Perception I Flashcards
1
Q
Simple cells
A
Orientation selectiveDiscrete ON and OFF regions
Position sensitive
Linear – predict output from adding + and - region
2
Q
Complex cells
A
Orientation selective
Responds to spots all over receptive field
Not position sensitive
Non-linear – cannot predict output from addition
3
Q
Spatial Frequency –
A
The rate at which a pattern – the rate at which a pattern repeats itself (cycles per degree)
4
Q
Contrast/amplitude –
A
how black or white a pattern is (differences in lightest and darkest part divided by the average)
5
Q
Phase
A
starting point of a pattern
6
Q
Temporal Frequency
A
the rate at which a pattern repeats itself
7
Q
Orientation–
A
angle of presentation
