Parameters

FixationColor, BarColor, CueColor, TargetColor

The color of the fixation, bar, cue, target.

BarThick

The thickness of the bar.

FixationWidth

The width of the fixation cross.

CueThick

The thickness of the cue.

TargetWidth

The width of the target.

FixationDurationMin, FixationDurationMax

Minimum/Maximum duration of the fixation phase.

BarDurationMin, BarDurationMax

Minimum/Maximum duration of the bar phase.

CueDuration

Duration of cue.

CueToTargetDurationMin, CueToTargetDurationMax

Minimum/Maximum interval time between cue and target.

TargetDuration

Duration of target.

PostTargetResponseTime

The maximum time allows the subject to respond after the target disappears.

FeedbackDuration

Duration of the feedback

TotalTrial

Number of the total trials.

CatchTrialPerctg

The percentage of the catch trial(no target)(%).

CueTgtMatchPerctg

The percentage of the cue matches the target trial(%).

CueTgtSmObjctPerctg

The percentage of the target mismatches the cue, on the same object(%).

CueTgtDifObjctPerctg

The percentage of the target mismatches the cue, on the different objects(%). Set as 0 when it is a simplified task.

ScreenWidth, ScreenHeight

Width/height of the monitor screen in cm.

EyeToSreenDistance

Distance from the subject's eyes to the screen in cm.

VisualAngle

The degrees of visual angle.

AdjustContrastBy

Adjust the contrast of the target color by: 0 overall accuracy, 1 match accuracy, 2 non-match accuracy.

AdjustContrastTrialNum

The number of trials needed to calculate the accuracy for adjusting the contrast.

AccuracyUp

The up boundary of the accuracy.

AccuracyLow

The low boundary of the accuracy.

Simplified

Enable the simplified version, only has two squares rather than two bars.

SquareLength

The lenght of square in simplified version.

IsStairCase

Enable the Staircase.

DownCounts

Contrast decreases one step following the number of consecutive correct trials.

UpCounts

Contrast increases one step following the number of consecutive incorrect trials.

ProgressBar

Display progress bar.

ProgressBarHeight, ProgressBarWidth

Progress bar height/width in pixels.

ProgressBarBackgroundColor, ProgressBarForegroundColor

Color of progress bar background/foreground.

PhotoDiodePatch

Display a photo diode patch on the stimulus window. Recording from a photo diode located on that patch will allow triggering on actual stimulus delivery (see User_Reference:P3TemporalFilter#OnsetExpression).

PhotoDiodePatchHeight, PhotoDiodePatchWidth

Photo diode patch height/width in relative coordinates (between 0 and 1).

PhotoDiodePatchLeft, PhotoDiodePatchTop

Photo diode patch left/top position in relative coordinates (between 0 and 1).

PhotoDiodePatchShape

Photo diode patch shape: 0 rectangle, 1 ellipse.

PhotoDiodePatchActiveColor

Photo diode patch color when active (RGB color in format 0xrrggbb).

PhotoDiodePatchInactiveColor

Photo diode patch color when inactive, (RGB color in format 0xrrggbb, use 0xff000000 for transparent).
