Psychological Case Studies and Diagnostic Criteria for Paper I

Case studies and diagnostic criteria play a crucial role in understanding and diagnosing psychological disorders. For Paper I of UPSC, it is important to focus on specific case studies and diagnostic criteria to gain a comprehensive understanding of various psychological disorders. Here are some key points to consider:

1. Diagnostic and Statistical Manual of Mental Disorders (DSM-5)
The DSM-5 is a widely accepted manual used for diagnosing mental disorders. It provides a comprehensive list of diagnostic criteria for each disorder, enabling clinicians and researchers to identify and classify psychological conditions. It covers a wide range of disorders, including mood disorders, anxiety disorders, personality disorders, etc.

2. Case Study: Phineas Gage
Phineas Gage is a famous case study that demonstrates the impact of brain trauma on personality and behavior. Gage suffered a severe brain injury when a metal rod pierced through his skull, damaging his frontal lobe. This incident dramatically changed his behavior, leading to impulsivity, mood swings, and impaired social functioning.

3. Case Study: Little Albert
Little Albert is another well-known case study conducted by John B. Watson and Rosalie Rayner. The study aimed to demonstrate classical conditioning in a human subject. They conditioned a fear response in a young boy (Albert) by pairing a neutral stimulus (a white rat) with a loud noise. This study highlighted the influence of conditioning on behavior and the development of phobias.

4. Diagnostic Criteria for Major Depressive Disorder

The diagnostic criteria for MDD include the presence of specific symptoms for a minimum duration, such as depressed mood, loss of pleasure, significant weight loss or gain, sleep disturbances, fatigue, difficulty concentrating, and recurrent thoughts of death or suicide.
