Group: Forum Members Posts: 11, Visits: 71	Hello! I'm trying to build an IAPS procedure. It basically goes: Slide1<5 seconds>: "Get Ready to Rate the Next Slide" Slide2<6 seconds>: Display a random picture from sets of Pleasant, Neutral and Unpleasant Slide3: A page with a slider to rate Arousal Slide4: A page with a slider to rate Valence Slide5: A page with a slider to rate Dominance Repeat this 60 times. I'm a bit stuck :(. Here are my issues: 1. I don't know how to organize the trials within the blocks to display a set of 3 pages of sliders after every picture display trial. (I tried to have the trials put in a list) 2. I want to be able to record what picture category and picture they are rating 3. I want to be able to record in what order they viewed the pictures Here's my code so far: <block IAPS> /trials = [1,3,5,7,9=IAPSdisplayPicture; 2,4,6,8,10 = list.SAM1Ratings] </block> **Display the picture <trial IAPSdisplayPicture> / stimulustimes = [1= IAPSinstruct; 5000=noreplace(IAPSPleasantpic, IAPSNeutralpic)] / timeout = 11000 </trial> <text IAPSinstruct> /items = ("Get ready to rate the next slide") / position = (50%,50%) </text> <picture IAPSPleasantPic> /items = Pleasant /position = (50%,50%) /select = sequence </picture> <picture IAPSNeutralPic> /items = Neutral /position = (50%,50%) /select = sequence </picture> *****SAM***** <list SAM1Ratings> /items = (SAMA1, SAMV1, SAMD1) / selectionmode = sequence </list> Maybe I should have a survey? but they don't count as trial objects* <survey SAM1Ratings> / pages = [1=SAMA1; 2=SAMV1; 3=SAMD1] / showbackbutton = false </survey> ******Pages******** <surveypage SAMA1> / stimulustimes = [0=SAMAinstruct, SAM.A1, SAM.A2, SAM.A3, SAM.A4, SAM.A5, SAM.A6, SAM.A7, SAM.A8, SAM.A9] / questions = [1=SAMA1] / showquestionnumbers = false </surveypage> <surveypage SAMV1> / stimulustimes = [0=SAMVinstruct, SAM.V1, SAM.V2, SAM.V3, SAM.V4, SAM.V5, SAM.V6, SAM.V7, SAM.V8, SAM.V9] / questions = [1=SAMV1] / showquestionnumbers = false </surveypage> <surveypage SAMD1> / stimulustimes = [0=SAMDinstruct, SAM.D1, SAM.D2, SAM.D3, SAM.D4, SAM.D5, SAM.D6, SAM.D7, SAM.D8, SAM.D9] / questions = [1=SAMD1] / showquestionnumbers = false </surveypage> *Slider questions. Will Need as many Sliders as there are pictures**** <slider SAMA1> / range = (0, 20) / increment = 1 / position = (10%,55%) / showticks = false / showtooltips = false / slidersize = (100%, 10%) </slider> <slider SAMV1> / range = (0, 20) / increment = 1 / position = (10%,55%) / showticks = false / showtooltips = false / slidersize = (100%, 10%) </slider> <slider SAMD1> / range = (0, 20) / increment = 1 / position = (10%,55%) / showticks = false / showtooltips = false / slidersize = (100%, 10%) </slider> <text SAMAinstruct> / items = ("Please rate your arousal") / size = (500px, 200px) / fontstyle = ("Verdana", 14pt) / position = (50%,40%) </text> <text SAMVinstruct> / items = ("Please rate your valence") / size = (500px, 200px) / fontstyle = ("Verdana", 14pt) / position = (50%,40%) </text> <text SAMDinstruct> / items = ("Please rate your dominance") / size = (500px, 200px) / fontstyle = ("Verdana", 14pt) / position = (50%,40%) </text>

Group: Administrators Posts: 13K, Visits: 108K	If you wanted to select surveypages via a <list>, you would have to use correct syntax: <block myblock> / trials = [1-3=list.splist] </block> <list splist> / items = (surveypage.a, surveypage.b, surveypage.c) / selectionmode = sequence </list> <surveypage a> / caption = "A" </surveypage> <surveypage b> / caption = "B" </surveypage> <surveypage c> / caption = "C" </surveypage> But there should be no reason to do so. You should simply do <block IAPS> /trials = [1-5=sequence(IAPSdisplayPicture, SAMA1, SAMV1, SAMD1)] </block> The order of pictures will obviously be reflected by the respective stimulusitem and stimulusnumber columns in the data file.

Group: Forum Members Posts: 11, Visits: 71	Thank you Dave, I feel like kicking myself, that seems obvious. So, here are a few more questions related to this: I have a set of IAPS pictures that are supposed to be fully counterbalanced on one of three psuedorandomized orders (Using van Carstenson's MIX software) across two groups of ethnicities. I currently have an <item IAPS.pictures> which stores all of my picture filenames. 1. How do I construct these orders in Inquisit? It seems unreasonable to build 3 <item> tags for each order, can I make a list instead? 2. I want the 3 SAM questions displayed after every picture, but I want separate responses for every picture. The SAM questions are each 1 sliders and a set of 9 pictures contained in a surveypage. If I have 60 IAPS pictures, Do I have to have a new slider and surveypage for all 60 picture stimuli? 3. <item> tag can only hold stimuli, and surveypage is a trial element. Can I hold all of my surveypages in an <item> or <list> and how do I pair each SAM question with its corresponding picture? 4. How do I ensure that my 3 orders are fully counterbalanced across the two groups? Thank you again!

There are any number of ways to do this. Using <list>s certainly is one of the possibilities. > 2.

If I have 60 IAPS pictures, Do I have to have a new slider and surveypage for all 60 picture stimuli?[/quote] Depends on how exactly you want to display the pictures on the respective surveypages. If you use <image>, then yes, you need separate surveypages. If you use <picture>, then not necessarily (you already know how to pair various stimuli). > 3. <item> tag can only hold stimuli, and surveypage is a trial element. Can I hold all of my surveypages in an <item> or <list> and how do I pair each SAM question with its corresponding picture?[/quote] Selecting surveypages via a <list> has already been covered in this very thread above. Surveypages are not stimulus items, so there is no use for <item> elements here. Pairing stimuli has also been covered in previous conversations and still works exactly the same. > 4. How do I ensure that my 3 orders are fully counterbalanced across the two groups?[/quote] Again, depends. In general you counterbalance conditions between subjects via <expt> elements' /subjects and /groupassignment attributes. Edited 12 Years Ago by Dave

Group: Administrators Posts: 13K, Visits: 108K	To add a few more concrete hints / ideas, here's a short self-contained example. Suppose I have six items A to F and want to display them in 4 different pre-determined orders to participants (between subjects). Then I could do something along the lines of <expressions> / mysequence = if (values.sequencenumber == 1) sequence(2,4,6,1,3,5) else if (values.sequencenumber == 2) sequence(1,3,5,2,4,6) else if (values.sequencenumber == 3) sequence(1,2,3,4,5,6) else if (values.sequencenumber == 4) sequence(6,5,4,3,2,1) else 1 </expressions> <values> / sequencenumber = 1 / currentitem = 1 </values> <text mytext> / items = myitems / select = values.currentitem </text> <item myitems> / 1 = "A" / 2 = "B" / 3 = "C" / 4 = "D" / 5 = "E" / 6 = "F" </item> <trial mytrial> / ontrialbegin = [values.currentitem = expressions.mysequence] / stimulusframes = [1=mytext] / validresponse = (57) </trial> <block myblock> / trials = [1-6=mytrial] </block> <expt> / onblockbegin = [values.sequencenumber = 1] / blocks = [1=myblock] / subjects = (1 of 4) </expt> <expt> / onblockbegin = [values.sequencenumber = 2] / blocks = [1=myblock] / subjects = (2 of 4) </expt> <expt> / onblockbegin = [values.sequencenumber = 3] / blocks = [1=myblock] / subjects = (3 of 4) </expt> <expt> / onblockbegin = [values.sequencenumber = 4] / blocks = [1=myblock] / subjects = (4 of 4) </expt> Please note that there probably are a dozen or more other ways to achieve the same.

Group: Forum Members Posts: 11, Visits: 71	Thanks Dave, I think that clears up the confusion I had with the counterbalancing orders! I'm still confused with how to set up multiple identically formatted surveypages so I tried a couple of things I have 60 <slider> items that correspond to each IAPS picture, and I have an <item> that has the names of all 60 of these sliders. I'm attempting to have the surveypage dynamically pull up the slider name from an <item> corresponding to the picture stimulus that was just presented to the subject. I tried using the .items.index property and the item(index) function and neither seem to be working. May be a formatting issue? I tried with quotes and without quotes, with <% %> and without. Any hints here? My partial code: <block IAPSb1> /ontrialbegin = [values.currentitem = expressions.iapssequence] /trials = [1-12=sequence(IAPSdisplayPicture, SAMV, SAMA, SAMD)] </block> ********Pages********** <surveypage SAMA> / stimulustimes = [0=SAMAinstruct, SAM.A1, SAM.A2, SAM.A3, SAM.A4, SAM.A5, SAM.A6, SAM.A7, SAM.A8, SAM.A9] / questions = [1= "<% item.iaps.SAMArousal.item(values.currentitem) %>"] / showquestionnumbers = false / showpagenumbers = false / finishlabel = "Next" </surveypage> <surveypage SAMV> / stimulustimes = [0=SAMVinstruct, SAM.V1, SAM.V2, SAM.V3, SAM.V4, SAM.V5, SAM.V6, SAM.V7, SAM.V8, SAM.V9] / questions = [1= "<% item.iaps.SAMValence.item(values.currentitem) %>"] / showquestionnumbers = false / showpagenumbers = false / finishlabel = "Next" </surveypage> <surveypage SAMD> / stimulustimes = [0=SAMDinstruct, SAM.D1, SAM.D2, SAM.D3, SAM.D4, SAM.D5, SAM.D6, SAM.D7, SAM.D8, SAM.D9] / questions = [1= "<% item.iaps.SAMDominance.item(values.currentitem) %>"] / showquestionnumbers = false / showpagenumbers = false / finishlabel = "Next" </surveypage>

Group: Administrators Posts: 13K, Visits: 108K	Sun, <slider> elements aren't stimulus items either, so / questions = [1= "<% item.iaps.SAMArousal.item(values.currentitem) %>"] is (a) invalid syntax on multiple levels and (b) there --again -- is no use for <item> elements in this context. Example of one conceivable proper approach: <expressions> / mysequence = sequence(2,1,3) </expressions> <values> / currentitem = 1 </values> <block myblock> / trials = [1-3=sequence(mytrial, page1, page2)] </block> <trial mytrial> / ontrialbegin = [values.currentitem = expressions.mysequence] / stimulusframes = [1=mytext] / trialduration = 2000 </trial> <text mytext> / items = ("A", "B", "C") / select = values.currentitem </text> <surveypage page1> / questions = [1=slider1] / showpagenumbers = false </surveypage> <surveypage page2> / questions = [1=slider2] / showpagenumbers = false </surveypage> <slider slider1> / caption = "<% list.slider1caption.nextvalue %>" </slider> <slider slider2> / caption = "<% list.slider2caption.nextvalue %>" </slider> <list slider1caption> / items = ("A1", "B1" "C1") / selectionmode = values.currentitem </list> <list slider2caption> / items = ("A2", "B2" "C2") / selectionmode = values.currentitem </list>
