The nature of the childhood development of immediate recall has been difficult to determine. There could be a developmental increase in either the number of chunks held in working memory or the use of grouping to make the most of a constant capacity. In 3 experiments with children in the early elementary school years and adults, we show that…

Even when two-digit numbers are irrelevant to the task at hand, adults process them. Do children process numbers automatically, and if so, what kind of information is activated? In a novel dot-number Stroop task, children (Grades 1-5) and adults were shown two different two-digit numbers made up of dots. Participants were asked to select the…

The potency of Pascual-Leone's M construct was demonstrated by experimental production of decalages on combinatorial reasoning tasks. Logical and perceptual task characteristics remained constant while the number of variables was varied so that processing demands, relative to processing capacities, were the same for subjects at each of three age…

Twenty first-graders observed an adult model perform a quantity conservation task. The children were then tested on a series of generalization tasks immediately, after one week, and after three months. The results suggested that the social experience of observation appeared to activate a cognitive restructuring of the children's mental operations.…

Two experiments examined processes underlying contextual facilitation effects in second, fourth, and six graders and adults. Patterns of response latencies indicated that, for the youngest children, facilitation for stimuli presented in a related context was attributable to an automatic activation process. (Author/MP)

Investigates the influence of word meaning on lexical processing in children and adults. Examines developmental trends in lexical decisions for abstract and concrete words. Concludes that word meaning influences lexical processing in children but that there is a developmental shift in the kinds of semantic characteristics that are available for…

It was hypothesized that slight modifications in word association test (WAT) instructions would have no discernible effect on the responses of college students, but would produce significantly different response hierarchies generated by young children. (Author/MS)

Second-grade children, third-grade children, and adults judged whether pictures were members of a positive or negative memory set while trying to ignore irrelevant words printed inside the pictures. (JMB)

After presenting a brief description of the principles of a story grammar, some experimental results are summarized to illustrate the power of story schemata in controlling recall. Specially constructed versions of four stories were used with second, fourth, and sixth graders and in a second experiment with adults. One version of each story was…

While semantic development has been alleged to proceed slowly, reading instruction begins early in the child's school career. Yet, little research has been addressed toward understanding how beginning readers extract meaning from the printed word. This paper reports two experiments that measured latencies in a picture-word interference task to…

The purposes of this study were to examine priority of recall of newly learned items (PRNI) from a developmental standpoint and to investigate whether preschool children are capable of using the attentional strategy employed by adults in free recall learning (FRL) of new items. In the first experiment the PRNI effect was examined from a…

Provides direct evidence of developmental differences in the processing of item-specific information, discussing how these differences affect recognition as well as recall performance in second graders, fifth graders, and college adults. Results suggest that retention varies as a result of the degree to which children differ from adults in…

This report summarizes four groups of experiments examining the nature of basic perceptual processes in reading. The first group examined the relationship of English orthography to reading, specifically the transfer of information from the icon to short-term memory. The second group of experiments examined the use of peripheral information…

The assumption that "ideal" text grammars are valid descriptions of the schemata used by children to organize their recall of text was challenged in a study involving 150 elementary school children. The children, all with above-average reading ability, were classified as having one of three types of schemata: theme-initial (identifying…

Explores the generality of findings relating intelligence to Inspection Time (IT), the exposure necessary to judge which of two lines is longer, in two studies using normal children and mentally retarded adults. Results showed the relationship between IT and performance IQ was lower in the mentally retarded group. (JAC)
