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…

Coldren, Jeffrey T.; Colombo, John – Infant and Child Development, 2009
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…

Coldren, Jeffrey T.; Colombo, John – Monographs of the Society for Research in Child Development, 1994
In three experiments, nine-month-old infants were trained to fixate on a particular feature in a pair of stimuli that varied along three dimensions. In a fourth experiment, infants were trained to fixate on a stimulus compound until reaching a learning criterion. Infants' discrimination learning under these conditions implied an ability to attend…

Shaddy, D. Jill; Colombo, John – Infancy, 2004
This study examined 4- and 6-month-olds' responses to static or dynamic stimuli using behavioral and heart-rate-defined measures of attention. Infants looked longest to dynamic stimuli with an audio track and least to a static stimulus that was mute. Overall, look duration declined with age to the different stimuli. The amount of time spent in…

Colombo, John; And Others – Cognitive Development, 1995
Investigates the dominance of global versus local visual properties in four-month-old infants as a function of individual differences in fixation duration. Suggests that long-looking infants process visual information more slowly than short-looking infants, and there may be qualitative differences in the manner in which the two groups of infants…
