Affective and cognitive control of persons and behaviours

Three studies assessed the relative contribution of affect and cognition to determining behavioural intentions for a variety of behaviours using both betweenparticipants and within‐participants analyses. The between‐participants analyses showed that affect tends to make more of a contribution than does cognition for more behaviours. However, the within‐participants analyses indicated that there are strong individual differences among people. Some people are more under affective control, across behaviours, whereas other people are more under cognitive control. The most interesting finding was that, despite the potential independence of between‐participants and within‐participants analyses (Mischela, 1990), between‐participants analyses on subsamples created from the within‐participants analyses showed significant dependence. The predictive validity of affect vs. cognition depended upon whether participants were affectively or cognitively controlled.
