Infants Rely More on Gaze Cues From Own-Race Than Other-Race Adults for Learning Under Uncertainty.

Differential experience leads infants to have perceptual processing advantages for own- over other-race faces, but whether this experience has downstream consequences is unknown. Three experiments examined whether 7-month-olds (range = 5.9-8.

Infants track the reliability of potential informants.

Across two eye-tracking experiments, we showed that infants are sensitive to the statistical reliability of informative cues and selective in their use of information generated by such cues. We familiarized 8-month-olds with faces (Experiment 1) or arrows (Experiment 2) that cued the locations of animated animals with different degrees of reliability. The reliable cue always cued a box containing an animation, whereas the unreliable cue cued a box that contained an animation only 25% of the time.

Ostensive signals support learning from novel attention cues during infancy.

Social attention cues (e.g., head turning, gaze direction) highlight which events young infants should attend to in a busy environment and, recently, have been shown to shape infants' likelihood of learning about objects and events.

Infants' selective attention to reliable visual cues in the presence of salient distractors.

With many features competing for attention in their visual environment, infants must learn to deploy attention toward informative cues while ignoring distractions. Three eye tracking experiments were conducted to investigate whether 6- and 8-month-olds (total N = 102) would shift attention away from a distractor stimulus to learn a cue-reward relation. While 8-month-olds showed evidence of increasingly selective attention toward the predictive cues, even when the distractors were highly salient, 6-month-olds shifted attention toward the predictive cues only when the distractors were equally (not more) engaging.

Learning to look: probabilistic variation and noise guide infants' eye movements.

Young infants have demonstrated a remarkable sensitivity to probabilistic relations among visual features (Fiser & Aslin, 2002; Kirkham et al., 2002). Previous research has raised important questions regarding the usefulness of statistical learning in an environment filled with variability and noise, such as an infant's natural world.
