Mallin, Brittany M.; Richards, John E. – Infancy, 2012
This study examined the effect of attention in young infants on the saccadic localization of dynamic peripheral stimuli presented on complex and interesting backgrounds. Infants at 14, 20, and 26 weeks of age were presented with scenes from a Sesame Street movie until fixation on a moving character occurred and then presented with a second segment…

Morgante, James D.; Zolfaghari, Rahman; Johnson, Scott P. – Infancy, 2012
Infant eye tracking is becoming increasingly popular for its presumed precision relative to traditional looking time paradigms and potential to yield new insights into developmental processes. However, there is strong reason to suspect that the temporal and spatial resolution of popular eye tracking systems is not entirely accurate, potentially…

Shafto, Carissa L.; Conway, Christopher M.; Field, Suzanne L.; Houston, Derek M. – Infancy, 2012
Research suggests that nonlinguistic sequence learning abilities are an important contributor to language development (Conway, Bauernschmidt, Huang, & Pisoni, 2010). The current study investigated visual sequence learning (VSL) as a possible predictor of vocabulary development in infants. Fifty-eight 8.5-month-old infants were presented with a…

Cantlon, Jessica F.; Brannon, Elizabeth M. – Infancy, 2006
We investigated how within-stimulus heterogeneity affects the ability of rhesus monkeys to order pairs of the numerosities 1 through 9. Two rhesus monkeys were tested in a touch screen task where the variability of elements within each visual array was systematically varied by allowing elements to vary in color, size, shape, or any combination of…

Reznick, J. Steven; Morrow, Judy D.; Goldman, Barbara Davis; Snyder, Jessica – Infancy, 2004
We used an optimized configuration of the delayed-response task to explore the ability of young infants to remember which of 2 locations was correct across 12 trials after a 1- to 2-sec delay. Performance improved with age, particularly after 5.5 months. These findings suggest an onset of appreciable working memory for many infants in the middle…

Gredeback, Gustaf; von Hofsten, Claes – Infancy, 2004
Infants' ability to track temporarily occluded objects that moved on circular trajectories was investigated in 20 infants using a longitudinal design. They were first seen at 6 months and then every 2nd month until the end of their 1st year. Infants were presented with occlusion events covering 20% of the target's trajectory (effective occlusion…
