Effects of emotion on the preceived performance of backchannel strategies
The effect of conversational emotion on the perceived performance of models of backchannel behaviour is evaluated. These are behavioural models which are used to appropriately provide feedback to a speaker in a non-obtrusive manner to display attention. The effects of anger and happiness on three models of behaviour are investigated: one proposed by researchers previously, one random, and one to copy human behaviour. The backchannel behaviour was performed by a robot. In a user experiment subjects were shown video recordings of this behaviour during conversation and were asked to rate the appropriateness of the behaviour. Significant effects of both differences in emotion and model on the perceived performance of backchannel behaviour have been found, but an interaction effect was absent.
