Pupil Constrictions and Their Associations With Increased Negative Affect During Responses to Recalled Memories of Interpersonal Stress

Abstract. Pupil diameter change is indicative of emotional processing. Most previous findings regarding pupillary response and emotion have reported that the pupil enlarges in response to the presentation of emotional perceptual stimuli (e.g., visual images) within several seconds. It is considered that such stimuli activate the sympathetic nervous system, leading to pupil dilation. In order to examine the effects of emotions similar to daily emotional experiences of mood, the present study examined pupil diameter changes and their relationships with subjective emotional changes while recalling a topic of stressful interpersonal events in daily life. The data of 20 university students (11 males, Mage = 20.36 ± 2.38 years; 9 females, Mage = 22.33 ± 3.57) were analyzed. In the experimental task, participants were instructed to recall their memories concerning the topic through instructions and questions presented on a monitor, which proceeded at their own pace, through a key press. Subsequently, after baseline and instruction periods, participants were instructed to freely recall their memories. They were then asked to respond silently to a series of questions concerning the freely recalled memories. In the analysis, we compared the pupil diameters between these different periods and observed that pupil diameters significantly decreased during the response period relative to the free recall or baseline periods. Furthermore, pupil constrictions during the response period were negatively correlated with increases in negative affect scale scores. Pupil constriction, which is indicative of decreased arousal level and parasympathetic activation, was presumably caused by multiple factors including less cognitive difficulty and a relatively long experimental task period. As the result of a less tonic mode in the response period, the attention of participants might be more successfully focused on ongoing tasks, which might lead to optimal performance in recalling memories, possibly leading to correlations between pupil diameter and negative emotional changes.

Examining quality of life in an Australian cohort of people with epilepsy over six years — Understanding the role of stigma and mood

AimResearch examining quality of life (QoL) among people living with epilepsy (PWE) consistently highlights the detrimental impact of stigma, anxiety, and depression, as well as the dynamic and changing nature of QoL over time. This paper represents the first panel study of the Australian Epilepsy Longitudinal Survey (AELS), examining factors that influence the QoL of PWE over a six-year interval, particularly focusing on experiences of stigma, depression, and anxiety. MethodsNinety-two adults participated in both Wave 2 (T1; 2010) and Wave 4 (T2; 2016/17) of the AELS. Average age at T2 was 53.4 years [standard deviation (SD) = 15.3; range: 22–82; 55% female]. Over the study interval, there was a shift towards more younger participants moving out of high school and older participants moving into retirement. We explored the impact of (i) experiences of stigma, (ii) mood, and (iii) sociodemographic factors on QoL at both T1 and T2 via the use of correlation analyses. Hierarchical regression was used to determine the strongest predictors of QoL at T2. ResultsOccurrence of recent seizures, stigma, anxiety, and depression measured at T1 were all significantly correlated with total QoL at both T1 and T2. Sociodemographic factors including years of education, and weekly income before tax were not significantly correlated with QoL at either T1 or T2. QoL and depression at T1 were identified as the strongest predictors of QoL at T2 (six years later). DiscussionThe current study supports previous research highlighting the importance of psychological factors in understating QoL in PWE, particularly stigma, anxiety, and depression. In particular, it highlights the impact of depression on QoL over a 6-year interval, providing evident for the long-term nature of this relationship.

The Relationship Between Hostile Interpretation Bias and Symptoms of Depression and Social Anxiety: a Replication Across Two Samples

Cognitive models of social anxiety and depression posit that hostile interpretation bias may be a symptom of, and act as a maintenance factor for, these disorders. Social anxiety and depression are also associated with increased experience of angry and irritable mood. To investigate whether hostile interpretation bias is related to symptoms of the disorder or to irritability, the current study investigated the degree to which state irritable mood may influence these relationships. In two samples, MTurk workers (Sample 1, n = 145) and college students (Sample 2, n = 387), we assessed depression symptoms, social anxiety symptoms, irritable mood, and hostile interpretation bias. In sample 1, depression and social anxiety symptoms were positively associated with hostile interpretation bias. When statistically controlling for irritable mood, depression symptoms no longer significantly predicted hostile interpretation bias. However, social anxiety remained a significant predictor of hostile interpretation bias even when controlling for irritable mood. The pattern of results was identical in sample 2. Results indicate that the association between depression symptoms and hostile interpretation bias may be accounted for by irritable mood, but social anxiety symptoms have a unique association with hostile interpretation bias even when including irritable mood. Clinical implications and future directions are discussed.

Measuring the working experience of doctors in training

Using an online tool, we report the association between tasks and 'affect' (underlying experience of feeling, emotion or mood) among 565 doctors in training, how positive and negative emotional intensity are associated with time of day, the extent to which positive affect is associated with breaks, and consideration about leaving the profession. Respondents spent approximately 25% of their day on paperwork or clinical work that did not involve patients, resulting in more negative emotions. Positive emotions were expressed for breaks, staff meetings, research, learning and clinical tasks that involved patients. Those having considered leaving the profession report more negative feelings. Systematic workplace changes (regular breaks, reducing paperwork and improved IT systems) could contribute to positive workday experiences and reduce intention to quit. Educators and employers have important roles in recognising, advocating for and implementing improvements at work to enhance wellbeing with potential to improve retention of doctors in training.

Do you feel like me or not? This is the question: manipulation of emotional imagery modulates affective priming

Mood congruity and affective priming have been used to study the effects of affective phenomena on perception. Manipulation of mood is appropriate for investigations of long-term effects while affective priming is limited to short intervals (approximately 300ms) between a prime and target. However, studying the influence of real-world rapidly changing emotional episodes on perception may fall between the cracks of these methods. This may be caused, inter alia, because emotional episodes are distinguished from mood experiences on one hand, but often last for longer than roughly 300ms on the other. Thus, it is unclear what experimental approach should be taken to investigate congruency effects triggered by emotional episodes. The present study used a new variation of the evaluation decision task (EDT) combined with a script-driven imagery procedure to investigate a possible congruency relationship between the evaluator's emotional experience at a given time and observable emotional markers of others. We used 180 9-word script-driven imageries as varying valence primes (negative, positive, neutral) and asked participants to imagine themselves in the situation described in the scripts. At the last stage of a trial, all participants were asked to evaluate the mood-positive or negative-of a target face of a child in a photograph. We manipulated the reading interval (4000ms and 1350ms) and the subsequent blank interval (300ms, 5000ms, and unlimited) until target onset. Prime and target valence were congruent or incongruent. Significant congruency effects were found for both short and long reading intervals and blank intervals. However, in longer blank intervals only the interference effect reached significance. Furthermore, the interference effect was found to be significant mainly in trials beginning with a negative script.

\u2018I Felt Like I was Floating in Space\u2019: Autistic Adults\u2019 Experiences of Low Mood and Depression

It is recognised that a high proportion of adults on the autism spectrum experience depressive symptoms. However, limited research has explored autistic peoples’ experiences of low mood and depression. The aim of this study was to explore the lived experiences of low mood and depression for adults on the autism spectrum. The study employed Interpretive Phenomenological Analysis to investigate the experiences of 8 adults (7 males and 1 female), aged between 19 and 51, who had a diagnosis of autism without co-occurring learning disabilities, and experienced low mood or depression. All participants recorded their thoughts and feelings in a mood diary for 1 week and participated in a semi-structured interview. Three superordinate themes emerged from the data: ‘Autism has made me the person I am’, ‘I can’t function in the world’ and ‘It’s like trying to do accounts on the futures market’: Making sense of emotions. Findings highlight a need for specialist mental health provision for adults who are on the autism spectrum. Limitations of this study and implications for future research are discussed.

Sceletium tortuosum (Zembrin® ) ameliorates experimentally induced anxiety in healthy volunteers.

To investigate the anxiolytic properties of a standardized extract of Sceletium tortuosum (trademarked-Zembrin® ). Two studies utilized a placebo-controlled, double-blind, between-subject experimental design to investigate the effects of a single dose of Sceletium tortuosum (25 mg, Zembrin® ) on laboratory stress/anxiety responding in 20 young healthy volunteers. To elicit feelings of stress/anxiety, participants completed 20 min of the multitasking framework in study 1 and a 5-min simulated public speaking task in study 2. Study 1 measured subjective experiences of mood at baseline, prestress induction, and poststress induction. Study 2 measured subjective experiences of anxiety and physiological indicators of stress (heart rate [HR] and galvanic skin response) at baseline, prestress induction, during stress induction, and poststress induction. A series of analysis of covariances (baseline entered as the covariate) revealed no treatment effect in study 1; however, study 2 revealed subjective anxiety levels to be significantly lower in the Zembrin® group at the prestress induction point and a significant interaction between treatment and time on HR. Taken together, results indicate that a single dose of Zembrin® can ameliorate laboratory stress/anxiety responding in healthy volunteers. We provide the first tentative behavioral evidence to support the anxiolytic properties of Sceletium tortuosum (25 mg Zembrin® ).

Unraveling Fatigue in Hemodialysis Patients: Comparing Retrospective Reports to Real-Time Assessments With an mHealth Experienced Sampling Method

ContextFatigue is prevalent among hemodialysis (HD) patients and associated with depressive mood. To advance our understanding of its etiology and develop appropriate treatments, reliable measurement instruments are needed. However, conventional fatigue and mood questionnaires are prone to bias because of their retrospective nature and may misrepresent or overestimate actual symptom experience (i.e., the so-called memory-experience gap). Experience sampling methodology (ESM) overcomes this limitation through repeated real-time assessments in patients' natural environment, thereby providing reliable and ecologically valid data. ObjectivesWe investigated to what extent retrospective symptom reporting accurately represents real-time experiences of fatigue and mood in HD patients using an ESM mobile Health application (PsyMate™; smartHealth GmbH, Luxembourg). MethodsForty HD patients used the PsyMate for one week to assess real-time fatigue and mood. In addition, they retrospectively evaluated their symptom experience completing end-of-day and end-of-week questionnaires as well as the conventional Fatigue Severity Scale and Hospital Anxiety and Depression Scale. ResultsResults of real-time observations (N = 1777) showed that fatigue and mood varied between and within individuals. Retrospective end-of-week fatigue evaluation was significantly higher than the average real-time fatigue score; t(38) = 3.54, P = 0.001, and d = 0.57. Fatigue Severity Scale and Hospital Anxiety and Depression Scale correlated moderately to strong with the average ESM score for fatigue and mood: r = 0.66 and r = 0.77, respectively. ConclusionRetrospective fatigue assessment may lead to overestimation of real-time symptom experience. ESM provides detailed insight and personalized information about symptom experiences, which may be crucial for the design of more targeted and personalized interventions for fatigue and mood problems in HD patients.

Prediction of Suicidal Ideation among Korean Adults Using Machine Learning: A Cross-Sectional Study.

ObjectiveSuicidal ideation (SI) precedes actual suicidal event. Thus, it is important for the prevention of suicide to screen the individuals with SI. This study aimed to identify the factors associated with SI and to build prediction models in Korean adults using machine learning methods. MethodsThe 2010–2013 dataset of the Korea National Health and Nutritional Examination Survey was used as the training dataset (n=16,437), and the subset collected in 2015 was used as the testing dataset (n=3,788). Various machine learning algorithms were applied and compared to the conventional logistic regression (LR)-based model. ResultsCommon risk factors for SI included stress awareness, experience of continuous depressive mood, EQ-5D score, depressive disorder, household income, educational status, alcohol abuse, and unmet medical service needs. The prediction performances of the machine learning models, as measured by the area under receiver-operating curve, ranged from 0.794 to 0.877, some of which were better than that of the conventional LR model (0.867). The Bayesian network, LogitBoost with LR, and ANN models outperformed the conventional LR model. ConclusionA machine learning-based approach could provide better SI prediction performance compared to a conventional LR-based model. These may help primary care physicians to identify patients at risk of SI and will facilitate the early prevention of suicide.

Cognition, The Menstrual Cycle, and Premenstrual Disorders: A Review.

Sex hormones, such as estrogens, progesterone, and testosterone, have a significant influence on brain, behavior, and cognitive functioning. The menstrual cycle has been a convenient model to examine how subtle fluctuations of these hormones can relate to emotional and cognitive functioning. The aim of the current paper is to provide a narrative review of studies investigating cognitive functioning in association with the menstrual cycle in biological females, with a focus on studies that have investigated cognitive functioning across the menstrual cycle in females with premenstrual mood disorders, such as premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). In line with previous reviews, the current review concluded that there is a lack of consistent findings regarding cognitive functioning across the menstrual cycle. Most studies focused on changes in levels of blood estrogen, and neglected to explore the role of other hormones, such as progesterone, on cognitive functioning. Cognitive research involving premenstrual disorders is in its infancy, and it remains unclear whether any cognitive disturbances that are identified may be attributed to negative experience of mood and psychological symptoms or be a more direct effect of hormonal dysregulation or sensitivity. Suggestions for future research are provided.

The similar past pain experience evokes both observational contagious pain and consolation in stranger rat observers

Laboratory rodents have been shown to have an ability to recognize the injury site and negative emotional state of their conspecifics in pain, resulting in empathic consoling behaviors and observational contagious pain (OCP). However, these empathic responses have been shown to be familiarity-dependent. In this report, we further explored whether the past pain experience could evoke empathic response in stranger observers. In our rodent model, two types of empathic response have been identified from naive cagemate observer (COnaive) during and after a priming dyadic social interaction (PDSI) with a cagemate demonstrator in pain (CDpain): the consolation and OCP. Consolation is represented by allolicking and allogrooming behaviors toward the CDpain, while the OCP is represented by a long-term mechanical pain hypersensitivity. The current results showed that: (1) neither the consolation nor OCP could be identified in the naive noncagemate observer (NCOnaive) during and after a PDSI with a noncagemate demonstrator in pain (NCDpain); (2) nor were the two types of empathic response seen in the NCO, who had just experienced acute pain (NCOpainexp), during and after a PDSI with a naive unfamiliar conspecific (NCDnaive). However, both the consolation and OCP were dramatically identified in the NCOpainexp during and after a PDSI with a NCD in pain (NCDpain). The current results demonstrated that the past pain experience can evoke both consolation and OCP in stranger rat observers when witnessing a conspecific in pain, implicating that the processing of empathy for pain can be modulated by past negative mood experience.

The structure of mania: An overview of factorial analysis studies.

Operational definitions of mania are based on expert consensus rather than empirical data. The aim of this study is to identify the key domains of mania, as well as the relevance of the different signs and symptoms of this clinical construct. A review of latent factor models studies in manic patients was performed. Before extraction, a harmonization of signs and symptoms of mania and depression was performed in order to reduce the variability between individual studies. We identified 12 studies fulfilling the inclusion criteria and comprising 3039 subjects. Hyperactivity was the clinical item that most likely appeared in the first factor, usually covariating with other core features of mania, such as increased speech, thought disorder, and elevated mood. Depressive-anxious features and irritability-aggressive behavior constituted two other salient dimensions of mania. Altered sleep was frequently an isolated factor, while psychosis appeared related to grandiosity, lack of insight and poor judgment. Our results confirm the multidimensional nature of mania. Hyperactivity, increased speech, and thought disorder appear as core features of the clinical construct. The mood experience could be heterogeneous, depending on the co-occurrence of euphoric (elevated mood) and dysphoric (irritability and depressive mood) emotions of varying intensity. Results are also discussed regarding their relationship with other constitutive elements of bipolar disorder, such as mixed and depressive states.

Everyday Aesthetics in the Dialogue of Chinese and Western Aesthetic Sensibilities

The paper examines the intercultural dimension of everyday aesthetics which was promoted by one of its most important Chinese proponents Liu Yuedi as a search for dialogue between various aesthetic traditions, in particular, those from the East and West. The aim of the paper is to explore some parallels between the traditional Chinese and contemporary Western aesthetic sensibilities, by looking for their common values and concepts which are gaining prominence in the discourse of everyday aesthetics. It begins with a survey of the contributions of Chinese and Western scholars; the survey concerns the relevance of Chinese (Confucian and Daoist) traditional aesthetics for everyday aesthetics, and examines particular features of the nature of perception in everyday aesthetics which is common to Chinese and Western artistic activities, aesthetic discourses and their conceptualizations. In the second section I discuss the “intercultural” concept of atmosphere as the de-personalized or “transpersonal”/intersubjective, vague and all-inclusive experience of the situational mood and environmental wholeness. I explore and compare the reflection of its characteristics in Western scholarship and Chinese aesthetics, especially in regard to the aural perception and sonic sensibility. The final section provides a comparative analysis of few examples of the integration of music into the environmental or everyday surrounding—in Daoist philosophy and Chinese everyday aesthetics, and Western avant-garde art (precisely, musical composition by John Cage 4’33). The analysis is concentrated on the perception of music in relation to the experience of atmosphere and everyday aesthetics, as they were defined in the previous sections. The paper challenges the “newness” of everyday aesthetics, especially if it is viewed from the intercultural perspective, and proposes the separation of its discourses into the investigation of its past and present.

Supplemental Material for Automatic Partner Attitudes and Daily Experiences of Mood and Relationship Satisfaction

Future expectations in clinical depression: Biased or realistic?

Negative expectations have been highlighted as a key mechanism in the maintenance and recurrence of depression. Nonetheless, no study has investigated currently depressed individuals' expectations about their future mood so far. This is surprising given that experiences of sustained negative mood and lack of positive mood are the hallmark symptoms of depression. The present study thus assessed depressed individuals' expectations about their future mood and examined whether these expectations are accurate or negatively biased. The study used experience sampling methodology (ESM) to contrast participants' expectations with their actually experienced sad and happy mood within a 4-day period. At the end of this period, participants recalled their past mood. All variables were assessed in 30 clinically depressed individuals and 37 matched healthy controls, as well as in 56 undergraduate students with a wide range in depressive symptoms. Results revealed that clinically depressed individuals held negatively biased expectations about their future mood: they expected more sad and less happy mood than they actually experienced. In contrast, healthy individuals showed realistic expectations about their future mood. Depressed individuals also demonstrated a negative mood recall bias. Finally, individuals' expectations and memories were more closely linked to depression status than their actually experienced mood. Although negative mood is the hallmark symptom of depression, the expectations and memories of negative mood may be even more central for the understanding of depression.

Self-harm prevalence and ideation in a community sample of cis, trans and other youth

Background: Trans youth have been reported to have high rates of self-harm, depression and bullying, and find it difficult to seek support. However, much of this research comes from gender identity clinics; non-clinical samples and those who reject gender binaries remain under-researched.Aims: This study investigated the experiences of a community school-based sample of Trans, identifying youth, Other, and cis-gendered adolescents in relation to their experiences of low mood, bullying, associated support, self-harm ideation and peer-related self-harm.Methods: An online survey was completed by 8440 13–17 year olds (3625 male, 4361 female, 227 Other, and 55 Trans).Results: Trans and Other students had significantly higher rates of self-harm ideation and peer self-harm, in comparison to cis-gendered students. These Trans and Other students reported significantly higher rates of bullying and self-reported depression and significantly less support from teachers and staff at school, in fact these students did not know where to go to access help.Discussion: This community sample confirms findings of high rates of self-harm ideation, self-reported depression and bullying for Trans youth as previously reported in clinic-based samples. However, by accessing a community sample, the salience of the category “Other” was established for young people today. While Other and Trans identified students both struggled to find support, those who identified as Trans were more likely to have been bullied, and have experienced self-reported depression and thoughts of self-harm. Thus, those who identify as transgender represent a high-risk group that needs targeted support within schools and by statutory and nonstatutory community services. Unpacking the category of Other would be beneficial for future research, as well as exploring resilience within this group and intersecting identities such as sexuality, Autism, or experiences such as earlier abuse.

Experiences of Low Mood in Young People With Cancer: A Qualitative Study.

Young people with cancer are at increased risk of psychological difficulty; yet there is little research on their experiences of low mood or depressive symptoms to help inform treatment interventions. This qualitative study explored experiences and opinions of low mood or depression in young people with cancer, how their mood related to developmental challenges, strategies used to cope, and how services could improve support. Nineteen young people diagnosed and treated for cancer completed semistructured interviews. Transcripts were thematically analyzed using the framework approach, and analysis produced eight themes, organized into three domains: "A Harder Time of Life," "Interpersonal Impact of Cancer," and "Learning to Understand and Describe Low Mood," Participants interviewed experienced low mood during cancer and predominantly felt "low mood" was a helpful term to describe their emotions. There were similarities and variations in their reported mood compared with clinical depression. The developmental challenges of being a young person with cancer negatively affected their mood. Participants used a variety of different coping strategies to manage these challenges. Young people were clear that they would like others to help them understand negative emotions experienced through cancer are normal to feel and support for low mood to be accessible and available.

(159) An Exploratory Ethnographic Study on Pain Descriptor Usage among African Americans and non-Hispanic Whites in the Nashville Area

This poster will present findings from an exploratory, ethnographic study examining descriptors of pain used by African Americans and non-Hispanic Whites in the Nashville area. Pain is a universal phenomenon. But despite its pervasiveness as an experience, the ability to adequately communicate how pain feels frequently eludes people. The inability to articulate the characteristics of pain can have clinical implications, from misdiagnoses to distrust on behalf of the health care provider, and a sense of frustration on part of the patient seeking treatment. Further, potential linguistic differences may amplify this inability to communicate the experience of pain across socio-economic and ethnic lines. The McGill Pain Questionnaire (MPQ) is currently the most widely used and respected subjective scale for rating pain. The instrument asks respondents to rate their pain along two dimensions: a sensory dimension, related to what the patient “feels” (i.e. stabbing, burning, aching, etc.), and an affective dimension, which explores the mood and cognitive experience of pain (i.e. punishing, exhausting, worrying, etc.). The aim of this study is to examine if there are ethnic differences between how Non-Hispanic Whites and African Americans in the Nashville area think of, and ultimately speak about their experiences with pain. Rather than assuming that people conceptualize and describe pain using terms and domains included in the MPQ scale, this project will seek to elicit the terms and dimensions individuals use to describe pain experiences in their own words. Clinical implications for the assessment and diagnosis of pain related conditions are discussed. (Melzak and Katz, 2013).

Emotion Regulation and the Experience of Future Negative Mood: The Importance of Assessing Social Support.

Emotion regulation refers to the use of various strategies, such as cognitive reappraisal and expressive suppression, to help manage our negative experiences, emotions, and thoughts. Although such emotion regulation often occurs within broader social dynamics and interactions, little is known about how social contexts interact with specific regulation strategies to shape the experience of negative emotions. Using data from 544 young adult university students, we provide initial evidence that habitual use of cognitive reappraisal is associated with lower future experience of depression and anxiety primarily through higher perceived social support (PSS). In contrast, expressive suppression is associated with higher future depression and anxiety primarily through lower PSS. These patterns are consistent with the importance of interpersonal influences on emotion regulation and suggest that assessment of social support can help elucidate the mechanisms of successfully regulating negative mood.

Depression disorder in patients with cerebellar damage: Awareness of the mood state.

BackgroundAlthough depressive symptoms are often reported to be comorbid with degenerative cerebellar diseases, the role of the cerebellum in depressive disorder needs to be elucidated. To address this aim, we investigated self-perception of the negative mood state in patients with cerebellar pathology and depressive symptoms. MethodsThirty-eight patients with cerebellar damage (10 with depressive symptoms – CB-DP and 28 with no depressive symptoms – CB-nDP), 11 subjects with depressive disorders without cerebellar damage (DP) and 29 healthy controls (CTs) were enrolled. A device for self-monitoring of the mood state (MoMo) and validated scales such as the Profile of Mood States questionnaire (POMS), the Self-Report Symptom Inventory-Revised (SCL-90-R) and the Hamilton Depression Rating Scale (HDRS) were used to evaluate depressive symptoms. ResultsBoth CB-DP and DP patients showed higher scores than CTs on the POMS and SCL-90-R for depressive factors and on the HDRS. DP patients showed a lower frequency of ‘good’ mood and a higher frequency of ‘bad’ mood than CTs when using the MoMo device. However, although the two depressed populations showed comparable scores on these validated scales, CB-DP patients showed impaired self-awareness of the mood experience in ‘the here and now’, as evidenced by the absence of significant differences, compared with CTs, in the subjective mood evaluation performed with the MoMo device. LimitationsThe number of CB patients and inhomogeneity across MRI scans were study limitations. ConclusionCerebellar dysfunction might slow the data integration necessary for mood state awareness, resulting in difficulty of depressed CB patients in explicitly recognizing their mood “in the here and now”.
