ABSTRACT

Functional seizures (FS) are seizure-like symptoms without electroencephalogram (EEG)-based epileptic activity. Those with FS often show emotion-related dysfunction and disrupted interpersonal relationships, in which posttraumatic stress disorder symptoms (PTS) may play a role. We sought to better understand trauma comorbidities and socioemotional processes in FS, including affectionate touch, a form of social connection linked to emotion regulation and awareness. We administered questionnaires online to a community sample of 89 trauma-exposed FS participants (FS diagnoses were self-reported), 51 with and 38 without clinical-level PTS (FS-PTShi, FS-PTSlo) and 216 seizure-free matched trauma-exposed controls (TCs), 91 with and 125 without clinical-level PTS (TC-PTShi, TC-PTSlo) per the Posttraumatic Stress Disorder Symptom Checklist (PCL). As hypothesized, both FS-PTShi and FS-PTSlo reported more emotional avoidance (Brief Experiential Avoidance Questionnaire), more emotion regulation difficulties (Difficulties in Emotion Regulation Scale), and more perceived stress (Perceived Stress Scale) than PTS-matched counterparts. FS-PTShi also reported less reappraisal (Emotion Regulation Questionnaire), more loneliness (UCLA Loneliness Scale), and less frequent affectionate touch (Physical Affection Scale) during waking and surrounding sleep than TC-PTShi, whereas FS-PTSlo and TC-PTSlo did not differ. Neither FS group differed from PTS-matched controls in emotion suppression (Emotion Regulation Questionnaire) or comfort with social touch (Social Touch Questionnaire). Among FS, FS-PTShi reported more difficulties than FS-PTSlo on nearly all measures (non-significant trend for social support). Findings underscore potential synergistic effects of FS and PTS clinical symptoms in shaping experiences of one's emotions and social world, suggesting fostering meaningful connections with others, including via affectionate touch, is an important treatment target.

ABSTRACT

Touch associated with sleep (sleep-touch; reported physical contact during or shortly before/after sleep) is underexplored as a distinct contributor to affect regulatory processes associated with adult sleep. Given the affect-regulating effects of interpersonal touch, we theorized that among healthy co-sleeping adults, sleep-touch would add to sleep-related effects on affective "resetting," resulting in the experience of calmer, more regulated states. We studied 210 married heterosexual couples (aged 20-67 years, 79% non-Hispanic white, 13% Latinx) assigned 14 days of twice-daily (morning/evening) sleep/mood diaries. Multilevel daily (within-couple) mediation analyses showed that as hypothesized, more reported sleep-touch was associated with happier/calmer and less angry/irritable morning mood. In turn, happier/calmer mood was associated with greater enjoyment of time with spouse (for both spouses). Sleep-touch also was linked directly to both evening positive spousal events and enjoyment ratings. Sleep-touch was associated indirectly with fewer negative spousal events and less spouse-related stress via less angry/irritable morning mood (both spouses). Further, wives' sleep-touch was related to happier/calmer husband mood and evening enjoyment; husbands' sleep-touch was unrelated to wives' reports. All associations with sleep-touch were present while accounting for subjective sleep quality, prior evening mood, non-sleep-related physical affection, day in study, and weekend versus weekday. We speculate that among relatively healthy satisfied couples, physical touch during and surrounding sleep may add to sleep's restorative and affect-regulatory functions, suggesting a pathway through which co-sleeping can improve affect regulation and ultimately relationships and health.

ABSTRACT

Existing literature shows conflicting and inconclusive evidence regarding women's sexual experiences in casual sex. Some studies have found negative sexual outcomes (e.g., fewer orgasms), while others have found positive sexual outcomes (e.g., more orgasms, higher sexual satisfaction) when women had casual sex. According to self-determination theory (Deci & Ryan, 1985), people's needs are fulfilled when their choice and behavior are self-motivated and reflect their intrinsic values. We hypothesized that women's autonomous motivation to have casual sex would be associated with higher orgasmic function, whereas nonautonomous motivation would be associated with lower orgasmic function in casual sex. We also hypothesized that sexual assertiveness would mediate the relationship between sexual motives and orgasmic function in casual sex. Participants in this study were women (N = 401) aged 18-59 years who reported having had casual sex in the past 12 months. Participants completed an online survey reporting their motives to have casual sex, sexual assertiveness, and orgasmic function (e.g., orgasm frequency, satisfaction with orgasm) in casual sex. We focused on two motives: (a) pleasure motive and (b) insecurity (i.e., self-esteem boost and pressure) motive. Results showed that greater pleasure (autonomous) motives related to higher sexual assertiveness, which in turn related to higher orgasmic function in casual sex. In contrast, greater insecurity (nonautonomous) motives related to lower sexual assertiveness, which in turn related to lower orgasmic function in casual sex. The findings support self-determination theory, suggesting that autonomous motives are important for women's sexual experience in casual sex.

ABSTRACT

John Cacioppo and colleagues' Somatovisceral Afference Model of Emotion (SAME) highlighted the importance of interoception in emotional experience. Here we compare how the SAME and the more recent theory of constructed emotion (TCE) view the role of interoceptive signals in creating emotional experiences. We describe the characteristics of touch sensations that are carried by thin, unmyelinated fibers called C-tactile afferents (CTs) to the posterior insula, and are thus deemed interoceptive despite their typically social (external) origin. We explore how this social interoceptive input might contribute to the emotion-related effects of social touch more generally, and speculate that all social touch, with or without CT afferent stimulation, can directly influence allostasis, or the predictive regulation of short- and long-term energy resources required by the body. Finally, we describe several features of CT-optimal touch that make it a potentially useful tool to help illuminate basic interoceptive mechanisms, emotion-related phenomena, and disorders involving atypical affect or somatosensation. These proposed ideas demonstrate the long intellectual reach of John Cacioppo and Gary Berntson's highly productive scientific collaboration, which was formative for the fields of social neuroscience, social psychophysiology, and affective neuroscience.

ABSTRACT

This study investigated the feasibility and preliminary effectiveness of a pilot program designed to address subjective memory complaints among Veterans. The program, Brain Boosters, consisted of 10 once-weekly group sessions, during which psychoeducation and cognitive enhancement strategies were used to target memory concerns and related processes, specifically attentional difficulties. Given that memory complaints often are associated with psychiatric comorbidities, sessions also incorporated strategies for reducing symptoms of depression, posttraumatic stress, and insomnia. Controlling for age, we examined pre- to posttreatment change in symptom ratings for 96 Veterans (aged 22 to 87 years) who participated in the Brain Boosters program. The effect of Brain Boosters on memory complaints interacted with age: younger (but not older) Veterans reported reductions in memory impairment from pre- to posttreatment. Additionally, irrespective of age, from pre- to posttreatment Veterans reported fewer attentional difficulties and fewer depression symptoms. Ratings of posttraumatic stress and insomnia symptoms did not change, although insomnia was negatively associated with age. Linear regression controlling for age revealed that reductions in attention problems predicted reductions in perceived memory impairment. Findings from this exploratory, uncontrolled pilot study suggest that a psychoeducational cognitive enhancement group is feasible to conduct in a heterogeneous Veteran population, and may be associated with improvements in perceived memory functioning for younger Veterans, and in attention and depression symptoms for Veterans across age groups.

ABSTRACT

Previous studies have found that women report more orgasm and sexual satisfaction from sex in committed relationships than from casual sex. We examined whether sociosexual orientation was associated with these differences, and explored the links between sociosexuality and sexual outcomes in these two sexual relationship contexts. Sexually active women (n = 1,084) completed an online survey measuring sociosexual orientation, orgasmic function, and sexual satisfaction. Participants reported sexual outcomes (orgasmic function and sexual satisfaction) with respect to their sexual activity over the past 12 months in a casual context (if applicable), and separately in a committed context (if applicable). Among women who had both casual and committed sex in the past year, orgasmic function and sexual satisfaction differed between these two relationship contexts only for more sexually restricted women (lower sociosexuality). In the full sample, higher sociosexuality was associated with higher orgasmic function in casual sex and with lower sexual satisfaction in committed sex. These findings underscore the importance of examining interactions between individual differences and contextual factors when studying women's sexual outcomes.

ABSTRACT

OBJECTIVE: Dysfunction in emotional processes is a hypothesized contributor to functional neurological disorders (FNDs), yet few studies have evoked real-time emotion during multimethod assessment incorporating subjective, behavioral, and psychophysiological indicators. This approach may reveal clinical and neurobiological vulnerability to FND and clarify how dysfunctional emotional processes serve as perpetuating factors. METHODS: Eleven participants with video-EEG-confirmed diagnoses of psychogenic nonepileptic seizures (PNES) were compared with 49 seizure-free trauma control subjects (TCs) with or without clinically elevated posttraumatic stress symptoms (25 clinically elevated [TC-clin], 24 not clinically elevated [TC-nonclin]). Participants recalled and described memories evoking anger, shame, happiness, and neutral feelings. RESULTS: Even though PNES patients and TCs reported similar amounts of emotional experience, PNES patients reported more difficulty reliving emotions and were less likely to complete the relived shame task. During and after reliving happiness, PNES and TC-clin groups showed respiratory sinus arrhythmia (RSA) decreases, indicating parasympathetic withdrawal, whereas the TC-nonclin group showed RSA increases. CONCLUSIONS: Findings from this pilot study are consistent with previous research and clinical observations that emotional engagement may be more effortful for PNES patients. Patterns of RSA change, which may also point to greater effortful engagement, were similar in PNES and TC-clin groups, suggesting that traumatic stress reactions may play a part. At the same time, experience of greater difficulty or avoidance may be even greater among PNES patients. Especially when regulatory resources are already limited, accumulated effort, coupled with self-threatening contexts such as shame, may be particularly problematic for those with PNES and perhaps other FNDs.

ABSTRACT

Psychological assessment measures are frequently used to evaluate patients in epilepsy monitoring units. One goal of that assessment is to contribute information that may help with differential diagnosis between epilepsy and psychogenic nonepileptic seizures (PNES). The Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) is one such measure. Del Bene et al. (2017) recently published an analysis that was the first to compare MMPI-2-RF scale elevations between diagnostic groups stratified by sex. The purpose of the present study was to replicate that analysis in a larger sample. Similar to previous work, we found that both men and women with PNES were more likely than men and women with epilepsy to report high levels of somatic complaints (2 to 5 times greater odds of somatic symptom reporting) and a variety of types of complaints. Mood disturbance scales were not significantly elevated in our PNES sample. Results contribute to the small body of research on sex differences in patients with PNES and suggest that somatization is a key characterization across sexes.

ABSTRACT

Cultural and ethnic identities influence the relationships individuals seek out and how they feel and behave in these relationships, which can strongly affect mental and physical health through their impacts on emotions, physiology, and behavior. We proposed and tested a model in which ethnocultural identifications and ingroup affiliations were hypothesized explicitly to enhance social connectedness, which would in turn promote expectancy for effective regulation of negative emotions and reduce self-reported symptoms of depression and anxiety. Our sample comprised women aged 18-30 currently attending college in the Southwestern US, who self-identified as Hispanic of Mexican descent (MAs; n = 82) or as non-Hispanic White/European American (EAs; n = 234) and who completed an online survey. In the full sample and in each subgroup, stronger ethnocultural group identity and greater comfort with mainstream American culture were associated with higher social connectedness, which in turn was associated with expectancy for more effective regulation of negative emotions, fewer depressive symptoms, and less anxiety. Unexpectedly, preference for ingroup affiliation predicted lower social connectedness in both groups. In addition to indirect effects through social connection, direct paths from mainstream comfort and preference for ingroup affiliation to emotion regulation expectancy were found for EAs. Models of our data underscore that social connection is a central mechanism through which ethnocultural identities-including with one's own group and the mainstream cultural group-relate to mental health, and that emotion regulation may be a key aspect of this linkage. We use the term ethnocultural social connection to make explicit a process that, we believe, has been implied in the ethnic identity literature for many years, and that may have consequential implications for mental health and conceptualizations of processes underlying mental disorders.

ABSTRACT

We examined emotional responses to standard affective pictures in 18 psychogenic nonepileptic seizure (PNES) patients. Given reports of trauma and posttraumatic stress symptoms (PTS) in many PNES patients, comparison groups were seizure-free individuals high and low in PTS (PTS-high, PTS-low; n=18 per group). Patients with psychogenic nonepileptic seizures (1) reported more emotional intensity to neutral and pleasant pictures than PTS-low and more intensity to neutral pictures than PTS-high, and (2) showed less positive emotional behavior to pleasant pictures than PTS-high. Groups did not differ in pleasantness/unpleasantness ratings, negative emotional behavior, cardiac interbeat interval, or respiratory sinus arrhythmia (RSA) reactivity to the pictures. Patients with psychogenic nonepileptic seizures reported more general emotion regulation difficulties and showed lower baseline RSA than PTS-low but not PTS-high. In sum, intense emotional experience and diminished positive emotional behavior characterized PNES patients' emotional responses.

ABSTRACT

Emotion research historically has adopted a fairly homogeneous view of positive emotions. The aim of the current study was to explore how two positive emotions, amusement and joy, differ in subjective, behavioral, cardiovascular, and respiratory characteristics. Thirty-nine participants viewed two film clips, each selected to elicit amusement or joy. As predicted, participants reported more amusement, showed more positive facial expressions and laughter, and exhibited less heart rate deceleration and a larger increase in respiratory amplitude in response to the amusement clip than in response to the joy clip. In addition, subjective, behavioral, and physiological indicators were more closely related in amusement than joy, which was largely attributable to laughter during amusement. The current study adds to a growing literature suggesting the importance of adopting a more nuanced conceptualization of positive emotion.

ABSTRACT

OBJECTIVE: The aim of this study was to investigate the relationships among daily reports of vasomotor symptoms (hot flashes and/or sweats), same-day sleep problems, and next-day mood reports in middle-aged women. METHODS: Fifty-five healthy middle-aged women were recruited to keep daily records for up to 5 years or until menopause. For each participant, the first 252 days of contiguous data with the highest weekly frequency of vasomotor symptoms was selected for the current analyses. Multilevel structural equation modeling was used to test whether changes in daily vasomotor symptom occurrence predicted changes in occurrence of same-day sleep problems and changes in next-day positive and negative mood ratings and whether sleep problems mediated any predictive effect of symptoms on next-day mood. RESULTS: Controlling for initial depression, daily vasomotor symptoms predicted same-day sleep problems (b = 0.59, P < 0.001) and next-day positive mood (b = -0.07, P < 0.01), although significant direct relationships between vasomotor symptoms and mood were found primarily in women with initial depression scores in the low to moderate range. Sleep problems predicted next-day positive (b = -0.08, P < 0.01) and negative (b = 0.10, P < 0.001) mood more robustly than vasomotor symptoms did. CONCLUSIONS: Sleep problems predicted worse mood on the following day and accounted for only a small portion of the relationship between vasomotor symptoms and mood. These findings suggest that any effect of vasomotor symptoms on mood may occur largely through a mechanism other than sleep disruption.

ABSTRACT

How do physical affection, sexual activity, mood, and stress influence one another in the daily lives of mid-aged women? Fifty-eight women (M age, 47.6 yrs) recorded physical affection, several different sexual behaviors, stressful events, and mood ratings every morning for 36 weeks. Using multilevel modeling, we determined that physical affection or sexual behavior with a partner on one day significantly predicted lower negative mood and stress and higher positive mood on the following day. The relation did not hold for orgasm without a partner. Additionally, positive mood on one day predicted more physical affection and sexual activity with a partner, but fewer solo orgasms the following day. Negative mood was mostly unrelated to next-day sexual activity or physical affection. Sexual orientation, living with a partner, and duration of relationship moderated some of these effects. Results support a bidirectional causal model in which dyadic sexual interaction and physical affection improve mood and reduce stress, with improved mood and reduced stress in turn increasing the likelihood of future sex and physical affection.

ABSTRACT

We report long-term temporal consistency of stress-related neuroendocrine and cardiovascular variables in mid-aged and older women who performed mental math and speech stress tasks two times approximately 1 year apart. Epinephrine, norepinephrine, ACTH, cortisol, cardiac preejection period (PEP), respiratory sinus arrhythmia, heart rate (HR), blood pressure, and respiration rate were measured at baseline, after or during stressors, and 30 min posttask. Although there were exceptions, year-to-year Spearman coefficients showed mostly moderate to high consistency (rs approximately equal to .5-.8) for baseline, stressor, and posttask values. For reactivity, HR and PEP were most consistent (rs approximately equal to .65); consistency for other variables was moderate to low (rs approximately equal to .1-.4). Means of most variables changed from year to year. Results support the use of baseline, stressor, and posttask values in longitudinal studies.

ABSTRACT

Prior lab research revealed higher basal total peripheral resistance (TPR) and lower cardiac output (CO) in lonely than in nonlonely young adults. In this study, experience sampling was used to obtain ambulatory blood pressure; impedance cardiography: and reports of activities, appraisals, interactions, and health behaviors. Results confirmed that loneliness predicted higher TPR and lower CO during a normal day. Loneliness did not predict differences in time spent alone, daily activities, or health behaviors but did predict higher stress appraisals and poorer social interactions. Independent of loneliness, interaction quality contributed to TPR. Loneliness differences were not mediated by depressed affect or neuroticism. Social support mediated loneliness differences in stress and threat. Concomitants of loneliness were comparable for men and women.

ABSTRACT

Previous studies have demonstrated the impact of psychological stress on the steady-state expression/reactivation of latent Epstein-Barr virus (EBV). Stress-induced decrements in the cellular immune response result in less control over the expression of the latent virus, resulting in increases in antibody to the virus. In Study 1, we investigated whether the steady-state expression of latent EBV in vivo differed between high and low stress reactors, as defined by sympathetic cardiac reactivity. Autonomic activity and antibody titers to Epstein-Barr virus capsid antigen (VCA) were measured in 50 elderly women latently infected with EBV. Results revealed that women who were high stress reactors were characterized by higher antibody titers to the latent virus than low stress reactors. High reactors tended to show larger stress-related increases in cortisol than low reactors, but the differences were not significant. Daily stressors can activate the autonomic nervous system and promote the release of pituitary and adrenal hormones, especially in high reactors. Glucocorticoid hormones have been shown to reactivate EBV in vitro from cells latently infected with the virus. We hypothesized that absolute levels of plasma cortisol may not be the only explanation for stress-induced reactivation of latent EBV and that the diurnal changes in the production of cortisol may be an important factor in these interactions. To examine the feasibility of this hypothesis, an in vitro study was conducted (Study 2) to determine whether changing glucocorticoid concentrations in the medium, in which EBV latently infected cells were cultured, to mimic diurnal changes in plasma cortisol concentrations would enhance the reactivation of the latent virus. Cells latently infected with EBV were exposed to either constant or varying concentrations of the synthetic glucocorticoid hormone dexamethasone (Dex), for 72 h. Results revealed a three- to eightfold enhancement of reactivation of latent EBV in cells pulsed with varying Dex concentrations when compared with cells exposed to a constant and/or a higher mean level of one Dex concentration. Together, these studies raise the possibility that differences in the kinetics of glucocorticoid concentrations may contribute to differences in the reactivation of latent EBV.

ABSTRACT

This study reviews prior research and reports longer-term consistency of stress-related immune variables in middle-aged and older women who performed mental math and speech tasks 2 times 1 year apart. Leukocyte subsets, mitogen-induced lymphocyte proliferation, and natural killer cell activity were measured at baseline, after tasks, and after 30-min recovery. Epstein-Barr virus (EBV) antibody titers were assessed at baseline. Pearson coefficients and standardized maximum-likelihood estimates of year-to-year covariances for leukocyte subsets and EBV titers showed moderately high to high baseline and posttask consistency and lower recovery consistency; consistency for other functional immune assays and reactivity scores for all variables was moderate to low. Results support longitudinal study of psychosocial context effects on tonic immune function and posttask scores.

ABSTRACT

OBJECTIVE: Two studies using cross-sectional designs explored four possible mechanisms by which loneliness may have deleterious effects on health: health behaviors, cardiovascular activation, cortisol levels, and sleep. METHODS: In Study 1, we assessed autonomic activity, salivary cortisol levels, sleep quality, and health behaviors in 89 undergraduate students selected based on pretests to be among the top or bottom quintile in feelings of loneliness. In Study 2, we assessed blood pressure, heart rate, salivary cortisol levels, sleep quality, and health behaviors in 25 older adults whose loneliness was assessed at the time of testing at their residence. RESULTS: Total peripheral resistance was higher in lonely than nonlonely participants, whereas cardiac contractility, heart rate, and cardiac output were higher in nonlonely than lonely participants. Lonely individuals also reported poorer sleep than nonlonely individuals. Study 2 indicated greater age-related increases in blood pressure and poorer sleep quality in lonely than nonlonely older adults. Mean salivary cortisol levels and health behaviors did not differ between groups in either study. CONCLUSIONS: Results point to two potentially orthogonal predisease mechanisms that warrant special attention: cardiovascular activation and sleep dysfunction. Health behavior and cortisol regulation, however, may require more sensitive measures and large sample sizes to discern their roles in loneliness and health.

ABSTRACT

Using a prospective design over three complete menstrual cycles, 147 heterosexual and 89 lesbian women made daily recordings of their basal body temperature (BBT), cervical mucus status, menses, and completed a daily checklist of various sexual behaviors (including sexual self-stimulation and sexual activity with a partner). They also gave their age, height, weight, age at menarche, number of pregnancies, duration of sleep, tobacco, caffeine, and alcohol use, and whether they had a live-in sexual partner. Using BBT, cervical mucus status, and menses information, cycle days were grouped into five discrete phases: menses, follicular, ovulatory, early luteal, and premenstrual. Daily frequencies of sexual behavior with a partner and autosexual behavior were computed for each phase. Mixed ANOVAs on the resultant proportional data revealed similar patterns for autosexual behavior across the phases for both heterosexuals and lesbians who did not have a live-in partner, in which autosexual behavior was highest during the follicular and ovulatory phases. For those with live-in partners, autosexual behavior did not vary across the phases. Lesbians engaged in more autosexual behavior overall. Allosexual behavior peaked during the follicular phase for both heterosexuals and lesbians, and the phasic pattern was unrelated to live-in partner status. Additional analyses suggest that the observed patterns were unrelated to anticipated changes in sexual activity due to menses. Results are discussed in terms of social variables and hormonal fluctuations associated with the menstrual cycle.
