Word Learning in Deaf Children Using Eye-tracking and Behavioral Measures
NCT05993832 · View on ClinicalTrials.gov ↗
Study Summary
Mutual exclusivity is a word learning constraint in which the learner assumes that a given word refers to only one category of objects. In spoken languages, mutual exclusivity has been demonstrated in monolingual children as young as 17 months and cross-linguistically, while multilingual learners show an attenuated mutual exclusivity bias. Mutual exclusivity has not been robustly demonstrated in deaf children acquiring American Sign Language (ASL). Further, it is unclear if mutual exclusivity applies to those learning both a signed and a spoken language. Like unimodal bilinguals, bimodal bilingual (BiBi) children learn two words for an object, but these words are separated by modality. A BiBi child could therefore assume that all objects have two words (like unimodal bilinguals) or that all objects have one spoken word and one sign (within-modality mutual exclusivity). The goals of the current study are to demonstrate mutual exclusivity in monolingual deaf children acquiring ASL, and to determine if BiBi deaf children utilize mutual exclusivity within each modality.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05993832
The ClinicalTrials.gov registry entry for NCT05993832 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 40 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Boston University Charles River Campus, which has 148 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Deafness appearing as the primary indexed condition, and to 1 intervention — of which input cue is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05993832 reports 1 study location spanning 1 distinct geographic area — top geographies include Massachusetts. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
