Lorianne was heading home for the holidays so that was a good excuse to have a household brunch!
In the afternoon Matthew got to go back and play at the Childhood Cognition and Learning lab. It was pretty interesting to watch and Amelia enjoyed playing with the toys outside. I took a photo of the experiment descriptions for those interested.
I was interested that Matthew was quite able to save his marbles and delay getting stickers / candy in order to have more later. In general he eats all the sweets immediately, but I think that's because he reckons that if he's out there is a chance someone will share with him whereas in the experiment he knew he'd get more for sure if he waited. Hopefully this bodes well for saving money in the bank.
For his future item selection he was supposed to bring an apple back for the dragon, but he picked the "wrong" fruit. Later he was telling me about how the dragon liked apples best so I asked him why he didn't bring the apple for the dragon. "I didn't want to" he said. Well okay then.
But the most exciting experiment for me was the marshmallow task. Matthew was left alone in the room with a bell that he could ding at any time to bring the experimenter back. If he dinged the bell, he only got a few marshmallows, but if he waited, he would get more. I was sure he'd ring the bell right away, because he REALLY enjoyed using the bell during the practice. But then it became obvious that he was determined to wait it out. I would have loved to see if he would go the full 20 minutes but about five minutes in it became clear that he had to poo. Badly. He was dancing around completely determined not to ring the bell so mercifully they ended the experiment early but I was sad that we didn't get to try it again and they didn't get useful data for this component. In the bathroom I told him he should have rung the bell if he had to go. "But I wanted more marshmallows!" he exclaimed.
