Evaluating the Influence of ipRGCs on Color Discrimination [PDF]
Journal of Imaging, 2022 To investigate the influence of intrinsically photosensitive retinal ganglion cells (ipRGCs) on color discrimination, it is necessary to create two metameric light stimuli (metameric ipRGC stimuli) with the same amount of cone and rod stimulation, but ...

Association between cognition and color discrimination among Lebanese patients with schizophrenia [PDF]
BMC Psychiatry, 2022 Background Patients with schizophrenia (SCZ) exhibit poorer color discrimination than normal individuals. Although retinal abnormalities, as well as cortical and subcortical alterations, found in patients with SCZ have been suggested to cause this poor ...

Sex differences in color discrimination and serial reversal learning in mollies and guppies [PDF]
Curr Zool, 2019 Behavioral flexibility provides an individual with the ability to adapt its behavior in response to environmental changes. Studies on mammals, birds, and teleosts indicate greater behavioral flexibility in females.

Color discrimination thresholds in a cichlid fish: Metriaclima benetos
J Exp Biol, 2019 Color vision is essential for animals as it allows them to detect, recognize and discriminate between colored objects. Studies analyzing color vision require an integrative approach, combining behavioral experiments, physiological models and quantitative

Psychophysics of the hoverfly: categorical or continuous color discrimination? [PDF]
Curr Zool, 2019 There is increasing interest in flies as potentially important pollinators. Flies are known to have a complex visual system, including 4 spectral classes of photoreceptors that contribute to the perception of color. Our current understanding of how color

“Distribution of dominant wavelengths predicts jackdaw (Corvus monedula) color discrimination performance” [PDF]
Frontiers in PhysiologyColor vision is an important perceptual ability in most species and a crucial capacity underlying any cognitive task working with color stimuli. Birds are known for their outstanding vision and tetrachromacy. Two jackdaws were trained to indicate whether
