From w.spooren at let.vu.nl Thu Oct 11 15:36:39 2001 From: w.spooren at let.vu.nl (W. Spooren) Date: Thu, 11 Oct 2001 16:36:39 +0100 Subject: presenting probes during text presentation Message-ID: Hi, We're trying to develop an experiment in which we use e-prime to present longer texts (say 300+ words) sentence by sentence. A sentence remains on the screen until the participant presses a key, and the next sentence appears. After particular sentences participants are asked to verify whether a probe word was or was in the previous text. Particularly the presentation of the probe words gets us into trouble. Does anyone have a model experiment from which we can copy (parts)? Thanks a million.

I've set up a page of E-Prime sample scripts that we're going to be adding to over time -- mostly simple implementations to fix common problems. It's at: http://step.psy.cmu.edu/script_samples/ Let me know if you think there are errors in the scripts or on the page. Also, I'm going to be adding to it from the archives we already have, but if you haven't sent in scripts for the STEP project and would like something to be included in these script samples, please let me know. This, of course, brings me to the subject of this email (in case the problem hasn't already been solved through personal email). I've put together a simple experiment that presents sentences and presents a probe depending on whether there is one associated with the sentence or not. Since I'm not sure what the precise problem in this study is, I'm not certain I've solved it in this script -- please let me know. I did not implement the text-length parameters, but I thought perhaps that the script I created was extensible to long texts (as long as they are separated into lists by passage, or there's a separate probe for each sentence position). The E-Prime file is located at: http://step.psy.cmu.edu/script_samples/Sentence_Probe.zip Thanks, Susan Campbell Research Assistant Carnegie Mellon -----Original Message----- Date: Thu, 11 Oct 2001 16:36:39 +0100 Reply-To: "W.

When the SR box is unplugged, the problem goes away. This has happened several times at my institution. I was wondering if anyone has seen this problem. Is this a known bug? Is it something that we're doing incorrectly? Is there a solution for this problem? Thanks for your time. Ted Steger, M.S.

You can set runtime display resolution and color depth. Some additional advice... If you are loading bitmaps and need fast performance make sure your bitmaps are only as large as you really need them, e.g. you can run the experiment in 1024x768 to get a crisp resolution, but if the stimulus image is only in the center 25% of the screen you should clip the picture down to that size. Likewise you can look into reducing the Frame size of the ImageDisplay object and/or try changing BackStyle property to "transparent" (to prevent an initial clear operation being performed within the display), e.g. if one bitmap completely overwrites the previous, then you can improve the throughput of the presentation sequence by using "transparent" vs "opaque". Hope that helps. Anthony P.
