From unixusik at gmail.com Tue Sep 3 21:25:28 2013 From: unixusik at gmail.com (unixusik at gmail.com) Date: Tue, 3 Sep 2013 14:25:28 -0700 Subject: the procedure loops and each next cycle of it reduces Message-ID: Hi everyone! I have been doing my research for the MA lately and I have problems with my procedure in e-prime. Like I wrote in the topic the procedure loops (against my intentions) and I don't know why. Also, I discovered after a while (when I questioned some respondents), the procedure reduces itself. I have two cycles of trail, and eight cycles of actual experiment. But only the part with the 8 cycles of the experiment loops. I think it might be connected with settings which I did for the *experiment' *s *selection overlap*. The selection is set on *offset* (order) and *subject* (order by). I did it because I wanted that every respondent starts on different part oh the cycles (because inside each cycle the order has to be sequential). But I am not sure that my settings are ok. I know what I want to achieve but somewhere I make a mistake. Do I think wright? Or maybe the problem is elsewhere? Thank you for your concern.

By "trail" I am not sure whether you mean (a) two practice cycles of the same task people will do in the actual experiment, which should occur first, or (b) the events ("trials") which occur within each cycle ("block") of the experiment And it is not entirely clear to me what the problem is, so I'm guessing a bit: If your actual experiment cycles are specified in 8 rows of a List object, selecting Offset, Order By Subject will start at a row number corresponding to the subject's number and then, proceed sequentially, after completing row #8 it will go back to row #1 and continue until your exit conditions are met. for example subject 3 would start at row 3, and so on. If subsequent cycles are reducing in number from what you intended maybe you need to double-check what your exit conditions are for the list. Finally, if your procedure isn't running as many trials as you think it should, a more reliable way to check on this is to look over your data files - your participants' self-reports after the study may not be the most accurate indication of what is actually being displayed. And if you look at the data files you may be able to explain more clearly what the problem is. I hope this helps!

In other words, a 1 moves backwards and a 2 moves forwards in the list. Below is the code I have that is not working. This occurs after I display the list item, so the list index has already advanced from 0 to 1. First, I get the current index (which works fine) then I check to see if it is greater than 1 (i.e. 2 or more) because I can't go backwards if I am at the first item. If the response = 1 then I set a new variable called NewIndex which is the currentindex -2 (because it has already advanced). Then I try to set the attribute value back to the new attribute value. But for some reason, that does not work. *How can I manually set the index of the current list?* ' My list is called ListOfComputers, and it is a list of computers (the task is computer shopping and subjects need to be able to move back and forth CurrentIndex = c.GetAttrib("ListOfComputers") 'Check to make sure we are far enough along the list to move backwards if CurrentIndex > 1 then if ShowMovie.RESP = 1 then 'Use -2 instead of minus one because the in line code occurs after the presentation slide so the list index has already advanced one space NewIndex = CurrentIndex - 2 c.SetAttrib "ListOfComputers", NewIndex end if end if ' This message box shows all of the variables with the values I want, it just does not actually change where on the list the next stimuli occurs.

Do you want to use the same order for all runs, or individualize the order for each run? If the former, then you might first put your List into the desired order, then run it in Offset order by Session (or Group), and use Session (or Group) to give the starting point.

Everything is working fine except that the previous total payoff cannot be remembered. This leads to a problem that every time a new card is selected, the total payoff is not added from the previous total payoff in the last trial but is added from $2000 in each trial. For example: Subjects start with $2000, Trial no.1: Won $ 100; Lost $0; so the Total is $2000+$100-$0= $2100 Trial no.2: Won $100; Lost$300; so the Total should be $2100+$100-$300=$1900 BUT, in my design, the Total is $2000+$100-$300=$1800 The script I wrote in InLine object of the Total payoff calculation is: If strHit="Image1" then List 1.run c Youwon=List1.GetCurrentAttrib ("Gaintrial") Youlost=List1.GetCurrentAttrib ("Losstrial") Total = 2000+Total+Youwon- Youlost ("Image1" is Deck A. "If strHit...means if the mouse click on Deck A, then run List1" "List 1" is the payment schedule of Deck A. "Youwon" is the amount of money won in each trial. "Youlost" is the amount fo money lost in each trial. "Gaintrial" is the attribute of List1 and is the winning schedule of Deck A. "Losstrial" is the attribute of List1 too and is the losing schedule of Deck A.) The amount of "Youwon" "Youlost" and "Total" are displayed on the feedback slide.

Message-ID: Hi all, I am creating a math task where the subject starts at a certain number and then subtracts 7 from each correct answer after that. If at any point in the subtraction process the subject gives the wrong answer, they begin at the original number and start all over again. I have got it to work where it will reset itself to the original number if a wrong answer is given. The practice round has four subtraction trials. However, this could easily become 5, 6, 7, etc trials if the subject gets any answer wrong. Thus, I've had to change the weight of the line to higher than four, or else after four trials, it will continue to the actual task. Here lies the problem: If I set the weight of the line to, say, 99 to account for wrong answer resets, it will force the subject to go through 99 subtraction trials. What I need it to do is after 4 right answers IN A ROW, continue to the task. If it's just an accuracy of four, it could be that they had to go back to the beginning four times and only got the first problem right each time. Thus, I need it to be four in a row to ensure that all four practice problems were answered correctly in sequential order. Does anyone have an idea of how to go about doing this?

S1_SlideText.BackColor = CColor(c.GetAttrib("color5") The error message is rather cryptic, but attribute "color5" is probably not defined in the current context. The List object contains "color?" attributes, but they don't contain any value. This often means that the attributes will be initialized using some inline script. However, if you look at the inline scripts, you can see that only color0, color1 and color2 are properly initialized. So, it seems that the original code used more color objects, but only 3 are used in this version (perhaps EP1 ignored this specific error). I think that you can solve it simply by removing the corresponding text objects from S1 (Text4, Text5, Text6) The same holds for S2.

When I open the xml I can read several tables. Although it is clear for me the meaning of onset to onset stats, onset delay stats, load time stats and experiment advisor finding, the last table is a little bit more difficult for me to understand: Experiment Advisor Modules. I was checking this table when I notice that most of the "problem" pointed out by this table was actually not relevant for my design. For example: "A visual object has its Stretch property set to Yes, which can cause display timing anomalies. Instead of using Stretch, consider editing the source material to match the size and proportions you want to display during the experiment". But no visual object in my experiment has stretch set to Yes. Or, again: "An object has its ClearAfter property set to Yes. ClearAfter is a deprecated property." This is not true for any of my object. So, how reliable is this table? Or maybe it just point out to POSSIBLE/LIKELY problems, without actually telling that you are incurring in one of those?

Try the following. Open a blank (Professional) experiment. Run it. Now look at the resulting ExperimentAdvisorReport.xml. See the Experiment Advisor Modules table? Does it include all the same items as before, even though the experiment is completely blank? Now disable some of the Experiment Advisor Modules. E.g., back in E-Studio, open the Experiment Object Properties, go to the Experiment Advisor tab, and disable "Use of ClearAfter" and "Use of Stretch". Run this, open the resulting ExperimentAdvisorReport.xml, and look at the Experiment Advisor Modules table. Do you see that "An object has its ClearAfter property set to Yes..." and "A visual object has its Stretch property set to Yes..." have both disappeared? From this evidence would you conclude that the Experiment Advisor Modules table tells you only what modules were enabled, and not what problems it found? Would you find this useful, because without this information you could not tell whether the lack of a warning only meant that that test was not run? As usual, do not take my word for any of this, test it out for yourself. I presented my answer this way because I need to stress that I do not have any inside knowledge about E-Prime, I simply figure it out exactly as I outlined above.

When the speed of the processor changes during > an experiment, this can interfere with E-Prime's timing. Therefore, > our developers have advised that some users with Windows XP may need > to switch over to the power management clock. I have attached a > document explaining how to make this change.

The document mentioned in the first paragraph includes instructions on how to switch the power management clock by editing boot.ini - I'm sure PST support will pass that information along to you in due course.

URL: From valerio.biscione at gmail.com Sun Sep 29 19:18:00 2013 From: valerio.biscione at gmail.com (Vaaal) Date: Sun, 29 Sep 2013 12:18:00 -0700 Subject: OnsetDelay and resolution problem? Message-ID: Hi, I am trying to design an experiment with precise timing measure. In order to make my problem clear, I have to give some details about my experiment. The order of the slide is CROSS - FP - LANDC - BLANK. The "timing important" frames, however, are only the last three. CROSS, FP and LANDC have "PreRelease" on (same as duration), the forth one doesn't have any prerelease. This is because the forth frame is a response frame, so the prerelease would be useless. The CROSS slide lasts 1000 milliseconds and has prerelease. FP duration, however, changes everytime (reading from an attribute "Duration" in the trialList). LANDC lasts 200 milliseconds. LANDC is a slide with an image object, and the image is in a directory specified by another attribute ("Image") in trialList. BLANK wait for the subject response. All the subject but LANDC are blank slides. The refreshAlignment is 50%. I am not interested in the timing of the CROSS slide. When I test my experiment on my office computer, the delay of FP and BLANK is around 0. The delay of LANDC is more variable (from -8 to 8, usually). The resolution in this computer (LCD) is 1920x1080 at 60Hz. I can accept a delay of max +-((1000/60))/2 ms. This means that for a refresh rate of 60hz, it is fine for me if the slide appears +- 8 ms before/after it is supposed to appear. Ifigured that FP and BLANK have a delay of 0 because the duration of their previous frame is a multiple of 16.66 ms. This seems to be the case: the CROSS slide duration, as said before, is 1000 (and 16.66*60 is 999.6). The duration of LANDC is 200 (16.66*12=199.92). However, LANDC doesn't have a delay of 0 because its previous frame, FP, doesn't have a multiple of the refresh rate (and I will not change that: the duration of FP changes constantly, according to the Duration attribute). The onsetDelay of 0 for the two frames is a lucky coincidence, and it is not required to be zero. As said before, it could be anything between +-(1000/refrashRate)/2. Now, MY PROBLEM IS that when I try the experiment on ANOTHER MACHINE the onsetDelay behave in a problematic way. When the resolution is 1600x1200 70Hz, I have almost perfect result when the refresh rate is 75Hz or lower. If the refresh rate is 85 or 100Hz, I have a OnsetDaly of approximately 11-12ms for all of the three slides (FP, LANDC and BLANK). Why this happens??? I could just stick with the 75Hz or lower rate, you could say. In my experiment, however, I highly prefer to use an high resolution. I tried a lot of different combination of resolution/refresh rate, and all the higher one lead to a dramatic (10/15 ms) increase of the onsetDelay for all the three slides. In particular I tried= 2048x1539, 75Hz and 60Hz 1920x1440, 85Hz, 75Hz, 70Hz and 60Hz. 1920x1200 70Hz and 60Hz. 1920x1080 70Hz I also tried with 1600x900. In this case, the results were good (around zero for CROSS and BLANK, within a reasonable range for LANC). So, it seems that, REGARDLESS of the refresh rate, at high resolution the onsetDelay increase. Does anyone have any idea why this happens? *Does anyone have any suggestion about HOW COULD I USE HIGH RESOLUTION WITHOUT ONSET DELAY?* Just for your information: the second monitor is a CRT Sony GDM-F520 (specs= http://www.docs.sony.com/release/specs/GDMF520_sp.pdf ). As you can notice, the recommended resolutions are 1920x1440 85Hz, 1800x1440 85Hz and 1600x1200 85Hz. For some reason, I cannot set the resolution to be 1800x1440. Anyway, as you can see I tried a lot of combination without success. I really need my resolution to be high (>= 1920x1200). The refresh rate is not so important, but since it is a CRT monitor I would prefer it to be higher than 72Hz. I really don't know what to do :( Any help is highly appreciated.

In-Reply-To: Message-ID: Valerio, What range of Durations do you use for FP? What happens to the OnsetDelay for LANDC if you set the Duration of FP to something long, e.g., 1000 ms? What happens to OnsetDelay of LANDC if Duration of FP is constant instead of varying? What happens to OnsetDelay of LANDC if it uses the same image every time instead of varying? Just trying to explore more factors to see what is critical here. Maybe start with a simple trial design with constant, long Duration for FP, and constant image for LANDC. If that fixes the OnsetDelay, then vary those factors systematically until it breaks again.

In-Reply-To: <5249c6a8.8570320a.0f74.74ecSMTPIN_ADDED_MISSING@gmr-mx.google.com> Message-ID: Hi David, thank you for your reply. Today I keep trying to solve it and finally I did it!! I am so happy about that :D So, if anyone had the same problem, this is the reason why this happens and the solution. It's extremely easy and trivial. The reason why with high resolution the onsetDelay is big it's because E-Prime has to "draw" more pixels. But if in your slide you just have a little stimulus in the middle (example a little black X, with a white background) you don't actually have to draw ALL the slide, but just some portion around the middle of the screen. To do that, I just had to adjust the value Height and Width of the Slide (to something like 10% and 10%). In this way a new slide will be put in front of the previous one, but the slide will be small and e-prime will not waste time drawing pixels that are the same as the previous slide. Since all my previous slides are white in the background, this works like a charm. In this way the software has to draw less pixel, and the onsetdelay decrease dramatically: I reached, with the right value of Duration (multiple of 1000/refreshHz) a onsetDelay of 0!!! You may have some problem if your slide have different backgrounds, but I assume that, knowing how it works, there is probably some way to go around the problem. David, thank you again for your help. Hope this is helpful. Valerio On Monday, 30 September 2013 19:44:51 UTC+1, McFarlane, David wrote: > > Valerio, > > What range of Durations do you use for FP?

I have been doing my research for the MA lately and I have problems with my procedure in e-prime. Like I wrote in the topic the procedure loops (against my intentions) and I don't know why. Also, I discovered after a while (when I questioned some respondents), the procedure reduces itself. I have two cycles of trail, and eight cycles of actual experiment. But only the part with the 8 cycles of the experiment loops. I think it might be connected with settings which I did for the *experiment' *s *selection overlap*. The selection is set on *offset* (order) and *subject* (order by). I did it because I wanted that every respondent starts on different part oh the cycles (because inside each cycle the order has to be sequential). But I am not sure that my settings are ok. I know what I want to achieve but somewhere I make a mistake. Do I think wright? Or maybe the problem is elsewhere? Thank you for your concern.

By "trail" I am not sure whether you mean (a) two practice cycles of the same task people will do in the actual experiment, which should occur first, or (b) the events ("trials") which occur within each cycle ("block") of the experiment And it is not entirely clear to me what the problem is, so I'm guessing a bit: If your actual experiment cycles are specified in 8 rows of a List object, selecting Offset, Order By Subject will start at a row number corresponding to the subject's number and then, proceed sequentially, after completing row #8 it will go back to row #1 and continue until your exit conditions are met. for example subject 3 would start at row 3, and so on. If subsequent cycles are reducing in number from what you intended maybe you need to double-check what your exit conditions are for the list. Finally, if your procedure isn't running as many trials as you think it should, a more reliable way to check on this is to look over your data files - your participants' self-reports after the study may not be the most accurate indication of what is actually being displayed. And if you look at the data files you may be able to explain more clearly what the problem is. I hope this helps!

If you set Max Count to 2, then EP will require and collect 2 responses, but will log only the final response.

In other words, a 1 moves backwards and a 2 moves forwards in the list. Below is the code I have that is not working. This occurs after I display the list item, so the list index has already advanced from 0 to 1. First, I get the current index (which works fine) then I check to see if it is greater than 1 (i.e. 2 or more) because I can't go backwards if I am at the first item. If the response = 1 then I set a new variable called NewIndex which is the currentindex -2 (because it has already advanced). Then I try to set the attribute value back to the new attribute value. But for some reason, that does not work. *How can I manually set the index of the current list?* ' My list is called ListOfComputers, and it is a list of computers (the task is computer shopping and subjects need to be able to move back and forth CurrentIndex = c.GetAttrib("ListOfComputers") 'Check to make sure we are far enough along the list to move backwards if CurrentIndex > 1 then if ShowMovie.RESP = 1 then 'Use -2 instead of minus one because the in line code occurs after the presentation slide so the list index has already advanced one space NewIndex = CurrentIndex - 2 c.SetAttrib "ListOfComputers", NewIndex end if end if ' This message box shows all of the variables with the values I want, it just does not actually change where on the list the next stimuli occurs. In other words it just keeps running through the list in the predefined order msgbox("CurrentIndex = " & CurrentIndex & " NewIndex = " & NewIndex &" ShowMovie.RESP = " & ShowMovie.RESP) -- You received this message because you are subscribed to the Google Groups "E-Prime" group.

For example, if they are shown an image they have seen before, the participant on the left would press "Q" while the participant on the right would press "N". If they hadn't seen the image before, the participant on the left would press "W" while the participant on the right would press "M". My problem is that my code makes it such that if one participant accidentally presses one key twice, their response is recorded twice and the other participant's response is not recorded. This data is thrown out. Is there some code to prevent this by recording only one keystroke from each half of the keyboard?

See https://groups.google.com/d/topic/e-prime/JtLh6DxqCbs for a bit more discussion. To get the the List into the desired order, I find Excel handy.

Everything is working fine except that the previous total payoff cannot be remembered. This leads to a problem that every time a new card is selected, the total payoff is not added from the previous total payoff in the last trial but is added from $2000 in each trial. For example: Subjects start with $2000, Trial no.1: Won $ 100; Lost $0; so the Total is $2000+$100-$0= $2100 Trial no.2: Won $100; Lost$300; so the Total should be $2100+$100-$300=$1900 BUT, in my design, the Total is $2000+$100-$300=$1800 The script I wrote in InLine object of the Total payoff calculation is: If strHit="Image1" then List 1.run c Youwon=List1.GetCurrentAttrib ("Gaintrial") Youlost=List1.GetCurrentAttrib ("Losstrial") Total = 2000+Total+Youwon- Youlost ("Image1" is Deck A. "If strHit...means if the mouse click on Deck A, then run List1" "List 1" is the payment schedule of Deck A. "Youwon" is the amount of money won in each trial. "Youlost" is the amount fo money lost in each trial. "Gaintrial" is the attribute of List1 and is the winning schedule of Deck A. "Losstrial" is the attribute of List1 too and is the losing schedule of Deck A.) The amount of "Youwon" "Youlost" and "Total" are displayed on the feedback slide. I am not sure where I am wrong, so I hope people who know how to solve this problem may help me out! Thank you very much!

Then it displays the recorded "score" to the user. What the original script does is this Dim percent as Integer Mouse.GetCursorPos ptPress.X, ptPress.Y percent = 100*((ptPress.X-VAS_SliderDummy.Left)/sw) ... and then it displays "percent" So the original script would display a score of "75" if the subject clicked on the 3/4th of the scale What i want to display is something like "7.5" instead of "75". I tried this : Dim percent as Integer Dim score as Double Mouse.GetCursorPos ptPress.X, ptPress.Y percent = 100*((ptPress.X-VAS_SliderDummy.Left)/sw) score=CInt(percent)/10 ... and then display "score" but then it would display something like "7.500121245" instead of just "7.5" how can i format the score so that it shows to 1 or 2 decimal places? thank you -- You received this message because you are subscribed to the Google Groups "E-Prime" group.

Message-ID: Hi all, I am creating a math task where the subject starts at a certain number and then subtracts 7 from each correct answer after that. If at any point in the subtraction process the subject gives the wrong answer, they begin at the original number and start all over again. I have got it to work where it will reset itself to the original number if a wrong answer is given. The practice round has four subtraction trials. However, this could easily become 5, 6, 7, etc trials if the subject gets any answer wrong. Thus, I've had to change the weight of the line to higher than four, or else after four trials, it will continue to the actual task. Here lies the problem: If I set the weight of the line to, say, 99 to account for wrong answer resets, it will force the subject to go through 99 subtraction trials. What I need it to do is after 4 right answers IN A ROW, continue to the task. If it's just an accuracy of four, it could be that they had to go back to the beginning four times and only got the first problem right each time. Thus, I need it to be four in a row to ensure that all four practice problems were answered correctly in sequential order. Does anyone have an idea of how to go about doing this?

S1_SlideText.BackColor = CColor(c.GetAttrib("color5") The error message is rather cryptic, but attribute "color5" is probably not defined in the current context. The List object contains "color?" attributes, but they don't contain any value. This often means that the attributes will be initialized using some inline script. However, if you look at the inline scripts, you can see that only color0, color1 and color2 are properly initialized. So, it seems that the original code used more color objects, but only 3 are used in this version (perhaps EP1 ignored this specific error). I think that you can solve it simply by removing the corresponding text objects from S1 (Text4, Text5, Text6) The same holds for S2.

I was checking this table when I notice that most of the "problem" pointed out by this table was actually not relevant for my design. For example: "A visual object has its Stretch property set to Yes, which can cause display timing anomalies. Instead of using Stretch, consider editing the source material to match the size and proportions you want to display during the experiment". But no visual object in my experiment has stretch set to Yes. Or, again: "An object has its ClearAfter property set to Yes. ClearAfter is a deprecated property." This is not true for any of my object. So, how reliable is this table? Or maybe it just point out to POSSIBLE/LIKELY problems, without actually telling that you are incurring in one of those?

Try the following. Open a blank (Professional) experiment. Run it. Now look at the resulting ExperimentAdvisorReport.xml. See the Experiment Advisor Modules table? Does it include all the same items as before, even though the experiment is completely blank? Now disable some of the Experiment Advisor Modules. E.g., back in E-Studio, open the Experiment Object Properties, go to the Experiment Advisor tab, and disable "Use of ClearAfter" and "Use of Stretch". Run this, open the resulting ExperimentAdvisorReport.xml, and look at the Experiment Advisor Modules table. Do you see that "An object has its ClearAfter property set to Yes..." and "A visual object has its Stretch property set to Yes..." have both disappeared? From this evidence would you conclude that the Experiment Advisor Modules table tells you only what modules were enabled, and not what problems it found? Would you find this useful, because without this information you could not tell whether the lack of a warning only meant that that test was not run? As usual, do not take my word for any of this, test it out for yourself. I presented my answer this way because I need to stress that I do not have any inside knowledge about E-Prime, I simply figure it out exactly as I outlined above.

URL: From valerio.biscione at gmail.com Sun Sep 29 19:18:00 2013 From: valerio.biscione at gmail.com (Vaaal) Date: Sun, 29 Sep 2013 12:18:00 -0700 Subject: OnsetDelay and resolution problem? Message-ID: Hi, I am trying to design an experiment with precise timing measure. In order to make my problem clear, I have to give some details about my experiment. The order of the slide is CROSS - FP - LANDC - BLANK. The "timing important" frames, however, are only the last three. CROSS, FP and LANDC have "PreRelease" on (same as duration), the forth one doesn't have any prerelease. This is because the forth frame is a response frame, so the prerelease would be useless. The CROSS slide lasts 1000 milliseconds and has prerelease. FP duration, however, changes everytime (reading from an attribute "Duration" in the trialList). LANDC lasts 200 milliseconds. LANDC is a slide with an image object, and the image is in a directory specified by another attribute ("Image") in trialList. BLANK wait for the subject response. All the subject but LANDC are blank slides. The refreshAlignment is 50%. I am not interested in the timing of the CROSS slide. When I test my experiment on my office computer, the delay of FP and BLANK is around 0. The delay of LANDC is more variable (from -8 to 8, usually). The resolution in this computer (LCD) is 1920x1080 at 60Hz. I can accept a delay of max +-((1000/60))/2 ms. This means that for a refresh rate of 60hz, it is fine for me if the slide appears +- 8 ms before/after it is supposed to appear. Ifigured that FP and BLANK have a delay of 0 because the duration of their previous frame is a multiple of 16.66 ms. This seems to be the case: the CROSS slide duration, as said before, is 1000 (and 16.66*60 is 999.6). The duration of LANDC is 200 (16.66*12=199.92). However, LANDC doesn't have a delay of 0 because its previous frame, FP, doesn't have a multiple of the refresh rate (and I will not change that: the duration of FP changes constantly, according to the Duration attribute). The onsetDelay of 0 for the two frames is a lucky coincidence, and it is not required to be zero. As said before, it could be anything between +-(1000/refrashRate)/2. Now, MY PROBLEM IS that when I try the experiment on ANOTHER MACHINE the onsetDelay behave in a problematic way. When the resolution is 1600x1200 70Hz, I have almost perfect result when the refresh rate is 75Hz or lower. If the refresh rate is 85 or 100Hz, I have a OnsetDaly of approximately 11-12ms for all of the three slides (FP, LANDC and BLANK). Why this happens??? I could just stick with the 75Hz or lower rate, you could say. In my experiment, however, I highly prefer to use an high resolution. I tried a lot of different combination of resolution/refresh rate, and all the higher one lead to a dramatic (10/15 ms) increase of the onsetDelay for all the three slides. In particular I tried= 2048x1539, 75Hz and 60Hz 1920x1440, 85Hz, 75Hz, 70Hz and 60Hz. 1920x1200 70Hz and 60Hz. 1920x1080 70Hz I also tried with 1600x900. In this case, the results were good (around zero for CROSS and BLANK, within a reasonable range for LANC). So, it seems that, REGARDLESS of the refresh rate, at high resolution the onsetDelay increase. Does anyone have any idea why this happens? *Does anyone have any suggestion about HOW COULD I USE HIGH RESOLUTION WITHOUT ONSET DELAY?* Just for your information: the second monitor is a CRT Sony GDM-F520 (specs= http://www.docs.sony.com/release/specs/GDMF520_sp.pdf ). As you can notice, the recommended resolutions are 1920x1440 85Hz, 1800x1440 85Hz and 1600x1200 85Hz. For some reason, I cannot set the resolution to be 1800x1440. Anyway, as you can see I tried a lot of combination without success. I really need my resolution to be high (>= 1920x1200). The refresh rate is not so important, but since it is a CRT monitor I would prefer it to be higher than 72Hz. I really don't know what to do :( Any help is highly appreciated.

In-Reply-To: Message-ID: Valerio, What range of Durations do you use for FP? What happens to the OnsetDelay for LANDC if you set the Duration of FP to something long, e.g., 1000 ms? What happens to OnsetDelay of LANDC if Duration of FP is constant instead of varying? What happens to OnsetDelay of LANDC if it uses the same image every time instead of varying? Just trying to explore more factors to see what is critical here. Maybe start with a simple trial design with constant, long Duration for FP, and constant image for LANDC. If that fixes the OnsetDelay, then vary those factors systematically until it breaks again. In addition, take a look at the new GeneratePreRun feature, in particular the "TopOfProcedure" setting. ----- David McFarlane E-Prime training online: http://psychology.msu.edu/Workshops_Courses/eprime.aspx Twitter: @EPrimeMaster (https://twitter.com/EPrimeMaster) /---- Stock reminder: 1) I do not work for PST. 2) PST's trained staff take any and all questions at http://support.pstnet.com/e%2Dprime/support/login.asp , and they strive to respond to all requests in 24-48 hours, so make full use of it. 3) In addition, PST offers several instructional videos on their YouTube channel (http://www.youtube.com/user/PSTNET ). 4) If you do get an answer from PST staff, please extend the courtesy of posting their reply back here for the sake of others. \---- At 9/29/2013 03:18 PM Sunday, Vaaal wrote: >Hi, >I am trying to design an experiment with precise timing measure.

In-Reply-To: <5249c6a8.8570320a.0f74.74ecSMTPIN_ADDED_MISSING@gmr-mx.google.com> Message-ID: Hi David, thank you for your reply. Today I keep trying to solve it and finally I did it!! I am so happy about that :D So, if anyone had the same problem, this is the reason why this happens and the solution. It's extremely easy and trivial. The reason why with high resolution the onsetDelay is big it's because E-Prime has to "draw" more pixels. But if in your slide you just have a little stimulus in the middle (example a little black X, with a white background) you don't actually have to draw ALL the slide, but just some portion around the middle of the screen. To do that, I just had to adjust the value Height and Width of the Slide (to something like 10% and 10%). In this way a new slide will be put in front of the previous one, but the slide will be small and e-prime will not waste time drawing pixels that are the same as the previous slide. Since all my previous slides are white in the background, this works like a charm. In this way the software has to draw less pixel, and the onsetdelay decrease dramatically: I reached, with the right value of Duration (multiple of 1000/refreshHz) a onsetDelay of 0!!! You may have some problem if your slide have different backgrounds, but I assume that, knowing how it works, there is probably some way to go around the problem. David, thank you again for your help. Hope this is helpful. Valerio On Monday, 30 September 2013 19:44:51 UTC+1, McFarlane, David wrote: > > Valerio, > > What range of Durations do you use for FP?
