A longstanding and fundamental debate in developmental science is whether knowledge is acquired through domain-specific or domain-general mechanisms. To date, there exists no tool to determine whether experimental data support one theoretical approach or the other. In this article, we argue that the U- and N-shaped curves found in a number of…

Second-order conditioning (SOC) is the association of a neutral stimulus with another stimulus that had previously been combined with an unconditioned stimulus (US). We used classical conditioning of the proboscis extension response (PER) in honeybees ("Apis mellifera") with odors (CS) and sugar (US). Previous SOC experiments in bees were…

Event-related brain potentials were recorded while subjects listened to sentences containing a controlled infinitival complement. Subject and object control items were used, both with 2 potential antecedents in the upper clause. Half of the sentences had a gender agreement violation between the null subject of the infinitival complement and an…

This study examines interrelationships among several episodic memory tasks, particularly correlations among various attributes of memory: imagery, associative, acoustic, temporal, affective, and frequency. Undergraduates completed 28 episodic memory tests using tasks such as free recall, paired associates, classical recognition, and memory span.…

Experiment was designed to test the explanation of the developmental interaction separately for the item learning and associative learning components. (Author)

A study was designed to determine if the results of a previous investigation could be duplicated, and if so, whether the observed effect was independent of content. The results of the earlier study had indicated that shifting from one form or "code" of expression to another inhibits a student's ability to express a concept explaining a physical…

Different effects of instructional strategies on recall and comprehension of terms frequently used in formal analysis of art were examined. The study looked at a synthesis of three theoretical positions: dual-coding theory, schema theory, and elaboration theory. Two-hundred and fifty sixth-grade students were randomly assigned to three groups:…
