Scanning and Surveying
Information
This cognitive tool concernes the manner in which
a child scans and surveys information. Young children typically
scann information slowly and direct attion only to narrow segments
of the field of information available. With age, the child scans
more actively and sweeps attention across larger segments of the
field of information.

Focusing Attention
While Ignoring Distractions
This cognitive tool defines the manner in which
a child focuses attention on information that is relevant
while at the same time ignores distrations that are irrelevant.
Young children focus attention on relevant and irrelevant information
almost equally. With age, the child gradually focuses attention
on what is relevant while simultaneously-withholding attention
from information that is distracting and irrelevant.

Remembering Information
This cognitive tool concernes the manner in which
a child remembers information over time - how a child constructs
memory images and compares them with present perceptions. The
young child typically constructs fuzzy images of past information
and fuses these with present perceptions so that suble similarities
are missed. With age, the child constructs sharper images so that
suble similarities and differences between past and present images
are noticed.
