Abstract
This experiment is a partial replication of Diemand-Yauman et al.’s (2011) research into disfluency and learning, in which they demonstrated that material written in italicized or bold font (disfluent font) was better learnt and more easily recalled than material written in an easier to read (fluent) font (Diemand-Yauman et al., 2011). The aim of this experiment was to investigate if a list of words written in an italicized disfluent font would be better remembered than the same list written in a fluent font.
An independent samples design with 20 students chosen by opportunity sampling was used to test the experimental hypothesis: Significantly more words will be recalled from a 25-word list written in a disfluent font (Calibri italicized 12 pt) than are recalled from the same word list written in a fluent font (Calibri 12 pt). The null hypothesis stated: Any increase in remembered words from the 25-word list written in a disfluent (italicized) font will not be significant. Any observed increase is due to chance.
17 and 18 year old student participants were randomly allocated, by distribution of word lists, to the experimental (disfluent) or the control (fluent) group. They were given 10 minutes to learn the words on their list, and another 10 minutes to try and recall them in writing. The mean number of words remembered from the disfluent font word list was 19.6 with a SD of 2.76 and the mean number of words remembered from the fluent font word list was 17.5 with a SD of 2.17. The Mann-Whitney U test was applied and the difference was found not to be significant at the p< 0.05 level. Therefore the null hypothesis was accepted, and the conclusion drawn that disfluency does not result in a significant increase in recall.
