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…

Individual Differences in Infant Visual Attention: Are Short Lookers Faster Processors or Feature Processors?
Peer reviewed Peer reviewed
Colombo, John; And Others – Child Development, 1991
Four experiments tested four month olds on visual discrimination tasks. As the time allotted to solve these problems was shortened, infants who looked at stimuli for a short amount of time performed better than other infants, indicating that performance superiority was attributable to speed of processing.

Individual and Developmental Differences in Disengagement of Fixation in Early Infancy.
Peer reviewed Peer reviewed
Frick, Janet E.; Colombo, John; Saxon, Terrill F. – Child Development, 1999
Investigated whether individual and developmental differences in look duration were correlated with latency to disengage fixation from a visual stimulus for 3- and 4-month olds. Found that look duration was correlated with disengagement latency. Three-month olds showed slower latencies than 4-month olds. Long-looking infants showed greater…

Long- and Short-Looking Infants' Recognition of Symmetrical and Asymmetrical Forms.
Peer reviewed Peer reviewed
Stoecker, Jennifer J.; Colombo, John; Frick, Janet E.; Allen, Jennifer Ryther – Journal of Experimental Child Psychology, 1998
Three experiments examined the hypothesis that individual differences in look-duration during infancy covary with different modes of visual intake and encoding, with longer look-durations reflecting encoding based on prolonged inspection of local visual properties, and briefer durations reflecting encoding based on a global, or global-to-local…

Individual Differences in Infant Fixation Duration: Dominance of Global versus Local Stimulus Properties.
Peer reviewed Peer reviewed
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…

On the Neural Mechanisms Underlying Developmental and Individual Differences in Visual Fixation in Infancy: Two Hypotheses.
Peer reviewed Peer reviewed
Colombo, John – Developmental Review, 1995
Examines the potential contribution of different neural systems to developmental change in the duration of visual fixation, and the individual differences in that variable that are predictive of subsequent cognitive function. Presents hypotheses concerning two specific and independent neural systems and how they might contribute to individual and…
