Hi all! I’m in desperate need of help, since I am mostly self-taught in coding and I can’t seem to figure out this one. Basically, i am trying to recreate the second experiment of this study: On the nature of the stimulus information necessary for estimating mean size of visual arrays - PMC
I need to create two arrays of circles, each containing 7 circles. Each circle can be either “small” or “large” – the larger ones being 20% bigger in diameter. Each array contains a random selection of “large” and “small” circles. Now, the real problem is that these arrays need to appear as T2 during a RSVP task.
So, this is my code for the RSVP:
from psychopy import visual, core, event
import random
import string
num_stimuli = 20
target_positions = [11, 14]
stimuli = [ ]
for i in range(num_stimuli):
if i in target_positions:
stimulus = str(random.randint(0, 9))
else:
stimulus = random.choice(string.ascii_uppercase)
stimuli.append(stimulus)
text_stim = visual.TextStim(win, text='', color="white")
for stimulus in stimuli:
text_stim.text = stimulus
text_stim.draw()
win.flip()
core.wait(0.10)
but i can’t seem to understand how i should implement the two circles arrays as T2
