Electrophysiological markers of pre-lexical speech processing: Evidence for bottom–up and top–down effects on spoken word processing

The present study was designed to investigate the electrophysiological consequences of a mismatch between initial phoneme expectations and the actual spoken input. Participants were presented with a word/nonword prompt with the instruction to delete the initial sound (e.g., snap without the /s/; snoth without the /s/) and determine the resulting segment. Following the prompt, an aurally presented response that matched/mismatched expectations …
