Adaptation improved discrimination thresholds, evidenced by a main effect of adaptation condition (F 1, 77) = 58.5, p < 0.001; Fig. 2a).
The criterion shift effect was supported by a main effect of time on criterion (F 3.3,59.9)=2.938, P=0.036, ηP2=0.140), and the direction of the shift was confirmed by planned t-tests comparing the terminal criterion against the initial criterion (t(18)=2.848, P=0.011, Cohen's d=0.692) and against a neutral criterion of zero (t(18)=3.730, P=0.002, Cohen's d=0.859).
In both tasks alpha desynchronized during observations of movements as compared to the subsequent pauses, as indicated by a main effect of Period, F 1, 13) = 11.2, p<.005.
Inter-fixation distance was characterized by a main effect of response F (1, 68) = 11.36, P<0.001, with inter-fixation distance smaller (i.e., more clustered fixations) for "remembered" photos than "known" photos.
Number of eye-fixations were characterized by a main effect of response F (1, 68) = 4.3, P<0.05, with average number of fixations greater for "known" photos than "remembered" photos.
Participants evaluated music segments preceded by affectively congruent visual word primes significantly faster than music segments preceded by affectively incongruent word primes, as indicated by a main effect of congruence [F 1,30) = 27, p<0.01].
A test for the interaction of QTL by environment can be carried out by including a main effect QTL.
For each independent variable, effects were estimated by both a main effect term (effect on initial fertility at the birth of the study child) and an interaction term with time (effect on rate of fertility change per year).
The genetic risk scores were tested for association with the rate of change in total body (excluding skull) BMD, BA and BMC, by including a main effect and an interaction between the age function and the score in the fixed effects part of the model.
In our study, TGFB1 was significantly up-regulated by estradiol as a main effect, supporting its important role in cardiovascular function.
When preference data were analyzed separately by age, only a main effect of day emerged in the adolescents [ F 7, 98) = 2.89, P < 0.01], with preference scores peaking on Day 3 and declining thereafter.
