Replicating Attribute Amnesia effect in the single-stimulus design

<p>Attribute Amnesia refers to the phenomenon that subjects fail to report some features (e.g., colour) of a stimulus after they have been asked to repetitively report some other features (e.g., numeric parity) of the same stimulus. This effect has shown strong replicability in the multi-stimuli design, in which there is normally one target among three distractor stimuli. Recently, Wang et al. (2021) furtherly showed the robustness of this effect when there was only one stimulus on the screen. As the main experiment of the current project will be conducted online, we aim to pre-register a replication attempt of Experiment 1 of Wang et al. (2021) in the online-experiment setting. This study shows that one can indeed replicate previous in-lab experiments on attribute amnesia in the online setting, demonstrating convincing online data quality for serious investigations. The functions of Webcam-based eyetracking from Labvanced also make rigorous environmental control and recording saccadic data possible.</p>
