A large body of research has investigated responses to artificial scenarios (e.g., trolley problem) where maximizing beneficial outcomes for the greater good (utilitarianism) conflicts with adherence to moral norms (deontology). The CNI model is a computational model that quantifies sensitivity to consequences for the greater good ( C), sensitivity to moral norms ( N), and general preference for inaction versus action ( I) in responses to plausible moral dilemmas based on real-world events. Expanding on a description of the CNI model, the current article provides (a) a comprehensive review of empirical findings obtained with the CNI model, (b) an analysis of their theoretical implications, (c) a discussion of criticisms of the CNI model, and (d) an overview of alternative approaches to disentangle multiple factors underlying moral-dilemma responses and the relation of these approaches to the CNI model. The article concludes with a discussion of open questions and new directions for future research. Public AbstractHow do people make judgments about actions that violate moral norms yet maximize the greater good (e.g., sacrificing the well-being of a small number of people for the well-being of a larger number of people)? Research on this question has been criticized for relying on highly artificial scenarios and for conflating multiple distinct factors underlying responses in moral dilemmas. The current article reviews research that used a computational modeling approach to disentangle the roles of multiple distinct factors in responses to plausible moral dilemmas based on real-world events. By disentangling sensitivity to consequences, sensitivity to moral norms, and general preference for inaction versus action in responses to realistic dilemmas, the reviewed work provides a more nuanced understanding of how people make judgments about the right course of action in moral dilemmas.more » « less

Research suggests that evaluations of an object can be jointly influenced by (a) the mere co-occurrence of the object with a pleasant or unpleasant stimulus (e.g., mere co-occurrence of object A and negative event B) and (b) the object’s specific relation to the co-occurring stimulus (e.g., object A starts vs. stops negative event B). Three experiments investigated the impact of cognitive load during learning on the effects of stimulus co-occurrence and stimulus relations. Counter to the shared prediction of competing theories suggesting that effects of stimulus relations should be reduced by cognitive load during learning, effects of stimulus relations were greater (rather than smaller) under high-load compared with low-load conditions. Effects of stimulus co-occurrence were not significantly affected by cognitive load. The results are discussed in terms of theories suggesting that cognitive load can influence behavioral outcomes via strategic shifts in resource allocation in response to task-specific affordances.more » « less

Research suggests that evaluations of an object can be simultaneously influenced by (a) the mere co-occurrence of the object with a pleasant or unpleasant stimulus (e.g., mere co-occurrence of object A and negative event B) and (b) the object’s particular relation to the co-occurring stimulus (e.g., object A starts vs. stops negative event B). Using a multinomial modeling approach to disentangle the two kinds of influences on choice decisions, three experiments investigated whether learners can intentionally control the relative impact of stimulus co-occurrence and stimulus relations. An integrative analysis of the data from the three experiments ( N = 1,154) indicate that incentivized instructions to counteract effects of stimulus co-occurrence by focusing on stimulus relations increased the impact of stimulus relations without affecting the impact of stimulus co-occurrence. Implications for evaluative learning, intentional control, and public policy are discussed.more » « less
