Self-control saps memory resources

“These findings strongly suggest that self-control and memory encoding share common brain structures and mechanisms, and compete with each other for them, and so support Chiu and Egner’s “inhibition-induced forgetting” hypothesis. These shared neural resources are limited, and so response inhibition quickly saps them, making fewer available for the encoding of memories. We already know that paying close attention to something can make us oblivious to other things that would normally be glaringly obvious, and future research will likely reveal more about how attention, memory, and self-control are linked to each other, and to other components of the brain’s executive function system.”
