Document Summary

The act of smoking has reinforcing properties in the absence of the biologically. Smoking is not zero in the no-nicotine cigarettes. Any stimulus that predicts the reinforcer will get motivational value. One effect of introducing a reinforcer into a learning situation is to confer motivating power (motivational salience) on previously non-motivating stimuli. The stimulus acquires secondary reinforcing properties and thus it becomes a conditioned motivator. Groups: no cigarettes, no nicotine cigarettes, regular cigarettes reinforcing stimulus. ) attribution of motivational salient incentive/aversive stimuli (subjective) emotion (like/dislike of the stimulus) and motivation (wanting/not wanting the stimulus) are separate processes. Facial expressions, but they can be manipulated (you are manipulating how you are perceived by others) So we look at babies, who cannot control their facial expressions. Brain dopamine systems mediate the pleasure produced by food and other unconditioned incentives. Dopamine and wanting: 6-hydroxydopamine lesions to the vta produced severe aphagia. It"s not reward that"s being encoded here .
