Temporal seeing is a mode of visual perception that interrupts the spatial bias we bring to visual literacy practices. Although an image only captures one moment in time, there are multiple spatioanalytical tools we can use to consider any image. Spatial literacy, which is the practice of analyzing objects through their properties in space, tends…

While visual working memory has a short lifetime, residual representations can persist and disrupt currently maintained information. This phenomenon is known as proactive interference (PI), and the present study investigated whether the representations underpinning item-specific PI lose details over time. This would be expected if the memories…

Natural environments provide a rich spatiotemporal context that allows for visual objects to be differentiated based on different types of information: their absolute or relative spatial or temporal coordinates, or their ordinal positions in a spatial or temporal sequence. Here, we investigated which spatial and temporal properties are…

Longer free time between presentation of verbal list items often leads to better immediate serial recall. The present series of three experiments demonstrates that this beneficial effect of time is more general than has been known: It is found for verbal items presented visually and auditorily (Experiments 1 and 2), and also when people engage in…

The present study investigated (a) whether the perceived cognitive load was different when geometry problems with various levels of configuration comprehension were solved and (b) whether eye movements in comprehending geometry problems showed sources of cognitive loads. In the first investigation, three characteristics of geometry configurations…

An important issue for understanding visual perception in autism concerns whether individuals with this neurodevelopmental disorder possess an advantage in processing local visual information, and if so, what is the nature of this advantage. Perception of movement speed is a visual process that relies on computation of local spatiotemporal signals…

It is well established that visual search becomes harder when the similarity between target and distractors is increased and the similarity between distractors is decreased. However, in models of visual search, similarity is typically treated as a static, time-invariant property of the relation between objects. Data from other perceptual tasks…

The visual system groups image elements that belong to an object and segregates them from other objects and the background. Important cues for this grouping process are the Gestalt criteria, and most theories propose that these are applied in parallel across the visual scene. Here, we find that Gestalt grouping can indeed occur in parallel in some…

Visual stress is a perceptual dysfunction that appears to affect how information is processed as it passes from the eyes to the brain. Photophobia, visual resolution, restricted focus, sustaining focus, and depth perception are all components of visual stress. Because visual stress affects what is perceived by the eye, students with this disorder…

Schizophrenia may be associated with a fundamental disturbance in the temporal coordination of information processing in the brain, leading to classic symptoms of schizophrenia such as thought disorder and disorganized and contextually inappropriate behavior. Despite the growing interest and centrality of time-dependent conceptualizations of the…

When a moving object abruptly disappears, this profoundly influences its localization by the visual system. In Experiment 1, 2 aligned objects moved across the screen, and 1 of them abruptly disappeared. Observers reported seeing the objects misaligned at the time of the offset, with the continuing object leading. Experiment 2 showed that the…

This research is an effort to best utilize the interactive anatomical images for instructional purposes based on cognitive load theory. Three studies explored the differential effects of three computer-based instructional strategies that use anatomical cross-sections to enhance the interpretation of radiological images. These strategies include:…

The effects of black and white and color illustrations on student achievement were studied to investigate the relationships between cognitive styles and instructional design. Field dependence (FD) and field independence (FI) were chosen as the cognitive style variables. Subjects were 85 freshman students in the Iowa State University Psychology…

Children referred for evaluation of learning impairment (n=100) and 243 typical children were evaluated on a visual filtering task. With each additional processing demand, response times increased disproportionately for children with learning impairments. Overall response time predicted academic skills and cognitive ability, but was more strongly…
