Murphy, Eric R.; Norr, Megan; Strang, John F.; Kenworthy, Lauren; Gaillard, William D.; Vaidya, Chandan J. – Journal of Autism and Developmental Disorders, 2017
We examined spontaneous attention orienting to visual salience in stimuli without social significance using a modified Dot-Probe task during functional magnetic resonance imaging in high-functioning preadolescent children with Autism Spectrum Disorder (ASD) and age- and IQ-matched control children. While the magnitude of attentional bias (faster…

Collisson, Beverly Anne; Grela, Bernard; Spaulding, Tammie; Rueckl, Jay G.; Magnuson, James S. – Developmental Science, 2015
We investigated whether preschool children with specific language impairment (SLI) exhibit the shape bias in word learning: the bias to generalize based on shape rather than size, color, or texture in an object naming context ("This is a wek; find another wek") but not in a non-naming similarity classification context ("See this?…

Sweeney, Mary M.; Rass, Olga; DiClemente, Cara; Schacht, Rebecca L.; Vo, Hoa T.; Fishman, Marc J.; Leoutsakos, Jeannie-Marie S.; Mintzer, Miriam Z.; Johnson, Matthew W. – Journal of Child & Adolescent Substance Abuse, 2018
Adolescent cannabis use is associated with working memory impairment. The present randomized controlled trial assigned adolescents ages 14 to 21 enrolled in cannabis use treatment to receive either working memory training (experimental group) or a control training (control group) as an adjunctive treatment. Cognitive function, drug use, and other…

Clifford, Alexandra; Franklin, Anna; Holmes, Amanda; Drivonikou, Vicky G.; Ozgen, Emre; Davies, Ian R. L. – Brain and Cognition, 2012
Category training can induce category effects, whereby color discrimination of stimuli spanning a newly learned category boundary is enhanced relative to equivalently spaced stimuli from within the newly learned category (e.g., categorical perception). However, the underlying mechanisms of these acquired category effects are not fully understood.…

Martinez-Borreguero, Guadalupe; Perez-Rodriguez, Angel Luis; Suero-Lopez, Maria Isabel; Pardo-Fernandez, Pedro Jose – International Journal of Science Education, 2013
We study the misconceptions about colour that most people hold, determining the general phenomenological laws that govern them. Concept mapping was used to combat the misconceptions which were found in the application of a test specifically designed to determine these misconceptions, while avoiding the possible misleading inductions that could…

Rich, Anina N.; Mattingley, Jason B. – Cognition, 2010
Mechanisms of selective attention exert a powerful influence on visual perception. We examined whether attentional selection is necessary for generation of the vivid colours experienced by individuals with grapheme-colour synaesthesia. Twelve synaesthetes and matched controls viewed rapid serial displays of nonsense characters within which were…

Van Herwegen, Jo; Farran, Emily; Annaz, Dagmara – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Raven's Coloured Progressive Matrices (RCPM) is a standardised test that is commonly used to obtain a non-verbal reasoning score for children. As the RCPM involves the matching of a target to a pattern it is also considered to be a visuo-spatial perception task. RCPM is therefore frequently used in studies in Williams Syndrome (WS), in order to…

Faraci, Marie Elaine – ProQuest LLC, 2009
The problem. The purpose of this study was to examine the effect of the Irlen[R] method's use of colored overlays on the reading achievement of 3rd-grade students who were identified as having Scotopic Sensitivity Syndrome/Irlen[R] Syndrome. Method. This was a true experimental, pre-test, post-test design. The Irlen[R] overlay, either present…

Twyman, Alexandra; Friedman, Alinda; Spetch, Marcia L. – Developmental Psychology, 2007
We used a reference memory paradigm to examine whether 4- and 5-year-old children could be trained to use landmark features to relocate targets after disorientation. In Experiment 1, half of the children were pretrained in a small equilateral triangle-shaped room. Each of the three walls was a different color, and the target was always in the…

Jover, Julio Lillo; Moreira, Humberto – Psicologica: International Journal of Methodology and Experimental Psychology, 2005
Four experiments evaluated AMLA temporal version accuracy to measure relative luminosity in people with and without color blindness and, consequently, to provide the essential information to avoid poor figure-background combinations in any possible "specific screen-specific observer" pair. Experiment 1 showed that two very different…

Ludlow, Amanda K.; Wilkins, Arnold J.; Heaton, Pam – Journal of Autism and Developmental Disorders, 2006
Abnormalities of colour perception in children with autistic spectrum disorders have been widely reported anecdotally. However, there is little empirical data linking difficulties in colour perception with academic achievement. The Wilkins Rate of Reading Test was administered with and without "Intuitive Coloured Overlays" to 19 children with…
