We discuss some research that has examined approach motivational urges and how this research clarifies the definition of approach motivation. Our research and that of others have raised doubts about the commonly accepted definition of approach motivation, which views it as a positive affective state triggered by positive stimuli. We review evidence that suggests: (a) that approach motivation is occasionally evoked by negative stimuli; (b) that approach motivation may be experienced as a negative state; and (c) that stimuli are unnecessary (...) to evoke approach motivation.

Two core motivational systems have been conceptualized as underlying emotion and behavior. The approach system drives the organism toward stimuli or events in the environment, and the avoidance system instead deters the organism away from these stimuli or events. This approach—avoidance dichotomy has been central to theories of emotion. Advances in neuroscience complementing well-designed behavioral experiments have begun to elucidate the neural mechanisms underlying approach—avoidance motivation, suggesting that these two systems exist in parallel and are lateralized in the brain. This (...) review explores the notion of approach—avoidance and the cerebral lateralization of these motivational tendencies. (shrink)

Although anger as a negative emotion is associated with unpleasantness, recent research on anger highlights its motivational effect. The present study tested whether individuals experience both, an unpleasant and an activating affect, after real-life provocations. Results revealed that an anger situation evoked not only typical subjective and cardiovascular anger reactions but also a sense of strength, which is a positive affect. A comparison of participants with low versus high anger disposition according to the STAXI-2 at baseline, treatment, and recovery showed (...) that participants with high trait anger consistently scored higher in subjective ratings of feeling strong than their counterparts did. Moreover, we found a larger and longer lasting effect of feeling strong than feeling angry after an anger treatment. Thus, differences in anger disposition influence the positive correlation between trait anger and positive affect. (shrink)
