Investigated the processes that 158 children in grades 3 through 6 used for spelling. Children had the most difficulty with spellings based on morphological information and the least with those based on invariant sound-spelling relationships. (SKC)

Investigated the application of verbal praise as a reward with 84 third and fourth grade children who completed a digit-symbol coding task under contingent versus noncontingent and direct versus implicit reward conditions. Noncontingent rewards possessed no significant reinforcer effect under either reward condition. (SKC)

Four studies investigated whether inconsistency of children aged four to six on developmental tasks may reflect a misinterpretation of the experimenter's intent in communication under repeated questioning. (SKC)

Tested the comprehension of children aged 4-12 of double negation in Chinese. Young children interpreted double negation as simple negation. Only the oldest children consistently interpreted double negatives as equivalent to affirmative sentences. (SKC)

Examined matching-to-sample procedures that might result in emergence in preschool children of conditional behavior that was never explicitly taught. Children were asked to match a novel and a familiar picture to a spoken word which was English or nonsense. (SKC)

Examines interactions between timing accuracy and muscular parameters in children aged five who performed a visuomotor game. Five images were successively presented on a television display at precisely timed intervals for a total period of 11 seconds. Results suggest that timing accuracy is dependent on action-produced sensory cues. (RWB)

Four experiments examined the spelling capability of students in grades 1, 2, 3, 4, 7, and college. Results suggested that reading unit size increases with age and reading ability. Younger children, like adults, unitize common words, and unitization of less common words increases as word configurations become more familiar. (RWB)

Investigated relationships among metamemory, memory behavior, and memory performance of children aged 4 to 6 in two experiments. Results indicated an increase in preschoolers' ability to establish relationships between cues and targets even if these were not highly associated. (RWB)

Five experiments examined the cued recall of the last target words of primarily four-word (Bus-Airplane-Car-Train) category stimuli by children and adults. Focused on problems of gaining access to episodic search sets in recall. Results suggested that access to search set is more problematic for children than for adults. (RWB)

Assesses children's comprehension of "because" and "so" on enactment and sentence completion tasks. Results provide evidence against a componential model for the acquisition of causal connectives. Supported is the position that understanding of relational terms is initially context dependent; linguistic development generates context independent…

Three studies involving groups of four- to five-year-old children examined whether the discriminative properties of prompts are critical for establishing a difficult (septagon, octagon) discrimination through time delay. Results confirm superiority of multiple-stimulus, distinctive-feature prompts, implying that stimulus dimensions of prompts are…

Investigates to what extent discrimination learning through time delay of multistimulus, distinctive-feature prompts is a function of the inclusion and configuration of the S-prompt. Results of two experiments with children aged four and five indicate that most subjects did not learn the task assigned unless two distinctive-feature prompts were…

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classifications of younger and older subjects. Results support a differential-sensitivity view of perceptual development which asserts that individuals at all ages primarily perceive and use separate relations. (RWB)

This study investigated why children reproduce and/or reconstruct text in a classroom. The focus was on social classroom variables. Results supported the prediction that students would recall text differentially according to the response interaction pattern maintained with teachers. (Author/DB)

This study investigated whether misunderstanding of metaphor is attributable to inability to discover the ground, the demands of a particular form of metaphor, or surface aspects of metaphors. Results indicated task demands posed by predicative metaphors proved greater than those posed by topicless metaphors. (Author/DB)
