16 Questions
Which approach is described for creating models?
Collect Data, Test Predictions, Revise
What is the purpose of models in the context of human performance?
To isolate components for closer examination
Why are models of human performance described as an inductive process?
Because they start from specific observations to form broader generalizations
What is the function of the Human Visual System as described in the text?
To capture light and transmit it to the brain
Based on the text, what would be a consequence if light is not captured by the retina?
Blurry vision
According to Fitts’s Law, what can be predicted based on the model?
Human reaction time in a pointing task
Which type of light-sensitive receptors are primarily for night vision and perceiving movement?
Rods
What is the function of the edge of the retina which is dominated by rods?
Detecting motion of threats in the periphery
What is the main disadvantage of lens yellowing with age and absorbing short wavelengths?
Reduced sensitivity to blue light
What does the fixation on a small blue object yield, based on the distribution of photopigments in the retina?
Disappearance of the blue object
What determines the brightness mainly in color perception?
$Y = 0.3 Red + 0.59 Green + 0.11 Blue$ formula
What makes saturated colors require more focusing than desaturated colors?
Different wavelengths of light focused at different distances behind eye’s lens
How are edges and shapes detected in vision?
$Y = 0.3 Red + 0.59 Green + 0.11 Blue$ formula
What is the main implication regarding the detection of blue edges and shapes?
$64%$ distribution of red photopigments affects detection
What is the effect of constant refocusing on saturated colors?
$64%$ distribution of red photopigments causes fatigue
What is the main disadvantage of insensitivity to short wavelengths in vision?
$64%$ distribution of red photopigments is compromised
