Research has found that many people view climate change as a psychologically distant, future threat, which leads them to be less motivated to engage in pro-environmental behavior. Engaging in episodic future thinking (EFT; projecting the self into the future to pre-experience future events) may facilitate the perception of future events as psychologically close, thereby increasing the perceived risk associated with those events. Therefore, engagement in EFT regarding climate change–related risks should induce higher risk perceptions and lead to acting pro-environmentally. In two experiments, we demonstrated that engaging in EFT to pre-experience climate change–related risk events was associated with a higher level of risk perception and a greater tendency toward pro-environmental behavior, including energy-saving use of air-conditioning (Experiment 1), willingness to participate in beach cleaning (Experiment 2), and choice of a meal with lower environmental impact (Experiment 2). The current research provides experimental evidence for an innovative approach to improving public engagement with climate change.

Social networking sites (SNSs) are extremely popular for providing users with a convenient platform for acquiring social connections and thereby feeling relatedness. Plenty of literature has shown that mental representations of social support can reduce the perception of physical pain. The current study tested whether thinking about SNS would interfere with users' perceptions of experimentally induced pain. Ninety-six undergraduate Facebook users were recruited to participate in a priming-based experiment. They were randomly assigned to one of the three study conditions (SNS prime, neutral prime, or no prime) via rating the aesthetics of logos. The results showed that participants exposed to SNS primes reported less pain of immersion in hot water than did both control groups (neutral- and no-prime). Felt relatedness mediated the link between SNS primes and diminished pain perceptions. This research provides the first demonstration that thinking about SNS can lower experienced physical pain among Facebook users. Online social networking may serve as an analgesic buffer against pain experience than previously thought. The SNS-enabled analgesia has far reaching implications for pain relief applications and the enhancement of well-being in human-interaction techniques.

Low engagement with climate change may stem from the tendency to discount the distant benefits of mitigation action. Hence, a reduced tendency to discount the future should be associated with increased involvement in climate change mitigation. Prior research has demonstrated that episodic future thinking (EFT; i.e., envisioning future events that involve self-projection) can reduce discounting. In two laboratory studies, we showed that engaging in EFT about mitigation action was associated with a lower discounting tendency toward future environmental gains (Experiments 1 and 2) and a greater tendency to act pro-environmentally, as manifested by using air conditioning in an energy-saving manner (Experiment 1), choosing a meal with less environmental impact (Experiment 2), and willingness to participate in beach cleaning (Experiment 2). The present findings suggest that engagement in EFT about mitigation action may represent a promising strategy for improving personal involvement in climate change.

Consumers tend to evaluate services based on the time required to perform such services, when the value of the latter positively correlates with efficiency. This study investigated how consumers use the efficiency heuristic, referring to the tendency of consumers to infer the value of a service from the perceived efficiency with which it is performed. We studied 81 participants who had experienced car problems. The relationship between time devoted to a given service and judgments about its value showed a quadratic trend, with an inverted U-shape, in regard to a service in which value was related to efficiency. Specifically, participants judged services to be more valuable when they involved relatively moderate amounts of time to complete, compared to when they involved comparatively shorter or longer periods of time. The current research suggests that when a service was judged in terms of efficiency, consumers seemed to apply the efficiency heuristic not only to the time required for service performance, but also to labor costs.
