Emotional contagion

Emotional contagion is a form of social contagion that involves the spontaneous spread of emotions and related behaviors. Such emotional convergence can happen from one person to another, or in a larger group. Emotions can be shared across individuals in many ways, both implicitly or explicitly. For instance, conscious reasoning, analysis, and imagination have all been found to contribute to the phenomenon. The behaviour has been found in humans, other primates, dogs, and chickens.

Emotional contagion contributes to cognitive development initiated in pregnancy. According to a hypothesis of pre-perceptual multimodal integration, the association of affective cues with stimuli responsible for triggering the neuronal pathways of simple reflexes (such as spontaneous blinking, etc.) forms simple neuronal assemblies, shaping the cognitive and emotional neuronal patterns in statistical learning. Empirical evidence showed that cognitive and emotional neuronal patterns are continuously connected with the neuronal pathways of reflexes throughout life.

Emotional contagion is important to personal relationships because it fosters emotional synchrony between individuals. A broader definition of the phenomenon suggested by Schoenewolf is "a process in which a person or group influences the emotions or behavior of another person or group through the conscious or unconscious induction of emotion states and behavioral attitudes." One view developed by Elaine Hatfield, et al., is that this can be done through automatic mimicry and synchronization of one's expressions, vocalizations, postures, and movements with those of another person. When people unconsciously mirror their companions' expressions of emotion, they come to feel reflections of those companions' emotions.

In a 1993 paper, Psychologists Elaine Hatfield, John Cacioppo, and Richard Rapson define emotional contagion as "the tendency to automatically mimic and synchronize expressions, vocalizations, postures, and movements with those of another person's [sic] and, consequently, to converge emotionally".

Hatfield, et al., theorize emotional contagion as a two-step process: First, we imitate people (e.g., if someone smiles at you, you smile back). Second, our own emotional experiences change based on the non-verbal signals of emotion that we give off. For example, smiling makes one feel happier, and frowning makes one feel worse. Mimicry seems to be one foundation of emotional movement between people.

Emotional contagion and empathy share similar characteristics, with the exception of the ability to differentiate between personal and pre-personal experiences, a process known as individuation.^{[clarification needed]} In The Art of Loving (1956), social psychologist Erich Fromm explores these differences, suggesting that autonomy is necessary for empathy, which is not found in emotional contagion.^{[example needed]}

James Baldwin addressed "emotional contagion" in his 1897 work Social and Ethical Interpretations in Mental Development, though using the term "contagion of feeling". Various 20th century scholars discussed the phenomena under the heading "social contagion". The term "emotional contagion" first appeared in Arthur S. Reber's 1985 The Penguin Dictionary of Psychology.

Several factors determine the rate and extent of emotional convergence in a group, including membership stability, mood-regulation norms, task interdependence, and social interdependence. Besides these event-structure properties, there are personal properties of the group's members, such as openness to receive and transmit feelings, demographic characteristics, and dispositional affect that influence the intensity of emotional contagion.
