Explanation:

False Memory: Developed by Sigmund Freud and Pierre Janet.

This is defined as a psychological phenomenon in which an individual recalls or recollects memories about something that didn't happen or else an individual tends to recall an event differently from the way it happened.

Factors:

1. Misinformation.

2. Misattribution.

3. Pre-existing memory or knowledge.

4. Schema.

5. The hindsight bias.

Memory isn't the exact record of a specific event but can be manipulated and reconstructed in various ways, as happened in the case of Ronald.
