This chapter was on thinking and language. There was multiple things to talk about in this chapter but the 3 main things I am going to talk about are prototypes, algorithms, and what heuristics are.
We have different prototypes for different things. We make mental images to what something is suppose to look like. For example when someone says "square" we automatically think and picture a shape that has 4 congruent sides and angles. Everyone might have a little different prototype then others. Some people might see a little different image in their head about things. Making everyone unique. Another thing is that some people might see a penguin more like a bird then a robin, it depends how much they are around each bird and their views on it.
Algorithms are a step-by-step procedures that guarantees a solution. They can be time consuming and taking a lot of work. It is pretty much like trail and error. Sometimes it could be really fast guess you are a good guesser and tried and excelled the first time, but other times it could take you for ever to figure out. For example a math problem. If you didn't know how many times 5 went into the number 2,225, you would have to try a lot of numbers to get to 2,225 (if you didn't have a calculator).
Heuristics is a quicker way to find a solution. We tend to find ways to combined things or think of ways that seem logical. For example in the math example from above, we would know that the last number would have to be either a 5 or a 0, that means we can eliminate 8 numbers it could end with. Also we know that 5 goes into 100 four times so that means there is probably going to be a 4 as well in the answer. You still have to use trial and error to find the rest of the answer but its a little quicker then algorithms.
(the answer is 445)
