The ease-of-processing heuristic and the stability bias: dissociating memory, memory beliefs, and memory judgments

Judgments about memory are essential in promoting knowledge; they help identify trustworthy memories and predict what information will be retained in the future. In the three experiments reported here, we investigated the mechanisms underlying predictions about memory. In Experiments 1 and 2, single words were presented once or multiple times, in large or small type. There was a double dissociation between actual memory and predicted memory: Type size affected predicted but not actual memory, and future study opportunities affected actual memory but scarcely affected predicted memory. The results of Experiment 3 suggest that beliefs and judgments are largely independent, and neither consistently resembles actual memory. Participants' underestimation of future learning-a stability bias-stemmed from an overreliance on their current memory state in making predictions about future memory states. The overreliance on type size highlights the fundamental importance of the ease-of-processing heuristic: Information that is easy to process is judged to have been learned well.     

Us versus them: social identity shapes neural responses to intergroup competition and harm

Intergroup competition makes social identity salient, which in turn affects how people respond to competitors' hardships. The failures of an in-group member are painful, whereas those of a rival out-group member may give pleasure-a feeling that may motivate harming rivals. The present study examined whether valuation-related neural responses to rival groups' failures correlate with likelihood of harming individuals associated with those rivals. Avid fans of the Red Sox and Yankees teams viewed baseball plays while undergoing functional magnetic resonance imaging. Subjectively negative outcomes (failure of the favored team or success of the rival team) activated anterior cingulate cortex and insula, whereas positive outcomes (success of the favored team or failure of the rival team, even against a third team) activated ventral striatum. The ventral striatum effect, associated with subjective pleasure, also correlated with self-reported likelihood of aggressing against a fan of the rival team (controlling for general aggression). Outcomes of social group competition can directly affect primary reward-processing neural systems, which has implications for intergroup harm.     

Respecting the LDS/Mormon Minority on Campus: College Students’ Attitudes Toward Latter‐Day Saints

Members of the Church of Jesus Christ of Latter‐Day Saints remain a minoritized and marginalized population in the United States at large, a pattern mirrored on the majority of college and university campuses across the United States. This study addresses how social identities, institutional contexts, and intergroup dynamics within the postsecondary education environment contribute to cultivating college students’ attitudes toward LDS/Mormons and Mormonism. Using data collected from 13,584 college students attending 52 institutions across the country, the study employs multilevel modeling to examine these relationships. The analyses highlight the importance of productive interreligious contact in a supportive institutional context for shaping out‐group attitudes. Affirming the interplay between social identity and intergroup contact, effects on out‐group attitudes vary to some extent by religion/worldview. Implications for research and practice are discussed.     

States of Spiritual Awareness by Time,Activity, and Social Interaction

We explore how people experience the sacred in their everyday lives using a recently developed research technique—smartphone‐based experience sampling method (S‐ESM). The primary goal of our experience‐driven approach is to explore the contours and variations of spiritual awareness within people's day‐to‐day lives. We seek to better understand when and where spiritual awareness is likely to arise, and the contexts in which it is rare. Our smartphone‐based data allow us to track the many contexts in which an awareness of the sacred occurs, as reported in real time during people's normal daily activities. We parse out how immediate contextual factors and how people's more habitual behaviors are related to their spiritual experiences. This illuminates a wide range of factors that influence spiritual experiences that have not received much scholarly attention, and enables us to connect cutting‐edge quantitative methods with qualitative scholarship on spirituality. We hope this will open the door to the development of new theories of situated spiritual experience.     

Religion,Altruism, and Helping Strangers: A Multilevel Analysis of 126 Countries

This article tests how religion relates to helping strangers, an important but rarely studied measure of social solidarity and informal social capital. It uses the Gallup World Poll, a survey with nationally representative samples of 179,961 respondents from 126 countries. It finds that religious people, members of minority religions, and people in religiously diverse countries were more likely to help a stranger. Individuals living in devout countries were more likely to help strangers even if they themselves were not religious. The results suggest that religion plays a particularly important role in promoting the prosocial norms and values that motivate helping strangers.     

Comparing fixed‐amount and progressive‐amount DRO Schedules for tic suppression in youth with chronic tic disorders

Chronic tic disorders (CTDs) involve motor and/or vocal tics that often cause substantial distress and impairment. Differential reinforcement of other behavior (DRO) schedules of reinforcement produce robust, but incomplete, reductions in tic frequency in youth with CTDs; however, a more robust reduction may be needed to affect durable clinical change. Standard, fixed‐amount DRO schedules have not commonly yielded such reductions, so we evaluated a novel, progressive‐amount DRO schedule, based on its ability to facilitate sustained abstinence from functionally similar behaviors. Five youth with CTDs were exposed to periods of baseline, fixed‐amount DRO (DRO‐F), and progressive‐amount DRO (DRO‐P). Both DRO schedules produced decreases in tic rate and increases in intertic interval duration, but no systematic differences were seen between the two schedules on any dimension of tic occurrence. The DRO‐F schedule was generally preferred to the DRO‐P schedule. Possible procedural improvements and other future directions are discussed.     

Examination of MMPI–2–RF Substantive Scales as Indicators of Acute Suicidal Affective Disturbance Components

A new suicide-specific diagnostic entity, acute suicidal affective disturbance (ASAD), was recently proposed to fill a void in the nomenclature. Although several studies have examined the reliability, validity, and potential clinical utility of ASAD, no studies have examined personality indicators of ASAD. This study sought to examine the association between personality and psychopathology factors, as assessed by the Minnesota Multiphasic Personality Inventory–2–Revised Form (MMPI–2–RF), and constructs that comprise ASAD in a sample of 554 psychiatric outpatients who completed all measures prior to their intake appointments. A smaller subset of patients (N = 58) also completed a measure designed to assess lifetime ASAD symptoms. Results indicated that ASAD symptoms were associated with traits characterized by emotional turmoil and atypical cognitive processes. Further, suicide-related criteria that comprise ASAD were related to low positive emotionality and hopelessness, whereas the overarousal criteria were associated with somatic symptoms and an inability to tolerate frustration and stress. These findings expand on previous research that examines the convergent and discriminant validity of ASAD and could inform clinical treatment by providing insight into personality traits that might be associated with acute suicide risk.     

Bipedal Hopping Reveals Evidence of Advanced Neuromuscular Aging Among People With Mild Multiple Sclerosis

Measures of walking such as the timed 25-ft walk test (T25FWT) may not be able to detect subtle impairment in lower limb function among people with multiple sclerosis (MS). We examined bipedal hopping to determine to what extent people with mild (Expanded Disease Severity Scale ≤ 3.5) MS (n = 13) would differ compared to age-, gender-, and education-matched controls (n = 9) and elderly participants (n = 13; ≥ 70 years old). We estimated lower limb power (e.g., hop length, velocity), consistency (e.g., variability of hop length, time), and symmetry (ratio of left to right foot). Participants completed the T25FWT and, after a rest, they then hopped using both feet 4 times along the walkway. We found that although all groups scored below the 6 -s cutoff for T25FWT, the elderly group had significantly shorter hop lengths, more variability, and more asymmetry than the controls. The results of the MS group were not significantly different from the elderly or controls in most measures and most of their values fell between the control and elderly groups. Hop length, but not measures of walking predicted Expanded Disease Severity Scale score (R² = .38, p = .02). Bipedal hopping is a potentially useful measure of lower limb neuromuscular performance.     

Replacing the Moral Foundations: An Evolutionary‐Coalitional Theory of Liberal‐Conservative Differences

Moral Foundations Theory (MFT) explains liberal‐conservative differences as arising from different moral intuitions, with liberals endorsing “individualizing” foundations (Harm and Fairness) and conservatives also endorsing “binding” foundations (Authority, Respect, and Purity). We argue these labels misconstrue ideological differences and propose Evolutionary‐Coalitional Theory (ECT) as an alternative, explaining how competitive dynamics in the ancestral social environment could produce the observed ideological differences. We test ECT against MFT across three studies. Study 1 shows the so‐called “binding” orientation entails the threat‐sensitivity and outgroup antagonism predicted by ECT; that is, an authoritarian motive. Similarly, Study 2 shows the so‐called “individualizing” orientation is better described as a universalizing motive, one reflecting a broader set of moral commitments (e.g., to nature) and a broader sociality than the egocentrism implied by MFT. Study 3 provides a factor analysis reducing “binding” to authoritarianism and “individualizing” to universalism, with the latter loading against social dominance orientation (SDO). A hierarchical regression then provides additional evidence for ECT, showing this dominating motive (SDO) accounts for variance in conservatism that MFT leaves unexplained. Collectively, these three studies suggest that ECT offers a more accurate and precise explanation of the key psychological differences between liberals and conservatives.     

Determinants of depressive mood states in everyday life: An experience sampling study

This study tests relative contributions and time-course of proposed risk/protective factors (e.g., stress, coping, and lack of social interactions) for influencing depressed mood states in daily life. Seventy-three participants completed baseline measurement of major depressive disorder symptomatology, followed by smartphone app-based monitoring of momentary experiences of depressed mood and risk/protective factors for 7 days. All predictors had deteriorating impacts on mood as lag increased, and the optimal lag appears to be less than 120 min. Linear decay in effect sizes was found for physical activity, social interaction, and tiredness, whereas exponential decline in effect sizes was found for stress and coping ability. Stress, coping, and depressed mood at the prior time-point were the best predictors of subsequent mood. These effects did not differ as a function of trait depressive symptom severity. Findings highlight the influence of spacing of assessments in identification and magnitude of predictors of mood states, and provide insights into key drivers of change in mood and their time-course.
