Chromatic contrast in luminance-defined images affects performance and neural activity during a shape classification task.
Models of object recognition generally emphasize the importance of luminance-defined shape. However, it is still not fully understood how color signals combine with luminance signals to affect object-related form processing. This electroencephalographic study aimed to examine the contribution of chromatic contrast by assessing its effects on the time course of shape-related processing. Particip...
متن کاملThe Effects of Age, Refractive Status, and Luminance on Pupil Size
PURPOSE Pupil size is critical for optimal performance of presbyopic contact lenses. Although the effect of luminance is well known, little information is available regarding other contributing factors such as aging and refractive status. METHODS The cohort population comprised 304 patients (127 male, 177 female) aged 18 to 78 years. Pupils were photographed at three controlled luminance leve...
متن کاملThe size and shape of the pupil in lightly anaesthetized cats as a function of luminance.
The S-shaped relation between pupil area and illumination is similar in this preparation to that of the human, with a mid-point just below 1 cd/m*. The range of pupii areas is. however, at least 10 times greater in the cat. ranging from more than 12Omm’ to less than I mm’. The following study of the size and shape of the cat’s pupil was undertaken for two reasons. First we wanted to verify that...
متن کاملTeacher Pupil and Task
designed to help practising teachers. It aims at introducing them to changes in outlook due to recent developments in psychology, particularly the need for "paying far more attention to the effects of group processes in the development of a balanced mature personality." (What I wonder is the exact meaning of "group processes" here?) The stress throughout is on social relationships inside and ou...
