stuck on dual-task experiment

[fs_87]

Hi everyone, 

I'm a novice at e-prime trying to design a dual-task experiment and need 
some help. 

Primary task (Reasoning problems): 40 problems that will appear on the 
screen one at a time for 10 seconds. Participants will read the problem 
presented and respond appropriately. 
Secondary task (Stroop task): During the presentation of a given primary 
problem, a small pop-up window will appear at a fixed location on the 
computer screen at random time intervals (between 2 – 10 seconds) for 600 
milliseconds. The pop-up will contain a word with a name of a colour. The 
colour of the word’s font will either match or not match the name of the 
colour. Participants will be asked to respond to the pop-up as soon as they 
notice it by pressing either the letter ‘M’ (match between the colour name 
and the font colour) or the letter ‘N’ (no-match). The pop-up window will 
disappear after 600 milliseconds or as soon as the letter M or N is 
pressed. Participants will be instructed to remember the colours in which 
the words appear. Once they respond to the primary problem, they will be 
required to enter the colours accurately and in order that they appeared.

All the dual task experiments I've seen online only require participant 
responses for one of the two tasks. In addition, I'm not sure how to begin 
coding both tasks to run together. Is anyone willing to help me out or send 
a similar template for me to learn from? Any help is much appreciated. 
Thank you
