* The relationship is seen from the viewpoint of the participant doing the task, e.g., “Child” means that the stimuli are of the child of the participant who performed the dot probe task.
† As we were interested in how closely bonded individuals attend to each other’s emotions, we focused mainly on families and friends. We did not collect a lot of participants with a more distant family relationship (e.g., aunts/ uncles, nephews/nieces, cousins), but decided not to remove the 2 participants with a niece or nephew.
‡ Note that this number is not the same as the one reported in the main text (N=449), this is because of a technical failure, the relationship data of 45 participants was not registered.
