Waarnemen en bewegen HC 1: introduction to perception
“Our goal is to understand the human model, starting with the detectors—the eyes, ears, skin
receptors, and receptors in the nose and mouth—and then moving to the computer— the brain.”
“… one of the things that you will learn as you study perception is that everything you see, hear,
taste, feel, or smell is the result of the activity in your nervous system and your knowledge gained
from past experience.”
- Perception: conscious experience that results from stimulation of the senses
- Idea: perception depends on the properties of the sensory receptors
- Sensation: is often identified as involving simple ‘elementary’ processes that occur right at
the beginning of a sensory system, as when light stimulates receptors in the eye.

- Perception: is identified with complex processes that involve higher-order mechanisms such
as interpretation and memory that involve activity in the brain. Luxer (driehoek)
The Perceptual Process
1. Distal stimulus
2. Proximal stimulus
3. Receptor processes -> transduction
4. Neural processing
5. Perception
6. Recognition
7. Action
- Knowledge
1. Distal stimulus: it is called distal because it is distant out there in
the environment
2. Proximal stimulus is created: light is reflected and focused, it is in
proximity to the receptors
- The principle of transformation: stimuli and responses created
by stimuli are transformed, or changed, between the
environmental stimulus and perception.
- Principle of representation: everything a person perceives is based not on direct contact with
stimuli but on representations of stimuli that are formed on the receptors and the resulting
activity in the person’s nervous system
3. Receptor processes -> transduction
- Transduction: the transformation of one form of energy (light energy) to another form
(electrical energy)
- Shaping of perception by the properties of visual pigments
in the receptor’s outer segments. The end result is an
electrical representation of the tree

4. Neural processing: primary receiving areas
- Neurons transmit signals and change (or process) the
signals
- Neural processing: the changes in these signals that occur
as they are transmitted through this maze of neurons
- Electrical signals are transmitted into conscious experience
