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.

The present article puts forward a behavioral disinhibition hypothesis stating that, often, at least some levels of behavioral disinhibition are needed to overcome people’s inhibition to intervene in dilemmatic situations in which they have to choose between different actions with good reasons for each of the actions involved. Results reported indeed show that people to whom disinhibited behaviors were salient or people with stronger predispositions toward behavioral disinhibition were more likely to intervene in trolley and footbridge dilemmas.
