Date: Wed, 2 Jun 2004 20:06:51 +0100 Subject: moving an object around a simple maze Message-ID: Hi I have a paradigm where a picture of a mouse appears in one of four rooms and a subject has to guide the mouse to one of the other rooms. I have done this before simply using key presses to indicate the destinations (e.g. A, B, C or D) but now we wish to 'navigate' the mouse from room to room using the mouse. What would be the best strategy for implementing this? The maze is very simple, essentially consisting of 4 quadrants with a gap in the dividing walls at the centre of the screen. Is there any sort of collision detection available in E-Prime, or would it be a case of comparing the mouse coordinates with the known position of the room dividers? Any suggestions for a strategy for moving the mouse around the maze will be gratefully received.

You should either change the settings on the Display Device in your E-Prime experiment to match your desktop, OR alternatively change your desktop to match the settings in E-Prime. If you have never changed the settings for the Display Device in E-Prime they are probably still set to a default of 640x480 16-bit color (which is probably not what you are running on the desktop and likewise not what the projector is synced to). Depending on the video card you are using you may also have the option under advanced settings for your card to explicitly set the preferred color depth and refresh rate for each resolution supported by your card.

While putting together a new experiment, I've discovered that even though SoundOuts work just fine before Eprime has been suspended, they don't work after Eprime has resumed. The bug manifests in a couple different ways. If the wav's filename is supplied by an attribute reference, I get the following error when the script reaches the SoundOut: Run-time Error (Line 300) 18005: Cannot load sound file "filename.wav" Filename is not set On the other hand, if I enter the wav's filename directly into the SoundOut's filename field, I don't get an error message and the EDAT file confirms that Eprime executed the SoundOut's script, but I don't get a sound. Has anyone come across this problem? Any suggestions? Thanks, Jeff *************************************************** Jeff T.

At this point, the tools needed for porting are simply not available. If you use E-Prime with the USB copy protection key, you can download the "Mac" version of the hardware key driver (and then turn off hardware acceleration if needed) to install under Virtual PC. The site www.ealaddin.com/support/hasp/enduser.asp#latestdd will direct you to the page where you can find the latest driver for your hardware and decide which one to download. Please keep in mind, however, that we do not offer support for E-Prime on Virtual PC. Attempting to install and run under VirtualPC is unstable at best, and PST does not support installation or use of the software under this environment. We do stress that you cannot subject data collect on Virtual PC, since it is emulated on the Mac. However, if you want to develop on Virtual PC you can do so by using the hardware key driver above. ---------------------------------------------------------------------------- -----Original Message----- From: eprime at mail.talkbank.org [mailto:eprime at mail.talkbank.org] On Behalf Of Cynthia J DeVore Sent: 10 June 2004 14:16 To: Matthew Paul; eprime at mail.talkbank.org Subject: Re: E-Prime running on a Mac under Virtual PC?

This permits for eight output pins on D0-D7 and is typically at address hex 378. Then, you can read from the parallel port's status register from bits S3-S6 and inverted S7 bits. If you require to be able to read more bits or do not want to deal with the inverted bits the standard port provides, you can have E-Prime work with a little script to program the parallel port to work in Bi-Directional mode. By doing so, the Data bits D0-D7 would act as inputs. This would work best if you only needed to read or write in an experiment. If you need to consistently read and write in an experiment, then sticking with the standard mode would probably be the best because it would require little scripting. If you only need to occasionlly bounce between reading and writing, then you can go with the bi-directional mode. I would encourage you to contact PST tech support and request the example scripting they have available. The experiment they have has all of the script behind the scenes and you only have to call "ConfigurePortForOutput" or "ConfigurePortForInput" in and Inline. -Brandon __________________________________ Do you Yahoo!?

I'm presenting text stimuli, which have to be on screen for 6 seconds, and are then cleared - no problem. What is causing the problem is that I need to be able to get the response during and after the stimulus, i.e. the stimulus will be cleared, but the program will not proceed on to the next stimulus until a response has been made, and no time limit must be set for the response to occur in. I think I'm being extremely dense, but when trying to script this, I've tried using a slide, but I can't seem to set durations of the sub-components, so would I be best just using a text object with unlimited duration, and then an inline script to clear the display after 6000ms? Thanks for any help Eddie Dubourg Computing/Technical support Officer Theoretical and Applied Linguistics University of Edinburgh.

You should also set the Terminate option to Jump and specify a label name as a jump destination. Set Clear After = No e.g. rather than having this object clear itself, you will use a second object to clear the stimulus after the 6000ms expires. You then need to add new object immediately after the stimulus object that does NOT accept a response but which does have an infinite Duration. Sounds like you can just use another TextDisplay object with its background color set to match that of the first object. After this object you then place your Label object. The way this will work is if the response comes in within the 6000ms it will be accepted and the system will skip the next object by jumping over it to the label you have created. If the response comes in after 6000ms then you will again jump to the label and thus terminate the second object. If no response comes in within the first 6000ms then the first object will end and the second object will clear the stimulus from the screen when it runs. You should be able to setup this type of structure without using any Inline script.

I'm writing to ask whether anybody knows of a way to generate visual noise using E-Prime? I'm designing a word-by-word reading task. In one condition, I'd like the words to be unobscured (legible, easy to read). In another condition, I'd like to mask the words with something like 2-dimensional "television snow" (making the words more difficult to read). Adobe Photoshop has a Gaussian noise function that I've used successfully (this requires manually generating new noise maskers for every participant). But I'm wondering whether E-Prime can do something like generate a new visual masker for every trial, perhaps using a draw command with a Slide object???

Even though I read the book I found it hard to set up multiple random lists. (Once I had it figured out, it was easy.)

I have done this before simply using key presses to indicate the destinations (e.g. A, B, C or D) but now we wish to 'navigate' the mouse from room to room using the mouse. What would be the best strategy for implementing this? The maze is very simple, essentially consisting of 4 quadrants with a gap in the dividing walls at the centre of the screen. Is there any sort of collision detection available in E-Prime, or would it be a case of comparing the mouse coordinates with the known position of the room dividers?

You should either change the settings on the Display Device in your E-Prime experiment to match your desktop, OR alternatively change your desktop to match the settings in E-Prime. If you have never changed the settings for the Display Device in E-Prime they are probably still set to a default of 640x480 16-bit color (which is probably not what you are running on the desktop and likewise not what the projector is synced to). Depending on the video card you are using you may also have the option under advanced settings for your card to explicitly set the preferred color depth and refresh rate for each resolution supported by your card.

While putting together a new experiment, I've discovered that even though SoundOuts work just fine before Eprime has been suspended, they don't work after Eprime has resumed. The bug manifests in a couple different ways. If the wav's filename is supplied by an attribute reference, I get the following error when the script reaches the SoundOut: Run-time Error (Line 300) 18005: Cannot load sound file "filename.wav" Filename is not set On the other hand, if I enter the wav's filename directly into the SoundOut's filename field, I don't get an error message and the EDAT file confirms that Eprime executed the SoundOut's script, but I don't get a sound. Has anyone come across this problem? Any suggestions? Thanks, Jeff *************************************************** Jeff T.

At this point, the tools needed for porting are simply not available. If you use E-Prime with the USB copy protection key, you can download the "Mac" version of the hardware key driver (and then turn off hardware acceleration if needed) to install under Virtual PC. The site www.ealaddin.com/support/hasp/enduser.asp#latestdd will direct you to the page where you can find the latest driver for your hardware and decide which one to download. Please keep in mind, however, that we do not offer support for E-Prime on Virtual PC. Attempting to install and run under VirtualPC is unstable at best, and PST does not support installation or use of the software under this environment. We do stress that you cannot subject data collect on Virtual PC, since it is emulated on the Mac. However, if you want to develop on Virtual PC you can do so by using the hardware key driver above. ---------------------------------------------------------------------------- -----Original Message----- From: eprime at mail.talkbank.org [mailto:eprime at mail.talkbank.org] On Behalf Of Cynthia J DeVore Sent: 10 June 2004 14:16 To: Matthew Paul; eprime at mail.talkbank.org Subject: Re: E-Prime running on a Mac under Virtual PC?

This permits for eight output pins on D0-D7 and is typically at address hex 378. Then, you can read from the parallel port's status register from bits S3-S6 and inverted S7 bits. If you require to be able to read more bits or do not want to deal with the inverted bits the standard port provides, you can have E-Prime work with a little script to program the parallel port to work in Bi-Directional mode. By doing so, the Data bits D0-D7 would act as inputs. This would work best if you only needed to read or write in an experiment. If you need to consistently read and write in an experiment, then sticking with the standard mode would probably be the best because it would require little scripting. If you only need to occasionlly bounce between reading and writing, then you can go with the bi-directional mode. I would encourage you to contact PST tech support and request the example scripting they have available. The experiment they have has all of the script behind the scenes and you only have to call "ConfigurePortForOutput" or "ConfigurePortForInput" in and Inline. -Brandon __________________________________ Do you Yahoo!?

I'm presenting text stimuli, which have to be on screen for 6 seconds, and are then cleared - no problem. What is causing the problem is that I need to be able to get the response during and after the stimulus, i.e. the stimulus will be cleared, but the program will not proceed on to the next stimulus until a response has been made, and no time limit must be set for the response to occur in. I think I'm being extremely dense, but when trying to script this, I've tried using a slide, but I can't seem to set durations of the sub-components, so would I be best just using a text object with unlimited duration, and then an inline script to clear the display after 6000ms?

From anthony.zuccolotto at pstnet.com Mon Jun 28 20:56:28 2004 From: anthony.zuccolotto at pstnet.com (Tony Zuccolotto) Date: Mon, 28 Jun 2004 16:56:28 -0400 Subject: Getting response after stimulus has been cleared Message-ID: Eddie, I would recommend setting the Time Limit on the response input mask to (infinite) but setting the Duration of the stimulus object to 6000ms (it won't matter what type of object you are using - either a text or slide display). You should also set the Terminate option to Jump and specify a label name as a jump destination. Set Clear After = No e.g. rather than having this object clear itself, you will use a second object to clear the stimulus after the 6000ms expires. You then need to add new object immediately after the stimulus object that does NOT accept a response but which does have an infinite Duration. Sounds like you can just use another TextDisplay object with its background color set to match that of the first object. After this object you then place your Label object. The way this will work is if the response comes in within the 6000ms it will be accepted and the system will skip the next object by jumping over it to the label you have created. If the response comes in after 6000ms then you will again jump to the label and thus terminate the second object. If no response comes in within the first 6000ms then the first object will end and the second object will clear the stimulus from the screen when it runs. You should be able to setup this type of structure without using any Inline script.

I'm writing to ask whether anybody knows of a way to generate visual noise using E-Prime? I'm designing a word-by-word reading task. In one condition, I'd like the words to be unobscured (legible, easy to read). In another condition, I'd like to mask the words with something like 2-dimensional "television snow" (making the words more difficult to read). Adobe Photoshop has a Gaussian noise function that I've used successfully (this requires manually generating new noise maskers for every participant). But I'm wondering whether E-Prime can do something like generate a new visual masker for every trial, perhaps using a draw command with a Slide object???

Even though I read the book I found it hard to set up multiple random lists. (Once I had it figured out, it was easy.) I also ran one where I needed to establish a random order for each subject, then repeat that same "random" order later in the experiment. Wound up solving that problem awkwardly, then got great suggestions from this list.
