Note posted 9 Jun 08 : Modifications made today include a new section on predictive validity, and addition of recently published article and in in-press article, both by Nosek & Hansen, under the "CULTURE VS. PERSON" heading, which replaces a previously listed unpublished ms. of theirs. I continue to encourage all interested to send material that they are willing to be included on this page. Please also to let me know about errors, including faulty links.

Cigarette smoking and other addictive behaviors are among the main preventable risk factors for several severe and potentially fatal diseases. It has been argued that addictive behavior is controlled by an automatic-implicit cognitive system and by a reflective-explicit cognitive system, that operate in parallel to jointly drive human behavior. The present study addresses the formation of implicit attitudes towards smoking in both smokers and non-smokers, using a Go/NoGo association task, and behavioral and electroencephalographic measures. The GNAT assesses, via quantifying participants’ (...) reaction times, the strength of association between a target category and either pole of an evaluative dimension. EEG analysis is performed to determine the temporal course of the event-related potential components underlying Go/NoGo decisions and implicit attitude formation. Both smokers and non-smokers showed prolonged reaction times to smoking-related pictures when the pictures were coupled with positive evaluative words. This indicates negative implicit attitudes towards smoking in both groups alike at the time point of the behavioral response. However, only the non-smokers, not the smokers, were found to show a delay of the N200 component in the incongruent condition. This is interpreted as reflecting ambivalent or even positive implicit attitudes towards smoking in the smoker group at the time point of the N200. Our study thus provides evidence for the hypothesis that implicit attitudes are subject to changes within several hundred milliseconds after stimulus presentation, and can be altered in the course of their formation.

Addictive behaviour has qualities that make it ideal for study using implicit techniques. Addictive behaviours are mediated in part by automatic responses to drug cues, and there is sometimes social pressure to distort self-reports. However, relationships between implicit attitudes and addictive behaviours have been inconsistent. Using a new implicit measure, the affect misattribution procedure (AMP), we found consistent evidence that drinking-related behaviours are systematically related to implicit attitudes. The procedure predicted a behavioural choice to drink beer and self-reported typical drinking (...) tendencies, including hazardous drinking and alcohol-related problems. The AMP showed larger relationships with drinking behaviour than other implicit measures, and explained unique variance in drinking beyond those measures and beyond explicit measures. Though self-presentation distorted self-reports, it did not affect AMP scores. These studies highlight the importance of automatic affective responses in addictive behaviour and suggest a useful means for measuring those responses. (shrink)

How Do People Resolve Conflict Between Implicit and Explicit Attitudes? How do implicit attitudes influence behavior when they are in conflict with explicit attitudes? In Study 1, smokers' negative implicit attitudes and positive explicit attitudes towards smoking were activated. Then emotions were measured. The stronger the negative implicit attitudes that the smokers held, the stronger the conflict experienced. Study 2 showed that cognitive capacity allows for this conflict, as positive explicit and negative implicit attitudes may be applied simultaneously. The stronger (...) the negative implicit attitudes the smokers held, the stronger the conflict experienced. Smokers resolved the conflict through the inhibition of implicit attitudes. Without cognitive capacity, only implicit attitudes were applied, and thus no conflict was aroused. Study 3 confirmed that smoking cigarettes inhibited negative implicit attitudes. (shrink)
