“Measuring perception” tutorial
In this online tutorial, we will investigate how we can measure how people perceive the world. We will be focusing on a framework called signal detection theory, which is a method that allows us to measure the sensitivity to particular visual stimulation. We will concentrate on the perception of motion.
This primary learning outcome that is addressed in this tutorial is for you to be able to:
- Explain how motion sensitivity can be measured and describe the importance of considering response bias.
This tutorial also expands on the following learning outcomes, which have been covered in lectures:
- Define ‘motion’ and depict and interpret space-time representations.
- Construct and explain the operation of a ‘delay-and-compare’ motion detection circuit.
What to do
The tutorial is organised in a set of sections. They build on one another, so it is best if you work through them in order. Some will require you to interact with graphs, and some will require you to note down your perception of patterns shown in videos.
How long to devote
Although this is an online tutorial, the intention is that it is no less substantial than your regular face-to-face tutorials. As such, you should expect to devote the usual tutorial time (2 hours) to working through this online tutorial.
What to do afterwards
To test your achievement of the learning outcomes for this tutorial, there is a short quiz on Moodle for you to complete. Note that this quiz does not contribute any marks towards your final grade for the course, but completion is necessary to register your ‘attendance’ at this tutorial. Quizzes must be submitted by 9am on Monday September 3 in order for the tutorial to be registered as attended.
