Experience sampling / Ecological Momentary Assessment (EMA)
A family of naturalistic self-report methods that signal participants during ordinary life to rate their current experience, rather than inducing a state in the lab or asking them to recall one afterward. The wiki meets it through Tong & Jia (2017), who used programmed Palm handhelds beeping ~every half hour over two days (11,141 observations from 395 people) to capture 12 positive emotions and 13 appraisals as real events unfolded.
Why it matters here: the recall contrast
EMA is best understood in the wiki against the method it displaced. Tong (2015) established the appraisal profiles of positive emotions with a recall paradigm — participants remembered a personal emotional episode and rated appraisals of the memory — and its central caveat was that recall ‘invites concerns over memory biases and schematic responses.’ Tong & Jia’s EMA study exists largely to remove that caveat: the appraisal profiles replicate when the ratings are made in the moment. That is a real methodological upgrade, and a bounded one — EMA fixes the memory problem, not the deeper correspondence problem (that appraisal–emotion co-variation is silent on causal direction, which no non-experimental method can resolve). See are-appraisals-causes-or-descriptions.
Where it sits among the wiki’s methods
EMA is the naturalistic pole of a spectrum the wiki’s emotion methods span: laboratory induction (affective-picture-viewing) controls the stimulus and measures the body but is artificial; recall and semantic norming (emotion-word-rating-norms) are cheap and broad but retrospective or conceptual; EMA is ecologically valid and memory-free but uncontrolled and non-experimental. The self-report-physiology-congruence method is a kindred within-person, repeated-measures design. Each trades a different thing away; the appraisal literature reaches for EMA when the worry is that lab and recall findings are artefacts of how the emotion was elicited or remembered.
