Whether to allow user to pause the study during the test segment and restart from intro; otherwise, user can pause but this frame will end upon unpausing. Applies to pausing during both image display and calibration segments. Pausing is always allowed during the intro.

minimum amount of time to show attention-getter in seconds. attention-getter intro video will be shown for at least this long, and also until any intro audio finishes playing and a webcam connection is established.

List of audio types to expect for any audio specified just with a string rather than with a list of src/type pairs. If audioTypes is ['typeA', 'typeB'] and an audio source (e.g. introAudioSources) is given as [{'stub': 'intro'}], then introAudioSources will be expanded out to

                [
                       {
                           src: 'baseDir' + 'typeA/intro.typeA',
                           type: 'audio/typeA'
                       },
                       {
                           src: 'baseDir' + 'typeB/intro.typeB',
                           type: 'audio/typeB'
                       }
               ]

Base directory for where to find stimuli. Any image src values that are not full paths will be expanded by prefixing with baseDir + img/. Any audio/video src values that give a value for 'stub' rather than 'src' and 'type' will be expanded out to baseDir/avtype/[stub].avtype, where the potential avtypes are given by audioTypes and videoTypes.

Note that baseDir SHOULD include a trailing slash (e.g., http://stimuli.org/myexperiment/, not http://stimuli.org/myexperiment)

Sources Array of {src: 'url', type: 'MIMEtype'} objects for calibration audio, played from start during each calibration segment (only used if isCalibrationFrame)

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and audioTypes values; see audioTypes.

length of single calibration segment in seconds (only used if isCalibrationFrame)

Sources Array of {src: 'url', type: 'MIMEtype'} objects for calibration video, played from start during each calibration segment (only used if isCalibrationFrame)

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and videoTypes values; see videoTypes.

URL of image to show at center, if any. Can be a full URL or a stub that will be appended to baseDir + img/ (see baseDir).

Sources Array of {src: 'url', type: 'MIMEtype'} objects for audio played after trial ends (optional, intended for use on last trial to let parents know they can open their eyes)

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and audioTypes values; see audioTypes.

Sources Array of {src: 'url', type: 'MIMEtype'} objects for audio played when study is paused due to not being fullscreen

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and audioTypes values; see audioTypes.

Sources Array of {src: 'url', type: 'MIMEtype'} objects for instructions or any other audio during attention-getter video

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and audioTypes values; see audioTypes.

Whether to do calibration instead of a static image display. If this is true, then provide calibrationLength, calibrationAudioSources, and calibrationVideoSources as well.

URL of image to show on left, if any. Can be a full URL or a stub that will be appended to baseDir + img/ (see baseDir).

Sources Array of {src: 'url', type: 'MIMEtype'} objects for audio played upon pausing study

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and audioTypes values; see audioTypes.

URL of image to show on right, if any. Can be a full URL or a stub that will be appended to baseDir + img/ (see baseDir).

Sources Array of {src: 'url', type: 'MIMEtype'} objects for audio played during test trial. (Only used if not isCalibrationFrame.)

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and audioTypes values; see audioTypes.

length of preferential looking trial in seconds. (Only used if not isCalibrationFrame.)

Sources Array of {src: 'url', type: 'MIMEtype'} objects for audio played upon resuming study

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and audioTypes values; see audioTypes.

Sources Array of {src: 'url', type: 'MIMEtype'} objects for attention-getter video

Can also give a single element {stub: 'filename'}, which will be expanded out to the appropriate array based on baseDir and videoTypes values; see videoTypes.

List of video types to expect for any video specified just with a string rather than with a list of src/type pairs. If video is ['typeA', 'typeB'] and an video source is given as {['stub': 'attn']}, then the video source will be expanded out to

                [
                       {
                           src: 'baseDir' + 'typeA/attn.typeA',
                           type: 'video/typeA'
                       },
                       {
                           src: 'baseDir' + 'typeB/attn.typeB',
                           type: 'video/typeB'
                       }
               ]
