Perceptual Adaptation

The two experiments described in this paper were designed to investigate further the phenomenon called motor-motor adaptation. In the first investigation, subjects were adapted while noise was presented through headphones, which prevented them from hearing themselves. In the second experiment, subjects repeated an isolated vowel, as well as a consonant-vowel syllable which contained a stop consonant. The findings indicated that motor-motor adaptation is not a product of perceptual adaptation, and it is not a result of subjects producing longer voice onset times after adaptation to a voiced consonant rather than shorter voice onset times after adaptation to a voiceless consonant.

Phonetic Categorization

Discrimination and phonetic identification abilities of 5- to 6-year-old children with language impairments were compared to those of 4-year-olds with normally developing language and to previous findings from 5- to 6-year-olds and adults for synthetic stimuli ranging from [ba] to da]. Results showed similar discrimination sensitivity to the second- and third-formant transition cues of stimuli by all children, with poorest sensitivity by the youngest. Phonetic categorization by children with language impairments was most different from the groups with normal language abilities, evidenced by a difference in the percent of tokens labeled as "BA" and by greater variability in labeling and in placement of phonetic category boundaries. Results support hypotheses by Gathercole and Baddeley (1990) suggesting that the phonological component of working memory may be disordered in children with language impairments. Results are also suggestive of specific difficulties with left-hemisphere processing associated with language learning rather than with problems related to sensitivity to formant transitions of the speech tokens.

Eyes Closed

A subject wore for six days a microphone on each hand, connected to stereo headphones. This effectively placed his ears on his hands. Hand movements, with eyes closed, produced apparent movements of sound sources, and crossing the hands over appeared to reverse the sound field. No perceptual adaptation to this auditory rearrangement was found.

L1 Use

Research on the acquisition of L2 phonology in sequential language learners has stressed the importance of language use and input as a means to accurate production and perception; however, the two constructs are difficult to evaluate and control. This study focuses on the role of language use during the initial stages of development of phonetic categories related to stop voicing and analyzes the relationship between production and perception. Native English-speaking late learners of Spanish provided production/perception data on a weekly basis throughout the course of a seven-week immersion program in which L1 use was prohibited. The production/perception data were analyzed using generalized linear mixed effects models. Generalized additive mixed models were used to analyze and compare the learning trajectories of each modality. The analyses revealed phonetic learning in both production and perception over the course of the program. Perception gains paralleled those of native bilinguals by the conclusion of the program and preceded production gains. This study is novel in that it provides production/perception data in a semi-longitudinal design. Moreover, the beginning adult learners are examined in a learning context in which L1 use was minimal and L2 input was maximized. Taken together, the experiments suggest that L2 phonetic category formation can occur abruptly, at an early stage of development, is perceptually driven, and appears to be particularly fragile during the initial stages of learning.
