Hagmann, Carl Erick; Wyble, Bradley; Shea, Nicole; LeBlanc, Megan; Kates, Wendy R.; Russo, Natalie – Journal of Autism and Developmental Disorders, 2016
Enhanced perception may allow for visual search superiority by individuals with Autism Spectrum Disorder (ASD), but does it occur over time? We tested high-functioning children with ASD, typically developing (TD) children, and TD adults in two tasks at three presentation rates (50, 83.3, and 116.7 ms/item) using rapid serial visual presentation.…

Morales, Julia; Calvo, Alejandra; Bialystok, Ellen – Journal of Experimental Child Psychology, 2013
Two studies are reported comparing the performance of monolingual and bilingual children on tasks requiring different levels of working memory. In the first study, 56 5-year-olds performed a Simon-type task that manipulated working memory demands by comparing conditions based on two rules and four rules and manipulated conflict resolution demands…

Juttner, Martin; Wakui, Elley; Petters, Dean; Kaur, Surinder; Davidoff, Jules – Developmental Psychology, 2013
Three experiments assessed the development of children's part and configural (part-relational) processing in object recognition during adolescence. In total, 312 school children aged 7-16 years and 80 adults were tested in 3-alternative forced choice (3-AFC) tasks. They judged the correct appearance of upright and inverted presented familiar…

Crookes, Kate; McKone, Elinor – Cognition, 2009
Historically, it was believed the perceptual mechanisms involved in individuating faces developed only very slowly over the course of childhood, and that adult levels of expertise were not reached until well into adolescence. Over the last 10 years, there has been some erosion of this view by demonstrations that all adult-like behavioural…

Zaitchik, Deborah; Walker, Caren; Miller, Saul; LaViolette, Pete; Feczko, Eric; Dickerson, Bradford C. – Neuropsychologia, 2010
By age 2, children attribute referential mental states such as perceptions and emotions to themselves and others, yet it is not until age 4 that they attribute representational mental states such as beliefs. This raises an interesting question: is attribution of beliefs different from attribution of perceptions and emotions in terms of its neural…

Benoit, Laurent; Lehalle, Henri; Jouen, Francois – Cognitive Development, 2004
Two alternative hypotheses can be used to explain how young children acquire the cardinal meaning of small-number words. The first stresses the role of counting and predicts better performance when the items are presented in succession. The second considers the role of subitizing and predicts better performance when the items are presented…

Langstaff, Anne L.; Volkmor, Cara B. – 1971
A model for sequencing tasks in the area of visual perception was developed. This paper reports an attempt to validate the structure of the model. The performance of 50 normal preschool children on a 47 item test was studied. The results obtained support the use of the model as a framework for developing visual perception tasks. (Author)

Brodeur, Darlene A. – Cognitive Development, 2004
Children (ages 5, 7, and 9 years) and young adults completed two visual attention tasks that required them to make a forced choice identification response to a target shape presented in the center of a computer screen. In the first task (high correlation condition) each target was flanked with the same distracters on 80% of the trials (valid…

Swinton, Spencer S.; And Others – 1977
The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…
