This article provides a background for a new database of basic emotional expressions. The goal in creating this set was photorgaph provide high quality photographs of genuine facial expressions. The novel approach taken Exlression this study was also used fafial establish whether a given expression was perceived as intended by untrained judges. The judgment task for perceivers was designed to be sensitive to subtle changes in meaning caused by the way an emotional display was evoked and expressed. Consequently, this allowed us to measure the purity and intensity of emotional displays, which are parameters that validation methods used by other researchers do not capture.
The final set is comprised of those pictures that received the highest recognition marks e. Descriptions of the accuracy, intensity, and purity of displayed emotion as well as FACS AU's codes are provided for each picture. Given the unique methodology applied to gathering and validating this set of pictures, it may be a useful tool for research using face stimuli.
Introduction The human face is considered to be a unique social stimulus that provides crucial information about another person. Information such as identity, gender, age, ethnicity, social origins, and physical attractiveness is easily accessible from the face, and plays a fundamental role in forming impressions about others. Moreover, a special place in facial communication is reserved for expression of emotions. A review of recently published papers indicates that facial expressions figure prominently in research on almost every aspect of emotion, including psychophysiology Dimberg et al.
Facial expressions are central to several leading theories of emotion Tomkins, ; Ekman, ; Izard, and continue to be debated in emotion science, as their meaning, rules of display, and interpretation are still in question Ekman,; Fridlund, ; Russell, ; Wierzbicka, Even so, the observed cross-cultural easiness and unambiguity of so-called basic emotion expression, as well as the similarity of evoked reactions, makes it a crucial affective stimulus in multiple research purposes see Ekman and Rosenberg, Therefore, access to standardized sets of pictures containing facial expressions of emotions is an important factor for improving research quality. This article reports the background information for a new database of basic emotional expressions: Every model was photographed neutrally and shows one of the seven basic emotions: This set includes pictures of 32 models: Chinese, French-Canadians, and sub-Saharan Africans—eight for each group, four male and four female.
Each individual was photographed while expressing five of the basic emotions happiness, anger, fear, sadness, and disgust and a neutral expression. Surprise was not included, and the pictures were standardized using FACS. This set contains pictures of the six basic emotions and includes directness of the display with pictures taken from five different angles. Actors were instructed to pose eight expressions: For each expression, separate open- and closed-mouth versions were posed, except for surprise, which was only posed with an open mouth. The set was standardized according to the ratings of independent judges. Also worth mentioning are several more recently developed sets. The set features only two European American and two West-African models four in total.
The RaFD includes averted and direct gaze orientations, and photographs taken from five different angles. The database contains 55 different facial expressions performed by 19 German participants. Finally, Ebner et al. In most of the sets described above e. However, current studies show the sensitivity of participants to genuine and posed emotional displays McLellan et al. Moreover, we can observe the diversity of ways individuals typically express their emotions Cohn et al. This may cause the expression of anger to include but not necessarily lowering brows, while upper lids might be alternatively tightened or pulled up, upper and lower lips might be tightened together, or upper lips pulled up.
To overcome the mentioned limitations in the case of our own set, the WSEFEP, the main idea was to elicit emotional states and then photograph them. Thus, the stimuli would include the characteristics of genuine facial expressions that closely resemble the natural way of emotion expression by individuals, and therefore allow for the highest possible level of ecological validity. As a result, participants were inclined not to pose but instead express felt emotions, which were elicited during photo sessions. Additionally, visible parameters of facial muscle activity were not used until selection of the obtained material began.
Another property differentiating WSEFEP from other sets of emotional expressions is the process of selection and evaluation.

The vast majority potograph the photographs from the described sets were first selected by their authors from a larger pool. Those photographs were then evaluated by independent judges and their evaluations were used to confirm proper categorization. In our case, a different strategy was applied. The choices of competent judges constituted the initial selection, whilst the final set consisted of the photographs that received the highest marks from independent judges.
Seemingly, Ebner et al. The patriarchal-choice method, which is bad in the literature midst audio emotion concepts e.
We first selected several pictures representing a given emotion for each displayer and then asked judges to evaluate them. The final set consisted of photographs that received the highest marks and then additionally were coded by a certified FACS coder. Moreover, we introduced a new method of validation in order to obtain a more precise description of the displayed emotions. The forced-choice method, which is criticized in the literature regarding basic emotion concepts e. Once you anticipate a genuine emotion happening, shoot! And not just one frame. Expressions change so rapidly that just one frame often misses the best moment of the expression.
When shooting more than one person, make sure you attend to all subjects, and try to anticipate the moment when they all have a great expression. This technique is certainly more time and image intensive than a couple snaps of fake smiles. But it rewards you with photographs that show something real. One frame to the next can look completely different! Which expression is the one you should go with? Expressions, after all, are subtle. Understanding more about facial expressions can make that sorting process far easier. You can quickly pick out the expression that is stronger than the other, because one has a deeper engagement of the naso-labial folds!!
But the value of understanding facial expressions goes much further. Are they feeling confused? You need to be able to recognize negative emotions, and adjust your approach appropriately. Carrying on blindly while someone is feeling unhappy is going to put them in a very unenjoyable position, and give them a bad experience with you from the get-go. Finally, understanding facial expressions can help you understand more about the messages you are communicating to your subjects. Your facial expressions will have a big impact on them, both in meetings, and especially during the shoot.
If you are unwittingly suggesting that you are upset or worried, they will quickly become uncomfortable or lose confidence in you. So you can see that understanding facial expressions can help both the creation of your images, as well as the client experience you provide. You are hired to show your clients in a joyful state. Happiness is shown in the lower face and the eyes. However, transient factors such as gaze direction and facial expression affect facial attractiveness, suggesting it is not. We compared the relative importance of variation between faces with variation within faces due to facial expressions. Each rater saw each model only once with a randomly chosen expression.
The effect of expressions on attractiveness was similar puotograph male and female faces, although several expressions were not significantly different from each other. Since the hard tissues of the face are photgoraph, people may still be able to perceive facial structure whatever expression the face is displaying, and still make attractiveness judgements based on structural cues.
