Summary: Sheng-Fu

Using the rhotic sound as the target, this study aimed to examine General American English listeners’ processing of three types of word variants: standard accent with high frequency (the GA accent, rhotic), standard accent with a lower frequency (the British English accent, rhotic), and non-standard accent with a lower frequency (the New York City accent, non-rhotic). Whether an accent is standard or not depends on accompanying phonetic information, thus a rhotic sound may be standard with a BE voice, and non-standard with an NYC voice, and this distinction is verified by a social perception task included in this study. The results of a semantic priming experiment shows that GA primes, but not the non-rhotic NYC primes, facilitate recognition of semantically related items. In addition, the non-rhotic BE primes have similar facilitation effects as the GA primes. The results of a false-memory experiment showed that listeners falsely recalled more lures for NYC sets and were equally good at suppressing BE and GA lures. Since both experiments showed the recognition equivalence of variants with different frequencies (BE and GA), the authors suggested that some linguistic events (e.g., instances of BE sounds) may be encoded more strongly than others (e.g., instances of GA sounds), so that frequency is not the best predictor of how listeners internalize these events.
