Pointing Accuracy

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.

Midline Crossing

The purpose of this study was to determine if adults with spastic diplegic cerebral palsy (CP) display midline crossing inhibition (MCI) in the lower extremity as measured by choice reaction time (CRT) and movement time (MT) as compared to participants without disabilities. Midline crossing ability was assessed in the standing position using a protocol developed by Eason and Surburg (1993). Both groups were significantly slower in the contralateral direction as compared to the ipsilateral and midline direction as measured by CRT. Results revealed that adults with CP were significantly slower in CRT and MT tasks as compared to participants without disabilities. Assessment of midline crossing ability may provide useful information related to assessment and subsequent treatment as individuals with CP age.

Supplementary Low-Intensity Aerobic Training Improves Aerobic Capacity and Does Not Affect Psychomotor Performance in Professional Female Ballet DancersWe investigated whether 6-week low-intensity aerobic training program used as a supplement to regular dance practice might improve both the aerobic capacity and psychomotor performance in female ballet dancers. To assess their maximal oxygen uptake (VO2max) and anaerobic threshold (AT), the dancers performed a standard graded bicycle ergometer exercise test until volitional exhaustion prior to and after the supplementary training. At both these occasions, the psychomotor performance (assessed as multiple choice reaction time) and number of correct responses to audio-visual stimuli was assessed at rest and immediately after cessation of maximal intensity exercise. The supplementary low-intensity exercise training increased VO2maxand markedly shifted AT toward higher absolute workload. Immediately after completion of the graded exercise to volitional exhaustion, the ballerinas' psychomotor performance remained at the pre-exercise (resting) level. Neither the resting nor the maximal multiple choice reaction time and accuracy of responses were affected by the supplementary aerobic training. The results of this study indicate that addition of low-intensity aerobic training to regular dance practice increases aerobic capacity of ballerinas with no loss of speed and accuracy of their psychomotor reaction.

On the basis of results obtained in recent studies of foot pedal placement as well as specifications found in human factors guidelines, four different foot pedal configurations were tested for suitability in public school buses. Both simple movement time and choice reaction time measures were taken for ten female subjects on three coplanar arrangements and one configuration with a vertical separation between the accelerator and brake pedals. Results indicate significantly faster brake movement times for all three coplanar arrangements than for the arrangement with a vertical separation between the two pedals. With respect to the coplanar arrangements, brake movement time was significantly faster for the two arrangements with a horizontal separation of 12.0 cm rather than the arrangement with only 8.0 cm of separation. Therefore, it is concluded that operator performance may be significantly improved by providing a coplanar pedal arrangement with approximately 12.0 cm of horizontal separation.

Practice Trials

The current investigation examined a visual choice reaction time (CRT) task to determine its suitability for repeated measures experimentation. Fifteen Navy enlisted men served as subjects for one-, two-, and four-choice reaction time conditions. Fifty trials on each condition were administered for 15 consecutive workdays. Reaction time (RT), movement time (MT), and total time (TT) were recorded for each trial. Results indicated that across all RT conditions, intersession correlations were differentially stable by about Day 8, with reliabilities around .71. Means remained unchanged over the stable days and variances remained constant across all 15 days of the experiment for the RT measure. It was concluded that studies using RT as the dependent variable should allow for sufficient RT practice prior to data collection to ensure that the results are not contaminated by learning effects. It is recommended that at least 1000 practice trials be given prior to using an RT task to assess the effects of an environment.
