Document Summary
Movement preparation: what phases are involved and how do they relate, intention, preparation, initiation, termination. Task and situation characteristics: number of response choices, increase in choices => increase in rt, hick"s law (hick-hyman law is same, index of difficulty of hick"s law: rt = b log2 (n+1, n = number of choices. Task and situation characteristics: predictability of the correct response choice, rt decreases if the correct response choice becomes more predictable, precuing paradigm, precue: advance information about an upcoming event that needs a response. Let"s you know what kind of response is needed: attention, probability of the precue correctness, rt becomes, faster if the precue correctness probability is higher than the probabilities equally possible choices (50% - 2 choices: move to right 80% (faster), move to the left 20% (slower: cost-benefit trade-off for bias to the anticipated required response. Cost if information is incorrect. (if right is incorrect then it will be slower getting to the left)
