The present experiments examined perceptual specificity effects using a rereading paradigm. Eye movements were monitored while participants read the same target word twice, in two different low-constraint sentence frames. The congruency of perceptual processing was manipulated by either presenting the target word in the same distortion typography…

The hypothesis that performance on implicit learning tasks is unrelated to psychometric intelligence was examined in a sample of 605 German pupils. Performance in artificial grammar learning, process control, and serial learning did not correlate with various measures of intelligence when participants were given standard implicit instructions.…

A theory of practice in high-proficiency skills such as speech production is proposed, involving activation of a hierarchy of nodes in serial order within an output system of behavior. Increased flexibility with practice, response mechanism transfer in skills, motor equivalence, automaticity, and speed-accuracy trade-off are discussed. (Author/CM)

An associative model of serial learning is described based on the assumption that the effective stimulus for a serial-list item is generated by adaptation-level coding of the item's ordinal position. How the model can generate predictions of aspects of serial-learning data is illustrated. (SLD)

A system of precategorized acoustic storage has accounted for the recency effect obtained in the immediate serial recall of sequences of digits, consonants, or syllables. Four experiments in recall of word sequences investigated fit to this model. A system of postcategorical lexical storage was concluded to explain the results. (Author/RD)

Ratcliff's theory of memory retrieval which posits parallel processing and Sternberg's serial processing explanation of memory scanning are reviewed and contrasted. Discrepancy between the two theories may arise because they focus on different aspects of the data. If scanning without comparisons takes place, the two views may be reconciled.…

Investigates the abilities of 36 fifth graders and 30 ninth graders who were selected from 11 schools in Thailand to solve problems involving seven of Piaget's logical operations. These operations are classification, seriation, logical multiplication, compensation, proportional thinking, probability, and correlational thinking. (HM)
