Insights
Infants pay more attention to a person's face as they see the same action demonstrated repeatedly. Familiarity with objects influences infant attention, but not familiarity with the presenter.
Area of Science:
- Developmental Psychology
- Cognitive Neuroscience
- Infant Visual Attention
Background:
- Infants exhibit early visual preferences for faces.
- Infants possess observational learning capabilities.
- Understanding how infant attention shifts with familiarity is crucial.
Purpose of the Study:
- To investigate changes in infant visual attention as familiarity with a person and demonstrated actions increases.
- To analyze the relationship between face-to-action ratio and repeated exposure to novel actions.
Main Methods:
- Tracking visual attention patterns in 12- and 16-month-old infants (n=90).
- Infants watched videos of an adult demonstrating novel actions with objects three times.
- Calculating a face-to-action ratio for visual attention across repetitions.
Main Results:
- The face-to-action ratio significantly increased with each repetition of the action.
- Infant attention shifted towards the face relative to the action upon repeated demonstrations.
- Object familiarity influenced the face-to-action ratio in 12-month-olds.
Conclusions:
- Infant attention dynamically adjusts to increasing familiarity with demonstrated actions.
- Early face preferences are modulated by repeated action observation in a dynamic context.
- Object familiarity, not presenter familiarity, impacts infant attention allocation.
Abstract:
Infants' early visual preferences for faces, and their observational learning abilities, are well-established in the literature. The current study examines how infants' attention changes as they become increasingly familiar with a person and the actions that person is demonstrating. The looking patterns of 12- (n = 61) and 16-month-old infants (n = 29) were tracked while they watched videos of an adult presenting novel actions with four different objects three times. A face-to-action ratio in visual attention was calculated for each repetition and summarized as a mean across all videos. The face-to-action ratio increased with each action repetition, indicating that there was an increase in attention to the face relative to the action each additional time the action was demonstrated. Infant's prior familiarity with the object used was related to face-to-action ratio in 12-month-olds and initial looking behavior was related to face-to-action ratio in the whole sample. Prior familiarity with the presenter, and infant gender and age, were not related to face-to-action ratio. This study has theoretical implications for face preference and action observations in dynamic contexts.
