Auditory Evoked Potentials Time-Locked to the Second Nonword within Spoken Nonword Pairs

Auditory evoked potentials (AEPs) were acquired from 24 monolingual English and 24 bilingual Polish-English speaking adults. The data includes EEG recordings from two listening conditions (passive and attend) for 560 spoken nonword pairs, time-locked to the second nonword. The dataset was created by Monica Wagner and is available on the Dataverse platform.

Use Cases

• Analyzing neural responses to non-native speech sounds based on the /pt/ versus /pət/ and /st/ versus /sət/ contrasts described.
• Comparing EEG activity between passive listening and active syllable identification tasks as detailed in the experimental conditions.
• Investigating differences in auditory evoked potentials between monolingual and bilingual participant groups.
• Studying the effects of task order (Passive 1-Attend 2 vs. Attend 1-Passive 2) on neural processing of nonwords.

Strengths

• Data from 48 participants, providing a sample size of 24 monolingual and 24 bilingual adults.
• Includes 560 stimulus pairs with specific phonetic contrasts (/pt/ vs /pət/, /st/ vs /sət/).
• Recorded using a 64-channel EEG sensor net with a sampling rate of 500 Hz.
• Test sessions were counterbalanced and separated by a minimum of 2 months (mean five months).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect bias inherent to the specific participant groups and speaker used.
