摘要: A threshold parameter has been introduced into the power law in two different ways, one involving, translation on stimulus axis (the Ф-Law) and second involving response Ψ-Law). In this study laws were compared using data from 6 Ss making magnitude estimation judgments of brightness. Although prevalent view appears to favor Ф -Lau, clearly dictate a choice Ψ-Law over $-Law for
