Zelenski's research focuses on emotions, especially individual differences in emotional experience, and the role emotions play in modulating cognition. The topic of happiness unifies his primary research questions. At a descriptive level, he asks the question, who is happy? That is, what are the personality characteristics that predict the experience of many positive emotions and few negative emotions? At a process level, he asks, how do happy people think and behave differently than unhappy people? In other words, how do transient mood states and stable individual differences combine to influence cognitive processes and behaviour? Finally, at the level of personality theory, he seeks to understand what ’causes’ the traits associated with happiness? That is, how do individual differences play out ‘in the moment’ and combine with situational factors to predict behaviour?
Much of this work focuses on extraversion, positive emotions, and social behaviour. Another line of research investigates differences in people’s sense of connection to nature (‘nature relatedness’) and links this to happiness and environmentally responsible behaviours.
