Abstract

The performance of certain hand activities is influenced by reduced ambient temperatures. Seventy trained subjects completed an assembly task at air temperatures of 1·7°C, 12·8°C and 23·9°C, and their completion times were recorded.

Based on the experimental results, an empirical relationship between the cumulative probability of completion, the air temperature, and the performance times was developed. The empirical distribution is equivalent to the reliability function of the assembly task. Results indicated no difference between performance at 12·8°C and 23·9°C but a reduction in performance at 1·7°C. The model was compared with experimental trials of a similar task.
