Wearable Long-Term Social Sensing for Mental Wellbeing

IEEE Sensors Journal (2018)

Jiang Long Bin Gao Jun Gu Yuanpeng Chen Zhao Gao

Long-term wellbeing monitoring is an underlying theme in many local and national policies and procedures outlined by governments and health care services. Natural, efficacious, and trustworthy monitoring by using wearable sensors is necessary for researchers to find and establish the interrelationships of affective computing, body sensor networks (BSNs), social signal processing, and physical mental health. Specially, Giancarlo Fortino has an outstanding contribution for applying BSNs on health monitoring. This paper investigated how technology can help to objectively monitor an individual's wellbeing in a naturalistic environment. For this purpose, we designed and implemented a wearable device with the integration of multi-sensors which consist of audio sensing, behavior monitoring, environment, and physiological sensing. In order to avoid privacy issues, four audio-wellbeing features are embedded into a wearable hardware platform to automatically evaluate speech information without preserving raw audio data. In addition, four weeks of long-term monitoring experiment studies have been conducted in conjunction with a series of wellbeing questionnaires in a group of students. The relationships between physical and mental health were investigated objectively by utilizing data from speech, behavioral activities and ambient factors in a completely natural daily situation.

Wearable Social Sensing and Its Application in Anxiety Assesment

Jun Gu Bin Gao Yuanpeng Chen Jiang Long Zhao Gao

It is meaningful to assess people's physical and mental health as well as the determination the sense of social behavior of using wearable equipment and analyze their voice and behavioral characteristics. Microphones, accelerometers and gyroscopes are embedded in wearable devices, which provides opportunities for non-invasive monitoring of anxiety and stress in real situation. In this paper, we devise a wearable platform that can be used to calculate and analyze social behavior signals. Experiment results shows that behavioral and linguistic features can show a variety of personal anxiety. This study has potential to objectively determine social behavior consciousness.

Oxytocin modulates the intrinsic dynamics between attention-related large scale networks

bioRxiv (Cold Spring Harbor Laboratory) (2018)

Fei Xin Feng Zhou Xinqi Zhou Xiaole Ma Yayuan Geng

Abstract Attention and salience processing have been linked to the intrinsic between- and within-network dynamics of large scale networks engaged in internal (default mode network, DN) and external attention allocation (dorsal attention, DAN, salience network, SN). The central oxytocin (OXT) system appears ideally organized to modulate widely distributed neural systems and to regulate the switch between internal attention and salient stimuli in the environment. The current randomized placebo (PLC) controlled between-subject pharmacological resting-state fMRI study in N = 187 (OXT, n = 94; n = 93; single-dose intranasal administration) healthy male and female participants employed an independent component analysis (ICA) approach to determine the modulatory effects of OXT on the within- and between-network dynamics of the DAN-SN-DN triple network system. OXT increased the functional integration between subsystems within SN and DN and increased functional segregation of the DN with the SN and DAN engaged in attentional control. Whereas no sex differences were observed, OXT effects on the DN-SN interaction were modulated by autism traits. Together, the findings suggest that OXT may facilitate efficient attentional allocation towards social cues by modulating the intrinsic functional dynamics between DN components engaged in social processing and large-scale networks involved in external attentional demands (SN, DAN).

Feng Zhou Guanghong Gong Peng Ding Wen Shi Xiaole Ma

According to the property of DEM, on the base of multi-resolution analysis algorithm this paper presents a method for multi-resolution modeling based on wavelet analysis. Then the paper analyzes the principles for choosing the fittest wavelet function and boundary extension mode. The paper also provide a way to choose the best resolution depended on the viewpoint and the viewing angle The paper suggests to control the threshold to build data pyramid. By some experiments, this method is proved to be efficient and robustness.

Oxytocin biases men but not women to restore social connections with individuals who socially exclude them

Scientific Reports (2017)

Xiaolei Xu Shuxia Yao Lei Xu Yayuan Geng Weihua Zhao

Abstract We normally react to individuals who exclude us socially by either avoiding them or increasing our attempts to interact with them. The neuropeptide oxytocin can promote social bonds and reduce social conflict and we therefore investigated whether it facilitates more positive social responses towards individuals who exclude or include us. In a double-blind, placebo-controlled, between-subject design 77 healthy Chinese male and female participants received intranasal oxytocin (40 IU) or placebo before playing a modified virtual ball-tossing game with three fictitious partners who either showed exclusion, inclusion or neutral behavioral interactions with them. Results showed that both male and female subjects threw the ball more often to individuals who excluded rather than included them, although oxytocin did not alter this or awareness/feelings of exclusion or inclusion. However, when subjects returned a week later males, but not females, in the oxytocin group exhibited an increased liking for, and preference for playing again with, players who had previously excluded them. This oxytocin effect was positively associated with independent traits. Our findings suggest that in a collectivist culture oxytocin may promote the desire of males, but not females, with a stronger independent orientation to rebuild social connections with individuals who have previously excluded them.

Common and Dissociable Contributions of Alexithymia and Autism to Domain-Specific Interoceptive Dysregulations: A Dimensional Neuroimaging Approach

Psychotherapy and Psychosomatics (2018)

Jia‐Lin Li Lei Xu Xiaoxiao Zheng Meina Fu Feng Zhou

Alexithymia represents a transdiagnostic marker across psychiatric entities associated with emotional impairments, including autism spectrum disorders (ASD). Accumulating evidence suggests that interoceptive dysfunctions that underpin the core symptomatic emotion recognition and empathy deficits in ASD may be contributed to by high levels of alexithymia rather than autistic symptoms per se. However, previous findings are hampered by generally elevated alexithymia in ASD patients, and thus were not able to differentiate common and distinct contributions across the entire spectrum of variations of autism and alexithymia. Moreover, the multi-factorial nature of the domains affected, such as distinct neural reactivity towards perceiving physical and affective pain, has not been accounted for. Against this background the present fMRI study employed a dimensional trait approach in n = 242 healthy subjects to determine common and distinct associations between both traits and pain empathic responses towards physical and affective pain. Higher levels of alexithymia associated with increased left anterior insula pain empathic reactivity. Disentangling these effects revealed a positive association during perceived physical pain, but a negative one during affective pain. No significant associations with trait autism were found, but an interaction effect between the trait dimensions was observed in the mid-cingulate cortex. Moderation analysis demonstrated that trait autism only impacted mid-cingulate reactivity towards physical pain in high alexithymia subjects, whereas reactivity towards affective pain was specifically associated with trait autism in low alexithymia subjects. Findings confirm previous patient studies suggesting that alexithymia rather than autism per se may drive altered insula pain empathic reactivity. Importantly, the present approach allowed for the first time to demonstrate that the impact of alexithymia on insula reactivity varies as a function of the pain empathic domain and that effects on other core empathy nodes evolve in interaction with trait autism.

Can pharmacological enhancement of the placebo effect be a novel therapy for working memory impairments?

bioRxiv (Cold Spring Harbor Laboratory) (2018)

Weihua Zhao Benjamin Becker Shuxia Yao Xiaole Ma Juan Kou

Abstract Working memory is considered as a core aspect of cognitive function and its impairment in a wide range of mental disorders has resulted in it being considered as an important transdiagnostic feature. To date pharmacological and behavioural strategies for augmenting working memory have achieved only moderate success. Here we have taken a different approach by combining expectancy effects with intranasal oxytocin as an adjunct given previous evidence that it may enhance placebo effects. In a randomised controlled clinical trial we demonstrate that while working memory performance is not influenced by expectancy per se when it is given in conjunction with oxytocin performance in terms of accuracy can be significantly enhanced following positive expectancy induction (placebo effect) and impaired following negative expectancy induction (nocebo effect). Thus combining expectancy effects with intranasal oxytocin may represent a radical new approach for improving working memory function in mental disorders.

Oxytocin Modulates the Intrinsic Dynamics Between Attention-Related Large-Scale Networks

Cerebral Cortex (2018)

Abstract Attention and salience processing have been linked to the intrinsic between- and within-network dynamics of large-scale networks engaged in internal (default network [DN]) and external attention allocation (dorsal attention network [DAN] and salience network [SN]). The central oxytocin (OXT) system appears ideally organized to modulate widely distributed neural systems and to regulate the switch between internal attention and salient stimuli in the environment. The current randomized placebo (PLC)-controlled between-subject pharmacological resting-state fMRI study in N = 187 (OXT, n = 94; PLC, n = 93; single-dose intranasal administration) healthy male and female participants employed an independent component analysis approach to determine the modulatory effects of OXT on the within- and between-network dynamics of the DAN–SN–DN triple network system. OXT increased the functional integration between subsystems within SN and DN and increased functional segregation of the DN with both attentional control networks (SN and DAN). Whereas no sex differences were observed, OXT effects on the DN–SN interaction were modulated by autistic traits. Together, the findings suggest that OXT may facilitate efficient attention allocation by modulating the intrinsic functional dynamics between DN components and large-scale networks involved in external attentional demands (SN and DAN).
