Insights
Socioeconomic status (SES) impacts school-aged children's brain function and cognition. Different brainwave frequencies, like alpha, gamma, and theta, link to specific SES factors and cognitive skills, revealing unique developmental pathways.
Area of Science:
- Neuroscience
- Developmental Psychology
- Cognitive Science
Background:
- Childhood socioeconomic status (SES) is linked to brain function and cognitive development.
- Previous research focused on infants, leaving a gap in understanding school-aged children's neural development related to SES.
- Resting-state electroencephalography (rsEEG) shows promise in linking environmental factors to brain activity.
Purpose of the Study:
- To investigate how specific aspects of SES (income, maternal education) influence resting-state brain function in school-aged children.
- To identify which neural frequencies are differentially associated with SES and cognitive outcomes (vocabulary, working memory).
- To elucidate unique neural pathways through which SES impacts cognitive and neural development.
Main Methods:
- Multivariate pattern analysis (MVPA) applied to resting-state electroencephalography (rsEEG) data.
- Examined school-aged children (8-15 years) across various SES levels.
- Correlated specific rsEEG frequency bands (alpha, gamma, theta) with SES indicators and cognitive assessments.
Main Results:
- Alpha frequency was associated with both income and maternal education.
- Lower gamma frequency fluctuations predicted maternal education and vocabulary outcomes.
- Theta frequency fluctuations related to income and working memory ability.
Conclusions:
- SES influences cognitive and neural development through distinct pathways in school-aged children.
- Specific brainwave frequencies serve as neural markers for SES-related cognitive development.
- Findings highlight the importance of SES in shaping brain function and cognitive abilities during childhood.
Abstract:
Children's socioeconomic status (SES) is related to patterns of intrinsic resting-state brain function that subserve relevant cognitive processes over the course of development. Although infant research has demonstrated the association between children's environments, cognitive outcomes, and resting-state electroencephalography (rsEEG), it remains unknown how these aspects of their environment, tied to SES, impact neural and cognitive development throughout the school years. To address this gap, we applied a multivariate pattern analysis (MVPA) to rsEEG data to identify which neural frequencies at rest are differentially associated with unique aspects of socioeconomic status (SES; income and maternal education) and cognitive (vocabulary, working memory) outcomes among school-aged children (8-15 years). We find that the alpha frequency is associated with both income and maternal education, while lower gamma and theta fluctuations are tied to dissociable aspects of SES and cognitive outcomes. Specifically, changes in the gamma frequency are predictive of both maternal education and vocabulary outcome, while changes in the theta frequency are related to both income and working memory ability. The current findings extend our understanding of unique pathways by which SES influences cognitive and neural development in school-aged children.
