Facial Expressions of Emotion: Stimuli and Tests (FEEST)
Andy Young, David Perrett, Andy Calder, Reiner Sprengelmeyer and Paul Ekman, 2002

Assess recognition of facial expressions of emotion

Age Range:

Individual - Untimed

The ability to interpret the moods and feelings of other people is an important social skill. Misinterpretation of affect can lead to misunderstanding and inappropriate social behaviour.

For humans, facial expressions provide important indicators of emotion. Basic emotions are expressed and recognized in similar ways throughout the world. Functional imaging studies have uncovered some of the mechanisms involved in neural responses to perceived emotion, and impaired recognition of facial expressions has been documented after a number of types of brain disease.

The FEEST makes available a unique resource, involving a wide range of high-quality materials for assessing recognition of facial expressions of emotion. A key feature is that these materials include both standard tasks with control data and supplementary stimuli, which in the hands of those with appropriate experience, can be used to create new tests and experiments.

The stimuli include the six basic emotions from the Ekman and Friesen series (happiness, surprise, fear, sadness, disgust, anger), as well as the neutral faces. Computer-morphing and caricaturing procedures have been used to create continua varying in intensity. Clinicians and researchers can therefore create tasks that can be graded in difficulty, ranging from subtle to intensely expressed emotions.

These FEEST has many potential applications in neuropsychology, clinical psychology, experimental psychology and functional imaging studies. Published papers have reported studies in each of these areas, a selection of which are detailed below as well as the substantial test manual.

Please note that the basic licence fee provides for use of the FEEST stimuli on a single computer. We offer special terms for those wishing to use the stimuli on multiple workstations. Please contact Sue Overy for further details.
