About us§

Credits:
  • many other people have contributed to the PsychoPy project (Jeremy Gray, Mike MacAskill, Richard Höchenberger, Sol Simpson being the biggest contributors)
  • Nottingham University have been paying Jons salary while PsychoPy was written
  • Wellcome Trust recently gave us a grant to improve this a LOT

About the workshop§

Not aiming to teach you all of PsychoPy

Hopefully give you some ideas about what’s possible

Getting to know PsychoPy§

5

What is PsychoPy?§

It’s Psychology software in Python

PsychoPy is several things:
  • a library for use in Python scripts
  • an editor including Python to edit scripts
  • an application with a graphical user interface (GUI) for building experiments

It’s, itself, entirely written in Python

6

Goal of PsychoPy§

The aim is to enable scientists to run as wide a range of experiments as possible, as easily as possible, with standard computer hardware.

A single piece of software:
  • precise enough for psychophysics
  • intuitive enough for undergraduate psychology
  • flexible enough for everything else
  • capable of running studies in the lab or online
7

Choice of interface§

It’s hard to make something easy enough for undergrads and novices but flexible enough for everything else.

PsychoPy provides two main options, for programmers and non-programmers, but there are also ways to combine the two.

PsychoPy is written in the Python programming language

Choice of interface§

The Coder view is used to create experiments from Python scripts

Choice of interface§

The Builder view is used to create experiments visually

Why do people Code?§

Why do people Build?§

What do we do?§

I (Becca) and Jon still use both Builder and Coder on a regular basis.

My experiments I are almost always in Builder, with added Code Components. I don’t ever break out and switch to pure code. I use code for other things (e.g. making my ‘conditions’ .csv files, making stimuli)

Going further§

Builder interface:
Python programming (for experimental psych):

So, let’s go on and learn some Building better experiments
