Patrick Jost; Elias Berchtold; Sebastian Rangger – International Association for Development of the Information Society, 2024
One of the world's most famous pyramids is not located in Egypt but is on a music album cover by the band Pink Floyd. However, not a pyramid but a prism, the iconic image of a beam of light turning into a rainbow is a powerful symbol that captures the complexities of colour perception across cultures and individuals. This study examines how…

Peer reviewed Peer reviewed

Wilkinson, Krista M.; Gilmore, Rick; Qian, Yiming – Journal of Speech, Language, and Hearing Research, 2022
Purpose: Aided augmentative and alternative communication (AAC) displays are often designed as symmetrical row--column grids, with each square in the grid containing a symbol. To maximize vocabulary on displays, symbols are often placed close to one another, and background color cuing is used to signal/differentiate symbols across different…

Cognitive function, drug use, and other…

Facilitation and Inhibition Effects in Visual Selective Attention Processes of Individuals with and without Mental Retardation.
Cha, Kyeong-Ho; Merrill, Edward C. – American Journal on Mental Retardation, 1993
Adolescents identified letters presented to them on the basis of color. Subjects (n=20) with mental retardation exhibited facilitation when the target was identical to the target on the preceding trial but did not exhibit inhibition when it had been a distractor on the preceding trial. Inefficient suppression processes may result in performance…

The Concept of Dimension in Research on Children's Learning.
Peer reviewed Peer reviewed
Offenbach, Stuart I. – Monographs of the Society for Research in Child Development, 1983
Results of four related studies revealed (1) a trend toward better differentiation of the color attribute from four years through college-age; and (2) a possible stage of development, occurring before children can organize stimulus values conceptually or multidimensionally, in which they are able to organize or "dimensionalize" stimulus values…

Visual Preferences of Students with Profound Mental Retardation and Healthy, Full-Term Infants.
Peer reviewed Peer reviewed
Buhrow, Melissa; Bradley-Johnson, Sharon – Research in Developmental Disabilities, 2003
Thirty students (ages 3-20) with profound mental retardation and 30 healthy, full-term infants (5-8 months) were shown 12 patterned stimuli, three times each. Both groups looked significantly longer at face patterns than other patterns. However, the students with mental retardation looked longer at black and white patterns than colored patterns,…
