Emotional communication regulates the behaviors of social partners. Research on individuals' responding to others' emotions typically compares responses to a single negative emotion compared with responses to a neutral or positive emotion. Furthermore, coding of such responses routinely measure surface level features of the behavior (e.g., approach vs. avoidance) rather than its underlying function (e.g., the goal of the approach or avoidant behavior). This investigation examined infants' responding to others' emotional displays across 5 discrete emotions: joy, sadness, fear, anger, and disgust. Specifically, 16-, 19-, and 24-month-old infants observed an adult communicate a discrete emotion toward a stimulus during a naturalistic interaction. Infants' responses were coded to capture the function of their behaviors (e.g., exploration; prosocial behavior; security seeking). The results revealed a number of instances indicating that infants use different functional behaviors in response to discrete emotions. Differences in behaviors across emotions were clearest in the 24-month-old infants, though younger infants also demonstrated some differential use of behaviors in response to discrete emotions. This is the first comprehensive study to identify differences in how infants respond with goal-directed behaviors to discrete emotions. Additionally, the inclusion of a function-based coding scheme and interpersonal paradigms may be informative for future emotion research with children and adults. Possible developmental accounts for the observed behaviors and the benefits of coding techniques emphasizing the function of social behavior over their form are discussed.

Social referencing informs and regulates one's relation with the environment as a function of the perceived appraisals of social partners. Increased emphasis on relational and social contexts in the study of emotion makes this interpersonal process particularly relevant to the field. However, theoretical conceptualizations and empirical operationalizations of social referencing are disjointed across domains and populations of study. This article seeks to unite and refine the study of this construct by providing a clear and comprehensive definition of social referencing. Our perspective presents social referencing and social appraisal as coterminous processes and emphasizes the importance of a relational and interpersonal approach to the study of emotion. We conclude by outlining possible lines of research on this construct.

Do children and adults engage in spontaneous Theory of Mind (ToM)? Accumulating evidence from anticipatory looking (AL) studies suggests that they do. But a growing body of studies failed to replicate these original findings. This paper presents the first step of a large-scale multi-lab collaboration dedicated to testing the robustness of spontaneous ToM measures. It examines whether 18-27-month-olds and adults’ anticipatory looks distinguish between knowledgeable and ignorant agents. In a pre-registered study with toddlers [anticipated N = 440, 50% female] and adults [anticipated N = 360, 50% female] from diverse ethnic backgrounds, we found that [DESCRIBE RESULT AND EFFECT SIZE FOR MAIN CONFIRMATORY ANALYSIS].

ABSTRACT-Understanding emotion in interpersonal contexts involves appreciating others' relations with the environment. This ability is related fundamentally to social cognition, including understanding the actions and goals of social partners. However, the significance of infants' emotion understanding has been largely underemphasized in recent studies on infants' social-cognitive development. In this review, we highlight the interconnectedness of emotion understanding and social cognition in socioemotional development. We incorporate a relational view of emotion to bridge empirical and theoretical work on emotional and social-cognitive development, and to demonstrate the utility of this approach for advancing novel areas of inquiry.

Emotion can be communicated through multiple distinct modalities. However, an often-ignored channel of communication is posture. Recent research indicates that bodily posture plays an important role in the perception of emotion. However, research examining postural communication of emotion is limited by the variety of validated emotion poses and unknown cohesion of categorical and dimensional ratings. The present study addressed these limitations. Specifically, we examined individuals’ (1) categorization of emotion postures depicting 5 discrete emotions (joy, sadness, fear, anger, and disgust), (2) categorization of different poses depicting the same discrete emotion, and (3) ratings of valence and arousal for each emotion pose. Findings revealed that participants successfully categorized each posture as the target emotion, including disgust. Moreover, participants accurately identified multiple distinct poses within each emotion category. In addition to the categorical responses, dimensional ratings of valence and arousal revealed interesting overlap and distinctions between and within emotion categories. These findings provide the first evidence of an identifiable posture for disgust and instantiate the principle of equifinality of emotional communication through the inclusion of distinct poses within emotion categories. Additionally, the dimensional ratings corroborated the categorical data and provide further granularity for future researchers to consider in examining how distinct emotion poses are perceived.
