Traditional and Rank-Based Tests for Ordered Alternatives in a Cluster Correlated Model

Psychometrika - Methods for the analysis of one-factor randomized groups designs with ordered treatments are well established, but they do not apply in the case of more complex experiments. This...     

Is I Guaranteed to Refer?

Abstract: One claim about I , regularly made and almost universally endorsed, is that uses of the term are logically guaranteed to refer successfully (if they refer at all). The claim is only rarely formulated perspicuously or argued for. Such obscurity helps disguise the fact that those who profess to advance the claim actually turn out to support not a logical guarantee at all but merely high security through fortunate coincidence. This is not surprising. For we have no good reason to accept the claim – granted, any use of I is apt to refer successfully; but that can be explained by pragmatic features of its use. And we have some reason to reject the claim – it is notoriously difficult to see how genuine reference and guaranteed success do not exclude each other when considered as properties of the logic of any term.     

Attitudes and Attraction: Optimism and Weight as Explanations for the Similarity–Dissimilarity Asymmetry

The positive link between attitude similarity and attraction is one of the fundamental outcomes in social psychology. However, attitude dissimilarity seems to be a stronger driver of this relationship than attitude similarity. The authors review the evidence on this similarity–dissimilarity asymmetry, and discuss two explanations. One is that people generally enter into interactions with optimism, and so supposedly neutral partners are often seen as mildly positive. Another is that dissimilar attitudes carry greater weight than similar attitudes in cognitive processes. Implications of these mechanisms for wider issues in person perception and attitude structure are discussed, connecting them with more recent theories of attitudinal ambivalence and evaluative space.
