Even though redundancy does increase reading times, matching i and j may still require relatively little cognitive effort when both i and j share a large number of properties (or words) if compared to matching a more dissimilar description pair.
we hypothesize that for a closely-related pair of descriptions (i.e., an anaphor and a c1 object, or an anaphor and the actual antecedent term) the readers may benefit from some form of shallow processing to quickly decide, for example, that the reference "the small black cat" is not the same as (c1) "the small white cat", but that it does co-refer with an antecedent term "the black cat".
