Due to our social nature, humans rely heavily on the ability to understand other peoples' mental states and make predictions about their behaviour.
Taking into account other people's internal states such as thoughts or emotions[clarification needed] is a critical part of forming and maintaining relationships.
Being able to accurately detect both positive and negative cues allows one to behave adaptively and avoid future rejection, which therefore produces greater social inclusion.
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.
[8] Additionally, research shows that older adults have difficulties in extracting and decoding social cues from the environment, especially those about human agency and intentionality.
This type of fast, automating processing is often referred to as intuition and allows us to integrate complex multi-dimensional cues and generate suitable behaviour in real time.
Benjamin Straube, Antonia Green, Andreas Jansen, Anjan Chatterjee, and Tilo Kircher found that social cues influence the neural processing of speech-gesture utterances.
When it came to abstract speech and gestures, the left frontal gyrus would be activated according to Straube et al. After conducting an experiment on how body position, speech and gestures affected activation in different areas of the brain Straube et al. came to the following conclusions: The amygdala, fusiform gyrus, insula, and superior and middle temporal regions have been identified as areas in the brain that play a role in visual emotional cues.
Higher level visual regions, such as the fusiform gyrus, extrastriate cortex and superior temporal sulcus (STS) are the areas of the brain which studies have found to link to perceptual processing of social/biological stimuli.
Behavioral studies have found that the right hemisphere is highly connected with the processing of left visual field advantage for face and gaze stimuli.
The results of Greene and Zaidel's study suggest that in relation to visual fields, information is processed independently and that the right hemisphere shows greater orienting.
The connection between the amygdala, OFC, and other medial temporal lobe structures suggest that they play an important role in working memory for social cues.
Systems which are critical in perceptually identifying and processing emotion and identity need to cooperate in order to maintain maintenance of social cues.
After coming across the same person multiple times with different social cues, the right lateral orbitofrontal cortex and hippocampus are more strongly employed and display a stronger functional connection when disambiguating each encounter with that individual.
During an fMRI scan the lateral orbitofrontal cortex, hippocampus, fusiform gyrus bilaterally showed activation after meeting the same person again and having previously seen two different social cues.
There have been findings that oxytocin increases occurrence of attention shifts to the eye region of a face which suggests that it alters the readiness of the brain to socially meaningful stimuli.
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.
The fusiform face area of the human brain plays a large role in face perception and recognition; however, it does not provide useful information[further explanation needed] for processing emotion recognition, emotional tone, shared attention, impulsive activation of person knowledge and trait implications based on facial appearance.
[20] 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 that the attractive person possesses positive personality traits such as social competency, intelligence, and health.
Infants that are already 12 months old respond to the gaze of adults, which indicates that the eyes are an important way to communicate, even before spoken language is developed.
Guellai and Steri concluded that at birth, babies are able to read two forms of social cues: eye gaze and voice.
An important social cue that helps children comprehend the function and meaning of a sign or symbol[clarification needed] is an engaging facial expression.
[clarification needed] Smith and LaFreniere mention recursive awareness of intentionality (RAI), which is the understanding of how the cues one provides will influence the beliefs and actions of those receiving them.
Sometimes when students are stuck in a previous discussion or cannot determine an appropriate response to the current topic, it could mean that they did not correctly perceive the cues that the teacher was displaying.
[38] The main social cue impairments of those on the autism spectrum include interpreting facial expressions, understanding body language, and deciphering gaze direction.
However, research has found that autistic children and adults have no difficulty in identifying human bodily movements or body language that is used in everyday and normal activities.
The aspect that autistic people have trouble with is more so the ability that is needed to verbally describe the emotions that are connected with these types of bodily movements.
A false positive is made whenever a participant mistakenly believes that they observed a specific social cue in the vignette shown to them.
[49] However, others have suggested that whether or not the reduced availability of social cues results in negative behavior may depend upon the situation and the individual's goals.
[47] A positive feature of the internet is that it hosts millions of different chat rooms and blogs that allow people to communicate with others who share the same interests and values.
