Developing and validating an isotrigon texture discrimination task using Amazon Mechanical Turk

Seamons, John W; Barbosa, Marconi; Victor, Jonathan D; Coy, Dominique; Maddess, Ted


The human visual system must employ mechanisms to minimize informational redundancy whilst maintaining that which is behaviorally relevant [1, 2]. Previous research has concentrated on two-point correlations via spatial frequency and orientation tuning. Higher-order correlations are less studied, but they may inform us about cortical functioning [3]. Isotrigon textures can be used to probe the sensitivity of the human visual system as their structure is exclusively due to 4th and higher-order...[Show more]
