Detailed Description+

Measures vigilance and sustained attention, subfunctions of attention.

Eight test forms are available, which make it possible to measure vigilance or sustained attention with different stimulus modes (visual or auditory) or test durations (30 or 15 min). Vigilance and sustained attention differ in the frequency of the relevant stimuli.

Attention performances are important for the successful handling of the tasks that the individual encounters in daily life. They are not independent of other skills but are a constituent of many processes of perception, memory, planning and acting, spatial orientation and problem-solving. Attention functions are thus basic skills that are required in almost every practical or intellectual activity. Many neurological and psychological disorders and diseases have an adverse effect on different aspects of attention performance. Therefore, the model and guideline compliant (GNP) WAFV test is primarily used in clinical neuropsychological investigations. It is also also used for personnel selection (especially in the field of manufacturing & safety assessments) and for traffic psychological investigations.
