We examined sources of morphological variability in second language (L2) learners of Spanish whose native language (L1) is English, with a focus on L1-L2 similarity, morphological markedness, and knowledge type (receptive vs. expressive). Experiment 1 uses event-related potentials to examine noun-adjective number (present in L1) and gender…

Studies of American Sign language including functional magnetic resonance imaging of deaf signers confirms the importance of left hemisphere structures in signed language, but also the contributions of right hemisphere regions to sign language processing. A case study involving cortical stimulation mapping in a deaf signer provides evidence for…

This study examined the effect of emotional content on the verbal pragmatic aspects of discourse production in right-brain-damaged (RBD), left-brain-damaged (LBD), and normal control adults. In the nonemotional conditions, LBDs were particularly impaired in pragmatics, whereas in the emotional condition, RBDs demonstrated pragmatic deficits.…

Brainstem auditory evoked response latencies were studied in 80 males (13 with Down's syndrome). Latencies for waves P3 and P5 were shorter for Down's syndrome subjects, who also showed a different pattern of left versus right ear responses. Results suggest decreased lateralization and receptive and expressive language ability among people with…
