Abstract
The present study focused on the effect of high and low head frequency on letter recall (LR). Studies examining LR on the basis of the conceptual network model found an unexpected performance peak at the third letter position following an LR task. The current experiment examined the possibility of head frequency as an explanation of the unexpected finding. This experiment consisted of a Dutch LR task following a 2x2x5 design (N = 41) measuring response accuracy with two levels of word type: words and non-words, two levels of head frequency: high and low, and five different letter positions. Results supported the expected significant three-way interaction, but the finding of a u-shaped distribution did not support the hypothesised decay and reverberation effects for non-words. Additionally, we expected to find a performance peak at position three due to the centred warning signal, but no evidence was found to support this effect. Examining the graph we can deduce a significant effect of head frequency on the finding of the performance peak at position three in previous studies. Future research is needed to explore the effect of tail frequencies to explain the u-shaped distribution.
