On estimating inter-subject variability of choice probabilities under observability constraints

Methods are presented for estimating inter-subject variability of the probability of a given event defined in terms of subject's behavior (e.g., probability of a given choice in a discrimination experiment). The constraints consist of using no more than two independent observations for each subject. Estimators are provided for assessing the inter-subject “variance” of the analyzed probabilities; also, a method is given for testing the hypothesis that the average probability is the same for two groups of subjects.

Socratic Proofs and Paraconsistency: A Case Study

This paper develops a new proof method for two propositional paraconsistent logics: the propositional part of Batens' weak paraconsistent logic CLuN and Schütte's maximally paraconsistent logic Φ_v. Proofs are de.ned as certain sequences of questions. The method is grounded in Inferential Erotetic Logic.     

Definitions need to be precise and consistent: A reply to Haslam with suggestions for the future

In his reply to our critique of research on self-humanizing, Haslam claims that we used a narrow definition of self-humanizing that ignored the evidence from the correlational research he and his colleagues have done. We disagree. First, we relied upon a definition of self-humanizing based upon comparative judgments that Haslam and colleagues have consistently used. Second, we were well aware of the correlational research he and his colleagues have done. We simply did not think, and do not think, these correlations verified the existence of self-humanizing as defined. In his reply, Haslam offered a new definition of self-humanizing that defines self-humanizing in terms of correlations between comparative judgments and ratings of how much traits reflect human nature. Although we believe this change represents some progress, numerous issues in the study of self-humanizing remain to be resolved. We offer some suggestions for future research on this important topic.     

Finite Basis Theorem for Filter-distributive Protoalgebraic Deductive Systems and Strict Universal Horn Classes

We show that a finitely generated protoalgebraic strict universal Horn class that is filter-distributive is finitely based. Equivalently, every protoalgebraic and filter-distributive multidimensional deductive system determined by a finite set of finite matrices can be presented by finitely many axioms and rules.
