Document Summary
Like turning light on is very compatible between stimulus and response (switch up = light on) Dancer turning is an ambiguous stimulus = she could be turning either way. More ambiguous it is the harder it is to respond appropriately to it. Because it slows down processing and could create errors. Left stimulus paired with right response yields longer rt cause they aren"t compatible. Is this because your mapping l stim with l hand or are you mapping l side with r side. You get a faster rt (because associated r stim with r side) proving that its not the fact that it"s the the side that matters not which hand your using. Stroop effect its hard cause stimulus doesn"t match response. Def: when an irrevelant stimulus feature has an effect due to automatic activation of word response code. Because both the word and colour compete for processing time, response is slowed (incompatible)
