Memory strength, not a separate clock, may explain interval timing. This memory decay model unifies proportional timing and Weber-law properties, offering a new perspective on time perception.

Area of Science:

Cognitive Psychology
Neuroscience
Behavioral Science

Background:

Traditional models propose a dedicated pacemaker-counter mechanism for interval timing.
Recent research suggests memory processes might underlie time perception.

Purpose of the Study:

To investigate the role of memory strength in interval timing.
To explore if memory decay dynamics can explain various timing properties.

Main Methods:

Inferred memory decay from habituation properties.
Applied this model to explain proportional timing and Weber-law effects.

Main Results:

Memory strength decay provides a unified explanation for interval timing.
This model accounts for proportional timing and the Weber-law property.

Conclusions:

Memory strength decay is a viable alternative to pacemaker-counter models for interval timing.
This approach offers a unified framework for understanding temporal cognition.
