Verified step by step guidance

1. Step 1: Begin by understanding the concept of 'diathesis.' In psychology, diathesis refers to a predisposition or vulnerability to developing a psychological disorder. This predisposition can be biological, psychological, or environmental.
2. Step 2: Analyze each option provided in the question to determine if it fits the definition of diathesis. For example, particular thought patterns (e.g., fixations on negative events) represent a psychological predisposition, which aligns with the concept of diathesis.
3. Step 3: Evaluate adverse childhood experiences. These are environmental factors that can create vulnerabilities or predispositions to psychological disorders, making them an example of diathesis.
4. Step 4: Assess heightened activation of particular brain regions. This represents a biological predisposition, as certain brain regions may be more active in individuals predisposed to certain psychological conditions, fitting the definition of diathesis.
5. Step 5: Conclude that all three options (I, II, and III) are examples of diathesis, as they each represent a form of vulnerability—psychological, environmental, or biological—that can contribute to the development of psychological disorders.
