Snap Back to Reality: Comparing Real-World Spatial Memory in the "Wild" vs. in the Lab

This study compares real-world spatial memory tasks using a smartphone app with traditional lab-based tasks and finds strong correlations between some measures but also unique patterns in app-based performance.

Experimentally-induced encoding variability influences mnemonic discrimination: Evidence from human behavioral data and global matching models

The paper manipulates encoding variability in a mnemonic task and shows that increased repetitions of non-target stimuli impair mnemonic discrimination, supported by behavioral data and a global matching model.

Living off the grid: Spatial representations show systematic non-Euclidean distortions regardless of their age and how measured

The paper investigates spatial memory distortions across different environments and time scales, finding systematic non-Euclidean patterns that support the cognitive graph hypothesis over the cognitive map hypothesis.

Computational models suggest that human memory judgments exhibit interference due to the use of distributed representations

The paper uses computational models to show that human memory performance is better explained by distributed representations in the neocortex rather than hippocampal pattern separation.

Goal-centered representations in the human hippocampus

This study examines how the human hippocampus encodes contextual and goal information during goal-directed navigation, showing context-specific future goal representations and anticipatory activity patterns.
