Three experiments examined whether the phenomena of visual search for single characters (Sternberg, 1966) generalizes to word and word-category search when target and distractor sets had varied and consistent mappings across trials. Previous results were replicated. Four principles of search are discussed within a theory of automatic/control…

A mathematical model of information acquisition is presented and empirically evaluated in comparison to evidence obtained from experimental studies of science content acquisition. Implications of the model for human information acquisition and future research are discussed in the context of the unique theoretical framework of the model. (Author/JN)

Several common errors reflecting difficulties in probabilistic reasoning are identified, relating to ambiguity, previous outcomes, sampling, unusual events, and estimating. Knowledge of these mistakes and interpretations may help mathematics teachers understand the thought processes of their students. (MNS)

This study demonstrated a reliable method of determining the attributes of prose materials on an imagery-concreteness scale, and evaluated the effects of an advance organizer and a learning passage on learning and retention when the attributes of these passages are defined on a concrete-imagery continuum.
