Habituation Phase

Examination of habituation to disgust-related stimuli has received limited experimental investigation. In this study, 38 undergraduates were divided into two groups. The vomit-blood (VB) group was first exposed to a realistic approximation of vomit and allowed to habituate to this stimulus, while the blood-vomit (BV) group was first allowed to habituate to a realistic approximation of blood. Following the habituation phase, each group underwent a short exposure to the unexposed stimuli (blood in the VB group, vomit in the BV group). Physiological and self-report assessments were collected during exposure. Self-report habituation was observed for both groups. In addition, only muscle tension at the levator labii and heart rate in the VB group demonstrated significant changes that could be interpreted as habituation. Consistent with previous literature, muscle tension at the levator labii appeared to be a unique indicator of disgust responding. Implications and suggestions for future research are discussed.

Vagally mediated heart rate variability (HRV) is a psychophysiological indicator of mental and physical health. Limited research suggests there is reduced vagal activity and resulting lower HRV in patients with Major Depressive Disorder (MDD); however little is actually known about the association between HRV and symptoms of depression and whether the association mirrors symptom improvement following psychotherapy. The aim of this study was to investigate the association between antidepressant therapy, symptom change and HRV in 50 inpatients (68% females; 17–68 years) with a diagnosis of MDD. Severity of depressive symptoms was assessed by self-report (Beck Depression Inventory II) and the Hamilton Rating Scale of Depression. Measures of vagally mediated HRV (root mean square of successive differences and high-frequency) were assessed at multiple measurement points before and after inpatient psychotherapeutic and psychiatric treatment. Results showed an expected negative correlation between HRV and depressive symptoms at intake. Depressive symptoms improved (d = 0.84) without corresponding change in HRV, demonstrating a de-coupling between this psychophysiological indicator and symptom severity. To our knowledge, this study is the first to examine an association between HRV and depressive symptoms before and after psychotherapy. The observed de-coupling of depression and HRV, and its methodological implications for future research are discussed.

And Gender

Family caregivers of persons with bipolar disorder experience considerable stress. Yet, studies have not examined whether their stress differs by race and gender. This preliminary analysis of baseline data from 228 African American and White family caregivers of adults with bipolar disorder who were enrolled in a randomized controlled trial examined race and gender differences on two validated self-report measures of psychological stress (caregiver burden and caregiver reactions) and an electrocardiography device used to capture heart rate variability (HRV). No statistically significant differences were found by race or gender on either measure of psychological stress. African American caregivers had significantly lower scores on two indices of HRV compared to White caregivers. Women had significantly lower scores on one index of HRV compared to men. Low HRV indicates greater stress and mortality risk. Future research should include HRV to measure caregiver stress and implement relevant interventions.

Self Harm

Background: Identifying risk factors for suicide-related thoughts and behaviors (SRTB) is essential among adolescents in whom SRTB remain a leading cause of death. Although many risk factors have already been identified, influential theories now suggest that the domain of interpersonal relationships may play a critical role in the emergence of SRTB. Because attachment has long been seen as the foundation of interpersonal functioning, we suggest that attachment insecurity warrants attention as a risk factor for SRTB. Aims: This study sought to explore relations between attachment organization and suicidal ideation, suicide attempts, and self-harm in an inpatient adolescent sample, controlling for demographic and psychopathological covariates. Method: We recruited 194 adolescents from an inpatient unit and assigned them to one of four attachment groups (secure, preoccupied, dismissing, or disorganized attachment). Interview and self-report measures were used to create four variables reflecting the presence or absence of suicidal ideation in the last year, single lifetime suicide attempt, multiple lifetime suicide attempts, and lifetime self-harm. Results: Chi-square and regression analyses did not reveal significant relations between attachment organization and SRTB, although findings did confirm previously established relations between psychopathology and SRTB, such that internalizing disorder was associated with increased self-harm, suicide ideation, and suicide attempt and externalizing disorder was associated with increased self-harm. Conclusion: The severity of this sample and methodological differences from previous studies may explain the nonsignificant findings. Nonsignificant findings may indicate that the relation between attachment organization and SRTB is moderated by other factors that should be explored in future research.

Abstract. Ambulatory assessment methods are well suited to examine how patients with panic disorder and agoraphobia (PD/A) undertake situational exposure. But under complex field conditions of a complex treatment protocol, the variability of data can be so high that conventional analytic approaches based on group averages inadequately describe individual variability. To understand how fear responses change throughout exposure, we aimed to demonstrate the incremental value of sorting HR responses (an index of fear) prior to applying averaging procedures. As part of their panic treatment, 85 patients with PD/A completed a total of 233 bus exposure exercises. Heart rate (HR), global positioning system (GPS) location, and self-report data were collected. Patients were randomized to one of two active treatment conditions (standard exposure or fear-augmented exposure) and completed multiple exposures in four consecutive exposure sessions. We used latent class cluster analysis (CA) to cluster heart rate (HR) responses collected at the start of bus exposure exercises (5 min long, centered on bus boarding). Intra-individual patterns of assignment across exposure repetitions were examined to explore the relative influence of individual and situational factors on HR responses. The association between response types and panic disorder symptoms was determined by examining how clusters were related to self-reported anxiety, concordance between HR and self-report measures, and bodily symptom tolerance. These analyses were contrasted with a conventional analysis based on averages across experimental conditions. HR responses were sorted according to form and level criteria and yielded nine clusters, seven of which were interpretable. Cluster assignment was not stable across sessions or treatment condition. Clusters characterized by a low absolute HR level that slowly decayed corresponded with low self-reported anxiety and greater self-rated tolerance of bodily symptoms. Inconsistent individual factors influenced HR responses less than situational factors. Applying clustering can help to extend the conventional analysis of highly variable data collected in the field. We discuss the merits of this approach and reasons for the non-stereotypical pattern of cluster assignment across exposures.

A mixed-design experiment was conducted to explore differences between searching and surfing on cognitive and emotional responses to online news. Ninety-two participants read three unpleasant news stories from a website. Half of the participants acquired their stories by searching, meaning they had a previous information need in mind. The other half of the participants acquired their stories by surfing, with no previous information need in mind. Heart rate, skin conductance, and corrugator activation were collected as measures of resource allocation, motivational activation, and unpleasantness, respectively, while participants read each story. Self-report valence and recognition accuracy were also measured. Stories acquired by searching elicited greater heart rate acceleration, skin conductance level, and corrugator activation during reading. These stories were rated as more unpleasant, and their details were recognized more accurately than similar stories that were acquired by surfing. Implications of these results for understanding how people process online media are discussed.

The limitations of self-report techniques (i.e., questionnaires or surveys) in measuring consumer response to advertising stimuli have necessitated more objective and accurate tools from the fields of neuroscience and psychology for the study of consumer behavior, resulting in the creation of consumer neuroscience. This recent marketing sub-field stems from a wide range of disciplines and applies multiple types of techniques to diverse advertising subdomains (e.g., advertising constructs, media elements, or prediction strategies). Due to its complex nature and continuous growth, this area of research calls for a clear understanding of its evolution, current scope, and potential domains in the field of advertising. Thus, this current research is among the first to apply a bibliometric approach to clarify the main research streams analyzing advertising persuasion using neuroimaging. Particularly, this paper combines a comprehensive review with performance analysis tools of 203 papers published between 1986 and 2019 in outlets indexed by the ISI Web of Science database. Our findings describe the research tools, journals, and themes that are worth considering in future research. The current study also provides an agenda for future research and therefore constitutes a starting point for advertising academics and professionals intending to use neuroimaging techniques.

The Impact

Objective: To provide an overview of what is known about the impact of COVID-19 on weight and weight-related behaviors. Methods: Systematic scoping review using the Arksey and O’Malley methodology. Results: A total of 19 out of 396 articles were included. All studies were conducted using online self-report surveys. The average age of respondents ranged from 19 to 47 years old, comprised of more females. Almost one-half and one-fifth of the respondents gained and lost weight during the COVID-19 pandemic, respectively. Among articles that examined weight, diet and physical activity changes concurrently, weight gain was reported alongside a 36.3% to 59.6% increase in total food consumption and a 67.4% to 61.4% decrease in physical activities. Weight gain predictors included female sex, middle-age, increased appetite, snacking after dinner, less physical exercise, sedentary behaviors of ≥6 h/day, low water consumption and less sleep at night. Included articles did not illustrate significant associations between alcohol consumption, screen time, education, place of living and employment status, although sedentary behaviors, including screen time, did increase significantly. Conclusions: Examining behavioral differences alone is insufficient in predicting weight status. Future research could examine differences in personality and coping mechanisms to design more personalized and effective weight management interventions.

Electrocardiogram Monitoring

During the pregnancy, fetal electrocardiogram (FECG) is deployed to analyze fetal heart rate (FHR) of the fetus to indicate the growth and health of the fetus to determine any abnormalities and prevent diseases. The fetal electrocardiogram monitoring can be carried out either invasively by placing the electrodes on the scalp of the fetus, involving the skin penetration and the risk of infection, or non-invasively by recording the fetal heart rate signal from the mother’s abdomen through a placement of electrodes deploying portable, wearable devices. Non-invasive fetal electrocardiogram (NIFECG) is an evolving technology in fetal surveillance because of the comfort to the pregnant women and being achieved remotely, specifically in the unprecedented circumstances such as pandemic or COVID-19. Textiles have been at the heart of human technological progress for thousands of years, with textile developments closely tied to key inventions that have shaped societies. The relatively recent invention of smart textiles is set to push boundaries again and has already opened the potential for garments relevant to medicine, and health monitoring. This paper aims to discuss the different technologies and methods used in non-invasive fetal electrocardiogram (NIFECG) monitoring as well as the potential and future research directions of NIFECG in the smart textiles area.

Perception Of Threat

In the first few months of the pandemic, Makkah region reported the highest number of COVID-19 cases among all regions in Saudi Arabia. More than 80% of these reported cases were non-Saudi residents. In this study, we evaluated the perceived threat from and psychological impact of COVID-19 among non-Saudi residents of Makkah region. This was a cross-sectional analysis of data collected using a standardized self-report questionnaire. A total of 292 expatriates were included in the study, the majority of whom were non-Arabic speakers. The prevalence of self-reported depression was nearly 40%, anxiety was 32%, and stress was 43%. The findings indicated variability in the prevalence of psychological symptoms among expatriates from different ethnic backgrounds. Additionally, work environment and perceived threat were strong predictors of psychological disorders. This suggested that the perceived threat from and psychological burden of COVID-19 among non-Saudis in Makkah region is substantial. Future research should investigate the reasons behind these variations in the psychological impact of the pandemic among different ethnic groups.
