I have used my own work from the 80s '90s to provide what I hope is the simplest, most intuitive introduction to factor analysis imaginable. If you find this helpful or have suggestions, please let me know, as I'm hoping to post an improved version of this soon.
This is a recording of a live online lecture that I gave to clinical psychology graduate students at The Fielding Graduate University. It was presented in a graduate course I teach on Research Methods and Design, as part of a lecture on Correlational Analyses
It also introduces an approach to using individual differences to "crack sensory codes" that I pioneered in the '90s. This is actually Part 3 of the Cracking Sensory Codes Lecture. Part 1-2 Includes historical information. The slides are a portion of what I presented at a symposium on individual differences (Chaired by Jeremy Wilmer) at the Vision Sciences Society in 2007.
I made a few errors in this live online lecture:
1) Hugh Wilson's computational "neural" model is based on psychophysical data from increment masking thresholds (WHSwanson, HR Wilson others), not exclusively physiological and anatomical data)
2) Jay Enoch (work on waveguides) is an optometrist and neuroscientist with a PhD in physiological optics. I described him as an ophthalmologist and a physicist. For infants, see the neuroanatomical modeling work of Angela Brown, Velma Dobson, and J. Maier (1987) and Banks & Bennett (1988)
3) I referred to "photoreceptor" when I meant to say "photopigment."
4) John S. (Jack) Werner - my dissertation advisor and mentor, now at UC Davis (Neuroscience). Thanks to Jack for mentoring my first work in this area on this.
5) Brooke Ellison Schefrin, 1954-2010 dailycamera.com/ci_14891015
6) Davida Y. Teller, 1938-2011 legacy.com/obituaries/seattletimes/obituary.aspx?n=davida-y-teller-vida&pid=154237105#fbLoggedOut
7) There was a question about "macular density." She was probably confusing the cone migration I described with macular *pigment* density.
