Group: Forum Members Posts: 7, Visits: 66	Dear all, For my adjusted cyberball experiment I would like to modify the time interval between the mouse click of the participant and the "response of the ball". For example, the participant clicks on player 1 to throw the ball to player 1 but the gif showing the ball movement will only start 500 ms after the mouse click. Is it possible to do this in Inquisit? Or do I have to modify the gif so that it will just show a picture for the first 500 ms? script for player 3 throwing ball to player 2 (participant) and player 2 to player 1: <trial 3to2> /ontrialbegin = [values.player = 2] / stimulusframes = [1= 3to2, player1label, player2label, player3label, player4label] / validresponse = (text.player1label, text.player3label, text.player4label) / inputdevice = mouse /ontrialend = [if (trial.3to2.response == "player1label") {values.recipient = 1; values.count_player2throws += 1}] /ontrialend = [if (trial.3to2.response == "player3label") {values.recipient = 3; values.count_player2throws += 1}] /ontrialend = [if (trial.3to2.response == "player4label") {values.recipient = 4;values.count_player2throws += 1}] / branch = [if (values.recipient == 1) trial.2to1] / branch = [if (values.recipient == 3) trial.2to3] / branch = [if (values.recipient == 4) trial.2to4] </trial> <trial 2to1> /ontrialbegin = [values.player = 1] / stimulusframes = [1= 2to1, player1label, player2label, player3label, player4label] / validresponse = (noresponse) / inputdevice = mouse /ontrialend = [if (list.player1schedule.nextvalue == 2) {values.recipient = 2; values.count_player1throws += 1}] /ontrialend = [if (list.player1schedule.nextvalue == 3) {values.recipient = 3; values.count_player1throws += 1}] /ontrialend = [if (list.player1schedule.nextvalue == 4) {values.recipient = 4; values.count_player1throws += 1}] / trialduration = expressions.cyberdecisiontime / branch = [if (list.player1schedule.currentvalue == 2) trial.1to2] / branch = [if (list.player1schedule.currentvalue == 3) trial.1to3] / branch = [if (list.player1schedule.currentvalue == 4) trial.1to4] Thank you in advance! Kind regards, Esther

Kind regards, Esther If you add either a 500 ms /pretrialpause or /posttrialpause to the <trial> elements, that should do the trick. <trial 2to1> / pretrialpause = 500 ... </trial> Alternatively, you can change /stimulusframes to /stimulustimes and only display the stimuli starting 500ms into the <trial> / stimulustimes = [500 = 2to1, player1label, player2label, player3label, player4label] and if you want to delay just the video, but not the other stimuli, do / stimulustimes = [0= , player1label, player2label, player3label, player4label; 500 = 2to1]

Thank you for your answer! Using the /pretrialpause seems to work. However, instead of showing nothing during that pause, I'd like there to be a picture as if the participant is still holding the ball. Is it possible to show a picture during the pretrialpause? (it already continues to show the player labels but I am not sure why). Kind regards, Esther Klinkenberg

(it already continues to show the player labels but I am not sure why). Kind regards, Esther Klinkenberg It's not possible to draw stimuli to the screen during /pretrialpause. What you can do is draw what you want displayed before then, i.e. at the end of the preceding trial, and set that stimulus to /erase = false. Otherwise, don't use the /pretrialpause approach but the /stimulustimes option I described earlier. Then you can draw stimuli to the screen whenever you want.
