2. Reading the mind in the eyes: This is a validated test which identifies subtle impairments in social intelligence in otherwise intelligent adults. In this test the participant is presented with a series of 18 photographs (printed on paper) of the eye-region of the face of different actors, and is asked to choose which one word describes best what the person in the photograph is feeling. The participant is given a choice of 4 words. The participant is provided with a glossary of all terms that they will come across during this test and is asked to read through the glossary and the meanings of any words that they may not be familiar with during the baseline phase of the study. The participant is also advised that this glossary remains available to them for reference throughout this test.
