چکیده
Objectives: This research investigated three potential asymmetries in the production and perception of homophone spelling errors: aging, homophone dominance, and priming. A homophone spelling error occurs when a contextually appropriate word (beet) is replaced with its homophone (e.g., beat glaze). Two experiments investigated young and older adults' written production and detection of these errors. Method: Participants wrote sentences (Experiment 1) or detected errors in sentences (Experiment 2) containing a dominant homophone (beat) or subordinate homophone (beet). Homophones were preceded by a prime (neat) that shared orthography with the contextually inappropriate homophone (beat) or by an unrelated control word (fun). Results: Results revealed an aging asymmetry in production and detection as a function of dominance. Older adults made more errors than young adults when producing dominant homophones but fewer errors in producing subordinate homophones. In contrast, older adults consistently made fewer errors than young adults when detecting homophone errors. Independent of aging, dominance had similar effects on production and detection, with more errors on subordinate homophones. Priming had asymmetric effects different from aging by increasing errors in production but not detection. Discussion: These results suggest aging uniquely dissociates perception and production of homophone spelling and demonstrate circumstances under which aging benefits language

متن کاملAsymmetries between production and perception of consonant length*
This paper addresses context-dependent asymmetries between the perception and production of consonant length in three distinct languages: Russian, American English, and Italian. These asymmetries are argued to present evidence of the perceptual advantage for consonant length identification in certain phonetic environments and play an important role in defining the crosslinguistic distribution o...
متن کاملStructural white matter asymmetries in relation to functional asymmetries during speech perception and production
Functional hemispheric asymmetries of speech production and perception are a key feature of the human language system, but their neurophysiological basis is still poorly understood. Using a combined fMRI and tract-based spatial statistics approach, we investigated the relation of microstructural asymmetries in language-relevant white matter pathways and functional activation asymmetries during ...
متن کاملCompression effects and perceptual asymmetries
This paper reports the results of two English experiments on timing and perception. The finding is that temporal patterns in production correspond to asymmetries in perception. We argue that these phenomena are best described in terms of auditory rather than articulatory representations. The production data concern compression effects, whereby, in syllables with a greater number of segments, ea...
متن کاملAsymmetries between Speech Perception and Production Reveal Phonological Structure
It has been observed that in production, the boundary between the vowels /i/ and /e/ is diagonal, i.e. it involves both F1 and F2; in perception, by contrast, the boundary has been observed to be horizontal, i.e. listeners do not use F2 as a cue for distinguishing the two vowels. The same is true of the /u–o/ boundary. With computer simulations of virtual language learners we show that this per...
