Mnemonic-trained brain tuning to a regular odd-even pattern subserves digit memory in children

Abstract

It is said that our species use mnemonics – that “magic of memorization” – to engrave an enormous amount of information in the brain. Yet, it is unclear how mnemonics affect memory and what the neural underpinnings are. In this electroencephalography study, we examined the hypotheses whether mnemonic training improved processing-efficiency and/or altered encoding-pattern to support memory enhancement. By 22-day training of a digit-image mnemonic (a custom memory technique used by world-class mnemonists), a group of children showed increased short-term memory after training, but with limited gain generalization. This training resulted in regular odd-even neural patterns (i.e., enhanced P200 and theta power during the encoding of digits at even- versus odd- positions in a sequence). Critically, the P200 and theta power effects predicted the training-induced memory improvement. These findings provide evidence of how mnemonics alter encoding pattern, as reflected in functional brain organization, to support memory enhancement.

Effectiveness of mnemonic instruction in enhancing of reading ability among learners with dyslexia in South Africa: analysis of age differences

“…Mnemonics is said to engrave an enormous amount of information in the brain (Pan, et al 2023). Constant recitation of rhymes and songs that are linked to content learnt, is vital for learners, let alone LWD, to grasp content for longer periods.…”
