Document Summary

Reaction time is affected by : stimulus factors stimulus predictability: Rt = a + b (log2n) (hick"s law, 1952) where n is number of. Example: driving, rt, stopping distance & the added effect of texting: reaction time consumes a lot of time of the stopping distance stimulus affects response. Texting - whilst driving - significantly delays your rt, & thus adds to your stopping distance. ~160ms of each other: also indicates serial information processing. Two: serial processing preceded by parallel processing of information from sensory (afferent) systems, parallel: do stage 1 by analysing all information coming in at the same time saves time, likely to transfer into serial in movement planning. Three: cascade processing (possible but not necessarily reported, cascade: prepare movement (& wait for signal) & prevent decision making, also saves time; make things overlap, overlap in stages (e. g. response plan begins, even though still gathering information)
