The listener automatically uses spatial story representations from the speaker's cohesive gestures when processing...

Area of Science:

• Cognitive Psychology
• Linguistics
• Neuroscience

Background:

• Gestures play a crucial role in communication, often conveying information beyond spoken words.
• Understanding how gestures contribute to cognitive processes like spatial representation is vital.

Purpose of the Study:

• To investigate whether cohesive gestures automatically establish spatial representations of story protagonists.
• To determine if these spatial representations remain active and influence processing in subsequent discourse.

Main Methods:

• Participants processed three-sentence discourses where initial sentences featured gestures consistently placing two protagonists in distinct spatial locations (left and right).
• A third sentence, lacking gestures, referred to one protagonist, requiring participants to respond by pressing a key.
• Response times were measured for spatially congruent and incongruent conditions relative to the established gestural locations.

Main Results:

• Reaction times were significantly faster in the spatially congruent condition compared to the incongruent condition.
• This performance difference occurred despite gestures not providing explicit cues for the correct response in the third sentence.

Conclusions:

• Cohesive gestures automatically construct and maintain spatial representations of narrative elements.
• These dynamically established spatial representations influence cognitive processing even in the absence of ongoing gestural input.
