Abstract

Cilj ovoga istraživanja je utvrditi kolika je minimalna količina informacija potrebna za uspješno prepoznavanje ljudskih emocija radosti, tuge, straha, iznenađenja, srdžbe i gađenja prikazanih izražajem lica. Isto tako, pokušava se odgovoriti na pitanja ovisi li količina informacija potrebna za točno prepoznavanja emocija preko izražaja lica o tome prikazuju li se procjenjivaču ugodne ili neugodne emocije, ovisi li o spolu modela na fotografiji i ovisi li o spolu procjenjivača. Početni uzorak sačinjava 30 muških i 30 ženskih sudionika studenata Sveučilišta u Zagrebu i mladih, radno aktivnih osoba, no nakon izuzimanja sudionika koji nisu uspješno prepoznali barem jednu od emocija, obrada se vrši na uzorku od 49 sudionika. U provedbi istraživanja korišten je slobodno dostupan program Redundancy, namijenjen ispitivanju perceptivne zaokruženosti. Procjenitelji su testirani pojedinačno preko prijenosnog računala, a zadatak im je bio prepoznati koja se emocija prikazuje na fotografiji. Ukupno im je prikazano 12 fotografija, od čega šest osnovnih emocija s muškim modelom i šest osnovnih emocija sa ženskim modelom. Rezultati istraživanja ukazuju na to da minimalna količina za točno prepoznavanje emocija preko izražaja lica ovisi o tome prikazuju li se procjenjivaču ugodne ili neugodne emocije, o samoj vrsti prikazane emocije te o spolu modela na fotografiji. Najmanje informacija za točno prepoznavanje potrebno je za emociju radosti, dok je najviše informacija potrebno za emocije tuge i gađenja. Što se tiče spola modela koji izražava emociju, za emociju gađenja, iznenađenja i tuge kod muških modela treba značajno manje informacija nego za ženski model, dok je obrnuto kod emocije srdžbe.

Abstract (english)

The aim of this study was to determine the minimal amount of information needed for successful recognition of human facial expressions of emotions happiness, sadness, fear, surprise, anger and disgust. In addition, the aim was to determine whether the amount of information needed for accurate recognition of facial expressions of emotions depends on pleasant/unpleasant category, gender of the model in the photo and gender of the examiner. The initial sample consisted of 30 male and 30 female young adults, but after the exclusion of participants who have not successfully recognized at least one of the emotions, the sample was reduced to 49 participants. A freeware software Redundancy was used for perceptive efficiency evaluation. The participants were tested individually on portable computer, and their task was to identify which emotion was displayed in the photo. In total, there were 12 photographs of which 6 showed basic emotions by a male model and 6 showed basic emotions by a female model. Study suggests that the minimal amount of information for accurate recognition of facial expressions of emotions depends on the emotion, valence of presented emotions, and gender of the model in the photograph. Participants needed the least information for accurate recognition of happiness, and the most information for accurate recognition of sadness and disgust. As for the gender of a model that expresses emotion, participants needed significantly less information to accurately recognize disgust, surprise and sadness in male than in female models, while the opposite was found for anger.
