Abstract
This study investigates the impact of phonetic realisation and prosodic prominence on visual letter identification, focusing on the letter in German bisyllabic words. Building upon previous research, a computerised letter search task was conducted with 78 skilled adult readers. Words featuring different phonetic realisations of (/eː, ɛ, e, l̩, n̩, ɐ/) in stressed and unstressed first and second syllables were systematically included. Analyses of error rates and response times revealed a graded pattern in the detection of , with the closed long (/eː/) and closed short (/e/) realisations being easiest to detect, open (/ɛ/) and near-open central (/ɐ/) vowels becoming incrementally harder, and silent vowels in syllabic consonants (/n̩/) being the most challenging. Results divided by position and stress of the syllable containing the target letter further indicated influences of prosodic prominence. The findings contribute to understanding the intricate interplay of grapheme-phoneme correspondences and prosodic structure in skilled readers' visual letter recognition.
期刊介绍：
Promoting the interests of scientific psychology and its researchers, QJEP, the journal of the Experimental Psychology Society, is a leading journal with a long-standing tradition of publishing cutting-edge research. Several articles have become classic papers in the fields of attention, perception, learning, memory, language, and reasoning. The journal publishes original articles on any topic within the field of experimental psychology (including comparative research). These include substantial experimental reports, review papers, rapid communications (reporting novel techniques or ground breaking results), comments (on articles previously published in QJEP or on issues of general interest to experimental psychologists), and book reviews. Experimental results are welcomed from all relevant techniques, including behavioural testing, brain imaging and computational modelling.
QJEP offers a competitive publication time-scale. Accepted Rapid Communications have priority in the publication cycle and usually appear in print within three months. We aim to publish all accepted (but uncorrected) articles online within seven days. Our Latest Articles page offers immediate publication of articles upon reaching their final form.
The journal offers an open access option called Open Select, enabling authors to meet funder requirements to make their article free to read online for all in perpetuity. Authors also benefit from a broad and diverse subscription base that delivers the journal contents to a world-wide readership. Together these features ensure that the journal offers authors the opportunity to raise the visibility of their work to a global audience.
