Common examples of mental images include daydreaming and the mental visualization that occurs while reading a book. Another is of the pictures summoned by athletes during training or before a competition, outlining each step they will take to accomplish their goal.
Most people can readily conjure images inside their head - known as their mind's eye. But this year scientists have described a condition, aphantasia, in which some people are unable to visualise mental images. Niel Kenmuir, from Lancaster, has always had a blind mind's eye. He knew he was different even in childhood.
We use the term 'mental imagery' to refer to representations and the accompanying experience of sensory information without a direct external stimulus. Such representations are recalled from memory and lead one to re-experience a version of the original stimulus or some novel combination of stimuli.
Three characteristics of mental imagery and their links with function were studied: speed, vividness and colors.
When we form a mental image we seem to be able to manipulate them and we seem to be solving problems some times by means of manipulating them. Mental images can be quite detailed but they tend to be less detailed than actual perception.
Most people, when asked to form an image of a person they're familiar with, can see it within their mind. In other words, it's a visual, mental experience – similar to what we would see if the person were in front of us. But it turns out that this isn't true for everyone.
Patients with posttraumatic stress disorder, other anxiety disorders, depression, eating disorders, and psychosis frequently report repeated visual intrusions corresponding to a small number of real or imaginary events, usually extremely vivid, detailed, and with highly distressing content.
If you ask most of the world's population to picture a person, place, or thing, they have no problem conjuring a mental image in their mind's eye. But for a small percentage of the population (estimates range anywhere from 1 to 5%), visualizing or imagining images is impossible.
The difference between hallucinations and mental images lies in the possibility to control the perceptual experience. While hallucinations typically occur beyond intention and control (Bentall 1990), mental images are actively generated by the subject and can thus be intentionally controlled.
“There are also large individual differences in our ability to create images in our mind,” says Dr Keogh. “For some people, the image is so clear it's almost like seeing; for others, it's weak and dim. Some people can't see anything at all.
Aphantasia is a phenomenon in which people are unable to visualize imagery. While most people are able to conjure an image of a scene or face in their minds, people with aphantasia cannot.
Scientists refer to this inability as aphantasia. Most studies that have investigated this phenomenon are based on questionnaires that reveal the subjective experiences of those affected. Cognitive tests and brain scans also indicate, however, that some people truly do lack the ability to form mental images.
Even if it's a little too late, one of the best things you can do is to physically distance yourself from the situation. “Right after we experience something disturbing, you need to remove yourself from that trigger,” Ankrom said. “Get away from the computer, don't view that image again, and go for a walk.”

Self-image is the personal view, or mental picture, that we have of ourselves. Self-image is an “internal dictionary” that describes the characteristics of the self, including such things as intelligent, beautiful, ugly, talented, selfish, and kind.
Waking Imagery
This is the most common type of image we experience. We see a picture with the “mind's eye.” This waking imagery is very subtle. Often we are not even aware of it.
You may have hallucinations if you: hear sounds or voices that nobody else hears. see things that are not there like objects, shapes, people or lights. feel touch or movement in your body that is not real like bugs are crawling on your skin or your internal organs are moving around.
Symptoms of psychosis include delusions (false beliefs) and hallucinations (seeing or hearing things that others do not see or hear). Other symptoms include incoherent or nonsense speech and behavior that is inappropriate for the situation.
Mental imagery is the representation that results from perceptual processing that is not triggered directly by sensory input. So we get mental imagery when the first stop of perceptual processing happens without direct sensory input.

When you close your eyes, you may be able to “see” colors, shapes, and light. Some of the images may also move or create a swirling effect. Such visual effects are sometimes called closed eye hallucinations because such objects aren't literally in front of you.
Mental imagery provides an essential simulation tool for remembering the past and planning the future, with its strength affecting both cognition and mental health. Research suggests that neural activity spanning prefrontal, parietal, temporal, and visual areas supports the generation of mental images.
Introduction. Intrusive mental imagery is a transdiagnostic process (1) present in many psychological disorders including trauma-related disorders; anxiety, mood, and eating disorders; as well as severe mental health problems, such as bipolar disorder and psychosis.
Examples: A flash of a scene of your loved ones bloodied on the floor as you murder them with a knife. An image of the pictures on your wall not being displayed with perfect symmetry. A vision of germs crawling all over your body when feeling contaminated.
