Increased freezing and decreased positive affect in postinstitutionalized children

Area of Science:

• Developmental Psychology
• Child Psychiatry
• Behavioral Science

Background:

• Early institutional neglect is linked to higher risks of internalizing disorders and increased fearfulness.
• Anxiety and depressive disorders in adopted children often emerge in adolescence, leaving early emotional responses understudied.
• The impact of institutional neglect on fear and behavioral inhibition in young adopted children remains unclear.

Purpose of the Study:

• To investigate whether young children adopted from institutional care exhibit heightened fear or behavioral inhibition.
• To compare the emotional responses of postinstitutionalized children with those reared in family environments.

Main Methods:

• Children adopted between 15-35 months from institutional care were assessed twice within their first year postadoption.
• A modified Laboratory Temperament Assessment Battery for Preschoolers exposed children to fear-eliciting and positive stimuli.
• Sessions were videotaped and coded by blinded observers to ensure objectivity.

Main Results:

• Postinstitutionalized children displayed increased freezing behavior during fear-eliciting stimuli.
• These children exhibited less positive affect in response to both fear and positive stimuli compared to non-adopted peers.
• Observed group differences in emotional responses remained consistent over the 6-month follow-up period.

Conclusions:

• Early institutional neglect leads to emotional biases in young children.
• These biases, characterized by heightened fear and reduced positive affect, align with the known risk for internalizing disorders.
• Findings suggest that early neglect has lasting effects on emotional regulation and behavioral patterns.
