A thesis is an aptitude test for students. The approval of the thesis is proof that the student has sufficient research and reporting skills to graduate but does not guarantee the quality of the research and the results of the research as such, and the thesis is therefore not necessarily suitable to be used as an academic source to refer to. If you would like to know more about the research discussed in this thesis and any publications based on it, to which you could refer, please contact the supervisor mentioned.
Abstract
This paper aims to explain previous studies’ findings investigating letter recognition accuracies for words and non-words based on the conceptual network of De Vries (2016). Past studies, predicted a hook-shaped pattern of letter recall accuracies in non-words, however, an unexpected peek at the third letter occurred. Another set of studies attempted to explain the peak by utilizing warning signals. The researchers hypothesized that a centered warning signal was expected to produce a peak in letter recall accuracy for nonwords, however, the results were not significant for German words and non-words. To explain the results of past studies, the current paper will account for head frequency, a variable that was not accounted for in past research. The current study will control for the head frequency of non-words, using only high head frequency English non-words. It is hypothesized that if participants will be presented with exclusively high-frequency nonwords, the results of this study will be similar to those of previous studies which used German words and nonwords, meaning that the distribution of accuracies will be hook-shaped. Moreover, the participants will be presented with centered and distributed warning signals, however, no effect of warning signals over letter recall accuracy is expected since only high-frequency nonwords will be used. To test for these hypotheses, an online letter recognition task following a 2x2x5 design was conducted (N= 45). The results of this study found support for the expected hook shape pattern
