Implementation intentions are if-then plans that spell out in advance how one wants to strive for a set goal. For the if-component, a critical cue is selected (e.g., a good opportunity, an anticipated obstacle) that is linked to a goal-directed response in the then-component. Implementation intentions are known to enhance the rate of goal attainment. They do so by delegating action control to situational cues thus endowing action control with features of automaticity.
