The influence of a speaker's presence on the perception of expertise and credibility in public

Abstract

Ovaj diplomski rad istražuje utjecaj izgleda i odijevanja govornika na percepciju stručnosti, vjerodostojnosti i autoriteta u javnom nastupu. U teorijskom dijelu analiziraju se aspekti neverbalne komunikacije s naglaskom na odjeću kao komunikacijski alat, simbolički značaj uniforme, diplomatsku i profesionalnu odjeću te ostale vizualne elemente izgleda govornika. Kroz kvantitativno istraživanje provedeno na uzorku od 219 ispitanika ispitani su stavovi publike o utjecaju različitih obilježja izgleda govornika (odjeća, šminka, frizura, glas, visina i stas) na percepciju njihove stručnosti i vjerodostojnosti. Rezultati su pokazali da profesionalan i uredan izgled, umjerena šminka, dubok glas i atletska građa pozitivno utječu na percepciju izlagača. Rad ukazuje na važnost svjesnog oblikovanja neverbalnih poruka u javnim nastupima, posebno u kontekstu predstavljanja stručnosti.This thesis explores the impact of a speaker’s appearance and clothing on the perception of expertise, credibility, and authority in public speaking. The theoretical framework analyzes aspects of nonverbal communication, focusing on clothing as a communication tool, the symbolic significance of uniforms, diplomatic and professional dress codes, and other visual elements of a speaker’s appearance. A quantitative study was conducted with 219 participants to examine how various features of a speaker’s appearance (clothing, makeup, hairstyle, voice, height, and physique) influence perceptions of their expertise and credibility. Results indicate that a professional and tidy appearance, moderate makeup, a deep voice, and an athletic build positively affect the audience’s perception. The thesis highlights the importance of consciously shaping nonverbal messages in public speaking, particularly when conveying professionalism
