The relation between cognitive rigidity and cognitive inertia was examined. Results showed that cognitive inertia was greater in individuals with mental retardation than in CA- but not MA-matched subjects without mental retardation. For individuals with mental retardation, cognitive inertia was positively correlated with CA. Results of comparisons of MA-matched individuals with and without mental retardation were not consistent with Kounin's (1941) theory. However, the current findings provided some support for Kounin's notion that there are age-related inherent structural differences that lead to greater rigidity in older adults.
