Digit comparison is strongly related to individual differences in children's arithmetic ability. Why this is the case, however, remains unclear to date. Therefore, we investigated the relative contribution of three possible cognitive mechanisms in first and second graders' digit comparison performance: digit identification, digit--number word…

A primary objective of development is to build a knowledge base. To accumulate knowledge over time and experiences, learners must engage in productive processes, going beyond what is explicitly given to generate new knowledge. Though important to accumulating knowledge, these processes are also easily disrupted. Individuals often depend on surface…

We examined the role of executive attention, which encompasses the common aspects of executive function and executive working memory, in children's acquisition of two aspects of mathematical skill: (a) knowledge of the number system (e.g., place value) and of arithmetic procedures (e.g., multi-digit addition) and (b) arithmetic fluency (i.e.,…

The purpose of this research was to investigate developmental changes in encoding processes. It attempted to determine the extent to which children of varying ages utilize semantic (denotative or connotative) and acoustical encoding categories in a short-term memory task. It appears to be a reasonable assumption that as associational hierarchies…

Second-grade children were explicitly supplied with zero, one, two, or three components of information to specify the respective contributions of various sources and amounts of acquired strategy-utility information. Metacognitive knowledge was evidenced only when the training regiment included the complete set of critical metacognitive components.…

The effectiveness of two types of retrieval cues was assessed with second- and sixth-grade children. After a single presentation of a list of words, the children first recalled as many of the words as they could. Following free recall, children in each grade were given either conceptual (category names for words on the input lists) or acoustic…

In a study of the effects of pictorial stimuli on story recall, 64 second graders were randomly assigned to two experimental groups and two control groups. The learning materials consisted of two orally presented ten-sentence stories. The experimental subjects viewed pictures while the stories were read, and the control groups followed the printed…

First and second graders studied words by means of a talking computer system that highlighted and pronounced orthographic units in words that were touched with a light pen. Results suggest that presenting words as wholes is at least as helpful for short-term learning as presenting them segmented. (LB)

Two experiments were conducted to assess the effects of elaborated presentation on noun-pair retention. A 2 x 2 factorial design was used with aural-verbal presentation (standard versus elaborated) and visual-pictorial presentation (standard versus elaborated). Subjects for one experiment were 64 second-grade children from a Mexican-American…

Twenty children in each of grades 2 and 4 were given a reaction time task of the type in which Sternberg (1969) shows high-speed, serial, exhaustive scanning of information in memory. On each trial subjects were asked to memorize two, four, or six pictures and were then presented with a single picture probe. The subject made a key-pressing…

Investigates the relationship between auditory and visual processing modality and strategy instruction in first- and second-grade children. Determines sentence strategy to be effective for both auditory and visual processing. (HOD)
