Abstract

This study examined the effects of smoking and smoking deprivation on the articulatory loop of working memory. Forty subjects (20 smokers and 20 non-smokers) performed tasks involving serial recall of letters on two occasions 1 week apart. In each test one part was conducted with articulatory suppression and the other without it. The smokers completed one test following 12 h of smoking deprivation, and the other after smoking a cigarette. The order of suppression/non-suppression conditions and the order of smoking and smoking deprivation were balanced across subjects. The results showed that deprived smokers performed significantly worse than both smoking smokers and non-smokers in the task without suppression. Although all the subjects performed significantly worse whilst under articulatory suppression, smoking status was not found to influence performance here. These results imply that smoking has the effect of returning the smoker to a comparable level of performance to that seen in non-smokers, and suggest that smoking abstinence has a negative effect when performance involves the articulatory loop.
