RESUMEN

The biopsychosocial model of challenge and threat (BPS-CT) is a powerful framework linking psychological processes to reliable patterns of cardiovascular responses during motivated performance situations. Specifically, the BPS-CT poses challenge and threat as two motivational states that can emerge in response to a demanding, self-relevant task, where greater challenge arises when perceived resources are higher than demands, and greater threat arises when perceived resources are lower than demands. By identifying unique patterns of physiological responses associated with challenge and threat, respectively, the BPS-CT affords insight into subjective appraisals of resources and demands, and their determinants, during motivated performance situations. Despite its broad utility, lack of familiarity with physiological concepts and difficulty with identifying clear guidelines in the literature are barriers to wider uptake of this approach by behavioral researchers. Our goal is to remove these barriers by providing a comprehensive, step-by-step tutorial on conducting an experiment using the challenge and threat model, offering concrete recommendations for those who are new to the method, and serving as a centralized collection of resources for those looking to deepen their understanding. The tutorial spans five parts, covering theoretical introduction, lab setup, data collection, data analysis, and appendices offering additional details about data analysis and equipment. With this, we aim to make challenge and threat research, and the insights it offers, more accessible to researchers throughout the behavioral sciences.

RESUMEN

OBJECTIVE: Work on longevity has found protective social, cognitive, and emotional factors, but to date we have little understanding of the impact of motivational dynamics. Autonomy orientation, or stable patterns of self-regulation, is theorized to be a protective factor for long-term mental and physical health (Ryan & Deci, 2017), and it is therefore a prime candidate for examining how stable psychosocial factors are linked to longevity, or life expectancy. METHOD: Essays written in the 1930s by participants in the Nun Study were coded for indicators of an autonomy orientation. These were selected in line with an extensive theoretical literature based in self-determination theory (Deci & Ryan, 1985). Essays were coded for the propensity for choice in action, susceptibility to pressure, self-reflection, integration of experiences, and parental support for autonomy. These coded variables were used to predict age of death. RESULTS: Using 176 codable essays provided by now-deceased participants, linear regression analyses revealed that choiceful behavior, self-reflection, and parent autonomy support predicted age of death. Participants who demonstrated these stable and beneficial motivational characteristics lived longer. CONCLUSIONS: Personality constructs reflecting a healthy form of self-regulation are associated with long-term health. Implications for health interventions are discussed.

RESUMEN

Important others' perceptions influence self-perceptions. This presents a challenge for the critical developmental task of integrating all aspects of identity, as identities that are devalued or stigmatized by society are harder to own than valued ones. Across 3 studies, we tested the idea that conflictual or stigmatized identities are harder to own, or integrate into the self, than are nonconflictual ones, and we examine how receiving autonomy support for an identity-support for authentic identity exploration and expression-can facilitate ownership of that identity. Cross-sectional (n = 543), experience-sampling (n = 66), and experimental methods (n = 209) tested the dynamics of autonomy-supportive others on identity ownership. Data from these studies converge to show that conflictual identities are indeed harder to own than nonconflictual ones, but that autonomy support predicts greater ownership and psychological health, especially for conflictual identities. In the final study, we replicate these dynamics in 3 identities stigmatized by society: sexual minority, ethnic minority, and gender minority identities. Findings reveal the importance of integrating all aspects of identity-particularly those that are conflictual or stigmatized-into one's self-concept. We consider implications for counseling and clinical practice, as well as broadly for the psychological health of stigmatized individuals. (PsycINFO Database Record

RESUMEN

Academic life is full of learning, excitement, and discovery. However, academics also experience professional challenges at various points in their career, including repeated rejection, impostor syndrome, and burnout. These negative experiences are rarely talked about publicly, creating a sense of loneliness and isolation for people who presume they are the only ones affected by such setbacks. However, nearly everyone has these experiences at one time or another; therefore, talking about them should be a normal part of academic life. The goal of this article is to explore and destigmatize the common experiences of rejection, impostor syndrome, and burnout by sharing a collection of short personal stories from scholars at various stages of their careers with various types of academic positions. Josh Ackerman, Kate Sweeny, and Ludwin Molina discuss how they have dealt with repeated rejection. Linda Tropp, Nick Rule, and Brooke Vick share experiences with impostor syndrome. Finally, Bertram Gawronski, Lisa Jaremka, Molly Metz, and Will Ryan discuss how they have experienced burnout.

RESUMEN

MEAP, the moving ensemble analysis pipeline, is a new open-source tool designed to perform multisubject preprocessing and analysis of cardiovascular data, including electrocardiogram (ECG), impedance cardiogram (ICG), and continuous blood pressure (BP). In addition to traditional ensemble averaging, MEAP implements a moving ensemble averaging method that allows for the continuous estimation of indices related to cardiovascular state, including cardiac output, preejection period, heart rate variability, and total peripheral resistance, among others. Here, we define the moving ensemble technique mathematically, highlighting its differences from fixed-window ensemble averaging. We describe MEAP's interface and features for signal processing, artifact correction, and cardiovascular-based fMRI analysis. We demonstrate the accuracy of MEAP's novel B point detection algorithm on a large collection of hand-labeled ICG waveforms. As a proof of concept, two subjects completed a series of four physical and cognitive tasks (cold pressor, Valsalva maneuver, video game, random dot kinetogram) on 3 separate days while ECG, ICG, and BP were recorded. Critically, the moving ensemble method reliably captures the rapid cyclical cardiovascular changes related to the baroreflex during the Valsalva maneuver and the classic cold pressor response. Cardiovascular measures were seen to vary considerably within repetitions of the same cognitive task for each individual, suggesting that a carefully designed paradigm could be used to capture fast-acting event-related changes in cardiovascular state.

RESUMEN

While simultaneous acquisition of electrocardiography (ECG) data during MRI is a widely used clinical technique, the effects of the MRI environment on impedance cardiography (ICG) data have not been characterized. We collected echo planar MRI scans while simultaneously recording ECG and thoracic impedance using carbon fiber electrodes and customized amplifiers. Here, we show that the key changes in impedance (dZ/dt) and features of the ECG waveforms are not obstructed during MRI. We present a method for ensemble averaging ICG/ECG signals collected during MRI and show that it performs comparably with signals collected outside the MRI environment. These results indicate that ICG can be used during MRI to measure stroke volume, cardiac output, preejection period, and left ventricular ejection time.

RESUMEN

When individuals grow up with autonomy-thwarting parents, they may be prevented from exploring internally endorsed values and identities and as a result shut out aspects of the self perceived to be unacceptable. Given the stigmatization of homosexuality, individuals perceiving low autonomy support from parents may be especially motivated to conceal same-sex sexual attraction, leading to defensive processes such as reaction formation. Four studies tested a model wherein perceived parental autonomy support is associated with lower discrepancies between self-reported sexual orientation and implicit sexual orientation (assessed with a reaction time task). These indices interacted to predict anti-gay responding indicative of reaction formation. Studies 2-4 showed that an implicit/explicit discrepancy was particularly pronounced in participants who experienced their fathers as both low in autonomy support and homophobic, though results were inconsistent for mothers. Findings of Study 3 suggested contingent self-esteem as a link between parenting styles and discrepancies in sexual orientation measures.
