The temperament theory accepted in mainstream psychology, rather than identifying four or however many "types" (whether the Galen humors, Keirsey (Plato) groups or any of the other names various theorists have come up with), instead just measures nine (or more) different factors.
When I had asked Lenore's Thomson about temperament and type, she had mentioned: "reactivity, adaptability, mood, distractibility, persistence, attention span, sensory sensitivity, and the like".
I later stumble on these same factors, finding out they were identified in recent decades, by a trio of theorists who had identified them mainly in children.
Most recently, in one of my wife's counseling books, From Stress to Well Being: Contemporary Christian Counseling (Craig W.Ellison, p. 27, 43)
Nine levels of temperamental differences (Chess, Thomas, Birch)
approach-withdrawal (new stimuli)*
adaptability [less=high stress]*
intensity of reaction [high=stress]*
threshhold of responsiveness
quality of mood [negative=stress]
distractibility [low=high stress]
*Constellations found in children:
respond to new stimili
positively--mildly negative--negative withdrawal
in response to change
moderately intense, mostly positive--
intense, generally negative
You can even see these mentioned here, now:
(Originally, the article only mentioned the four temperaments).
This site claims there are ten (emotional sensitivity added), with a newly discovered eleventh; "Pace":
I would also find other references to "temperament" in children. A book called Galen's Prophecy (Kagan) looked like it would be a promising new look at the old four temperaments, but would also turn out to deal mostly with children.
Another seemingly respectable mainline instrument is the Taylor-Johnson Temperament Analysis (T-JTA), which uses nine similar factors. http://www.tjta.com/abouttjta.htm
Outside of that, "Type A theory" seems to be the only typological system accepted in the mainstream field.
(It has been extended to four or more types in different organizations' version of the theory. Someone created a thread either here or at PerC recently on whether it fits MBTI in amy way. Seems to me, Type A seems to match EJ's).
So I would think, a way for typology to gain some more credibility in the larger field, would be to try to hook up with these factors. (FFM seems to have a little bit more respectability, but you still don't hear about it as much in the field).
It looks to me like many of those factors are somehow related to "expressiveness" and "responsiveness", which I have identified as the primary factors of temperament types. Expressiveness in MBTI/Keirsey would be E/I and cooperative pragmatic, and responsiveness (or "people/task") is directing/informing and structure/motive (which connect SJ with NT and SP with NF).
So what does anyone else think about combining type with these concepts? Is anyone else even familiar with them? Taken a test on them?
