Existing research on spatial ability recognizes the critical role played by spatial visualization and mental rotation. Recent evidence suggests that external visualization and manipulation can boost spatial thinking. The virtual environment provides an exciting opportunity so that many spatial ability training tasks based on reading printed…

Visual imagery and mental reconstruction of scenes are considered core components of episodic memory retrieval. Individuals with absent visual imagery (aphantasia) score lower on tests of autobiographical memory, suggesting that aphantasia may be associated with differences in episodic and associative processing. In this online study, we tested…

Individuals with developmental disabilities demonstrate deficits in intellectual and adaptive functioning that can include difficulty describing past events; accurate recall may be improved by learning to engage in precurrent, or problem solving, behavior. Visual imagining is a problem-solving strategy that involves seeing in the absence of the…

Ancient as well as modern writers have promoted the idea that bizarre images enhance memory. Research has documented bizarreness effects, with one standard technique finding that sentences describing unusual, implausible, or bizarre scenarios are better remembered than sentences describing plausible, every day, or common scenarios. Not…

Undergraduate organic chemistry students, as they study conformational analysis and stereochemistry, frequently have trouble manipulating three-dimensional structures on a two-dimensional page or screen. The inability to accurately convert three-dimensional bond-line representations into Fischer projections is one example of this. While some…

Purpose: The purpose was (1) to test a new version of a mental rotation task (MRT), which assesses mental rotation abilities of men and women for sport-specific items, and (2) to investigate potential differences in MRT performance, which are based on athletic expertise. Methods: Eighty-eight basketball experts (42 females) and 123 novices (64…

This study proposes a software system for determining gaze patterns in on-screen testing. The system applies machine learning techniques to eye-movement data obtained from an eye-tracking device to categorize students according to their gaze behavior pattern while solving an on-screen test. These patterns are determined by converting eye movement…

At the highest level, this dissertation is a case study on how bias can become encoded into the tools used to measure a construct and into the very definition of the construct itself. In this case, the construct is spatial ability. This dissertation focuses on the validity and accuracy of spatial tests and illuminates gender bias that is…

Reasoning is handled as a basic process skill in mathematics teaching. When the literature was examined, it was seen that many types of reasoning related to mathematics education were mentioned. In the present study, it was focused on visual reasoning, which is one of the types of reasoning and also used in different research areas. The purpose of…

The present study was to explore whether dynamic visualizations enriched with visuospatial cues can optimize learners' cognitive processing of mechanical systems. The animated conditions and cueing patterns were the independent variables with an attempt to investigate their impacts on retention and transfer tests. Either dynamic or static…

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…

This study compares the experts and the novices to investigate their information processing in dealing with the different degrees of recognition of shape-match stimulus by measuring the event-related potentials (ERPs). ERPs were recorded while 20 designers and 20 novices made shape-match judgments for table and chair sets. All of the tables were…
