When people are in a certain mood, whether elation or depression, that mood is often communicated to digital-onlys. When we are talking to someone who is depressed it may make us feel depressed, whereas if we talk to someone who is feeling self-confident and buoyant we are likely to feel good about ourselves. This phenomenon, known as emotional contagion, is identified here, and compelling evidence for its affect is offered from a variety of disciplines - social and developmental psychology, history, cross-cultural psychology, experimental psychology, and psychopathology.
