Please help me come up with some research questions regarding physical distance, body language and posture. We did an experiment where our participants are shown sets of images and they have to identify whether they are Fear, Anger, Happy or Sad.

1st experiment: Participants were shown 1 image: just body language/posture, NO facial expression
--- They were then tasked to identify what they think the emotion is based on the picture

2nd experiment: Participants were shown 2 images: the 2 images showed just body language/posture, NO facial expression, and there are different distances between them (close and far)
--- Here, they were asked to identify the emotion of 1 of the 2 images, based on the above mentioned criteria
