A formal analysis of stressor and stress‐proneness effects on simple information processing

“…Millar, 1979). Second, potential stressor effects were enhanced by keeping the stressor unpredictable and uncontrollable (Cohen et al, 1986;Finkelman & Glass, 1970; Keinan, 1987;Smith, 1989). Finally, the procedures were designed to accommodate certain additional factors, including ethical considerations, and fidelity of performance data.…”

Commuting and well-being

“…Research on how stressors (environmental demands) affect perception and information processing during 26 tasks, including driving, is not new (Brown, 1962, Brown, Tickner, Simmonds, 1966Moscowitz, 1973;Finkelman & Glass, 1970;Plutchik, 1959). Given that excess stress and strain can hinder driving performance and increase accident likelihood during commute, the study of stressors in the roadway environment is obviously important.…”

The Effects of Noise on Performance

“…Noise causes the filtering of some stimuli in favor of others, usually those proceeding from dominant sources (as, for example, in the experiments of Hockey, 1970a and b;and Finkleman and Glass, 1970).…”

“…In another experiment involving dual tasks, Finkleman and Glass (1970) presented subjects with broadband noise at 80 dB(A) in predictable and unpredictable intermittency patterns.…”
