See here for a python implementation: ---------- In this project, we explored how objects are represented in mind using a novel shape-color "conjunction" task to reconstruct memory resolution within a single behavioral response. In this task, shapes from the *Validated Circular Shape Space* (Li, Liang, Lee, & Barense, 2020; were displayed along the circumference of a 2D circle and colors from a circle defined on CIELAB color space (L = 70, a = 20, b = 38, radius = 60 units) were displayed along the radius. Participants can then navigate along shape and color space simultaneously in order to reconstruct a target object. See the wiki for more information about the task and pre-generated shape-color object stimuli. Anonymized data from Experiment 1 and Experiment 2 are provided under "Files".
