Coder

Note

These do not teach you about Python per se, and you are recommended also to learn about that (Python has many excellent tutorials for programmers and non-programmers alike). In particular, dictionaries, lists and numpy arrays are used a great deal in most PsychoPy experiments.

You can learn to use the scripting interface to PsychoPy in several ways, and you should probably follow a combination of them:

• Basic Concepts: some of the logic of PsychoPy scripting
• PsychoPy Tutorials: walk you through the development of some semi-complete experiments
• demos: in the demos menu of Coder view. Many and varied
• use the Builder to compile a script and see how it works
• check the Reference Manual (API) for further details
• ultimately go into PsychoPy and start examining the source code. It’s just regular python!

• Presenting Stimuli
  • Stimulus objects
  • Setting stimulus attributes
  • Timing

• Logging data
  • Log levels and targets
  • Updating the logs
  • AutoLogging
  • Manual methods
  • Using a custom clock for logs
• Handling Trials and Conditions
  • TrialHandler
  • StairHandler
• Global Event Keys
  • Adding a global event key (simple)
  • Adding a global event key (advanced)
  • Indexing
  • Number of active event keys
  • Removing global event keys
  • Global shutdown key
  • A working example
