ABSTRACT

The use of autoclitics can influence the behavior of individuals making choices when responding to a survey (e.g., checking or unchecking a box). In two studies, we investigated the effects of autoclitics as "nudges" on choice by manipulating different frames (opt-in and opt-out) and default options (i.e., unchecked and checked boxes). Undergraduate students recruited from behavioral science courses engaged with materials in the study. In study 1, we used an online survey at the beginning of the semester offering the choice of whether to enroll in extra-academic activities (i.e., practice tests) available via the online course platform, Blackboard. We randomly assigned students into one of four groups: 1) option to enroll with an unchecked box, 2) option to not enroll with an unchecked box, 3) option to enroll with a checked box, or 4) option to not enroll with a checked box. Results showed that the option to not enroll with an unchecked box produced higher enrollment to receive extra academic activities. In the middle of the semester, we conducted a within-subject arrangement wherein students who initially opted out of receiving activities had the option to accept them following exposure to the negative autoclitic frame. Most of these students opted into receiving activities. In study 2, we replicated the methods of study 1 in Canvas, a different course platform, and obtained similar results. We briefly discuss the implications of a nudge for ethical consent.

ABSTRACT

The stability of stimulus preference assessment results is an important consideration when using the identified stimuli in treatments and/or additional experiments. Prior research has demonstrated that the preference hierarchies identified by the multiple stimulus without replacement (MSWO) preference assessment are generally stable over time. This stability has been demonstrated with tangible and edible items, yet the extent to which that stability can be expected for other types of stimuli remains unknown. The current study tested the 2-month stability of the MSWO preference assessment in the context of college students' preferred sexual partners. Adequate stability was shown in most cases, suggesting generality of the stability of preference across tasks, populations, and stimuli.

ABSTRACT

The role of human behavior to thwart transmission of infectious diseases like COVID-19 is evident. Psychological and behavioral science are key areas to understand decision-making processes underlying engagement in preventive health behaviors. Here we adapt well validated methods from behavioral economic discounting and demand frameworks to evaluate variables (e.g., delay, cost, probability) known to impact health behavior engagement. We examine the contribution of these mechanisms within a broader response class of behaviors reflecting adherence to public health recommendations made during the COVID-19 pandemic. Four crowdsourced samples (total N = 1,366) completed individual experiments probing a response class including social (physical) distancing, facemask wearing, COVID-19 testing, and COVID-19 vaccination. We also measure the extent to which choice architecture manipulations (e.g., framing, opt-in/opt-out) may promote (or discourage) behavior engagement. We find that people are more likely to socially distance when specified activities are framed as high risk, that facemask use during social interaction decreases systematically with greater social relationship, that describing delay until testing (rather than delay until results) increases testing likelihood, and that framing vaccine safety in a positive valence improves vaccine acceptance. These findings collectively emphasize the flexibility of methods from diverse areas of behavioral science for informing public health crisis management.

ABSTRACT

The role of human behavior to thwart transmission of infectious diseases like COVID-19 is evident. Yet, many areas of psychological and behavioral science are limited in the ability to mobilize to address exponential spread or provide easily translatable findings for policymakers. Here we describe how integrating methods from operant and cognitive approaches to behavioral economics can provide robust policy relevant data. Adapting well validated methods from behavioral economic discounting and demand frameworks, we evaluate in four crowdsourced samples (total N = 1,366) behavioral mechanisms underlying engagement in preventive health behaviors. We find that people are more likely to social distance when specified activities are framed as high risk, that describing delay until testing (rather than delay until results) increases testing likelihood, and that framing vaccine safety in a positive valence improves vaccine acceptance. These findings collectively emphasize the flexibility of methods from diverse areas of behavioral science for informing public health crisis management.

ABSTRACT

OBJECTIVES: Although cocaine use has been linked to sexual HIV risk behavior for decades, the direct effects of cocaine on sexual desire and sexual decision-making are unexamined. Research suggests delay discounting (devaluation of future outcomes) and probability discounting (devaluation of uncertain outcomes) play roles in condom use decisions. This study examined the effect of cocaine administration on sexual desire, hypothetical condom use, and discounting tasks. METHODS: This double-blind, within-subjects study compared the effects of 0, 125, and 250 mg/70 kg oral cocaine HCl in 12 cocaine users. Measures included sexual desire and other subjective ratings, the Sexual Delay Discounting Task, the Sexual Probability Discounting Task, and monetary delay and probability discounting tasks. RESULTS: Cocaine caused dose-related increases in sexual desire and prototypical stimulant abuse-liability ratings. Relative to placebo, cocaine did not significantly alter condom use likelihood when condoms were immediately available or when sex was associated with 100% certainty of sexually transmitted infection (STI). In contrast, cocaine dose-dependently strengthened the effect of delay (sexual delay discounting) and STI uncertainty (sexual probability discounting) in decreasing condom use likelihood. Cocaine caused no significant change in monetary delay and probability discounting. CONCLUSION: This is the first study showing that cocaine administration increases sexual desire. Detrimental effects of cocaine on sexual risk were only observed when safer sex required delay, or STI risk was uncertain (representative of many real-world scenarios), suggesting a critical role of discounting processes. Lack of monetary effects highlights the importance of studying clinically relevant outcomes when examining drug effects on behavioral processes.
