Article Synopsis
- Dual-tasking can negatively impact performance, known as the Dual-Task cost, particularly when tasks rely on the same brain regions.
- Recent advances in neurophysiological studies, including those with intracranial EEG, have helped clarify the source of this cost in humans during complex scenarios, such as responding to questions while driving.
- The study found that although neuroelectric interferences occurred in critical brain areas, participants were able to adapt their strategies to reduce these interferences without affecting their performance.
This article provides an exhaustive description of a new short computerized test to assess on a second-to-second basis the ability of individuals to « stay on task », that is, to apply selectively and repeatedly task-relevant cognitive processes. The task (Bron/Lyon Attention Stability Test, or BLAST) lasts around 1 min, and measures repeatedly the time to find a target letter in a two-by-two letter array, with an update of all letters every new trial across thirty trials. Several innovative psychometric measures of attention stability are proposed based on the instantaneous fluctuations of reaction times throughout the task, and normative data stratified over a wide range of age are provided by a large (>6000) dataset of participants aged 8 to 70.
