Insights
Socioeconomic status (SES) impacts children's decision-making. Middle/high-SES children showed more future-oriented choices, with distinct cardiac activity patterns observed between low and middle/high-SES groups.
Area of Science:
- Developmental Psychology
- Neuroscience
- Behavioral Economics
Background:
- Socioeconomic status (SES) is a critical determinant of cognitive development and decision-making.
- Understanding the neural and physiological underpinnings of decision-making across different SES groups is essential.
Purpose of the Study:
- To investigate the influence of socioeconomic status (SES) on children's decision-making processes.
- To examine the role of cardiac activity and awareness of task contingencies in SES-related decision-making.
- To explore potential evolutionary-developmental factors influencing these relationships.
Main Methods:
- One hundred twelve children (aged ~5.8 years) performed the Children's Gambling Task.
- Heart rate activity was continuously recorded during task performance.
- Awareness of gain/loss contingencies was assessed post-task.
Main Results:
- Distinct decision-making strategies were observed between low-SES and middle/high-SES children.
- Future-oriented decision-making was significantly associated with the middle/high-SES group.
- Contrasting cardiac patterns emerged during feedback processing and in relation to anticipatory activity and awareness.
Conclusions:
- Socioeconomic status significantly shapes children's decision-making strategies and associated physiological responses.
- Future-oriented decision-making may be differentially influenced by SES, potentially linked to distinct cardiac activity patterns.
- Findings suggest an evolutionary-developmental framework for understanding SES disparities in decision-making.
Abstract:
This study examined how socioeconomic status (SES) influences on decision-making processing. The roles of anticipatory/outcome-related cardiac activity and awareness of task contingencies were also assessed. One hundred twelve children (Mage = 5.83, SDage = 0.32; 52.7% female, 51.8% low-SES; data collected October-December 2018 and April-December 2019) performed the Children's Gambling Task, while heart rate activity was recorded. Awareness of gain/loss contingencies was assessed after completing the task. Distinct decision-making strategies emerged among low and middle/high-SES children. Despite similar awareness levels between SES groups, future-oriented decision-making was linked solely to the middle/high-SES group. Somatic markers did not manifest unequivocally. However, contrasting cardiac patterns were evident concerning feedback processing and the association between anticipatory activity and awareness (low: acceleration vs. middle/high: deceleration). Results are interpreted from an evolutionary-developmental perspective.
