Visual scene memory and the guidance of saccadic eye movements
An unresolved question is how much information can be remembered from visual scenes when they are inspected by saccadic eye movements. Subjects used saccadic eye movements to scan a computer-generated scene, and afterwards, recalled as many objects as they could. Scene memory was quite good: it improved with display duration, it persisted over time long after the display was removed, and it con...
متن کاملThe visual component to saccadic compression.
Visual objects presented around the time of saccadic eye movements are strongly mislocalized towards the saccadic target, a phenomenon known as "saccadic compression." Here we show that perisaccadic compression is modulated by the presence of a visual saccadic target. When subjects saccaded to the center of the screen with no visible target, perisaccadic localization was more veridical than whe...
متن کاملImproving Visual Memory with Auditory Input
Can input in one sensory modality strengthen memory in a different sensory modality? To address this question, we asked participants to encode images presented in various locations (e.g., a depicted dog in the top left corner of the screen) while they heard spatially uninformative sounds. Some of these sounds matched the image (e.g., the word “dog” or a barking sound) while others did not. In a...
متن کاملHorizontal Saccadic Eye Movements to Visual and Auditory-Visual Double-Step Stimuli: Saccade Characteristics and Neural Input Estimations
Goal-oriented human saccades were recorded under double-step paradigm. The stimuli consisted of either visual or auditory-visual bi-sensory targets. Eye movement data were analyzed based on a 3rd-order linear horizontal saccadic eye movement model, where the inputs to the muscle were agonist and antagonist active-state tensions that were described by pulse-slide-step waveforms with a post inhib...
متن کاملThe Effect of Working Memory Rehabilitation on Visual Memory and Memory Span
Introduction: Age-related cognitive decline or cognitive aging is largely the result of structural and functional decline in specific areas of the brain, but lifestyle also contributes to this cognitive decline. The aim of this study was to investigate the effect of working memory rehabilitation on visual memory and memory span in ageing. Methods: This was a quasi-experimental study with pret...
