Effect of Intentional Sentences on Visual Attention to Human and Animal Pictures: Evidence from Eye Movements

This study explored the effect of specific vs. general sentences, describing intentional aspects of humans and animals on visual attention on face and body regions. A picture-sentence verification paradigm was used and eye movements were recorded as subjects looked at displays in the absence of any overt task. Results indicated higher visual attention to the body regions for sentences expressing specific intentional states for human pictures and not for animal pictures. A strong preference to look at the body regions in general was observed compared to the face regions. Results suggest that understanding intentional states of other agents requires focusing visual attention on the body region compared to the face region. The findings are discussed in terms of interaction of intentional states and visual attention.
