Virtual Reality-Based Assessment of Executive Functions
The assessment of executive functions (EFs) is a central part of any neuropsychological evaluation, since deficits of EF are common among children. For example, a vast majority of the incoming patients at the Helsinki University Hospital’s Child psychiatric units are reported as having EF problems. These deficits should be reliably and objectively evaluated in order to ensure effective treatment that targets the core difficulties of the child.

Virtual Reality-Based Assessment of Neglect
Neglect is a common symptom after stroke. It is characterized by a failure to orient, report, or respond to stimuli located on the opposite side of the brain lesion. Its adverse impact on daily functioning and recovery from stroke is well established. Paper-and-pencil tests are traditionally used to assess the presence of neglect symptoms in a clinical setting, even though a large body of research has shown that their sensitivity is variable and too imprecise to detect for example subtle or chronic forms of neglect. Virtual reality (VR) technology offers various opportunities to improve assessment of neglect symptoms in different time points after stroke.

Virtual reality environment in digital examination of social gaze and social language comprehension in atypically developing children
Virtual reality environment (VRE) is an interactive, three-dimensional environment created by computer modelling (Lowood, 2015). VRE is used increasingly to study populations with communication disorders (Parsons et al., 2017, Mesa Gresa et al., 2018). In this study we investigate social gaze and language comprehension by children with autism spectrum disorder (ASD) and developmental language disorder (DLD) using digital VRE online tracking. We will examine whether VRE gaming intervention improves social gaze and language comprehension skills and how practice in virtual environment generalizes to social interactions in everyday life. Using machine learning based digital methods, we assess children’s social communication from real-life videos before and after the intervention.
