“…240 sand 15 s conditions, respectively), F(l, 15)=4,98, p <0·05. This replicated Manenica's (1977) and Salvendy and Humphrey's (1979) Of more interest, however, in present results is the appearance of a statistically significant interaction between Pacing and Feedback conditions, F(3,45)=2'99, p < 0·05. As the table shows, sinus arrhythmia was not lower in self-pacing if both time and cycle feedback were provided.…”

“…The extent to which decisions appropriate for physically demanding tasks also apply to cognitively demanding tasks is unclear. Manenica (1977) and Salvendy and Humphreys (1979) have reported the surprising finding of lower sinus arrhythmia in self-paced tasks than in externally-paced tasks even when energy expenditures were minimized and production output was equated. Sinus arrhythmia has been found to vary inversely with cognitive workload.…”

Sixteen subjects were used to study the effectsof two levelsof pacing constraint and four performance feedbacks on the performance and mental load associated with a manual task. The following main conclusions emerged: (I) performance feedback reduces the mental load of the task only when the pacing constraint is low and (2) feedback improves task performance when the pacing constraint is low since operators are able to meet work requirements more closely. Feedback, however, does not improve the performance or reduce the mental load of a highly paced task.

“…For example. Manenica (1977) has suggested that the lower sinus arrhythmia in self-paced as compared to machine-paced work results from an "internal pacing mechanism" intrinsic to self-paced work. which effectively increases the mental load and hence the mental effort.…”

This article presents an overview of the topic of occupational stress. Although its framework is somewhat conceptual, the article is intended to alert researchers to the practical considerations relevant to this topic. The authors attempt to arrive at a workable definition of stress, and then proceed to review the literature in this area, focusing on the measurement, sources, and management of stress, as well as the relationship between stress and coronary heart disease. Concepts related to stress (mental load, fatigue, and arousal) are defined and differentiated. Throughout, the effects of individual attributes are emphasized, as are the implications of investigating stress in the laboratory as opposed to the work environment.

“…Komaki et al (1980), obviously responding to the continuing debate regarding the relative effectiveness of feedback versus goal setting (Locke 1980), con cluded that safety training was not sufficient to substantially improve and maintain perfonnance even though desired practices were objectively defined and examples were tailored to specific job situations. This research suggests that feedback might be used as a means of reducing cognitive load, and thus work-induced physiolog ical stress, in self-paced tasks (Manenica 1977. Knight & Salvendy (1981) and Matsui et al (1982) examined the moderating effects of task and person variables on feedback effectiveness, respectively.…”
