Degree Of Similarity

Multidimensional analysis of similarity data was applied to the domain of a spoken vowel. Thirty-two male speakers provided samples of the vowel [æ]. Judgments of degree of similarity between each pair of vowels were obtained from 100 observers. The similarity judgments provided estimates of psychological distances between the vowels. The distances were used to construct an auditory space, Euclidean in nature, for the vowel samples. Dimensionality of the space was appropriate to account for the distances between vowels. Acoustic data were employed to identify the dimensions. The dimensions related well to frequency and amplitude properties of first, second and third formants, and good predictions as to locations of the vowels in space could be made from the acoustic data. The multidimensional scaling method shows promise as a method for structuring auditory space and for understanding processes of vowel perceptions.

Contract Formation

Abstract This article explores some behavioral findings that are relevant to three areas of contract: formation, performance, and remedies. I compare the rational choice theory analysis of various aspects of contract law with how behavioral findings lead to a change in our understanding of that area of law. A penultimate section considers several criticisms of behavioral economics. A concluding section calls for altering some settled understandings of contract law to accommodate behavioral results and for further research about some still uncertain aspects of contracting.
