Perceived Aggressivity on Indonesian Male Face

A face can give information such as intelligence and aggresivity from the person. Aggresivity in this study was categorized into anger, hostility, physical aggression, and verbal aggression. The study is to assess Indonesian society capability to perceive aggressivity from Indonesian male face. The respondents were 100 Indonesian males in Institut Teknologi Sumatera (ITERA), ranging from 19-51 years old, whose facial photographs were taken. The respondents were filling the Buss-Perry Aggression Questionnaire (BPAQ; to measure aggression scale). The mean of their BPAQ scales (total aggression, anger, hostility, physical aggression, and verbal aggression) were 72.44±10.84, 17.37±3.97, 21.38±4.53, 18.97±4.65, 14.72±2.68, respectively. The average face was generated based on min-Q1 (LA) and Q3-max (HA) scale. Next, the aggresivity of averaged LA and HA faces were evaluated by raters. The raters consisted of 107 males and 101 females who were randomly recruited in ITERA and Lampung, ranging from 17-67 years old. This study demonstrated that education was a factor influenced aggeressivity in people (generalized linear model, p-value<0.05). Male raters could not discriminate aggressivity between two averaged face (X-squared = 2.103, p-value = 0.147). Female raters perceived LA face as HA face (X-squared = 7.222, p-value = 0.007). This result indicated that aggresivity of Indonesian people could not perceived on faces. Keywords : aggressivity; BPAQ; face; lampung; perception
