fMRI response as a function of the number of doorways in a scene. Each panel shows the mean univariate response within an ROI for stimuli grouped by the number of doorways they contain. Results are plotted separately for scenes with and without paintings (i.e., half of the stimuli contain a painting on any wall without a doorway). For scenes without paintings, the univariate responses in the EVC, OPA, and PPA increased in relation to the number of doorways [repeated-measures F-test for a positive linear effect of doorways; EVC: F(1, 11) = 8.51, P = 0.014; OPA: F(1, 11) = 8.50, P = 0.014; PPA: F(1, 11) = 14.96, P = 0.0026; RSC: F(1, 11) = 2.06, P = 0.18]. However, this effect was not observed in any ROI for stimuli with paintings (all P > 0.62), which are better matched on visual complexity across conditions with different numbers of doorways. This finding suggests that the linear trend in the univariate responses to the no-painting stimuli likely reflects an increase in visual complexity with the increasing number of doorways, rather than a specific effect of the number of pathways. Error bars represent ± 1 SEM.
