D: sensation
a physical feeling or perception resulting from something that happens to us or comes into contact with the body
D: perception
the ability to see, hear, or become aware of something through the senses and the way in which something is regarded, understood, or interpreted.
D: Distal Stimulus
- the physical object in the environment
D: Proximal Stimulus
- information about the distal stimulus is received by the sensory receptor cells . The proximal stimulus is a representation of the distal stimulus
D: Transduction
Transduction is the transformation of environmental physical energy into electrical energy in the nervous system
D: Neural Processing
How electrical signals are transmitted from one neuron to the next

What does the physiological approach to studying perception do & how?
Looks at what’s going on in the brain through anatomy tests such as fMRI, EEG, micro-stimulation or lesioning
What does the psychophysical approach to studying perception do & how?
Looks at what we actually perceive, eg through changing parts of stimulus to find people’s thresholds
2 Methods for testing thresholds
1: Method of adjustment - slowly changing a stimulus till someone can perceive something
2: Forced choice
