Psych Lecture #7
- Confidence in a memory has no bearing on accuracy
- People can have memories of events they did not experience (info from others,
- Links and nodes
- I own a leather chair
- All of us have different networks for connecting experience.
- We are taught in a sequence.
- Eg. “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
- Neural analogy, node (like a neuron) based on action of multiple nodes simultaneously.
The Brain and Memory
- Hippocampal region is the centre of the action.
- Hippocampus – the critical region.
- Neurogenesis – forming new neurons.
- Formation of new connections (synapses) – solidifies memories, making faster memory
(that’s why practicing something over and over again solidifies a memory).

Chapter 8: Language and Thought
Properties of Language
Semantic = meaningful
Effortlessly create new sentences
- Have a finite vocabulary that can be combined in infinite ways.
- Wanna go out for dinner?
- Want to fetch some grub?
- Would you like to dine out?
- Although creative – there are some restrictions.
- These are regularities of language (not necessarily grammar rules).
- Eg. Can end a sentence with a preposition and be understood can’t say “dinner the”.
