内容

1，看到你的同学在捡垃圾，你在扔垃圾的时候就会think twice。
2．have fun。attracts more students 做志愿者，还可以socialize，enjoy the music。 Question 4Short-term memory: a temporary storage of information．两个特征：decay (not being used) 和interference (new information).
For example，you are out with your classmate and you want to dial someone's cell phone's number which you don't know．So you ask you classmate and call your friend．But after two hours when your friend are not with you，since the number has been used after that，you couldn't remember and recall the number again because it has fade away．That's decay.
The professor uses his own experience to illustrate interference．He went to the bookstore and made a list of the books he wanted，but he forgot to take it with him and left it in his car，but he thought he could remind himself of the books listed．However，when he ran into his friend in the bookstore and talked for a while，all he could remember is the booked his friend mentioned that were quite interesting．The new information interfered with the original one．That's interference. Question 5In the conversation，the man has a problem．He lent his mathematic book to his friend Ted，but the book got ruined，all soaked out when left outside．
There are two possible solutions．The first one is to ask Ted to buy a new copy for him．The second one is to use the copy in the library as the professor put the material on reserved for themQuestion 6一个教授讲动物间的social interaction，说他们whether they know他们之间有interaction？
举了两个例子：1、阐述的是：complex social interaction。例子：大象Elephants：一个大象生病了，其他会照顾他们。
2、阐述的是simple social interaction。例子：fishes 会protect（文中不是这个词）from predators，但是其实他们是不能recognize的，他们甚至不能distinguish each other。
意思是说：鱼们不能感知他们间有interaction，甚至他们都不知道原来大家都是species鱼。
