New Symbols
Premack was able to demonstrate that Sarah could understand how to decode a symbol stream after training. First she had to learn the token name-of and then learn that some new, but real objects had the name-of fig token1 and crackerjack token2.
She learned
- Real fig name-of fig token1
and
- Real crackerjack name-of crackerjack token2.
She was tested with
- fig token1 "?" Real crackerjack
which she answered correctly with
- fig token1 Not name-of Real crackerjack
Finally, with the trainer placing a ripe fig on the table, and the tokens fig token1, crackerjack token2, give, Mary, Sarah, orange, banana, Sarah produced the new sentence
- Mary give fig token1 Sarah
and with the trainer placing a crackerjack on the table, Sarah produced the new sentence
- Mary give crackerjack token2 Sarah

Famous quotes containing the word symbols:
“There are those who would keep us slipping back into the darkness of division, into the snake pit of racial hatred, of racial antagonism and of support for symbols of the struggle to keep African-Americans in bondage.”
—Carol Moseley-Braun (b. 1947)
“Children became an obsessive theme in Victorian culture at the same time that they were being exploited as never before. As the horrors of life multiplied for some children, the image of childhood was increasingly exalted. Children became the last symbols of purity in a world which was seen as increasingly ugly.”
—C. John Sommerville (20th century)
