Nonmetric scaling of line lengths using latencies, similarity, and same-different judgments

摘要: An experiment investigating the relation between various ways of deriving psychophysical functions for line length is reported. A two-phase computer-controlled in which stimuli were pairs lines was performed. In first phase, pair presented several seconds and S required to make a category judgment similarity lines. second very brief period time decided whether same or different lengths. Three sets data analyzed: (1) judgments, (2) proportion correct (3) latency judgments. individual differences analysis indicated that there data. This not applicable Nonmetric scaling revealed based on all three essentially identical
