== Overview ==

'''PsychoPy''' is an open-source software tool to create and run behavioral and cognitive experiments. It supports both a desktop application and online experiments via '''Pavlovia''', enabling participants to take part remotely in web browsers without requiring local installation.

PsychoPy provides a '''Builder view''' for drag-and-drop experiment design, suitable for users without coding experience, and a '''Coder view''' for advanced customization with [[Python]]. Its precise timing and synchronization features make it a standard tool for psychology and neuroscience research.

== Getting Started ==

# Install PsychoPy
# Choose Builder or Coder view depending on your experience and needs
# Create a new experiment and define routines and stimuli
# Run the experiment locally or upload it to Pavlovia for online participation
# Download and analyze collected data

== Key Concepts ==

* '''Builder view:''' Visual interface for constructing experiments using components like stimuli, responses, and routines.
* '''Coder view:''' [[Python]]-based interface for scripting and customizing experiments.
* '''Stimuli:''' Text, images, sounds, or videos presented to participants.
* '''Responses:''' Inputs recorded from participants, such as key presses or mouse clicks.
* '''Timing precision:''' Automatic synchronization with the display refresh rate to ensure accurate stimulus presentation.
* '''Pavlovia:''' Online platform to host, run, and collect data from experiments in a web browser.
* '''Experiment routines:''' Sequences of events, such as stimuli presentation and response recording.

== Main Uses ==

* Create and run behavioral, cognitive, and perceptual experiments
* Present stimuli with high temporal precision
* Record participant responses accurately
* Deploy experiments online via Pavlovia for remote participation
* Test and prototype experiments quickly in Builder view before customizing in Coder view

== Why It Matters ==

* Enables rapid creation of experiments with minimal coding
* Supports both local and online participant testing
* Provides precise control over stimulus presentation timing
* Facilitates reproducibility and sharing of experimental workflows

== When You Will Use It ==

* Designing and testing new behavioral experiments
* Running experiments in the lab or remotely via web browsers
* Collecting and analyzing participant data
* Customizing experiments with [[Python]] for advanced features

== Good Practices ==

* Test experiments for timing accuracy before running actual sessions
* Keep routines and code well-organized for reproducibility
* Use descriptive file names and structured folders for experiments
* Backup all experiment files and collected data
