Multilevel modelling in JASP

Hi,

I am a newbie here and looking to answer my RQ: How does human comfort level with the robot changes given 4 different ways of expressing emotions? using multilevel modelling.

• Independent Variable: 4 different ways of expressing emotions
• Dependent Variable: Human comfort level responses from 0 - 100 on a Likert scale
• This experiment is a between group design i.e, 4 different groups of participants interacted with 4 different ways of expressing emotions.
• Each participant interacted with the robot for 15 minutes with giving human comfort level rating after each minute.
• Robot displays negative emotions always at the start of 5th, 8th, 12th and 13th minute.

With a multilevel model that models the 15 responses (random intercepts for participants), and with a lag factor in the model, I wish to see how much time it take for human comfort to build up again after negative emotions and if that differs across 4 ways of expressing emotions.

The mean responses of human comfort looks like this:

I am not sure how can I do this in JASP(?)

Hi Mark,

I am not sure either. I think it is important first to identify the desired statistical approach. Also, it seems to me that expression of negative emotion by the robots prompts people to show higher comfort levels? But I am not sure why the comfort level goes down -- maybe I don't understand at what point the robot was expressing negative emotions. This strikes me as a pretty complex analysis, particularly because you need to model the change in comfort levels as a function of the rounds...
