La carga mental constituye un tópico que reviste cada vez más importancia en ergonomia, a medida que la moderna tecnologia se ha ido introduciendo en la práctica totalidad de los entornos, imponiendo mayores demandas cognitivas a las personas encargadas de llevar a cabo las tareas que nos plantea la vida cotidiana. No existe consenso en su definiciónconcreta, ni posee una unidad de medida específica. Su evaluación se acostumbra a efectuar mediante una bateria de procedimientos que abarcan desde sus posibles generadores hasta la opini6n de las personas que realizan las tareas. La fatiga mental, provocada tanto por infra como por sobrecarga, y los posibles errores que pueden generarse, son dos de lasconsecuencias cruciales que conviene analizar, todo ello desde la perspectiva de la generación de la carga mental: el procesamiento de información. Finalmente, conviene considerar los procesos de normalización internacional de la temática que se están desarrollando.
The introduction of modern technology in almost every human environment imposes higher cognitive demands on people pegorming everyday tasks. This is why mental workload is a topic of increasing importance. There is no agreement on the definition of mental workload, nor any unit of measurement. It is usually assessed through un array of methods that focus on items ranging from its possible sources to the opinions of thepeople performing a specific task. Mental fatigue (induced by infraload as well as by overload) and the mistakes that may arise from it are two of the main consequences that should be analysed fiom the perspective of their ca~ise- that is, information processing. Finally, the paper describes the current attempts to standardize the coiacept of mental workload.
