Temporal discounting and self-continuity: Age-dependent patterns and implications.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Behavioral Economics

Background:

• Intertemporal decision-making involves choosing between immediate and delayed rewards, a process influenced by temporal discounting.
• Self-continuity, the sense of being the same person over time, has been linked to temporal discounting, but age-related effects are not well understood.

Purpose of the Study:

• To investigate the relationship between age, self-continuity (explicit and implicit), and temporal discounting.
• To determine if age moderates the association between self-continuity and intertemporal choices.

Main Methods:

• Sixty-seven younger and fifty-two older adults completed assessments for temporal discounting, explicit self-continuity, and implicit self-continuity.
• Statistical analyses were performed to compare groups and examine correlations.

Main Results:

• Older adults exhibited significantly higher temporal discounting rates and greater explicit self-continuity than younger adults.
• A negative correlation between explicit future self-continuity and temporal discounting was found in younger adults but not in older adults.
• No age-related differences were observed in implicit self-continuity measures or their association with temporal discounting.

Conclusions:

• Age significantly influences temporal discounting and explicit self-continuity, with distinct age-specific patterns in their relationship.
• The findings suggest that interventions targeting self-continuity for decision-making may need to be age-tailored.
• Further research is needed to fully elucidate the lifespan dynamics of self-continuity and intertemporal choices.
