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…

A large part of the empirical research in the field of visual attention has focused on various concrete paradigms. However, as yet, there has been no clear demonstration of whether or not these paradigms are indeed measuring the same underlying construct. We collected a very large data set (nearly 1.3 million trials) to address this question. We…

This study investigated the role of imagery in the short-term retention of complex, visually presented movement sequences. Findings suggest that visual imagery may play a functional role in the free recall of modeled movements; however, there was no indication that imagery was involved in the retention of serial information.

Indicates that persons with different spatial visualization abilities enter different professions and that some sex differences exist with regard to spatial abilities. (RL)

The study investigated how performance on a spatial task in apparel design was influenced by training and strategical information processing style. The sample consisted of 278 undergraduate apparel design students from six universities in the U.S. Instruments used to collect data were the Apparel Spatial Visualization Test (ASVT) and the…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

A study was made to determine whether different methods of visual presentations would affect the retention rate of individuals with two distinct types of perception--visual and haptic. The visual type, according to a study by Viktor Lowenfeld in 1957, is marked by the following characteristics: (1) ability to see wholes, break them into visual…
