From past to present (for a better future): The moderating role of cognitive mindset on spillover effects in environmental behaviors

Research literature about the environmental spillover effect produced mixed results, revealing that an initial pro-environmental behavior (PEB) is likely to promote either other PEBs (i.e., positive spillover) or pro-environmental inactions and harming behaviors (i.e., negative spillover). Such inconsistency suggests a possible crucial role of moderating variables. In two experimental studies (N Study 1 = 141, N Study 2 = 124), we investigated whether the recall of past environmental behavior (water-saving vs. water-wasting) affects future intention to perform PEBs (Study 1) and actual PEBs (Study 2), depending on participants' cognitive mindset (manipulated in Study 1 and measured in Study 2). Results showed that the cognitive mindset is a significant moderator of spillover effects. Compared to a holistic one, an analytical mindset is more likely to result in a greater willingness to engage in future PEBs (Study 1) and actual PEB (Study 2) when past PEB is salient. The main contributions of the studies, limitations and possible future research directions are discussed.
