Organizational Strategies in Children

Make a photocopy of the pictures on this page and use scissors to cut them apart. In this study you will test a child between the ages of 4 and 8; ideally, it would be interesting to test children of several different ages. Arrange these pictures in random order in a circle facing the child. Instruct him or her to study the pictures so that they can be remembered later. Mention that the pictures can be rearranged in any order they want. After a 4-minute study period, remove the pictures and ask the child to list as many items as possible. Notice two things in this demonstration: (1) Does the child spontaneously rearrange the items at all during the study period? (2) Does the child show clustering during recall, with similar items appearing together?

erive the differential equations in terms of the liquid heights h1 and h2.

  Figure 7.18 shows a liquid-level system in which two tanks have cross-sectional areas A1 and A2, respectively. The volume flow rate into tank 1 is qi. A pump is connected to the bottom….

Derive the differential equation relating the liquid height h and the volume flow rate qi at the inlet.

  Consider the single-tank liquid-level system shown in Figure 7.19, where the volume flow rate into the tank through a pipe is qi. The liquid leaves the tank through an orifice….
