Second-order amplitude modulation and texture exemplar discrimination. The black symbols show the response to second-order amplitude modulated Gaussian noise exemplar discrimination as a function of modulation rate. Error bars indicate the standard error. The blue symbol indicates exemplar discrimination performance for complex second-order amplitude modulated Gaussian noise. The green symbol indicates exemplar discrimination performance for synthetic sound textures that include all indicated texture statistics (including second-order amplitude modulation statistics). The red symbol indicates exemplar discrimination performance for top-8 synthetic (Experiment 2) sound textures that include all indicated texture statistics.
