Description
Tese de doutoramento, Psicologia (Psicologia Social), Universidade de Lisboa, Faculdade de Psicologia e de Ciências da Educação, 2010 Research on environmental behavior continues not to answer the question: why don't people behave the way we want them to? Or differently, what are the barriers and constraints to proenvironmental behaviors? For this a model is proposed and from this, habit is studied as a barrier, being defined as goal-directed automatic behavior that is mentally represented and can be triggered by environmental cues (e.g. Aarts & Dijksterhuis, 2000). Accordingly, it shares some characteristics with other types of mental representations such as stereotypes and attitudes for example, namely its dynamism which results from the interaction between the situation and cognitive processes. Based on the Theory of Systems Goals (Kruglanski et al., 2002) and the mental constructs activation rules (Higgins & Brendl, 1995), habits can also be considered to result from the interaction between 2 sources of activation: context applicability (in our studies defined as perceived applicability of habit to the means to attain the goal present in the decision context) and cognitive accessibility (through goal priming or chronicity). We manipulated these in a number of online shopping simulations organic vs. non-biological products buying or habitual vs. non-habitual products buying. Results demonstrate a perceived applicability effect with more habitual (studies 2 and 3) or non-biological (study 1) products chosen in a familiar than in a new context and greater consistency in non-organic choice within 3 choices in the same list (study 1). Strong habit participants (high chronic accessibility) consistently choose the habitual product even when context changes (study 2). The goal priming does not show the expected effect (study 2 and 3) and may indicate the presence of goal activation suppression effects (Study 2). Finally, results indicate that habit can resist the effect of implementation intentions (study 4) or be "broken" for certain context changes (studies 5a + 5 b)
