Abstract
The present paper builds on previous studies investigating letter recognition based on the conceptual network (CN) and serial binding. The predicted pattern of previous studies was a hook shaped decay effect for non-word stimuli, but found an unexpected peak in the third letter position instead. The present study aims to explain this peak by manipulating frequency heads in words and nonwords, as well as a centered warning signal, predicting different letter recall accuracies for different conditions. The current study did not find support for the effect of the centered warning signal on these variables but did find support for the effect of head frequency on the peak effect and letter recall accuracy due to relatively high presence of high frequency words in previous studies. Future studies should focus on both head and tail frequencies of words, as well as further investigate the hook shape of the letter decay effect. Keywords: Letter recall, Word recognition, Conceptual Network, Structural Models, Head Frequency
