Сводка	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.	Facial electromyography (EMG) measures affect by recording the tiny electrical signals produced by facial muscles, providing an objective, continuous index of emotional valence and intensity that can detect reactions too subtle or fleeting to produce a visible expression. Cacioppo, Petty, Losch, and Kim showed in 1986 that activity over two muscle regions differentiates affect: the corrugator supercilii (the brow muscle that furrows in frowning) increases with negative affect, while the zygomaticus major (the cheek muscle that pulls in smiling) increases with positive affect, and amplitudes scale with the intensity of the reaction. Because surface electrodes capture muscle activity even when no overt expression occurs, facial EMG offers a sensitive, hard-to-fake measure of evaluative responses widely used in research on attitudes, emotion, persuasion, and social perception, often paired with reaction-time and self-report measures.
