Match List I with List II

List I	List II
A. A laboratory device for testing depth in infants and young animals	I. Perceptual adaptation
B. Refers to the differences in two eyes' location of corner angles	II. Horizontal disparity
C. Refers to two points which fall on non-corresponding retinal positions one nearer and the other farther	III. Vertical disparity
D. Perceptual adaptability to adjust to an artificially displaced visual field	IV. Visual cliff

Correct option is D

The correct answer is (d) A-IV, B-III, C-II, D-I.
a. A → IV (Visual cliff): The visual cliff is a laboratory device designed to test depth perception in infants and young animals. It uses a displaced visual field to observe how the subject reacts to the perceived "cliff".
b. B → III (Vertical disparity): This refers to the difference in retinal positions of objects when viewed with both eyes, which results in vertical disparity when the points are in non-corresponding retinal positions.
c. C → II (Horizontal disparity): The concept of horizontal disparity refers to the difference in the location of two objects' retinal images in each eye. It is a key cue for depth perception and occurs when objects are viewed at different angles.
d. D → I (Perceptual adaptation): Perceptual adaptation is the ability of an individual to adjust to a distorted or artificially displaced visual field, such as when wearing prisms that alter vision.

Information Booster

Visual Cliff
1.1. The visual cliff is used to study depth perception in infants and animals.
1.2. The experiment involves a glass table with one side appearing as a steep drop-off (the "cliff").
1.3. Infants and animals typically avoid the "cliff," demonstrating their ability to perceive depth.
1.4. The visual cliff is a classic experiment in developmental psychology.

Vertical Disparity
2.1. Refers to the vertical difference in the position of objects on the retina when each eye is focused on different points.
2.2. It is a cue for depth perception and is important for understanding relative distance between objects.
2.3. Vertical disparity helps us judge whether an object is closer to or farther away from the viewer.
2.4. It plays a crucial role in 3D vision.

Horizontal Disparity
3.1. Horizontal disparity occurs when the two eyes view an object at slightly different horizontal angles.
3.2. This difference helps the brain perceive depth and the distance between objects.
3.3. It is one of the main cues used for binocular depth perception.
3.4. Greater horizontal disparity corresponds to objects being closer to the observer.

Perceptual Adaptation
4.1. Perceptual adaptation is the process of adjusting to a distorted visual field.
4.2. It is demonstrated when a person adjusts to prisms that shift the visual field or to other visual distortions.
4.3. The brain's ability to adjust is an essential aspect of visual processing.
4.4. This type of adaptation shows the flexibility of the perceptual system.
