Language and Communication: Fundamentals, Process, and Components

Concept and Fundamentals of Communication

• Definition of Communication: Communication is a dynamic process of interaction between individuals of the same community, consisting of the exchange of experiences related to objective reality or internal subjective reality. Every act of communication represents an added experience that enriches the reality of the involved individuals.
• Communication in the Animal Kingdom:
  • Communication is not exclusive to humans; animals from insects to birds utilize complex communication systems vital for survival.
  • As an animal occupies a higher position on the evolutionary scale, its sensory organs become more complex, and its mechanisms for signal production become more elaborate.
  • Primary functions of animal communication include reproduction, territorial and hierarchical delimitation, and information transmission.
• Distinction Between Communication and Information:
  • Information: Consists of providing data and placing it at the public's disposal, without concern for whether the recipient actually receives or understands it.
  • Communication: Requires that the recipient successfully captures and decodes the message, creating a mutual exchange.
• Modes of Communication: Communication can occur through sounds, mimicry, gestures, and facial expressions, with speech being the most specific and essential mechanism of human communication.

The Communicative Process and Its Essential Elements

• Definition of the Communicative Process: A sequence of structured acts through which communication becomes effective among two or more individuals.
• Minimum Requirement: Communication requires a minimum of two interlocutors (sender and receiver) exchanging a message through a channel within a specific context.

• Key Elements:
  • Sender (Emisor): The individual who emits a message with a specific purpose, choosing, selecting, and combining signs to formulate it (the process of encoding or codificación).
  • Receiver (Receptor): The individual who receives and decodes the message.
  • Code (Código): A system of signs and rules used to formulate and comprehend messages. Effective communication requires sender and receiver to share the same code.
    • Linguistic Code: Verbal language (spoken or written across different human languages) and non-verbal linguistic codes (such as Sign Languages / Lenguas de Signos).
    • Non-Linguistic Code: Codes operating within non-verbal communication.
  • Message (Mensaje): The informational content conveyed by the sender, formed by a conscious and complex combination of code signs, decoded by the receiver.
  • Channel (Canal): The physical medium through which the message travels.
    • Noise (Ruido): Any interference or disturbance in the channel that degrades, alters, or impairs message quality and reception.
  • Context (Contexto): The overall set of circumstances and environment in which communication occurs, encompassing physical, emotional, and situational settings.

Communicative Intentionality and Feedback

• Communicative Intentionality: The sender always emits a message with a specific intent (e.g., sharing data, attracting interest, making a request). This intentionality is mandatory for genuine communication and seeks to provoke a response in the receiver.
• Feedback (Retroalimentación): Ensures communication is a bilateral process. The receiver interprets the message, generates a response, and transforms into a sender, establishing continuous two-way interaction.

Elaboration and Emission of Messages: Verbal and Non-Verbal Components

• Integration of Components: Messages integrate both verbal and non-verbal components to yield complete communicative meaning.

• Classification Matrix of Communication Elements:
  • Vocal + Verbal: Spoken verbal language (Lenguaje verbal hablado).
  • Vocal + Non-Verbal: Paralanguage (Paralenguaje).
  • Non-Vocal + Verbal: Written verbal language (Lenguaje verbal escrito).
  • Non-Vocal + Non-Verbal: Kinesics (Kinesia) and Proxemics (Proxemia).
• Verbal Components: Refers to words used in spoken or written forms, governed by grammatical, semantic, psychological, sociocultural, and pragmatic rules.
• Non-Verbal Components: Non-word signs or signals with communicative capability, often expressed unconsciously, which express genuine feelings and emotions.
• Paralanguage (Non-Verbal Vocal):
  • Tone of Voice: Modulates meaning; an improper tone can confuse the listener.
  • Rhythm: Provides clues regarding emotional state and pacing.
  • Volume: Reflects intensity, highlights emphasis, and reveals speaker traits.
  • Silences: Pauses and silences that convey specific information.
  • Timbre: The distinct vocal quality unique to each individual.

Kinesics, Proxemics, and Body Language Theories

• Kinesics (Kinesia): The study of body language, including gestures, body movements, facial expressions, smiling, eye contact/gaze, and posture.
• R.L. Birdwhistell's Principles of Kinesics:
  • Coined by American researcher R.L. Birdwhistell, who asserted that words account for only $35\%$ of meaning in conversation, leaving the remaining $65\%$ to non-verbal signals.
  • Principle 1: No body expression is devoid of meaning within its context.
  • Principle 2: Posture, body movement, and facial expressions are typified and can be systematically analyzed.
  • Principle 3: Body language functions as a social system within a community.
  • Principle 4: Visible bodily activity systematically influences the behaviors of others in a group.
  • Principle 5: Body behavior is assumed to carry communicative function unless proven otherwise.
  • Principle 6: No single body posture or movement holds absolute meaning by itself; it only gains exact meaning within the context of an individual's overall conduct pattern.
• Proxemics (Proxemia):
  • Refers to personal spatial distance required for effective communication.
  • Depends on interpersonal trust, personality, type of encounter, age, and culture.
  • Excessive Distance: Creates an impersonal atmosphere that prevents warm communication.
  • Excessive Proximity: Perceived as an invasion of personal space, particularly in professional contexts, provoking rejection.

Distinction Between Language, Specific Language, Speech, and Writing

• Language (Lenguaje): The universal human capacity and symbolic, structured code of signs used to translate thought into expressible form. It is common to all human beings.
• Specific Language / Tongue (Lengua): A specific system of oral and written signs adopted by a particular linguistic community. It is a changing, dynamic structure that evolves over time across geographic or social distributions.
• Speech (Habla): The concrete, observable, physical, and subjective execution of a language by an individual at a specific moment. Speech varies across individual speakers.
• Writing (Escritura): The graphic representation of a language's sign system.

Functions of Language: Communicative and Symbolic

• Core Dual Functions: Language fulfills two primary functions: communicative (message elaboration/emission) and symbolic (thought processing and mental representation).
• Communicative Subfunctions:
  • Instrumental Function: Demanding or requesting to satisfy personal needs or desires.
  • Regulatory Function: Controlling or directing the behavior of self and others through commands and orders.
  • Interactional Function: Establishing social relationships with others.
  • Personal Function: Expressing self-affirmation, emotions, tastes, and preferences.
  • Heuristic Function: Asking questions to gain knowledge about the environment.
  • Imaginative Function: Creating, playing, and expressing imaginary or creative realities.
  • Informative Function: Explaining, describing, or stating facts and information.
• Symbolic Function:
  • The capacity to use symbols to represent objects, ideas, or concepts.
  • Jean Piaget's Model: The symbolic function enables the representation of a signified concept (significado) through a differentiated signifier (significante) dedicated to that representation.
  • Establishes a link between thought and language, organizing mental structures as language evolves.
  • Clinical Relevance: Understanding symbolic function is critical when implementing augmentative or alternative communication systems for children with communication impairments.

Anatomical, Functional, and Brain Bases for Language Acquisition

• Evolutionary Progression: Human evolution shifted communication from inarticulate primate cries to complex, articulated sound sequences structured by morphosyntactic rules.
• Auditory System (Sensory Processing):
  1. Sound waves travel through air, enter the outer ear (pinna and external auditory canal).
  2. Sound strikes the tympanic membrane, converting acoustic waves into mechanical vibrations.
  3. Vibrations move the middle ear ossicles.
  4. Inner ear cochlea receptors convert mechanical vibrations into nerve impulses.
  5. Impulses travel via the auditory nerve to brain areas for decoding and interpretation.
• Brain Structures in Oral Communication:
  • Wernicke's Area: Responsible for decoding messages, connecting heard words to semantic meanings, and comprehending phonemes.
  • Broca's Area: Responsible for encoding language, message construction, and converting linguistic ideas into motor impulses sent to phonoarticulatory structures.
  • Luria's Area (Motor Areas): Controls movement execution across phonoarticulatory organs.
  • Complementary Areas: Support symbolization, cognitive synthesis, and memory.
• Phonoarticulatory / Bucophonatory System:
  • Respiratory System: Airways and lungs supplying controlled air currents.
  • Vibratory Organ: Larynx containing vocal cords that vibrate as air passes through.
  • Articulatory Organs: Teeth, lips, hard palate, soft palate, velum, and tongue shaping vocal vibration into distinct words.
  • Resonance Cavities: Nasal cavities, mouth, and stomach area.

Essential Intrinsic and Extrinsic Conditions for Language Development

• Intrinsic Conditions:
  • Optimal Intelligence Level: Intellectual capability influences symbolization, acquisition rate, and linguistic progression.
  • Physiological Maturity: Functional development of sensory, nervous, and phonoarticulatory structures.
• Extrinsic Conditions:
  • Adequate Environmental Stimulation: Motivational adult interactions and frequent verbal exposure.
  • Imitation Processes: Availability of proper communication models for children to emulate.
  • Interaction Processes: Shared activities with others; learning to interact fosters learning to speak.

Levels of Linguistic Analysis and Components of Language

• Semantics: Studies the meanings of words and expressions (content level), including historical vocabulary changes.
• Phonology and Phonetics: Studies speech sounds. Phonology addresses acoustic features (clarity, intonation, pauses, rhythm); Phonetics addresses physiological articulation.
• Morphosyntax:
  • Morphology: Studies sound combinations into morphemes, addressing grammatical gender, number, and verb tenses.
  • Syntax: Studies word ordering rules within sentences and sentence relationships within discourse.
• Pragmatics: Studies speaker intent within specific contexts, incorporating irony, sarcasm, double meanings, and community idioms. Pragmatics is complex because literal semantic meaning frequently differs from intended communicative message.

Hierarchical Organization of Language Units

• Phoneme (Fonema): Minimal distinctive unit lacking meaning. The Spanish phonological system contains $24$ phonemes represented by $27$ letters.
• Morpheme / Moneme (Monema): Smallest meaningful unit resulting from phoneme combinations, forming internal word structure.
• Word (Palabra): Minimal separable unit in speech conveying meaning, serving as a core of meaning, function, and pronunciation.
• Sentence (Oración): Rule-governed arrangement of words (traditionally subject + predicate) expressing complete thought.
• Discourse (Discurso): Articulation of multiple coherent sentences forming a unified text or speech.
