Fear of Monsters
Teratophobia
Teratophobia is glossed on phobia lists as fear of monsters, and the printed encyclopedia that carries it defines something else: fear of deformed people, or of bearing a monster. Both readings are defensible from the Greek and only one of them describes anything a clinician has written up. The other describes a developmental stage that most children leave behind on their own.
What the reference work says about teratophobia
Ronald Doctor, Ada Kahn and Christine Adamec define teratophobia in the 2008 third edition of their encyclopedia of phobias as fear of deformed people or of bearing a monster, and cross-reference it to two entries of its own components. They add two sentences about who has it. Some women develop the fear while pregnant. Others fear becoming pregnant because of it.
That second sentence is the reason the term is worth a page. Most specific phobias cost their owner an activity: a flight not taken, a lift not entered. This one, in the form the encyclopedia records, can cost a person a child, and it does so on the strength of a fear about what the child might turn out to be rather than about anything that has happened.
Why the monster under the bed is different
The fear of monsters that the lists mean is studied, and it is not studied as a phobia. Susan Marakovitz, Robert Wagmiller, Nicholas Mian, Margaret Briggs-Gowan and Alice Carter surveyed 1,202 mothers of two- and three-year-olds for a paper published in the Journal of Clinical Child and Adolescent Psychology in 2011, and their opening line puts fear of monsters under the bed alongside sadness at a lost toy as feelings that are usually normative and transient, resolved by the child's own developing self-regulation or by a parent.
Their subject was the minority of cases where it is not that. What they found associated with anxiety and depression problems in children this young:
- child temperament
- maternal affective symptoms
- family expressiveness
- exposure to violence, which was associated with anxiety alone Where maternal affective symptoms were high, inhibited girls were rated as more anxious and inhibited boys were not.
Nothing in that paper uses the word teratophobia. A child's fear of monsters is an age, and the terminology that would make it a disorder is not applied to it.
What the Greek teras originally meant
The Greek teras named a sign sent by the gods, an event read as a warning, and only afterwards the malformed creature that might constitute one. Teratology carries the older sense into current medicine as the study of developmental abnormality, which is why a teratogen is a substance that causes birth defects rather than one that produces monsters. The encyclopedia's definition sits closer to that root than the list sites' does.
Why the phobia lists copy each other
Wikipedia's list of phobias says so directly: many such lists circulate with words collected indiscriminately from sources that copy one another, and a number of sites generate a page for any phobia name by dropping it into a standard template, a practice it names as content spamming aimed at search engines. The example it gives of where that ends is a page offering to cure prostitute phobia.
The complaint is not new. The American Journal of Psychology printed one in the year 1897 about the absurd tendency to give Greek names to objects feared, and offered klopsophobia, fear of thieves, as a specimen of where the habit leads. Teratophobia is older and better attested than that, and it still arrives at a reader attached to the wrong definition most of the time.
What is missing from the accounts
Neither definition has a rate attached. No survey has asked how many people fear deformed people, and none has asked how many avoid pregnancy for the reason the encyclopedia gives, which would be the more useful of the two figures because it names a consequence. The 2008 entry runs to four sentences and the 2011 paper never uses the word, so the term sits between a reference work that describes it without measuring it and a literature that measures the neighbouring thing without naming it.
Told apart
Often confused with Fear of Monsters
- Fear of ChildbirthInjury to the baby is named among tokophobia's component fears, and both can end in a decision not to become pregnant at all. Tokophobia fears the process; this fears the result.
- Fear of Body DeformityBody dysmorphic disorder concerns the person's own appearance. This concerns other people's, or an unborn child's, and nothing about the person holding it.
- Fear of UglinessCacophobia and teratophobia are named as neighbours in discussions of aversion to disfigurement, and the boundary between disliking a face and fearing one is not drawn anywhere in the reference literature.
Common questions
Questions about Teratophobia
- Does the word mean fear of monsters or not?
- It depends entirely on which source is asked. The encyclopedia of phobias that carries it defines fear of deformed people or of bearing a monster. Online phobia lists gloss it as fear of monsters and leave the rest out. Both readings work from the Greek teras, and only the first one has anything written about it.
- Is a child's fear of monsters a phobia?
- Not as the research literature treats it. Susan Marakovitz and colleagues, surveying 1,202 mothers of two- and three-year-olds in 2011, describe fear of monsters under the bed as ordinarily a normative and transient feeling that resolves through the child's own self-regulation or a parent's help. Their paper is about the minority in whom early anxiety persists, and it does not reach for a Greek name.
- How can a fear cost someone a child?
- The encyclopedia records that some women avoid becoming pregnant because of the fear of bearing a deformed child. The avoidance a specific phobia usually produces is a route not driven or a room not entered. This one is a decision that does not reverse.
- What did teras mean before it meant monster?
- A sign or portent sent by the gods. Medicine kept the older sense: teratology is the study of developmental abnormality and a teratogen is a substance that causes birth defects.
- Why do so many phobia lists carry words nobody uses?
- Wikipedia's own list explains it. Lists copy each other, and some sites generate a page for any name by pouring it into a fixed template, which it calls content spamming and illustrates with an offer to cure prostitute phobia. The American Journal of Psychology was complaining about the same habit in 1897.
