% reference <MATLAB for neuroscientist 2nd> Project 7
% (Posner,1980)
%
% This script contains: generating experiments, collecting response.
%
% The experiments sessions include:
%   Cues are present 4 times in each grid (144 trial in total);
% 	2 times for valid cue, 2 for unvalid cue,
% 	Cue Intervals include 100 ms and 300 ms, number of each is equal.
%   Trials display in random sequence;
% 	Total trial numbers: 
% 	36 grids ¡Á 4 repetition ¡Á 2(valid or not) ¡Á 2 (internals) = 576. 

% Responses and data includes:
%       vision search type, stimulus number, target or not, response, response time 
% All records will be saved in one excel per subject
