The variations in iconicity and indexicality in sign languages across cultures significantly influence the cognitive processing and production of metaphoric and metonymic extensions in gesture-based storytelling. Here's a structured summary of the key points:

  1. Iconicity and Metaphors:

    • Visual Imagery: Sign languages with high iconicity, where signs resemble their referents, facilitate metaphoric expressions by providing a direct visual connection. This makes metaphors more intuitive and impactful, as seen in gestures like flapping hands to represent flying.
    • Cultural Expression: Cultures valuing visual expressiveness may use more iconic signs, leading to metaphors that are vivid and easier to grasp, enhancing storytelling through imagery.

  2. Indexicality and Metonymies:

    • Spatial Reference: Indexicality, involving pointing or indicating, supports metonymic expressions by using spatial references. This helps in setting the narrative scene and guiding the audience through spatial relationships.
    • Cultural Storytelling: Cultures with more indexical signs may structure stories around spatial elements, making metonymies based on proximity or contiguity more prevalent.

  3. Cognitive Processing:

    • Visual vs. Spatial Processing: Iconic signs may engage visual processing areas of the brain, while indexical signs might activate spatial awareness regions. This can lead to cultural differences in how metaphors and metonymies are neurologically processed.
    • Efficiency in Processing: Individuals from cultures with high iconicity may process visual metaphors more efficiently, whereas those from indexical cultures might process spatial metonymies more effectively.

  4. Narrative Impact:

    • Vivid Narratives: Iconicity enhances metaphoric impact, creating clear and powerful images. Indexicality aids in structuring narratives spatially, guiding the audience through the story's physical and conceptual space.
    • Cultural Variations: These elements influence storytelling styles, with iconicity fostering vivid imagery and indexicality supporting spatially guided narratives, leading to diverse storytelling approaches across cultures.

In conclusion, iconicity and indexicality in sign languages shape the use of metaphors and metonymies in storytelling, affecting both production and cognitive processing. These elements not only influence the vividness and structure of narratives but also the cognitive strategies employed by different cultures, resulting in rich and varied storytelling traditions.
