Trial

// All miTime source files are wrapped inside define function // This function gives you access to the API object that we use to build the various tasks // If you want to know more about this, you can read up about AMD and check out http://requirejs.org/ define(['pipAPI'], function(APIconstructor) { var API = new APIconstructor(); // ### The trial sequence // The heart of any miTime script is the sequence. // Sequences are arrays of Trial objects. In this part of the tutorial we will see a simple sequence encompasing a single trial. API.addSequence([ // #### Trial structure /* the trial begins here */ { // The data property of the trial is used to keep user defined data regarding this trial. // It can be used to keep track of trial types, blocks, score etc. // It becomes incrementaly usefull with more advance features of the miTime. data: { myProperty: 'information', myOtherProperty: 'more information' }, // The input property of the trial is used to create the user interface. // In this case we tell the player to listen for hits on the space key. // Later on we will tell the player what to do when the space button is clicked. input: [ {handle:'space',on:'space'} ], // The layout property of the trial is used to display statick stimuli. // These stimuli are automaticaly displayed at the begining of a trial, and are not affected be user interactions. // This property holds an array of stimuli objects, in this case the stimuli are set to display words in the top left and bottom right of the screen. // We will learn more about Stimuli in a later tutorial. layout:[ {location:{left:0,top:0},media:{word:'top left'}}, {location:{left:'auto',right:0,top:'auto',bottom:0},media:{word:'bottom right'}} ], // The stimuli property of the trial holds stimuli that are dynamicaly displayed durring the trial. // These trials are not displayed by default, and can be affected by user interactions. // Like the layout property the stimuli property holds an array of stimuli objects. stimuli: [ {media :{word:'Hello world'}} ], // The interaction property of the trial is responsible for any interactions the user has through the trial. // Each interaction is composed of a propostition (a statement that is either true or false) // And of action to execute in case the condition is true. // We will learn more about this section in the condition and action tutorials. interactions: [ // 1. Display Stimulus { /* when we begin the trial (condition) */ conditions: [{type:'begin'}], /* show all stimuli (action) */ actions: [{type:'showStim',handle:'All'}] }, // 2. End trial on space click { /* when space is clicked */ conditions: [{type:'inputEquals',value:'space'}], /* end the trial */ actions: [{type:'endTrial'}] } ] } /* The trial ends here */ ]); /* this is where we close the sequence */ return API.script; }); /* don't forget to close the require wrapper */
