AbstractThe human brain is known by its ability to modify and update existing memories, mediated by underlying neuronal plasticity. This ability is facilitated by two main phenomena, interference and generalization. Interference occurs when a new memory harms, or is being harmed by, a different memory that was acquired in temporal proximity to it. Generalization on the other hand, refers to the case in which a learned memory is expanded beyond its specific properties. While each of these two phenomena may be well known separately, we review recent evidence primarily in perceptual and motor skill memory, spanning synaptic, neural systems-level, and behavioral research, suggesting that although the outcomes are different, the underlying neural and behavioral processes responsible for their inducements share numerous commonalities. The reviewed literature may imply a common mechanism underlying these two phenomena, and suggests a unified framework of memory and learning in the human brain.Copyright © 2018 IBRO.
