Abstract
In each trial human smokers n=16 were presented with stimuli for which attention was measured with an eyetracker Participants then reported their cigarette reward expectancy before performing or not an instrumental tobaccoseeking response that was rewarded with cigarette gains if the S+ had been presented or punished with cigarette losses if the S− had been presented Following training participants rated the pleasantness of stimuliThe S+ only brought about conditioned behaviour in an aware group those who expected the cigarette reward outcome when presented with the S+ This aware group allocated attention to the S+ performed the instrumental tobaccoseeking response selectively in the presence of the S+ and rated the S+ as pleasant No conditioned behaviour was seen in the unaware group those who did not expect the cigarette reward outcome in the presence of the S+
