-\todo[inline]{Modified Frensch/Elio Task. 7 mathematical procedures, learning differently based on presentation order}
+To investigate model behavior and potentially compare it to results from human experiments, it was decided to use an adapted version of the setup described in \citet{Frensch_1991}, which was first used in \citet{Elio_1986}.
+Subjects are put in charge of determining the quality of water samples by performing simple mathematical operations with given indicator values per water sample.
+A water sample has an algae, a solids and multiple toxin and sandstone values, which are randomly generated for each sample.
+There are six different 2-step equations that use these values and a seventh equation using all previously calculated results to determine the final result (see Table~\ref{tab:proc}).
+To solve a procedure, subjects have to locate the values of used variables on the screen.
+Some variables show multiple values, procedures using them indicate how it should be selected after an underscore.
+For example x\_2 means taking the second value of variable x.
+Other procedures require finding the maximum or minimum value of a variable or of previous solutions.
+An example of how the screen could look during a trial is shown in Figure~\ref{fig:frensch}.
+
+The experiment starts with 75 training trials, each representing a water sample, in which a random choice of 6 procedures has to be solved in the order they are presented.
+The last procedure is always picked in the selection process, as it uses all previous results for a water sample to calculate the final solution.
+Afterwards 50 testing trials take place, in which the third procedure from the training phase is switched for the unpicked one.
+There are three conditions that determine the order in which procedures are presented in the training phase, however the procedure for the final result is always last.
+In the fixed condition, the order is randomized once at the start and stays constant during all trials.
+In the random condition, procedure order is randomized between each trial.
+In the blocked condition, the first procedure has to be solved for all trials before moving on to the second procedure, etc.
+The testing phase always uses fixed order.

 How modeled:
 Improvements in task performance are mainly dependent on production compilation, as the order and how efficiently the mathematical operations are performed are the main subject of the task.

 \section*{Results}
 
 Without enabling the subsymbolic system and its learning algorithms, the average time the model takes to solve a specific procedure stays the same over the experiment (Figure~\ref{fig:RT}).
