Word frequency is an important predictor of lexical-decision task performance. The current study further examined the role of this variable by exploring the influence of frequency trajectory. Frequency trajectory is measured by how often a word occurs in childhood relative to adulthood. Past research on the role of this variable in word…

To act and think, children and adults are continually required to ignore irrelevant visual information to focus on task-relevant items. As real-world visual information is organized into structures, we designed a feature visual search task containing 3-level hierarchical stimuli (i.e., local shapes that constituted intermediate shapes that formed…

The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

Tests the theoretical proposition that developmental increase in memory span results from a corresponding increase in the use of grouping strategies. (BJD)

This study examined the hypothesis that perceptual errors on a task requiring subjects to take different viewpoints could be explained in terms of response bias. Results were consistent with response bias hypothesis: making an egocentric error is different from behaving in an egocentric manner. (Author/SB)

TWO STUDIES ON LEARNING SET FORMATION IN CONTINUOUS, DISCOURSE-PROGRAMED MATERIAL WERE CONDUCTED. ONE STUDY WAS CONDUCTED WITH 315 COLLEGE STUDENTS, THE OTHER WITH 141 SIXTH-GRADE STUDENTS. THE MAJOR INDEPENDENT VARIABLE WAS THE NUMBER OF PROGRAMED UNITS ADMINISTERED. THE DEPENDENT VARIABLES WERE PRE- AND POST-ACHIEVEMENT TEST SCORES AND ERROR…

Research on the structures and processes involved in simple mental arithmetic is reviewed. Results suggest that mental arithmetic is a memory retrieval phenomenon, which develops with the experiences of elementary school and can be understood in general as retrieval from organized network representations. Simple mental addition with basic facts…

IN PROJECT I, A FREE ASSOCIATION TECHNIQUE WAS USED TO ANALYZE CHILDREN'S VOCABULARIES IN TERMS OF DERIVATIONS OF WORDS USED, THE RELATION OF WORD DERIVATIONS TO THE CHILD'S LANGUAGE LEARNING, AND THE EFFECTS OF DERIVATIONAL STRUCTURE ON COGNITION. IT WAS FOUND THAT "FREE" ASSOCIATIONS TEND TO OCCUR WITHIN "SETS" DEFINED BY WORD SOURCES. PROJECT…
