The aim of this investigation was to determine how cognitive performance was associated with positive and negative affect and life satisfaction over time. This study involved a secondary longitudinal analysis of cross-section data collected at Phase I (1988–1992) and during an 18-month longitudinal followup at Phase II (1992–1998) of the Georgia Centenarian Study. Participants included  N  = 137 centenarians at Time 1 and  N  = 68 survivors at Time 2. Significant stability in cognitive impairment existed at Time 1 and Time 2 for positive ( β  = .55,  P  < .01) and negative affect ( β  = .54,  P  < .01) models. Negative affect at Time 1 was associated with lower life satisfaction at Time 1 ( β  = −.42,  P  < .01 ). In addition, cognitive impairment at Time 2 was associated with decreased positive emotionality at Time 2 ( β  = −.39,  P  > .01). Furthermore, greater positive affect at Time 2 was associated with greater satisfaction with life at Time 2 ( β  = .35,  P  < .01). It appears that positive emotionality contemporaneously influences the association between cognitive impairment and life satisfaction among centenarians. Implications relative to improving life satisfaction among centenarians are discussed.
