Exploring word recognition with selected stimuli: The case for decorrelated parameters


We report a study of naming and lexical decision with 132 adult Greek speakers responding to 150 words and matched pseudowords with decorrelated frequency, length, neighborhood, syllable and bigram frequency, and transparency. This approach allowed us to individuate and accurately estimate the effects of each variable, and to assess their linearity and additivity. Significant effects of frequency, length, and syllable frequency were revealed, as well as several interactions. The results are informative for cognitive modeling of visual word recognition in more transparent orthographies.
