Introduction
To help facilitate the use of LabMaestro as an experiment builder, we demonstrate the variety of flexible designs that can be replicated using this software through a series of template experiments. LabMaestro Project Files (*.lm) containing these template experiments are also available for download, should you wish to explore these templates on your own computer.
Template Experiments
Tutorials
The following tutorials explain higher-level concepts of the LabMaestro Experiment Builder and are a useful resource to learn how the program works.
Regions, Patterns and Static Psychophysical stimuli
This small tutorial shows how to combine Regions and Patterns to create common visual stimuli.
Calibration with TRACKPixx3
This tutorial shows how to calibrate your TRACKPixx3 eye tracker and validate its calibration accuracy.
Monitor Pixel Density and Degrees of Visual Angle
This tutorial explains the theory behind Degrees of Visual Angle as a unit and how to use it to control stimulus appearance in the LabMaestro Experiment Builder.
Rapid Invisible Frequency Tagging (RIFT) stimuli
A tutorial on how to use the PROPixx to generate stimuli that flicker imperceptibly quickly.
High Bit Depth Rendering
A tutorial on how to use High Bit Depth rendering mode to increase the precision of colour rendering.
High Refresh Rate Rendering
A tutorial on how to present dynamic stimuli using the High Refresh Rate visual rendering modes of the PROPixx.
Customizing Stimuli with Mathematical Functions and Expressions
A tutorial on how to use LabMaestro Expressions to produce visual stimuli distinct from the available Patterns.
Playing Audio
A small tutorial on how to play audio files using LabMaestro.
Understanding CLUTs, M16 Mode and Colour Transparency
A tutorial on elements related to colour definition, perception and rendering through the LabMaestro application.
Recording and Plotting Pursuit Data
A tutorial showing how to record dynamic eye movement data while looking at a moving target.
Experiment Designs
The following templates show how LabMaestro can be used to replicate vision science experiment designs.
Phenomenal Coherence of Moving Patterns
This replication of Adelson & Movshon (1982) shows how two moving patterns can create the perception of new congruent and/or incongruent patterns when combined.
Illusory Apparent Motion
This replication of Davidenko et al. (2017) shows that randomly moving noise can be perceived as moving in a congruent pattern after prior exposure to a moving stimulus.
Contrast Sensitivity
A template experiment to measure contrast sensitivity in participants using Gabor patches of varying spatial frequencies.
Gaze Contingent Window
A template experiment demonstrating how to use gaze position to define a gaze-contingent window that can hide the central or peripheral visual fields.
Free Viewing Experiment
A template experiment based on Yarbus (1967), comparing fixation patterns when viewing images across three conditions.
Saccade to Target Experiment
A template experiment measuring reaction time between the appearance of a target stimulus and a saccade to the target position. Coming soon!
Controlling Experiment Flow using the TRACKPixx3
This template experiment shows how to use gaze position to determine when to advance the experiment.
Stroop Effect
A template experiment based on Stroop (1935) to measure the effect of incongruent colour and word information on error rates and reaction times.
Motion Blur
Coming soon!
