How Can We Discover and MeasureIndividual Differences in
T&P?
AJ Shackman10 February 2015Todays Conceptual RoadmapWhere did
the fundamental dimensions of T&P come from? How were they
discovered? What are their limitations?
How should we measure T&P? What is the value of adopting
biological measures?
What statistical properties do we need to assess if we turn to
biological measures of T&P?

From Measures to Models The Case of the 5 Factor Model, or,
How did we get the factors thatwe were given?
Why 5 Factors? Words, words, words Lexical Hypothesis,"All
aspects of human personality which are or have been of importance,
interest, or utility have already become recorded in the substance
