RESUMO

A promising way to mitigate inequality is by addressing students' worries about belonging. But where and with whom is this social-belonging intervention effective? Here we report a team-science randomized controlled experiment with 26,911 students at 22 diverse institutions. Results showed that the social-belonging intervention, administered online before college (in under 30 minutes), increased the rate at which students completed the first year as full-time students, especially among students in groups that had historically progressed at lower rates. The college context also mattered: The intervention was effective only when students' groups were afforded opportunities to belong. This study develops methods for understanding how student identities and contexts interact with interventions. It also shows that a low-cost, scalable intervention generalizes its effects to 749 4-year institutions in the United States.

RESUMO

Reports an error in "Harnessing the placebo effect: Exploring the influence of physician characteristics on placebo response" by Lauren C. Howe, J. Parker Goyer and Alia J. Crum (Health Psychology, 2017[Nov], Vol 36[11], 1074-1082). In the original article, changes were needed to clarify the timeframe over which allergic reactions were measured after the skin prick test (SPT) and the administration of the placebo cream, which was erroneously misrepresented in some cases being "0 to 6 minutes after cream application" when it should have stated "3 to 9 minutes after cream application." Corrections have been made to reflect this in the "Analytic Strategy for Physiological Results" section and in Figures 2 and 3 and the Figure Notes that accompany them. An additional supplemental figure (Figure S7) has also been added to the supplemental material available online to further clarify the timing of measurements, both in terms of time post-SPT and time post-cream application. The online version of this article has been corrected. (The following abstract of the original article appeared in record 2017-10534-001). OBJECTIVE: Research on placebo/nocebo effects suggests that expectations can influence treatment outcomes, but placebo/nocebo effects are not always evident. This research demonstrates that a provider's social behavior moderates the effect of expectations on physiological outcomes. METHODS: After inducing an allergic reaction in participants through a histamine skin prick test, a health care provider administered a cream with no active ingredients and set either positive expectations (cream will reduce reaction) or negative expectations (cream will increase reaction). The provider demonstrated either high or low warmth, or either high or low competence. RESULTS: The impact of expectations on allergic response was enhanced when the provider acted both warmer and more competent and negated when the provider acted colder and less competent. CONCLUSION: This study suggests that placebo effects should be construed not as a nuisance variable with mysterious impact but instead as a psychological phenomenon that can be understood and harnessed to improve treatment outcomes.

RESUMO

Suspensions remove students from the learning environment at high rates throughout the United States. Policy and theory highlight social groups that face disproportionately high suspension rates-racial-minoritized students, students with a prior suspension, and students with disabilities. We used an active placebo-controlled, longitudinal field experiment (Nteachers = 66, Nstudents = 5822) to test a scalable "empathic-mindset" intervention, a 45- to 70-min online exercise to refocus middle school teachers on understanding and valuing the perspectives of students and on sustaining positive relationships even when students misbehave. In preregistered analyses, this exercise reduced suspension rates especially for Black and Hispanic students, cutting the racial disparity over the school year from 10.6 to 5.9 percentage points, a 45% reduction. Significant reductions were also observed for other groups of concern. Moreover, reductions persisted through the next year when students interacted with different teachers, suggesting that empathic treatment with even one teacher in a critical period can improve students' trajectories through school.

RESUMO

Nearly all students experience stress as they pursue important academic goals. Because stress can be magnified for students from disadvantaged backgrounds, it becomes important to identify interventions that can help mitigate this stress, particularly for these populations as they enter academic environments. We examine the effects of stress mindset and stress management interventions administered to students from disadvantaged backgrounds (N = 140) before freshman year. We compare effects on affect, sleep, and performance during end-of-year exams seen in a subset of these students who could be tracked via experience sampling (N = 57) to those of a comparison group at the same elite university (N = 74) receiving no such stress interventions. As predicted, we find significant differences in exam-week positive affect between the stress mindset and comparison groups. However, there was no difference in positive affect between the stress mindset and management groups or the stress management and comparison groups. For negative affect, stress, sleep, and exam performance, we find no significant differences between any of the three groups. However, both stress interventions decoupled the significant negative association between exam-week stress and exam performance exhibited by the comparison group, rendering the relationship nonsignificant. The reduction in this association was somewhat more pronounced for the mindset relative to the management group. These findings suggest that mindset and management approaches both confer benefits in certain circumstances and highlight the potential value of targeting mindsets about stress using a "wise intervention" approach for students from disadvantaged backgrounds during stressful times.

RESUMO

Developmental systems theory and life span development describe the role of individual-context interactions in individual development but have not directly addressed how individuals pursue achievement goals in institutional contexts. We developed a theory informed by these perspectives that explains how institutional contexts affect emerging adults' success in transitioning to and progressing through college. We theorize that institutional contexts increase individuals' probability of attaining specific goals when they provide stronger channels that offer more versus fewer structural supports for these goals. Moreover, we theorize, these institutional channels influence which individual differences, including belonging certainty, growth mindset of intelligence, and grit, will be useful in goal pursuit, above and beyond individuals' academic preparation and demographic factors. We examined postsecondary goal pursuit over a 6-year period among 1,850 students who attended one of four district high schools in Pennsylvania or Massachusetts. On average, they began the study at 17.91 years of age; 48% were male, 43% belonged to a historically marginalized ethnicity, and 56% had free or reduced lunch status. We found that channel strength and psychological factors interacted in ways predicted by our theory. Higher belonging certainty and growth mindset in Grade 12, which encourage a focus on process and progress, predicted better outcomes in weaker postsecondary channels, especially college enrollment and on-track progress. Higher grit, which encourages a commitment to goal attainment, predicted better outcomes in stronger postsecondary channels, especially on-time graduation. The study locates the importance of psychological factors in predicting goal attainment in different-strength institutional channels during emerging adulthood.

RESUMO

Millions of people now access personal genetic risk estimates for diseases such as Alzheimer's, cancer and obesity1. While this information can be informative2-4, research on placebo and nocebo effects5-8 suggests that learning of one's genetic risk may evoke physiological changes consistent with the expected risk profile. Here we tested whether merely learning of one's genetic risk for disease alters one's actual risk by making people more likely to exhibit the expected changes in gene-related physiology, behaviour and subjective experience. Individuals were genotyped for actual genetic risk and then randomly assigned to receive either a 'high-risk' or 'protected' genetic test result for obesity via cardiorespiratory exercise capacity (experiment 1, N = 116) or physiological satiety (experiment 2, N = 107) before engaging in a task in which genetic risk was salient. Merely receiving genetic risk information changed individuals' cardiorespiratory physiology, perceived exertion and running endurance during exercise, and changed satiety physiology and perceived fullness after food consumption in a self-fulfilling manner. Effects of perceived genetic risk on outcomes were sometimes greater than the effects associated with actual genetic risk. If simply conveying genetic risk information can alter actual risk, clinicians and ethicists should wrestle with appropriate thresholds for when revealing genetic risk is warranted.

RESUMO

OBJECTIVE: Recent research on open-label placebos, or placebos administered without deception or concealment, suggests that they can be effective in a variety of conditions. The current research sought to unpack the mechanisms underlying the treatment efficacy of open-label placebos. METHOD: A health care provider induced an allergic reaction in 148 participants via a histamine skin prick test. Participants were then exposed to 1 of 4 conditions additively leveraging various mechanisms of open-label placebo treatments: a supportive patient-provider relationship, a medical ritual, positive expectations, and a rationale about the power of placebos. RESULTS: There were no main effects of condition on allergic responses. However, participant beliefs about placebos moderated the effect of open-label placebo treatment condition on physiological allergic reactions: the condition including all 4 components of open-label placebos (a supportive patient-provider relationship, a medical ritual, positive expectations, and a rationale about the power of placebos) significantly reduced physiological allergic reaction among participants with a strong belief in placebos compared with participants in the control group. CONCLUSION: Participants' beliefs about placebos interact with information from the provider to reduce physiological allergic reactions in response to an open-label placebo treatment. This study underscores the importance of measuring and understanding how participants' beliefs influence outcomes of treatment, and furthers our understanding of when and how open-label placebo treatments work.

RESUMO

High rates of discipline citations predict adverse life outcomes, a harm disproportionately borne by Black and Latino boys. We hypothesized that these citations arise in part from negative cycles of interaction between students and teachers, which unfold in contexts of social stereotypes. Can targeted interventions to facilitate identity safety-a sense of belonging, inclusion, and growth-for students help? Experiment 1 combined social-belonging, values-affirmation, and growth-mindset interventions delivered in several class sessions in 2 middle schools with a large Latino population (N = 669). This treatment reduced citations among negatively stereotyped boys in 7th and 8th grades by 57% as compared with a randomized control condition, 95% CI [-77%, -20%]. A growth-mindset only treatment was also effective (70% reduction, 95% CI [-84%, -43%]). Experiment 2 tested the social-belonging intervention alone, a grade earlier, at a third school with a large Black population and more overall citations (N = 137 sixth-grade students). In 2 class sessions, students reflected on stories from previous 7th-grade students, which represented worries about belonging and relationships with teachers early in middle school as normal and as improving with time. This exercise reduced citations among Black boys through the end of high school by 65%, 95% CI [-85%, -15%], closing the disparity with White boys over 7 years by 75%. Suggesting improved interactions with teachers, longitudinal analyses found that the intervention prevented rises in citations involving subjective judgments (e.g., "insubordination") within 6th and 7th grades. It also forestalled the emergence of worries about being seen stereotypically by the end of 7th grade. Identity threat can give rise to cycles of interaction that are maladaptive for both teachers and students in school; targeted exercises can interrupt these cycles to improve disciplinary outcomes over years.

RESUMO

Achieving important goals is widely assumed to require confronting obstacles, failing repeatedly, and persisting in the face of frustration. Yet empirical evidence linking achievement and frustration tolerance is lacking. To facilitate work on this important topic, we developed and validated a novel behavioral measure of frustration tolerance: the Mirror Tracing Frustration Task (MTFT). In this 5-min task, participants allocate time between a difficult tracing task and entertaining games and videos. In two studies of young adults (Study 1: N = 148, Study 2: N = 283), we demonstrated that the MTFT increased frustration more than 18 other emotions, and that MTFT scores were related to self-reported frustration tolerance. Next, we assessed whether frustration tolerance correlated with similar constructs, including self-control and grit, as well as objective measures of real-world achievement. In a prospective longitudinal study of high-school seniors (N = 391), MTFT scores predicted grade-point average and standardized achievement test scores, and-more than 2 years after completing the MTFT-progress toward a college degree. Though small in size (i.e., rs ranging from .10 to .24), frustration tolerance predicted outcomes over and above a rich set of covariates, including IQ, sociodemographics, self-control, and grit. These findings demonstrate the validity of the MTFT and highlight the importance of frustration tolerance for achieving valued goals. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

RESUMO

BACKGROUND: The dominant perspective in society is that stress has negative consequences, and not surprisingly, the vast majority of interventions for coping with stress focus on reducing the frequency or severity of stressors. However, the effectiveness of stress attenuation is limited because it is often not possible to avoid stressors, and avoiding or minimizing stress can lead individuals to miss opportunities for performance and growth. Thus, during stressful situations, a more efficacious approach is to optimize stress responses (i.e., promote adaptive, approach-motivated responses). Objectives and Conclusions: In this review, we demonstrate how stress appraisals (e.g., [Jamieson, J. P., Nock, M. K., & Mendes, W. B. (2012). Mind over matter: reappraising arousal improves cardiovascular and cognitive responses to stress. Journal of Experimental Psychology: General, 141(3), 417-422. doi: 10.1037/a0025719 ]) and stress mindsets (e.g., [Crum, A. J., Salovey, P., & Achor, S. (2013). Rethinking stress: The role of mindsets in determining the stress response. Journal of Personality and Social Psychology, 104(4), 716-733. doi: 10.1037/a0031201 ]) can be used as regulatory tools to optimize stress responses, facilitate performance, and promote active coping. Respectively, these interventions invite individuals to (a) perceive stress responses as functional and adaptive, and (b) see the opportunity inherent in stress. We then propose a novel integration of reappraisal and mindset models to maximize the utility and effectiveness of stress optimization. Additionally, we discuss future directions with regard to how stress responses unfold over time and between people to impact outcomes in the domains of education, organizations, and clinical science.

RESUMO

Fostering perceptions of group malleability (teaching people that groups are capable of change and improvement) has been shown to lead to short-term improvements in intergroup attitudes and willingness to make concessions in intractable conflicts. The present study, a field intervention involving 508 Israelis from three locations in Israel, replicated and substantially extended those findings by testing the durability of a group malleability intervention during a 6-month period of frequent violence. Three different 5-hour-long interventions were administered as leadership workshops. The group malleability intervention was compared with a neutral coping intervention and, importantly, with a state-of-the-art perspective-taking intervention. The group malleability intervention proved superior to the coping intervention in improving attitudes, hope, and willingness to make concessions, and maintained this advantage during a 6-month period of intense intergroup conflict. Moreover, it was as good as, and in some respects superior to, the perspective-taking intervention. These findings provide a naturalistic examination of the potential of group malleability interventions to increase openness to conflict resolution.

RESUMO

Small but timely experiences can have long-term benefits when their psychological effects interact with institutional processes. In a follow-up of two randomized field experiments, a brief values affirmation intervention designed to buffer minority middle schoolers against the threat of negative stereotypes had long-term benefits on college-relevant outcomes. In study 1, conducted in the Mountain West, the intervention increased Latino Americans' probability of entering a college readiness track rather than a remedial one near the transition to high school 2 y later. In study 2, conducted in the Northeast, the intervention increased African Americans' probability of college enrollment 7-9 y later. Among those who enrolled in college, affirmed African Americans attended relatively more selective colleges. Lifting a psychological barrier at a key transition can facilitate students' access to positive institutional channels, giving rise to accumulative benefits.

RESUMO

This paper investigates how social influence can alter physiological, psychological, and functional responses to a placebo product and how such responses influence the ultimate endorsement of the product. Participants consumed a product, "AquaCharge Energy Water," falsely-labeled as containing 200 mg of caffeine but which was actually plain spring water, in one of three conditions: a no social influence condition, a disconfirming social influence condition, and a confirming social influence condition. Results demonstrated that the effect of the product labeling on physiological alertness (systolic blood pressure), psychological alertness (self-reported alertness), functional alertness (cognitive interference), and product endorsement was moderated by social influence: participants experienced more subjective, physiological and functional alertness and stronger product endorsement when they consumed the product in the confirming social influence condition than when they consumed the product in the disconfirming social influence condition. These results suggest that social influence can alter subjective, physiological, and functional responses to a faux product, in this case transforming the effects of plain water.
