“…The materials for these tests are free for use in scientific research, and we used them for our own implementations of the test. The tests are listed under ‘Extra tests’ and ‘Extra tests production’, respectively, in the graphical user interface and measure the following psychological constructs: Linguistic experience (piloted in Flemish speakers; i.e., receptive vocabulary size , ‘Dutch Auditory & Image Vocabulary Test’, Bousard & Brysbaert, 2021 ; ‘Receptive vocabulary test (multiple choice)’, Vander Beken and Brysbaert, 2018 ), non-verbal reasoning (‘Matrix reasoning test’, Chierchia et al, 2019 ), personality traits (‘BIG 5 personality traits’, Denissen et al, 2020 ), word-reading (piloted in Flemish speakers; ‘One Minute Reading Test’, Callens et al, 2012 ), and story-reading (piloted in Flemish speakers; ‘Story Reading Test’, Rouweler et al, 2020 ). We included these tests as alternatives for copyright-protected tests we previously used to assess receptive vocabulary size and non-verbal reasoning.…”
