Psychosocial deprivation and receptive language ability: a two-sample study.

Area of Science:

• Developmental Psychology
• Child Language Acquisition
• Longitudinal Studies

Background:

• Early caregiving quality significantly influences children's language experiences.
• The long-term effects of early psychosocial deprivation on receptive language remain largely unknown.

Purpose of the Study:

• To investigate the association between early psychosocial deprivation and long-lasting receptive language outcomes.
• To examine deprivation in both institutional and family contexts.

Main Methods:

• Two prospective longitudinal studies were analyzed: the Bucharest Early Intervention Project (Romania) and the Fragile Families and Child Wellbeing Study (USA).
• Receptive language was assessed using the Peabody Picture Vocabulary Test (PPVT).
• Participants included 129 children from the Bucharest study and 3342 from the US study, with assessments spanning from infancy to late adolescence.

Main Results:

• Children with early institutional care experienced lower receptive language scores in late adolescence compared to non-institutionalized peers.
• While foster care intervention did not show lasting effects, longer institutional care duration correlated with poorer receptive language.
• Early psychosocial deprivation within US families was longitudinally associated with reduced receptive language, even when controlling for socioeconomic status.

Conclusions:

• Early psychosocial deprivation can have enduring negative consequences on receptive language abilities, extending into late adolescence.
• Psychosocial deprivation is a significant predictor of diminished receptive language skills.
