Abstract

This science fair project was done to find out if girls are better than boys at identifying facial expressions. The experiment was done by testing the boys and girls using a test constructed with several photos of different facial expressions.

Hypothesis

The girls will be able to identify the facial expressions more accurately than the boys.

Scientific Terms

Facial expression, communication

Background

Facial expression

Facial expression is a form of non-verbal communication where the movement of the muscles and skin on the face are able to convey certain emotions to an onlooker or observer. Examples of facial expressions that are normally encountered are faces of happiness, anger, worry, surprise, fear and sadness. The significance and meanings of facial expressions may vary among different cultures and ethnic groups.

Some facial expressions are made voluntarily to express or convey a certain message to the observer. An example of this behavior is when we greet someone with a smile, or frown to express our disapproval. However, most of the time, facial expressions are involuntary and are triggered by an emotional response to an event. In such cases, even if we try to hide it, a brief change in facial expression will normally occur before we are able to eventually control or alter the expression.

Facial expressions are also useful for the perceiver because it will enable her to know if something is disturbing or upsetting a person. They provide clues to a person’s true feelings, and may act as a hint to the perceiver to react accordingly.
