6.3. MONOTONY 

6.3.1. DEFINITIONS 

 

The alertness level can be greatly influenced both by the environment and by the activity of the subject himself.
The environment and the type of task determine the degree of monotony of the situation as it can be defined as "the characteristics of a task in which the sensorial stimulations remain almost constant and extremely repetitive". In fact, there are two concepts in the notion of monotony:
. the state of monotony,

. the monotonous nature of the task.

The state of monotony corresponds both to a subjective feeling and to physiological and psychological manifestations.
The subjective feeling manifests itself as boredom, as disinterest in the work to be done and as a feeling of drowsiness.
