PSYC 105 Lecture Notes - Lecture 10: Developmental Disorder, Handsfree, Speech Production
Document Summary
In 80% of crashes and 67% of near crashes, driver was inattentive in some way 3 seconds beforehand. Risk of accident 4 times higher with cell phone use: strayer and johnson (2001) Participants on cell phone missed twice as many red lights and took longer to apply the brakes. More brain power used to talk to someone on a cell phone vs. talking to someone in the car. Speech production is a big part of the mental workload. Not just about finger movements; also about hands-free mentally: central executive: boss of system to allocate resources when multitasking and focusing. Prefrontal cortex (pfc) particularly important to executive control. With damage, perseveration errors and goal neglect: practice enables people to multitask at things that were difficult at first, schneider and shiffrin (1977) Divide attention between remembering target and monitoring rapidly presented stimuli to see if the target was present. Overtime, practice increased capability to determine if the target was present.
