Effects of task feedback and stringency of external pacing on mental load and work performance∗

Abstract: 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 … Show more

“…Workload is not only a function of task load, but also a function of organizational and environmental factors (Bi & Salvendy, 1994). Empiric evidence exists that as uncertainty decreases, workload is reduced (Knight & Salvendy, 1981;Tummers, Landeweerd, & Van Merode, 2002b). Complexity of care may call for more diagnostic and therapeutic procedures so that nurses are involved in more work diversity (Groen, 1995).…”

“…En el modelo de González (2004) la carga vendría determinada básicamente por la carga de tarea, las condiciones ambientales y las condiciones organizativas (las técnicas subjetivas y las medidas de exigencia utilizadas en esta tesis incluyen todos estos aspectos). La carga de tarea está, a su vez, definida por la configuración de la tarea respecto a una serie de dimensiones: la exigencia temporal de la tarea, su complejidad, su grado de ambigüedad y los criterios de ejecución (Knight y Salvendy, 1981;Rouse, 1985;Hart y Staveland, 1988;Meshkati, 1988;Reid y Nygren, 1988;Sheridan, 1988;Moray y otros, 1991;Bi y Salvendy, 1994;Wickens, Gordon y Liu, 1998).…”

“…y las condiciones organizativas (estilo de supervisión, etc.). La carga de tarea viene definida a su vez por la configuración de la tarea según una serie de dimensiones, sobre las que existe un consenso generalizado acerca de su importancia como determinantes de la carga mental: la exigencia temporal de la tarea, su complejidad, su grado de ambigüedad, los criterios de ejecución y la exigencia física (Knight y Salvendy, 1981;Rouse, 1985;Hart y Staveland, 1988;Meshkati, 1988;Reid y Nygren, 1988;Sheridan, 1988;Moray y otros, 1991;Bi y Salvendy, 1994;Wickens, Gordon y Liu, 1998, Rubioy otros, 2006a) (figura 3.24).…”
