Hi Emma, I've just answered your other post. If the contents of two posts are fairly similar, try to stick to just a single post in the future! ;) I suggest you do the cats dogs & capybara's tutorial, as it employs both visual and auditory stim…

Hi Emma, welcome to the forum! To start off with your second question, when you collect a mouse response (with the mouse response item), it logs the button but also the X and Y-coordinates. You can use these coordinates to provide participants posi…

Hi Arpit, It could be that your eyetracker is set to 'dummy mode' in the pygaze_init item. The drift correction only works if you've selected the correct eye tracker in this item. Of course this means you also have to have this item somewhere in yo…

Hi Rampriya, Similar questions have been asked throughout the years, see for instance http://forum.cogsci.nl/index.php?p=/discussion/23/solved-go-nogo-task Cheers Josh

Hi Vatsal, The loop table shows you which conditions (factor combinations) will appear in your experiment. You can alter the cells as you please, so getting 36 valid cue trials and 10 of each other type really comes down to just making the cue colu…

Hi Veronica, When looking at the logfile, does the response variable actually show values beyond 10000? Cheers Josh
-
Hi Veronica, You're giving the feedback item two textlines, and I think the second one overrules the first one. So you're only left with a "you answered on time", which is presented when the response time is under 10000. What you need to …

Hi Natalie, It would be helpful to know not only what you did, but also how you did it. Did you prepare your sketchpad similar to how it is done in the tutorials? (see for instance the Cats Dogs & Capybara's tutorial) Cheers Josh

Hi, What have you got so far? Would it be something for which you could use a multiple-choice form item, or are you for instance using images on which participants should click? A bit more detail would be helpful here. Cheers, Josh

Hi Stephan, Some keyboards / computers can only process two keypresses at once - or at least purposefully limit the amount of keypresses coming from the same region, cause it would then be likely that you mispressed one key or the other. See this f…

Hi, You say you've created a self-paced reading task. Where do reaction times and accuracies come from then? Are the sentences followed by questions? Cheers, Josh
-
Hi! 1) Yes, deleting the undesired rows will be sufficient (be sure to move the rest up and set the correct number of cycles though). 2) Well, there are multiple ways of doing things. If you have a correct_response variable in your loop item, then…

Hi Sylvia, The form_text_input item allows you to provide a sentence to participants and ask them to give the missing word as text input. Of course if you prefer to present the sentence to participant before presenting the text input screen you cou…

Hi Raquel, Could it be that your practice trials are included in the equation? In any case, you also have the variable correct, which will always be a long column of 1's and 0's in your .csv file. You can calculate the accuracy based on that as we…

Hi, I've just answered this question in your previous post. Cheers
-
Hi, I've checked, and you need to enter None as the correct response, not 'none' like I said earlier. Sorry about that! In the allowed response box, you could enter None;s (in case the desired allowed keypresses would be 's' and no keypress). One ad…
-
Alright! In this case it would be good to have a variable like target_same in your loop item, with two possible values, yes and no. You can insert two target sketchpads in your sequence, one of which would be displayed if target_same is yes, and th…
-
Hi Nick, I can't reproduce your problem, but what you could do in any case, is to create a folder called _ _ pool _ _ (without spaces), in the same directory as your experiment file. Placing all your desired files in this folder is the same as drag…
-
Hi Charizard, It would be best to place your practice block in a loop item (and this loop item you just set to 99 cycles or something). Ticking the "show advanced options" box, you'll reveal a break-if statement that is set to never by de…
-
Hi, It depends on whether the distance between the first and the final target is something you want to be random, or rather fixed (like 4 different values for N). In case of the latter, N should be one of the experimental variables declared in your…

Hi Aurelia, Based on this information I can't be sure yet what causes your problem. If I understand correctly, the trial runs fine most of the time? Cheers Josh
-
Hi Ellie, not sure, maybe your image is too large by default? Did you try rescalign and repositioning the image? Cheers Josh
-
Hi Craig, I think this will require the use of inline_scripts. You could create two lists, say, high_matching and low_matching, that have a number of items equal to your desired number of trials. As items, you could have a bunch of 1's and 0's to i…
-
Greetings, The way you initiated your keyboard, it will only recognize shift presses because these are the only things that are in your keylist. Still, there is the problem of the get_key() command only taking in one key at a time. Possibly, you c…
-
Hi Arturo, It would be best to place an inline_script right after your keyboard response with response_moment = self.time()-start_time in the run-phase. At the start of your experiment you place another inline_script with start_time=self.time() in…
-
Hi Vatsal, So the experiment displays the cue screen correctly, but doesn't follow up with a target screen? Have you tried displaying the target screen outside the trial loop? The problem may also be caused due to the logic of your code. Can you sh…

Hi Laura, you might want to use form_text_input instead of the base form! Cheers, Josh

@sebastiaan Woops, my bad..!

Hi Abby, It looks like you're thinking of a Latin-squared design where participants have to be divided into two groups, one where the first six words are shown unspaced and the second six words spaced, and another group where the first six words ar…

Hi, What you describe here, is basically covered by the drift correction item alone. In the drift correction, participants focus on a centrally positioned dot and have to press the spacebar. The system then aligns the eye position coordinates at th…
