Developmental Changes in the Discrimination of Dynamic Human Actions in Infancy
Peer reviewed Peer reviewed
Direct linkDirect link
Loucks, Jeff; Sommerville, Jessica A. – Developmental Science, 2012
Recent evidence suggests that adults selectively attend to features of action, such as how a hand contacts an object, and less to configural properties of action, such as spatial trajectory, when observing human actions. The current research investigated whether this bias develops in infancy. We utilized a habituation paradigm to assess…

The Role of Color Cues in Facilitating Accurate and Rapid Location of Aided Symbols by Children with and without Down Syndrome
Peer reviewed Peer reviewed
Direct linkDirect link
Wilkinson, Krista; Carlin, Michael; Thistle, Jennifer – American Journal of Speech-Language Pathology, 2008
Purpose: This research examined how the color distribution of symbols within a visual aided augmentative and alternative communication array influenced the speed and accuracy with which participants with and without Down syndrome located a target picture symbol. Method: Eight typically developing children below the age of 4 years, 8 typically…

Infants' Use of Synchronized Visual Information to Separate Streams of Speech
Peer reviewed Peer reviewed
Direct linkDirect link
Hollich, George; Newman, Rochelle S.; Jusczyk, Peter W. – Child Development, 2005
In 4 studies, 7.5-month-olds used synchronized visua-lauditory correlations to separate a target speech stream when a distractor passage was presented at equal loudness. Infants succeeded in a segmentation task (using the head-turn preference procedure with video familiarization) when a video of the talker's face was synchronized with the target…

Infants' Enumeration of Actions: Numerical Discrimination and Its Signature Limits
Peer reviewed Peer reviewed
Direct linkDirect link
Wood, Justin N.; Spelke, Elizabeth S. – Developmental Science, 2005
Are abstract representations of number--representations that are independent of the particular type of entities that are enumerated--a product of human language or culture, or do they trace back to human infancy? To address this question, four experiments investigated whether human infants discriminate between sequences of actions (jumps of a…

Understanding Emotions from Standardized Facial Expressions in Autism and Normal Development
Peer reviewed Peer reviewed
Direct linkDirect link
Castelli, Fulvia – Autism: The International Journal of Research and Practice, 2005
The study investigated the recognition of standardized facial expressions of emotion (anger, fear, disgust, happiness, sadness, surprise) at a perceptual level (experiment 1) and at a semantic level (experiments 2 and 3) in children with autism (N= 20) and normally developing children (N= 20). Results revealed that children with autism were as…

The Ability of Visually Impaired Children to Read Expressions and Recognize Faces.
Peer reviewed Peer reviewed
Ellis, H. D.; And Others – Journal of Visual Impairment and Blindness, 1987
Seventeen visually impaired children, aged 7-11 years, were compared with sighted children on a test of facial recognition and a test of expression identification. The visually impaired children were less able to recognize faces successfully but showed no disadvantage in discerning facial expressions such as happiness, anger, surprise, or fear.…
