Using these three areas can you explain the Using these three areas can you explain the following phobias using each approach: following phobias using each approach:

Fear of a specific object or situation such as: -Fear of a specific object or situation such as: -– Arachnophobia – Fear of spidersArachnophobia – Fear of spiders– Claustrophobia – Fear of enclosed spacesClaustrophobia – Fear of enclosed spaces– Aerophobia – Fear of flyingAerophobia – Fear of flying– Acrophobia – Fear of heightsAcrophobia – Fear of heights– Alektorophobia – Fear of chickensAlektorophobia – Fear of chickens– Androphobia – Fear of menAndrophobia – Fear of men– Carnophobia – Fear of meatCarnophobia – Fear of meat– Emetophobia – Fear of vomitingEmetophobia – Fear of vomiting– Phobophobia – Fear of phobias!Phobophobia – Fear of phobias!

There are 3 learning theories that provide There are 3 learning theories that provide us withus withexplanations for phobias:explanations for phobias:

Watson, J.B., & Rayner, R.

Watson theorised, Watson theorised, emotional responses emotional responses exist in us because we exist in us because we have been conditioned have been conditioned to respond emotionally to respond emotionally to certain stimuli in to certain stimuli in the environment. ( We the environment. ( We learn our emotional learn our emotional reactions).reactions).

Watson believed that Watson believed that all human behavior all human behavior was a product of was a product of learning and learning and conditioning.conditioning.

Most psychologists, as Most psychologists, as well as public opinion well as public opinion in general, were not in general, were not ready to accept these ready to accept these new ideasnew ideas

So Watson set out to So Watson set out to demonstrate that demonstrate that emotions could be emotions could be experimentally experimentally conditionedconditioned

Watson theorised that Watson theorised that if a stimulus that if a stimulus that automatically automatically produces a certain produces a certain emotion in you (such emotion in you (such as fear) is repeatedly as fear) is repeatedly experienced at the experienced at the same moment as same moment as something else, it will something else, it will become associated in become associated in your brain with the your brain with the fearfear

We are not born to We are not born to fear rats, such fears fear rats, such fears are learned through are learned through conditioningconditioning

This formed the This formed the theoretical basis theoretical basis involving a subject involving a subject named “Little Albert”named “Little Albert”

The subject, Albert, was The subject, Albert, was recruited for this study at 9 recruited for this study at 9 monthsmonths

In order to see if Albert was In order to see if Albert was afraid of certain stimuli, he was afraid of certain stimuli, he was presented with a white rat, a presented with a white rat, a rabbit, an other white furry rabbit, an other white furry objects.objects.

At no time did this infant ever At no time did this infant ever show fear in any situation. show fear in any situation.

To determine if a fear reaction To determine if a fear reaction could be produced in Albert, a could be produced in Albert, a steel bar was struck with a steel bar was struck with a hammer behind him. This noise hammer behind him. This noise startled and frightened him and startled and frightened him and made him crymade him cry

Every time the white rat Every time the white rat came near Albert, he came near Albert, he would hear the loud noise would hear the loud noise and it would frighten him. and it would frighten him. This was repeated with This was repeated with other white furry objects other white furry objects (rabbit) This proved that (rabbit) This proved that the emotion of fear could the emotion of fear could be conditionedbe conditioned

After 31 days (rest period), After 31 days (rest period), he was presented again he was presented again with the white rat and was with the white rat and was still very afraid( learned still very afraid( learned emotional response emotional response persisted over time)persisted over time)

Watson’s Fundamental Watson’s Fundamental goals in this experiment:goals in this experiment:

a)a) To demonstrate that the To demonstrate that the Freudian conception of Freudian conception of psychology, that our psychology, that our behavior stems from behavior stems from unconscious processes, unconscious processes, was wrong.was wrong.

b)b) To demonstrate that all To demonstrate that all human behavior stems human behavior stems from learning and from learning and conditioning.conditioning.

This study proved that This study proved that emotional behavior could emotional behavior could be conditioned through be conditioned through simple stimulus response simple stimulus response techniques and also techniques and also launched launched behaviorism behaviorism

Their main point was that Their main point was that they had demonstrated they had demonstrated with little Albert that with little Albert that emotional disturbances in emotional disturbances in adults cannot always be adults cannot always be attributed to sexual attributed to sexual traumas in childhood, as traumas in childhood, as the Freudian view was the Freudian view was commonly interpretedcommonly interpreted

Fear in its extreme Fear in its extreme form, can produce form, can produce serious negative serious negative consequences known consequences known as as phobiasphobias

Many psychologists Many psychologists believed that phobias believed that phobias are conditioned much are conditioned much like Little Albert’s fear like Little Albert’s fear of furry animalsof furry animals
