Erik Seesjärvi, Clinical Psychologist (M. A.) specializing in neuropsychology, University of Helsinki: Virtual Reality-Based Assessment of Executive Functions
The assessment of executive functions (EFs) is a central part of any neuropsychological evaluation. However, EFs are one of the most difficult cognitive domains to assess with the traditional paper-and-pencil -methods, since these tasks may fail to replicate the demands of the everyday situations, which are complex and full of distractions. By using Virtual Reality, we aim to develop a method that mimics the demands of everyday life while being psychometrically robust and reliable. [Read more]

A. Heinikoski, T. Parviainen, J. Auvinen & M. Lehtihalmes, Research Unit of Logopedics, University of Oulu: Using immersive virtual reality headset for treatment of word finding difficulties in aphasia therapy
New technology will provide many opportunities to provide highly personalized interventions for patients with various motor and cognitive disorders, e.g. aphasia. Teletherapy using true or virtual environments, avatars and virtual therapists has been shown as effective as face-to-face methods to provide therapeutic services for patients with aphasia (Marshall et al., 2018; Safro et al., 2018). In addition, these methods have been shown highly acceptable to clients (Amaya et al., 2018). Virtual reality has been a part of neurological rehabilitation for decays already. However, in vast majority of studies, 2-D or 3-D computer environments are used in motor or cognitive rehabilitation. In the present pilot study, we will compare traditional face-to-face picture naming exercises by the table and immersive context-based virtual environments using head-mounted display for treatment of word-finding difficulties in patients with aphasia.

Satu Paavola, Speech and Language Pathologist (M.A.) University of Helsinki: 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. [Read more]
