The effects of transcranial direct current Stimulation on Working memory and reading skill

Malik M. Alrefaei published a dataset on figshare in April 2026 detailing a double-blind randomized controlled trial. The study involved 40 adults with dyslexia, split into experimental and control groups, to assess the effects of transcranial direct current stimulation (tDCS) on working memory and reading skills. Linear regression models were used to analyze pre-test and post-test score differences.

Use Cases

• Analyzing the efficacy of tDCS intervention based on pre-test and post-test score comparisons mentioned in the description
• Modeling within-person differences in cognitive scores based on the described regression methodology
• Comparing experimental and control group outcomes for a clinical trial with 40 participants
• Investigating the relationship between working memory and reading skill improvements in adults with dyslexia

Strengths

• Data originates from a structured double-blind randomized controlled trial, a robust experimental design
• Includes results from 40 adult participants with dyslexia, providing a defined sample size
• Uses linear regression models for analysis, suggesting a quantitative, reproducible approach

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download
• The dataset is very small at 59.9 KB, indicating limited scope and likely summary-level data
• Description metadata is limited; actual data quality and granularity require manual inspection after download
