Note: Parameter values in brackets are not free to vary. w_j = attention-weight for dimension j; M_j = lag-j memory strength; θ_j = lag-j sensitivity; P_M, P_θ = primacy multipliers on memory-strength and sensitivity; u, v = background-element strength constants; OLD, NEW = response threshold magnitudes; μ = mean residual RT; κ = random-walk time-scaling constant.
