74 views10 pages

Document Summary

Learning = acquisition of skill : power law. More trials less time to complete the task: cognitive, associative (association connection), autonomous, signs of learning. Limited capacity, s-a characteristic, rt, limiting principle. Information processing model: selective attention, perception, decision, effector, feedback, action. Sdt (signal detection theory: un-paced task, perceptual sensitivity (d") I. e. no confusion less errors: expectation / rewards & penalties ( ) Correct negative, fa (type i error), miss (type ii error), hit. More miss, less false alarm admission"s office. Drt (discriminatory reaction time: paced task, crossman"s confusion function. Drt = a + b [1 / (log 2 x1 log 2 x2) bits] Less difference between two stimuli longer reaction time. Crt (choice reaction time: hick-hyman law. Crt = a + b log2 n bits. Drt (discriminatory reaction time: paced task. If given sufficient time to respond. In practical situations both kinds of analysis (sdt & drt) may be appropriate: sdt (signal detection theory, drt (discriminatory reaction time)
