Abstract Lexical priming is known to arise from phonological similarity between prime and target, and this phenomenon is an important component of our understanding of the processes of lexical access and competition. However, the precise nature of the role of phonological similarity in lexical priming is understudied. In the present study, two experiments were conducted in which participants performed auditory lexical decision on CVC targets which were preceded by primes that either matched the target in all phonemes (CVC condition), in the first two phonemes (CV_ condition), the last two phonemes (_VC condition), the initial and last phonemes (C_C condition) or no phonemes (unrelated condition). Relative to the unrelated condition, all conditions except CV_ led to facilitation of response time to target words. The _VC and C_C conditions led to equivalent facilitation magnitude, while the CV_ condition showed neither facilitation nor inhibition. Accounting for these results requires appeal to processes of lexical competition and also to the notion that phonemes do not lend equivalent phonological similarity; that is, vowels and consonants are processed differently.

Temporal Overlap

Efficient word recognition depends on the ability to overcome competition from overlapping words. The nature of the overlap depends on the input modality: spoken words have temporal overlap from other words that share phonemes in the same positions, whereas written words have spatial overlap from other words with letters in the same places. It is unclear how these differences in input format affect the ability to recognize a word and the types of competitors that become active while doing so. This study investigates word recognition in both modalities in children between 7 and 15. Children complete a visual-world paradigm eye-tracking task that measures competition from words with several types of overlap, using identical word lists between modalities. Results showed correlated developmental changes in the speed of target recognition in both modalities. Additionally, developmental changes were seen in the efficiency of competitor suppression for some competitor types in the spoken modality. These data reveal some developmental continuity in the process of word recognition independent of modality, but also some instances of independence in how competitors are activated.

Structural Processing

To investigate how proficient pianists comprehend pitch relationships in written music when they first encounter it, we conducted two experiments in which proficient pianists’ eyes were tracked while they read and played single-line melodies. In Experiment 1, participants played at their own speed; in Experiment 2, they played with an external metronome. The melodies were either congruent or anomalous, with the anomaly involving one bar being shifted in pitch to alter the implied harmonic structure (e.g. non-resolution of a dominant). In both experiments, anomaly led to rapid disruption in participants’ eye movements in terms of regressions from the target bar, indicating that pianists process written pitch relationships online. This is particularly striking because in musical sight-reading, eye movement behaviour is constrained by the concurrent performance. Both experiments also showed that anomaly induced pupil dilation. Together, these results indicate that proficient pianists rapidly integrate the music that they read into the prior context and that anomalies in terms of pitch relationships lead to processing difficulty. These findings parallel those of text reading, suggesting that structural processing involves similar constraints across domains.

Abstract Communication through spoken language is a central human capacity, involving a wide range of complex computations that incrementally interpret each word into meaningful sentences. However, surprisingly little is known about the spatiotemporal properties of the complex neurobiological systems that support these dynamic predictive and integrative computations. Here, we focus on prediction, a core incremental processing operation guiding the interpretation of each upcoming word with respect to its preceding context. To investigate the neurobiological basis of how semantic constraints change and evolve as each word in a sentence accumulates over time, in a spoken sentence comprehension study, we analyzed the multivariate patterns of neural activity recorded by source-localized electro/magnetoencephalography (EMEG), using computational models capturing semantic constraints derived from the prior context on each upcoming word. Our results provide insights into predictive operations subserved by different regions within a bi-hemispheric system, which over time generate, refine, and evaluate constraints on each word as it is heard.
