Social Psychophysiology and Health Lab


About the lab

Social Psychophysiology & Health Lab is equipped for measurements of physiological and behavioral signals important for understanding of social, emotional, and motivational determinants of somatic health and healthy relationships. In addition to the experimental laboratory research, our team conducts field research and internet studies in order to further examine the phenomena in laboratory conditions.

Campbell et al. (2021) claimed motivational intensity (approach–avoidance) is a redundant construct that is merely another label for valence (positive–negative). They based their conclusion on a high correlation between valence and motivational intensity when participants rated pictures. We present arguments that their conclusion was based on inadequate evidence. First, we explain how high correlation fails to identify meaningful and consistent affective states where motivational intensity is essential. As a counterargument, we present replicated and cumulative empirical evidence of differences between affective states with equal valence and arousal but different motivational intensities such as desire or enthusiasm versus amusement. Second, we emphasize that correlations do not account for relative differences between valence and motivational intensity levels (which we termed undermotivated and overmotivated affect). We illustrate this by presenting how valence and motivational intensity diverge during watching affective video clips. We conclude the opposite of Campbell’s team, that is, motivational intensity is a viable concept deserving further attention. However, studying motivational intensity requires specific strategies to dissect what is possible within affect from the most frequent. We formulate several recommendations regarding the choice of stimuli (overrepresentation of specific categories) and measurement (e.g., measuring dimensions of affect along with a broad range of discrete emotions and motivational concepts). This might improve the study in affective science toward stronger differentiation within the core of human affect.
The undoing hypothesis proposes that positive emotions serve to undo sympathetic arousal related to negative emotions and stress. However, a recent qualitative review challenged the undoing effect by presenting conflicting results. To address this issue quantitatively, we conducted a meta-analytic review of 16 studies ( N = 1,220; 72 effect sizes) measuring sympathetic recovery during elicited positive emotions and neutral conditions. Findings indicated that in most cases, positive emotions did not speed sympathetic recovery compared to neutral conditions. However, when a composite index of cardiovascular reactivity was used, undoing effects were evident. Our findings suggest the need for further work on the functions of positive emotions.
Capitalization is an interpersonal process in which individuals (capitalizers) communicate their accomplishments to others (responders). When these attempts to capitalize are met with enthusiastic responses, individuals reap greater personal and social benefits from the accomplishment. This research integrated the interpersonal model of capitalization with moral foundations theory to examine whether accomplishments achieved through immoral (vs. moral) means disrupt the interpersonal processes of capitalization. We hypothesized that an accomplishment achieved through immoral (vs. moral) means would suppress the positive affective response often reaped from capitalizing on good news. We conducted two, mixed-methods experiments in which individuals interacted with a stranger (Study 1) or with their romantic partner (Study 2). We found that responders exhibited greater self-reported negative emotions, avoidance motivation, and arousal when reacting to capitalizers' immoral (vs. moral) accomplishments. In turn, greater negative affect predicted less enthusiastic verbal responses to capitalization attempts. In Study 2 we found that immoral accomplishments increased avoidance motivation, which contrary to our expectations, increased expressions of happiness. These studies reveal that the moral means by which accomplishments are achieved can disrupt the interpersonal process of capitalization. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
Autonomic nervous system (ANS) activity is a fundamental component of emotional responding. It is not clear, however, whether positive emotional states are associated with differential ANS reactivity. To address this issue, we conducted a meta-analytic review of 120 articles (686 effect sizes, total N = 6,546), measuring ANS activity during 11 elicited positive emotions, namely amusement, attachment love, awe, contentment, craving, excitement, gratitude, joy, nurturant love, pride, and sexual desire. We identified a widely dispersed collection of studies. Univariate results indicated that positive emotions produce no or weak and highly variable increases in ANS reactivity. However, the limitations of work to date – which we discuss – mean that our conclusions should be treated as empirically grounded hypotheses that future research should validate.
Studies indicated that individuals who tend to smile while taking their photographs tend to experience more positive emotions in their life and, in turn, achieve superior outcomes in several life domains. However, little is known whether positive emotionality revealed in players' profile photographs is related to sports performance. This study examined whether the smiling intensity in volleyball players' profiles (full, partial, and no smile) predicted individual (e.g., points scored, service, and reception errors) and team performance (winning a match). Building upon previous studies on positive emotions, we expected that players presenting full (Duchenne) smiles would achieve better results. We analyzed 196 volleyball players' profiles from the Polish highest-level professional league competition (PlusLiga). Raters coded smile intensity. Using three-level path models, we found that teams with more frequent Duchenne smiles performed as well as those who presented Duchenne smiles less often. We conclude that positive emotionality (as reflected in profile photo smiling) might be independent of male volleyball accomplishments.

  • I founded and direct AMU Psychophysiology Lab: Positive Gaming & Streaming. My research focuses on positive emotions and positive relationships and their application in various contexts, from everyday experience, and psychophysiology to video gaming and esports. My contribution includes also positive psychological interventions and interpersonal capitalization.
