“…We opted to use ambulatory heart-rate monitoring as our principal physiological measure, primarily because of the robustness of the ECG signal, and the existence of a large and coherent literature indicating that it is a useful indicator of anxiety and arousal (Breznitz 1967, Mansueto and Desiderato 1971, Petry and Desiderato 1978, Schnore 1959. In order to explore subjective aspects of the situation we used the Visual Analogue Scale (VAS) which has previously proved useful in investigating a range of stresses from sleep deprivation to high pressure (Herbert et al 1976, Lewis andBaddeIey 1981).…”

Inexperienced speakers were tested shortly before they presented colloquium papers at a public forum. Increases in anxiety and arousal were found using subjective and ECG measures. Performance deteriorated in digit span and verbal fluency but not in logical reasoning, tick length or the Stroop test. However, degree ofdecrement was small and rate of accumulatingdata slow, suggesting this is not an ideal situation for studying the effects of apprehension on performance, IntroductionThe question of how fear and anxiety influence performance is one ofconsiderable practical significance. Whether the fear is experienced by a soldier in battle, a victim in a natural disaster or a student in an examination, his ability to hnction efficiently is likely to be'crucial, and any decrement in cognitive performance could have significance out of all proportion to its apparent magnitude. For that reason, there has over the years been a great deal written on the influence of fear on performance. Unfortunately, however, there can be few areas in which the ratio ofobjective evidence to anecdote and speculation is so low.

“…This requires the subject to respond to 20 items using a four-point scale, and yields separate measures of trait anxiety, the subject's general tendency to be anxious, and state anxiety, his or her level of anxiety at the time of test (Spielberger et al 1970). We opted to use ambulatory heart-rate monitoring as our main physiological measure, primarily because of the robustness of the electrocardiographic (ECG) signal and the existence of a large and coherent literature indicating that it is a useful measure of anxiety and arousal (Schnore 1959, Breznitz 1967, Mansueto and Desiderato 1971.…”

Trainee parachutists were tested on two occasions during a two-day training course. The first test was always on day 1 when no jumping occurred, while the second test either occurred on the afternoun of day 1 (control group) or occurred immediately prior to entering the aircraft for their first ever jump on the afternoon of day 2 (fear group). Level of anxiety was assessed both subjectively and by ambulatory heartrate monitoring, and a range of performance tests were given. Subjects proved to be significantly more anxious in the pre-jump fear condition on both subjective and heart-rate measures. A significant decrement in performance was observed for digit span, logical reasoning test accuracy (though not speed), speed of letter search and speed of performing the visuo-spatial Manikin test. Stroop task performance was not influenced by anxiety. There was no correlation between rated jump performance and either anxiety or personality as .measured by the Eysenck Personality Questionnaire.

“…In fact, a person can be identified by his pattern, and these patterns are stable over long periods of time. Thc patterns arc also maintained over different stressors, although thc relative difference changes (Lacey 1950and 1958, Lewinshon 1956, Schnore 1959. Because of the patterning phenomenon, one variable is not adequate for evaluating an individual's strain.…”

A group of twenty volunteers from difficult production jobs was used to evaluate the hypotheses that (1) the physiological strain resulting from production floor stress will be high, (2) production floor strain can be predicted from apparatus tests and (3) production floor strain will adversely affect performance. Each subjoct had his heart rate and respiration rato measured as he performed a sot of apparatus tests in a laboratory and as he performed his job on the production floor.The psychological stress and the resulting physiological strain were found to be low for experienced production workers. The apparatus test failed to predict production floor strain because of the discrepancy between tho stress levels in the laboratory and on the production floor. The low stress levels on the production floor made it difficult to evaluate the effect of stress on performance, however, there was evidence that stress does affect performance.
