AnnotationThe age-related differences in split and problem-difficulty effects were tested in 138 French adults aged 20-80, who performed a simple and a complex inequality verification task (e.g. 6 + 3 < 11; and 271 + 182 < 458, true or false?). Split effects in verification tasks (i.e. better performance for large-split than for small-split problems) reflect strategy selection between non-exhaustive verification (e.g. evaluation of plausibility; estimation) and exhaustive verification (e.g. retrieval; calculation). Problem-difficulty effects (i.e. better performance for easy that hard problems) reflect calculation processing. Results showed decreased split effects across age groups, particularly in this complex task. Moreover, problem-difficulty effects did not vary across age groups. Age-related changes were mostly mediated by age-related declines to processing speeds. (RH).
