Animal Communication vs. Human Language

  • The idea that animals like insects and dogs might have their own form of language through behaviors like dancing or barking.
  • Example of domestic dogs: Communicate through specific sounds, tail wagging, and other physical signals, but lack true language complexity.
  • Example of chimpanzees: Have been known to use sign language to communicate, showcasing advanced communication skills.

The Unique Nature of Human Language

  • Importance of distinguishing between communication and true language.
  • Example of a demonstration: A volunteer was asked to communicate needs without words, highlighting the complexity of human language.

Characteristics That Define Human Language

  • Despite evidence of communication in animals, human language has unique characteristics that set it apart.

Language Facts

  • Deaf children not exposed to sign language create their own versions,
    • Develop symbols and signs for various concepts (nouns, verbs, adjectives).
  • Language usage remains coherent despite spelling and grammatical variations (e.g., emails with grammar check errors).
  • All cultures have a language, showing a universal aspect of human societies.

Linguistic Universals of Human Language

  • Significant features that are present in all human languages:
    1. Semanticity: Language conveys meaning by attaching words to concepts.
    • Example: "Apple" represents a specific fruit, demonstrating societal shared knowledge about meanings.
    1. Arbitrariness: No inherent connection between a word and its meaning.
    • Example: The word "apple" has no logical connection to the object it denotes across different languages.
    1. Flexibility in Naming: Words can evolve over time.
    • Example: Words like "woke" and "gay" have changed in meaning over the years.
    1. Displacement: Ability to discuss things not immediately present in time or space.
    • Example: Talking about future plans or past events.
    1. Productivity: Capacity to create new messages using existing elements of language.
    • Example: Nonsense sentence by a linguist: "Colorless green ideas sleep furiously."

Phonemes and Morphemes

Phoneme

  • Basic sound unit in language; smallest segment that alters meaning.
    • English contains 47 phonemes instead of 26 letters, due to different sounds that can arise from the same letter.
    • Example: Changing "b" to "f" in "buck" creates a completely different meaning.
    • Certain languages, like Hawaiian, have fewer phonemes (11) but longer words to convey meanings.

Morpheme

  • Smallest meaningful unit of language.
    • Example: "School," "good," or suffixes like "-ness" or prefixes like "pre-."
    • Different morphemes can change the meaning of a root word.
    • Example: "Chimp" vs. "chimps" (adding "s" indicates plurality).

Importance and Study of Language Components

Phonology

  • Study of speech sounds (phonemes) and their organization in human languages.
    • Example: Relationship between sounds in pronunciation and accents (cultural variations).

Syntax

  • Structure of sentences, including grammar rules determining the order of words.
    • Syntax provides rules that dictate how sentences are formed grammatically.

Semantics

  • Study of meaning in language and words.
    • Concerned with definitions, context, and how meanings evolve.

Contextual Influences on Language

  • Coarticulation: Anticipation of phonemes affects pronunciation causing blending of sounds.

Applications in Actual Speech

  • Recognition of words can be hindered when context is removed. Example with the parsing experiment:
    • Experiment results show that participants struggled to recognize their own words when cited without context.

Insights from Experiments and Observations

  • Cognitive processing impacts sound and language perception.
    • Top-down processing of language emphasizes the role of context in understanding spoken language.
    • Example: People filling in gaps when they expect certain phrases, such as determining concepts based on context.

Conclusion

  • Key take-home: While many species communicate effectively, human language’s complexity and capacity for abstraction, evolution, and meaningful structure are uniquely sophisticated.
