PPT-Triad tests Collecting and making similarity data

Background The triad test from personal construct psychology and the repertory grid developed by George Kelly in 1955 Adopted by cognitive psychologists and anthropologists to measure similarities among pairs of objects.

Before conducting an investigation, it is important to learn how to organize the data you have collected. . After you have organized the data, you need to make sense of what you have observed..

Painful – A lot of time and energy are spent, but a choice is not made.. Impulsive – A choice is made without adequately finding alternatives or collecting information about the self and alternatives.. Understanding field methods is critical for analysis even if you did not collect the data so you have an idea of what is possible (and what is not).. This is required even with modern remotely sensed data so we can “Ground Truth” the data.
