Replicating Attribute Amnesia effect in the single-stimulus design

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.
