To date, numerous studies have examined impression formation. However, the conditions under which we are more or less accurate remains unclear and very few studies investigated which traits or competencies characterise accurate judges. Therefore, the present study investigated two research questions: First, whether emotional competencies predict accurate personality judgements; and second, whether there is a linear link between the available cues and accuracy. 121 judges assessed eight features (openness to experience, conscientiousness, extraversion, agreeableness, neuroticism, intelligence, empathy, and cooperativeness) across three exposure modalities (picture, mute-video, and audio-video) over 30 target individuals in total. Three measures of emotional competencies (GERT, STEU, and TEIQue) were used as predictors for accuracy. Results showed that (a) amongst the three tests, only the GERT correlated positively with the accuracy in judgement and (b) that accuracy was lower in the picture condition as compared to the two video conditions whereas the two latter were not different.
