How to use MediaLab creat WAT and IAT experiment?

Hi

I have two questions that I need help.

(1) I am goning to show 100 slides for participates and record their voice answer,I want the RT start from stimuli onset end at participate start to talk, what should I do? And all the answers will be 1 voice file or 100 voice files?

(2)I want to design a IAT experiment, i will show some words on the top and middle in the screen and I want to show two choices in the two sparate sides of bottom, and I want participate respones by key in A and L by keybord, how should I do? and according IAT if participate give wrong answer(example I want participate press A but participate press L), there will show wrong answer in the screen, how shuold I make this?

Thank You

Both of these would be most easi8ly done in DirectRT--do you have access to it? It even comes with an IAT sample and a voice recording sample that you could modify. MediaLab isn't really designed to do studies like an IAT although it could do the voice recording study.
