types of memory are not relevant to our study of perception in visualization:

• . Sensory memory.

• Short-term memory.

• Long-term memory

• middle term memory

The measures of visualization are:

• 1.Expressivenes

• 2.Effectiveness

• 3.Both a&b

• 4.none

-----------thus measures the concentration of information

________ thus measures a specific cost of information perception

If Effectiveness is more—

• 1.rendering is more interpretation is more

• 2. rendering is less &interpretation is less

• 3. rendering is more interpretation is less

• 4.None

• The points show that as x-values increase, y-values decrease.

• The points show that as x-values decrease, y-values stay the same.

• The points show that as x-values decrease, y-values increase.
