Definitions of Abnormality and Mental Health Disorders

This section explores various approaches to defining abnormal psychology and mental health disorders:

1. Statistical Infrequency: Behaviors that are extremely rare are considered abnormal.

Example: Rating fear of dogs on a scale of 1-10, with normal results expected around 4-6. Any results outside this range would be seen as abnormal.

2. Deviation from Social Norms: Behavior that doesn't conform to societal standards is considered abnormal.

Highlight: This definition is subject to cultural relativism, as social norms vary across cultures and time periods.

3. Failure to Function Adequately: Inability to perform daily life tasks and meet societal expectations.

Vocabulary: The WHODAS (World Health Organization Disability Assessment Schedule) considers six areas needed for adequate functioning.

4. Deviation from Ideal Mental Health (Jahoda, 1958): Absence of characteristics that enable an individual to feel happy and function well.

Definition: Jahoda's model includes six categories: self-attitudes, personal growth, self-actualization, integration, autonomy, accurate perception of reality, and mastery of the environment.

The document also briefly touches on specific mental health conditions:

• Phobias: Classified as anxiety disorders, characterized by irrational fears and avoidance behaviors.

• Depression: Categorized as a mood disorder, with potential genetic factors influencing serotonin levels.

Highlight: The cognitive theory of phobias emphasizes the role of irrational beliefs and thought patterns in maintaining phobic responses.

Evaluations of these definitions highlight their strengths and limitations:

• Statistical infrequency: The cut-off point for abnormality is subjective.
• Social norms: Subject to cultural relativism and historical changes.
• Failure to function: Judgments of adequate functioning can be subjective and culturally biased.
• Ideal mental health: Criteria may be unrealistic, and not all abnormal behaviors are undesirable.

Quote: "Evaluation: Criteria is unrealistic - almost no one reaches all the criteria, therefore the majority of people would be seen as abnormal."

These definitions and theories provide a comprehensive framework for understanding mental health disorders and abnormal psychology, emphasizing the complexity of categorizing and treating psychological conditions.

Systematic Desensitization and Phobia Treatment

Systematic desensitization is a therapeutic technique used to treat phobias through a process of gradual exposure and relaxation. This method involves three key steps:

1. Relaxation training: The patient learns deep breathing and muscle relaxation techniques.

2. Creating a fear hierarchy: The therapist and patient develop a ranked list of feared situations, from least to most anxiety-provoking.

3. Gradual exposure: The patient works through the hierarchy while practicing relaxation, eventually mastering the feared situation.

Definition: Systematic desensitization is a form of counterconditioning, where a new, calming association is taught to replace the original fear response.

Highlight: Studies show that systematic desensitization is successful for about 75% of patients with phobias.

The effectiveness of systematic desensitization has been demonstrated for various phobias. However, it may not work for all fears, especially those with deep evolutionary roots.

Example: For acrophobia (fear of heights), the steps might include looking at pictures of tall buildings, standing on a low balcony, and gradually increasing height exposure.

Other cognitive-behavioral approaches to treating phobias are also discussed:

• Ellis' ABC Model: Examining the Activating event, Beliefs, and Consequences of phobic reactions.
• Flooding: A more intense exposure therapy where the patient faces their fear directly.
• Beck's Negative Triad: Addressing irrational and negative beliefs that contribute to phobias.

Vocabulary: Counterconditioning refers to the process of replacing an undesirable response to a stimulus with a more desirable one.

The document also explores various theories explaining the development of phobias:

1. Classical conditioning: Phobias are acquired through association with a traumatic event.

Example: A dog bite (unconditioned stimulus) creates fear (unconditioned response). The dog (neutral stimulus) becomes associated with fear, becoming a conditioned stimulus that produces a fear response.

2. Operant conditioning: Phobic behaviors are reinforced through avoidance.

3. Social Learning Theory: Phobias may be learned by observing others' fearful responses.

Quote: "Support for social learning - Bandura and Rosenthal did an experiment where a model acted as if he was in pain every time a buzzer sounded. Participants who had observed this also showed an emotional reaction to the buzzer."

These theories form part of the Two-process model of phobias, which combines classical and operant conditioning to explain phobia acquisition and maintenance.
