BACKGROUND Individuals with attention-deficit/hyperactivity disorder (ADHD) are reported to manifest visual problems (including ophthalmological and color perception, particularly for blue-yellow stimuli), but findings are inconsistent. Accordingly, this study investigated visual function and color perception in adolescents with ADHD using color Visual Evoked Potentials (cVEP), which provides a...

The focus of this project was to modify the image feature extraction subsystem of the ImageRover system[11]. The subsystem was extended to use color and texture measures which more closely correspond to the human perception. The feature implemented for color is the color histogram in L u v color space. The texture measure implemented is 2D Wold decomposition, which incorporates the three most i...

OBJECTIVE To examine the relationship between measures of visual dysfunction and driving performance in persons with multiple sclerosis (MS). DESIGN Between-group comparison. SETTING All data were collected in an outpatient research setting. PARTICIPANTS Persons (N=66) with MS of the relapsing remitting type (26 self-reporting visual difficulties; 40 self-reporting no visual difficulties)...

How should we understand the relationship between conscious perception and action? Does an appeal to action have any place in an account of color experience? This essay aims to shed light on the first question by giving a positive response to the second. I consider two types of enactive approach to perceptual consciousness, and two types of account of color perception. Each approach to color pe...

Entitativity perception refers to the perception of a collection of individuals as a group. The authors propose 2 perceptual-inferential bases of entitativity perception. First, perceivers would expect a collection of individuals with similar physical traits to possess common psychological traits. Second, perceivers watching a group of individuals engage in concerted behavior would infer that t...

The present study examines how objective design factors of a website are linked to different facets of subjective aesthetic perception. Five online experiments based upon the screenshots of real-existing websites with a total of N = 194 participants were conducted to isolate and analyze the effects of two objective structural factors (vertical symmetry, visual complexity) and three objective co...

Four- and 7-month-old infants' perception of transparency was investigated with computer-generated achromatic or color displays depicting a semitransparent box occluding the center of a rod. Following habituation, infants viewed test displays consisting of either a two-color rod (corresponding to the habituation display's proximal characteristics) or a solid rod (corresponding to the distal cha...

Color filters humanity’s perception of the world and alters people’s relationships with their surroundings. It influences human perception, preference, and psychology throughout the lifespan. Color preferences appear in infants as young as three months old, and typically change with age. Some responses to color may be innate, and some may be learned from nature or culture. Cool hues are relaxan...

The study of color perception in humans is an important ongoing research which currently mainly relies on psychophysical studies. Most psychophysical studies are prune to limitations which can highly reduce the scalability and repeatability of their experiments, cause over-fitting, and fail to fully engage subjects in performing the given tasks. Gamification is becoming a popular approach in ob...
