Choice effects on temporal binding of action and outcomes: Examining the role of outcome focus and measures of time interval estimation

The ability to make one's own choices is vital to the experience of intentional behavior. Such agency experiences are reflected in the perceptual compression of time between actions and resulting outcomes. Whereas some studies show that choice limitations weaken temporal binding, other studies do not find such an effect. Reviewing the literature, we noted two different factors, that may moderate choice limitation effects on temporal binding: (a) the level of action representation, according to which individuals focus on their motor actions or the consequences they produce; and (b) the response mode of the time interval estimation measurement where participants report numbers or use a slider to indicate time intervals. Testing these conceptual and methodological factors in two separate experiments yielded clear effects of choice limitation on temporal binding but no clear moderator role of the two factors. Interestingly, overall analyses showed that the choice limitation effect gradually vanishes over time. We briefly discuss the findings in the context of everyday autonomy restrictions in shaping conscious experiences of intentional action.
