3、 kind of storage system for information. There are three types of these storage systems with different functions that hold information for different amounts of time.

We forget sensory memories almost instantly, unless they passed into another storage system. Examples of the stimuli are what we see and hear in the world, such as【 T3】 _ or the sound of a d
5、oor closing. Short-term memory also called【 T4】 _, holds information for about【 T5】 _ seconds. This is not a very long time. But the information that passes into this system has more meaning for us than just sensory stimulation. Some experts believe that sensory information changes into【 T6】 _ as it
6、 is stored. And others believe that information changes into 【 T7】 _. There is not much room for information in short-term memory. And it did not stay there for very long. Examples of these types of information are telephone numbers, addresses and 【 T8】 _. Long-term memory holds information almost i

8、researchers choose various time intervals for their observation. Intervals may be selected systematically or【 T1】 _. Suppose we want to observe students classroom behaviour. Then in systematic time sampling, our observations might be made during five 20- minute periods,【 T2】 _. The first observation
9、 period could begin at 9 am, the second at 10 am and so forth. However, in random sampling, these five 20-minute periods may be distributed randomly over the course of the day. That is to say, intervals between observation periods could 【 T3】_ some longer others shorter. One point Id like to make is
10、 systematic and random time sampling are【 T4】 _. They are often combined in studies. For example, while observation intervals are scheduled systematically, observations within an interval are made 【 T5】 _. That means the researcher might decide to observe only during 【 T6】 _that are randomly distrib

In about 1930, Calder turned from realistic wire figures to【 T5】 _. He began constructing objects that had circles, squares and other【 T6】 _. To get the shapes to m
14、ove, he used small motors. Then he went one step beyond these early mobiles. He got the shapes in his constructions to move by themselves. A mobile may look simple as it shifts in the wind, but it requires careful construction to work properly. Calder used his【 T7】 _ to create his first mobiles. Oft
