In poetry, if meter has to help memory, it takes its time

Area of Science:

• Cognitive Psychology
• Linguistics
• Neuroscience

Background:

• The cognitive schema theory posits that poetic meter aids verbal memory.
• Classical Italian poetry, specifically the works of Dante and Ariosto, serves as the corpus for this investigation.
• Key components of meter—rhyme, accent, and verse length—are examined for their mnemonic contributions.

Purpose of the Study:

• To empirically test the hypothesis that poetic meter functions as a cognitive schema enhancing verbal memory.
• To determine the individual and combined effects of rhyme, accent, and verse length on memory recall.
• To explore the cognitive costs associated with activating metric schemata.

Main Methods:

• Generation of meaningless poems by inserting prosody-invariant non-words into canonical Italian poetic passages.
• Systematic ablation of meter components: rhymes removed, accent patterns altered, syllable counts modified.
• Presentation of modified poems to native Italian speakers for recall of target non-words, with reaction times recorded.

Main Results:

• Dante's meter integrity showed no significant impact on memory performance.
• For Ariosto's poetry, removal of each metric component led to proportional memory degradation.
• Metric versions of poems elicited longer reaction times, suggesting a cognitive cost for schema activation.

Conclusions:

• The findings challenge the universal applicability of poetic meter as a mnemonic aid.
• Results provide evidence for schema theories, particularly high-level interactions between procedural and episodic memory.
• Metric plausibility, rather than meter itself, may be the crucial factor in memory enhancement for certain poetic traditions.
