I have a set-up where in the first part of the task, participants have 3 response options (1, 2 or 3). According to which one they select, the task then proceeds to one of three lists. I am using the following script after the first trialproc: If Allbuttons.RESP = "1" Then List1.Run ElseIf Allbuttons.RESP = "2" Then List2.Run Else List3.Run End If The problem is that I am getting an error message when I try to run it: "Factor error: Invalid context in list 1" (or list 2, or list 3, according to which response I make on the first part of the experiment). I'm not really sure what that error message means? When I delete my script, the whole thing works fine (it's just that then I get the three possible lists run sequentially). Perhaps I have not set-up the different levels of the task correctly - should the first part, and then the script, and then the three lists, all come on the same timeline in the first trialproc? My next question follows from this: once participants have completed either list1, 2 or 3, I then need the task to go back to the first screen (where they have the three response options). I would like to set up a counter on the screen that will continuously display cumulatively how many 'points' the participant has. Any tips on how to get started on this? Finally, I need to set up something that will enable me to deduct points from the participant at predetermined intervals (probably on a variable ratio schedule). Any help on any or all of these issues would be much appreciated!

This isn't documented in the User's Guide, possibly because it's new. Putting in "List1.Run c" instead of "List1.Run" should fix that (c is the default, current context). > > My next question follows from this: once participants have completed either > list1, 2 or 3, I then need the task to go back to the first screen (where they > have the three response options). > I would do this by placing the branch within a list that repeats the procedure containing the branch as many times as you want it to (or for however many seconds). > I would like to set up a counter on the screen that will continuously display > cumulatively how many 'points' the participant has.

If you know the program isn't going to be doing anything else at the time, you can just deduct points from an inline script. Otherwise, this may require more complex scripting, and I'm not entirely certain how well E-Prime handles background scripts.

This is my first message to the newsgroup: I hope you can help me!!! I am working on the moving windows experiment provided by PST. This version displays "active windows" (selected parts of the experimental sentence) and "inactive windows" (number of dashes equal to number of characters composing the corresponding phrase). By pressing the space bar you'll see the sentence progressively building. EXAMPLE: The poem ---------------------- --- --------------- --------- ----------------- -------- consists of long prose --- --------------- --------- ----------------- -------- ---------------------- and --------------- --------- ----------------- -------- ---------------------- --- delicate verses --------- ----------------- -------- ---------------------- --- --------------- dedicated ----------------- -------- ---------------------- --- --------------- --------- to Italian women. As you can see from this schematic example the script does not distinguish words from spaces and visualizes a ontinuous line of dashes for each inactive window, instead of segments of dashes corresponding to single words composing it. Example: The poem -------- -- ---- ----- --- -------- ------ --------- -- ------- ------ --- ---- consists of long prose --- -------- ------ --------- -- ------- ------ --- ---- -------- -- ---- ----- and -------- ------ --------- -- ------- ------ --- ---- -------- -- ---- ----- --- delicate verses --------- -- ------- ------ --- ---- -------- -- ---- ----- --- -------- ------ dedicated -- ------- ------ --- ---- -------- -- ---- ----- --- -------- ------ --------- to Italian women. For this reason subjects could be informed in advance of the number and lenght of successive parts of sentence to be presented and be biased by it. DEAR E-Primers CAN YOU HELP ME? IS THERE ANYBODY WHO HAVE ALREADY BUILT THIS KIND OF EXPERIMENT OR SOMETHING OF THE SORT? If you find it necessary, I could send you the script or the entire experiment.

I am using the following script after the first trialproc: If Allbuttons.RESP = "1" Then List1.Run ElseIf Allbuttons.RESP = "2" Then List2.Run Else List3.Run End If The problem is that I am getting an error message when I try to run it: "Factor error: Invalid context in list 1" (or list 2, or list 3, according to which response I make on the first part of the experiment). I'm not really sure what that error message means? When I delete my script, the whole thing works fine (it's just that then I get the three possible lists run sequentially). Perhaps I have not set-up the different levels of the task correctly - should the first part, and then the script, and then the three lists, all come on the same timeline in the first trialproc? My next question follows from this: once participants have completed either list1, 2 or 3, I then need the task to go back to the first screen (where they have the three response options). I would like to set up a counter on the screen that will continuously display cumulatively how many 'points' the participant has. Any tips on how to get started on this? Finally, I need to set up something that will enable me to deduct points from the participant at predetermined intervals (probably on a variable ratio schedule). Any help on any or all of these issues would be much appreciated!

This isn't documented in the User's Guide, possibly because it's new. Putting in "List1.Run c" instead of "List1.Run" should fix that (c is the default, current context). > > My next question follows from this: once participants have completed either > list1, 2 or 3, I then need the task to go back to the first screen (where they > have the three response options). > I would do this by placing the branch within a list that repeats the procedure containing the branch as many times as you want it to (or for however many seconds). > I would like to set up a counter on the screen that will continuously display > cumulatively how many 'points' the participant has.

To display it, you could use slides for your text displays and set a text box object in one corner that you could update from a script. > Finally, I need to set up something that will enable me to deduct points from > the participant at predetermined intervals (probably on a variable ratio > schedule). > I don't have any great ideas on this one, sorry. If you know the program isn't going to be doing anything else at the time, you can just deduct points from an inline script. Otherwise, this may require more complex scripting, and I'm not entirely certain how well E-Prime handles background scripts.

This is my first message to the newsgroup: I hope you can help me!!! I am working on the moving windows experiment provided by PST. This version displays "active windows" (selected parts of the experimental sentence) and "inactive windows" (number of dashes equal to number of characters composing the corresponding phrase). By pressing the space bar you'll see the sentence progressively building. EXAMPLE: The poem ---------------------- --- --------------- --------- ----------------- -------- consists of long prose --- --------------- --------- ----------------- -------- ---------------------- and --------------- --------- ----------------- -------- ---------------------- --- delicate verses --------- ----------------- -------- ---------------------- --- --------------- dedicated ----------------- -------- ---------------------- --- --------------- --------- to Italian women. As you can see from this schematic example the script does not distinguish words from spaces and visualizes a ontinuous line of dashes for each inactive window, instead of segments of dashes corresponding to single words composing it. Example: The poem -------- -- ---- ----- --- -------- ------ --------- -- ------- ------ --- ---- consists of long prose --- -------- ------ --------- -- ------- ------ --- ---- -------- -- ---- ----- and -------- ------ --------- -- ------- ------ --- ---- -------- -- ---- ----- --- delicate verses --------- -- ------- ------ --- ---- -------- -- ---- ----- --- -------- ------ dedicated -- ------- ------ --- ---- -------- -- ---- ----- --- -------- ------ --------- to Italian women. For this reason subjects could be informed in advance of the number and lenght of successive parts of sentence to be presented and be biased by it. DEAR E-Primers CAN YOU HELP ME? IS THERE ANYBODY WHO HAVE ALREADY BUILT THIS KIND OF EXPERIMENT OR SOMETHING OF THE SORT? If you find it necessary, I could send you the script or the entire experiment.

Myers) Date: Fri, 25 Oct 2002 14:15:20 +0800 Subject: measuring RT at offset of button press Message-ID: I would like to measure the time between the onset of a visual display and the OFFSET of a button press. Specifically, I plan to have sign language signers begin each trial with their hands on the button box or keyboard, and then lift their hands to initiate signing when a visual stimulus is displayed -- a kind of sign-language naming task. There doesn't seem to be anything built-in in E-Prime to make this easy to do, and I didn't see the relevant E-Basic command either. I know that keyboards at rest send a "rest" signal whose onset can be detected when a key is no longer pressed, so it should be doable. Any tips?
