The perception of speech can be flexible, influenced by multiple sources of information, and plastic, tuned over time to cumulative experience. This chapter provides examples of cognitive neuroscience research, presented at a workshop on speech and lexical processing. Section I demonstrates effects of different sources of semantic information on perception and brain activity. Section II presents evidence for the role of internally generated linguistic predictions in guiding adaptive plasticity, and for the potential involvement of a cerebellar-mediated supervised learning mechanism. Finally, Section III examines the relationship between flexibility and adaptive plasticity and underscores the need for considering their underlying neurobiological mechanisms and their interactions with cognitive processes, and other factors that contribute to generalization in order to further elucidate this relationship.The perception of speech depends on mapping a highly variable and complex acoustic signal onto meaningful sounds and words. However, when the speech signal violates learned regularities due to natural, environmental, or synthetic distortions of the speech signal, accurate perception can be maintained through adjustments in mapping the acoustic signal onto more abstract linguistic information. Such adjustments are facilitated by disambiguating contexts that influence perception of the acoustic signal to be more consistent with the context. They can also accumulate, over brief periods of exposure, and affect perception of later instances of the distorted speech (adaptive plasticity). Current cognitive neuroscience research continues to investigate the underlying mechanisms and neural systems that support these flexible and adaptive properties of speech processing.The main goal of this chapter is to review findings presented at a workshop on speech and lexical processing, largely from our research group and collaborators, on studies investigating flexible and adaptive processes in speech perception. Section I of this chapter describes behavioral and functional neuroimaging results that provide evidence for interactions across multiple levels of language

“…For example, it is unclear whether differences in attention would be observed in any bilingual group, or if specific knowledge of Chinese drives the attentional differences observed in the current study. Recent ERP evidence demonstrates that native Chinese listeners modulate temporally selective attention while listening to Chinese speech according to interacting factors such as accentuation, semantic congruence, and lexical predictability (Li, Lu, & Zhao, 2014; Li & Ren, 2012). It is not clear from these studies whether Chinese listeners select specifically for word onsets versus other time points in their native language, and in fact several aspects of the language are likely to encourage different attentional strategies during Chinese speech perception.…”

Attention is required during speech perception to focus processing resources on critical information. Previous research has shown that bilingualism modifies attentional processing in nonverbal domains. The current study used event-related potentials (ERPs) to determine whether bilingualism also modifies auditory attention during speech perception. We measured attention to word onsets in spoken English for monolinguals and Chinese-English bilinguals. Auditory probes were inserted at four times in a continuous narrative: concurrent with word onset, 100 ms before or after onset, and at random control times. Greater attention was indexed by an increase in the amplitude of the early negativity (N1). Among monolinguals, probes presented after word onsets elicited a larger N1 than control probes, replicating previous studies. For bilinguals, there was no N1 difference for probes at different times around word onsets, indicating less specificity in allocation of attention. These results suggest that bilingualism shapes attentional strategies during English speech comprehension.

“…In the field of psycholinguistics, quite a lot of research has investigated how listeners' selective attention is guided by the acoustic cues of speech signals. It has found that, salient acoustic cues, such as accentuation or word onsets, tend to attract more attention resources during speech processing (Astheimer and Sanders 2009;Cutler 1976;Li and Ren 2012;Li et al 2014;Sanford et al 2006). Accentuation, or pitch accent, is one type of prosodic information in the speech signal, which reflects the relative prominence of a particular syllable, word, or phrase in an utterance realized mainly by modulations of pitch (Shattuck-Hufnagel and Turk 1996).…”

The present electroencephalogram study used an attention probe paradigm to investigate how semantic and acoustic structures constrain temporal attention during speech comprehension. Spoken sentences were used as stimuli, with each one containing a four-character critical phrase, of which the third character was the target character. We manipulated not only the semantic relationship between the target character and the immediately preceding two characters, but also the presence/absence of a pitch accent on the first character. In addition, an attention probe was either presented concurrently with the target character or not. The results showed that the N1 effect evoked by the attention probe was of larger amplitude and started earlier (enhanced attention) when the target character and the preceding two characters belonged to the same semantic event than when they spanned a semantic-event boundary, and this effect occurred only in the un-accented conditions. The results suggest that, during speech comprehension, the semantic level of event-structure can constrain attention allocation along the temporal dimension, and reverse the attention attenuation effect of prediction; meanwhile, the semantic and acoustic levels of event-structure interact with each other immediately to modulate auditory-temporal attention. The results were discussed with regard to the predictive coding account of attention.
