Research shows that when people are presented an irrelevant distractor stimulus at the end of a word list they must recall, it impairs their ability to recall the last item on the list compared to a control group to whom there was no distractor stimulus. this finding is evidence for which theory of forgetting?

The fact that the appearance of an irrelevant distractor, while an individual is recalling a word list, is evidence of the interference theory of forgetting.

This theory states that forgetting is caused by the appearance of competing memories. There is 2 categories. Retroactive interference occurs when new information interferes with the retrieval of old information and proactive interference occurs when old information interferes with the retrieval of new information.

In this example, this is a case of retroactive interference because an irrelevant distractor (new information) appears while the individual is recalling items on a word list (old information).

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
