The (Spatial) Memory Game: Testing the Relationship Between Spatial Language, Object Knowledge, and Spatial Cognition

We present a protocol to explore the relationship between spatial language production, spatial memory, and object knowledge. The procedure allows experimental manipulation of, and control over, conditions of object knowledge, language at instruction, and physical location, thus teasing apart cognitive and linguistic models describing interactions between these...

A Real-world What-Where-When Memory Test

The Real-World What-Where-When memory test is a novel episodic memory test, in which participants need to recall which objects have been hidden in which locations on which of two distinct occasions. It is easy to run and is sensitive to normal cognitive...

Eye Tracking, Cortisol, and a Sleep vs. Wake Consolidation Delay: Combining Methods to Uncover an Interactive Effect of Sleep and Cortisol on Memory

We present a protocol used to discover an interactive effect between sleep and cortisol on memory consolidation, particularly for negative arousing images. Specifically, the experimental design utilizes eye tracking, salivary cortisol analysis, and behavioral memory testing – methods that can be used with both healthy and clinical...

Summary

This summary is machine-generated.

Working memory storage mechanisms are debated. This study shows that sensory recruitment for memory fades, unlike local perceptual interactions, suggesting distinct memory and perception structures.

Background:

Working memory storage mechanisms are debated.
The sensory recruitment hypothesis proposes shared neural substrates for memory and perception.
This implies perceptual mechanisms also shape maintained memory content.

Purpose of the Study:

To test the sensory recruitment hypothesis using the Direction Illusion.
To investigate how perceptual interactions change during the transition from perception to working memory.
To differentiate between global and local feature interaction mechanisms in perception and memory.

Main Methods:

Participants memorized directions of two random dot patterns.
The Direction Illusion (mutual repulsion of motion directions) was used.
Stimulus temporal and spatial separation were manipulated across three experiments.

Main Results:

Mutual motion repulsion occurred only with simultaneous stimulus presentation.
Proactive repulsion vanished at longer inter-stimulus intervals, while retroactive attraction persisted.
Repulsion reappeared when stimuli shared the same spatial position.

Conclusions:

Repulsive mechanisms shaping perception fade during memory consolidation, indicating differences between perceptual and mnemonic representations.
Global perceptual interactions diminish during memory formation.
Local interactions persist, suggesting distinct mechanisms for global and local feature processing in memory.
