Interposition Psychology | Binocular & Monocular Cues for Depth Perception

682

The objects of interposition psychology overlap another, causing us perceives depth. It is present everywhere. Monocular position and overlapping are a type of monocular cue in which one figure or object overlapped others. A monocular depth cue may occur when we visually see the two objects in the same line. Also, it is called a relative position. There are various causes of lack of depth perception, which you can get the remedy from proper treatment. Let’s check the details.

Interposition psychology definition:

According to Oxford reference, “Interposition Psychology” is the placement of monocular cues of visual depth perception and overlapping another object. The overlapping object looks closer than the monocular cue, which is the backend.

Interposition psychology example:

From Interposition psychology, we view the front object near and the behind object farther away. For example: see the two triangles. Which one do you think near to you? And which one is further away?

Interposition Psychology
You can see the Green triangle near you than the Blue triangle.

Types of interposition psychology:

There are various perception ways like depth perception or molecular cues and binocular cues, and so one.

A monocular cue is also known as depth perception when we perceive the object with one eye.

Conversely, A binocular cue occurs when we see the object with two eyes for depth perception.

How we use monocular cues?

In our everyday life, we use monocular cues by texture, gradient, linear or aerial perspective, etc. Different artists and graphic designers use these tools. According to size and shape, we can visualize a picture in different ways.

Monocular cues play a great contribution to depth perception. Monocular cues require a single eye to present two dimensions. All monocular cues play a vital role in experiencing a scene, our depth, and distance perception. Also, we can interoperate the exact position by comparing the other object in the scene.

How we use binocular cues?

Binocular cues involve using two eyes to be processed by the brain to recognize the perceived depth or distance. For this reason, most of the cues are used to make an art of illusion in two-dimensional depth perceptions.  These cues are important to get the idea too steep for climbing, such as stereopsis, disparity, and eye convergence.

What is convergence binocular cues?

Convergence binocular cues are the process where our eyes rotate inwards for getting a clear focus on an object.  We can recognize afar or a near object through our brain by rotating the eyes. The degree of rotation is important to make concepts about the objects. When we see a near object, we require rotating in a greater degree of inward than objects farther from our face.

How do we see the perceived depth?

As a psychology student and graphic designer, I frequently use various tools that make the art different. A small change of a big image can change the total theme perspective. To see the perceived depth, we use a few common monocular cues, which are mentioned below.

Relative size and shape:

The relative size is important for depth perception. For example, if two objects keep the same size, the closest object will be noticed first because it is judged larger for being near. This can occur for both:

  • Two-dimensional image or shape and
  • Three-dimensional image or shape.
Absolute size Vs. Familiar size:

Absolute size is also termed as actual size, which also helps to observe depth perception. We will see a smaller object farther away (if thought it would be familiar to us) than a larger object.

There are also various monocular which makes the perceptional difference; some of them are:

  • Elevation
  • Texture gradient
  • Motion parallax
  • Aerial perspective
  • Linear perspective
  • Overlap or interposition
  • Shading and lighting

Without interposition psychology, we could not think or function. Our cognitions could not work.

What causes a lack of depth perception?

lack of depth perception depends on numerous conditions. These include Amblyopia: Also called “lazy eye,” this is a situation in which one eye is weaker than the other. This typically occurs because of abnormal vision growth in childhood and features reduced vision in one or both eyes.

Some other conditions that can cause a lack of depth perception problems include:

  • Blurry vision, usually in one eye.
  • Strabismus.
  • Trauma to one eye.
  • Poor depth perception from the barth.
  • Nerve problems in one eye.

Often, when a person encounters poor depth perception, the treatment is as simple as adjusting refractive faults to enhance overall vision. Clear vision and improved depth perception can be obtained through prescription lenses, such as glasses or contact lenses.

How to improve depth perception?

 Two important ways to improve Depth Perception:

  • Eye Rolling: Rolling your eyes around independently and regularly helps stimulate the eye muscles.
  • Shifting Your Gaze: Slowly shifting your gaze from one object to another, often in combination with eye-rolling, sharpens understanding, and perception.

In short, we can say that Interposition psychology is a perceptional signal that the closure object shows first as further objects stay covered.


Suppose you want to know more about Interposition Psychology, which is related to sensation and perception. I will suggest an important book title, ” Sensation & Perception” 4th Edition. The Author is Jeremy M. Wolfe, and the other seven writers, Publisher: Sinauer Associates, is an imprint of Oxford University Press. Similarly, you can get a clear knowledge about our perceptional thought, behavior, feeling, and cognitive activity. The book is on amazon. You can buy it from them.

Frequently Asked Question

1. What is interposition in psychology?

Interposition is a monocular cue that happens when one object makes a contradiction for another. Also, this causes the item that is somewhat related to resemble more distant.

 2. What does the MCAT test you on?

The MCAT is computer-based tests. Also, this works for physical and biological sciences, verbal reasoning, and writing skills. To get a better understanding, you should test your capability to distinguish sociocultural, physiological, and emotional effects on your behavioral response and social communications and how people process emotions, anxiety, pressure, and stress.

  • Max. Score: 528.

3. What is the retinal disparity in psychology?

Retinal disparity is one of the most important cues that humans use to perceive depth. Precisely, it includes both eyes and refers to the difference between the view that each eye experiences a given object or picture.

 4. Which is called a binocular cue for the perception of distance?

Binocular cues include stereopsis, eye convergence, disparity, and yielding depth from binocular vision through parallax exploitation. On the other hand, Monocular cues include size: distant objects subtend smaller visual angles than near objects, grain, size, and motion parallax.

5. Which is most helpful in perceiving the distance of objects far away from you?

Binocular vision is better at perceiving motion from a distance. The eye sees a two-dimensional image in action in the monocular vision, sufficient at near distances but not farther away.

6. Do you lose depth perception with age?

Research shows that both motion processing and pursuit eye movement functions are affected by age. Also, older adults may be less sensitive to the depth from motion parallax.
