“…But a recent study found semantic priming using auditory prime–target word pairs (Daltrozzo et al, 2011), which was in contrast to the study by Kouider and Dupoux (2005). However, the more recent study showing semantic priming used very low-intensity primes that were not possible to categorize, instead of also using time-compression and masking, which could account for the discrepant findings.…”

Auditory perception and cognition entails both low-level and high-level processes, which are likely to interact with each other to create our rich conscious experience of soundscapes. Recent research that we review has revealed numerous influences of high-level factors, such as attention, intention, and prior experience, on conscious auditory perception. And recently, studies have shown that auditory scene analysis tasks can exhibit multistability in a manner very similar to ambiguous visual stimuli, presenting a unique opportunity to study neural correlates of auditory awareness and the extent to which mechanisms of perception are shared across sensory modalities. Research has also led to a growing number of techniques through which auditory perception can be manipulated and even completely suppressed. Such findings have important consequences for our understanding of the mechanisms of perception and also should allow scientists to precisely distinguish the influences of different higher-level influences.

“…Future approaches could control the level of attention using for instance subliminal stimulation (Daltrozzo et al, 2011). Finding ERP effects of SL under subliminal stimulation would rule out the alternative attentional explanation, indicating that these ERP effects are indices of SL per se and not indirect effects of increased attention to newly learned materials.…”

Statistical-sequential learning (SL) is the ability to process patterns of environmental stimuli, such as spoken language, music, or one’s motor actions, that unfold in time. The underlying neurocognitive mechanisms of SL and the associated cognitive representations are still not well understood as reflected by the heterogeneity of the reviewed cognitive models. The purpose of this review is: (1) to provide a general overview of the primary models and theories of SL, (2) to describe the empirical research – with a focus on the event-related potential (ERP) literature – in support of these models while also highlighting the current limitations of this research, and (3) to present a set of new lines of ERP research to overcome these limitations. The review is articulated around three descriptive dimensions in relation to SL: the level of abstractness of the representations learned through SL, the effect of the level of attention and consciousness on SL, and the developmental trajectory of SL across the life-span. We conclude with a new tentative model that takes into account these three dimensions and also point to several promising new lines of SL research.

“…Like the words, the pseudo‐words were monosyllabic, phonotactically legal and pronounceable, but meaningless combinations of sounds in French. Overall, the pseudo‐words contained all the phonemes of the words, as done in previous studies investigating speech perception (Daltrozzo et al ., ; Signoret et al ., ). The average number of phonemes of the pseudo‐words was carefully matched to that of the words (2.3 for the words against 2.4 for the pseudo‐words; t 718 = −1.52, P > 0.125).…”

“…In the auditory modality, recent studies show evidence of lexical processing for stimuli presented below categorization (Kouider & Dupoux, ), and below detection (Signoret et al ., ) thresholds. Semantic processing of auditory stimuli has also been observed below the auditory categorization threshold (Daltrozzo et al ., ).…”

“…These auditory stimuli were presented at two intensity levels of presentation: one at which participants could perform a categorization task at both the lexical (differentiating between word and pseudo‐word) and the phonological (differentiating between pseudo‐word and complex sound) levels; and the other at which they were unsuccessful in the categorization task at the phonological and lexical levels, similarly to Daltrozzo et al . (). EEG methodology was used, and particular attention was dedicated to the spectral response for lexical access described by Pulvermüller et al .…”

Recent human behavioral studies have shown semantic and/or lexical processing for stimuli presented below the auditory perception threshold. Here, we investigated electroencephalographic responses to words, pseudo-words and complex sounds, in conditions where phonological and lexical categorizations were behaviorally successful (categorized stimuli) or unsuccessful (uncategorized stimuli). Data showed a greater decrease in low-beta power at left-hemisphere temporal electrodes for categorized non-lexical sounds (complex sounds and pseudo-words) than for categorized lexical sounds (words), consistent with the signature of a failure in lexical access. Similar differences between lexical and non-lexical sounds were observed for uncategorized stimuli, although these stimuli did not yield evoked potentials or theta activity. The results of the present study suggest that behaviorally uncategorized stimuli were processed at the lexical level, and provide evidence of the neural bases of the results observed in previous behavioral studies investigating auditory perception in the absence of stimulus awareness.
