Table 1. Experimental design. Each session began with a parity task, followed by a comparison task (Session1), or two mental rotation tasks (Session2).
Order 1 | Session 1 | Parity-Order 1 | Comparison-Order 1 | |
Session 2 | Parity-Order 1 | MR1 | MR2 | |
Order 2 | Session 1 | Parity-Order 1 | Comparison-Order 2 | |
Session 2 | Parity-Order 1 | MR2 | MR1 | |
Order 3 | Session 1 | Parity-Order 2 | Comparison-Order 1 | |
Session 2 | Parity-Order 2 | MR1 | MR2 | |
Order 4 | Session 1 | Parity-Order 2 | Comparison-Order 2 | |
Session 2 | Parity-Order 2 | MR2 | MR1 |
