The present study explores the role of cognitive reserve, executive functions, and working memory (WM) span, as factors that might explain training outcomes in cognitive status. Eighty-one older adults voluntarily participated in the study, classified either as older adults with subjective cognitive decline or cognitively intact. Each participant underwent a neuropsychological assessment that was conducted both at baseline (entailing cognitive reserve, executive functions, WM span and depressive symptomatology measures, as well as the Mini-Mental State Exam regarding initial cognitive status), and then 6 months later, once each participant had completed the training program (Mini-Mental State Exam at the endpoint). With respect to cognitive status the training program was most beneficial for subjective cognitive decline participants with low efficiency in inhibition at baseline (explaining a 33% of Mini-Mental State Exam total variance), whereas for cognitively intact participants training gains were observed for those who presented lower WM span.

Object-relative clauses are generally harder to process than subject-relative clauses. Increased processing costs for object-relatives have been attributed either to working memory demands for the establishment of long-distance dependencies or to difficulties processing unexpected, noncanonical structures. The current study uses self-paced reading to contrast the impact of both kinds of factors in Spanish object-relative clauses, manipulating the interposition of the subject of the relative clause between object and verb. In addition, object-relatives were unambiguously marked at their onset with the Spanish preposition "a". Reading times increased at the onset and final regions of object-relative clauses, regardless of interference-based working memory costs, although interference costs may affect the processing of post-relative-clause regions. These results suggest that, beyond interference-related working memory costs, end-of-clause integration processes may be affected by a preference for canonical structures, thus increasing processing difficulties when confronted with a noncanonical form.

This study explores morpho-syntactic reading comprehension in 19 Spanish children who received a cochlear implant (CI) before 24 months of age (early CI [e-CI]) and 19 Spanish children who received a CI after 24 months (late CI [l-CI]). They all were in primary school and were compared to a hearing control (HC) group of 19 children. Tests of perceptual reasoning, working memory, receptive vocabulary, and morpho-syntactic comprehension were used in the assessment. It was observed that while children with l-CI showed a delay, those with e-CI reached a level close to that which was obtained by their control peers in morpho-syntactic comprehension. Thus, results confirm a positive effect of early implantation on morpho-syntactic reading comprehension. Inflectional morphology and simple sentence comprehension were noted to be better in the e-CI group than in the l-CI group. The most important factor in distinguishing between the HC and l-CI groups or the e-CI and l-CI groups was verbal inflectional morphology.
