Interesting read! I've been trying to think of events from my childhood... Nothing's sticking out yet. What about you, hubski? Any fond memories from about 3.5 years old?
The emphasis on infused emotion is interesting for me. I have a childhood memory of lying on the surgery table just before they anaesthetised me, followed by a memory of waking up after surgery when my mother told me that the nurse was named like my sister. :) I always wondered why I remembered the last part so strongly, especially because I fell back to sleep immediately after. Strong emotion seems like a reasonable explanation.
Emotion is such a powerful thing! Come to think of it, I've got a very vivid memory of absolutely freaking out in a dentist's chair at about three or four years old... The dentist was not very good with children and I didn't like the scary tools he was trying to use on me! I left without getting my teeth checked and we never went back to that dentist!
