Yes, though I would suggest that 17 and 18 year olds everywhere in Florida are developmentally ready to study psychology, except perhaps in extreme cases of developmental delay caused by disability. The situation here is really not that late teens would be harmed by studying psychology, but that a fringe minority of Christian extremists don't want them to study psychology - or at least not study psychological findings about trans and gay people -- which these extremists disagree with, not based on data and evidence, but on their religious superstitions.
