Document Summary

There is research suggesting that exercise increases cognitive ability. Today is the last class for midterm material. Information processing: finished talking about age and information processing in sports. Response selection stage: once stimulus is identified, the appropriate action must be selected, e. g. to brake or swerve to avoid a parked car. Factors influencing response selection: number of stimulus response alternatives, stimulus compatibility (spatial compatibility) Increasing the number of alternatives relevant to a response increases the time required to process and select an appropriate response: experiment one, there is a blue and yellow light. Response selection becomes more difficult: as you dou(cid:271)le the (cid:374)u(cid:373)(cid:271)er of sti(cid:373)ulus", rea(cid:272)tio(cid:374) ti(cid:373)e will i(cid:374)(cid:272)rease (cid:271)y a(cid:271)out. Reaction time increased by 150ms every time the r-r alternatives doubled. Thus relationship between choice rt and the logarithm of the sr (stimulus response) alternatives is linear. So there is a log/linear relationship that allows someone to predict reaction time.
