Description: Humans use regularities in the environment to facilitate learning, often without awareness or intent. How might such regularities distort long-term memory? Here, participants studied/reported the colors of 360 objects in a long-term memory paradigm, unaware that certain colors were sampled more frequently overall. Across all objects, errors were often centered around the average studied color. These errors were indicative of feature-binding errors where objects were misremembered as the average studied color. We additionally observed subtler shift errors towards or away from the average color dependent on the color distance between the memory item and the average color. These findings bridge a gap between visual working memory and visual long-term memory literature by providing converging evidence for memory distortion mechanisms induced by a reference point.
