+x+x+x+x+x+x+x+x+x+xHi, Quick question. I need a participant to click 3 times on a certain image within a trial (Image A). Once this happens another image on the screen should then change from one state to another (Image B should change). Is this possible to achieve with Inquisit 4 at all? Any help would be very appreciated. Thanks, Sean Yes, this is certainly possible. However, your description is a bit too vague to give a concrete example. The easiest way would be to simply run a <trial> that collects a single click on image A three times in a row, and then follow that up with another, different <trial> that displays the changed image B. Thanks Dave for the speedy reply. Below you can find the code I've tried to implement to solve my problem. To quickly summarize, I would like participants to press "button 3" multiple times. Once this happens the Purple card should turn yellow. I can do this for a single trial (by using the correctstreak option). But my problem is that I need to present the first trial 30 times per block. So I need to reset the correctstreak variable each time the participant returns to the first trial. At the moment I don't know how to achieve this... <trial Card_Presentation_Blue_Purple_Green> / inputdevice = mouse / correctresponse = (button_3) / validresponse = (Blue_Card_Left, Purple_Card_Center, Green_Card_Right, button_3) / stimulustimes = [0 = total_points, Stage, button_1, button_2, button_3, Blue_Card_Left, Purple_Card_Center, Green_Card_Right] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.correctstreak < 3) trial.Card_Presentation_Blue_Purple_Green] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.correctstreak > 2) trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Blue_Card_Left") trial.Feedback_Avoid_Spiders_Blue_Card_Presentation_Blue_Purple_Yellow] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Purple_Card_Center") trial.Feedback_Loss_Points_Purple_Card_Presentation_Blue_Purple_Yellow] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Green_Card_Right") trial.Feedback_Loss_Points_Green_Card_Presentation_Blue_Purple_Green] </trial> <trial Card_Presentation_Blue_Purple_Yellow_Follow_Rule> / inputdevice = mouse / correctresponse = (Yellow_Card_Right) / validresponse = (Blue_Card_Left, Purple_Card_Center, Yellow_Card_Right) / stimulustimes = [0 = total_points, Stage, button_1, button_2, button_3, Blue_Card_Left, Purple_Card_Center, Yellow_Card_Right] / branch = [if (trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule.response == "Blue_Card_Left") trial.Feedback_Avoid_Spiders_Blue_Card_Presentation_Blue_Purple_Yellow] / branch = [if (trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule.response == "Purple_Card_Center") trial.Feedback_Loss_Points_Purple_Card_Presentation_Blue_Purple_Yellow] / branch = [if (trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule.response == "Yellow_Card_Right") trial.Feedback_Spider_Money_Yellow_Card_Presentation_Blue_Purple_Yellow] </trial> Note if there is a better way to solve my issue I'm all ears! Best, Sean You shouldn't use correctstreak here. Set up a global variable (<values> entry) to count the clicks. /branch when the variable equals 3. Reset the variable back to 0 at the end of the "round" in <trial Card_Presentation_Blue_Purple_Yellow_Follow_Rule. I.e. <values> / clickcount = 0 </values> <trial Card_Presentation_Blue_Purple_Green> ... / ontrialend = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Yellow_Card_Right) values.clickcount += 1] ... / branch = [if (values.clickcount> 2) trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule] ... </trial> <trial Card_Presentation_Blue_Purple_Yellow_Follow_Rule> ... / ontrialend = [values.clickcount = 0] ... </trial> Hope this helps. Works like a charm! Many thanks Dave. One last question: I want each block to be comprised of 15 trials. However, when using the above solution, I now only get five trials per block. This is because when I click on Image A three times the script increments the total trial count every time (i.e., each click counts as a trial). Is there any way of subtracting 3 from the total trial count at the end of trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule (i.e., after the participant clicks three times on the image)? > I want each block to be comprised of 15 trials. However, when using the above solution, I now only get five trials per block. I don't know how you've set up the respective <block>(s) (the code snippets you posted do not include any <block> elements), so I'm not sure how to answer that. I'd need more info here. > Is there any way of subtracting 3 from the total trial count Here too, I'm not entirely sure what you are referring to with "total trial count". A built-in property? How / where do you use that property? Also, why not triple the amount of trials instead (i.e., 3 x 15 = 45)? Thanks. Apologies - below you can find a code snippet for both trial and block: <trial Card_Presentation_Blue_Purple_Green> / inputdevice = mouse / correctresponse = (button_3) / validresponse = (Blue_Card_Left, Purple_Card_Center, Green_Card_Right, button_1, button_2, button_3) / stimulustimes = [0 = total_points, Stage, button_1, button_2, button_3, Blue_Card_Left, Purple_Card_Center, Green_Card_Right] / ontrialend = [if (trial.Card_Presentation_Blue_Purple_Green.response == "button_3") values.click_count += 1] / branch = [if (values.click_count > 2) trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Button_1") trial.Card_Presentation_Blue_Purple_Green] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Button_2") trial.Card_Presentation_Blue_Purple_Green] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Blue_Card_Left") trial.Feedback_Avoid_Spiders_Blue_Card_Presentation_Blue_Purple_Green] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Purple_Card_Center") trial.Feedback_Loss_Points_Purple_Card_Presentation_Blue_Purple_Green] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Green_Card_Right") trial.Feedback_Loss_Points_Green_Card_Presentation_Blue_Purple_Green] </trial> <trial Card_Presentation_Blue_Purple_Yellow_Follow_Rule> / inputdevice = mouse / correctresponse = (Yellow_Card_Right) / validresponse = (Blue_Card_Left, Purple_Card_Center, Yellow_Card_Right) / stimulustimes = [0 = total_points, Stage, button_1, button_2, button_3, Blue_Card_Left, Purple_Card_Center, Yellow_Card_Right] / ontrialend = [values.click_count = 0] / branch = [if (trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule.response == "Blue_Card_Left") trial.Feedback_Avoid_Spiders_Blue_Card_Presentation_Blue_Purple_Yellow] / branch = [if (trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule.response == "Purple_Card_Center") trial.Feedback_Loss_Points_Purple_Card_Presentation_Blue_Purple_Yellow] / branch = [if (trial.Card_Presentation_Blue_Purple_Yellow_Follow_Rule.response == "Yellow_Card_Right") trial.Feedback_Spider_Money_Yellow_Card_Presentation_Blue_Purple_Yellow] </trial> and Block: <block Training_Block_1> / screencolor = white / trials = [1-15 = noreplacenorepeat(Card_Presentation_Blue_Purple_Green)] </block> In explaining my problem I originally over simplified. Basically there are three buttons that participants can push (A,B,C). There are three playing cards participants can also choose (Blue, Purple, Green). If participants press a certain button three times (Button C) then one of the cards (Green) changes color (Yellow). Now if participants choose a Green, Blue, or Purple playing card the trial number increments by +1 (i.e., this is working fine). However, if participants do what I want them to do (i.e., press Button C three times then click on the Yellow card) then the script counts this as four trials. So what I want is this: if people click three times on Button C then choose the Yellow Card the script counts this as "one trial". This way participants can repeat this same behavior 15 times. In short, I need a way to have my Inquisit script either (a) treat three presses on Button C followed by a Yellow Card selection as a single trial (and thus do this 15 times) or (b) count this as four trials (i.e., three button presses and a card selection = 4 trials) and then subtract 3 from the total trial count after a Yellow Card selection so that it only *technically* counts as a "single trial". I hope this is clear. If not, just let me know. Best, Sean > Now if participants choose a Green, Blue, or Purple playing card the trial number increments by +1 Which trial number? I don't see any trial number used anywhere in the script snippet. Also, I think there's a misunderstanding. <block Training_Block_1> ... / trials = [1-15 = noreplacenorepeat(Card_Presentation_Blue_Purple_Green)]... </block> instructs the block to run 15 instances of <trial Card_Presentation_Blue_Purple_Green> via the /trials attribute. Any instances you invoke via /branch as in <trial Card_Presentation_Blue_Purple_Green> ... / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Button_1" ) trial.Card_Presentation_Blue_Purple_Green] / branch = [if (trial.Card_Presentation_Blue_Purple_Green.response == "Button_2") trial.Card_Presentation_Blue_Purple_Green] ... <trial> are *in addition* to that. One more thing: I'm not clear on how you actually want to use values.clickcount. Suppose the participant clicks button_3 twice, i.e. values.clickcount is increased to 2, and then the participant clicks button_2. What is supposed to happen with values.clickcount? Is it to remain at the value 2 or is it supposed to go back to 0? If the latter, that logic is missing currently. Perhaps a simple example will help: This runs 10 rounds. A round advances to the next once three consecutive clicks on the object A have occurred. <values> / round = 0 / a_consecutiveclickcount = 0 </values> <block example> / trials = [1-10 = startround] </block> <trial startround> / ontrialbegin = [values.round += 1; values.a_consecutiveclickcount = 0; text.a.textbgcolor = grey;] / branch = [trial.a_or_b] / trialduration = 0 </trial> <trial a_or_b> / stimulusframes = [1=a,b,debug] / validresponse = (a,b) / inputdevice = mouse / ontrialend = [if (trial.a_or_b.response == "a") values.a_consecutiveclickcount += 1] / ontrialend = [if (trial.a_or_b.response != "a") values.a_consecutiveclickcount = 0] / branch = [if (values.a_consecutiveclickcount > 2) trial.a_change else trial.a_or_b] </trial> <trial a_change> / ontrialbegin = [text.a.textbgcolor = green;] / stimulusframes = [1=a,b,debug] / inputdevice = mouse / validresponse = (a) </trial> <text a> / items = ("A") / erase = false / position = (40%, 50%) / size = (10%, 10%) / vjustify = center / txbgcolor = grey </text> <text B> / items = ("B") / erase = false / position = (60%, 50%) / size = (10%, 10%) / vjustify = center / txbgcolor = grey </text> <text debug> / items = ("Round #<%values.round%> | Consecutive clicks on A: <%values.a_consecutiveclickcount%>") / erase = false / size = (60%, 10%) / position = (50%, 10%) </text> Perfect - thanks for the advice. I finally got it working! Best, Sean
