Emotion differentiation captures the detail with which people describe their emotional experiences. A compelling body of research has linked low and negative emotion differentiation to a host of adverse psychological outcomes, yet conceptual and methodological questions and issues remain. We think that the time is right to review and reflect on this growing literature to gain clarity that can be applied to future research. We first review assessment of emotion differentiation while highlighting the methodological variation across studies. Then supported by the literature review, we discuss disconnections between the conceptualization and measurement of differentiation. Finally, to motivate future research, we propose factors that we hypothesize are associated with potentially beneficial effects of emotion differentiation in a given situation (i.e., related to state emotion differentiation) and more generally across time (i.e., related to trait emotion differentiation).

Interpersonal goals and adult attachment have implications for how people interact with others as well as for emotion experience and regulation. Literature on intrapersonal emotional processes has typically not examined motivations underlying people's engagement with others’ emotions and its connections to individual differences related to close relationships such as attachment. This study analyzed the relationships between interpersonal emotion regulation motives, perceived social interaction outcomes, and attachment. Undergraduates (N = 211) reported their trait attachment. Experience sampling was used to examine the reasons why they wanted to regulate others’ emotions during daily interactions and perceived changes in their own well-being and relationship quality with the target of regulation. Attachment anxiety was associated with more self-focused prohedonic motives and impression management motives, while attachment avoidance predicted less perceived increases in emotional and relational well-being after interactions. People who tended to report more (self- and other-focused) prohedonic and less impression management motives in daily life perceived more positive changes in their emotional well-being and people who tended to report higher emotional similarity motives perceived more positive changes in their relational well-being after interactions People also perceived more positive emotional and relational interaction outcomes at times when they held more (self- and other-focused) prohedonic, impression management, or relationship maintenance motives and less self-focused performance and relationship distancing motives. Overall, these findings suggest that attachment anxiety may guide why people engage with other people’s emotions and these extrinsic interpersonal emotion regulation motives may play a role in socioemotional outcomes of daily interactions.

Aims: Athletes in the general population report higher satisfaction of basic needs when coaches are providing an autonomy supportive sport climate (ASSC). Our study aims at investigating whether ASSC is associated with satisfaction with life in athletes with intellectual disabilities (ID) and whether this association is mediated by basic need satisfaction. Method: During the Special Olympics World Winter Games 2017, 168 athletes with ID (M ¼ 33.86 years; SD ¼ 10.47) completed questionnaires measuring ASSC, basic need satisfaction (autonomy, competence, and relatedness), and satisfaction with life. Multiple linear regression analyses and mediation analyses were performed. The mediation model was controlled for the potential impact of participating in team vs. individual sports. Additionally, gender effects were explored. Results: ASSC was significantly associated with satisfaction with life (b ¼ .38, p < .001). This association was mediated by competence (indirect effect: ab 1 ¼ .15; CI [.05; .32]) but not by autonomy or relatedness. No effects were found related to participating in team vs. individual sports or gender. Conclusions: Our study provides evidence that an ASSC is associated with athletes perceiving themselves as more competent and reporting more satisfaction with life.

How do people come to know others' feelings? One idea is that affective processes (e.g., physiological responses) play an important role, leading to the prediction that linkage between one's physiological responses and others' emotions relates to one's ability to know how others feel (i.e., empathic accuracy). Participants (N = 96, 48 female friend pairs) completed a stressful speech task and then provided continuous ratings of their own (as "targets") and their friend's (as "perceivers") emotional experience for the video-taped speeches. We measured physiology-physiology linkage (linkage between perceivers' and targets' physiology), physiology-experience linkage (linkage between perceivers' physiology and targets' experience), and empathic accuracy (linkage between perceivers' ratings of targets' experience and targets' ratings of their experience). Physiology-experience (but not physiology-physiology) linkage was associated with greater empathic accuracy even when controlling for key potential confounds (random linkage, targets' and perceivers' emotional reactivity, and relationship closeness). Results suggest that physiological responses play a role in empathic accuracy.
