Behavorial Assessment of Synesthetic Perception: Color Perception and Visual Imagery in Synesthesia
… examined vividness of visual mental imagery and color discrimination ability in synesthesia. It was hypothesized that participants with synesthesia would have higher overall scores on the Vividness of Visual Imagery Questionnaire (VVIQ) and participants with colored synesthetic experiences would …

Color Vision and its mechanisms in College students with Attention Deficit Hyperactivity Disorder
… children with ADHD have been found to exhibit color perception problems (particularly blue), which may be best explained by the `retinal dopaminergic hypothesis.' The hypothesis proposes that low dopamine in the central nervous system induces a hypo-dopaminergic state in the retina, which in …

Perception of Warm and Cool Colors
Warm and cool judgements of color perception are a fundamental aspect of visual experience. Very few studies have been conducted on this aspect of perception and only recently has this dimension of color perception gained traction in the visual sciences. In this work, I examine the nature of warm …

Entwurf und Modellierung von Multikanal-CMOS-Farbsensoren
Color image acquisition and image processing have become a key in modern data application. In order to provide high quality images, the field of accurate acquisition is most important in respect to all further processing steps. But a whole variety of current image sensors possess incorrect color …

A Connection Between Life and Art Through Light and Material
… title 16 Cones refers to the largest number of color receptive optical cones that any creature on earth has. The mantis shrimp has sixteen color receptive cones as compared to the three that humans have. It is impossible to fathom what visual experiences would be possible with more than five …

An Investigation of the Effects of Practice on Color Memory as a Function of Condition, Dimension and Color
… factorial design experiment that assessed color memory as a function of condition (practice with feedback, practice without feedback and no practice), dimension (hue, saturation and lightness) and color (red, yellow, green and blue). Attention was focused on the distinction between memory …

Speciation and the evolution of male breeding coloration in darters
… First, I quantified variation in male breeding coloration across multiple populations of E. caeruleum and E. spectabile using digital photography and image processing software. Male color traits in both species can be categorized as “blue” and “red” components, which are based on chromoprotein …

Avian diet and visual perception suggests avian predation selects for color pattern mimicry in bumble bees
… local bumble bee species tend to share the same color patterns. Statistical confirmation of these trends has resulted in the hypothesis that these similarity groups are Müllerian mimicry rings. Bumble bee color patterns are thought to convey protection from avian predators, thus creating …
