  4. Agoraphobia
  5. Generalized Anxiety Disorder (GAD)

3.4 Phobia

Meaning

A phobia is:

An intense, irrational, and persistent fear of a particular object, situation, or activity.

The fear is:

  • Out of proportion to actual danger
  • Difficult to control

3.5 Specific Phobias

Specific phobia involves fear of a particular object or situation.


Common Types of Specific Phobia

TypeExample
Animal TypeDogs, snakes, spiders
Natural EnvironmentStorms, heights, water
Blood-Injection-InjuryNeedles, blood
Situational TypeElevators, airplanes
OtherChoking, loud sounds

Clinical Picture of Specific Phobia

A person may experience:

  • Extreme fear
  • Panic attacks
  • Avoidance
  • Sweating
  • Trembling
  • Increased heartbeat

Even thinking about the feared object may create anxiety.


Example

A person afraid of elevators may:

  • Use stairs even for 20 floors.

Dynamics of Specific Phobia

“Dynamics” means causes and underlying mechanisms.


Causes of Specific Phobia


1. Classical Conditioning

Developed by:
Ivan Pavlov

Fear develops after traumatic experiences.

Example:

  • Dog bite → lifelong dog phobia

2. Observational Learning

Developed by:
Albert Bandura

Fear can be learned by observing others.

Example:

  • Child sees mother fear snakes → develops snake phobia

3. Evolutionary Factors

Humans are biologically prepared to fear dangerous things.

Examples:

  • Snakes
  • Heights
  • Darkness

Because these threatened survival historically.

Emotional Features

  • Embarrassment
  • Shame
  • Helplessness

Cognitive Features

People may think:

  • “I will die.”
  • “I will lose control.”
  • “Something terrible will happen.”

3.7 Dynamics of Specific Phobia

Specific phobia continues because of:

Avoidance Reinforcement

Avoiding feared objects reduces anxiety temporarily.

This relief reinforces avoidance.

Thus:
Fear never decreases naturally.


Example

A person avoiding airplanes:

  • Never learns flying is safe.

So fear continues.

BiologicalPsychologicalSocial
