    Some Recommendations on the Use of Daily Life Methods in Affective Science
    Kuppens, P ; Dejonckheere, E ; Kalokerinos, EK ; Koval, P (SPRINGERNATURE, 2022-06)
    Real-world emotions are often more vivid, personally meaningful, and consequential than those evoked in the lab. Therefore, studying emotions in daily life is essential to test theories, discover new phenomena, and understand healthy emotional functioning; in short, to move affective science forward. The past decades have seen a surge of research using daily diary, experience sampling, or ecological momentary assessment methods to study emotional phenomena in daily life. In this paper, we will share some of the insights we have gained from our collective experience applying such daily life methods to study everyday affective processes. We highlight what we see as important considerations and caveats involved in using these methods and formulate recommendations to improve their use in future research. These insights focus on the importance of (i) theory and hypothesis-testing; (ii) measurement; (iii) timescale; and (iv) context, when studying emotions in their natural habitat.

    Social Support Predicts Differential Use, but not Differential Effectiveness, of Expressive Suppression and Social Sharing in Daily Life
    Pauw, LS ; Medland, H ; Paling, SJ ; Moeck, EK ; Greenaway, KH ; Kalokerinos, EK ; Hinton, JDX ; Hollenstein, T ; Koval, P (SPRINGERNATURE, 2022-09)
    UNLABELLED: While emotion regulation often happens in the presence of others, little is known about how social context shapes regulatory efforts and outcomes. One key element of the social context is social support. In two experience sampling studies (Ns = 179 and 123), we examined how the use and affective consequences of two fundamentally social emotion-regulation strategies-social sharing and expressive suppression-vary as a function of perceived social support. Across both studies, we found evidence that social support was associated with variation in people's use of these strategies, such that when people perceived their environments as being higher (vs. lower) in social support, they engaged in more sharing and less suppression. However, we found only limited and inconsistent support for context-dependent affective outcomes of suppression and sharing: suppression was associated with better affective consequences in the context of higher perceived social support in Study 1, but this effect did not replicate in Study 2. Taken together, these findings suggest that the use of social emotion-regulation strategies may depend on contextual variability in social support, whereas their effectiveness does not. Future research is needed to better understand the circumstances in which context-dependent use of emotion regulation may have emotional benefits, accounting for personal, situational, and cultural factors.

    Momentary Emotion Differentiation: The Derivation and Validation of an index to Study Within-Person Fluctuations in Emotion Differentiation.
    Erbas, Y ; Kalokerinos, EK ; Kuppens, P ; van Halem, S ; Ceulemans, E (SAGE Publications, 2022-06)
    Emotion differentiation refers to the tendency to label emotions in a granular way. While differentiation is an important individual difference in the context of psychological well-being, it is unknown how it fluctuates within individuals. Such a within-person measure is important, since it would allow the study of how changes in differentiation predict subsequent levels of other variables of interest. Here, we present a framework to study emotion differentiation at the within-person level by introducing a momentary emotion differentiation index. This index is directly derived from the classical emotion differentiation index, the intraclass correlation. We first give a theoretical derivation of this index. Next, using data from two experience sampling studies, we show how this new momentary index is related to other momentary indicators of well-being, and take the first steps in building its nomological network. A better understanding of within-person fluctuations in emotion differentiation will allow us to identify the causes and consequences of these fluctuations, and search for ways to teach individuals to increase their level of emotion differentiation.

    The Relation Between Positive and Negative Affect Becomes More Negative in Response to Personally Relevant Events
    Dejonckheere, E ; Mestdagh, M ; Verdonck, S ; Lafit, G ; Ceulemans, E ; Bastian, B ; Kalokerinos, EK (AMER PSYCHOLOGICAL ASSOC, 2021-03)
    Can we experience positive (PA) and negative affect (NA) separately (i.e., affective independence), or do these emotional states represent the mutually exclusive ends of a single bipolar continuum (i.e., affective bipolarity)? Building on previous emotion theories, we propose that the relation between PA and NA is not invariable, but rather fluctuates in response to changing situational demands. Specifically, we argue that our affective system shifts from relative independence to stronger bipolarity when we encounter events or situations that activate personally relevant concerns. We test this idea in an experience sampling study, in which we tracked the positive and negative emotional trajectories of 101 first-year university students who received their exam results, an event that potentially triggers a personally significant concern. Using multilevel piecewise regression, we show that running PA-NA correlations become increasingly more negative in the anticipation of results release, indicating stronger affective bipolarity, and ease back toward greater independence as time after this event passes. Furthermore, we show that this dynamic trajectory is particularly apparent for event-related PA and NA, and not affect in general, and that such shifts are partly a function of the importance people attribute to that event. We suggest that such flexible changes in the affect relation may function as an emotional compass by signaling personally relevant information, and create a motivational push to respond to these meaningful events in an appropriate manner.

    The social functions of positive emotions
    Sels, L ; Tran, A ; Greenaway, KH ; Verhofstadt, L ; Kalokerinos, EK (Elsevier, 2021-06-01)
    Emotions unfold in the context of social interactions and relationships, where they serve social ends. In this review, we discuss recent research on the social functions served by positive emotions. We identify three functions of positive emotions: intimacy, impression, and influence functions. Intimacy functions refer to the benefits individuals acquire in improving their bond with others. Impression and influence functions follow from the information that others derive from positive emotion expressions. Positive emotions can therefore be used in social contexts to achieve goals such as maintaining social standing or enhancing motivation in others to achieve important goals.

    Neuroticism may not reflect emotional variability
    Kalokerinos, EK ; Murphy, SC ; Koval, P ; Bailen, NH ; Crombez, G ; Hollenstein, T ; Gleeson, J ; Thompson, RJ ; Van Ryckeghem, DML ; Kuppens, P ; Bastian, B (NATL ACAD SCIENCES, 2020-04-28)
    Neuroticism is one of the major traits describing human personality, and a predictor of mental and physical disorders with profound public health significance. Individual differences in emotional variability are thought to reflect the core of neuroticism. However, the empirical relation between emotional variability and neuroticism may be partially the result of a measurement artifact reflecting neuroticism's relation with higher mean levels-rather than greater variability-of negative emotion. When emotional intensity is measured using bounded scales, there is a dependency between variability and mean levels: at low (or high) intensity, it is impossible to demonstrate high variability. As neuroticism is positively associated with mean levels of negative emotion, this may account for the relation between neuroticism and emotional variability. In a metaanalysis of 11 studies (N = 1,205 participants; 83,411 observations), we tested whether the association between neuroticism and negative emotional variability was clouded by a dependency between variability and the mean. We found a medium-sized positive association between neuroticism and negative emotional variability, but, when using a relative variability index to correct for mean negative emotion, this association disappeared. This indicated that neuroticism was associated with experiencing more intense, but not more variable, negative emotions. Our findings call into question theory, measurement scales, and data suggesting that emotional variability is central to neuroticism. In doing so, they provide a revisionary perspective for understanding how this individual difference may predispose to mental and physical disorders.
