This article examines the dynamics of conditional choice as a mechanism for explaining social action, with particular emphasis on identifying model frameworks for the analysis of the trajectory and outcome of conditional decision-making processes. It begins with an overview of conditional decision-making, including key words and concepts, followed by a discussion of conditional decision rules and initial states of activity and how they shape the basic trajectory and outcome of a conditional decision-making process. It then considers possible sources of resistance to influence, focusing on the ways unconditional actors pull all other group members towards their position and how individual variation in resistance to influence can stop a process from reaching complete conformity. It also explores patterns of social interaction and how they work in combination with resistance to influence to account for variation in activity among individuals or groups, paying attention to the contingent effect of local networks.

Objective: One in four college women experience sexual assault on campus. Campuses rarely provide the in depth self-defense programs needed to reduce sexual assault risk. Not much is known about the range of possible behaviors elicited by sexual assault threat stimuli besides assertion. To fill this gap, the aim of the current study was to explore qualitative themes in women’s intended behavioral responses to a hypothetical common sexual assault threat, date rape, by using a laboratory controlled threat. Methods: College women (N = 139) were randomly assigned to one of four different levels of sexual assault threat presented via an audio recorded vignette. Participants articulated how they would hypothetically respond to the experimentally assigned threat. Responses were blinded and analyzed using Consensual Qualitative Research methodology. Results: Six major themes emerged: assertion, compliance/acceptance, conditional decision-making, avoidance, expressions of discomfort, and allusion to future contact. Although almost all participants described assertion, a number of non-assertive responses were described that are not currently recognized in the literature. These non-assertive responses, including compliance/acceptance, conditional decision making, and avoidance may represent unique behavioral response styles and likely reflect the complex psychological process of behavioral response to threat. Discussion: The variety of themes found illustrates the great range of behavioral responses to threat. This broad range is not currently well represented or measured in the literature and better understanding of these responses can inform future interventions, advocacy efforts, and policies focused on sexual assault.

AbstractRahnev & Denison (R&D) argue against normative theories and in favor of a more descriptive “standard observer model” of perceptual decision making. We agree with the authors in many respects, but we argue that optimality (specifically, reward-rate maximization) has proved demonstrably useful as a hypothesis, contrary to the authors’ claims.

AbstractThe target article uses a mathematical framework derived from Bayesian decision making to demonstrate suboptimal decision making but then attributes psychological reality to the framework components. Rahnev & Denison's (R&D) positive proposal thus risks ignoring plausible psychological theories that could implement complex perceptual decision making. We must be careful not to slide from success with an analytical tool to the reality of the tool components.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
