Memory Performance in Mild Traumatic Brain Injury with 72 Participants

A 2026 study by Ratiu and LaCroix compares short-term and working memory performance between 36 individuals with mild traumatic brain injury (mTBI) and 36 matched neurotypical controls. The dataset likely contains results from verbal and nonverbal memory tasks analyzed using ANOVA and hierarchical cluster analysis. It was published in the American Journal of Speech-Language Pathology and shared on figshare.

Use Cases

• Compare verbal versus nonverbal memory task performance based on the described experimental contrasts.
• Analyze the effect of list length on memory performance based on the study's central analysis.
• Identify distinct cognitive performance profiles based on the hierarchical cluster analysis described.
• Investigate the relationship between task complexity and group differences based on the reported results for working memory tasks.

Strengths

• Includes data from 72 total participants (36 mTBI, 36 controls), providing a matched-pairs study design.
• Analyzes both short-term memory (STM) and working memory (WM) across verbal and nonverbal modalities.
• Uses hierarchical cluster analysis to explore individual variability beyond group averages.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (232.4 KB), indicating limited scope.
