For each question, the TextStim is on the left and the Slider is on the right. I’m using TextStim and Slider components to show survey questions with an appearance similar to the Form component, since this component does not work in Pavlovia. > win.flip() #shows 'some_text' in one line in. I’m using PsychoPy v3.2.4 and writing a Builder program to run on Pavlovia. > win.flip() #shows 'some text' over one line in. > win.flip() #Shows 'Some text' over two lines in. If I add the underscore it fits on the screen but I replace the _ with a space and it goes back to two lines. I'd like to display some text across one line at a large size but it always spreads it out over two lines. In my experiment I am using multiple words, presented as hundreds of letters (equivalent to large nletters in the above example), and thus memory usage (so far I have watched it only via task manager) grows very rapidly, becoming an issue itself.Is it possible to control the width of a bounding box for a text stim? I know the parameter is read only but it adjusts to changes in the size of the text or the length of a word. (which was suggested to circumvent memory problem) does not make opacity change become visible.

There are quite a few parameters that you can play with but minimally, you need to pass the window the text should be displayed in (our win variable) and the actual text you. You can use setColor if you want to set color and colorSpace in one line. First, you need to create the pressescapetext object (instance of the TextStim ) before the main loop. lor + 1, 1, 1 increment all guns by 1 value lor -1 multiply the color by -1 (which in this space inverts the contrast) lor 0.5, 0, 1 decrease red, remove green, keep blue. I'm sure that won't show the same memory problems if you're able to use that. That's written entirely from the ground up (by Sol Simpson) and is more efficient in many ways but doesn't support fonts very well (specifically, only supports mono-spaced fonts at the moment). I know that this issue has been reported before via mailing list (for earlier psychoPy versions), but using setText() after every opacity change is inconvenient because of the recent memory issues ( #973 and related). For this we will use visual.TextStim class from PsychoPy library. PsychoPy also has a stimulus class called TextBox. When programming PsychoPy, it is often the case that a certain sequence of operations, is put together, forming a little. We can do that using psychopys TextStim data type. # won't work without the line below #tText(myTextStim.text) myTextStim. Be able to use psychopy to open a window and draw text to the screen. # present letters one after another for l in letters: # let the opacity values change linearly from 0 to 1 to 0 n = np. # generate some random letters nletters = 10 randomAscii = np. TextStim( win, font = 'Times New Roman', height = 64, color = 'Black') If I want to go larger, which I do, I have to start using the rather unsightly STROKE type fonts which can go a lot larger but do not look nice. draw() slower because that sets the text again. In general, it’s the attributes that affect the shapes of the letters: text, height, font, bold etc. it takes longer to change some attributes. DotStim to show and control movement of dots. I am trying to use PsychoPy to display text (in a decent font - eg, new times roman) but at a size larger than 24 (which seems to be the maximum that GLUT supports). Performance OBS: in general, TextStim is slower than many other visual stimuli, i.e.

Multiple stimuli: ElementArrayStim to show many stimuli of the same type. RadialStim to show annulus, a rotating wedge, a checkerboard etc. SimpleImageStim to show images without bells and whistles. Window( size =( 640, 480), fullscr = False, allowGUI = True, units = 'pix') Images and patterns: ImageStim to show images. During the 8 second exposure to the foreign word, participants are instructed to type in a guess as to what the translation might be.

Basically, a foreign word appears on the screen for 8 seconds, followed by 5 seconds of a translation of that word. From psychopy import core, visual, parallel import numpy as np win = visual. I am using psychopy and python to program a simple psychology experiment.
