Decisions Under Distress: Stress Profiles Influence Anchoring and Adjustment

ABSTRACT— People frequently make decisions under stress. Understanding how stress affects decision making is complicated by the fact that not all stress responses are created equal. Challenge states, for example, occur when individuals appraise a stressful situation as demanding, but believe they have the personal resources to cope, and are characterized by efficient cardiovascular reactivity and approach motivation. Threat states, in contrast, occur when situational demands are perceived to outweigh resources and are characterized by less efficient cardiovascular reactivity and withdrawal motivation. We randomly assigned participants to social-feedback conditions (i.e., positive or negative feedback) designed to engender challenge or threat, or a no-stress condition. Participants then completed an anchoring-and-adjustment questionnaire. Those assigned to the challenge condition adjusted more from self-generated anchors than those assigned to the threat condition. Cardiovascular responses mediated the relationship between condition and adjustment. This study demonstrates the importance of considering profiles of cardiovascular reactivity when examining the influence of stress on decision making.     

Problem-solving training for family caregivers of women with disabilities: A randomized clinical trial

ObjectiveTo examine the effectiveness of an individualized problem-solving intervention provided to family caregivers of women living with severe disabilities.DesignFamily caregivers were randomly assigned to an education-only control group or a problem-solving training (PST) intervention group. Participants received monthly contacts for 1 year.ParticipantsFamily caregivers (64 women, 17 men) and their care recipients (81 women with various disabilities) consented to participate.Main outcome measuresCaregivers completed the Social Problem-Solving Inventory – Revised, the Center for Epidemiological Studies Depression scale, the Satisfaction with Life scale, and a measure of health complaints at baseline and in three additional assessments throughout the year.ResultsMultilevel modeling was used to conduct intent-to-treat analyses of change trajectories for each outcome variable. Caregivers who received PST reported a significant linear decrease in depression over time; no effects were observed for caregiver health or life satisfaction. Caregivers who received PST also displayed an increase in constructive problem-solving styles over the year.ConclusionsPST may benefit community-residing family caregivers of women with disabilities, and it may be effectively provided in home-based sessions that include face-to-face visits and telephone sessions.     

Threatened by the unexpected: physiological responses during social interactions with expectancy-violating partners

Individuals who violate expectations increase uncertainty during social interactions. Three experiments explored whether expectancy-violating partners engender "threat" responses in perceivers. Participants interacted with confederates who violated or confirmed expectations while multiple measures were assessed, including cardiovascular reactivity, task performance, appraisals, and behavior. In Experiments 1 and 2, participants interacted with White or Latino confederates who described their family backgrounds as either high or low socioeconomic status. In Experiment 3, participants interacted with Asian or White confederates who spoke with expected accents or southern accents. Participants interacting with expectancy-violating partners (e.g., Asians with southern accents) exhibited cardiovascular responses consistent with threat, poorer task performance, and manifested negative and defeat-related behavior. Implications for decreasing prejudicial responses via uncertainty reduction are discussed.     

Dimensions in appreciation of car interior design

We report two studies in which the interplay between stimulus properties and perceiver characteristics in the appreciation car interiors was investigated. In Experiment 1 three design components, complexity, curvature and innovativeness, which are all thought to affect design appreciation were combined in a fully factorial design. All dimensions were confirmed to affect ratings, and curvature and innovativeness particularly affected the attractiveness ratings. Curved and non‐innovative designs were generally preferred. Moreover, participants who were particularly interested in art were more sensitive to curvature and innovativeness. In Experiment 2 two dimensions of Experiment 1 were replicated using similar stimuli. Moreover, the specific effects of a design knowledge treatment were investigated. Results replicated the preference for curved and non‐innovative (rather classic) designs. The treatment had only small effects, which support a general rather than dimension‐specific effects of cognitive pre‐information. Copyright © 2005 John Wiley & Sons, Ltd.     

An alternative approach to relapse analysis: Using Monte Carlo methods and proportional rates of response

Relapse is the recovery of a previously suppressed response. Animal models have been useful in examining the mechanisms underlying relapse (e.g., reinstatement, renewal, reacquisition, resurgence). However, there are several challenges to analyzing relapse data using traditional approaches. For example, null hypothesis significance testing is commonly used to determine whether relapse has occurred. However, this method requires several a priori assumptions about the data, as well as a large sample size for between‐subjects comparisons or repeated testing for within‐subjects comparisons. Monte Carlo methods may represent an improved analytic technique, because these methods require no prior assumptions, permit smaller sample sizes, and can be tailored to account for all of the data from an experiment instead of some limited set. In the present study, we conducted reanalyses of three studies of relapse (Berry, Sweeney, & Odum, 2014 ; Galizio et al., 2018 ; Odum & Shahan, 2004 ) using Monte Carlo techniques to determine if relapse occurred and if there were differences in rate of response based on relevant independent variables (such as group membership or schedule of reinforcement). These reanalyses supported the previous findings. Finally, we provide general recommendations for using Monte Carlo methods in studies of relapse.     

Associations between childhood adversity and daily suppression and avoidance in response to stress in adulthood: can neurobiological sensitivity help explain this relationship?

Background and objectives: Although it has been postulated that psychological responses to stress in adulthood are grounded in childhood experiences in the family environment, evidence has been inconsistent. This study tested whether two putative measures of neurobiological sensitivity (vagal flexibility and attentional capacity) moderated the relation between women’s reported exposure to a risky childhood environment and current engagement in suppressive or avoidant coping in response to daily stress.

Design and methods: Adult women (N?=?158) recruited for a study of stress, coping, and aging reported on early adversity (EA) in their childhood family environment and completed a week-long daily diary in which they described their most stressful event of the day and indicated the degree to which they used suppression or avoidance in response to that event. In addition, women completed a visual tracking task during which heart rate variability and attentional capacity were assessed.

Results: Multilevel mixed modeling analyses revealed that greater EA predicted greater suppression and avoidance only among women with higher attentional capacity. Similarly, greater EA predicted greater use of suppression, but only among women with greater vagal flexibility.

Conclusion: Childhood adversity may predispose individuals with high neurobiological sensitivity to a lifetime of maladaptive coping.     

Problem-solving training via videoconferencing for family caregivers of persons with spinal cord injuries: a randomized controlled trial

Objective

To examine the effectiveness of an individualized problem-solving intervention delivered in videoconferencing sessions with family caregivers of persons living with a spinal cord injury (SCI) and possible contagion effects on care recipients.

Design

Family caregivers were randomly assigned to an education-only control group or an intervention group in which participants received problem-solving training (PST) in monthly videoconference session for a year.

Participants

Sixty-one caregivers (54 women, 7 men) and their care recipients (40 men, 21 women) consented to participate.

Main outcome measures

The Social Problem-Solving Inventory-Revised was administered to caregivers. Caregivers and care recipients completed the Inventory to Diagnose Depression, the SF-36 and the Satisfaction with Life scale at pre-treatment, 6 months and 12 months.

Results

Twenty-eight caregivers discontinued the study and their follow-up data were unavailable at the final assessment. Older caregivers were more likely than younger caregivers to remain in the study. Intent-to-treat analyses projected a significant decrease in depression among caregivers receiving PST; efficacy analyses indicated this effect was pronounced at the 6th month assessment. ITT analyses and efficacy analyses revealed that care recipients of caregivers receiving PST reported gains in social functioning over time.

Conclusions

Community-based, telehealth interventions may benefit family caregivers and their care recipients, but the mechanisms of these effects are unclear. Attrition and sample issues should be considered in future studies with these populations.     

The efficacy of cognitive-behavioral interventions for reducing anxiety sensitivity: a meta-analytic review

The present study meta-analytically reviewed the efficacy of cognitive-behavioral therapy (CBT) vs. control conditions in the reduction of anxiety sensitivity. A computerized search was conducted to indentify CBT outcome studies that included the Anxiety Sensitivity Index as a dependent variable. Of the 989 studies that were identified, 24 randomized-controlled trials with a total of 1851 participants met inclusion criteria and were included in the analysis. Data were extracted separately for treatment-seeking (16 studies) and at-risk (eight studies) samples. Results indicated large effect sizes for treatment-seeking samples, Hedges' g=1.40, SE=0.21, 95% CI: 1.00-1.81, p<0.001, and moderate to large effect sizes for at risk samples Hedges' g=0.74, SE=0.18, 95% CI: 0.39-1.08, p<0.001. Additionally, both the amount of therapist contact and control modality (waitlist vs. psychological control) moderated the effect sizes for treatment-seeking samples. Our review indicates that CBT is efficacious in reducing anxiety sensitivity. However, more research is needed to determine the mechanisms by which CBT exert its effects on anxiety sensitivity.

The dark side of creativity: biological vulnerability and negative emotions lead to greater artistic creativity

Historical and empirical data have linked artistic creativity to depression and other affective disorders. This study examined how vulnerability to experiencing negative affect, measured with biological products, and intense negative emotions influenced artistic creativity. The authors assessed participants' baseline levels of an adrenal steroid (dehydroepiandrosterone-sulfate, or DHEAS), previously linked to depression, as a measure of affective vulnerability. They then manipulated emotional responses by randomly assigning participants to receive social rejection or social approval or to a nonsocial situation. Participants then completed artistic collages, which were later evaluated by artists. Results confirmed a person-by-situation interaction. Social rejection was associated with greater artistic creativity; however, the interaction between affective vulnerability (lower baseline DHEAS) and condition was significant, suggesting that situational triggers of negative affect were especially influential among those lower in DHEAS, which resulted in the most creative products. These data provide evidence of possible biological and social pathways to artistic creativity.
