A researcher wants to find out whether the way information is presented (written or oral) influences people’s performance on a memory task. In order to do this, the experimenter designs an experiment where 40 participants are randomly assigned to one of two groups. In one group, 20 participants (written) are shown 50 concrete noun words and 50 abstract noun words in the form of a written list. Then, the list is taken and they are asked to list as many of the items that they can remember. In another group, 20 participants (oral) are read 50 concrete noun words and 50 abstract noun words one at a time. Then, they are asked to list as many of the items that they can remember.

Suppose that Robi faces the following opportunity costs: • The opportunity cost of producing 1 unit of bananas is 10 units of apples. • The opportunity cost of producing 1 unit of apples is 0.1 units of bananas. Suppose that Adain faces the following opportunity costs: • The opportunity cost of producing 1 unit of bananas is 0.05 units of apples. • The opportunity cost of producing 1 unit of apples is 20 units of bananas. Suppose that the terms of trade are such that 1 unit of bananas trades for 0.79 units of apples. Because Adain has the lower opportunity cost of producing bananas, they will specialize in the production of bananas and trade with Robi to get apples. Because Robi has the lower opportunity cost of producing apples, they will specialize in the production of apples and trade with Adain to get bananas. Both parties will benefit from this trade. We can see this by noting the following: 1. Consider Adain with and without specialization and trade. Recall that they will specialize in the production of bananas with specialization and trade. • Without specialization and trade, Adain must give up 20 unit(s) of bananas in order to gain 1 unit of apples. ? • With specialization and trade, Adain can produce 1 unit of bananas and trade it for 0.79 units of apples, so they must give up only 20 unit(s) of bananas in order to gain 1 unit of apples. X Hint: What does 1 unit of apples trade for?
