Could YOU handle ‘I’m a Celebrity’? Psychologists reveal why so many of us are scared of creepy-crawlies, heights and small spaces
- ‘I’m a Celebrity…Get Me Out of Here!’ has kicked off with Boy George and Chris Moyles in the line-up
- The reality series sees celebrities facing their fears of heights, bugs and small spaces in Bush Tucker Trials
- To celebrate its return to Australia, MailOnline looks at why so many of us share these common phobia
- A fear of heights is thought to be the product of evolution, as it has kept us safe from fatal falls
- An aversion to insects may also have evolved to stop us eating rotting food, where the bugs would be found
It’s the time of year again when many reality TV fans will cosy up every night to watch their favourite celebrities scream on ‘I’m a Celebrity…Get Me Out of Here!’.
This series, Chris Moyles, Boy George and even Matt Hancock are heading into the jungle to face their fears in the infamous Bush Tucker Trials.
Many of these involve being covered in spiders, snakes and cockroaches while trapped in a small box, or jumping out of a helicopter at 10,000 feet.
While different people have different fears, phobias of small spaces, heights and creepy-crawlies are some of the most common.
A fear of heights is thought to come from a survival instinct that has passed down through the generations, but has also been linked to sense of balance.
Meanwhile, a phobia of insects could come from an evolutionary aversion to rotten food or faeces, where creepy crawlies could be found.

A fear of heights, or acrophobia, is one of the most common phobias.
An estimated three to five per cent of the population claim to have it, but about a third say they experience some form of discomfort when up high.
General opinion of how this fear originates has changed over the years from nurture to nature.
It was long assumed to be the result of a traumatic experience, like sustaining an injury through falling.
However, studies have since shown that there isn’t evidence of a connection between acrophobia and experience, suggesting it is an innate fear.
Evolutionary psychologists claim that people with a fear of heights are more likely to remove themselves from the potentially dangerous situation of being up high.
This means that they are more likely to survive that situation, from an evolutionary perspective, and pass on the natural fear to their offspring.

Fear of spiders may be triggered by aversion to scorpions, study says
If you’re terrified of spiders, your fear may actually be rooted in an aversion to scorpions, a new study claims.
In experiments, researchers showed live spiders, scorpions and other arthropods including beetles and crabs to willing participants who rated their emotions.
Participants reacted similarly in terms of fear and disgust to chelicerates – the animal group that includes both spiders and scorpions, the team found.
Only 0.5 per cent of all spider species are potentially dangerous to humans, so it’s thought fear of spiders is based on their similarities to the generally more harmful scorpions.
Scorpions share a similar body plan with spiders, but the former pose more of a threat to humans – they have a powerful venom containing a complex mix of toxins that affect a victim’s nervous system.

Research has also suggested that a fear of heights gets worse as the person gets older, because it is linked to our sense of balance.
Professor Kevin Gournay, from King’s College London, said: ‘As you get older, your organ of balance tends to deteriorate and you’re likely to feel more physically vulnerable.’
Older adults also tend to have people who depend on them, and this can make them more troubled by the possibility of falling.
Another study suggests that acrophobics also perceive heights to be taller than those who do not fear them.
Researchers at California State University San Marcos had participants judge the height of a building when standing at ground level and when atop the building.
Those most afraid of heights judged the building to be about 10 feet (3 meters) higher at ground level than those who were less afraid, and 40 feet (12 meters) taller from the top of the building.
This perception of heights of larger magnitude increases the acrophobic’s perceived risk.
When we see their spindly legs scuttling across the floor, many of us quake with fear.
Although very few spiders in the UK are poisonous, it is estimated that there are around one million arachnophobics in this country.
Psychology professor Jon May said their angular-shaped legs, dark colours and the fact they move unpredictably are all things we are hard-wired to fear.
He explained that studies have shown that people tend to dislike angular shapes and prefer curved ones, have bad associations with dark colours, and prefer creatures we feel we can ‘understand’.
Professor May, from Plymouth University, added: ‘Spiders just tick all these boxes, and like any phobia, when it builds up in someone’s mind they can become scared even seeing a picture.
‘We like bright- coloured butterflies and ladybirds, but spiders are dark coloured with long angular legs – and the shape and colour both have strong negative associations.
‘We are also very sensitive to seeing things moving out of the corner of our eye and immediately notice it, and insects move quickly and unpredictably.
‘People scared of spiders will often report them being bigger than they were or say they saw one crawl into someone’s mouth, which spiders never do. We don’t understand their behaviour.’
Professor May said fear is also ‘socially conditioned’, which means we are more likely to develop it as children if we encounter it at home from our parents or siblings.

HOW MANY OF US HAVE PHOBIAS?
Heights – 3 to 5 percent
Spiders – 3 to 6 per cent
Snakes – 2 to 3 per cent
Insects – 6 per cent
Small spaces – 5 to 10 per cent
Some people aren’t just scared of spiders, but a whole host of creepy-crawlies, including the ‘I’m a Celeb’ favourite of cockroaches.
Some studies suggest that entomophobia is tied to our feeling of disgust and ‘rejection response’ – as in, wanting to get rid of something right away.
Disgust is thought to stem from a desire to keep ourselves safe, like how rotting food will make us ill, so we develop a natural aversion to it.
In the same way, the presence of insects are a sign of something unsafe, like a decaying animal or faeces, and our disgust protects us from that.
A study at the Georgia Institute of Technology imaged participants’ brains while they were shown clips of insects, other dangerous animals and everyday occurrences as a control.
With nearly every participant, the pest videos triggered a reaction in the brain’s insula, a region deep in the cerebral cortex associated with disgust.
The amygdala, a portion of the brain associated with fear, was only triggered by videos of frightening animals.
Dr. Eric Schumacher, one of the researchers, said: ‘Insects in the home produced more disgust in the brain than insects in the wild, especially cockroaches.’
‘Our research suggest that we may be conditioned against pests in the home, because they may be associated with contamination or illness.’
Another idea, proposed by entomologist Dr Jeffery Lockwood, suggests that this particular aversion to insects in the home comes from a sense of invasion.
Dr Adam Hart, an entomologist from the University of Gloucestershire, said that many small children are happy to handle creepy-crawlies in the garden and find them fascinating, but become scared of them as they get older.
He said the rise of ‘nature deficit disorder’ – or children spending more and more time indoors and becoming detached from the natural world – may be increasing our fear of insects.
Small spaces (Claustrophobia)
Claustrophobia is the fear of small spaces, and again, has been the subject of debate as to where it originates.
Like acrophobia, it can also be associated with a traumatic experience, like being trapped in a lift, or even learning it from someone else.
However, many people who have had a stressful experience in a confined space do not develop claustrophobia, suggesting other factors are at play.
Some behavioural psychologists have suggested it is a product of evolution, as tight spaces would produce a threat to survival via suffocation or entrapment.
One study found that people who project their personal space too far beyond their bodies are more likely to experience claustrophobia.
Study participants who had higher levels of claustrophobic underestimated horizontal distances.
Lead author Dr Matthew Longo, from Birkbeck, University of London, said: ‘It makes adaptive sense to be more aware of things that are closer to the body, for both utilitarian purposes and defensive ones.’

A fear of snakes is not thought to be through exposure as it is prevalent in many countries where a snake encounter would be rare.
It is therefore widely accepted to be evolutionary, and instilled within people after their fearful ancestors successfully avoided the poisonous reptile, and were able to reproduce as a result.
A 2017 study from the Max Planck Institute for Human Cognitive and Brain Sciences in Germany found that images of snakes evoked a stress reaction in infants of just six months old.
Lead author Dr Stefanie Hoehl said: ‘When we showed pictures of a snake or a spider to the babies instead of a flower or a fish of the same size and colour, they reacted with significantly bigger pupils.
‘In constant light conditions this change in size of the pupils is an important signal for the activation of the noradrenergic system in the brain, which is responsible for stress reactions.
‘This obviously inherited stress reaction in turn predisposes us to learn these animals as dangerous or disgusting.
‘When this accompanies further factors it can develop into a real fear or even phobia.’
The researchers say that other studies show a similar reaction isn’t elicited from pictures of other theoretically dangerous animals, like bears and rhinos.
‘We assume that the reason for this particular reaction upon seeing spiders and snakes is due to the coexistence of these potentially dangerous animals with humans and their ancestors for more than 40 to 60 million years—and therefore much longer than with today’s dangerous mammals,’ added Dr Hoehl.
‘The reaction which is induced by animal groups feared from birth could have been embedded in the brain for an evolutionarily long time.’
Anthropologists have also suggested that the need to spot snakes in the wild may have led early primates to develop better vision and larger brains.
