Some previous studies of visual word recognition have reported an interaction between visual field and word length (measured by number of letters), such that recognition is affected more by word length for words presented in the left than for words presented in the right visual field. However, when manipulating serial position of letters in words…

Investigates why young children who cannot seriate on the standard Piagetian task do seriate when given a task that uses different materials. Explores the process by which various levels of seriation ability are achieved. Findings are consistent with information-processing analyses of development but conflict with Piagetian stage theory.…

The primacy model is presented as a new model of serial recall. This model stores order information by means of the assumption that the strength of activation of successive list items decreases across list position to form a primary gradient. The model produces accurate simulation of the effects of word length, list length, and phonological…

Memory for repeated items often improves when repetitions are separated by other items-a phenomenon called the spacing effect. In two experiments, we explored the complex interaction between study strategies, serial position, and spacing effects. When people studied several unmixed lists, they initially used mainly rote rehearsal, but some people…

Two experiments examined the ability of preschool children to reason about the numerical relations greater than and less than. Results showed that children as young as 21/2 years of age could make number-based relational judgments and compare two number pairs on the basis of a common ordering relation. (Author/JMB)

Investigated the seriation ability of two groups of four-year-old children with differing levels of language functioning. Results indicated that subjects with delayed language development demonstrated a severe delay in seriation ability, while subjects with normally developing language demonstrated seriation ability commensurate with their…

The mean and variance of the number of turning points in random permutations are evaluated. These results are applied to a test of randomness of fluctuations.

The ability of preschool children to construct and reconstruct ordered sequences was examined in a series of four experiments. Subjects were 42 children aged 3 to 5 years. The conditions under which reconstruction of an arbitrary series of events is possible are described. (Author/GO)

The relationship among the Piagetian concepts of identity, seriation, and transitivity was explored with preschool subjects. (JMB)

Studies of monolingual speakers have shown a strong association between lexical learning and short-term memory (STM) capacity, especially STM for serial order information. At the same time, studies of bilingual speakers suggest that phonological knowledge is the main factor that drives lexical learning. This study tested these two hypotheses…
