| summary |
This paper examines psychological evidence on the nature and role of representations in cognition. Both
internal (mental) and external (physical or digital) representations are considered. It is discovered that both
types of representation are deeply linked to thought processes. They are linked to learning, the ability to use
existing knowledge, and problem solving strategies. The links between representations, thought processes,
and behavior are so deep that even eye movements are partly governed by representations. Choice of
representations can affect limited cognitive resources like attention and short-term memory by forcing a
person to try to utilize poorly organized information or perform "translations" from one representation to
another. The implications of this evidence are discussed. Based on these findings, a set of guidelines is
presented, for digital representations which minimize drain of cognitive resources. These guidelines
describe what sorts of characteristics and behaviors a representation should exhibit, and what sorts of
information it should contain in order to accommodate and facilitate design. Current attempts to implement
such representations are discussed. |
