Emotion Recognition Task (ERT)
Overview
ERT measures the ability to identify emotions in facial expressions. The participant is shown a series of faces which appear on the screen briefly and asked to identify the emotion (happiness, sadness, anger, disgust, surprise and fear).
Administration Time
Around 10 minutes, depending on level of impairment.
Task
One hundred and eighty stimuli, which are computer morphed images derived from the facial features of real individuals each showing a specific emotion, are displayed on the screen, one at a time, in two blocks of ninety. Each face is displayed for a short while (200ms) and then immediately covered up, and then six buttons are displayed, each describing an emotion which could be portrayed in the photograph. The participant must decide which is the appropriate button to describe the emotion and touch the button. There are fifteen different photographs for each of the six emotions, each showing different levels of intensity.
Outcome Measures
The outcome measures for ERT cover percentages and numbers correct or incorrect, and overall response latencies. Results can be looked at across individual emotions, or across all emotions at once.
Test
ERT is available for clinical trials immediately, and will be available for academic research in CANTABeclipse 5. Please contact us for further information.
ERT takes around ten minutes to administer in healthy individuals.
