At the time, the majority of the scientific community disagreed with this theory. Ekman believed that expressions were socially learned, and therefore culturally variable. For instance, if you were born and raised in America, you would display very different facial expressions of emotion than if you grew up in Asia. He would then ask the groups to judge what emotion they thought was being displayed in each photograph. The vast majority of the individuals from the five cultures agreed.

The Understanding of the Emotional Meaning of Facial Expressions in People with Autism
Facial expressions are used by humans to convey various types of meaning in various contexts. In this mini review we summarize findings on the use and acquisition of facial expressions by signers and present a unified account of the range of facial expressions used by referring to three dimensions on which facial expressions vary: semantic, compositional, and iconic. Humans perceive facial expressions as conveying meaning, but where do they come from and what exactly do they mean? Based on observations of facial expressions typically associated with emotions Darwin hypothesized that they must have had some instrumental purpose in evolutionary history. For example, lifting the eyebrows might have helped our ancestors respond to unexpected environmental events by widening the visual field and therefore enabling them to see more. Even though their instrumental function may have been lost, the facial expression remains in humans as part of our biological endowment and therefore we still lift our eyebrows when something surprising happens in the environment whether seeing more is of any value or not. Following this tradition Ekman , claimed that there is a set of facial expressions that are innate, and they mean that the person making that face is experiencing an emotion; i.
What mechanisms underlie facial expression recognition? A popular hypothesis holds that efficient facial expression recognition cannot be achieved by visual analysis alone but additionally requires a mechanism of motor simulation — an unconscious, covert imitation of the observed facial postures and movements. Here, we first discuss why this hypothesis does not necessarily follow from extant empirical evidence. Next, we report experimental evidence against the central premise of this view: we demonstrate that individuals can achieve normotypical efficient facial expression recognition despite a congenital absence of relevant facial motor representations and, therefore, unaided by motor simulation.
This research aims to contribute to the literature on the ability to recognize anger, happiness, fear, surprise, sadness, disgust and neutral emotions from facial information. For this purpose, a group of year-old children was selected. Participants were asked to recognize emotions by using a labeling task with three stimulus types region of the eyes, of the mouth, and full face. The findings seem to indicate that children correctly recognize basic facial expressions when pictures represent the whole face, except for a neutral expression, which was recognized from the mouth, and sadness, which was recognized from the eyes. Children are also able to identify anger from the eyes as well as from the whole face. With respect to gender differences, there is no female advantage in emotional recognition.
