**General** These are the data and stimulus code from the following publication: Rademaker, R.L., Bloem, I.M., De Weerd, P., & Sack, A.S. (2017). The impact of interference on short-term memory for visual orientation. Journal of Experimental Psychology: Human Perception and Performance, 41(6): 1650–1665. **Data** Behavioral data for each subject in each experiment (E1 through E4) is combined in a single .mat file (data were obtained across several days). Eye dominance data (collected for Experiment 4) is also included here. Data have been anonimized (subject initials were used as identifiers during data acquisition). **Stimulus Code** The original experimental scripts (using Matlab & the Psychtoolbox) used to run the 4 experiments at Maastricht University, the Netherlands, are named E1.m through E4.m. Prior to Experiment 4 we tested subject's eye dominance, the script to do this is provided here also. The monitor was gamma corrected, and this correction differs from monitor to monitor, which is why we have not supplied the gamma lookup table (run this code after commenting out the lines where this correction is applied – or replace it with your own correction). To run successfully you need to create a folder called "Data" in the same directory from which you will run the stimulus script.
