Sackler Institute | NimStim Face Stimulus Set Agreement
Educational and Psychological Measurement. Validity was indexed as how accurate participants were at identifying each emotional expression, and these scores were high. To address nimmstim findings, face sets have been developed that consist of models from various backgrounds.
We failed to find studies that used databases of photographs compatible with the age of the study sample, regarding both the children and the elderly people.
Recognition of facial expressions in children, young adults and elderly people
The intensity is determined by the amount of relaxation of the facial muscles, when compared to a neutral emotional state. Researchers have artificially generated other comparison faces i. Human Perception and Performance21 3 Additionally, because these actors all live in the same metropolitan city within the U. In order to increase the number of participants for the validity ratings, in particular, male participants, we recruited a second group of participants, which comprised 34 volunteers from the New York Metropolitan area.
Early processing of the six basic facial emotional expressions.
Nimstim face stimulus set
Validation of the entire set was accomplished by asking participants to label each stimulus. Previous research using existing sets Ekman and Friesen, has established much of what is known about face processing.
However, this type of statistic does not account for false positives Erwin et al. For these reasons, this set may be a resource for scientists who study face perception.
The second digit identified the emotion outlined in the photo happiness, sadness, fear or anger. Nimztim the most important is the racial diversity of the actors. Tanakab Andrew C. Conversely, Durand, Gallay, Seigneuric, Robichon and Baudouin argue that the increase in the capacity for identifying facial expressions of sadness and joy occurs concomitantly.
When familiarity breeds accuracy: For the present study, we used the images of two women models 1 and 16 and two men models 37 and 41 outlining expressions of happiness, sadness, fear, anger and a neutral expression. Emotions of fear, anger and sadness had a similar recognition rate in the young adults and the elderly people, suggesting difficulty to distingue these expressions.

Infant Behavior and Development. The authors also found that the ability races recognize facial expressions of fear only equals the adult ability at around seven years of age, whist the ability to recognize the emotions of anger and disgust, reaches its optimal level between nine and eleven years of age.
The NimStim set of facial expressions: Judgments from untrained research participants
Fades results of psychometric evaluations of these stimuli are presented. Note — there is no model 4 or nimwtim Participants were provided with these definitions and asked to label each face as calm, neutral, or neither:.
The authors concluded that a change in the spatial pattern of faces placing them upside down or changing the rotation of elements, such as the eyes and mouth interferes in the recognition of facial expressions. The current study chose a semi-forced choice method that was less strict than forced choice while being more interpretable than the free label method. Scores varied considerably from one actor to another indicating that some actors expressed calm and neutral faces better than others.
To explain this improvement throughout development, the authors believe that there is a progressive increase nimtim the ability to identify configurational properties of faces.
Whereas most sets contain roughly or fewer stimuli Mandal, ; Ekman and Matsumoto, — ; Wang and Markham, ; Mandal et al. Contributions of amygdala and striatal activity in emotion regulation. Having untrained participants identify the emotions on the faces is the best way to assess how similar participants in future studies will interpret the expressions.
