Abstract: Identifying emotions in people with severe and profound intellectual disabilities is a difficult
challenge. Since self-reports are not available, behaviour is the most used source of
information. Given the limitations and caveats associated with using behaviour as the sole
source of information about their emotions, it is important to supplement behavioural
information with information from another source. As it is accepted that emotions consist of
language, behaviour and physiology, in this article we investigated if physiology could give
information about the emotions of people with severe and profound intellectual disabilities.
To this aim we tested hypotheses derived from the motivational model of Bradley Q3 and
Lang (2009) about the relation between heart rate and the valence of emotions and between
heart rate, skin conductance and skin temperature and behavioural expressions of
emotions of people with severe and profound intellectual disability. We presented
27 participants with 4 staff-selected negative and 4 staff-selected positive stimuli. The
situations were videotaped and their heart rate, skin conductance and skin temperature was
measured. Each behaviour of the participant was coded using the observational method
developed by Petry and Maes (2006). As hypothesized, we found a lower heart rate when
participants were presented with negative stimuli than when they were presented with
positive stimuli in the first 6 s of stimuli presentation. Their skin temperature was higher for
the expression of low intensity negative emotions compared to the expression of low
intensity positive emotions. The results suggest that, as with people without disability, heart
rate and skin temperature can give information about the emotions of persons with severe
and profound ID.
