How Do Drivers Perceive Risks During Automated Driving Scenarios? An fNIRS Neuroimaging Study.

Objective: Using brain haemodynamic responses to measure perceived risk from traffic complexity during automated driving.

Background: Although well-established during manual driving, the effects of driver risk perception during automated driving remain unknown. The use of fNIRS in this paper for assessing drivers' states posits it could become a novel method for measuring risk perception.

Effects of sleep inertia after daytime naps vary with executive load and time of day.

The effects of executive load on working memory performance during sleep inertia after morning or afternoon naps were assessed using a mixed design with nap/wake as a between-subjects factor and morning/afternoon condition as a within-subject factor. Thirty-two healthy adults (mean 22.5 ± 3.
