To investigate how the different pre-feeding trials affected this preference, for each trial, we calculated the number of W minus the number of M shared or chosen: (W M).
W e is the width of the distribution of participants selection coordinates over a sequence of trials computed from W e = 4.133SD where SD is the standard deviation of the selection coordinates reflecting the over-shoot or undershoot of the individual movements about the mean in the direction of motion [ 42].
We compared the mean of two trials, 1(W) and 1(Z), after a F-test for homogeneity of variance in all measurement criteria.
Sessions 57 60 comprised only test trials; thus there were six reinforced presentations of w, six of z, and 15 nonreinforced presentations of each transfer CS signalled by each occasion setter (15 A… w−, 15 A… z−, 15 B… w−, 15 B… z−, 6 w+−, 6 z+).
However, with parameters w, the number of trials, and p, the probability of success for each trial, the binomial random variable X is the sum of w independent and identically distributed Bernoulli random variables.
The Wilcoxon Matched Pairs Test further confirmed the significant effect of trial type, W(14) = 15, p = .02.02
A Wilcoxon Matched Pairs Test demonstrated no significant effect of trial type, W(14) = 31, p = .18 for the P400.
A Wilcoxon Matched Pairs Test demonstrated a significant effect of trial type, W(14) = 20, p = .04 for the P400.
A Wilcoxon Matched Pairs Test confirmed no significant effect of trial type, W(14) = 34, p = .24 for the Nc component.
