We investigate whether a spatial representation of a search task supports 4- to 7-year-old children's information-search strategies, relative to their performance in a question-asking game. Children played two computationally and structurally analogous search games: a spatial search task, the maze-exploration game, in which they had to discover…

Rehearsal is a form of self-talk used to support short-term memory. Historically, the study of rehearsal development has diverged from the study of self-talk more generally. The current experiment examines whether two characteristics of self-talk (impact of task difficulty and self-talk's narrative vs. planning purpose) are also observed in…

Understanding measurement units is critical to mathematics and science learning, but it is a topic that American students find difficult. In 3 studies, we investigated the challenges underlying this difficulty in kindergarten and second grade by comparing performance on different versions of a linear measurement task. Children measured crayons…

Investigated interactions between stress level of syllables and articulatory difficulty as influences on children's early words. Subjects were 32 two-year olds asked to imitate nonsense words and syllables that varied in articulatory difficulty. Found that both factors had significant effects on aspects of children's imitations. (MOK)

Old and young adults participated in two experiments involving a standardized, hierarchically organized event. In interviews that assessed memory of the event, older subjects reported fewer event actions than did the young. Memory of old and young was influenced similarly by the hierarchical structure of the event. (RH)

Investigated the range and limits of cognitive reserve capacity as a general approach to the understanding of age differences in cognitive functioning. Group differences were magnified by training to such a degree that age distributions barely overlapped at posttests. The testing-the-limits approach promises increased understanding of cognitive…
