Machine learning methods provide powerful tools to map physical measurements to scientific categories. But are such methods suitable for discovering the ground truth about psychological categories? We use the science of emotion as a test case to explore this question. In studies of emotion, researchers use supervised classifiers, guided by emotion labels, to attempt to discover biomarkers in the brain or body for the corresponding emotion categories. This practice relies on the assumption that the labels refer to objective categories that can be discovered. Here, we critically examine this approach across three distinct datasets collected during emotional episodes- measuring the human brain, body, and subjective experience- and compare supervised classification studies with those from unsupervised clustering in which no a priori labels are assigned to the data. We conclude with a set of recommendations to guide researchers towards meaningful, data-driven discoveries in the science of emotion and beyond.

Over Time

Emotions are processes that unfold over time. As a consequence, a better understanding of emotions can be reached only when their time–related characteristics can be assessed and interpreted adequately. A central aspect in this regard is the duration of emotional experience. Previous studies have shown that an emotional experience can last anywhere from a couple of seconds up to several hours or longer. In this article, we examine to what extent specific appraisals of the eliciting event may account for variability in emotion duration and to what degree appraisal–duration relations are universal or culture specific. Participants in 37 countries were asked to recollect emotional episodes of fear, anger, sadness, disgust, shame and guilt. Subsequently, they were asked to report the duration of these episodes and to answer a number of questions regarding their appraisal of the emotion–eliciting event. Multi–level analyses revealed that negative emotions last especially long when the eliciting event and its consequences are perceived to be incongruent with the individual's goals, values and self–ideal, creating a mismatch. These relations are largely universal, although evidence for some limited variability across countries is found as well. Copyright © 2013 European Association of Personality Psychology

The issues addressed in this commentary include: (1) the appropriate conceptualization of “appraisal”; (2) the nature and unfolding of emotional episodes over time; (3) the interrelationships between the dynamic elements of the appraisal process and their effects on other emotion components, as well as repercussions on ongoing appraisal in a recursive process; and (4) the use of brain research to constrain and inform models of emotion.
