Description of the Bivariate Latent Change Score models compared

Model 1 Age predicts latent intercept and slope - Residual variance estimated for latent intercept of g (σ2g0) and Ctx (σ2Ctx0) - Covariance between latent intercepts (σg0-Ctx0) - Self-feedback parameters from level (t-1) to changes (t) β g→Δg β Ctx→ΔCtx

Model 2 - Self-feedback from previous changes (t-1) to subsequent changes (t) ϕ Δg→Δg ϕ ΔCtx→ΔCtx

Model 3 - Couplings from level (t-1) to changes (t) γ g→ΔCtx γ Ctx→Δg

Model 4 - Couplings from previous changes (t-1) to subsequent changes (t) ξ Δg→ΔCtx ξ ΔCtx→Δg

Model 5 - Residual variance estimated for latent slope of g (σ2gs) and Ctx (σ2Ctxs) - Covariance between latent slopes (σgs-Ctxs)

Model 6 - Covariances between latent slopes and intercepts: σg0-gs, σCtx0-Ctxs, σg0-Ctxs, σCtx0-gs

Note: All the parameters estimated in a model are also estimated in subsequent models
