PSYA01H3 Lecture Notes - Lecture 12: Detection Theory, Absolute Threshold, Response Bias
Document Summary
Lec 12 : sensation and perception: subliminal perception. How we take input from the world. Weber flashback: jnd just noticeable differences . Difference vs. absolute thresholds: threshold holds an opening (to pass, absolute threshold between us not being able to detect that it exists and then being able to detect it. Distinct trials that would either have a stimulus or not say no when no stimulus correct negative. Yes when stimulus is present hit stimulus presented and say no miss. No stimulus but say yes false alarm. Bias can still have an affect [effects both hits and false. Sdt : the logic, step 1 cannot take bias away from person. Manipulate so that the response bias varies. Organize each level of manipulation under subjects (initiate the bias)
