Morphosyntactic Production and Verbal Working Memory: Evidence From Greek Aphasia and Healthy Aging

Conclusions Results suggest that individuals with WM limitations (both PWA and healthy older speakers) show dissociations between the production of verb-related morphosyntactic categories. WM affects performance shaping the pattern of morphosyntactic production (in Greek: subject –verb agreement> tense> aspect). The absence of an effect of locality suggests that executive capacities tapped by WM tasks are involved in morphosyntactic processing of demanding categories even when the cue is adjacent to the target. Results are consistent with the Interpretable Features' Impairment Hypothesis (Fyndanis et al., 2012).Supplemental Materialhttps://doi.org/10.23641/asha.6024428
