You'd basically have a video or (even better) a flash file that serves as a digital clock.


A flash file! I hadn't thought of this before. Great idea.

The second question is a bit of the same: is it possible to make a timer without implementing every possible time?


With a little bit of lateral thinking, yes. I've used the <video> element and the <block> element's '/bgstim' command in the past to provide participants with continuous information about the elapsed time across trials. You'd basically have a video or (even better) a flash file that serves as a digital clock. I can email you these files as well as an example script if you want.

I didn't thought about that possibility! It certainly is a more hansome solution in the script. I would really appreciate it if you would sent the files. I'm curious how that will look. Too bad my employer doesn't really care much for the way it is implemented, just how it looks :)
My mailadress is nospam_i.grisel@student.ru.nl (without the nospam_ obviously). Thanks!

Hey Sean,

Of course it is possible to put the script online. You can find it at www.student.ru.nl/i.grisel/Subconcious Experiment.zip .

A little explanation on the files: I've stripped both files to the bare/bear essentials. This includes two main parts, namely presenting cars and getting a nice timer. Since both took a lot of stimuli to make, I've made three files. The first one is to run the whole experiment, namely Subconcious Experiment.exp. The stimuli file is named Random Car Stimuli.exp. Next to that I've also have a file with the car specifications which is in Auto.exp.
A little bit more explanation is required for the Stimuli file. Since I had three variables which needed to be created random for each participant, that gave me a lot of combinations for cars (10 possible carnumbers, 10 possible colors and 10 possible sets of specifications). To get the random lists, I made 3 item-lists, got to present this list randomly (shown in white and timeout 0)(via a trial and block) and let it put the presented words back in a list.
After that, I hard-scripted every possible combination so I could activate them with a branch command. Don't worry, I didn't type it all: I let my little Python script do it for me ;) So my question about this is, if there's a way to do it in a more flexible way, in which Inquisit generates the random lists and maybe even reduce the hard-scripting?
The second question is a bit of the same: is it possible to make a timer without implementing every possible time?

Thanks a lot for your help!

Ivor

Hi Ivor,


Would it be possible to attach your script to this message thread? That would allow me to see more clearly what you are trying to do and determine whether there is a more efficient way.


Thanks,
Sean

Hey everyone,

Currently I'm making a unconcious thinking task. For this, people get presented a lot of information, in this case the specifications of cars. The idea of presenting this information is that it is random for every participant. There are 3 variables, which have to be randomly selected, but are connected to each other and can't change during the entire experiment: the number of the car, the color of the car and the set of 10 specifications. I've been able to randomize these variables, but I did it via a detour (let a combination of a trial and block take random items from a item-list and then put them in another item-list). Is there a more easier way for me to do this? The possible parameters are quite easy: the carnumbers and the set numbers range from 1 to 10. The colors are: dark blue, light blue, dark green, light green, orange, pink, yellow, red, black and grey.

Kinds regards,

Ivor
