A second chance for a first impression: Sensitivity to cumulative input statistics for lexically guided perceptual learning
نویسندگان
چکیده
Listeners use lexical knowledge to modify the mapping from acoustics speech sounds, but timecourse of experience that informs lexically guided perceptual learning is unknown. Some data suggest contingent on initial exposure atypical productions, while other reflects only most recent exposure. Here we seek reconcile these findings by assessing type and promote robust lexcially learning. In three experiments, listeners (n = 560) heard 20 critical productions interspersed among 200 trials during an phase then categorized items ashi–asi continuum in a test phase. Experiment 1, consisted ambiguous fricatives embedded either /s/- or /ʃ/-biasing contexts. Learning was observed; /s/-bias group showed more asi responses compared /ʃ/-bias group. 2, clear consistent context. Order bias were manipulated between-subjects, occurred regardless order which heard. 3, both differed between two groups, no difference groups observed at test. Moreover, results monotonic decrease across line with decreasing stable biasing contexts, replicated novel stimulus sets. contrast previous showing are for learning, current cumulative talker’s input over time.

Lexically Guided Perceptual Learning in Mandarin Chinese
Lexically guided perceptual learning refers to the use of lexical knowledge to retune speech categories and thereby adapt to a novel talker’s pronunciation. This adaptation has been extensively documented, but primarily for segmental-based learning in English and Dutch. In languages with lexical tone, such as Mandarin Chinese, tonal categories can also be retuned in this way, but segmental cate...

This research explored the transition of romantic relationships from meeting online to the first face-to-face date. It is inevitable that impressions of a partner will change to some degree, but how much, and with what consequences? One hundred and fifty users of a popular online dating site participated in the study. They recalled a person whom they had met through the site, reporting their im...
متن کاملComparing lexically guided perceptual learning in younger and older listeners.
Numerous studies have shown that younger adults engage in lexically guided perceptual learning in speech perception. Here, we investigated whether older listeners are also able to retune their phonetic category boundaries. More specifically, in this research we tried to answer two questions. First, do older adults show perceptual-learning effects of similar size to those of younger adults? Seco...
