Internet gaming disorder (IGD) and problematic internet use (PIU) are becoming increasingly detrimental to modern society, with serious consequences for daily functioning. IGD PIU may be exacerbated by lifestyle changes imposed the coronavirus 2019 (COVID-19) pandemic. This study investigated in during pandemic risk factors them. is a part of larger online smartphone Japan, originally planned 2019, expanded August 2020 include impact COVID-19. 51,246 adults completed an survey (August 2020),...

When viewing a painting, artists perceive more information from the painting on basis of their experience and knowledge than art novices do. This difference can be reflected in eye scan paths during paintings. Distributions are different those even when paintings contain no figurative object (i.e. abstract paintings). There two possible explanations for this paths. One is that have high sensitivity to high-level features such as textures composition colors therefore fixations driven by...

Emotional contagion is a primitive form of empathy that does not need higher psychological functions. Recent studies reported emotional exists only between humans but also among various animal species. The dog (Canis familiaris) unique and the oldest domesticated Dogs have coexisted with for more than 30,000 years are woven into human society as partners bonding humans. acquired human-like communication skills and, likely result domestication process, ability to read emotions; therefore, it...

To develop a new generation advanced driver assistance system that avoids dangerous condition in advance, we need to predict driving behaviors. Since nonparametric Bayesian method with two-level structure successfully predicted the symbolized behaviors only, applied linear dynamical systems predicting behavior. The called beta process autoregressive hidden Markov model (BP-AR-HMM) segments into states each of which corresponds an AR and it predicts future using estimated state sequence...

Mistakes are valuable learning opportunities, yet in uncertain environments, whether a lack of reward is due to poor performance or bad luck can be hard tell. To investigate how humans address this issue, we developed visuomotor task where rewards depended on either skill chance. Participants consistently displayed self-attribution bias, crediting successes their own ability while blaming failures randomness, an effect that influenced subsequent decisions. Computational modelling revealed...

Abstract Background and aims Game genres, availability on smartphones, in-game purchases, playing duration, have been thought to influence Gaming Disorder (GD). However, little research has comprehensively examined their relationships with GD. Therefore, we the relationship between GD, gaming duration via consoles genres of smartphone games. Study 1 was based self-reports, 2 included objective data clarify these associations. Methods We conducted two independent online surveys that collected...

However, the mechanisms by individuals move cohesion are unknown. We applied novel non-invasive methods of drone filming and video tracking observe field high temporal spatial resolution. tracked all members drew trajectories. analyzed found two phases based on their...

With the spread of smartphones and computer games, concerns have escalated regarding rising prevalence gaming disorder. Patients often display attentional biases, unconsciously turning their attention towards gaming-related stimuli. However, attempts to discover ameliorate these deficits yielded inconsistent outcomes, potentially due dynamic nature bias. This study investigated neural mechanisms underlying bias state by combining neuroimaging (functional magnetic resonance imaging -fMRI)...

Graph neural networks (GNNs) have been widely used to learn vector representation of graph-structured data and achieved better task performance than conventional methods. The foundation GNNs is the message passing procedure, which propagates information in a node its neighbors. Since this procedure proceeds one step per layer, range propagation among nodes small lower layers, it expands toward higher layers. Therefore, GNN model has be deep enough capture global structural graph. On other...

Abstract The coronavirus disease 2019 (COVID-19) pandemic has profoundly affected the mental health of both infected and uninfected people. Although most psychiatric disorders have highly overlapping genetic pathogenic backgrounds, studies investigating impact examined only single disorders. It is necessary to examine longitudinal trajectories factors that modulate states across multiple dimensions. About 2274 Japanese citizens participated in online surveys presented December (before...

Expertise enables humans to achieve outstanding performance on domain-specific tasks, and programming is no exception. Many studies have shown that expert programmers exhibit remarkable differences from novices in behavioral performance, knowledge structure, selective attention. However, the underlying brain of are still unclear. We here address this issue by associating cortical representation source code with individual expertise using a data-driven decoding approach. This approach enabled...

Network data show the relationship among one kind of objects, such as social networks and hyperlinks on Web. Many statistical models have been proposed for analyzing these data. For modeling cluster structures networks, infinite relational model (IRM) was a Bayesian nonparametric extension stochastic block model. In this brief, we derive inference algorithms IRM network based variational (VB) methods. After showing standard VB inference, collapsed (CVB) its variant called zeroth-order CVB...

ABSTRACT Recent time-dependent analyses of stress-related disorders have identified heterogeneity trajectories and their modifying factors. While psychiatric patients are vulnerable to stress events, it is unclear how conditions in the general population modulate subsequent responses. Using our longitudinal online survey from before COVID-19 pandemic post-pandemic follow-ups (n = 3815 Japanese adults), here we four post-traumatic symptoms (PTSS) a latent growth mixture model; resilient,...

Search and rescue (SAR) dogs are widely used to locate victims at disaster sites. The efficiency of SAR missions can be greatly enhanced if a canine's emotional states, including their motivation search, remotely estimated in real time. In this study, we developed real-time emotion estimation system for canines based on measured electrocardiography signals. This proposed measures heartbeat intervals using specially canine suit equipped with an device. Using the online interval measurements,...
