The onset of claustrophobia has been attributed to many factors, including a reduction in the size of the amygdala, classical conditioning, or a genetic predisposition to fear small spaces.
Emetophobia is a phobia that causes overwhelming, intense anxiety pertaining to vomiting. This specific phobia can also include subcategories of what causes the anxiety, including a fear of vomiting in public, a fear of seeing vomit, a fear of watching the action of vomiting or fear of being nauseated. It is common for emetophobics to be underweight, or even anorexic, due to strict diets and restrictions they make for themselves. The thought of someone possibly vomiting can cause the phobic person to engage in extreme behaviors to escape the perceived threat of that particular situation, in which the phobic person will go to great lengths to avoid even potential situations that could even be perceived as "threatening".
Death anxiety is anxiety caused by thoughts of death. One source defines death anxiety as a "feeling of dread, apprehension or solicitude (anxiety) when one thinks of the process of dying, or ceasing to 'be'".

Cynophobia is the fear of dogs. Cynophobia is classified as a specific phobia, under the subtype "animal phobias". According to Dr. Timothy O. Rentz of the Laboratory for the Study of Anxiety Disorders at the University of Texas, animal phobias are among the most common of the specific phobias and 36% of patients who seek treatment report being afraid of dogs or cats. Although snakes and spiders are more common animal phobias, cynophobia is especially debilitating because of the high prevalence of dogs and the general ignorance of dog owners to the phobia. The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) reports that only 12% to 30% of those suffering from a specific phobia will seek treatment.
