As previously mentioned, Balint's syndrome patients have provided support for the feature integration theory. Particularly, Research participant R.M., a Bálint's syndrome sufferer who was unable to focus attention on individual objects, experiences illusory conjunctions when presented with simple stimuli such as a "blue O" or a "red T." In 23% of trials, even when able to view the stimulus for as long as 10 seconds, R.M. reported seeing a "red O" or a "blue T". This finding is in accordance with feature integration theory's prediction of how one with a lack of focused attention would erroneously combine features.
