Visual working memory content influences correspondence processes.

Abstract

Representing objects as continuous across time requires the establishment of correspondence, whereby current stimuli are represented as deriving from the same object as earlier stimuli. Spatiotemporal continuity and surface-feature similarity play important roles in these correspondence processes. Because objects are often represented across extended periods of time, visual working memory (VWM) content should also play a role in object correspondence. We tested this prediction using Ternus motion. Displays consisted of three-disk arrays that shifted horizontally by one position between frames. Depending on how correspondence is resolved, Ternus displays are perceived as group motion, where all three disks appear to move together, or element motion, where one disk appears to jump across the others. Reports of which motion is perceived provide an index of how correspondence was resolved. Ternus displays were adapted such that the color of some disks biased element motion while the color of others biased group motion. Maintaining one or the other of the colors in VWM for later report systematically biased which type of motion was perceived (Experiments 1 and 2). When color was incidental to the VWM task, however, it did not (Experiment 3). These results confirm that VWM content contributes to object correspondence.

Transfer Effect of Cognitive Advantages in Visual Working Memory Capacity: Evidence from Elite Football Players

“…The possible reason was that, for the elite football players, the memory advantage was more dependent on their higher information processing efficiency in everyday conditions. Hein’s research shows that the working memory content can have an impact on subjects’ communication processes [ 39 ]. This further explains the differences in the VWMCs under different conditions.…”

Is core knowledge in the format of LOT?

“…Recent evidence casts doubt on strict limitations on which properties are part of the "label." although earlier theories took spatiotemporal indices to be uniquely privileged (e.g., Leslie, Xu, Tremoulet, & Scholl, 1998), surface features like color can play an indexing, referenceguiding role in object files, even in ordinary contexts (Hein, Stepper, Hollingworth, & Moore, 2021;Hollingworth & Franconeri, 2009;Moore, Stephens, & Hein, 2010). However, object files routinely store some featural information (e.g., color or orientation) while completely failing to use it to guide reference to objects (e.g., Gordon & Vollmer, 2010;Gordon, Vollmer, & Frankl, 2008;Jiang, 2020;Richard, Luck, & Hollingworth, 2008;see Quilty-Dunn & Green, 2023, for a review).…”
