Group: Forum Members Posts: 17, Visits: 153	Hi, I need to show one image every trial with to likert scales for two different questions on the same screen. Is it possible to do this? Besides, I have three different types of images (Positive Emotional State, Neutral Emotional State and Negative Emotional State). I need to show these images in random order, being sure that more than two images of the same emotional state will never be displayed consecutively. This is de code I have so far: <values> /responsestoring = false </values> <defaults> /screencolor = (255, 255, 255) /font = ("Helvetica", -16, 700, 0, 49) /txbgcolor=(255,255,255) </defaults> <expt> / preinstructions = (intro) / blocks = [1 = MSDFE] / postinstructions = (end) </expt> <block MSDFE> / preinstructions = (instruccionesMSDFE) /trials = [1-15 = likertMSDFE] /recorddata = true / bgstim = (comoCreeTxt) </block> <likert likertMSDFE> / anchors = [1="Negativo"; 5 = "Neutro"; 9="Positivo"] / stimulusframes = [1-15 = pictureMSDFE] / mouse = false / numpoints = 9 / position = (50, 90) </likert> <text comoCreeTxt> /items = comoCree /position = (50, 10) </text> <item comoCree> /1 = "Â¿CÃ³mo cree que se estÃ¡ sintiendo esta persona?" </item> <picture pictureMSDFE> /items = item_MSDFE /select = noreplace /size = (60%, 60%) /position = (50%, 50%) </picture> <item item_MSDFE> /1 = "MSDFE1/negativoHombre-414M.tif" /2 = "MSDFE1/negativoHombre-425M.tif" /3 = "MSDFE1/negativoHombre-426M.tif" /4 = "MSDFE1/negativoMujer-274.tif" /5 = "MSDFE1/negativoMujer-453M.tif" /6 = "MSDFE1/neutralHombre-20.tif" /7 = "MSDFE1/neutralHombre-23.tif" /8 = "MSDFE1/neutralMujer-27.tif" /9 = "MSDFE1/neutralMujer-46M.tif" /10 = "MSDFE1/neutralMujer45M.tif" /11 = "MSDFE1/positivoHombre-422M.tif" /12 = "MSDFE1/positivoHombre-442M.tif" /13 = "MSDFE1/positivoMujer-452M.tif" /14 = "MSDFE1/positivoMujer-462M.tif" /15 = "MSDFE1/positivoMujer-472M.tif" </item> ************** INSTRUCTION DEFINITION AND INSTRUCTION PAGES **************** <instruct> /windowsize = (65%, 85%) / fontstyle = ("Helvetica", 2.5%, false, false, false, false, 5, 1) / txcolor = (black) / finishlabel = "Presiona la tecla Enter continuar" / nextkey = (28) / nextlabel = "Presiona la tecla Enter para continuar" / prevkey = (57) / prevlabel = "Presiona la barra espaciadora para volver atrÃ¡s" </instruct> <page intro> El objetivo de este experimento es determinar tu capacidad de atenciÃ³n a una serie de estÃmulos visuales que verÃ¡s a continuaciÃ³n.^^ Sin embargo, antes de continuar te haremos algunas preguntas. Recuerda que todas las respuestas son anÃ³nimas. AsÃ que te puedes sentir en libertad de marcar las respuestas que realmente describen como te sientes. Ademas tus respuestas son confidenciales y te serÃ¡ asignado un cÃ³digo que no estarÃ¡ relacionado con tu nombre.^^ Cuando estÃ©s listo, presiona la tecla Enter para comenzar. </page> <page end> AquÃ termina el experimento. !Gracias por particiar! </page> <page instruccionesMSDFE> A continuaciÃ³n verÃ¡s una serie de fotografÃas de diferentes personas. DeberÃ¡s indicar como crees que se estÃ¡n sintiendo segÃºn su expresiÃ³n facial. Por favor asigna un nÃºmero entre 1 y 9 a cada imagen usando la escala que se encuentra en la parte inferior de la pantalla.^^ Cuando hayas decidido tu respuesta, marca la opciÃ³n correspondiente usando los nÃºmeros del teclado, y despuÃ©s presiona Enter.^^ "1" significa ESTADO EMOCIONAL MUY NEGATIVO^^ "2" significa ESTADO EMOCIONAL MODERADAMENTE NEGATIVO^^ "3" significa ESTADO EMOCIONAL POCO NEGATIVO^^ "4" significa ESTADO EMOCIONAL NEUTRO PERO CERCANO A NEGATIVO^^ "5" significa ESTADO EMOCIONAL TOTALMENTE NEUTRO^^ "6" significa ESTADO EMOCIONAL NEUTRO PERO CERCANO A POSITIVO^^ "7" significa ESTADO EMOCIONAL POCO POSITIVO^^ "8" significa ESTADO EMOCIONAL MODERADAMENTE POSITIVO^^ "9" significa ESTADO EMOCIONAL MUY POSITIVO^^^^ Avanza tan rÃ¡pido como puedas respondiendo con la primer impresiÃ³n que te genere. Avanzar muy lento o pensar demasiado tu respuesta generarÃ¡ resultados difÃciles de interpretar.^^ </page> <data> / file = "experimentoPiloto.iqdat" / columns = [build, date, time, subject, group, blockcode, blocknum, trialcode, trialnum,stimulusitem, latency, response] / separatefiles = true </data> Thanks.

If you need to display several likert-like questions simultaneously, you cannot use <likert> trials. You need to set up <surveypage>s containing e.g. two <radiobuttons> elements instead. A <surveypage> is a special type of <trial>, so you can run them via a <block> just like an other <trial>-type element (<trial>, <likert>, <openended>). > I need to show these images in random order, being sure that more than two images of the same emotional state will never be > displayed consecutively. Set up three <trial>-type elements (see above), one for each emotional category. You might have something like <surveypage positive> ... </surveypage> to display the 5 "positive" images, and <surveypage neutral> ... </surveypage> <surveypage negative> ... </surveypage> for the neutral and negative stimuli respectively. Then set up a <list> imposing the selection constraint (no more than two in a row) via /maxrunsize: <list triallist> / items = (surveypage.positive, surveypage.neutral, surveypage.negative) / poolsize = 15 / maxrunsize = 2 </list> Use that list for trial-selection in your <block>: <block MSDFE> / trials = [1-15 = list.triallist] ... </block>
