Abstract

Real-World Objects Are Represented in Visual Long-Term Memory Both as Unbound Features and as Bound Objects.

Highlights

Specialty section: This article was submitted to Cognition, a section of the journal Frontiers in Psychology
In a paper by Utochkin and Brady (2020), the authors conclude that objects are stored as sets of independent features, based on a series of experiments showing that object features are only weakly bound and can be unbound in long-term memory, a conclusion which is supported by a previous study of Brady et al suggesting that objects features are forgotten independently of each other (Brady et al, 2013)
In a paper by Balaban et al (2019), the authors conclude that objects are stored as unitary feature-bound representations, based on a series of experiments following the protocol of the study by Brady et al (2013; Experiment 2) but analyzing the data with an alternative analytical method, suggesting that object features are forgotten in a dependent manner

Summary

Introduction

Specialty section: This article was submitted to Cognition, a section of the journal Frontiers in Psychology. Recent research has shown that observers store a vast amount of viewed real-world objects in visual long-term learning with high precision (e.g., Standing, 1973; Vogt and Magnussen, 2007; Brady et al, 2008), even when objects have been processed without any attention and intention of learning (Kuhbandner et al, 2017).
