title: Relationship between perceptual style and ability to reproduce a standard work task.
abstract: The present study examined the relationship between perceptual style and perception of physical effort. Perceptual style of 10 men and 10 women was assessed by the rod-and-frame apparatus. Perception of physical effort was defined as the difference in heart-rate responses between a standard work task and the subject's self-selected task. Heart-rate response on the pre-selected standard work task on a cycle ergometer (600 kpm.min.-1) was extremely variable, ranging from 111 to 188 beats per minute (M = 153 +/- 23.5). However, average error between heart rate during the standard work task and the subjects' self-adjusted workload was extremely low (range 0 to 18 beats per minute; M = 5.4 +/- 5.5 beats per minute). Pearson correlation of .78 showed a moderate relationship between heart rate and rating of perceived effort, but was nonsignificant (-.12) between perceptual style and perception of physical effort. The data confirm the absence of a significant relationship between perceptual style (i.e., field dependence-independence) and ability to reproduce a standard work task. In addition, these results suggest that there has been possible bias in studies of relationships between heart rate and rating of perceived effort or workload and rating of perceived effort during incremental testing.
