Investigates good and poor readers' ability to answer text-based inference and paraphrase questions after reading two narrative stories and two expository passages. Finds that expository passages are significantly more difficult for children to understand than narrative stories, and that good readers read texts faster than poor readers. (MM)

Sixty undergraduate college students took part in two experiments designed to test the hypothesis that the involvement of inference in remembering leads to overconfidence. Discusses the response-independence model, which is appropriate to retrieval, and the response-dependence model, which applies to inference. (DR)

Data are reviewed that suggest that there is no need to invoke a multiple-model theory of reasoning to explain the difficulty people encounter deriving valid conclusions to certain inference problems using doubly quantified sentences. Implications for theories of how people understand multiply quantified sentences are discussed. (SLD)

Presents a fully Bayesian analysis for the Probability Matrix Decomposition (PMD) model using the Gibbs sampler. Identifies the advantages of this approach and illustrates the approach by applying the PMD model to opinions of respondents from different countries concerning the possibility of contracting AIDS in a specific situation. (SLD)

The current experiment investigated the effect of differential training histories on responses to a 5-term linear chain of nonsense syllables (described here with sequential, alphabetical characters; A [is less than] B [is less than] C [is less than] D [is less than] E) across unreinforced probe trials. Participants' responses to nonarbitrary…

The assumptions underlying item response theory (IRT) models may be expressed as a set of equality and inequality constraints on the parameters of a latent class model. It is well known that the same assumptions imply that the parameters of the manifest distribution have to satisfy a more complicated set of inequality constraints which, however,…

In this note, a coin tossing experiment which leads to three discrete distributions is discussed.

The commentaries include a wealth of insightful and interesting observations and suggestions, and I appreciate each author taking the time to comment on my efforts. In responding to their suggestions, I am inclined to develop a few general points raised in the commentaries a bit further.

When Tarzan asks Jane "Do you like my friends?" and Jane answers "Some of them," her underinformative reply implicates "Not all of them." This "scalar inference" arises when a less-than-maximally informative utterance implies the denial of a more informative proposition. Default Inference accounts (e.g.,…

D. Trafimow presented an analysis of null hypothesis significance testing (NHST) using Bayes's theorem. Among other points, he concluded that NHST is logically invalid, but that logically valid Bayesian analyses are often not possible. The latter conclusion reflects a fundamental misunderstanding of the nature of Bayesian inference. This view…

This paper comments on the response offered by Trafimow on Lee and Wagenmakers comments on Trafimow's original article. It seems our comment should have made it clear that the objective Bayesian approach we advocate views probabilities neither as relative frequencies nor as belief states, but as degrees of plausibility assigned to propositions in…

This paper comments on the articles by Cheng and by Novick and Cheng. It has been claimed that the power PC theory reconciles regularity and power theories of causal judgment by showing how contingency information is used for inferences about unobservable causal powers. Under the causal powers theory causal relations are understood as generative…

The move toward online course facilitation in tertiary education has the intent of providing education at any time in any place to any person. However, the advent of blended learning and e-learning innovations has ostracised, marginalised or ignored those who cannot afford or who are unable to access the latest hardware and software to take…

This article reports on an empirical study that tests a fourth-order factor model of strategic competence through the use of structural equation modeling (SEM). The study examines the hierarchical relationship of strategic competence to (a) strategic knowledge of cognitive and metacognitive strategy use in general (i.e., trait) and (b) strategic…

The purpose of the study described in this paper was to identify those factors which affect Year 9 students at Sha Tin College, Hong Kong, as they make option choices at the end of Key Stage 3 (Year 9: age 14). The main focus of the investigation was how these factors influence the selection or rejection of the four subjects offered under the…
