Parental acceptance-rejection and brain network connectivity: A naturalistic neuroimaging study

Area of Science:

• Neuroscience
• Developmental Psychology
• Clinical Psychology

Background:

• Interpersonal acceptance-rejection theory (IPARTheory) posits early relationships shape development.
• Childhood experiences of parental acceptance or rejection can have lasting psychological impacts.
• Brain connectivity patterns are crucial for emotional and cognitive regulation.

Purpose of the Study:

• To investigate the association between childhood memories of parental acceptance/rejection and intrinsic brain connectivity in young adults.
• To explore how these early experiences relate to functional connectivity in networks involved in emotion regulation, cognitive control, and self-referential processing.
• To compare brain network connectivity between psychologically well-adjusted, accepted individuals and maladjusted, rejected individuals.

Main Methods:

• Forty young adults (aged 19) completed self-report measures of childhood parental experiences and psychological adjustment.
• Functional magnetic resonance imaging (fMRI) was used to assess intrinsic brain connectivity while participants viewed naturalistic stimuli.
• Analyses focused on the salience, default mode, and frontoparietal networks, and specific brain regions like the amygdala, anterior cingulate cortex, and insula.

Main Results:

• The AcceptedAdjusted group exhibited stronger functional connectivity within key brain networks, indicating coordinated processing.
• The RejectedMaladjusted group showed weaker connectivity across systems and heightened default mode network connectivity, linked to rumination.
• Parental rejection was associated with altered connectivity in the amygdala, anterior cingulate cortex, and insula.

Conclusions:

• Early parental experiences significantly shape the organization of large-scale brain networks.
• Memories of parental acceptance are linked to more integrated brain function related to emotional and cognitive regulation.
• Parental rejection in childhood is associated with brain connectivity patterns that may underlie psychological maladjustment and emotional difficulties.
