Chapter 4
SENSORY SYSTEMS AND PERCEPTION
, Key Learning Goals
4.1 Explain how stimulus intensity is related to absolute thresholds and Just
Noticeable Differences (JNDs).
4.2 Describe the basic thrust of signal-detection theory.
4.3 Summarise the evidence on perception without awareness, and discuss its
practical implications.
4.4 Clarify the meaning and significance of sensory adaptation.
4.5 List the three properties of light and the aspects of visual perception they
influence.
4.6 Trace the routing of the signals from the eye to the brain, and explain the
brain’s role in visual-information processing.
.
,Key Learning Goals (continued)
4.7 Describe the role of the lens and pupil in the functioning of the eye.
4.8 Explain how the retina contributes to visual-information processing.
, ➢ Our sensory systems allow us to explore, understand a
respond to a multitude of stimuli in our individual
environments, giving each of us a unique experience o
world around us.
➢ Within your environment, you could just as easily hav
