CONTEXT & GOALS • Strategy combination: Better performance for problems violating both five- and parity-rules (Hinault et al., in revision). • Aging effect on strategy selection and execution (Lemaire, 2010). • Sequential modulations of poorer-strategy effects (Lemaire & Hinault, 2013). Here, we investigated Aging effect on strategy combination, and its sequential modulations.
METHOD • Multiplication problem (25 young adults and 25 older adults) 4 x 68 = 273 True ? False ? • 2 rule-checking strategies: - Parity-rule: 4 x 37 = 148 - Five-rule: 5 x 32 = 160 • 4 trial types: No-Rule Violation
Parity-Rule Violation
Five-Rule Violation
Two-Rule Violation
5 x 26 = 140
5 x 12 = 65
5 x 32 = 164
32 x 69 (UD)
RESULTS No Rule
