Growth in working memory capacity, the number of items kept active in mind, is thought to be an important aspect of childhood cognitive development. Here, we focused on participants' awareness of the contents of their working memory, or "meta-working memory," which seems important because people can put cognitive abilities to best use…

In Experiment 1, Japanese children (4-, 5-, 7-, and 10-year-olds (n = 78)) and adults (n = 36), answered questions about the possibility of psychogenic bodily reactions, i.e., bodily outcomes with origins in the mind. The 4- and 5-year-old preschoolers typically denied that bodily conditions could originate in mental states. Developmentally,…

In 4 studies, the authors examined how intuitions about the relative difficulties of the sciences develop. In Study 1, familiar everyday phenomena in physics, chemistry, biology, psychology, and economics were pretested in adults, so as to be equally difficult to explain. When participants in kindergarten, Grades 2, 4, 6, and 8, and college were…

The Deese/Roediger-McDermott (DRM) paradigm was used to investigate developmental trends in accurate and false memory production. In Experiment 1, DRM lists adjusted to be more consistent with children's vocabulary were used with 2nd graders, 8th graders, and college students. Accurate and false recall and recognition increased with age, but…

The author investigated the importance of processing considerations within implicit memory in a developmental design. Second-graders (n = 87) and college students (n = 81) completed perceptual (word stem completion) and conceptual (category generation) implicit memory tests after studying target items either nonsemantically (read) or semantically…

English spelling is highly inconsistent in terms of simple sound-to-spelling correspondences but is more consistent when context is taken into account. For example, the choice between "ch" and "tch" is determined by the preceding vowel ("coach," "roach" vs. "catch," "hatch"). We investigated children's sensitivity to vowel context when spelling…

Research was designed to determine whether developmental differences in sensitivity to more peripherally presented material could be found under conditions in which overt eye movements during the presentation of task material were not possible. (Author)

Among kindergarten children, second-, fifth-grade, and college students, a gradual age-related increase was found in the ability to interpret an event from another person's perspective in light of that person's prior experiences. Various alternative explanations for the developmental trend were evaluated with data from subjects receiving prompts…

Four experiments examined the possibility that second and fourth graders and college students are sensitive to inference constraint when they make causal inferences and assess their understanding of a story. Inference likelihood and understanding ratings varied with constraint for all ages. Results suggest that comprehension monitoring and text…

Results support the inference that symbolic mediation is a measurably time-consuming process and that temporal factors are involved in the ontogenetic transition from single-link to symbolically mediated behavior. (Author/CB)

Second graders, fifth graders, and college students heard 12 stories that varied systematically by situational domain, outcome, and causal attribution. Students were asked to infer the story character's emotion at the end of the story and give reasons for it. Contributions and limitations of Weiner's attribution-emotion model are assessed in light…

When kindergarten, second grade, fourth grade, and college students listened to stories and were asked to predict and explain the story character's behavioral or emotional reaction to a new event, the use of personality attributions to predict and explain future reactions increased with age. (RH)

Kindergarten, second-grade, fifth-grade, and college subjects were tested in a serial-position recall task under each of four conditions: Visual stimuli/visual recall cue, visual stimuli/auditory recall cue, auditory stimuli/visual recall cue, auditory stimuli/auditory recall cue. Visual stimuli were pictures of common animals and objects;…

Four experiments were conducted to extend the "descriptions" approach to differences in using retrieval cues among second and fourth graders and college adults. Results indicate that deficits in discriminability and constructability contribute independently to developmental differences in using retrieval cues and suggest reasons for such…
