Notes:
a
T-tests assume unequal variances;
b
P values not shown are p > .1;
c
Milliseconds: the competitor onset and offset slope measurements correspond to the standard deviation (σ) or width of a Gaussian and are therefore represented in ms;
d
Proportion of total fixations;
e
Competitor peak height and offset baseline averages and standard deviations are not transformed so as to show meaningful measures. The statistics are performed on the transformed values.
