Results of two studies investigating preschool children's ability to infer another person's knowledge or ignorance on the basis of that person's recent perceptual experience suggest that understanding of perception as a source of knowledge is present by the age of three years. (RH)

Assessed age differences in making inferences from prose. Older adults correctly answered mean of 10 questions related to implicit information and 8 related to explicit information. Young adults answered mean of 7 implicit and 12 explicit information questions. In spite of poorer recall of factual details, older subjects made inferences to greater…

Two experiments with 11 college students demonstrate the influence of their prior visual adaptation to motion on the imagined speed of an imaginary moving object. Results suggest that imagined motion and real vision may engage common neural mechanisms without being functionally equivalent. (SLD)

Hierarchical models are extremely promising tools for data analysis, but it is important not to lessen hard thinking about data and iterative model checking when fitting hierarchical models. More and better software, methods to assure proper calibration, and materials in support of hierarchical model use are all needed. (SLD)

A psychological theory of the logical particle "if" is presented that consists of a lexical entry, a set of pragmatic comprehension processes, and a reasoning program. The core of the theory is two inference schemas originally proposed by logicians. The theory can account for available data from children and adults. (SLD)

The distinction between remembering text information and applying the acquired knowledge (making inferences) was studied with a dissociation paradigm, using 110 undergraduates who performed verification and recognition tasks. The same variables did not affect performance on the two tasks. Text organization affected recognition but not verification…

Cross-lagged methodology (CLM), which is virtually ignored by psychological researchers, is suggested for studies of causal relations in which controlled experimentation is unfeasible. The longitudinal facet in the design of CLM is highlighted. Advantages and limitations of the CLM are described. (SLD)

The notion that inferences contributing to coherence of a text representation are made during reading is examined. It is demonstrated that this idea is an overgeneralization and that one must distinguish between relations internal to the structure of the representation and relations that involve references to the world. (27 references) (Author/LB)

The EA:es index (part of the Comprehensive Rorschach System) is discussed, demonstrating how conceptual difficulties and abstract jargon can result in misleading and contradictory inferences. The comments of J. E. Exner, Jr., and the response of J. H. Kleiger concern the importance of theory in Rorschach interpretation. (SLD)

Suggests that in learning and development, the process of comparison can act as a bridge between similarity-based and rule-based processing. A structure-sensitive comparison process, triggered by experiential or symbolic juxtapositions can: (1) facilitate understanding of structural commonalities and the abstraction of rules; and (2) facilitate…

A set of conditions is presented for the validity of inference for Item Response Theory (IRT) models applied to data collected from examinations that allow students to choose a subset of items. Common low-dimensional IRT models estimated by standard methods do not resolve the difficult problems posed by choice-based data. (SLD)

Proposes guidelines for revising the American Psychological Association (APA) publication manual or other APA materials to clarify the application of statistics in research reports. The guidelines are intended to induce authors and editors to recognize the thoughtless application of statistical methods. Contains 54 references. (SLD)

Proposes a probability heuristic model for syllogistic reasoning and confirms the rationality of this heuristic by an analysis of the probabilistic validity of syllogistic reasoning that treats logical inference as a limiting case of probabilistic inference. Meta-analysis and two experiments involving 40 adult participants and using generalized…

Seven studies involving 256 undergraduates examined how people represent, access, and make inferences about the real-world category domain, foods. Results give a detailed picture of the use of cross-classification in a complex domain. (SLD)

Responds to Biskin's comments (this issue) on the significance test controversy. Highlights areas of agreement (importance of replication evidence, importance of effect sizes) and disagreement (influence of sample size, evaluation of populations vs. samples, significance of Carver's article). Includes further recommendations for reporting research…
