This would, in turn, allow the prime to exert its full influence, and thus produce more robust priming effects. The idea was that the speeded word fragment completion task requires more elaborate processing than do traditional paradigms such as lexical decision and naming. Heyman et al.’s main purpose was to develop a task that could successfully capture semantic priming effects. It is important to note that there was always only one correct completion, such that items like b_ll were never used. Heyman and colleagues used two variants of this task: one in which one of five vowels could be missing (i.e., a, e, u, i, or o), and one in which one of two vowels could be missing (i.e., a or e). Footnote 1 Participants are asked to complete each word fragment as quickly and accurately as possible by pressing a designated response key. Each trial in this task features a word from which one letter has been deleted (e.g., tom_to). In the present study we sought to build on this work, and we describe a megastudy involving the speeded word fragment completion task (Heyman, De Deyne, Hutchison, & Storms, 2015). ![]() This is a critical advantage of the megastudy approach, because artificially dichotomizing continuous variables has been shown to reduce power and increase the probability of Type I errors (Maxwell & Delaney, 1993). In addition, continuous variables such as word frequency need not be divided into distinct categories (i.e., high-frequency vs. The idea is that one can then statistically control for confounding variables by conducting a multiple regression analysis. Megastudies, on the other hand, aim to gather data for as many stimuli as possible, without many constraints. That is, factorial studies require one to experimentally control for a number of variables that could potentially obscure the effect(s) of interest. The rationale behind megastudies is that they complement (traditional) factorial studies in which stimuli are selected on the basis of specific lexical or semantic characteristics. Generally speaking, a typical megastudy comprises several thousand items for which lexical decision, naming, and/or word identification responses are collected. In the last decade, the field of visual word recognition has seen a surge in so-called megastudies (see Balota, Yap, Hutchison, & Cortese, 2012, for an overview). The article ends with a discussion of potential process models of the speeded word fragment completion task. We propose that both tasks are complementary when examining visual word recognition. Overall, the results revealed many similarities, but also some remarkable differences, which are discussed. Since all items were selected from the Dutch Lexicon Project (Keuleers, Diependaele, & Brysbaert Frontiers in Psychology, 1, 174, 2010), we ran the same analyses on lexical decision latencies to compare the two tasks. To this end, item-level regression and mixed-effects analyses were performed on the response latencies using 23 predictor variables. On the other hand, the aim was to gain insight into the underlying processes of the speeded word fragment completion task. ![]() On the one hand, it provides a rich database of over 8,000 stimuli, which can, for instance, be used in future research to equate stimuli on baseline response times. Given its potential, we conducted a study to gather speeded word fragment completion norms. That is, the speeded word fragment completion task is more efficient, more engaging, and easier. In addition, it has several advantages over the widely used lexical decision task. Previous work has shown that this paradigm can successfully capture subtle priming effects (Heyman, De Deyne, Hutchison, & Storms Behavior Research Methods, 47, 580–606, 2015). In the speeded word fragment completion task, participants have to complete fragments such as tom_to as quickly and accurately as possible.
