Document Summary

Motor, cognitive, perceptual: learning = acquisition of skill . Limited capacity, s-a characteristic, rt, limiting principle: information processing model. Selective attention, perception, decision, effector, feedback, action: sdt (signal detection theory) I. e. no confusion i. e. less errors. Correct negative, fa (type i error), miss (type ii error), hit. Shift to left: lax, less miss, more false alarm medicine. Shift to right: strict, more miss, less false alarm admission"s office, drt (discriminatory reaction time) Drt = a + b [1 / (log 2 x1 log 2 x2) bits: crt (choice reaction time) Crt = a + b log2 n bits: n = s-r choices. Perception mechanism (stimulus identification: selective attention. Sensory stage where we decide if a stimulus is present and. How to solve the problem of deciding between two categories when they are not detectable. Concerned with the accuracy of responses: not under time pressure but < 100% accuracy.
