Insights
Left-behind children show reduced brain complexity in key areas. Joint attention tasks reveal differences in brain activity, highlighting the need for early interventions to support cognitive and socioemotional development.
Area of Science:
- Neuroscience
- Developmental Psychology
- Child Development
Background:
- Early childhood experiences significantly shape brain development, particularly during the preschool years.
- Joint attention is crucial for cognitive and socioemotional development.
- Left-behind children (LBC) may face unique developmental challenges due to parental absence.
Purpose of the Study:
- To investigate neural differences in joint attention between left-behind children (LBC) and non-left-behind children (NLBC).
- To explore the relationship between brain complexity during joint attention and emotional abilities in young children.
Main Methods:
- Functional Near-Infrared Spectroscopy (fNIRS) was used to collect brain imaging data from 50 children (aged 65.08 ± 6.28 months).
- Multivariable and multiscale sample entropy (MMSE) analysis was applied to assess brain complexity.
- Participants were categorized into LBC and non-left-behind children (NLBC) groups.
Main Results:
- LBC exhibited lower brain complexity in the right prefrontal cortex compared to NLBC.
- All children demonstrated higher brain complexity when responding to joint attention compared to initiating it.
- Brain complexity during joint attention was negatively correlated with emotional abilities.
Conclusions:
- Early separation from parents, as experienced by LBC, is associated with altered neural complexity in critical brain regions.
- Joint attention processing involves distinct neural complexity patterns for initiation versus response.
- Findings underscore the importance of early intervention to foster brain development and emotional regulation in vulnerable children.
Abstract:
Human brain development is shaped by experiences, especially during preschool, the critical period for cognitive and socioemotional development. This study employed the functional Near-Infrared Spectroscopy technique to explore the neural differences between left-behind children (LBC) and non-left-behind children (NLBC) on joint attention. Through collecting brain image data of 50 children (26 boys, aged 65.08 ± 6.28 months) and conducting multivariable and multiscale sample entropy (MMSE) analysis, the present study found that: (i) LBC showed lower brain complexity than NLBC in right prefrontal cortex; (ii) all participants demonstrated higher brain complexity in responding to joint attention conditions, compared to initiating joint attention ones; (iii) their brain complexity during joint attention was negatively associated with their emotional abilities. The findings advance our understanding of early brain development in LBC by providing evidence for the neural process characteristics of joint attention. Implications for early intervention to promote their brain development are also addressed.
