Interposition Psychology
Binocular & Monocular Cues for Depth Perception

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.

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 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 also is known as depth perception that occurs when we perceived the object by one eye.

A binocular cue occurs when we see the object by 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 for depth perception. Monocular cues require a single eye to present two dimensions. All of the monocular cues play a vital role to experience 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 to steep for climbing. For example stereopsis, disparity, 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 a far 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 then 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 at 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 also termed as actual size which also helps to observe depth perception. We will see a smaller object farther away (if though it would 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.

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

If 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 from them.
