	55	+We used the "Wizard of Oz" method for recognizing agreement and disagreement, to make sure that the whole process did not depend on voice recognition being good enough. In practice, this meant that someone was pressing "y" and "n" on the keyboard according to the participants answers in a place the participant did not see, such as behind them.

57		-For the experiments, we'll be using the NAO robot platform, as well as a laptop for the participants to complete the questionnaires on. The questionnaire will be a combination of questions regarding the emotional state of the participants, their interaction with the robot, and the music included in the interaction. Food will be made available to see and measure how much people will eat.
	59	+For the experiments, we used the NAO robot platform, and a laptop to control it with. The participants completed the questionnaires on their phones by scanning a QR code. The questionnaires are a combination of questions regarding the emotional state of the participants, their interaction with the robot, and the music included in the interaction. Stroopwafels and water in a clean cup were made available to see and measure how much people ate.
