function MDM_PTB_med1_v2(observer);
% This function runs the first two sessions of the task, one Monetary and
% one Medical Block, each block contains 21 trials.
% Task design:
% - trials in monetary and medical blocks should be identical, the only difference is outcome level in money/description
% - outcome has 4 level (vals)
% - 3 probability: 0.25 0.5 0.75
% - 3 ambiguityL 0.24 0.5 0.74
% - 4 repeats for each trial, except that the reference level only has one repeat
% - 78 trials for each domain (monetary/medical), altogether 156 trials
% - add two trials with the reference level in each block, to make
% 160 total trials, easy to split between blocks.
% - add a trial with the reference level at the start of each
% block, will be excluded from imaging anlaysis
% - 6s display + 3.5s RT (average) + 0.5s feedback + 5s ITI = 15s
% - 8 blocks, 21 trials per block, 315+20s per block, about 6 min
% Display problems on the desktop
% - the texts of lottery value and prababilities are up shifted -
% This is probabily because the DrawFormatterText function has wrong
% estimation of vertical postiion. Thus the display may be different
% on different computer. Have swithed to Screen('DrawText')
% - the space between the two squares of feedback cue is too
% large-should not be a issue when connected to a projector
% Skip sync test. May be commented out on the laptop
