| Hi, I am new to E-prime so any help would be appreciated. I'm setting up a study in which participants have to choose one of three images as being most similar to an image previously shown. There is no correct answer. I want to record which of the three images they choose. I think the best way to do this is to record the position of the cursor at the time of response (the participant will click on the image they choose). I think this is what I need to do but I don't know how to do it. I have used slide objects to put the three images together simultaneously but can't get the cursor to be visible on the slide. Qu 1: how do i make a cursor visible on a slide? Qu2: How do i record the position of the cursor at the time of response? Thanks for any help given

| One solution may be to set three possible response keys and have the participant press the key that corresponds to their selected picture. For example, you may use the 'V', 'B', and 'N' keys for the left, center, and right picture locations. However, if the pictures range in order of appearance, you may need to add a TrialType column in the trial list to indicate sequence type (e.g., sequence 1, sequence 2, sequence 3). Then you will be able to reference this TrialType variable in the data spreadsheet and match the responses with the accurate picture. I am still learning as well, so there may be other solutions to this problem that I am not aware of. Best of luck with your research

Qu 1: how do i make a cursor visible on a slide?
I believe you'd need an inline script with the text below.
'Make mouse cursor visible at run-time
Mouse.ShowCursor True

Ps0u30d4 (4/7/2008) Qu2: How do i record the position of the cursor at the time of response?
I think you need to use HitTest, as illustrated in the "Response Areas for Mouse Input" sample available through the PST web site at http://www.pstnet.com/e%2Dprime/support/samples.asp?Mode=View&SampleID=5. You will have to sign in to download this. Bear in mind that I have never done this myself, I am just going by what I have read from others.
