Regression artifacts are a source of mistaken causal inference in inferences based on time-series data and from longitudinal studies. These artifacts are illustrated, and it is noted that their magnitude is computable (and distinguishable from genuine effects) if the autocorrelation patterns for various lags is known. (SLD)

Differential item functioning (DIF) assessment procedures for items with more than two ordered score categories, referred to as polytomous items, were evaluated. Three descriptive statistics (standardized mean difference and two procedures based on the SIBTEST computer program) and five inferential procedures were used. Conditions under which the…

Derived a confidence interval for a ratio of correlated mean absolute deviations. Simulation results show that it performs well in small sample sizes across realistically nonnormal distributions and that it is almost as powerful as the most powerful test examined by R. Wilcox (1990). (SLD)

Explores posterior analysis in estimating factor score in a confirmatory factor analysis model with polytomous, censored or truncated data, and studies the accuracy of Bayesian estimates through simulation. Results support these Bayesian estimates for statistical inference. (SLD)

Presents a model of information retrieval based on plausible inference which suggests that techniques should be found for combining multiple search strategies into an overall assessment of a document's relevance. The results of experiments designed to test this approach using a simple spreading activation search are discussed. (21 references) (CLB)

Two experiments demonstrated that by the age of four years, children can use the difference between an object's initial and final state to work out what happens to an object when it changes. In contrast, three-year-old children have difficulty in using the difference between initial and final states to make a causal inference. (RH)

Describes class activities designed to teach inference skill using combined lists. (RS)

Two studies investigated the attribution of action to beliefs and desires in 15 adults and 45 children. Children and adults shared a similar construal of human action in terms of beliefs, desires, and false beliefs. (RJC)

Theoretical nonparametric conditions under which evidence from salary studies using observed merit measures can provide a basis for inferences of fairness are discussed. Latent variable models as parametric special cases of the general conditions presented are illustrated with real salary data. Implications for empirical studies of salary equity…

Two studies explored preschool children's beliefs about the relationship between perceptually based similarity among things and their predicted behaviors by focusing on form-function correspondences. Perceptual similarity, if motivated by intuitive beliefs about correspondences between form and function was found to be sufficient basis for…

Criticizes "The Bell Curve" for its lack of understanding of the philosophical nature of intelligence (and mind). Points out that various philosophical attempts to analyze the concept of intelligence are routinely ignored by empirical workers in the field of IQ testing because such philosophical work makes obvious the lack of connection…

Investigates whether individual differences in working-memory (WM) capacity are related to the ways readers use inferences to facilitate text comprehension. Finds several differences between low-memory-span and high-memory-span readers. Notes that readers with adequate WM capacity can keep interpretations open ended and await more information from…

First, second, and fourth graders listened to stories containing an inconsistent goal and outcome. Children provided a causal inference for the inconsistency, and attributed the inference to themselves or the story. Children's attributions were related to whether the story contained causal information linking the inconsistent events. (BC)

Determinants of similarity-based access to memory and determinants of subjective soundness and similarity of a match were studied in 4 experiments involving 225 undergraduates. Results indicate dissociation between similarity governing access to long-term memory and that used in present matches. A model is proposed. (SLD)

Examined whether developmental differences exist in availability of inferences during listening comprehension. Presented child and adult subjects with consistent and inconsistent passages to determine outcome of expected and unexpected messages on memory. Found that children were more likely than adults to retain incorrect information in active…
