How to delete items from pictures, and to be able to use remaining ones in another trial?

mingwu — Mon, 07 Nov 2016 06:59:03 GMT

My task is to run the trials where I show some pictures(not all) from summerpicture, and once I have finished to show them, I would like to have 2 collections of: 1.pictures that were displayed and 2. pictures that were not displayed!!. I need to show non-displayed pictures separately for my second trial.

Here is my thinking:

I think my problem occurs in ontrialend.

Actually, my first trial(summerdelete) does not show any errors

/ontrialbegin = [

values.congruency = 1;

]

/ stimulustimes = [1=summerpicture]

/ correctresponse = ("d")

/ validresponse = ("d", "f", "j", "k")

/ontrialend = [

item.summerremained.removeitem(picture.summerpicture.currentindex);

item.summerdisplayed.appenditem(picture.summerpicture.currentitem);

]

</trial>

However, when I run the second one,

/ontrialbegin = [

values.congruency = 1;

]

/ stimulustimes = [1=summerpicturerest]

/ correctresponse = ("d")

/ validresponse = ("d", "f", "j", "k")

/ontrialend = [

list.latencies.insertitem(trial.purpleincongruent.latency, 1);

I get an error, for example

Unable to initialize <picture summerpicturerest> item number 8. Verify the item exists and is correctly defined.

Please, help. I think the way I am deleting items is wrong.

Here is, how I am declaring items and pictures.

/1="Summer/1.jpg"

/2="Summer/2.jpg"

/3="Summer/3.jpg"

/4="Summer/4.jpg"

/5="Summer/5.jpg"

/6="Summer/6.jpg"

/7="Summer/7.jpg"

/8="Summer/8.jpg"

</item>

/1="Summer/1.jpg"

/2="Summer/2.jpg"

/3="Summer/3.jpg"

/4="Summer/4.jpg"

/5="Summer/5.jpg"

/6="Summer/6.jpg"

/7="Summer/7.jpg"

/8="Summer/8.jpg"

</item>

</item>

/ items = summeroriginal

/ valign =center

/ height = 35

/halign=center

/ width = 80

/ size = (60%,60%)

</picture>

/ items = summerremained

/ valign =center

/ height = 35

/halign=center

/ width = 80

/ size = (60%,60%)

</picture>

Instead of removing images from and appending them to <item> elements, the better way is to simply work with *item numbers* and distribute them to various <list>s for selection. See e.g. https://www.millisecond.com/forums/FindPost17070.aspx
