Latent change score briefest history

Latent Change Scores, developed by Jack McArdle in 1993 [1,2] are an amazingly simple and flexible tool for analysis of changes. The original models shown in the original chapters are below:
and

As you can see, this didn't look as simple as the LCS tool really is, so McArdle moved to make it more appealing, as in [3] and [4]:



The LCS definition and setup can be seen in an applied manner [that's how one can define the parameters in fact] as in [5]:
This simple device is the one that allows for modeling complex hypotheses about dynamic patterns of changes, like the one in [6] below:

update 7/25/18: 
Several change causal models are presented in detail in this wonderful book below, where an amazingly similar model is shown on p. 19, (Fig. 2.3 below), as an alternative of a simple autoregressive 1 (AR1) model most users can relate to (Fig. 2.2 below). The book has many other hidden gems, and deserves a close reading!
