Study attempted to specify two complementary aspects of children's inferential size judgments within the context of Piaget's theory. (Authors)

Data suggests that perceptual processing in the language-appropriate direction is an established skill by the time a child finishes second grade. (Author)

Two strings of letters were presented. Subjects were instructed to indicate whether the second string contained the same elements as the first, regardless of position. Reaction time increased with the number of positions that the letters were displaced. Results indicate that order may be an important factor in retrieval from memory. (Author/BW)

Masters to be removed and copied are given. The worksheets are designed to reinforce computational skills and the concepts of largest or smallest numbers, as well as to provide practice is using a straightedge. (MK)

In an experiment, 13.5-month-old children were tested on 2- and 3-act sequences depicting familiar and novel events. Using elicited imitation, they reliably recalled the sequences in the correct temporal order. In a second experiment, 11.5 month olds accurately recalled 2-act sequences depicting familiar and novel events. (BC)

Lists six basic principles for building numeracy. Presents variety of activities in four categories of number concepts: spatial relationship, classifying, patterns, and correspondence. Suggests music, movement, and book ideas for each category of activity. Gives directions for making a geoboard and a reusable graph board. (DLH)

Several competing theories of short-term memory can explain serial recall performance at a quantitative level. However, most theories to date have not been applied to the accompanying pattern of response latencies, thus ignoring a rich and highly diagnostic aspect of performance. This article explores and tests the error latency predictions of…

Short-term memory for single-syllable words is negatively related to the number of semantic categories from which the words are drawn. Test results are inconsistent with any theory postulating a separate short-term memory that takes no account of semantic factors. (CHK)

Kindergarten children who had been given cues during instructional sessions on serial ordering performed significantly better on serial ordering posttests than did the control group (no instructional sessions). Author concludes that the acquisition of serial ordering capabilities depends in part on learning and not solely on the development of…
