What pattern the eye sees best
The visibility of gratings improves with increasing stimulus area. This effect is usually interpreted as being due to physiological summation within the extent of the largest spatial filter and due to probability summation between the outputs of linear, independent filters beyond that range. It is generally assumed that this improvement is isotropic to the patch configuration. In contrast, the ...
متن کاملVisual Ecology: Coloured Fruit is What the Eye Sees Best
Trichromatic vision may have evolved as an aid to frugivory. This hypothesis is supported by the recent demonstration that the spatial characteristics of pictures containing fruit are particularly well matched to the abilities of the human visual system.
متن کاملReading What the Mind Thinks From How the Eye Sees.
Human eyes convey a remarkable variety of complex social and emotional information. However, it is unknown which physical eye features convey mental states and how that came about. In the current experiments, we tested the hypothesis that the receiver's perception of mental states is grounded in expressive eye appearance that serves an optical function for the sender. Specifically, opposing fea...
متن کاملEchocardiography in PICU: when the heart sees what is invisible to the eye.
OBJECTIVE Echocardiography has become an indispensable bedside diagnostic tool in the realm of pediatric intensive care units (PICU). It has proven to be an influential factor in the formula of clinical decision-making. This study aimed to delineate the impact of echocardiography on the management of critically ill pediatric patients in the PICU at Sultan Qaboos University Hospital, Oman. MET...
متن کاملThe Nose Smells What the Eye Sees Crossmodal Visual Facilitation of Human Olfactory Perception
Human olfactory perception is notoriously unreliable, but shows substantial benefits from visual cues, suggesting important crossmodal integration between these primary sensory modalities. We used event-related fMRI to determine the underlying neural mechanisms of olfactory-visual integration in the human brain. Subjects participated in an olfactory detection task, whereby odors and pictures we...
