Project description:The misinformation effect is one of the major threats for the quality of witness testimony. It involves including of information that is inconsistent with the course of an event, and which originates from sources other than the event itself, into a witness's report of the event. In the present article research is presented aiming at reducing the tendency to rely on misinformation. After viewing a video clip, participants received a post-event narrative describing the events in the film which in the misled group included some incorrect information about the clip. They were then administered reinforced self-affirmation (RSA), a technique aiming at boosting self-confidence in order to increase the tendency to rely on own memory instead of external cues. This technique consists of self-affirmation by means of writing down one's greatest achievements in life and manipulated positive feedback. Feedback about memory, perception and independence of judgements was analyzed. All types of feedback effectively reduced the misinformation effect. Mediation analyzes confirmed that RSA operates via increased self-confidence or self-independence.

Project description:Among patients with chronic cardiopulmonary disease, increasing healthy behaviors improves outcomes, but such behavior changes are difficult for patients to make and sustain over time. This study aims to demonstrate how positive affect and self-affirmation improve health behaviors compared with a patient education control group. The patient education (PE control) patients completed a behavioral contract, promising to increase their physical activity or their medication adherence and received an educational guide. In addition to the contract and guide, the positive affect/self-affirmation intervention (PA intervention) patients also learned to use positive affect and self-affirmation to facilitate behavior change. Follow-up was identical. In 756 patients, enrolled in three randomized trials, the PA intervention resulted in increased positive affect and more success in behavior change than the PE control (p < .01). Behavior-specific self-efficacy also predicted success (p < .01). Induction of positive affect played a critical role in buffering against the adverse behavioral consequences of stress. Patients who experienced either negative psychosocial changes (p < .05) or interval negative life events (p < .05) fared better with the PA intervention than without it. The PA intervention increased self-efficacy and promoted success in behavior change by buffering stress.

Project description:Previous research found that health risk messages framed to be congruent with people's independent or interdependent self-construal were not consistently more effective than incongruent messages. We argue that people potentially process the self-construal congruent health risk messages in a biased manner. To test this proposition, we examined the role of self-affirmation, which is expected to reduce defensive processing, in college nonsmokers' responses to an antismoking message congruent vs. incongruent with their dominant self-construals. Results from an online experiment suggested that self-affirmation moderated the self-congruency effect. Specifically, among college nonsmokers endorsing a dominant interdependent self-construal, self-congruency effect emerged only when the group was engaged in self-affirmation. Among college nonsmokers endorsing a dominant independent self-construal, with no prior affirmation, the group reported self-incongruent messages better than the self-congruent messages. After being engaged in self-affirmation, the group reported similar effects for self-congruent and self-incongruent messages. Theoretical and practical implications of our findings are discussed.

Project description:Interrogative suggestibility, as measured with Gudjonsson Suggestibility Scales, consists of an individual's tendency to yield to misleading questions (Yield) and to change answers after negative feedback (Shift). This study aimed to determine whether reinforced self-affirmation (RSA), a technique that aims to boost self-confidence in order to increase the tendency to rely on one's own memory instead of external cues, can reduce interrogative suggestibility. RSA consists of self-affirmation induced by means of writing down one's greatest achievements in life and of manipulated positive feedback. The efficacy of two kinds of positive feedback was explored. Shift was reduced by positive feedback relating both to memory and to the feeling that a person is very independent in their judgements, while only feedback related to memory reduced Yield. The results are discussed in terms of the different mechanisms underlying Yield and Shift. Inducing independence of judgements might not have been effective in the case of Yield because to some extent it taps opinions but not the quality of a cognitive process such as memory. An individual may believe in their own opinions and views but still be unsure about the quality of their own memory.

Project description:Self-affirmation theory posits that people are motivated to maintain a positive self-view and that threats to perceived self-competence are met with resistance. When threatened, self-affirmations can restore self-competence by allowing individuals to reflect on sources of self-worth, such as core values. Many questions exist, however, about the underlying mechanisms associated with self-affirmation. We examined the neural mechanisms of self-affirmation with a task developed for use in a functional magnetic resonance imaging environment. Results of a region of interest analysis demonstrated that participants who were affirmed (compared with unaffirmed participants) showed increased activity in key regions of the brain's self-processing (medial prefrontal cortex?+?posterior cingulate cortex) and valuation (ventral striatum?+?ventral medial prefrontal cortex) systems when reflecting on future-oriented core values (compared with everyday activities). Furthermore, this neural activity went on to predict changes in sedentary behavior consistent with successful affirmation in response to a separate physical activity intervention. These results highlight neural processes associated with successful self-affirmation, and further suggest that key pathways may be amplified in conjunction with prospection.

Project description:Choice blindness is the failure to detect a discrepancy between a choice and its outcome. The misinformation effect occurs when the recollection of an event changes because new, misleading information about the event is received. The purpose of this study was to merge the choice blindness and misinformation effect paradigms, and thus examine whether choice blindness can be created for individuals' recollections of a witnessed event, and whether this will affect their later recollections of the event. Thus, as a way of delivering misinformation the participants ostensibly became their own source of the misleading information. The participants watched a short film and filled out a questionnaire about events shown in the film. Some of their answers were then manipulated using reattachable stickers, which allowed alteration of their original answers. The participants gave justifications for their manipulated choices, and later their recollection of the original event was tested through another questionnaire. Choice blindness was created for a majority of the participants. A majority of the choice blind participants later changed their reported recollection of the event in line with the manipulations, whereas only a small minority of the participants in the control condition changed their recollection. This study provides new information about the misinformation effect, suggesting that this effect also can occur when misinformation is given immediately following presentation of the original stimuli, and about choice blindness and its effects on the recollections of events. The results suggest that memory blindness can be created when people inadvertently supply themselves with misleading information about an event, causing a change in their recollection.

Project description:ObjectiveStress is a risk factor for numerous negative health outcomes, including cognitive impairment in late-life. The negative association between stress and cognition may be mediated by depressive symptoms, which separate studies have identified as both a consequence of perceived stress and a risk factor for cognitive decline. Pathways linking perceived stress, depressive symptoms, and cognition may be moderated by sociodemographics and psychosocial resources. The goal of this cross-sectional study was to identify modifying factors and enhance understanding of the mechanisms underlying the stress-cognition association in a racially and ethnically diverse sample of older adults.MethodA linear regression estimated the association between perceived stress and episodic memory in 578 older adults (Mage = 74.58) in the Washington Heights-Inwood Columbia Aging Project. Subsequent models tested whether depressive symptoms mediated the stress-memory relationship and whether sociodemographics (gender, race, and ethnicity) or perceived control moderated these pathways.ResultsIndependent of sociodemographics and chronic diseases, greater perceived stress was associated with worse episodic memory. This relationship was mediated by more depressive symptoms. Higher perceived control buffered the association between stress and depressive symptoms. There was no significant moderation by gender, race, or ethnicity.ConclusionDepressive symptoms may play a role in the negative association between perceived stress and cognition among older adults; however, longitudinal analyses and studies using experimental designs are needed. Perceived control is a modifiable psychological resource that may offset the negative impact of stress.

Project description:High levels of acute and chronic stress are known to impair problem-solving and creativity on a broad range of tasks. Despite this evidence, we know little about protective factors for mitigating the deleterious effects of stress on problem-solving. Building on previous research showing that self-affirmation can buffer stress, we tested whether an experimental manipulation of self-affirmation improves problem-solving performance in chronically stressed participants. Eighty undergraduates indicated their perceived chronic stress over the previous month and were randomly assigned to either a self-affirmation or control condition. They then completed 30 difficult remote associate problem-solving items under time pressure in front of an evaluator. Results showed that self-affirmation improved problem-solving performance in underperforming chronically stressed individuals. This research suggests a novel means for boosting problem-solving under stress and may have important implications for understanding how self-affirmation boosts academic achievement in school settings.

Project description:BackgroundAlthough self-regulation interventions are effective in promoting exercise behaviors, moderators and mediators of interventions among older adults are not well established. This study aimed to examine whether (1) self-regulation intervention promoted exercise behavior, (2) health literacy and habit strength moderated the intervention effect, and (3) self-regulation and habit strength mediated the intervention effect among older adults.MethodsThis study was a randomized, non-blinded, controlled crossover trial. The baseline questionnaire survey assessed the average amount of exercise time per day, self-regulation, habit strength, health literacy, and socio-demographic factors. After the baseline survey, 393 community-dwelling older adults were randomly assigned to either the immediate intervention or the delayed intervention group. For the immediate group, print-based materials were provided once a week for 7 weeks before a second questionnaire survey. For the delayed group, the materials were provided only after the second survey. Finally, a third survey was conducted for both groups.ResultsThe mixed models showed that the average exercise time was increased after the intervention in both groups. Multiple regression analyses revealed that no factor moderated the intervention effect. From the path analyses, the mediating effect of self-regulation on the relationship between intervention and changes in average exercise time was supported, but the mediating role of habit strength was not clearly indicated.ConclusionsAlthough the mediating roles of habit strength for the intervention effects are still inconclusive, self-regulation intervention can promote exercise behavior among older adults, regardless of their health literacy level, habit strength, and socio-demographic characteristics.

Project description:ImportanceStereotype threat, or the fear of confirming a negative stereotype about one's social group, may contribute to racial differences in adherence to medications by decreasing patient activation to manage chronic conditions.ObjectiveTo examine whether a values affirmation writing exercise improves medication adherence and whether the effect differs by patient race.Design, setting, and participantsThe Hypertension and Values trial, a patient-level, blinded randomized clinical trial, compared an intervention and a control writing exercise delivered immediately prior to a clinic appointment. Of 20 777 eligible, self-identified non-Hispanic Black and White patients with uncontrolled hypertension who were taking blood pressure (BP) medications, 3891 were approached and 960 enrolled. Block randomization by self-identified race ensured balanced randomization. Patients enrolled between February 1, 2017, and December 31, 2019, at 11 US safety-net and community primary care clinics, with outcomes assessed at 3 and 6 months. Analysis was performed on an intention-to-treat basis.InterventionsFrom a list of 11 values, intervention patients wrote about their most important values and control patients wrote about their least important values.Main outcomes and measuresThe primary outcome of adherence to BP medications was measured using pharmacy fill data (proportion of days covered >90%) at baseline, 3 months, and 6 months. The secondary outcome was systolic and diastolic BP. Patient activation to manage their health was also measured.ResultsOf 960 patients, 474 (286 women [60.3%]; 256 Black patients [54.0%]; mean [SD] age, 63.4 [11.9] years) were randomly assigned to the intervention group and 486 (288 women [59.3%]; 272 Black patients [56.0%]; mean [SD] age, 62.8 [12.0] years) to the control group. Baseline medication adherence was lower (318 of 482 [66.0%] vs 331 of 412 [80.3%]) and mean (SE) BP higher among Black patients compared with White patients (systolic BP, 140.6 [18.5] vs 137.3 [17.8] mm Hg; diastolic BP, 83.9 [12.6] vs 79.7 [11.3] mm Hg). Compared with baseline, pharmacy fill adherence did not differ between intervention and control groups at 3 months (odds ratio [OR], 0.91 [95% CI, 0.57-1.43]) or at 6 months (OR, 0.86 [95% CI, 0.53-1.38]). There were also no treatment effect differences in pharmacy fill adherence by patient race (Black patients at 3 months: OR, 1.08 [95% CI, 0.61-1.92]; at 6 months: OR, 1.04 [95% CI, 0.58-1.87]; White patients at 3 months: OR, 0.68 [95% CI, 0.33-1.44]; at 6 months: OR, 0.55 [95% CI, 0.24-1.27]). Immediately after the intervention, the median patient activation was higher in intervention patients than in control patients, but this difference was not statistically significant in an unadjusted comparison (75.0 [IQR, 65.5-84.8] vs 72.5 [IQR, 63.1-80.9]; P = .06). In adjusted models, the Patient Activation Measure score immediately after the intervention was significantly higher in the intervention patients than in control patients (mean difference, 2.3 [95% CI, 0.1-4.5]).Conclusions and relevanceA values affirmation intervention was associated with higher patient activation overall but did not improve adherence or blood pressure among Black and White patients with hypertension.Trial registrationClinicalTrials.gov Identifier: NCT03028597.
