Insights
Infants at 14 months use attentional cues, not emotional cues, to predict actions. While they can use emotions for social referencing, they don't yet predict behavior based on them.
Area of Science:
- Developmental psychology
- Infant cognition
- Social cognition
Background:
- Previous research indicated 12-14 month olds use emotional and attentional cues to predict actions.
- Prior studies used only positive emotions, conflating attention and emotion effects.
- The role of emotional cues in action prediction remained unclear.
Purpose of the Study:
- To investigate if 14-month-old infants use emotional cues to predict a person's actions.
- To differentiate the predictive power of emotional versus attentional cues.
- To clarify the developmental trajectory of using emotional cues for action prediction.
Main Methods:
- A looking-time paradigm was employed with 14-month-old infants.
- Both positive and negative emotional cues were presented.
- Infants' looking times were measured to infer predictive capabilities.
Main Results:
- Infants utilized attentional cues to predict actions.
- Infants did not use emotional cues as predictors of actions.
- Findings suggest a developmental lag in using emotion for action prediction.
Conclusions:
- 14-month-olds do not robustly predict others' actions using emotional cues.
- Infants can use emotional cues for social referencing, but not yet for action prediction.
- This highlights a specific developmental milestone in social cognition.
Abstract:
Phillips et al. (2002) suggest that by 12-14 months, infants can use a person's emotional and attentional cues to predict that person's actions. However, this work was conducted using only positive emotions, which is problematic because attention and positive emotions lead to the same prediction about a person's actions, thus leaving unclear whether infants made predictions based upon attention and emotion or attention alone. To get around this problem, we used both positive and negative emotions in a looking-time paradigm to investigate whether 14-month-old infants can use emotional cues to predict a person's actions. The findings suggest that infants used attentional but not emotional cues as predictors. We argue that while 14-month-olds can use another person's emotion cues to modify their own behavior (as in social referencing situations), they do not yet use them robustly to predict the other's behavior.
