This research developed a multimodal picture-word task for assessing the influence of visual speech on phonological processing by 100 children between 4 and 14 years of age. We assessed how manipulation of seemingly to-be-ignored auditory (A) and audiovisual (AV) phonological distractors affected picture naming without participants consciously…

Three experiments obtained same-different judgments from children and adults to trace normal development of local and global processing of hierarchical visual forms. Findings indicated that reaction time was faster on global trials than local trials; bias was stronger in children and diminished to adult levels between ages 10 and 14. Reaction time…

Three experiments examined the memory-preserving effects of reactivation and reinstatement reminders following 6-month-olds' learning and forgetting of an operant task. Findings indicated that a single reactivation reminder extended infants' memory of an operant mobile task for 2 weeks, a single reinstatement extended it for 4 weeks. A single…

This study tested 5- and 8-year-olds and adults in a bisection task with a sequence of stimuli in which time and number co-varied. Findings indicated that the number of stimuli interfered with 5-year-olds' performance on the temporal bisection task. Number interference decreased both with age and counting strategy. In the numerical bisection task,…

Examined in three studies EuroCanadian and Native Canadian children's memory for stereotypic behaviors attributed to ingroup and outgroup members. Found that outgroup favoritism, typically found among low-status group members, was reversed among Native Canadian children attending a heritage school. Age and cognitive development level predicted…

Five- and 6-year-olds heard stories in which a character sorted items into two locations. Found that children could reject a report of the character's belief when the character had a false belief more easily than a belief in which an object known to the character was described using an unknown term. Children found it easier to predict incorrect…

Links between theory of mind and episodic memory involving autonoetic consciousness were investigated in Japanese 4- to 6-year-olds. After age was controlled for, most theory of mind abilities showed no interrelations. Own and others' belief understandings on deceptive appearance tasks were solely related to source memory. Results suggest that…

Compared the timecourse of inhibition of return (IOR) of young children to that of older children and adolescents in single and double cue procedures. Found no IOR in the young children unless a double cue was used, but for older groups, found IOR at all intervals with a double cue and the typical crossover pattern, with early facilitation…

Examined effects of a click signaling arrival of a visual stimulus to be timed on temporal discrimination in 3-, 5-, and 8-year-olds. Found that in all groups, the proportion of long responses increased with the stimulus duration, although the steepness of functions increased with age. Stimulus duration was judged longer with than without the…

This study investigated attention to and recognition of components in compound stimuli among infants and preschoolers. Oddity tasks with preschoolers and familiarization/novelty-preference tasks with infants demonstrated successful discrimination among stimuli components on basis of edge property information. Matching tasks with preschoolers and…

Investigated the relationship between auditory temporal processing of nonspeech sounds and phonological awareness ability in 8- to 12-year-olds with a reading disability, placed in groups based on performance on Tallal's tone-order judgment task. Found that a tone-order deficit did not relate to performance on order processing of speech sounds, to…

Examined influence of newly acquired information on 5- to 7-year-olds' memory and general representation of a personally experienced novel event. Found that advance information specific to the event led to better recall and better integration of the experience into a general event representation both soon after the event and 4 months later.…

This study contrasted and compared the extent to which phoneme and rhyme-based skills and letter-sound knowledge predicted 4- and 5-year-olds' performance in the analogy task and in a test of single work reading. Findings suggested that the balance of skills that children drew upon was determined by the demands of the task. Findings pose…

Two studies examined how task content that activates predator-avoidance affects preschool children's performance on a false-belief task. Findings indicated that the proportion of correct answers on the playmate-avoidance task was greater than that for the predator-avoidance task, suggesting that activation of the predator-avoidance system…

Examined whether age-related working memory deficits in learning disabled (LD) readers across four age groups (7, 10, 13, and 20) reflected retrieval efficiency or storage capacity problems. Found that LD readers' working memory performance was inferior to skilled readers' on verbal and visual-spatial working memory tasks across all ages.…
