Salley, Brenda; Panneton, Robin K.; Colombo, John – Infancy, 2013
The aim of this study was to examine the combined influences of infants' attention and use of social cues in the prediction of their language outcomes. This longitudinal study measured infants' visual attention on a distractibility task (11 months), joint attention (14 months), and language outcomes (word-object association, 14 months; MBCDI…

Colombo, John; Shaddy, D. Jill; Anderson, Christa J.; Gibson, Linzi J.; Blaga, Otilia M.; Kannass, Kathleen N. – Infancy, 2010
Despite the use of visual habituation over the past half century, relatively little is known about its underlying processes. We analyzed heart rate (HR) taken simultaneous with looking during infant-controlled habituation sessions collected longitudinally at 4, 6, and 8 months of age with the goal of examining how HR and HR-defined phases of…

The purpose of this experiment is to test whether shift flexibility in kindergarten children is a joint function of rule-usage and inhibition of attention. Sixty-six children were given either a distraction or facilitation condition in a computerized version of the dimensional change card sort task. In the distraction condition, the background of…

Young infants have repeatedly been shown to be slower than older infants to shift fixation from a midline stimulus to a peripheral stimulus. This is generally thought to reflect maturation of the neural substrates that mediate the disengagement of attention, but this developmental difference may also be attributable to young infants' slower…
