title: [Changes in psychophysical parameters in relation to computer screen control work sites].
abstract: Exceptionally high demands on the psychonervous system of those engaged in certain regulatory capacities at the fluorescent screen are the order of the day. In such work, reliability of performance depends on the state of activation of the ions. Findings from the simultaneous measurement of critical fusion frequency and heartbeat frequency can be used to map out the state of activation of the ions. Optimum performance may be maintained at work for a period of up to five hours. After five hours under especially exacting working conditions, flicker frequency and heartbeat frequency were found to go into opposing phases.
