Perception

Everything we feel, think, and do depends on sensations and perception. In this module of the course, we will further explore the field of perception, focusing on visual and auditory perception. We first discuss the processes involved in organizing visual sensations into coherent objects and then assigning meaningful category labels to these objects (lectures 1 and 2). We then talk about the mechanisms of attention that select certain aspects of a scene for further processing while ignoring others (lectures 3 and 4). It is often said that humans are visual animals, but a world where nothing makes a sound is hard to imagine. Accordingly, the final two lectures cover the basic qualities of sound waves and the basic operating characteristics of the auditory system (lecture 5) as well as cues to sound localization and processes involved in auditory scene analysis (lecture 6).

The lectures are accompanied by a 2-hour lab and a 1-hour tutorial.

 

Lecture 55:
Visual Pathways and Processing
Here we will cover the visual pathways and early visual processing.
David Hume Tower Lecture Theatre C
Monday, 18 March, 2019 - 11:10 to 12:00
Lecture 56:
Two Visual Systems
We will look at the effects of damage to the “what” and “where” pathways. We will discuss the implications of two visual systems on experimental design.

Tuesday, 19 March, 2019 - 11:10 to 12:00
Lecture 57:
Visual Attention
In the next two lectures, we discuss theories of how attention is deployed or captured. In the first lecture we will review models of attention and disorders of attention.

Lecture 58:
Visual Attention II
We will discuss eye-tracking techniques and how studying attention outside of the lab has informed of understanding of the mechanisms used to control attention.

Lecture 59:
Auditory Perception
We introduce intensity and frequency as the two defining physical characteristics of sound. After touching upon the physiology of the auditory system, we then discuss how the listener subjectively perceives the two basic properties of sound waves.

Lecture 60:
Sensory Integration
Here we will demonstrate the contribution of multiple sensory modalities to perception.

Learning Outcomes: 

By the end of the course, students should:

  • Understand how midlevel vision organizes the elements of a visual scene into groups that we can then recognize as objects
  • Understand that attention to an object is critical in recognition of that object
  • Know about experimental paradigms to study and model attention
  • Understand the basic physics and psychophysics of hearing and how we use auditory information to learn about our environment
