VIGIL Vigilance

Application

Assesses attention over extended periods of time.
The term “vigilance" is used in psychology mainly to refer to the sustaining of attention in monotonous stimulus situations. Individuals performing certain monotonous activities do not always receive the arousal impulses that they need; this leads to mental fatigue and hence to a decline in performance efficiency. It is this situation which has given rise to the concept of being “overchallenged by understimulation”.
The ability to maintain attention or sustained alertness in stimulus-poor situations is often important in safety-related jobs; it is therefore tested in safety assessments and traffic psychological investigations. The test is also used in sports psychology and in clinical neuropsychology, because various neurological and mental disorders can affect attention.

Administration

A bright dot, set against a black background, moves along a circular track. At irregular intervals the dot makes a double jump; the respondent must react to this by pressing a button.

Test forms

S1: Standard form with circular path (based on Quatember-Maly)
S2: Standard form without circular path (based on Müggenburg)
S4: Long form without circular path (based on Müggenburg)

Scoring

The following main variables are scored:

  • Number correct: Measure of observational accuracy over the test as a whole.
  • Number incorrect: Control variable that indicates whether the respondent has understood the instructions and taken the task seriously.
  • Mean value of reaction time for correct reactions: Measure of information processing speed and motor reaction ability.
