Test ability to multi-task

The Divided Attention task measures a person’s ability to “multi-task” or concentrate on two or more things simultaneously. Almost every job requires this ability to some extent.

Test vigilance

The Selective Attention or Vigilance task measures a person’s ability to maintain concentration on a task for a sustained period of time.

Test distractibility

The Selective Attention or Filtering task measures an individual’s ability to focus on important information and ignore irrelevant distractions. Together with the Vigilance Task, Filtering provides an indication of the test subject’s selective attention, the ability to sustain concentration and ignore distractions – a characteristic important to job performance in a wide variety of jobs.

Test reaction time

The Perceptual Reaction Time task measures one of the most basic cognitive processes: perceptual reaction time, or the speed at which a person recognises and responds to a stimulus.
