Answer:
Phrase Structure.
Step-by-step explanation:
It is noted according to research that experiments of this form were used to determine how adults could use their knowledge of grammar to break sentence in sub functions.
Here, it was assumed that these probabilities measured the extent to which adjacent words were independent events during learning. Words from the same functional subunit should be dependent events and those from different subunits should be relatively independent of one another. If Ss break the sentences into subunits using their grammar, the conditional probability of an error should be high between subunits and low within subunits.
