A schematic diagram of a typical trial in the preference estimation task. In each trial, the participants (Perceivers) were asked to guess each target's actual preference for a given item. The target's face photo (perceiver's face photo) was shown for 3 s in the target-trials (self-trials), and a photo of the item was displayed after 1~3 s. The perceivers had to estimate within 3 s how much the target liked the presented item on a 4-point scale shown below the item. Immediately after the response, their choice was shown on the screen for 0.5 s. In the self-trials, the perceivers reported their own preference for the item.
