Though panel data are increasingly used in the social sciences, the question whether repeatedly participating in a panel survey affects respondents' attitudes and (response) behaviour is still largely unsolved. Drawing on a model of associative networks that is extended by assumptions on survey satisficing, we present a theoretical framework that emphasizes the role of strength-related attributes of attitudes (accessibility, internal consistency, extremity) and motivation in respondents' information processing. In particular, we argue that -- depending on respondents' predispositions -- occupation with survey questions enhances attitude strength, which results in increasing attitude stability and influence on thoughts and behaviours. Against this background, we bring together hitherto unconnected results from previous research and thus contribute to a more thorough understanding of both the mechanisms and the multifaceted outcomes of panel conditioning.
