Sensory Processing of Time and Space in Autistic Children
Background/Objectives : Autism is characterized by atypical sensory processing, which affects spatial and temporal perception. Here, we explore sensory processing in children with autism, focusing on visuospatial and temporal tasks across visual and auditory modalities. Methods : Ninety-two children aged 4 to 6 participated, divided into three groups: autism ( n = 32), neurotypical chronological age-matched controls ( n = 28), and neurotypical de…
A Comparative Study of Short-Term Social Media Use with Face-to-Face Interaction in Adolescence
The absence of cognitive effects may be explained by excessive screen time as a key factor in cognitive impact and by the cultural integration of social media, creating a "ceiling effect" that minimizes the impact of short-term exposure and resembles addictive behavior. These findings emphasize the importance of a holistic approach involving families, schools, and governments to address both acute and cumulative social media use in adolescents
Nomophobia and Its Predictors
Nomophobia, or the fear of not being able to use a smartphone and/or the services, has gained increasing attention due to its growing prevalence. This study aimed to examine the prevalence of nomophobia and of potential variables associated with the phenomenon. Additionally, it sought to determine if the average of total nomophobia and the four second-order factors differed across gender. Finally, it analyzed the associations between nomophobia (…

However, Facebook intrusion or addiction is a growing concern as it involves an excessive attachment to Facebook, which disrupts daily functioning. To date, few studies have examined whether cross‐cultural differences in the measurement of Facebook addiction exist. The aim of this study was to investigate the cross‐cultural validity and measurement invariance of the Facebook Intrusion Q…

However, the impact of the constant use of information and communication technologies on the mental health of workers needs to be considered. We aimed to investigate the impact of different work conditions on mental health, to which end we disseminated an online questionnaire during lockdowns to assess imagine…

The Phubbing Scale (PS-8) in the Portuguese population
Phubbing is defined as ignoring other individuals by using a mobile phone during a face-to-face conversation. The Phubbing Scale (PS) was developed to assess this practice. In this study, we analyze the psychometric properties of the 8-item version of the PS (PS-8) in the Portuguese population, providing validity evidence based on internal structure and on relationships with other variables, and examining item properties, reliability, and measure…

Mobile phone addiction is a robust phenomenon observed throughout the world. The social aspect of mobile phone use is crucial; therefore, phubbing is a part of the mobile phone addiction phenomenon. Phubbing is defined as ignoring an interlocutor by glancing at one's mobile phone during a face‐to‐face conversation. The main aim of this study was to investigate how the Phubbing Scale (containing 10 items) might vary across countries, and between g…
Mapping of serological testing and Sars-CoV-2 seroprevalence studies performed in 20 European countries, March-June 2020

While robust SARS-CoV-2 serological assays were quickly developed, only limited information on applied serological testing is available. We describe the extent and nature of SARS-CoV-2 serological testing used in Europe and assess the links between epidemiology, mitigation strategies applied and seroprevalence. METHODS: An online questionnaire on SARS-CoV-2 serology was …
