Linear measurement is more than just learning how to use a ruler. In the early grades, measurement activities develop students' understanding of the properties of objects as well as what it means to measure objects. Hands-on activities can enable students to explore such measurable properties as height and length, and direct comparisons of various…

Despite a century of research, the mechanisms underlying short-term or working memory for serial order remain uncertain. Recent theoretical models have converged on a particular account, based on transient associations between independent item and context representations. In the present article, the authors present an alternative model, according…

A. Pollatsek, E. D. Reichle, and K. Rayner argue that the critical findings in A. W. Inhoff, B. M. Eiter, and R. Radach are in general agreement with core assumptions of sequential attention shift models if additional assumptions and facts are considered. The current authors critically discuss the hypothesized time line of processing and indicate…

This study examined the relationship between witness age, narrative features in testimony, and the perceived credibility of witnesses. Ninety older and young adult witnesses to a staged theft were videotaped as they freely recalled crime events. Later, participant-jurors viewed the videos and assessed the witnesses' credibility. Operational…

Five experiments were conducted to explore trial order and retention interval effects upon causal predictive judgments. Experiment 1 found that participants show a strong effect of trial order when a stimulus was sequentially paired with two different outcomes compared to a condition where both outcomes were presented intermixed. Experiment 2…

In the first of two studies, fifth and eighth graders and undergraduates were shown the patterns of three hypothetical group members' preferences regarding three alternatives. The hypothetical groups members' preferences were ranked first, second, third (Group O); or desirable, neutral, undesirable (Group PN). The subjects' task was to use the…

The inclusion of group activities based on theories of cognitive development within day care settings is urged. Several examples of classroom-tested activities are included. (ED)

First and second graders (n=81) were randomly partitioned into experimental and control groups. The experimentals were given experiences in sorting and seriating objects. Significant treatment and grade effects (p.01) were found on a seriation test, but no significant relationships between classification and transitivity nor seriation and…

ASPECTS OF NEUROLOGICAL RESEARCH ARE PRESENTED UNDER THE TOPICS OF NEUROLOGICAL GROWTH AND DEVELOPMENT, CEREBRAL DOMINANCE, "SPLIT-BRAIN" SYNDROME, AND SEQUENCING. THE FIRST TWO AREAS INDICATE THAT ASSESSMENT OF A CHILD'S NEUROLOGICAL DEVELOPMENT MUST TAKE INTO ACCOUNT VARIATION OF RATE AND DEGREE OF DEVELOPMENT, AND THAT THE SIGNIFICANCE OF…

A testing instrument, the Experimental Phoneme Sequence Test (EPST), was devised to collect baseline information for studying receptive knowledge of phoneme sequencing in normal articulating kindergarten and elementary school children. One hundred kindergarten through fourth-grade children, five male and five female subjects at each half-year…

Deals with memory for lists of items. The literature is briefly reviewed, and the main difficulties for traditional explanations of serial order effects are noted. (RK)

On the basis of these findings, both the measurement techniques of previous studies and Piaget's analysis of seriation are challenged. (Author)

Deficits in position memory particularly seemed to be the major distinguishing variable between normals and retardates in the present study. (Authors)

Using recognition rather than recall test procedures gives results which are inconsistent with the main features of the visual trace model for short-term memory. (Author)

Results suggest that Ss store some of the auditory and visual information in modality-dependent memory systems and that storage order determines recall accuracy. (Author)
