In this study, the development of comprehension of essential and nonessential aspects of counting is examined in children ranging from 5 to 8 years of age. Essential aspects, such as logical rules, and nonessential aspects, including conventional rules, were studied. To address this, we created a computer program in which children watched counting…

The lexical decision task is probably the most common laboratory visual word identification task together with the naming task. In the usual setup, participants need to press the "yes" button when the stimulus is a word and the "no" button when the stimulus is not a word. A number of studies have employed this task with developing readers;…

First, second, and fourth graders listened to stories containing an inconsistent goal and outcome. Children provided a causal inference for the inconsistency, and attributed the inference to themselves or the story. Children's attributions were related to whether the story contained causal information linking the inconsistent events. (BC)

Examines fourth grade children's memory for information contained in target sentences presented 24 hours earlier. Examines the occurrence of interference by presenting multiple choice response options consisting of a correct word, a new word, and a word which occurred in a previous sentence. Attempts to extend the principles of frequency theory.…

On discrimination learning trials which allowed subjects to press an information key when in doubt, retarded children made significantly more presses than control groups. Results confirmed the hypothesis that retarded children would be more outerdirected than normal children in a situation in which distractibility could not play a role. (Author/GO)

Analysis of the frequency and nature of error and post-error responses in serial choice reaction times of 84 children between 5 and 12 years essentially replicate findings in adults. (Author/MP)

A modified viewer rotation procedure was used to contrast two possible explanations of spatial egocentrism in spatial perspective tasks. Subjects were 60 children in first, third, and fifth grades. (MP)

Findings of four investigations involving five through seven year olds suggest that, even though children can make relatively accurate judgments of their knowledge states, they tend to overestimate their competence when assessing their knowledge in relation to performance on a task. (RH)

Investigated memory span and memory scanning in both auditory and visual modalities of 24 good and poor, 10-year-old readers. The major finding was that short-term memory function deteriorated over time in the poor reading group. (Author/LLK)

This study examines the role of verbal labels in picture recognition by 5-year-olds and adults to find out if recognition accuracy and time of recognition choice is influenced by the use of labels. (GO)

Examines young children's ability to use simple morphological relations among words as a source of information about the words' spelling. Found that children used morphological relations among words only to a small extent. Suggests that although phonology plays an important role in early spelling, young children can also use other sources of…

Examined phonological processing in a Chinese reading test and on several phonological processing tasks. Found that younger normal and poor readers of Chinese made more semantic and visual errors, whereas older and normally achieving children made more phonologically related errors. Normally achieving readers also performed better than poor…

Results were interpreted as supporting an inhibition deficit theory of mental retardation. (Authors)

Malawian children and young adults displayed sensitivity to static information for depth when stimulus objects subtended equal visual angles. When the more distant object was larger but subtended a smaller visual angle than the nearer, subjects tended to base judgments on retinal size. Motion paralax information increased accuracy of judgments of…
