Steps to reproduce
A comprehensive list of spontaneous gestures commonly used in conversation was compiled to create the stimulus set, totaling 187 distinct distinctive and recognizable gestures (nonverbal language). To illustrate these gestures, we photographed six actors (three male and three female), instructing them to produce the gestures naturally via the Stanislavsky Actor’s studio methods. The photographs were taken in a professional studio, where the actors stood before the camera in a white hall under controlled lighting conditions. Each actor received the list of gestures and was asked to express them spontaneously. This process resulted in a total of 1,122 photographs—six for each of the 187 gestures. The gestures could be of three types: iconic (visual representations of referential meaning), deictic (gestures that indicate real, implied or imaginary persons, objects, directions) or emblematic (symbolic and conventional gestures that represent a standard meaning; e.g. the index and middle finger forming a ‘V’ for ‘peace’ or thumbs up for ‘good’). Each gesture was associated with a short verbal label, which could be congruent or incongruent with the image itself. Half of the images were assigned to the congruent condition, in which gestures were paired with matching verbal descriptions, while the other half were assigned to the incongruent condition, where gestures were paired with mismatched descriptions. The stimuli were carefully balanced so that each actor appeared in an equal number of congruent and incongruent conditions. Each gesture was associated with three congruent and three incongruent stimuli, ensuring that each verbal description appeared six times: three times with congruent images and three times with incongruent ones.
