Repeated measures general linear models were used to examine
female looking responses to the two size variant conditions. We
conducted two models, one in which the number of looks given to
the large versus small male was entered as a within-subjects factor,
and another with the duration of looks given to the large versus
small male entered as a within-subjects factor. The male exemplar
used to create the playback stimuli was entered as a betweensubjects
factor (comprising four levels) in both models to test
whether females responded differently to the four different male
exemplars used to create the playback sequences
