Good exemplars of natural scene categories elicit clearer patterns than bad exemplars but not greater BOLD activity.

Accurate responses were significantly faster for good images than bad images (892 ms and 1028 ms respectively; t(8) = 8.82, p <0.001), and this effect was significant across all the categories (t(8) = 8.53, p <0.001 for beaches; t(8) = 6.27, p <0.001 for forests; t(8) = 4.42, p <0.01 for highways; t(8) = 5.2, p <0.001 for mountains and t(8) = 2.58, p <0.05 for offices) except for city streets in which the difference was marginally significant (t(8) = 2.10, p = 0.068).

The percent signal change was significantly higher for bad exemplars than good exemplars in PPA (t(7) = 4.34, p <0.01; see Figure 9 ) but failed to reach significance in RSC (t <1) and V1 (t<1).
