The combined visual scanning and verbal cuing intervention technique effectively improved facial affect recognition in TBI patients. BR struggled the most with labeling negative facial expressions, while a ceiling effect was observed for positive expressions at baseline.
A single case design (AB with follow up) was used to determine the effect of a combined visual scanning and verbal cuing intervention technique in improving facial affect recognition after traumatic brain injury (TBI). A 35-year-old male (BR) with impaired ability to recognize facial emotions as a result of severe TBI participated in the study over a 3-month duration. BR's mean accuracy across six universal static facial expressions of emotion improved significantly during intervention and was maintained at follow up. BR was most impaired in labelling negative (sad, angry, disgusted, anxious) versus positive facial expressions (surprised, happy). BR's accuracy to negative facial affect significantly improved during intervention. No further improvement was possible for positive expressions because a ceiling effect was observed at baseline. Overall BR's mean response times across emotions was reduced at baseline but increased significantly during intervention. This was also recorded for both positive and negative expressions, respectively. This novel combined intervention has potential to improve facial affect recognition after TBI. Further evaluation using a multiple-baseline design is recommended. Additional research is needed to determine whether improved facial affect recognition following training translates to improvements in social function and communication in people with TBI.
