Here are 3 clear key points (Secondary Parameters) from the passage:
1. 🧠 Effects vary by individual (“operator-specific”)
The impact of secondary parameters—like:
Volitional (self-chosen intention) vs instructed (assigned intention)
Manual vs automatic trial generation
Type of feedback
➡️ These did not produce consistent results across all participants.
Some operators were unaffected, while others showed strong changes in performance depending on the condition.
2. 🔄 Same person, different conditions → opposite outcomes
A key example showed one operator behaving very differently depending on the setup:
Instructed mode → “psi-miss” (results opposite to intention)
Volitional mode → results aligned with intention (positive correlation)
➡️ This means the experimental condition could completely reverse outcomes, even for the same person.
3. 📊 Hidden effects required deeper statistical analysis
When all data were combined, results looked insignificant (null effect)
But using tools like the chi-squared test revealed meaningful patterns
➡️ Important insight:
Averaging data can hide real structure, and more nuanced analysis is needed to detect anomalies.
If you want, I can explain what “psi-miss” means or why these experiments are debated scientifically.
