Productivity matters for the neural processing of novel words, but not existing ones

Key Points

To examine how productivity affects neural processing of novel and existing words in the brain.
Used a design manipulating plausible novel words to assess their processing in the brain.
Measured brain activity in the temporal and frontal lobes during word processing.
Analyzed behavioral responses to the acceptability of novel words.
No significant difference in neural processing of novel versus existing words in the temporal and frontal lobes.
Productivity influenced processing of novel words, with the ‘deriver’ combination showing the most significant differences.
Novel words increased in acceptability, with ‘deriver’ accepted 69% of the time.

Abstract

• Our design manipulates plausible novel words to study their processing in the brain. • Existing words and their novel counterparts had no difference in their neural processing in the temporal and frontal lobes. • Productivity has an elevated role for novel words but not existing ones since only the first had differences in processing. • Among novel words, the most productive V-er ‘ deriver ’ combination differed most significantly in processing. • Behaviorally, novel words' productivity increased their acceptability, with ‘deriver’ words beingaccepted 69% of the time.
