Theories of self-awareness and social in- and exclusion were useful in understanding consequences of a HV smoking ban on continuing smokers. Four different types of responses were identified, i.e. (1) actively trying to quit, (2) socially conscious smoking, (3) feeling victimised and (4) rejecting the norm. Implications for future smoke-free legislation are discussed.

This study examined whether smokers' perceived level of stigmatization changed after the implementation of smoke-free hospitality industry legislation and whether smokers who smoked outside bars reported more perceived stigmatization. Longitudinal data from the International Tobacco Control (ITC) Netherlands Survey was used, involving a nationally representative sample of 1447 smokers aged 15 years and older. Whether smoke-free legislation increases smokers' perceived stigmatization depends on how smokers feel about smoking outside. The level of perceived stigmatization did not change after the implementation of smoke-free hospitality industry legislation in the Netherlands, possibly because most Dutch smokers do not feel negatively judged when smoking outside.

Generally, the suppression of unwanted thoughts is found to be ineffective. Moreover, in the longer run, suppression attempts may backfire in that they produce a delayed increase in unwanted thoughts (i.e. a rebound effect). This ineffectiveness and paradox have been observed in various studies, and with various targets, such as neutral thoughts, obsessive intrusions, worries, addictive urges, and phobia-related cognitions. The present study sought to explore the effect of suppression of a different intrusion, namely a hallucination. Healthy undergraduates were exposed to a laboratory procedure that was to provoke hallucinations. Half of the participants were additionally given instructions to suppress the hallucinations. Results indicated that suppression was somewhat effective in the short run, but ineffective in the long run. However, no rebound effect was observed.

In four experiments, the characteristics of participants' mental imagery of World War II were investigated. In the first experiment, mental images of WWII were found to lack clarity compared to mental images of a Medieval war. In a second experiment, the association between the lack of clarity of WWII mental images, and the underestimation of Nazi cruelties was explored. In line with the expectation based on source monitoring theory, participants whose mental imagery was less clear more readily endorsed an item modelling denial of Nazi cruelties. In a third experiment, these findings were replicated. In experiment 4, participants' WWII mental images were manipulated by means of film footage. Ultimately, it is argued that viewing film footage of poor quality results in unclear mental images of WWII, and that lack of clarity of WWII imagery is associated with a tendency to Nazi cruelties.
