Perception is transformed by both stable and time varying (contextual) expectations. This influence is observable in the domain of orientation processing as cardinal bias (repulsion from more common vertical and horizontal orientations) and serial dependance (attraction towards recent stimuli) [1,2]. These biases operate on vastly different time scales and have typically been studied in isolation. Investigating the properties of these two biases in tandem may reveal important insights into general principles of perception (efficient coding, Bayesian inference) that are obscured when studied in
