Definitions:

Decay Theory

Theory stating that when an individual learns something new, a neurochemical memory trace forms, but over time this trace disintegrates; suggests that the passage of time always increases forgetting.

Neurochemical Memory

Refers to how memories are stored and retrieved through the action of neurotransmitters and neural pathways in the brain.

Memory Trace

The physical change in the brain, presumably involving synaptic modifications, that represents the memory of an experience.

Proactive Interference

Proactive interference is a cognitive phenomenon where older memories hinder the recall of newer information.
