Learning the meanings of Arabic numerals involves mapping the number symbols to mental representations of their corresponding, approximate numerical quantities. It is often assumed that performance on numerical tasks, such as number line estimation (NLE), is primarily driven by translating from a presented numeral to a mental representation of its…

With team-based structures replacing traditional hierarchical systems, the purpose of this paper was to explore the concept of shared leadership and its impact on improving team performance. The five underlying mechanisms that form the components which drive shared leadership, namely (1) trust, (2) empowerment, (3) age and maturity, (4) fair…

The present study uses oral interviews with foreign language learners in search of influential factors in their language learning histories. The sample for the study was drawn from a larger sample of intermediate/advanced learners of English as a foreign language with a minimum of 10 years of exposure/instruction. The sample includes 6 early…

Coaches have always needed to respond to differences in sport and have always been concerned with finding hard-working kids who mesh well as a team. While coaches still try to build team cohesiveness, today's coaches must respond to complex issues related to diversity and are expected to be politically correct. The purpose of this article is to…

Two experiments examined age differences in children's dual-task performance. Findings indicated that when capacity for single-task performance was controlled, age differences between second and fifth graders did not exist in performance of dual-tasks of equal priority. When tasks had different priorities, only fifth graders could differentially…

Evaluates preschoolers' ability to distinguish left-right mirror-images of objects on a memory task and ability to name rows of objects on a page in a consistent lateral direction. Abilities were assessed first without specific instructions on the relevance of left-right information and then with instructions. (Author/AS)

Investigated whether individual and developmental differences in look duration were correlated with latency to disengage fixation from a visual stimulus for 3- and 4-month olds. Found that look duration was correlated with disengagement latency. Three-month olds showed slower latencies than 4-month olds. Long-looking infants showed greater…

Two studies were conducted with 8- and 10-year-old children to examine sources of age and skill differences in verbal analogical reasoning. Discussion focuses on the child's "problem space" for the analogy task and possible differences in task understanding that lead to strategy and process differences in older versus younger and skilled versus…

Examined the hypothesis that processes other than those related to concepts about ability produce helplessness in children younger than 10. Found that eight year olds did not experience helplessness in response to feedback about their failure in an achievement task but did experience helplessness when they failed to perform a physical task. (MM)

Results indicate that the auditory stimulation in no way affected task performance. Author argues that great amounts of money should not be spent by either schools or parents in order to eliminate moderate amounts of noise from a child's academic environment. (Author/CB)

Assessed age-related changes in 2- to 4-year olds' verbal and nonverbal memory for the same unique event. Found that children's performance on each memory measure increased as a function of age. Children with more advanced language skills reported more during the verbal interview and exhibited superior nonverbal memory relative to children with…

Examined the relative contributions of internal and external sources of variation in children's suggestibility in interrogative situations. Found that internal sources of individual differences in suggestibility measured on a suggestibility test did influence children's answers during an interview, but that external sources or interview styles had…

Examined performance of first through sixth graders on conditional-inference task, using causal conditionals and a generation of alternatives task. Found a steady age-related increase in uncertainty responses to two uncertain logical forms and an increase in production of disabling conditions for "modus ponens." Individual differences in inference…

This study examined effects of individual differences in speak-span scores and variations in memory demands on class-inclusion performance of 10-, 13-, and 15-year-olds. Results from regression analyses and the mathematical model indicated that differences in age, speak span, and memory load affected performance. Effects of speak span and memory…
