In a serial pointing task to three unequidistant, unequiprobable targets, the moving picture record of the subject's hand movements shows, before each pointing movement, a repositioning of the hand near the median plane of the working panel when the subject sees the targets and near the more frequently used target when only proprioceptive information is available.

Two tasks (simple and choice reaction time) were examined while varying three types of stressors (shock, threat of shock, and noise) and the stressor task relationship (i.e., task-related stress, task-unrelated stress, and no-stress). Four specific hypotheses were tested and 3 were supported in the simple reaction-time task. There were no significant differences among stressors for either task, although greater differences were reported in the simple than in the choice reaction-time task. A significant difference between the “task-relatedness” of stress levels in the simple task was interpreted as possibly due to a “coping” or “protective adaptive mechanism” in which increases in performance serve to reduce stress. Practical applications were examined.

Choice reaction time and movement time were measured in a discrete visuo-manual pointing task. Two movement amplitudes (7.5 cm and 30 cm) and two target widths (1.5 cm and 6 cm) were used in all possible combinations. Movement time varied according to movement amplitude and to target width. However, some departure from the linear relationship between movement difficulty and movement time, known as the Fins' law, was observed. Choice RT varied according to movement amplitude, whereas target width influenced choice RT for short-amplitude movements but not for long-amplitude movements. It is concluded that the previously reported relationship between movement difficulty and choice RT primarily results from variations in movement amplitude.
