For example, you could use np.hanning(3) or np.random.poisson(10, 10) in a code component. “incorrect” – the text/images for an incorrect response. Many math-related features are available through the complete numpy libraries, which are available within psychopy builder scripts as ‘np.’.“correct” – the text/images you’d like the participant to see after a correct response from psychopy import visual, core window visual.Window( 400,400) fixation visual.TextStim(window, text' ') Draw the stimulus fixation.draw() Refresh/update the window (with the fixation point drawn on) window.flip() core.wait(2.0) message visual.TextStim(window, text'Stimulus') Draw the stimulus message.draw() window.“blockSelect” – leave this one blank for now.Next we’ll add three routines directly after the “Task” Routine. Now, add a keyboard response component, changing the start time to 0.25 (or whichever you’d prefer), “Allowed Keys” to ‘f’, ‘j’ (note the quotes), checking “Store correct”, and changing “Correct answer” to $correctAns. Click the advanced tab and change “Fill Color” to $colorVar and choose “set every repeat”. In the Task routine, create a Polygon component starting at 0 and with an endless duration. Then, create the “Task” routine which will cover the presentation and participant responses. We’d also like to give immediate feedback about whether or not they were correct.įirst, let’s construct a normal instructions routine as in previous examples. To learn how this works, let’s imagine that we’d like our participants to see a red or blue square and then press either ‘F’ for red and ‘J’ for blue. While PsychoPy doesn’t offer direct support for this feature, we can hack conditional branching with a method presented by Mike Wall on his blog. With open('Participant Scores.csv', 'a ') as file:įile.Often times in a psycholinguistic experiment you’ll want to give real time feedback on a participant’s answers. You can use 'while True' and then end the loop using break. ("N:\Task Development\Stimuli/scream.wav").play() counter 1: while counter < 4: print 'still true on iteration number', counter: counter 1: if counter > 2: break break stops the loop.Scores = font_small.render(str(SCORE), True, BLACK)Ĭscores = font_small.render(str(COLLISION_SCORE2), True, BLACK)ĭISPLAYSURF.blit(cscores, (SCREEN_WIDTH-60, 10))ĭISPLAYSURF.blit(entity.image, entity.rect) #("D:\Pygame Project\Stimuli/spawn.wav").play() Self.image = ("N:\Task Development\Stimuli/greendot.png") (screen, RED, )įont = ("Verdana", 40)įont_small = ("Verdana", 20)īackground = ("N:\Task Development\Stimuli/trial.jpeg")ĭISPLAYSURF = _mode((SCREEN_WIDTH, SCREEN_HEIGHT), pygame.RESIZABLE) # Loop until the user clicks the close button. #CALIBRATION_SPEED = (input('Enter multiplier value')) SCREEN_WIDTH, SCREEN_HEIGHT = ().current_w, ().current_h Here is the entire, albeit lengthy, code: import pygame, sys If anyone could help me adjust the code so that it can be integrated into the loop 20 times in PsychoPy please, I would be most appreciative! Currently, after the 5 seconds, the screen remains blank white and won’t load into the next routine. I have attached an image of the desired routine/loop for reference.Ĭurrently, as it is, the task exits through pygame.quit() and win.flip(), but both of these exit the entire task, rather than exiting back to the loop. The same task would be repeated 20 times, forming one overall larger trial. Psychopy get loop number series#I’d like it to be as a five-second routine in builder and then repeat as a series of trials. I have a code component which saves each response as a separate audio file: vpvk vk. I’m building an experiment in which participants (verbally) name pictures presented onscreen, and their responses are detected by a nearby microphone. I have my task coded in Python, which I’ve integrated into PsychoPy using builder. Specifying trial/loop number within a code component.
