PEAT Validation Studies: Cortisol, DPT/N2pc, and ADHD Screening Data

Psychological and physiological validation data for the PEAT assessment includes cortisol levels, DPT/N2pc event-related potentials, and ADHD screening results. Produced by Erick Bourassa-Price and hosted on Harvard Dataverse, the collection supports research into test anxiety and social sciences. The records were last updated in February 2026.

Use Cases

• Correlating cortisol concentrations with ADHD screening outcomes
• Analyzing DPT/N2pc neural markers within the PEAT validation framework
• Benchmarking test anxiety scores against the provided normal distribution data

Strengths

• Integrates physiological cortisol markers with neural DPT/N2pc data
• Includes ADHD screening validation metrics
• Provides normal distribution data for psychological assessment benchmarking

Limitations

• Unknown sample size and record count
• Missing column-level metadata and data dictionary
• Undefined geographic and demographic scope
