Method in the madnessless: Exploring factors that impact the processing of two-suffixed complex words

<b>Dataset abstract</b> <p>The data collected includes lexical decision data and reaction time data from 56 participants. Three sets of 30 two-suffixed pseudowords were created, each based on a type of grammatical constraint attested in the literature, and presented along with 120 existing two-suffixed English words and 30 nonwords. The data aims to shed light on the as-yet understudied subject of the processing of two-suffixed complex words.</p>
