Misinterpretation Of African American English Bin By Adult Speakers Of Standard American English Nigora Abdiyeva1

4.3.2. PERCEPTION TASK.
This task assessed participants’ abilities to differentiate BIN and been tokens. Participants heard four types of pairs presented over headphones: (1) same been–been token (n ¼ 18), (2) same BIN-BIN token (n ¼ 18), (3) tokens that differed between category (been-BIN; n ¼ 9, BIN-been; n ¼ 9), and (4) tokens that differed within category (different been-been tokens; n ¼ 9, different BIN-BIN tokens; n ¼ 9). After hearing each pair, participants were instructed to indicate, via a button press, whether the two items were the same or different.

These pairs were constructed by splicing individual been and BIN tokens from the sentences recorded by the native AAE-speaker. Once individual tokens were spliced, they were combined into pairs and separated by 1000 ms of silence.
