SUMMARY
The recent expansion of Facebook’s ‘like’ to six emotional reactions (love, haha, wow, sad, angry) represents the first update related to feedback, allowing users to respond to shared content, in almost a decade. We surveyed 260 Facebook users to investigate how reactions are utilized and what type of online content (status updates, pictures, links, timehops and events) they are used to respond to. We also measured Big Five personality and narcissism. Users were most likely to react using like, followed by positive reactions (love, haha, wow), and were least likely to employ the negative reactions sad and angry. Status updates and pictures were the types of content most likely to be responded to, and events least likely. Neuroticism, extraversion and openness positively predicted, and narcissism negatively predicted, utilization of reactions, and likelihood of responding. Results are discussed in relation to established online norms and the affordances of Facebook features.
