Have a look around you; what can you see? Does everything appear normal to you? What happens when we perceive things to be different from what they are? Differences in perception can be explained in psychology by using visual illusions! Illusions involve misinterpreting visual stimuli in the environment and what our brains think this information is. Our perception appears to vary from reality, and we can struggle to make sense of the things we see.

Differences in perception can be explained in psychology by using visual illusions! Illusions involve misinterpreting visual stimuli in the environment and what our brains think this information is. Our perception appears to vary from reality, and we can struggle to make sense of the things we see.
First, we will briefly explore perception and visual illusions in psychology.
Then we will look at some types of visual illusions.
After, we will see some visual illusions.
Next, we will identify explanations for visual illusions examples.
Finally, we will briefly examine some perception theories for possible causes of visual illusions.
Visual perception is a critical aspect of our survival. It allows us to explore and react to our environment. Visual illusions can confuse our brains into missing visual information or thinking we are seeing something that is not necessarily there, but what exactly do we mean by visual illusions?
Visual illusions are images or objects that alter our perception to be different from the picture's reality, as the 'illusion' does not make logical sense to our brain.
Perception can be explored from a psychological perspective using visual illusions by examining what kind of misinterpretations in stimuli affects the majority of people and why. This can help to understand why humans have evolved particular cognitive and visionary abilities and can contribute to creating design features that people find easy and enjoyable to view.
We can also begin to understand why visual illusions affect us all.
Visual illusions can vary in how and why they affect our perception. Some can be quite subtle and difficult to distinguish between the real and perceived image. In contrast, others are overwhelmingly tough to look at, where identifying a certain image or pattern is almost impossible.
A few types of visual illusions include:
Several kinds of visual illusions have been created and used by psychologists in perception research over the years. Fantastical images that test the brain's ability to make sense of illogical or ambiguous content have been created to explore perception. Visual illusion examples include:
Can you guess the visual trick in this illusion from the Italian psychologist Mario Ponzo?
Both of the parallel horizontal lines in the Ponzo illusion are the same length! The top horizontal line appears to be longer due to its placement converging at the top of the narrower part of the vertical lines.
Do you notice anything particular about the three lines in the illusion below?
The three long parallel lines are all the same length, as shown in the bottom image, with the lines highlighted in red. Many believe certain lines are longer due to the direction of the arrows at the end - outward arrows are often said to contain longer lines, although this is not the case.
Look at the image below. Can you see a vase or two faces?
The yellow part of the image shows a vase, but the black parts of the image make up a silhouette of two faces, one on the left and one on the right.
Can you spot the differences between the three circles below? Where do you think the visual illusion here is?
The illusion comes from the pink circle (the apparent position of person A) appearing directly opposite and smaller from the viewing point than the green circle (person B). The actual position of person A is further behind the apparent position. Because of the room shape and viewing angle, the distance is perceived to be shorter and, therefore, smaller.
Person A would look disturbingly small next to person B.
Look at the image below. How many triangles can you see?
There aren't any triangles in this image! Your brain fills in the gaps to create a large white triangle in between the gaps of the black circles. People often fill in gaps as well, to say there are three smaller black-lined triangles or one big triangle with a black outline too.
Which side of the cube below do you notice first?
People can perceive the cube to be angled towards the left and right.
There are several explanations for why we can misinterpret information seen in visual illusions like the ones above. Some of the common explanations include:
Depth cues can be monocular (using one eye), which gives a 2-dimensional image or binocular (using both eyes), which creates a 3-dimensional image.
There are two main theories of perception that we will briefly explore that can explain some possible causes for why visual illusions work:
Both of these theories can explain why we fall for visual illusions because the image we see either does not match up with information that we already have stored. So it isn't easy to interpret and understand because we automatically trust what we see in front of us as the truth.
Either way, our visual system gets easily overwhelmed and misinterprets the image.
Visual illusions are images or objects that alter our perception to be different from the reality of the picture, as the 'illusion' does not make logical sense to our brain.
Perception can be explored from a psychological perspective using visual illusions by examining what kind of misinterpretations in stimuli affects the majority of people and why.
Examples of illusions include the Ponzo, the Müller- Lyer, Rubin's Vase, the Ames room, the Kanizsa triangle and the Necker Cube illusions.
The three types of visual illusions include cognitive, physiological and literal illusions.
A visual illusion is caused by misinterpreting visual images based on how we might process information in the brain's attempt to make logical sense of reality. The image can be confusing if the information doesn't match how we interpret the world.
Visual illusions can tell us that perception can be different based on how we might process visual information. Our visual systems can get easily overwhelmed and so misinterprets the reality and perception of an image.
What is the definition of visual illusions?
Visual illusions are images or objects that alter our perception to be different from the reality of the picture.
What are 3 types of visual illusions?
What are cognitive visual illusions?
Cognitive visual illusions trick the subconscious mind based on how you normally infer and relate what you see to what you already know about the world. This causes your brain to think there is a certain image, even though it is not there or something else entirely.
What are physiological illusions?
Physiological visual illusions are generally geometric images containing so many visual cues that the brain sees different depths and lines of travel that they often look different every time, and some can appear to be moving.
What are literal illusions?
Literal visual illusions are made up of two images that are present at the same time. People can perceive them differently initially and often need the other image in the illusion pointing out to them to be able to distinguish between the first image noticed.
