The Stability of Visual Habituation during the First Year of Life.
Peer reviewed Peer reviewed
Colombo, John; And Others – Child Development, 1987
The short-term reliability and long-term stability of visual habituation and dishabituation in infancy were assessed in a sample of 186 infants from four age groups (3-, 4-, 7- and 9-month-olds) seen for two within-age sessions, and in a sample of 69 infants seen longitudinally at 3, 4, 7, and 9 months of age.

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…

Heart Rate-Defined Phases of Attention, Look Duration, and Infant Performance in the Paired-Comparison Paradigm.
Peer reviewed Peer reviewed
Colombo, John; Richman, W. Allen; Shaddy, D. Jill; Greenhoot, Andrea Follmer; Maikranz, Julie M. – Child Development, 2001
Presented paired-comparison familiarization-novelty recognition task to 4-month-olds. Found that peak look duration during pretest and familiarization periods predicted recognition performance. Recognition was unaffected by choice-trial length. Longer gaze durations during pretest and familiarization were associated with more time in heart…
