Nonverbal communication

From PsychEvos Wiki


Nonverbal communication is the sharing of information, feelings, or ideas through non-verbal cues, using a combination of facial expressions, gestures, body posture or position, and other visual or auditory signals. This form of communication can occur in various contexts, including psychology, animal behavior, and in the context of interpersonal relationships between humans[1]. Nonverbal communication has its roots in evolutionary biology, as it has been suggested that many of these behaviors are instinctive and have evolved over time to facilitate important aspects of communication and interaction in social species[2].

Categories of nonverbal communication

Nonverbal communication can be divided into several categories, including:

  • Kinesics: This involves body movement, such as facial expressions, gestures, eye contact, and posture, all of which transmit information to others[3].
  • Proxemics: This refers to the use of space and positioning to communicate, including distance between individuals, orientation, and body positions[4].
  • Haptics: This category focuses on the role of touch in communication, including cues like handshakes, hugs, and pats on the back[5].
  • Chronemics: This involves the use of time in communication, such as the timing, duration, or rhythm of interactions[6].

Evolutionary origins of nonverbal communication

Charles Darwin's 1872 publication The Expression of the Emotions in Man and Animals provided a starting point for the scientific study of nonverbal communication and its role in human and animal behavior[7]. Since then, it has been suggested that nonverbal communication may have evolved for several key reasons:

  • Automatic and unconscious cues: Nonverbal cues can be produced without conscious effort, which may have helped early humans to survive and reproduce by allowing them to rapidly convey and interpret potentially vital information without having to think about it[8].
  • Emotional expression: Nonverbal communication can convey emotions and feelings, which may help to establish bonds and relationships within social groups, thus promoting the cooperative behaviors that enhance survival and reproduction opportunities[9].
  • Facilitation of verbal communication: Nonverbal cues can supplement, modify, or reinforce verbal communication, providing additional context to spoken language and making it more efficient and effective in conveying information[10].

Applications of evolutionary psychology in studying nonverbal communication

The framework provided by evolutionary psychology can help to guide researchers in studying nonverbal communication by suggesting hypotheses about the adaptive functions of specific nonverbal behaviors and examining how they may have shaped human communication in modern times[11]. For example, the study of facial expressions can be approached from an evolutionary perspective by examining whether these cues are universal across cultures and whether they can be linked to functional or adaptive outputs[12].


Nonverbal communication is a fundamental aspect of human interaction, encompassing various behaviors, such as kinesics, proxemics, haptics, and chronemics, that transmit information between individuals. Evolutionary psychology provides a useful framework for understanding the adaptive functions and origins of these behaviors, shedding light on how they may have evolved in response to the need for effective communication in social species. By applying the principles of evolutionary psychology to the study of nonverbal communication, researchers can gain valuable insights into the underlying reasons for the development and persistence of these behaviors in modern humans.
