Megastudies are one of the tools which researchers in psychology and linguistics use when investigating various language phenomena. This study presents an analysis of the association between word length, subjective frequency, concreteness and age of acquisition ratings, and reaction times in a visual lexical decision task. Using a megastudy paradigm, we have collected data on 2614 Croatian nouns, from a total of 92 participants. The results of the analyses conducted on the dataset mostly confirm the findings of previous research — shorter lexical decision times are associated with more frequent words, shorter words, and words acquired earlier in life. Findings on the association between lexical decision times and word concreteness are mixed. Both reaction-level and aggregate data related to the study have been made freely available to the public. The datasets contain lexical and subjective word frequency estimates, word lengths, animacy and gender, as well as word concreteness, imageability and age of acquisition ratings.
