Older adults maintain arithmetic fact networks, showing preserved problem size effects. However, they exhibit reduced sensitivity to proactive interference in multiplication tasks compared to younger adults.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Human Aging Research
Background:
- Arithmetic facts (AFs) are crucial for rapid calculation retrieval from memory.
- Problem size and proactive interference effects are key modulators of AF performance.
Purpose of the Study:
- To examine age-related changes in the problem size effect and proactive interference in AF solving.
- To compare young and older adults' performance on multiplication tasks.
Main Methods:
- Multiplication production task comparing young and older adults.
- Independent measure to assess proactive interference in multiplication solving.
Main Results:
- Both age groups showed performance decrements with increased problem size and interference.
- The problem size effect remained consistent across age groups, suggesting preserved AF networks.
- Older adults demonstrated reduced sensitivity to proactive interference compared to younger adults.
Conclusions:
- Arithmetic fact networks appear preserved in older adults.
- Ageing may mitigate the impact of proactive interference in multiplication problem-solving.
