DESCRIPTION:Most of psychology and cognitive neuroscience is b
 ased on cross-sectional investigations\, that is\,
  participants are generally measured once. A key l
 imitation of cross-sectional data is that associat
 ions between brain and behaviour may reflect a var
 iety of underlying processes that cannot readily b
 e distinguished. We will discuss two emerging tech
 niques\, network analysis and latent change models
 \, that are instead tailored to the study of chang
 e over time.\n \nPsychopathology\, such as depress
 ion or anxiety\, is traditionally characterized as
  an underlying illness that causes symptoms. A nov
 el and rapidly emerging view on psychopathology ca
 lled network analysis focuses on the mutual influe
 nces between symptoms. Rather than “I am sad\, sle
 ep poorly and can’t concentrate because I’m depres
 sed”\, we might say “I slept poorly\, therefore I 
 can’t concentrate\, and that makes me sad\, which 
 causes me to sleep poorly\, etc.”. Here we will ex
 plore how changing network parameters may underlie
  the onset of depression in adolescence\, and how 
 they may change again during successful psychother
 apy treatment.\n \nIn a second talk we will focus 
 on a powerful class of structural equation models 
 known as latent change score (LCS). This general m
 odelling approach links longitudinal data to the a
 nalytical strengths of the SEM framework\, which i
 nclude model testing\, model comparison\, measurem
 ent invariance\, and measurement error. We will il
 lustrate how these models capture how our cognitiv
 e abilities emerge (in adolescence and early adult
 hood) and decline (in old age).\n
