Using the Implicit Association Test to investigate attitude-behaviour consistency for stigmatised behaviour

To consciously bolster behaviour that is disapproved by others (i.e., stigmatised behaviour) people may hold and report a favourable attitude toward the behaviour. However, achieving such bolstering outside awareness may be more difficult. Explicit attitudes were measured with self-report measures, and the Implicit Association Test was used to assess implicit attitudes toward behaviour held by stigmatised actors (smokers) and nonstigmatised actors (vegetarians and omnivores). Smokers' showed greater attitude-behaviour consistency in their explicit attitudes toward smoking that in their implicit attitudes. By contrast, vegetarians and omnivores showed attitude-behaviour-consistency at both implicit and explicit lcvels. Smokers' implicit negative attitudes toward smoking may reflect its status as a stigmatised behaviour, or its addictive nature.
