 \section{Introduction}
 \todo{statement of the problem}
 
+\subsection{Naive Discrimination Learning}
+Since the first experiments in modern learning theory by Ivan Pavlov it's observable, that learning is not only making associations between co-occurring cues and outcomes but discriminating which cues predict the presence and the absence of a outcome \parencite{baayen2015abstraction}.
+
+A naive discrimination learning (\emph{ndl}) model as a 2-layer network implementation of the established learning rules described by \cite{rescorla1972theory} fulfills this and was applied successfully in the language context (e.g. \cite{baayen2016comprehension}).
+
 \section{Simulations}
 \subsection{Experimental Code}
 The simulation code is split in three parts, the creation of the trials, the learning of the monkey and the analysis of the learning results, implemented in the \emph{R Programming Language} \parencite{Rcore}.
