Hi all,
I have tried to select different images of an iceberg using the ontrialend-option.
However, it seems like something's going wrong with linking the images: they don't change according to the choices.
Can anyone find the problem in my code?
Participants start trial the first trial with a medium-sized iceberg (picture ib.5/ item 6).
<block B1_products_fb1>
/ trials = [1-5 = noreplace(sus_left_fb1, sus_right_fb1)]
</block>
<trial sus_left_fb1>
/ stimulustimes = [1 = iceberg_animation]
/ correctresponse = ("a")
/ validresponse = ("a", "l")
/ ontrialend = [
IF (trial.sus_left_fb1 == "a") values.iceberg +1;
IF (trial.sus_left_fb1 == "l") values.iceberg -1
]
</trial>
<trial sus_right_fb1>
/ stimulustimes = [1 = iceberg_animation]
/ correctresponse = ("a")
/ validresponse = ("a", "l")
/ ontrialend = [
IF (trial.sus_right_fb1 == "l") values.iceberg +1;
IF (trial.sus_right_fb1 == "a") values.iceberg -1
]
</trial>
<values>
/ iceberg = 6
</values>
<picture iceberg_animation>
/ items = iceberg_picture
/ position = (50, 50)
/ size = (25%, 25%)
/ select = values.iceberg
</picture>
<list iceberg>
/ items = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11)
/ replace = false
</list>
<item iceberg_picture>
/1 = "ib0.png"
/2 = "ib1.png"
/3 = "ib2.png"
/4 = "ib3.png"
/5 = "ib4.png"
/6 = "ib5.png"
/7 = "ib6.png"
/8 = "ib7.png"
/9 = "ib8.png"
/10 = "ib9.png"
/11 = "ib10.png"
</item>
Thanks in advance!
