examples of nature VS nurture Flashcards
the holy roman emperor (Fredrick Barbarossa) in 1200s
he wanted to discover what lang adam and eve spoke, so took a set of male and female twins to be isolated and completely deprived of hearing any speech, to see what lang they would grow up speaking. the C never learnt to speak, suggesting it’s nurture as they where never taught
Victor of Avegron in 1299
abandoned until he was 12 years old and then found and raised caringly and sent to a school for the Deaf in Paris. he never learnt to speak, showing that nurture couldn’t recover his inability to speak
Oxana Malaya
abused by alcoholic parents and lived in a dog kennel until she was 7, she ate dog food and barked and was cared for by the dogs. at 7, she was alinguistic, but she was adopted and managed to develop full lang abilities. nurture recovered her speech
Bard and Sach’s study of Jim
Jim had deaf and mute parents. his parents raised him lovingly and wanted Jim to be able to speak, so they surrounded him with broadcasted speech, from the Tv/radio. by 5, Jim had no language abilities, but he was put into speech therapy at this age and by 6 was able to speak as well as the average 6 year old. this suggests that broadcasted speech is useless, and language has to be directly heard
Suriname Creole
escaped slaves who all spoke different languages managed to create a fully functioning creole within one generation. nature as this appears to be a built-in ability
the Tsimane tribe
tribe in Bolivia who do not speak to their C/use any CDL until they say their first word, then they are directly spoken to. C in this tribe tend to say their first word at the age of 5 (normal age is 9 months), and then by 6 (when they have been directly spoken to) they have the normal/expected language abilities of a 6 year old. these C have delayed speech learning
