Hi!
I am doing a picture-based IAT and I keep getting the error message: /items: Unable to load the picture "C:\Users\Desktop\stimuli_neutral & stimuli_negative" Verify that the file exists and is of a supported format.

The file with the target pictures is saved on my desktop (in the same file as the experiment I am doing) and all pictures are in jepg format

atm this part of my experiment looks like this:

<item stimuli_neutral>
/1 = "sb1_MNES_5_0.jpg"
/2 = "sb1_MNES_5_1.jpg"
/3 = "sb1_MNES_5_2.jpg"
/4 = "sb1_MNES_5_3.jpg"
/5 ="sb1_MNES_5_4.jpg"
/6 = "sb1_MNES_5_5.jpg"
/7 ="sb1_MNES_5_6.jpg"
/8 ="sb1_MNES_5_7.jpg"
/9 ="sb1_MNES_5_8.jpg"
/10 ="sb1_MNES_5_9.jpg"
</item>

<item stimuli_negative>
/1 = "sb1_MNES_5_0_neg.jpg"
/2 = "sb1_MNES_5_1_neg.jpg"
/3 = "sb1_MNES_5_2_neg.jpg"
/4 = "sb1_MNES_5_3_neg.jpg"
/5 = "sb1_MNES_5_4_neg.jpg"
/6 = "sb1_MNES_5_5_neg.jpg"
/7 = "sb1_MNES_5_6_neg.jpg"
/8 = "sb1_MNES_5_7_neg.jpg"
/9 = "sb1_MNES_5_8_neg.jpg"
/10 = "sb1_MNES_5_9_neg.jpg"
</item>

<picture paradigm>
/items = ("stimuli_neutral & stimuli_negative")
/position = (50, 50)
</picture>


If anyone could help me out that'd be so great!!

That's simply not valid Inquisit syntax. If you want to refer to an <item> element, you ought to do

/items = nameofitemelement

and you cannot refer to multiple <item> elements as it appears you are trying to do. I recommend you work through the picture IAT tutorial included in the Inquisit documentation for further practical examples.
