PSI MISS

 A

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.
