% Scarcity Games
% Wenwen Xie, edited by Inge Huijsmans

% Start editing 2014-11-12
%
% In this experiment participants play three games: the Dot Comparison, Dot
% Counting and Shape Matching game. They play these three games in
% randomized order. They will play these three games in sequence twice,
% once in the 'Abundance' condition, once in the 'Scarcity' condition.
% The order of these conditions are counterbalanced between parcitipant.
% After participants have played a fixed number of trials
% in each game, the task switches to a different task. This different task
% can be implemented by a function.
%
% Feedback on each trail of each of the tasks is fixed for all participants.
