Deaf people can call up volitional imagery of someone else signing to them in the same way that a hearing person may be able to imagine the sounds of someone speaking to them.
Primarily though, most completely deaf people think in sign language. Similar to how an “inner voice” of a hearing person is experienced in one's own voice, a completely deaf person sees or, more aptly, feels themselves signing in their head as they “talk” in their heads.
People who have been completely deaf since birth cannot experience true auditory hallucinations. Rather, they experience visual or physical hallucinations such as moving lips, sign language movements, body motions, and facial expressions that they interpret as an expression of the voice.
Different brains experience internal speech differently (and some not at all) Most people have some level of internal monologue going through their heads throughout their day, however there is a small group of people who do not experience any self-talk at all.
Many people who are profoundly deaf can still hear planes, dogs barking, etc. Hearing a sound does not mean that Deaf people can understand speech. A person with a significant hearing loss generally has difficulty or inability to hear speech even when aided.
Some Deaf people have an auditory component in their dreams
If people become Deaf after the age of five, they will probably have an auditory component in their dreams, even after a severe hearing loss. This might range from short auditory flashes to complete auditory recreations.
Hearing-impaired (also referred to as deaf) people think in terms of their “inner voice”. Some of them think in ASL (American Sign Language), while others think in the vocal language they learned, with their brains coming up with how the vocal language sounds.
Hearing voices may be a symptom of a mental illness. A doctor may diagnose you 'psychosis' or 'bipolar disorder'. But you can hear voices without having a mental health diagnosis. Research shows that many people hear voices or experience other types of hallucinations.
Voice hearing is often called auditory verbal hallucinations in the research literature. Hearing a voice or voices is not an uncommon occurrence with between 0.6% and 84% of the population hearing voices that other people don't.
There are many significant factors that can cause hearing voices. The major factors that contribute to this condition are stress, anxiety, depression, and traumatic experiences. In some cases, there might be environmental and genetic factors that cause such hearing of voices.
There can be “voices that are more thought-like,” says Jones, “voices that sound like non-human entities, voices that are perceived as the direct communication of a message, rather than something you're actually hearing.” Voices aren't always voices, either. They can sound more like a murmur, a rustle or a beeping.
Hearing voices is sometimes called an 'auditory hallucination'. Some people have other hallucinations, such as seeing, smelling, tasting or feeling things that don't exist outside their mind.
Auditory hallucinations happen when you hear voices or noises that aren't there. The sounds you hear may seem real, but they're not. A person may perceive auditory hallucinations as coming through their ears, on the surface of their body, in their mind or from anywhere in the space around them.
FACT: Some deaf people speak very well and clearly; others do not because their hearing loss prevented them from learning spoken language. Deafness usually has little effect on the vocal chords, and very few deaf people are truly mute. MYTH: Hearing aids restore hearing. FACT: Hearing aids amplify sound.
Patients who suffer from schizophrenia often have auditory hallucinations. They hear voices that are not there. Many times these hallucinations say things like “You are a terrible person, you are lazy, you are a waste of time” and other derogatory or critical remarks.
Psychology professor Russell Hurlburt reports that 30 to 50% of people have an inner voice. Most people believe that inner speaking does not occur passively. It is something you do consciously. A study involving ten beeps a day for three days shows that some participants have no inner monologue.
They are commonly experienced by those with psychiatric disorders and can be seen in up to 75% of people with schizophrenia. It is also caused by brain tumors, common types of street drugs (e.g., MDMA, LSD), alcohol use, and epilepsy. Auditory hallucinations may also be experienced when falling asleep or waking.
In most people with schizophrenia, symptoms generally start in the mid- to late 20s, though it can start later, up to the mid-30s. Schizophrenia is considered early onset when it starts before the age of 18. Onset of schizophrenia in children younger than age 13 is extremely rare.
Although psychosis is rare, many people may hear voices that other people cannot hear or experience other hallucinations. Hearing voices or having other hallucinations does not mean that a person is definitely experiencing psychosis.
Have you ever wondered how Deaf people wake up in the morning? The most natural way is from the sun itself. Leave curtains open to shine through windows to brighten up the room and Deaf people can sense the lighting in their sleep. Some have their own internal clock that wakes them up.
Interestingly, a person who is Deaf but also learned to speak through vocal training will sometimes not only think in sign language but also in spoken language. Most hearing people experience their own voice in a silent way when thinking, which is also called “internal monologue”.
Approximately 90% of people who have tinnitus also have hearing loss. People often do not notice a hearing loss but do notice “ringing in their ears.”
