And keep those pictures coming back in the trials within one block. So there are two requirements 1) the first picture can not be the same as the second picture and 2), pictures need to remain the same throughout the trials in this specific block. Any advice? thx!! <trial polygonaction> /stimulustimes = [1=polygonaction] /timeout = 1000 </trial> <trial polygoninaction> /stimulustimes = [1=polygoninaction] /timeout = 1000 </trial> <picture polygonaction> /items = polygons </picture> <picture polygoninaction> /items = polygons </picture> <item polygons> /1 = "1.jpg" /2 = "2.jpg" /3 = "3.jpg" /4 = "4.jpg" /5 = "5.jpg" /6 = "6.jpg" /7 = "7.jpg" /8 = "8.jpg" /9 = "9.jpg" /10 = "10.jpg" /11 = "11.jpg" /12 = "12.jpg" /13 = "13.jpg" /14 = "14.jpg" </item>
