Unlike previous studies, the present experiments simultaneously differentiated the stimulus events along more than one (binary) dimension. (Authors)

A method for introducing ideas of probability theory is presented. The method is illustrated by solving a coin tossing" problem. (FL)

Kahneman and Tversky's critique of Cohen's position on adults' probability reasoning is not valid. If they think Baconian logic is normatively unsound, the onus is on them to explain why. It is valid and useful because nature itself is full of causal processes. (Author/RD)

Brennan's B statistic is a generalized upper-lower discrimination index which was first published in 1972: Peirce earlier introduced a statistic on the relation between a predictor and an outcome which has the same structure as Brennan's B. (Author/CP)

Six-year-olds, 10-year-olds, and 18-year-olds were studied in a probability learning experiment using a procedure analagous to that used in animal experiments. It was predicted that children, like rats, would choose higher probability alternatives more often with a noncorrection than a correction reinforcement procedure. (Author/DB)

The discrepancies in the power of voters in the various states is examined by computing the probability that an individual vote will be critical in an election. (MP)

Discussion of text compression focuses on a method to reduce the amount of storage needed to represent a Markov model with an extended alphabet, by applying a clustering scheme that brings together similar states. Highlights include probability vectors; algorithms; implementation details; and experimental data with natural languages. (Author/LRW)

Three counterexamples demonstrate that the Dutch Identity conjecture of P. Holland about examinee ability (1990) does not hold in general. The counterexamples suggest that only under strong assumptions can it be true that the limits of log-manifest probabilities are quadratic. Three propositions giving such strong conditions are given.
