PSY387H5 Lecture 3: Tutorial 3
Document Summary
First experiment: melodies/tunes were familiar and pitch shifted in the same direction (either up or down, condition: one day heard the pitch shifted 2 semi-tones, and the other day it was shifted 1 semi- tone. Results: showed more correct distinctions for the 2 semi-tones. Second experiment: used songs that they were not familiar with, 50% less correct when they didn"t know the tune (it was prob just chance since they were guessing if they didn"t know the song). What was chance performance on this task: 50-50 exactly, if we see number greater, then we can say that people do have pitch memory. If the numbers are lower, then we can say people do not have pitch memory. Why were the original sound files pitch shifted then pitch shifted back: in case of digital issues. How did the design ensure that repeatedly giving the same response would lead to 50% correct: counterbalance.
