What is divided attention and what does this test measure?
Divided attention is the cognitive ability to allocate mental resources across two or more independent information channels concurrently. This test measures your ability to simultaneously track moving visuospatial targets while categorizing a continuous numerical stream, quantifying cross-channel accuracy, response latency, and dual-task degradation under time pressure.
What is the Psychological Refractory Period (PRP)?
The Psychological Refractory Period (Pashler, 1994) is the brief delay in processing that occurs when a second stimulus is presented shortly after a first. Because executive central bottleneck resources cannot be fully shared across two demanding decision stages, response time on the secondary task slows down significantly.
What does Wickens' Multiple Resources Theory tell us about divided attention?
Christopher Wickens (2002) demonstrated that humans can divide attention far more effectively when concurrent tasks use distinct sensory modalities and processing codes. By pairing a visual-spatial target task with an auditory or verbal classification task, interference is mitigated compared to two identical visual tasks.
Can you actually improve divided attention or multitasking?
Possibly. Spelke, Hirst & Neisser (1976) reported that two participants trained over many weeks could perform two tasks together with far less interference. That was a small laboratory study, so treat it as evidence that practice can reduce dual-task cost, not a guarantee for this drill.
How does this test differ from general multitasking in daily life?
Unlike casual workplace multitasking which often involves rapid serial task-switching rather than true concurrent processing, this drill requires real-time simultaneous sensory gating — keeping visual focal tracking engaged while continuously evaluating numeric stream values.
What is considered an elite score on this test?
Scores above 15,000 points with an overall accuracy above 92% mark practice stage 5, reflecting strong prefrontal executive control and high working memory throughput.
How does fatigue affect divided attention?
Sleep deprivation and mental fatigue disproportionately degrade central executive bandwidth, widening the Psychological Refractory Period and causing tunneling (visual neglect of secondary streams).
Does monitor refresh rate influence dual-task scores?
A high-refresh display (144Hz or more) shows motion in smaller steps than a 60Hz one, and display timing affects what a browser test can resolve (Woods et al., 2015). It is not required, and whether it changes your score is something to check by comparing your own runs on one setup.
What is the recommended daily training routine?
A 10-to-15 minute daily session provides optimal neuroplastic stimulus without inducing central fatigue.
