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. Using VR technology in neuropsychological evaluation offers several benefits, but most importantly it can be used to display dynamic types of stimuli in a 3D environment in a controlled manner which is more representative of the real world. Moreover, it offers highly accurate measures (e.g., eye movements and sensor data) to characterize patient’s defects with high precision in an experimentally controlled setting that is not possible using conventional methods.

Virtual reality environment to assess and support social gaze in children on the autism spectrum (VirtualGaze)
Children on the autism spectrum have challenges in reciprocal social interaction, such as eye-contact and following other people’s gaze direction. In this project, we design a virtual reality (VR) assessment and intervention protocol for social gaze using a participatory approach. We assess social gaze in children on the autism spectrum and typically developing children using multilevel data (eye-tracking, physiological, neural and behavioural) and carry out a VR intervention to support contextually relevant use of gaze. The research is conducted at the Research Unit of Logopedics in multidisciplinary collaboration with researchers and Peili Vision Oy. The development of novel research-based assessment methods provides information necessary for understanding children’s social gaze in a sensitive way. The project increases the knowledge on benefits of digitalization by studying VR as an ecological bridge for children to practise different processes of social gaze.

Virtual real (VIRE): assesment and intervention of speech comprehension in school-aged children with and without language deficits
Difficulties in understanding spoken language are at the core of neurodevelopmental disorders such as autism spectrum disorders and developmental language disorders. Speech comprehension deficits may negatively affect social-emotional development, mental health and academic performance. There is a need to develop novel assessment and intervention methods to target and support treatment. Virtual reality (VR) can be used as an ecologically valid platform for conducting language research and studying speech comprehension.

Immersive Virtual Reality in Aphasia Telerehabilitation
In Finland, the lack of adequate resources associated with an aphasia rehabilitation is a challenge, and there is a need to solve this issue. The purpose of this study is to investigate the use of an immersive virtual reality (VR) in a telerehabilitation and for the people with aphasia (PWA). In this study, the PWA will be practicing at their home with support by their relatives, and participants will also receive regular remote guidance by a speech and language therapist during the intervention. This model of rehabilitation has been already studied at the University of Oulu in the form of preliminary pilot study and with encouraging results by the Research Unit of Logopedics and the Peili Vision Oy.
