Examining approach-avoidance responses to facial expressions using a tablet device

Approach-avoidance responses to facial expressions have been previously examined, but they are mainly based on contrasting two expression types. However, these examinations are limited; the approach-avoidance response differs depending on the combination of facial expressions. In the current study, the approach-avoidance responses to three expression types were examined using a tablet device. The avoidance response to the anger expression was confirmed, but the approach response to the happy expression was not confirmed. These results indicate that examining approach-avoidance responses using a tablet device is effective and that avoidance responses to angry expressions are robust.
