Iconic Words Are Associated With Iconic Gestures

Area of Science:

• Cognitive Science
• Linguistics
• Psychology

Background:

• Iconicity, where words sound like their meaning, is a recognized feature of language.
• Previous research has established the existence of iconic words in English.
• The relationship between word iconicity and the use of iconic gestures remains less understood.

Purpose of the Study:

• To investigate whether highly iconic English words are more frequently accompanied by iconic gestures.
• To compare gesture rates between high and low iconicity words, controlling for confounding factors.
• To explore the influence of word type (verb vs. adjective) and syntactic properties on iconic gesture production.

Main Methods:

• A large-scale quantitative study analyzed 5,725 tokens from the TV News Archive.
• Words were categorized as high or low in iconicity and coded for gesture occurrence and iconicity.
• Analyses controlled for perceptual strength, part-of-speech, syllable length, and syntactic isolation.

Main Results:

• High iconicity words exhibited a higher overall gesture rate (69%) compared to low iconicity words (56%).
• Iconic gestures were significantly more frequent with high iconicity words (24%) than low iconicity words (11%).
• This effect was more pronounced for verbs than adjectives and persisted after controlling for sensorimotor strength.

Conclusions:

• Iconicity in spoken language is multimodal, with speech and gesture often synchronizing.
• Word-level iconicity is a significant predictor of iconic gesture use, independent of sensorimotor properties.
• Syntactic factors may also influence the production of iconic gestures alongside word iconicity.
