Experiment 2 had three primary aims. First, we tested the impact of giving time on feelings of time affluence against an even stricter standard: actually receiving an unexpected windfall of free time. In a laboratory session, some participants were assigned to give time to help another person, and a control group was allowed to leave the session early. Although receiving a windfall of free time objectively increases the time available to do other things, we predicted that giving time would lead to even greater perceptions of time affluence than getting time would. Second, we introduced a new measure of time affluence: measuring the amount of time that individuals felt they currently had (rather than the amount of time they felt they had in the future). Our account posits that giving time makes people feel efficacious—like they can get more done. Therefore, we also included behavioral measures reflective of feeling less time constrained and more capable: committing to future engagements and following through on those time commitments.
