Examining methodological influences on the rhythmic priming effect: A commentary on Kim, McLaren, and Lee (2024).

The rhythmic priming effect (RPE) refers to improved language performance (typically grammaticality judgements) following regular rhythmic primes compared to various control conditions. This effect has been observed primarily in French, but also in English and Hungarian. However, a recent implementation by Kim, McLaren & Lee (2024), aiming to replicate the RPE in English (Chern, Tillmann, Vaughan & Gordon, 2018), was not successful, inviting a discussion about the conditions under which the RPE could be observed.

Regular rhythmic primes improve sentence repetition in children with developmental language disorder.

Recently reported links between rhythm and grammar processing have opened new perspectives for using rhythm in clinical interventions for children with developmental language disorder (DLD). Previous research using the rhythmic priming paradigm has shown improved performance on language tasks after regular rhythmic primes compared to control conditions. However, this research has been limited to effects of rhythmic priming on grammaticality judgments.

The Importance of Material Used in Speech Therapy: Two Case Studies in Minimally Conscious State Patients.

Speech therapy can be part of the care pathway for patients recovering from comas and presenting a disorder of consciousness (DOC). Although there are no official recommendations for speech therapy follow-up, neuroscientific studies suggest that relevant stimuli may have beneficial effects on the behavioral assessment of patients with a DOC. In two case studies, we longitudinally measured (from 4 to 6 weeks) the behavior (observed in a speech therapy session or using items from the Coma Recovery Scale-Revised) of two patients in a minimally conscious state (MCS) when presenting music and/or autobiographical materials.

You got rhythm, or more: The multidimensionality of rhythmic abilities.

Humans have a remarkable capacity for perceiving and producing rhythm. Rhythmic competence is often viewed as a single concept, with participants who perform more or less accurately on a single rhythm task. However, research is revealing numerous sub-processes and competencies involved in rhythm perception and production, which can be selectively impaired or enhanced.

When Visual Cues Do Not Help the Beat: Evidence for a Detrimental Effect of Moving Point-Light Figures on Rhythmic Priming.

Rhythm perception involves strong auditory-motor connections that can be enhanced with movement. However, it is unclear whether just seeing someone moving to a rhythm can enhance auditory-motor coupling, resulting in stronger entrainment. Rhythmic priming studies show that presenting regular rhythms before naturally spoken sentences can enhance grammaticality judgments compared to irregular rhythms or other baseline conditions.

Processing rhythm in speech and music: Shared mechanisms and implications for developmental speech and language disorders.

Objective: Music and speech are complex signals containing regularities in how they unfold in time. Similarities between music and speech/language in terms of their auditory features, rhythmic structure, and hierarchical structure have led to a large body of literature suggesting connections between the two domains. However, the precise underlying mechanisms behind this connection remain to be elucidated.

What you hear first, is what you get: Initial metrical cue presentation modulates syllable detection in sentence processing.

Auditory rhythms create powerful expectations for the listener. Rhythmic cues with the same temporal structure as subsequent sentences enhance processing compared with irregular or mismatched cues. In the present study, we focus on syllable detection following matched rhythmic cues.

Rhythmic priming of grammaticality judgments in children: Duration matters.

Research has shown that regular rhythmic primes improve grammaticality judgments of subsequently presented sentences compared with irregular rhythmic primes. In the theoretical framework of dynamic attending, regular rhythmic primes are suggested to act as driving rhythms to entrain neural oscillations. These entrained oscillations then sustain once the prime has finished, engendering a state of global enhanced activation that facilitates the processing of subsequent sentences.

Is atypical rhythm a risk factor for developmental speech and language disorders?

Although a growing literature points to substantial variation in speech/language abilities related to individual differences in musical abilities, mainstream models of communication sciences and disorders have not yet incorporated these individual differences into childhood speech/language development. This article reviews three sources of evidence in a comprehensive body of research aligning with three main themes: (a) associations between musical rhythm and speech/language processing, (b) musical rhythm in children with developmental speech/language disorders and common comorbid attentional and motor disorders, and (c) individual differences in mechanisms underlying rhythm processing in infants and their relationship with later speech/language development. In light of converging evidence on associations between musical rhythm and speech/language processing, we propose the Atypical Rhythm Risk Hypothesis, which posits that individuals with atypical rhythm are at higher risk for developmental speech/language disorders.

A stimulus-brain coupling analysis of regular and irregular rhythms in adults with dyslexia and controls.

When listening to temporally regular rhythms, most people are able to extract the beat. Evidence suggests that the neural mechanism underlying this ability is the phase alignment of endogenous oscillations to the external stimulus, allowing for the prediction of upcoming events (i.e.

Regular rhythmic primes boost P600 in grammatical error processing in dyslexic adults and matched controls.

Regular musical rhythms orient attention over time and facilitate processing. Previous research has shown that regular rhythmic stimulation benefits subsequent syntax processing in children with dyslexia and specific language impairment. The present EEG study examined the influence of a rhythmic musical prime on the P600 late evoked-potential, associated with grammatical error detection for dyslexic adults and matched controls.

Song and infant-directed speech facilitate word learning.

Two separate lines of research have examined the influence of song and infant-directed speech (IDS-a speech register that includes some melodic features) on language learning, suggesting that the use of musical attributes in speech input can enhance language learning. However, the benefits of these two types of stimuli have never been directly compared. In this investigation, we compared the effects of song and IDS for immediate word learning and long-term memory of the learned words.

Syntactic and non-syntactic sources of interference by music on language processing.

Music and language are complex hierarchical systems in which individual elements are systematically combined to form larger, syntactic structures. Suggestions that music and language share syntactic processing resources have relied on evidence that syntactic violations in music interfere with syntactic processing in language. However, syntactic violations may affect auditory processing in non-syntactic ways, accounting for reported interference effects.

Syntactic processing in music and language: Effects of interrupting auditory streams with alternating timbres.

Music and language both rely on the processing of spectral (pitch, timbre) and temporal (rhythm) information to create structure and meaning from incoming auditory streams. Behavioral results have shown that interrupting a melodic stream with unexpected changes in timbre leads to reduced syntactic processing. Such findings suggest that syntactic processing is conditional on successful streaming of incoming sequential information.
