Speech as a Form of Social Status Signaling
Humans, much like animals, separate themselves into different social hierarchies often associated by some specific sort of status signal. While animals may assign hierarchies strictly through physiological measures, the Biosocial Model states that speech is often the strongest form of status signaling for humans. BIOPAC user Allan Mazur recently was part of the research team that ran a study performed at Syracuse University that sought to test certain aspects of the Biosocial Model through conversations between unacquainted men. The researchers sought to understand whether physiology of status was important in casual conversation and if human speech works to convey dominant signs, much like the theory states. Two separate studies were performed, one where the conversation was given no stakes and another where $20 was offered to the individual who the group agreed (through questionnaire) to be the conversation leader. A PPG sensor was connected to participants’ thumbs while a BIOPAC MP Data acquisition system with analysis software recorded and synchronized data with video recording. The researchers found that the results supported their hypothesis as individuals who were able to steer topics and bring up points for discussion were signaled as being the leader of the conversation. Talking turns were also shown to be more stressful than speaking turns (especially in low-ranking members) showing physiologically that speech is a stress based mechanism for status allocation amongst humans.
