Hi,
I am using the slider element in my Inquisit script to get some participant ratings. I was wondering if there was any way to force the slider itself (i.e. the part you move to indicate your response on the scale) to start in the "0" position? At this point, the survey opens with the slider at the midpoint of the scale. In the example below it is not a HUGE issue, but is is when I have an a 'range' of 1-4, and the slider is automatically positioned at 3 (which could would bias responses).

Is there something simple I am missing to fix this?

<slider Lazy>
/ caption = "Lazy:"
/fontstyle = ("Ariel", 16, true, false, false, false, 5, 0)
/labels = ("Not at all", "Extremely")
/ range = (0, 100)
/ increment = 10
/ slidersize = (50, 5)
/ showtooltips = true
/ required = false
</slider>

<slider Sloppy>
/ caption = "Sloppy:"
/fontstyle = ("Ariel", 16, true, false, false, false, 5, 0)
/labels = ("Not at all", "Extremely")
/ range = (0, 100)
/ increment = 10
/ slidersize = (50, 5)
/ showtooltips = true
/ required = false
</slider>

<slider Motivated>
/ caption = "Motivated:"
/fontstyle = ("Ariel", 16, true, false, false, false, 5, 0)
/labels = ("Not at all", "Extremely")
/ range = (0, 100)
/ increment = 10
/ slidersize = (50, 5)
/ showtooltips = true
/ required = false
</slider>

<slider PPH>
/ caption = "Poor personal hygeine:"
/fontstyle = ("Ariel", 16, true, false, false, false, 5, 0)
/labels = ("Not at all", "Extremely")
/ range = (0, 100)
/ increment = 10
/ slidersize = (50, 5)
/ showtooltips = true
/ required = false
</slider>

<slider OverIndulgent>
/ caption = "Over-indulgent:"
/fontstyle = ("Ariel", 16, true, false, false, false, 5, 0)
/labels = ("Not at all", "Extremely")
/ range = (0, 100)
/ increment = 10
/ slidersize = (50, 5)
/ showtooltips = true
/ required = false
</slider>

<slider SelfDisciplined>
/ caption = "Self-disciplined:"
/fontstyle = ("Ariel", 16, true, false, false, false, 5, 0)
/labels = ("Not at all", "Extremely")
/ range = (0, 100)
/ increment = 10
/ slidersize = (50, 5)
/ showtooltips = true
/ required = false
</slider>

<surveypage NOS>
/caption = "Please indicate the extent to which you the believe each of the following characteristics describes the patient by moving the markers to the appropriate places on the lines below:"
/ fontstyle = ("Ariel", 20, true, false, false, false, 5, 0)
/ questions = [1=Lazy; 2=Sloppy; 3=Motivated; 4=PPH; 5=OverIndulgent; 6=SelfDisciplined]
/ response = free
</surveypage> 

<survey NOSSurvey>
/ pages = [1=NOS]
/ itemspacing = 2%
/ response = anyresponse 
/ recorddata = true
/ showpagenumbers = false
/ showquestionnumbers = false
/ nextbuttonposition = (90,90)
</survey>

I would also like to know if there is a way to present an image for a specific amount of time (e.g., 4 seconds), and then once that time has elapsed, to have some text automatically appear on the same page as the image (this might be to vague for anyone to answer) - I've been looking into it, but have been unsuccessful so far. 

Thank you for any help!

> I was wondering if there was any way to force the slider itself (i.e. the part you move to indicate your response on the scale) to start in the "0" position?

Yes, via the <slider> element's /defaultresponse attribute:

<slider q1>
/ caption="How do you feel about bananas?"
/ defaultresponse = "0"
/ labels=("Cold", "Hot")
/ range = (0, 4)
/ increment = 1
</slider>

> I would also like to know if there is a way to present an image for a specific amount of time (e.g., 4 seconds), and then once that time has elapsed, to have some text automatically appear on the same page as the image

You would do so using the <trial> element's /stimulustimes attribute:

<trial mytrial>
/ stimulustimes = [0=mypicture; 4000=mytext]
...
</trial>

Thanks! That all works fine now. 
With the "/ stimulustimes = [0=mypicture; 4000=mytext]" you suggested though, is there a way to have a "Next" button at the end? For example, I want participants to see an image for only 4 seconds, then the text pops up (which is working), but I want them to be able to read this text for as long as they need, and then move forward when they are ready (rather than having something like an automatic timeout or trialduration which will force them to move on). 

I haven't been able to find a way to do this using this attribute yet.

Yes. Simply set up a simple <text> element to serve as your "Next" button, display it along with the other stimuli and define it as the <trial>'s expected response

<trial mytrial>
/ stimulustimes = [0=mypicture; 4000=mytext, mynextbutton]
/ inputdevice = mouse
/ validresponse = (mynextbutton)
...
</trial>

Perfect. Thank you.

The way the script is now, my blocks (and trials) are not randomised - they are simply presented in the order of the exp1 exp2 etc. Now, I am trying to randomise "targetblock1", "targetblock2" "targetblock3". When I have a go at changing the script myself I can easily get the blocks to randomise, but not without replacement - so the blocks repeat themselves in different orders instead of presenting the 3 of them in random order (e.g., sometimes it might show targetblock1 followed by targetblock3 followed by targetblock1). So far, I have tried to use "resetinterval", but I haven't had any luck. How can I get my script to randomise in the way I want?

Hopefully I have explained myself properly. Let me know if I am not making sense :) 

I've included my whole script if you need to have a look at it (which doesn't include my attempts to randomise):

JRB,

<expt> elements aren't <block>s. You don't randomize <expt> elements. Instead you use an <expt> element's /blocks attribute to randomize the <block>s it runs, as in

<expt>
/ blocks = [1-3=noreplace(blocka, blockb, blockc)]
...
</expt>

or

<expt>
/ blocks = [1,3,5=noreplace(blocka, blockb, blockc); 2,4,6=noreplace(blockd, blocke, blockf)]
...
</expt>

etc.

all of which you will find documented in the language reference for the /blocks attribute.
