Questions and Answers
What is motion parallax?
What is retinal disparity?
It occurs because each eye transmits a slightly different image to the brain, inferring distance from the disparity.
Define convergence in terms of vision.
Convergence is the extent to which the eyes turn inward to focus on an object; closer objects require more convergence.

Study Notes
Motion Parallax
- A monocular cue where foreground objects appear to move faster than background objects.
- Allows perception of depth and motion without requiring three-dimensional input.
Retinal Disparity
- Caused by each eye sending slightly different images to the brain.
- The brain infers distance based on the disparity between the two images.
Convergence
- Refers to the inward turning of the eyes to focus on close objects.
- Greater convergence indicates closer distance, aiding depth perception.
Phi Phenomenon/Apparent Motion
- An optical illusion where a sequence of still images presented rapidly appears to be in motion.
- Relevant to motion perception but not to depth perception.
Attrition Bias
- Occurs when participants leave a long-term study, potentially skewing results.
- It can affect the validity and reliability of study findings.
Stroop Effect
- Demonstrates the difficulty of reconciling conflicting information related to colors.
- Highlights the interference that can occur when processing different attributes.
Absolute Mobility
- Refers to improvements in living standards across generations.
- Evaluates individual income in relation to parental income, indicating economic progress.
Strain Theory
- Suggests that social pressures without means for compliance can lead individuals to crime or deviance.
- Highlights the relationship between societal expectations and individual behavior.
Opponent-Process Theory
- Explains color vision through opposing retinal processes (red-green, yellow-blue, white-black).
- Some retinal cells react to one color while inhibiting the perception of its opposite.
