Responses to infrequent signals during repetitive work
thesis
posted on 2018-09-20, 08:39 authored by Oonagh HartnettEight women were employed on repetitive work. Records were made
of their rate of production and its variability under different conditions,
e.g. times of day, days of week, with and without rest breaks. The length
of hand reaction times, in response to rare signals involving an interruption
of the work cycle, were measured. Observations were made to see,
whether the signal external to the work cycle or whether the next step
required within that cycle, evoked the first response depending upon the
point of injection of the signal.
The results suggest that the capacity, to interrupt the work cycle
in response to the rare signal, depends upon its point of injection into
the work cycle. A formula has been evolved which expresses a significant
relationship between percentage of cycles broken or interrupted and ‘residual movement times’, i.e. the time between the point of injection
of the rare signal and the normal completion of the cycle movement.
The results also suggest that reaction times and production do vary
under the different conditions.
