Abstract:
“To evaluate different emotions depicted on human behavior mathematically.”
The researches of Emotional psychology show that human emotion is composed by expression
behavior, subjective experience, and physiological activation. Facial expression is the main
symbol to identify emotion and expression is the external symbol of individual emotion and.
They are a primary means of conveying information among humans, and also occur in most
other mammals and some other animal species. To some extent Facial expressions and their
significance in the perceiver varies between cultures.
Usually people not only reflect feeling on their face, but also understand the feeling of others by
observing their facial expression. Some expressions can be accurately interpreted even between
members of different species- for example anger. Flowever, others are difficult to interpret even
in familiar individuals. For example, disgust and fear can be tough to tell apart, as faces have
only a limited range of movement, expressions rely upon minuscule differences in the proportion
and relative position of features on face, and reading them all requires a lot of considerable
sensitivity to same. Some faces are often falsely read as expressing some emotion, even when
they are neutral.
Theorists have argued that facial expressions of emotion serve the interpersonal function of
allowing one person to predict another’s behavior. Humans can extend these predictions into the
indefinite future, for example in the case of trait inference.
The hypothesis that facial expressions of emotion (e.g., happiness, sadness, fear, anger, and
disgust) affect persons’ interpersonal trait inferences (e.g., affiliation and dominance) were tested
in two experiments. Subjects rated the dispositional affiliation and dominance of target faces
with either apparently moving expressions or static. They inferred high affiliation and
dominance from happy expressions, low affiliation and high dominance from angry
