A pretest-training-posttest design assessed whether training to improve spatial skills also improved mathematics performance in elementary-aged children. First grade students (mean age = 7 years, n = 134) and sixth grade students (mean age = 12 years, n = 124) completed training in 1 of 2 spatial skills--spatial visualization or form…

Previous research has demonstrated that cognitive offloading (i.e., externalizing mental processes) is useful for immediate problem solving. However, long-term effects of cognitive offloading on subsequent problem solving without offloading are remarkably understudied. Our main goal was to investigate the effects of representation control (i.e.,…

Many studies in the past decades have focused on low and typical mathematics achievers, yet little is known about children with high mathematics achievement, particularly at a young age. The current study aimed to fill this gap and started from the early work of Krutetskii (1976) as a theoretical lens to study the characteristics of high…

Spatial ability predicts success in STEM (Science, Technology, Education, and Mathematics) fields, particularly chemistry. This paper reports two studies investigating the unique contribution of mental rotation ability to spatial thinking in a STEM discipline. Using authentic disciplinary tasks from chemistry, we show that the difficulty of a…

The overarching goal of this 2-phase study was to investigate the contributions of relational reasoning to mathematical thinking and performance for 790 primary and middle-school Chinese students. Phase I of the study was undertaken to establish the reliability and validity of the Test of Relational Reasoning-Junior (TORRjr), a 32-item measure…

In 2 experiments, college students read a 4-paragraph text on how the human circulatory system works and were instructed to form a mental image of the events described in each paragraph from the perspective of their own body (first-person perspective group) or from the perspective of a fictitious person facing them (third-person perspective…

Understanding many scientific phenomena, processes, or systems may be especially dependent on a student's ability to visualize or manipulate spatial information in order to construct mental representations. One instructional technique often included in science texts to help students to understand difficult concepts is the use of concrete or…

Rational number understanding is a critical building block for success in more advanced mathematics; however, how rational number magnitudes are conceptualized is not fully understood. In the current study, we used a dual-task working memory (WM) interference paradigm to investigate the dominant type of strategy (i.e., requiring verbal WM…

In a series of experiments, we tested a recently proposed hypothesis stating that the degree of alignment between the form of a mental representation resulting from learning with a particular visualization format and the specific requirements of a learning task determines learning performance (task-appropriateness). Groups of participants were…

Asking students to imagine the spatial arrangement of the elements in a scientific text constitutes a learning strategy intended to foster deep processing of the instructional material. Two experiments investigated the effects of mental imagery prompts on learning from scientific text. Students read a computer-based text on the human respiratory…

A considerable amount of research has been undertaken to provide insights into the valid assessment of team performance. However, in many settings, manual and therefore labor-intensive assessment instruments for team performance have limitations. Therefore, automated assessment instruments enable more flexible and detailed insights into the…

In agreement with prior studies, syntactic order produced better recall, and recall errors were semantically related to the narrative. The more vivid versions of the paragraphs produced higher recall suggesting that imagery may play a role in recall. (Authors)

Students identified by talent search programs were studied to determine whether spatial ability could uncover math-science promise. In Phase 1, interests and values of intellectually talented adolescents (617 boys, 443 girls) were compared with those of top math-science graduate students (368 men, 346 women) as a function of their standing on…

From evidence of this study it appears that a person will learn more from a prose passage if he forms images of the things and events described in the passage. (Authors/MB)

A spatial-arrangement or word-arrangement mnemonic experiment was conducted in which college students studied six lists of 12 words each under conditions of word pattern and/or mnemonic instruction. Both the link mnemonic and distinctive word arrangements enhanced recall during acquisition, but only word-arrangement had a significant effect on…
