Bound and referential pronouns - Cognitive Science

Interpreting pronouns
When the interpretation of a pronoun depends on another DP
this may be due to
i. the pronoun being c-commanded and syntactically bound
by that DP.
We speak here of bound pronouns (in a narrow sense of
"bound").
This relation is obviously only possible within a sentence
and is not based on a relation of reference.
(1) John thought he would be late.
(2) Everyone thought he would be late.
(3) Fred told Jane she would be late.
Interpreting pronouns
When the interpretation of a pronoun depends on another DP,
this may, alternatively, be due to
ii. the pronoun occurring referentially,
a. referring to the same entity that is referred to by
another referential DP in discourse (strict
coreference)
(4) John took the train. He went to Berlin.
b. or referring to an entity that was introduced into the
discourse indirectly by another, not necessarily
referential, DP (discourse reference)
(5) A man called. But he didn't leave a message.
(6) John wanted to catch a fish. He wanted to eat it
for dinner.
