I’m new in superlab and have some probably pretty basic questions.
First, I want to create a rating scale. The scale needs to be shown under a picture which will be presented simultaneously with it. Now I’m not sure which type of file to use for the scale: If I use text, I don’t know how to create a visual scale; if I use a picture file, I don’t know how to determine its position on the screen so that it will be presented underneath the pic to be rated (The participant answers by pressing keys, so there’s no need to worry about on-screen responses.)
Then, in another trial block, I’m using a stimulus list for my events. Is it possible to randomly have one of two different ISI’s between my stimuli?
And my last question refers to the response keys: is it possible for me to block all keys on the keyboard that are not important for the task?
Although my questions might be very basic I’d really be grateful for some advise.
