In Human Computer Interaction, appropriate feedback is especially important when an error occurs. This work compares implications for user's psychological reactance and acceptance of two different types of error and their representations through feedback. Reactance and acceptance levels were measured after presenting feedback that allows a conclusion on the cause of an occurred error and feedback that fails to do so. It was found that reactance levels were significantly higher and acceptance levels significantly lower in the latter case. Suggestions for appropriate system design are discussed.
