Results of a repeated measures ANOVA for the different curve parameters; means in the same row sharing the same superscript letter do not differ significantly from one another at α = 0.05; degrees of freedom (df) for x-threshold: 1.5,41.6 (Greenhouse-Geisser corrected); df for y-threshold: 1.3, 33.9 (Greenhouse-Geisser corrected); df for slope: 2,54.
