“…In this regard, Bunce and Sisa (2002) analysed the effects of age on subjective mental workload measured by the NASA-TLX during the course of a vigil and how do workload perceptions relate to performance on a vigilance task. They showed a certain interest, albeit indirect, in studying the effects of this type of characteristic on subjective estimations of mental workload when they discussed the deterioration of cognitive ability resulting from aging.…”

Título: Efectos de la carga de tarea y las capacidades cognitivas sobre el rendimiento y la carga mental subjetiva de una tarea de seguimiento. Resumen: El objetivo de esta investigación fue determinar los efectos del nivel de inteligencia general y del perfil aptitudinal de los individuos sobre el rendimiento y las evaluaciones subjetivas de carga mental de una tarea de seguimiento. A pesar de que la mayoría de los autores señalan que la carga mental depende tanto de las características de la tarea como de la capacidad de los individuos, la investigación dirigida a determinar la influencia real de los factores de diferencias individuales es muy escasa. En este estudio se recogieron medidas del rendimiento y de la carga mental subjetiva en una tarea de seguimiento con diferentes niveles de dificultad. Los resultados mostraron efectos significativos, simples y de interacción, de los factores de complejidad de la tarea tanto sobre el rendimiento como sobre la carga mental subjetiva. La aptitud espacial fue la que mostró un mayor efecto mediador, particularmente sobre la carga mental. Los sujetos con un mayor nivel aptitudinal registraron evaluaciones de carga mental más elevadas que los menos aptos, independientemente del instrumento utilizado para medir la carga mental. Finalmente, los sujetos más aptos alcanzaron niveles de rendimiento más altos que los menos aptos, especialmente en la condición de seguimiento más difícil. Palabras clave: Carga mental subjetiva; capacidades cognitivas; tarea de seguimiento; rendimiento. Abstract:The aim of this study was to determine the effects that the level of general intelligence and the aptitude profile of individuals have on performance and subjective assessments of the mental workload involved in carrying out a tracking task. Although all authors acknowledge that mental workload depends both on the characteristics of the task and the ability of individuals to perform it, little research into the real influence of these individual difference factors has been carried out. The subjects' performance and mental workload when carrying out a tracking task with different levels of difficulty were measured. Both simple effects and those relating to the interaction of the two task complexity factors were shown to have significant effects on performance and subjective mental load. Spatial aptitude was shown to have the greatest mediating effect, particularly on mental workload. Surprisingly, the subjects with the greatest ability reported higher mental workload assessments than those less able, irrespective of the instrument used to measure the workload. Finally, the subjects with greater ability achieved higher levels of performance than those less able, particularly in the more difficult tracking task.

“…Overall, the women perceived higher physical demands at work than men (Nyga˚rd et al 1997). Bunce and Sisa (2002) ascertained the differences with age in perceived workload across short vigilance tasks. They indicated that, while older participants were able to maintain the same performance level as their younger colleagues, they perceived a greater increase in the workload associated with that demand for vigilance.…”

A 16-year follow-up study of physical capacity in relation to perceived workload among ageing employees

The main purpose of this study was to ascertain musculoskeletal and cardiovascular capacity among ageing employees in relation to workload over a period of 16 years. The data were obtained by physical capacity tests and ratings of perceived exertion (RPE) during working day. The study group consisted of 89 subjects, who were all employed in the municipal branch and were on average 51.9 years old at the beginning of the follow-up period in 1981 and 67.3 years in 1997, when the most of the subjects had retired (with only two subjects still working). During the 16-year follow-up period, age-related decline in physical capacity was observed. Nevertheless the improvement in flexibility of spine and in isometric trunk muscle strength compared with the same age subjects was more common among the subjects with high workload than among the subjects with low workload. However, among the subjects with high workload, physical capacity was poorer than among the subjects with low workload, especially among the women. The results suggest the conclusion that there are differences in workers' physical capacity in relation to their perceived workload during working life. These differences remained when the subjects had retired. Interestingly, those who had high workload had lower muscle strength than those who had low workload. This may indicate that high physical workload does not have any training effect on the muscle strength of ageing workers.

The Impact of Time Efficacy on Air Traffic Controller Situation Awareness and Mental Workload

Time efficacy reflects people's perception of control time and evaluation of time management behaviors, and potentially influences situation awareness (SA) and mental workload experienced by air traffic controllers. In this study, a total of 31 air traffic controller trainees, assigned to a high or low time efficacy group, completed 2 scenarios with few or many aircraft simultaneously in the sector. The results showed that the high time efficacy group maintained better SA and experienced lower mental workload. The findings have implications for the selection, training, and work shift arrangements of air traffic controllers.Time is an essential characteristic of air traffic control (ATC) as well as the principal constraint in the air traffic controller's job, which routinely involves dividing attention among multiple sources of information and performing multiple tasks nearly simultaneously under, at times, severe time pressure. Attention and switching attention require time (Hopkin, 1995), as does performing control actions. The latter are predominantly mediated by voice communications between controllers and pilots and between controllers in different sectors. The highly redundant com-
