This study examined (1) whether subjects of different ages tend to rely on different kinds of visual information when given a choice; and (2) whether the ability to use spatial and identity information accurately in a recognition task changes developmentally. (Author/SB)

Four experiments examined whether letter names at the ends of words are equally useful as letter names in the initial position. Findings indicated that 4- and 5-year-olds derived little benefit from such information in reading or spelling, although adults did. For young children, word-final information appeared to have less influence on reading…

Children and adults were tested on a mental rotation task in which letters were presented in different orientations. The task was performed by itself or with a memory task. Results indicated that the relation of response time to stimulus orientation in the rotation task was the same in both conditions. (BC)

Examines the processing of physical and nominal features of letters by children from grades 1, 2, and 6. Examines processing strategies in relation to reading ability. (BD)

A modification of Posner's letter-matching paradigm is employed to study the development of abstract visual and name codes for letters in second, fourth, and sixth grade students. (CM)

One hundred twenty kindergarten, second, third and combined fifth and sixth grade children were asked to cross out the letter "e" while silently reading appropriate prose passages. The children's ability was dependent upon grade level and whether the "e" was silent, pronounced, or in the word "the". (BD)

Children from kindergarten through grade 2 were asked to copy, then print from memory, each of the 41 reversible letters and numbers administered individually on slides presented in random order. The main findings of an experiment with 179 children drawn from two elementary schools show that mirror-image reversals and other errors (1) take place…

As part of a study of the feasibility and effect of teaching Navajo children to read their own language first, the results of analysis of grapheme and unit frequencies noted in the speech of Navajo 6-year-olds are presented in this report. Material gathered by means of interviews conducted by 22 adult Navajos with over 200 Navajo children is…

Age effects on increasing number of targets in a letter-canceling task were examined. Age differences increased with practice but reached significance only in Session 9. The oldest group made the most omission errors. All age groups improved with practice. (Author)

Groups of eight- and ten-year-olds and adults visually searched for the presence of a target letter or number in fields of items that were either of the same or a different category (letter or number) than the target. (JMB)

Kindergarten, second, and fourth grade children were asked to recall letter sequences on a task which required the use of a verbal strategy, a positional strategy, or either of the two strategies. (BD)

Compared age differences in search tasks for two groups of children (N=40) and an adult control group (N=20) who completed a similar visual search task, i.e., determining whether a predesignated target character occurred in a character string. The mean search latency decreased with age. Results showed a qualitative difference in processing letters…

Three experiments were performed with young and aged female volunteers (mean ages approximately 25 and 70 years respectively) to evaluate coding ability with ordered and free recall tasks. (BD)

High frequency words typed in normal and alternating case were presented tachistoscopically in the fovea and parafovea to children and adults. Dependent measures were percentages of letters and words correct. Few differences between age groups were found. Serial position curves also showed similarities across grades in the parafoveal information…
