形状知觉闪间位置知觉脑功能定位磁共振The present study, through fMRI, aimed at how the two visual pathways (the dorsal stream and the ventral stream) respond to form perception, spatial localization and a visuospatial task combining form perception and spatial localization. The findings were: form ...
It was also seen that both the proximal (c/deg) and the distal (c/picture) scales of spatial frequency measurement are involved in the identification process. 展开 关键词: Experimental/ visual perception/ visual identification spatial frequency filtering target identification filtered pictures/ A8732S...
Recent investigations of texture and motion perception suggest two early filtering stages: an initial stage of selective linear filtering followed by recti... A Sutter,G Sperling,C Chubb - 《Vision Research》 被引量: 300发表: 1995年 The role of spatial disparity and hemifields in audio-visual ...
Here, we leverage population receptive field models to parameterize fMRI activity in human visual cortex during spatial memory retrieval. Though retinotopic organization is present during both perception and memory, large systematic differences in tuning are also evident. Whereas there is a three-fold ...
This study examined how spatial working memory and visual (object) working memory interact, focusing on two related questions: First, can these systems function independently from one another? Second, under what conditions do they operate together? In a dual-task paradigm, participants attempted to ...
Thirty-six human subjects, facing a panel of 100 loud-speakers, were requested to match sounds outlining geometrical and alphabetical patterns with visual pattern choices, which were given to them on a folder. The listeners' correct responses were found to be above chance. Geometrical patterns were...
Despite the large interest in the human ability to perceive space present in neuroscience, cognitive science and psychology, as well as philosophy of mind,
If a target frequently appears in a specific area of the visual display, individuals can learn this statistical regularity and prioritize their spatial attention toward the most frequent target location9,10,11,12. Location probability learning is a form of location-based learning and is independent ...
Receptive field (RF) size and preferred spatial frequency (SF) vary greatly across the primary visual cortex (V1), increasing in a scale invariant fashion with eccentricity. Recent studies reveal that preferred SF also forms a fine-scale periodic map. A
The visual system is therefore faced with the problem of linking the separate edge fragments that belong to the same object into a single unit. That a linking process takes place in the visual system may be observed directly in phenomena like illusory contours (Kanizsa, 1979; Petry and Meyer,...
