Staircase handler stepSizes parameter - what are the possibilities?

Coding
10

I’m not sure the solutions presented above actually work, I am getting the same issues as here: Dynamically changing step sizes in a staircase method

from psychopy import data, event
import random
staircase = data.StairHandler(startVal=50, stepType='lin', stepSizes = 10, nUp=1, nDown=2, nTrials=10)

trial = 0
for thisTrial in staircase:
    if trial > 2:
        staircase.stepSizes = 1
    print(thisTrial)
    if random.random() > 0.5:
        staircase.addData(1)
    else:
        staircase.addData(0)
    trial +=1

although interestingly, calling print(staircase.stepSizes) indicates the value is being changed, although as the person replying in the post linked above states, the knock-on effects of initialising with this value don’t carry over.

If anyone does have a solution, I’d love to hear it! for now I may have to hard code in my own staircase :weary:

Edit: found some sort of solution here: stairHandler step size change based on trial number/ dynamic step sizes
