Why Are Causal and Temporal Connectives Difficult to Understand? A Comparison Between Italian Hearing Good and Poor Comprehenders and Deaf Poor Comprehenders.

The results suggest that despite a similar reading profile, DHH PCs' difficulties with causal connective understanding are more closely related to their vocabulary delay, whereas hearing PCs' difficulties are more strongly influenced by their poor text integration processes (as indexed by their reading comprehension skills). Neither vocabulary knowledge nor reading comprehension skills contributed to the explanation of DHH readers and hearing PCs' temporal connective understanding.
