The Limits of Cognitive Reappraisal: Changing Pain Valence, but not Persistence, during a Resistance Exercise Task.

Physiological discomfort is commonly cited as a barrier for initiating and persisting with exercise. Although individuals may think of physiological discomfort as determined by physical sensations, it can also be influenced by cognitive and emotional factors. We explored the impacts of interpreting the purpose of pain as a sign of muscle building (helpful) vs. a sign of muscle tearing and possible injury (harmful) and tested the effect of cognitive reappraisals, or shifting interpretations of pain, on exercise persistence and the subjective experience of discomfort during exercise. Seventy-eight participants were randomized to listen to voice recordings that framed exercise-related pain as helpful vs. harmful before participating in a standard muscular endurance test using the YMCA protocol. Although the two experimental groups did not differ in the overall number of resistance training repetitions achieved, participants who were asked to think about the benefits (rather than the negative consequences) of pain reported less negative pain valence during exercise. Thus, the experience of pain was influenced by appraisals of the meaning of pain, but differences in pain valence did not impact exercise persistence. Theoretical implications and applications for affect-based exercise interventions are discussed.

Impact of Disgust on Intentions to Undergo Colorectal Surgery.

BACKGROUND: Surgeons present patients with complex information at the perioperative appointment. Emotions likely play a role in surgical decision-making, and disgust is an emotion of revulsion at a stimulus that can lead to avoidance. OBJECTIVE: The purpose of this study was to determine the impact of disgust on intention to undergo surgical resection for colorectal cancer and recall of perioperative instructions. DESIGN: This was a cross-sectional observational study conducted online using hypothetical scenarios with nonpatient subjects. SETTINGS: The study was conducted using Amazon's Mechanical Turk. PATIENTS: Survey respondents were living in the United States. MAIN OUTCOME MEASURES: Surgery intention and recall of perioperative instructions were measured. RESULTS: A total of 319 participants met the inclusion criteria. Participants in the experimental condition, who were provided with detailed information and pictures about stoma care, had significantly lower surgery intentions (mean ± SD, 4.60 ± 1.15) compared with the control condition with no stoma prompt (mean ± SD, 5.14 ± 0.91; p = 0.05) and significantly lower recall for preoperative instructions (mean ± SD, 13.75 ± 2.38) compared with the control condition (mean ± SD, 14.36 ± 2.19; p = 0.03). Those within the experimental conditions also reported significantly higher state levels of disgust (mean ± SD, 4.08 ± 1.74) compared with a control condition (mean ± SD, 2.35 ± 1.38; p < 0.001). State-level disgust was found to fully mediate the relationship between condition and recall (b = -0.31) and to partially mediate the effect of condition on surgery intentions (b = 0.17). LIMITATIONS: It is unknown whether these results will replicate with patients and the impact of competing emotions in clinical settings. CONCLUSIONS: Intentions to undergo colorectal surgery and recall of preoperative instructions are diminished in patients who experience disgust when presented with stoma information. Surgeons and care teams must account for this as they perform perioperative counseling to minimize interference with recall of important perioperative information.

Naïve models of dietary splurges: Beliefs about caloric compensation and weight change following non-habitual overconsumption.

The mechanisms that lead to overeating and the consumption of tempting, unhealthy foods have been studied extensively, but the compensatory actions taken afterwards have not. Here we describe the naïve models individuals hold around dietary splurges (single bouts of overeating) and associated weight changes. Across six online experiments, we found that, following a hypothetical dietary splurge, participants did not plan to adequately adjust calorie consumption to account for the additional calories consumed (Studies 1 and 2), and this pattern was worse following hypothetical splurges characterized by a large amount of food consumed in a single bout (Study 3). Participants expected weight changes to happen faster than they do in reality (Study 4) and they expected that weight gained from a dietary splurge would disappear on its own without explicit compensation attempts through diet or exercise (Study 5). Similarly, participants expected that when compensation attempts were made through calorie restriction, the rate of weight loss would be faster following a dietary splurge compared to normal eating (Study 6). This research contributes novel data demonstrating an important mechanism that likely contributes to weight gain and failed weight loss attempts.

The critical role of second-order normative beliefs in predicting energy conservation.

Sustaining large-scale public goods requires individuals to make environmentally friendly decisions today to benefit future generations1-6. Recent research suggests that second-order normative beliefs are more powerful predictors of behaviour than first-order personal beliefs7,8. We explored the role that second-order normative beliefs-the belief that community members think that saving energy helps the environment-play in curbing energy use. We first analysed a data set of 211 independent, randomized controlled trials conducted in 27 US states by Opower, a company that uses comparative information about energy consumption to reduce household energy usage (pooled N = 16,198,595). Building off the finding that the energy savings varied between 0.81% and 2.55% across states, we matched this energy use data with a survey that we conducted of over 2,000 individuals in those same states on their first-order personal and second-order normative beliefs. We found that second-order normative beliefs predicted energy savings but first-order personal beliefs did not. A subsequent pre-registered experiment provides causal evidence for the role of second-order normative beliefs in predicting energy conservation above first-order personal beliefs. Our results suggest that second-order normative beliefs play a critical role in promoting energy conservation and have important implications for policymakers concerned with curbing the detrimental consequences of climate change.
