MEGALEX: A new mega-study of visual and auditory word recognition in French
International audience; We present a new mega-study (called MEGALEX) involving the collection of visual and auditory lexical decision data for 28,000 French words and the same number of pseudowords. This new mega-study applied the repeated measures design developed by Keuleers, Lacey, Rastle, and Brysbaert (2012). For each modality tested (visual vs. auditory), two groups of 40 participants each responded to 14,000 words and the same number of pseudowords for a total duration of 20h (divided over multiple sessions). Collected reaction times were submitted to multiple regression analyses in order to study the influence of continuous lexical variables such as word frequency, word length (in l…
Smart Phone, Smart Science: How the Use of Smartphones Can Revolutionize Research in Cognitive Science
WOS:000295936900019; International audience; Investigating human cognitive faculties such as language, attention, and memory most often relies on testing small and homogeneous groups of volunteers coming to research facilities where they are asked to participate in behavioral experiments. We show that this limitation and sampling bias can be overcome by using smartphone technology to collect data in cognitive science experiments from thousands of subjects from all over the world. This mass coordinated use of smartphones creates a novel and powerful scientific "instrument" that yields the data necessary to test universal theories of cognition. This increase in power represents a potential re…
