help--alternating text and image stimuli

[Rick O'Gorman]

As per an earlier post, sorry to have lagged in my reply to this thread. 
Thanks to those who suggested ideas--David McF, Paul J, liwenna. On 
seeing Paul's suggestion, using a substantial bit of inline code, I was 
inspired to try figuring out the slidestate method, as it seemed simpler. :)

David's email confirmed what I had found--that Slidestate was the 
solution, but I did not need to use inline code to tell E-Prime which 
slidestate to use. It's simpler than that.

After setting up the alternative slidestates and naming them (you get at 
this by right-clicking on the tab at the bottom, which will default to, 
err, 'default', then 'default1', etc.), you can tell E-Prime which one 
to use in the Slide's general property options. Under the General tab, 
there's a setting for Activestate. Instead of choosing one of the 
slidestates that you have created, you can instead enter a variable name 
in here (e.g., [stimtype]) and then set up which slidestate to use in a 
list elsewhere, using one of the slidestate names (in my case, I had 
two, one called 'text' and one called 'pic'). So in my relevant list, I 
had a variable called slidestate that took either a value of 'pic' or 
'text' depending on another variable setting (whether I wanted to 
present an image or text as a stimulus). This then told the relevant 
slide to use either pic or text, as appropriate.

By the way, when creating multiple slidestates that are variations of 
each other, there is a 'clone state' option, which is a nice 
labour-saving tool.

Maybe E-Prime will keep me loyal yet. :)
