    Study Notes

    Introduction to Nonverbal Communication

    • Interpersonal effectiveness relies on more than just words
    • Nonverbal cues either enhance or detract from verbal communication
    • People become the message, communicating their state of mind, expectations, and self-perception through nonverbal cues
    • Constant nonverbal communication reveals underlying feelings and thoughts

    Definition of Nonverbal Communication

    • Nonverbal communication utilizes nonlinguistic methods
    • It encompasses actions, physical attributes, use of objects, sounds, time, scents, and space conveying socially shared meaning
    • Includes visual/kinesic factors (facial expressions, eye movements, gestures, body postures), vocal/paralinguistic factors (volume, pitch, rate, inflection), proxemic cues (space and distance), olfactory cues (smell), and cues through objects and appearance.
    • Coined in 1956 by Jurgen Ruesch and Weldon Kees in "Nonverbal Communication: Notes on the Visual Perception of Human Relations"

    Nonverbal Communication's Role in Message Delivery

    • Nonverbal cues contribute significantly (roughly two-thirds) to the overall message value
    • Nonverbal signals alone can communicate effectively independent of words, if they are understandable to an observer
    • The clarity and receptiveness of the observer impacts the message's significance

    Categories of Nonverbal Communication

    • Kinesics: Body language
    • Personal Appearance
    • Physical Environment
    • Proxemics: Space and distance
    • Haptics: Touch
    • Vocalics: Voice characteristics
    • Chronemics: Time

    Functions of Nonverbal Communication

    • Contradict or negate verbal messages
    • Emphasize or underscore verbal messages
    • Regulate or control interactions
    • Reinforce or complement verbal messages
    • Substitute for spoken words

    History of Nonverbal Communication

    • Humans' development throughout history was challenged by various environmental, social, economic, and psychological obstacles.
    • Ancestors used nonverbal communication for survival and socialization before complex vocal abilities developed

    Biological Evolution of Nonverbal Communication

    • Biological evolution encompasses anatomical and physical changes
    • Brain size increased gradually from great apes to Homo sapiens through Homo Habilis to Erectus and finally to Sapiens
    • Brain lobe expansion and anatomical changes support development of cognitive skills (language, judgment, and sexual behavior), including speech production

    Brain Volume and Gyri

    • Great apes have smaller brain volumes than the Homo genus (400-500 cm³ vs 1000 cm³ or more)
    • Brain gyri (foldings) increase brain surface area, furthering cognitive development and function. The increased size of the neocortex supported speech production and language
    • Brain volume and gyri correlation is associated with increased complexity, hence with intelligence

    Brain-Body Ratio

    • Ratio of brain size to body size is not a direct measure of intelligence
    • Higher brain-body ratio in Homo Sapiens may indicate a higher IQ potential relative to earlier hominids, though it isn't a definitive correlation.

    Body Structure

    • Spine Structure: Emergence of the lumbar curve in Homo species is key for bipedalism
    • Foot Evolution: Increased foot length and heel size for enhanced balance and support in bipeds
    • Hand Evolution: Developments in hand structure enabled more diverse tasks due to increased dexterity

    Facial Features Evolution

    • Changes in jaw and facial structures played a significant role in the evolution of human communication. Changes to the size and shape of the jaw and face, influenced speech development and allowed Homo to use tools to modify and process more digestible food.
