Note. vSTM – verbal short term memory (digit span); Sub CE – Subject Center-embedded relative clauses, Obj CE – Object Center-embedded, Sub RB – Subject Right-branching, Obj RB – Object Right-branching. The values represent average accuracy scores; % correct responses are given in parentheses.
c
– performance not significantly different from chance based on a set of 2-tailed one-sample t-tests performed separately for each group and condition.
bc
- performance below chance.
