“Orthotopic” ossiculum terminale persistens and atlantoaxial instability in a child less than 12 years of age: a case report and review of the literature

We report ossiculum terminale persistens associated with atlantoaxial instability in a child less than 12 years of age. Static and dynamic X-rays, thin-cut computed tomography with sagittal and coronal reconstructions, and magnetic resonance imaging of the cervical spine showed atlantoaxial instability and an “orthotopic” ossiculum terminale persistens. This pathologic state was differentiated from the primary ossification center at the tip of the odontoid, which normally is not expected to fuse with the body of the odontoid until the age of 12 years. The patient was taken to the operating room for a posterior instrumented fusion of C1 and C2. The patient has done well in short- and long-term follow-up

Individual differences in neural responses to social rejection: The joint effect of self-esteem and attentional control

Individuals with low self-esteem have been found to react more negatively to signs of interpersonal rejection than those with high self-esteem. However, previous research has found that individual differences in attentional control can attenuate negative reactions to social rejection among vulnerable, low self-esteem individuals. The current fMRI study sought to elucidate the neurobiological substrate of this buffering effect. We hypothesized and found that while looking at scenes of social rejection (vs negative scenes) low self-esteem high attentional control individuals engaged the rostral anterior cingulate cortex (rACC), an area of the brain associated with emotional control, more than their low self-esteem low attentional control peers. Furthermore, we found that low self-esteem high attentional control individuals evaluated social rejection as less arousing and less rejecting in a separate behavioral task. Importantly, activation in the rACC fully mediated the relationship between the interaction of self-esteem and attentional control and emotional evaluations, suggesting that the rACC activation underlies the buffering effects of attentional control. Results are discussed in terms of individual differences in emotional vulnerability and protection and by highlighting the role of rACC in emotion regulation

Blind and Deaf to Acceptance: The Role of Self-Esteem in Capitalizing on Social Acceptance

Across two studies, we evaluated whether people with low self-esteem are less likely to capitalize on, or take full advantage of, their romantic partners' accepting behaviors. We conceptualized capitalization as the tendency to perceive acceptance when it occurs, and to experience positive changes in affect and relationship satisfaction when acceptance is perceived. We found that participants with low self-esteem under-perceived their partners' acceptance, both in daily life and in the laboratory. When these behaviors were noticed, participants with low self-esteem experienced smaller, and temporally shorter, boosts in positive affect and relationship satisfaction than participants with high self-esteem. Moreover, the degree to which participants noticed social acceptance in daily life predicted relationship closeness over time. These results generally supported our predictions, and suggest that targeting responses to social acceptance may be an important point of intervention for future studies evaluating ways to improve self-esteem

Cohabiting Couples Coping during the COVID-19 Pandemic

This project examines changes in relationship quality among cohabiting couples during and after the COVID-19 pandemic and the effect of stress on relationship quality. The goals of the project are to identify key factors that predict both positive and negative changes in relationship quality, as well investigate the ways in which concurrent stress (both partners experiencing stress) uniquely affects relationship and individual outcomes. There are two versions of this study: Version 1 is a 6-month 4-wave longitudinal study tracking individuals who were sheltering in place with their romantic partners during the COVID-19 pandemic. We will also collect data from a subset of their partners. Version 2 includes the same questions as Version 1 but is a cross-sectional study conducted via social media (participants are required to be cohabiting with a romantic partner, but not sheltering-in-place together). We will also collect data from a subset of their partners

Child inhibited temperament and caregiver distraction encouragement jointly predict children’s delay of gratification competencies

A cool attentional focus during the classic delay of gratification (DG) task involves shifting attention away from the emotion-arousing features and is a key mechanism that underlies children's ability to resist temptation and wait. Yet, we know relatively little about what gives rise to individual differences in cool focus in the first place. The current study (N = 162, Mage = 6.86 years) addressed this question by focusing on key aspects of child temperament (i.e., behavioral inhibition, BI) and caregiver emotion socialization (i.e., distraction encouragement) as joint predictors of cool focus. We theorized that because children are left alone in an unfamiliar environment for an undefined duration, the DG task would be especially taxing for children higher in BI, hindering their ability to deploy a cool focus and wait. We also reasoned that caregiver encouragement of distraction would serve as a protective factor by allowing children higher in BI to more easily activate a cool focus even when experiencing a taxing task. Results were partially consistent with these hypotheses, shedding new light on precursors to a central ingredient of DG ability

Predictors of relationship satisfaction during the COVID-19 pandemic

Prior work and theory suggest many vulnerabilities, stressors, and adaptive processes shape relationship satisfaction. In the current research, we used machine learning to understand which constructs have greater predictive importance for perceived changes in satisfaction since the pandemic began and satisfaction over the prior week. In a large sample collected at the beginning of the pandemic (N = 1873; Study 1), relationship processes were most predictive, explaining up to 70% of variance in satisfaction. Feeling appreciative of one's partner and being satisfied with quality time spent with one's partner were consistently top predictors of satisfaction. We also examined whether these important predictors were associated with changes in relationship satisfaction across the first year of the pandemic in a longitudinal subsample (N = 618; Study 2). Appreciation and satisfaction with quality time were associated with high and relatively stable relationship satisfaction over time
