Perceiving greater commitment increases selfishness among disagreeable people.

Perceiving that a partner is highly committed tends to benefit close relationships. However, there may be relational drawbacks to perceiving high commitment. In particular, given that high commitment may signal that a partner is unlikely to leave the relationship, perceiving that a partner is highly committed might lead people low in agreeableness to feel comfortable behaving more selfishly toward that partner. One correlational study consisting of a highly diverse sample of individuals (n = 307), one observational study of newlywed couples (n = 202), and one experiment with undergraduate couples (n = 252) examined whether the implications of perceived partner commitment for selfish behaviors depend on agreeableness. Results demonstrated that perceiving high commitment resulted in more selfish behavior among disagreeable participants (Studies 1-3), but less selfish behavior among agreeable participants (Studies 1 and 3). Together, these results suggest that signaling commitment to disagreeable partners may backfire in romantic relationships.

Shift schedule effects on firefighter health and fitness.

BACKGROUND: Firefighter health is of utmost importance both to first responders and the individuals they serve daily. The impact of shift schedule on firefighter health remains poorly understood. OBJECTIVE: The purpose of this study was to examine differences in health and performance outcomes in firefighters across two different shift schedules. METHODS: Firefighter (N = 1995) body composition, muscular strength, endurance, flexibility, and cardiorespiratory endurance were assessed and described. A Mann-Whitney U test was conducted to compare differences between shift schedules (48/96 and 4's and 6's). RESULTS: There was a statistically significant difference in BMI (U = 70115, z=-1.988, p = .047), BF% (U = 67341, z=-2.779, p = .005), and trunk flexion score (U = 81362, z = 1.979, p = .048) favoring the 48/96 shift schedule. CONCLUSION: Firefighters following a 48/96 shift schedule exhibited improved body composition and fitness performance in comparison to peers who followed a 4's and 6's shift schedule. Findings may guide regional firefighter scheduling to optimize health and performance.

Symmetric expression of ohnologs encoding conserved antiviral responses in tetraploid common carp suggest absence of subgenome dominance after whole genome duplication.

Allopolyploids often experience subgenome dominance, with one subgenome showing higher levels of gene expression and greater gene retention. Here, we address the functionality of both subgenomes of allotetraploid common carp (Cyprinus carpio) by analysing a functional network of interferon-stimulated genes (ISGs) crucial in anti-viral immune defence. As an indicator of subgenome dominance we investigated retainment of a core set of ohnologous ISGs. To facilitate our functional genomic analysis a high quality genome was assembled (WagV4.0). Transcriptome data from an in vitro experiment mimicking a viral infection was used to infer ISG expression. Transcriptome analysis confirmed induction of 88 ISG ohnologs on both subgenomes. In both control and infected states, average expression of ISG ohnologs was comparable between the two subgenomes. Also, the highest expressing and most inducible gene copies of an ohnolog pair could be derived from either subgenome. We found no strong evidence of subgenome dominance for common carp.

Prevalence of chronic and multisite pain in adolescents and young adults with ADHD: a comparative study between clinical and general population samples (the HUNT study).

Attention-deficit/hyperactivity disorder (ADHD) and chronic pain are prevalent and associated. We examined the prevalence and distribution of chronic pain in adolescents and young adults with ADHD using 9-years longitudinal data (from T1:2009-2011 to T3:2018-2019) with three time points from a clinical health survey compared to two age-matched reference population-based samples. Mixed-effect logistic regression and binary linear regression were used to estimate the probability for chronic and multisite pain at each time point and to compare the prevalence of chronic pain with the reference populations. The prevalence of chronic and multisite pain was high in those with ADHD, especially in female young adults, with highly prevalent chronic pain at 9 years of follow-up (75.9%) compared to 45.7% in females in the reference population. The probability of having pain was only statistically significant for chronic pain in males at 3 years of follow-up (41.9%, p = 0.021). Those with ADHD were at higher risk of reporting single-site and multisite pain compared to the general population at all measurement points. Longitudinal studies should be tailored to further understand the complex sex differences of comorbid chronic pain and ADHD in adolescents, exploring predictive factors of pain assessing long-term associations with bodyweight, psychiatric comorbidities, and possible mechanisms of stimulant use effects on pain.

Examining the social in the prosocial: Episode-level features of social interactions and kind acts predict social connection and well-being.

Experiments prompting people to engage in more prosocial behavior (e.g., acts of kindness) or simple social interactions (e.g., acting extraverted) have both shown promise in boosting well-being. However, little is known about how much the impact on well-being depends on the type of interpersonal interaction (i.e., social vs. prosocial) or on other proximal features (e.g., whether the interaction takes place online vs. in-person, the closeness of the relationship, or amount of social connection associated with a given interaction). We randomly assigned a sample of full-time employees recruited via a special employed mTurk sample (N = 754) to perform weekly acts of kindness online versus in-person, to engage in weekly social interactions online versus in-person, or to list their daily activities (control) over the course of 4 weeks. First, on average, all conditions reported improvements in well-being (i.e., increases in positive affect and life satisfaction, decreases in negative affect) across the 4-week intervention period. Second, relative to controls, the four experimental groups reported increases in general social connectedness over time. Finally, according to auxiliary analyses collapsed across the experimental condition, closer relationship with target and non-digital medium of delivery predicted episode-level social connection, which, in turn, was associated with general social connectedness and positive affect. We conclude that the "who" and the "how" of a behavior (i.e., its target, its delivery method, and the feelings of social connection generated) are important for well-being, but not the "what" (i.e., whether the behavior is social or prosocial).

Artificial intelligence-based radiomics on computed tomography of lumbar spine in subjects with fragility vertebral fractures.

PURPOSE: There is emerging evidence that radiomics analyses can improve detection of skeletal fragility. In this cross-sectional study, we evaluated radiomics features (RFs) on computed tomography (CT) images of the lumbar spine in subjects with or without fragility vertebral fractures (VFs). METHODS: Two-hundred-forty consecutive individuals (mean age 60.4 ± 15.4, 130 males) were evaluated by radiomics analyses on opportunistic lumbar spine CT. VFs were diagnosed in 58 subjects by morphometric approach on CT or XR-ray spine (D4-L4) images. DXA measurement of bone mineral density (BMD) was performed on 17 subjects with VFs. RESULTS: Twenty RFs were used to develop the machine learning model reaching 0.839 and 0.789 of AUROC in the train and test datasets, respectively. After correction for age, VFs were significantly associated with RFs obtained from non-fractured vertebrae indicating altered trabecular microarchitecture, such as low-gray level zone emphasis (LGLZE) [odds ratio (OR) 1.675, 95% confidence interval (CI) 1.215-2.310], gray level non-uniformity (GLN) (OR 1.403, 95% CI 1.023-1.924) and neighboring gray-tone difference matrix (NGTDM) contrast (OR 0.692, 95% CI 0.493-0.971). Noteworthy, no significant differences in LGLZE (p = 0.94), GLN (p = 0.40) and NGDTM contrast (p = 0.54) were found between fractured subjects with BMD T score < - 2.5 SD and those in whom VFs developed in absence of densitometric diagnosis of osteoporosis. CONCLUSIONS: Artificial intelligence-based analyses on spine CT images identified RFs associated with fragility VFs. Future studies are needed to test the predictive value of RFs on opportunistic CT scans in identifying subjects with primary and secondary osteoporosis at high risk of fracture.

Attachment anxiety and the curvilinear effects of expressive suppression on individuals' and partners' outcomes.

Suppressing the expression of negative emotions tends to undermine individuals' and their partners' wellbeing. However, sometimes expressive suppression may be relatively innocuous given that individuals commonly withhold negative emotions in order to maintain close relationships, and this may be especially the case when expressive suppression is enacted by people who exhibit amplified expressions of negative emotions, such as those high in attachment anxiety. The current research examined when and for whom expressive suppression may be more or less costly by testing whether the curvilinear effect of individuals' expressive suppression on individuals' and partners' outcomes is moderated by individuals' attachment anxiety. Our results across 3 dyadic studies revealed a linear effect of expressive suppression when predicting individuals' outcomes: greater expressive suppression had costs for individuals (lower relationship satisfaction, reported responsiveness and discussion success, and greater discussion threat). Furthermore, in 4 of the 5 models, a moderated curvilinear effect of expressive suppression emerged when predicting partners' outcomes. For individuals low in attachment anxiety, low levels of expressive suppression did not incur costs for their partners' relationship satisfaction, perceptions of individuals' responsiveness, discussion success, and discussion threat. Once expressive suppression surpassed moderate levels, however, greater expressive suppression had a detrimental effect on partners' outcomes. In contrast, for individuals high in attachment anxiety, the negative effect of moderate-to-high levels of expressive suppression on partners' outcomes was attenuated. These novel results demonstrate how considering curvilinear methods can uncover when and for whom expressive suppression may be more or less costly in intimate relationships.

Assessing an Automatic Procedure of Extraction of Physiological Parameters from Skin using Video Photoplethysmography.

Video Photoplethysmography (vPPG) allows for estimation of blood volume pulse (BVP) from the skin by means of a video camera recording at high frequency rate. The estimation procedure presents several drawbacks in its application to real world conditions, such as light changes or movements that often generate artifacts in the extracted BVP waveform. In addition, the process requires a skin segmentation algorithm to distinguish skin pixels from the background. To date, even the most refined skin segmentation algorithms still need a manual definition that could lead to incorrect pixel classification, and consequently to a decrease in the signal-to-noise ratio (SNR). We here propose a fully autonomic procedure able to extract BVP from video recordings of the skin in real world conditions.The experimental protocol is designed to record the signals of interest and to evaluate changes in the Autonomic Nervous System modulation of the heart during a baseline condition and a controlled breathing phase. Video recordings are gathered from 4 young healthy subjects (age: 21±1 years). vPPG signals are processed in order to extract the BVP waveform, and a peak detection algorithm detects pulse wave peaks that are then used to compute specific measures of heart rate variability (HRV).The procedure is successfully validated by comparing the extracted HRV measures against those extracted using a finger photoplethysmograph (fPPG) using three different skin segmentation algorithms from BVP signals.

Look but don't touch?: Self-regulation determines whether noticing attractive alternatives increases infidelity.

People regularly encounter tempting alternatives to their relationship partners, and it has been argued that paying attention to desirable alternatives increases the risk of infidelity. However, whether the temptation of noticing attractive alternatives leads to actual infidelity should depend on the ability to resist such temptation. More specifically, taking heed of attractive others should increase the likelihood of infidelity only when people lack self-regulatory ability. One experiment and one longitudinal study of newlyweds both demonstrated that the implications of attending to attractive alternatives for infidelity depended on participants' self-regulatory ability to resist such temptations. Specifically, the tendency to notice attractive alternatives was associated with greater infidelity among those with poorer self-regulatory ability, but not among those with greater self-regulatory ability. These results further understanding about how people can maintain and protect their relationships in the face of temptation. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Romantic partners' working memory capacity facilitates relationship problem resolution through recollection of problem-relevant information.

Intimates often discuss the causes of, and solutions to, their relationship problems with their partners, and this information can shape partners' behavior and thus facilitate problem resolution. Partners' ability to encode and later recall such discussions should lead to greater declines in the severity of those problems. This brief report presents the results from a broader longitudinal study in which newlywed couples completed tasks assessing their working memory capacity (WMC), engaged in problem-solving discussions, recalled those discussions after a short delay, and then reported the severity of the problems discussed over the course of a year. Greater WMC among partners was associated with greater declines in the severity of a relationship problem, mediated by partners' recall of the discussion of that problem, suggesting that WMC facilitated the long-term memory encoding of the problem discussion. This study is among the first to suggest that individual differences in basic cognitive abilities may affect conversation processing and recall, and thereby close relationships.

The Relationship Problem Solving (RePS) Model: How Partners Influence One Another to Resolve Relationship Problems.

In this article, we synthesize existing literatures across numerous domains to introduce a novel model-the Relationship Problem Solving (RePS) model-for understanding the process through which romantic partners influence one another to resolve relationship problems. The first section briefly describes the key constructs and stages of the model. The second section details the interpersonal behaviors that influence various intrapersonal factors (e.g., affect, self-efficacy) that ultimately influence partners' motivation and ability to progress through the stages of the model. The third section uses the model to generate novel predictions that suggest that the effectiveness of these interpersonal behaviors often depends on contextual factors. Finally, the fourth section discusses the implications of this model for understanding relationship problem solving, highlights the need to consider the role of context in the problem-solving process, and offers numerous specific predictions to be addressed by future research.

Identification and Tracking of Physiological Parameters from Skin using Video Photoplethysmography.

In recent years, there has been a growing interest in video Photoplethysmography (vPPG), a technique able to estimate cardiovascular parameters from video recordings of the skin. Despite the growing interest in vPPG technology, there are still problems in extracting the correct waveform of blood volume pulse, mainly due to real world artifacts, such as changes in light condition and movement artifacts. Another important issue is the correct definition of skin against background. Therefore, we propose an algorithm of skin detection that is able to recognize skin pixels solid to variations of luminosity. We recorded the signals of interest during an experimental protocol designed to provide thermal stimulation and observe the resulting Autonomic Nervous System changes. Experimental data were gathered from 10 young healthy subjects (age: 21±2 years). Video recordings are processed using a band-pass filter and then an automatic algorithm of peak detection is applied to detect the pulse wave peaks, then used to estimate heart rate variability (HRV). The efficiency and stability of the algorithm are compared against finger-PPG waveforms. Preliminary results show an overall statistical agreement between time and frequency domain indexes. However, further efforts are required to improve the estimation of frequency components, particularly during rest.

Partners' depressive symptoms moderate the effects of expressive suppression.

Suppressing emotional expressions can hide one's needs from relationship partners and thus prevent partners from providing support. Nevertheless, suppressing expressions may help people maintain more favorable evaluations of partners who are ultimately unsupportive because people may attribute a lack of support to partners being unaware of their needs. Thus, given that depressive symptoms reduce provisions of support, people with partners experiencing depressive symptoms may remain more satisfied to the extent that they previously suppressed emotional expressions. We tested these ideas in 1 experiment, 1 cross-sectional study, and 1 longitudinal study. In Study 1, participants imagined either expressing or suppressing their emotions, imagined their partner was either supportive or unsupportive to their needs, and reported their perceptions of their partner. In Studies 2 and 3, newlywed couples reported their depressive symptoms, their marital satisfaction, and the extent to which they suppressed their emotional expressions cross-sectionally (Study 2) or every year for 2 years (Study 3). Results revealed that people with unsupportive partners or partners high in depressive symptoms made more benevolent attributions for their partners' unsupportive behavior and remained more satisfied with their partners to the extent that they suppressed their emotional expressions; however, people with supportive partners or partners low in depressive symptoms became more dissatisfied with their partners to the extent that they suppressed their emotional expressions. These results highlight the benefits of dyadic theoretical perspectives by revealing that qualities of the partner moderate the effects of expressive suppression.

Does support need to be seen? Daily invisible support promotes next day relationship well-being.

Direct and overt visible support promotes recipients' relationship satisfaction but can also exacerbate negative mood. In contrast, subtle and indirect invisible support can bypass costs to mood, but it is unclear whether it undermines or boosts relationship satisfaction. Because invisible support is not perceived by recipients, its relational impact may be delayed across time. Thus, the current research used three dyadic daily diary studies (total N = 322 married couples) to explore, for the first time, both the immediate (same day) and lagged (next day) effects of visible and invisible support on recipients' mood and relationship satisfaction. Consistent with prior research, visible support was associated with recipients reporting greater relationship satisfaction and greater anxiety the same day. In contrast, but also consistent with prior research, invisible support had no significant same-day effects, and thus avoided mood costs. Nevertheless, invisible support was associated with recipients reporting greater relationship satisfaction the next day. Study 3 provided evidence that such effects emerged because invisible support was also associated with greater satisfaction with partners' helpful behaviors (e.g., household chores) and relationship interactions (e.g., time spent together) on the next day. These studies demonstrate the importance of assessing different temporal effects associated with support acts (which may otherwise go undetected) and provide the first evidence that invisible support enhances relationship satisfaction but does so across days.

"You're forgiven, but don't do it again!" Direct partner regulation buffers the costs of forgiveness.

Although forgiveness can have numerous benefits, it can also have a notable cost-forgiveness can allow transgressors to continue behaving in ways that can be hurtful (McNulty, 2010, 2011). Accordingly, two studies tested the prediction that the implications of forgiveness for whether the partner transgresses or fails to behave benevolently depend on whether forgivers regulate partners away from future transgressions and toward benevolent behaviors. Study 1 was an experimental study of emerging adult couples in which participants were (a) asked to report their partners' tendencies to engage in partner-regulation behaviors, (b) led to believe their partners were either forgiving or unforgiving, and (c) given the opportunity to transgress against their partners. Study 2 was a longitudinal study of newlywed couples in which participants were (a) asked to report their tendencies to forgive their partners, (b) observed during problem-solving discussions, and then (c) asked to report their satisfaction with their partners' considerateness every 6 months for 4 years. Both studies provided evidence that direct oppositional partner-regulation behaviors moderate the implications of forgiveness for partner behavior. Among intimates who demanded more change, forgiveness was associated with the partner transgressing less (Study 1) and compromising more (Study 2), as well as participants being more satisfied with their partners' considerateness over time (Study 2); among intimates who demanded less change, forgiveness was associated with these outcomes in the opposite direction. These findings suggest that supplementing forgiveness with partner-regulation behaviors can help nondistressed couples avoid the undesirable outcomes and maximize desirable outcomes associated with forgiveness.

Neurocognitive functioning, clinical course and functional outcome in first-treatment bipolar I disorder patients with and without clinical relapse: A 1-year follow-up study.

OBJECTIVES: Due to limited research on the association between recurrence of mood episodes and the longitudinal course of neurocognitive functioning in early phase bipolar I disorder (BD I), the impact of recurrence on neurocognition remains unclear. Further, a strong correlation between neurocognitive impairment and functional impairment has been demonstrated. The longitudinal relationship between neurocognitive impairment and functional outcome in relation to recurrence is, however, not established. METHODS: The current study investigated the longitudinal relationship between neurocognition, recurrence of mood episodes and functional outcome in a sample of first-treatment (FT) BD I patients (N = 42), with and without relapse, during a 1-year follow-up period. The longitudinal course of neurocognitive functioning in the patients was also compared to that of a group of healthy controls (N = 143). RESULTS: Compared to both patients with relapse and healthy controls, no-relapse patients showed neurocognitive improvements. The polarity of the relapse episodes was mostly depressive, and for the no-relapse patients, reduction of symptoms was associated with neurocognitive improvement. No-relapse patients showed better global and occupational functioning. CONCLUSIONS: The current study found different neurocognitive and functional trajectories in FT BD I patients with and without relapse, with differences at follow-up to some degree being mediated by current symptoms. The current findings highlight the importance of treatment focusing on neurocognition and symptom states with the aim of improving functional recovery.

Personal and couple level risk factors: Maternal and paternal parent-child aggression risk.

Previous literature examining parent-child aggression (PCA) risk has relied heavily upon mothers, limiting our understanding of paternal risk factors. Moreover, the extent to which factors in the couple relationship work in tandem with personal vulnerabilities to impact PCA risk is unclear. The current study examined whether personal stress and distress predicted PCA risk (child abuse potential, over-reactive discipline style, harsh discipline practices) for fathers as well as mothers and whether couple functioning mediated versus moderated the relation between personal stress and PCA risk in a sample of 81 couples. Additionally, the potential for risk factors in one partner to cross over and affect their partner's PCA risk was considered. Findings indicated higher personal stress predicted elevated maternal and paternal PCA risk. Better couple functioning did not moderate this relationship but partially mediated stress and PCA risk for both mothers and fathers. In addition, maternal stress evidenced a cross-over effect, wherein mothers' personal stress linked to fathers' couple functioning. Findings support the role of stress and couple functioning in maternal and paternal PCA risk, including potential cross-over effects that warrant further inquiry.

Expectations for future relationship satisfaction: Unique sources and critical implications for commitment.

Contemporary perspectives on relationship commitment posit that intimates decide whether or not to maintain a relationship based on their commitment to that relationship, and that they base such commitment partially on their current satisfaction with that relationship. Nevertheless, given that ending a relationship requires knowing about both the current state of the relationship and the likely future state of the relationship, we propose that people base their commitment to a relationship more on their expected future satisfaction with the relationship than on their current satisfaction with that relationship. Six studies provided evidence for these ideas. Study 1 demonstrated that expected satisfaction is shaped by not only current satisfaction but also several unique indicators of the likelihood of future satisfaction, including anticipated life events, plans to improve the relationship, and individual differences. Then, using a combination of cross-sectional, experimental, and longitudinal methods, Studies 2 through 6 demonstrated that (a) expected satisfaction was a stronger predictor of relationship commitment, maintenance behaviors, and/or divorce than was current satisfaction and (b) expected satisfaction mediated the association between current satisfaction and these outcomes. These findings highlight not only the need to incorporate expected satisfaction into extent perspectives on commitment, but also the importance of expectations for decision-making processes more broadly.

Course of neurocognitive function in first treatment bipolar I disorder: One-year follow-up study.

Neurocognitive impairment has been found to be a marked feature in bipolar disorder (BD), also in the early phase of the illness. The longitudinal course of neurocognitive functioning, however, remains sparsely investigated. The aims of the study were to investigate the course of neurocognitive function in BD I, and to what degree neurocognitive change or stability is observed also on the individual level. Forty-two patients and 153 comparable healthy controls were assessed at baseline and one-year follow-up. Compared to the healthy control (HC) group BD I patients perform significantly poorer at both baseline and follow-up across all neurocognitive domains and on most neurocognitive subtests. Neurocognitive impairment remained stable for most patients from baseline to follow-up, both on a group level and when investigating individual trajectories, indicative of a relatively stable course of neurocognitive functioning in the early phase of BD I.
