Under-developed awareness of social cues can make interaction in social situations challenging. There are various mental disorders (e.g. schizophrenia) that impair this ability, and therefore make effective communication as well as forming relationships with others difficult for the affected person. Additionally, research shows that older adults have difficulties in extracting and decoding social cues from the environment, especially those about human agency and intentionality. Children rely more on social cues than adults as children use them in order to comprehend and learn about their surroundings. Examples of social cues Nonverbal cues Facial cues Facial expressions are signals that we make by moving our facial muscles on our face. Facial expressions generally signify an emotional state, and each emotional state and/or state of mind has a specific facial expression, many of which are universally used around the world. Without seeing someone's facial expression, one would not be able to see if the other person is crying, happy, angry, etc. Furthermore, facial expressions enable us to further comprehend what is going on during situations that are very difficult or confusing. Facial cues do not only refer to explicit expressions but also include facial appearance. There is a wealth of information that people gather simply from a person's face in the blink of an eye, such as gender, emotion, physical attractiveness, competence, threat level and trustworthiness. One of the most highly developed skills that humans have is facial perception. The face is one of the greatest representations of a person. A person's face allows others to gain information about that person, which is helpful when it comes to social interaction. The fusiform face area of the human brain plays a large role in face perception and recognition; however, it does not provide useful information for processing emotion recognition, emotional tone, shared attention, impulsive activation of person knowledge and trait implications based on facial appearance. The fallacy of making inferences about people's personality traits from their facial appearance is referred to as overgeneralization effect. For instance, baby face overgeneralization produces the biased perception that people whose facial features resemble those of children have childlike traits (e.g. weakness, honesty, need to be protected); and an attractive face leads to judgements tied to positive personality traits such as social competency, intelligence, and health. It is mainly facial features which resemble low fitness (anomalous face overgeneralization), age (baby face overgeneralization), emotion (emotion face overgeneralization) or a particular
