摘要	The Day Reconstruction Method (DRM), introduced by Kahneman, Krueger, Schkade, Schwarz, and Stone in 2004, is a technique for measuring how people experience the activities of their daily lives without the burden of real-time sampling. Respondents systematically reconstruct the previous day, dividing it into a sequence of episodes -- like scenes in a film -- and report for each episode what they were doing, where, with whom, and how they felt. By anchoring recall in concrete, ordered episodes, the method reduces the memory biases that plague global retrospective reports while approximating the affective information obtained from experience sampling. The DRM yields duration-weighted measures of experienced well-being, such as net affect and the U-index (the proportion of time spent in an unpleasant state), and reveals how feelings vary across activities and contexts. It became a key tool for studying experienced (as opposed to evaluated) well-being and the affective texture of everyday life.	The ego depletion paradigm, introduced by Baumeister, Bratslavsky, Muraven, and Tice in 1998, tests the strength model of self-control, which holds that acts of self-regulation draw on a limited, shared resource that becomes temporarily depleted with use. In the classic dual-task design, participants first perform a task requiring self-control -- such as resisting tempting food, suppressing emotion, or overriding a habitual response -- or an equivalent task without such demands, and then perform a second, unrelated self-control task. The prediction is that those who exerted self-control on the first task perform worse on the second, exhibiting ego depletion. The 1998 demonstrations were highly influential and generated a vast literature, but large-scale replication efforts in the 2010s yielded weak or inconsistent results, making ego depletion a central case in debates about replicability and prompting theoretical revisions and stricter methodological standards.
