Objective: When students learn or solve problems, attentional resources are depleted; rest breaks may restore cognitive functioning in support of learning. Research framed by attention restoration theory holds that exposure to natural environments may be another means to restore attentional resources. The study investigated the effects of…

Despite historical emphasis on "specific" learning disabilities (SLDs), academic skills are strongly correlated across the curriculum. Thus, one can ask how specific SLDs truly are. To answer this question, we used bifactor models to identify variance shared across academic domains (academic "g"), as well as variance unique to…

Individuals with an aptitude for interpreting spatial information (high mental rotation ability: HMRA) typically master anatomy with more ease, and more quickly, than those with low mental rotation ability (LMRA). This article explores how visual attention differs with time limits on spatial reasoning tests. Participants were assorted to two…

This paper reports some experiments on probabilistic reasoning designed to investigate the impact of the probabilistic problem presentation format (verbal-numerical and graphical-pictorial) on subjects' confidence in the correctness of their performance, other than the calibration between confidence and accuracy. To understand the potential effect…

Developing fluency in arithmetic facts is instrumental to mathematics learning. This study compares the effects of two practice conditions on children's fluency in simple multiplication facts. Third and fourth graders in the Netherlands (N = 282) practised in either a conventional "recall" condition where they produced answers to…

The adoption of active learning instructional practices in college science, technology, engineering, and mathematics (STEM) courses has been shown to result in improvements in student learning, contribute to increased retention rates, and reduce the achievement gap among different student populations. Descriptions of active learning strategies…

This study examined adult age differences on five tests of divergent thinking: associational fluency, expressional fluency, ideational fluency, word fluency, and consequences. Our hypothesis was that young adults ( M = 20.53, n = 60) would score higher than old adults (M = 72.10, n = 60) under standard timed test conditions, but old adults would…

Speed of performance on the Revised Block Design, Picture Arrangement, and Object Assembly subtests of the Wechler Intelligence Scale for Children was related to chronological age and problem-solving ability. Speed assumed a steadily increasing role with increasing age. Children who solved the items quickly were better problem solvers. (Author)

Models relating individual and group problem solving solution times under the condition of limited time (time limit censoring) are presented. Maximum likelihood estimation of parameters and a goodness of fit test are presented. (Author/JKS)

Discusses the problems of using chronometric analysis, a common cognitive psychological method, for educational assessment. Suggests that cognitive assessment has not reached the precision needed to analyze individual differences. (FMW)

Forty-one students in two third grade classes, including special education students, participated in an action research project conducted jointly by two university supervisors, three teachers, and three student teachers. The "Minute Math" project involved students in predicting and graphing their test scores on a weekly conventional timed test of…

A study evaluated the effects of explicit timing procedure on problem completion rates and accuracy levels in 40 African-American third-grade students. Results showed that the explicit timing procedure increased problem completion rates. A decreasing trend in percentage of problems correct also occurred. Recommendations for educators are…

Adoptive parents and their adoptive and natural children took IQ tests. Speed of solution correlated with verbal IQ and .51 with performance IQ among the parents. Mothers' speed correlated negligibly with scores of adoptive and natural children. Fathers' speed correlated more with their natural than adopted children's performance scores.…

Evaluated effects of time pressure on attributions made and solutions generated in hypothetical social problem situations by aggressive and nonaggressive boys. Found a greater level of arousal in the time pressure condition than the untimed condition across all subjects and greater numbers, more types, and more aggressive solutions. (SD)
