Human Sensory Skills
Humans are able to sense all the energies that exist in the external world.
Transduction
Transduction is the process through which...
- electrochemical energy is sent to the brain.
- external energies are converted into electrochemical energy.
- sensory data are analysed.
Sensation
Which verb below is central to explaining the process of sensation?
- interpret
- organise
- recognise
- transduce
Perception
Drag the correct word into each space.

The Perceptual Process
Since we pay attention to the aspects of our environment that are most important and relevant to us, the perceptual process...
- allows us to form a completely accurate representation of the world.
- results in the same interpretation for all perceivers.
- permits us to increase our chances of survival.
Perception
Which set of words below refers ONLY to the process of perception?
- reception, transduction, transmission
- environmental energies, sensory receptors, sensory organs
- organising, interpreting, attributing meaning
- receive, transduce, transmit

My mother is a sheep expert, whereas I am a city person.
When my mother looks at sheep in a paddock, she formulates perceptual faster and more accurately than I possibly can. Yet the process of is similar for us both. Just like me, she detects through the on her retina. As we drive around the sheep, we both receive this from the external envirnoment. My mother, however, organises the more quickly and efficiently than I can. As a result of long experience, she the sensory information that has reached her much more rapidly than I can. such as motivation and prior learning are clearly at work. She attributes meaning to these sensory data and observes: "That sheep is fly-blown. We'll have to treat it."
