Development of logical connectives

[Edilaine Lins Gouveia]

I'm a graduate student at UFPE in Recife, Brazil. I've been collecting
longitudinal speech samples of a young child learning Brazilian
Portuguese. I'm specially interested in the development of logical
connectives (conditionals, negation, disjunction, conjunction, and
quantification). Any relevant articles that have traced the development
and use of logical vocabulary in children's spontaneous speech will be
welcome.

Thank you in advance,

Edilaine
