8.11 Introduction to Language and Phonemes

Introduction to Language

  • Language is multifaceted and complex, encompassing both motor and cognitive perspectives.

    • Involves fine motor control of lips and mouth for sound production.

    • Requires complex computational processes in the brain for constructing sentences that are understandable.

Definition of Language

  • Language is a communication system that utilizes symbols combined according to rules.

    • Can manifest in multiple formats:

    • Spoken language (e.g., verbal communication)

    • Written language (e.g., text on slides)

    • Gestural language (e.g., American Sign Language)

Philosophical Debate on Human Language

  • There is significant debate regarding whether human language possesses unique features compared to animal communication.

    • Key Points Supporting Uniqueness:

    • Semanticity:

      • The sounds of words have arbitrary connections to their meanings.

      • Example: The word "dog" signifies that particular animal due to collective agreement on its representation, not due to any inherent quality of the sound made.

      • Different languages may denote the same concept with entirely different sounds (e.g., the word for dog varies across languages).

    • Productivity:

      • Human language allows the creation of an infinite variety of meanings through new constructions of words and sentences.

      • Example: A speaker can to construct a sentence that has never been said before, yet still be understood due to shared language rules.

    • Displacement:

      • The ability to communicate about things beyond the immediate moment or location.

      • Enables discussions about the past and future or abstract concepts not anchored in the present.

    • Social Learning:

      • Human language is acquired through social interaction and exposure during formative years.

      • A lack of exposure may result in atypical language development, unlike some animal communication systems which can develop vocalizations independently of social teaching.

Components of Language

  • Understanding language involves analyzing its smallest components, known as phonemes.

    • Phonemes: Basic units of speech that the human vocal tract can produce, approximating 200 distinct phonemes.

    • Individual languages, such as English, utilize only a subset of these phonemes (approximately 44 for English).

    • Example: The word "bat" contains three phonemes:

      • b (voiced bilabial plosive)

      • a (open back unrounded vowel)

      • t (voiceless alveolar plosive)

Development of Phonemic Awareness

  • Newborns can differentiate all phonemes; as they mature, they specialize in the phonemes of their native languages.

  • By age 10, children may lose the ability to hear subtle differences between certain phonemes from different languages.

  • Language barriers often arise when communicating with non-native speakers due to specialized phonemic awareness.

    • Example of Language Barrier:

    • Discussing the French author "Albert Camus":

      • Mispronunciation as "Albert Camus" was flagged by a French friend as incorrect, noting the distinct pronunciation of certain phonemes in French that are less distinguishable in English.

  • Development of specific phonemes, such as the English "r" sound, can vary:

    • Typically mastered around ages 6-7.

    • May be delayed in speech development compared to other phonemes.
