Study Notes
Animal Language Learning Studies
- Early attempts to teach apes spoken English faced limitations. Furness's orangutan learned "papa" and "cup." The Kelloggs' chimpanzee, Gua, comprehended 95 spoken commands but did not produce speech. Viki, another chimpanzee, learned four poorly pronounced words ("mama," "papa," "up," and "cup"). Researchers noted a difference between Gua's superior comprehension and Viki's limited results , likely due to differing experimental designs. Both studies demonstrated that apes’ speech comprehension exceeds their production, paralleling the stages of human language acquisition in infancy.
- Furness's orangutan project ended with the animal's death after learning only "papa" and "cup".
- The Kelloggs raised a chimpanzee, Gua, and observed that Donald, the child in the experiment, began adopting chimpanzee-like behaviors, ending the study.
Dolphin Language Learning
- Early dolphin studies focused on mimicking human speech. John Lilly's work with Elvar involved forcing air through the blowhole to approximate words ("squirt"). However, pronunciation issues and unsupported claims hampered the study's validity. Lilly's later claims about dolphin intelligence and even religion were unsubstantiated and met with skepticism.
- Later studies, conducted by Herman, used artificial languages. Dolphins Akeakamai and Phoenix learned gesture-based and sound-based artificial languages. They demonstrated comprehension of approximately 30 words and complex commands (e.g., "window tail touch"). They even understood sentences with reversible meanings ("pipe hoop fetch" vs. "hoop pipe fetch").
- Akeakamai learned a gesture-based visual language and Phoenix learned a sound-based language.
- Both understood commands using 2-5 word sequences and syntactically complex sentences.
- They demonstrated comprehension of semantically reversible sentences and could answer "absence questions"
- Dolphins showed comprehension of relational and syntactic structures, including novel combinations of words and responding accurately to novel commands, not just stimulus-response.
Parrot Language Learning
- Pepperberg's research with Alex, an African Grey Parrot, involved teaching him spoken English. Alex's vocabulary exceeded 100 words, including object names, colors, and shapes. He could identify objects by combining multiple attributes, conceptualize categories, and request or refuse items.
- Key insights included his ability to combine characteristics to identify objects, conceptualize categories, and request or refuse items and often displayed human-like phonological errors.
- Alex could conceptualize and generalize attributes (cork, wood, wool) and combine learned categories.
- While Alex exhibited impressive vocabulary and cognitive skills, his understanding of syntax did not surpass rudimentary levels. His communication lacked the complexity of hierarchical or structured grammar.
Dog Language Learning
- Rico, a border collie, demonstrated impressive single-word comprehension and fast-mapping, learning a new word after hearing it once. His vocabulary exceeded 200 words, and he successfully retrieved objects by name.
- Rico lacked the ability to use syntax or combine words into structured sentences, demonstrating a limit comparable to other pets.
Conclusion
- Animal language skills, while impressive in comprehension, are rudimentary compared to human language.
- Comprehension usually exceeded production in studied animals, like apes, dolphins, parrots, and dogs.
- No studied animals displayed grammatical language or syntactic structures similar to human language.
- Theories explaining the difference include the lack of necessary intelligence (pro-intelligence theory) or the absence of a unique human language faculty (innatist theory).
- The fundamental differences in linguistic abilities highlight the unique nature of human language, despite animal communication successes.
