The effects of repetition frequency on the illusory truth effect

Cognitive Research: Principles and Implications

Table 2 Experiment 2 truth ratings as a function of repetition condition and the pairwise comparison effect sizes between repetition conditions

	Number of Session 1 repetitions
	0 (new)	1	9	18	27
Ms and SDs of truth ratings	M = 3.64 SD = 0.65	M = 4.26 SD = 0.83	M = 4.78 SD = 1.01	M = 4.72 SD = 1.02	M = 4.87 SD = 0.99
0 (new)	–	d = 0.88*	d = 1.02*	d = 0.96*	d = 1.13*
1		–	d = 0.62*	d = 0.49*	d = 0.80*
9			–	d = 0.11	d = 0.17
18				–	d = 0.28
27					–

Note: Average truth ratings, and their standard deviations, are presented in the first row on this table. Bonferroni-adjusted post hoc comparisons were used to compare the repetition conditions. Significant differences between conditions (p < .05) are indicated in bold (and also with an asterisk)
