The grouping of list items is known to improve serial memory accuracy and constrain the nature of temporal errors. A recent study (M. T. Maybery, F. B. R. Parmentier, & D. M. Jones, 2002) showed that grouping results in a temporal organization of the participants' responses that mimics the list structure but not the timing of its presentation.…

Results showed that naming latency, for both letters and words, is sensitive to the number of items in the preceding list and also to the serial location of the probe item in the list. (Author)

Results indicate that Ss expectancy for a given test stimulus probability, has its effect on the encoding or decision stage of the memory-scanning process. (Authors)

Seventy two first, second and third grade boys and girls were administered seriation problems involving different combinations of shape and color variation. Success rates and latency scores were influenced by shape variation, but not by color variation or grade level. (BD)
