increase precision of contrast_samples

[dorcatty]

Dear jsQuestPlus auther,

I have one simple question about how to increase input precision, i went through all demos, it seems the majority sample codes were using:
const contrast_samples = jsQuestPlus.linspace(-40, 0) // [-40, -39, -38, ..., -1, 0]
which generates an array of input value from -400, step 1.
and only one code using double precision like :
const contrast_samples = jsQuestPlus.linspace(0, 1, 100)
which generates an arry of input value from 01, step 1/100

my question is how to generate a input range of 0~1, step 1/1000
i tried with jsQuestPlus.linspace(0, 1, 1000)
but this will slowdown significantly the implementation of code, my browser goes into BUSY forever.

is there any solution to generate more precise input values ? thanks

Thank you for trying to use jsQuestPlus.

Have you already checked this wiki page?

An input range of 0~1, step 1/1000 seems to be too fine. I think this setting imposes a lot of trials on the participants. I recommend measuring at a much coarser stimulus intensity.

Best regards,
