Although human infants demonstrate early competence to retain visual information, memory capacities during infancy remain largely undocumented. In three experiments, we used a Visual Paired Comparison (VPC) task to examine abilities to encode identity (Experiment 1) and spatial properties (Experiments 2a and 2b) of unfamiliar complex visual…

The magnitude of the association between developmental dyslexia (DD) and motion sensitivity is evaluated in 35 studies, which investigated coherence motion perception in DD. A first analysis is conducted on the differences between DD groups and age-matched control (C) groups. In a second analysis, the relationship between motion coherence…

A forced-choice observer-based testing procedure was used to determine pure-tone hearing thresholds for 2- to 4-week-old infants. Stimuli were 500-ms tone bursts of 500, 1,000, or 4,000 Hz with 500-ms intervals between tone bursts. Stimuli were presented monaurally by means of an insert earphone. Each 15-s trial consisted of 5 tone bursts,…

This study sought to assess the ontogenetic course of three classes of size-value phenomena. Size-value phenomena refers to the observation that valued and neutral objects physically equal in size are judged as unequal. Results are discussed in terms of perceptual development. (ST)

The effect of grammatical phonological rules (those in English) and nongrammatical (those in other languages) on the learning and reproduction of morpheme-length utterances and the role of maturation on this effect were examined. Children preschool through second grade were the subjects. There were no significant differences at any grade level…

To determine short-run effects of experimentally imposed leadership roles, a sample of 221 Boy Scouts (aged 10 to 17) was formed into (usually) 4-man teams that competed in 3 skill games. One member of each team was randomly designated as captain, with power to administer and reward. Captains who were leaders in their troops responded to becoming…

This study was designed to examine the effects of age and sex on susceptibility to field dependence training and to determine whether the field dependence phenomenon is a function of cognitive style or of a general inability to make correct judgments because of confusing and inaccurate information. (MS)

To test the assumptions that children's perceptions of a news program affect their learning and that their perceptions are in turn affected by age and program context, a study was undertaken involving 435 third through seventh graders. The specific independent and perceptual variables examined were: believability, liking the story and program,…

The purpose of this book is to report and interpret a group of research studies relating to social-cognitive development in early childhood through adolescence. Adults interpret the covert psychological properties of other people, their abilities, knowledge, motives, attitudes, perceptions, and intentions relevant to concrete situations. An infant…

This document describes the research activities of the Syracuse University Evaluation and Research Center for the year September 1, 1966 through August 31, 1967. This final report is organized on the basis of six research projects, which have been abstracted under the following titles and numbers: (1) Experiments in Grammatical Processing in…
