PS102 Lecture Notes - Lecture 7: Dog Bite, Semantic Network, Connectionism
Document Summary
Confidence in a memory has no bearing on accuracy. People can have memories of events they did not experience (info from others, imaginings, stories). All of us have different networks for connecting experience. Think of the most common prototype for a bird seagull (typically don"t think of penguins, ostriches, etc. because they are different). If we were asked what was the most unusual bird, you"d have to think. We think prototypical first and then odd. (takes longer to search through unusual memories). Neural analogy, node (like a neuron) based on action of multiple nodes simultaneously. Hippocampal region is the centre of the action. Formation of new connections (synapses) solidifies memories, making faster memory (that"s why practicing something over and over again solidifies a memory). Have a finite vocabulary that can be combined in infinite ways. Although creative there are some restrictions. These are regularities of language (not necessarily grammar rules).
