Top row: Still images of rotating objects shown during habituation. Infants were habituated to one of the two objects. Bottom row: Objects shown after habituation. Infants viewed both objects on alternating trials. See text for details.

Left, top: Velcro mittens worn by infants in the object exploration task. Left, bottom: The two objects presented to infants during the object exploration task. Right: An infant participating in the object exploration task. (The infant’s parent provided written informed consent to publish this image).

Posthabituation looking times.
Posthabituation Novelty Preference scores for individual infants in the Mittens First condition (left two columns) and the Mittens Second condition (right two columns). Data for females and males are plotted separately. The dotted line indicates chance performance.

Descriptive statistics of novelty preferences and object exploration measures by condition and sex (Mean (SD)), and Across all Infants (Overall).
Fig 4.
Relations between object exploration and looking times.
Total Engagement is plotted against Posthabituation Novelty Preferences for individual infants in the Mittens First and Mittens Second conditions. There was a positive relation between measures for the Mittens First condition (dark symbols, solid trendline) but not for the Mittens Second condition (light symbols, dotted trendline).
