Supplementary Data on Math Anxiety and Skills in Brazilian First Graders

A supplementary document from a study investigating the selective impact of math anxiety on mathematical skills in first-grade students. The study involved 229 Brazilian first graders from 10 public schools, assessing symbolic and nonsymbolic math skills, math anxiety, and other cognitive measures. The document was authored by Angélica Polvani Trassi and last updated in April 2026.

Use Cases

• Analyzing correlations between math anxiety and specific symbolic math skills based on the study's regression analysis.
• Investigating the differential impact of anxiety on number production versus number sense based on the described findings.
• Studying the role of cognitive controls like working memory in early math performance based on the discussion points.

Strengths

• Includes data from 229 participants, providing a substantive sample size for analysis.
• Assesses multiple cognitive domains including math anxiety, nonverbal reasoning, and language skills.
• The study design controls for variables like age, gender, and nonverbal reasoning.

Limitations

• The primary data file is a 661.6 KB DOCX document; the underlying structured data is not directly accessible.
• Column-level documentation and sample data are unavailable, requiring manual extraction and interpretation.
• Row count and data structure are unknown, limiting suitability assessment for direct computational analysis.
