“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

Shifts in Color Discrimination during Early Pregnancy [PDF]
Evolutionary Psychology, 2012 The present study explores two hypotheses: a) women during early pregnancy should experience increased color discrimination ability, and b) women during early pregnancy should experience shifts in subjective preference away from images of foods that ...

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 ...

Effect of the Decrease in Luminance Noise Range on Color Discrimination of Dichromats and Trichromats [PDF]
Frontiers in Behavioral Neuroscience, 2018 Color vision assessment can be done using pseudoisochromatic stimuli, which has a luminance noise to eliminate brightness differences between the target and background of the stimulus.

Color Discrimination with Broadband Photoreceptors [PDF]
Current Biology, 2013 Color vision is commonly assumed to rely on photoreceptors tuned to narrow spectral ranges. In the ommatidium of Drosophila, the four types of so-called inner photoreceptors express different narrow-band opsins. In contrast, the outer photoreceptors have a broadband spectral sensitivity and were thought to exclusively mediate achromatic vision.Using ...
