Differences in the fantasy correlates of children's and adult M perception were discussed, as was the possibility that different psychological processes mediate inhibitory behavior at different ages.

12 cheerleaders and drum majorettes gave significantly more exhibitionistic M on the Rorschach than a control group of coeds matched on total number of M. However, the difference between these groups on the Hand Test EXH score was even more pronounced, leading to the tentative conclusions that: (1) M tends to be expressed behaviorally but that (2) M per se is not a necessary condition for the occurrence of organized and predictable behavior. These findings were discussed within the context of Structural Analysis.

8 student drama majors gave significantly more exhibitionistic M on the Rorschach than a matched control group. Results were construed as supporting Piotrowski's interpretation of the human movement response. Additional connotations of M were suggested.
