On the distinction between fear and wariness

Area of Science:

• Developmental Psychology
• Child Behavior Studies
• Social-Emotional Development

Background:

• Understanding the origins of avoidant behaviors in early childhood is crucial for developmental trajectories.
• Previous research has not fully delineated the distinct mechanisms underlying infant avoidant reactions.

Purpose of the Study:

• To investigate and differentiate the mechanisms mediating avoidant reactions in human infants during their second year of life.
• To examine the long-term predictive validity of these mechanisms on social orientations at age 3 1/2.

Main Methods:

• Longitudinal observation of 40 infants across their second year in mildly challenging situations.
• Repeated follow-up assessments at age 3 1/2.
• Covariance pattern analysis of repeated measurements to identify distinct mechanisms.

Main Results:

• Two independent sources of individual differences in avoidant mechanisms were identified: 'wariness' (unfamiliarity) and 'fear' (post-challenge).
• Behaviors stemming from prior experience (fear) predicted future social orientations.
• Initial wariness did not significantly predict future social orientations.

Conclusions:

• Infant avoidant reactions comprise distinct 'wariness' and 'fear' mechanisms, each representing an independent individual difference.
• The development of fear-based avoidance is a significant predictor of later social behavior and orientation.
• Early wariness, while distinct, shows limited predictive power for future social development compared to fear.
