Here's an extended example for you to work from (you need to change some of the <text> elements to <picture> elements, but otherwise it all works the same). The number of items is reduced to four sentences (1 to 4) and two individuals (A and B) for clarity / illustrative purposes. It can easily be extended to more (e.g. the full 24 sentences / 8 individuals set):
<expt>
/ blocks = [1=presentationblock; 2=recallblock]
</expt>
<block presentationblock>
/ trials = [1-4=presentationtrial]
</block>
<block recallblock>
/ trials = [1-4=recalltrial]
</block>
*Display random sentence / photo pairing*
*Store pairing in item elements for retrieval during recall*
<trial presentationtrial>
/ ontrialend = [item.sentencerecallitems.item=text.sentence.currentitem;
item.photorecallitems.item=text.photo.currentitem; ]
/ stimulusframes = [1=sentence, photo]
/ validresponse = (noresponse)
/ trialduration = 4000
</trial>
*Show random sentence for recall*
*Retrieve associated photo from item element for response evaluation*
<trial recalltrial>
/ stimulusframes = [1=sentencerecall, photoa.jpg, photob.jpg]
/ inputdevice = mouse
/ validresponse = (photoa.jpg, photob.jpg)
/ iscorrectresponse = [trial.recalltrial.response==item.photorecallitems.item(text.sentencerecall.currentindex)]
</trial>
<text sentence>
/ items = sentenceitems
/ position = (50%, 75%)
</text>
<text sentencerecall>
/ items = sentencerecallitems
/ position = (50%, 75%)
</text>
<text photo>
/ items = photoitems
/ position = (50%,50%)
</text>
<text photoa.jpg>
/ items = ("PhotoA.jpg")
/ position = (25%,50%)
</text>
<text photob.jpg>
/ items = ("PhotoB.jpg")
/ position = (75%,50%)
</text>
<item sentenceitems>
/ 1 = "Sentence 1"
/ 2 = "Sentence 2"
/ 3 = "Sentence 3"
/ 4 = "Sentence 4"
</item>
<item photoitems>
/ 1 = "PhotoA.jpg"
/ 2 = "PhotoA.jpg"
/ 3 = "PhotoB.jpg"
/ 4 = "PhotoB.jpg"
</item>
<item sentencerecallitems>
</item>
<item photorecallitems>
</item>
Hope this helps.
