**Core Concept**
The cognitive model of depression is a psychological theory that attributes the development and maintenance of depressive symptoms to negative thought patterns and cognitive distortions. This model posits that individuals with depression have a biased and distorted way of thinking, which contributes to their emotional and behavioral symptoms.

**Why the Correct Answer is Right**
Aaron Beck's cognitive model of depression, also known as cognitive-behavioral theory, proposes that individuals with depression have a negative cognitive triad, consisting of negative views of themselves, the world, and their future. This negative thinking pattern is thought to be perpetuated by cognitive distortions, such as all-or-nothing thinking, overgeneralization, and catastrophizing. The cognitive model emphasizes the role of these negative thought patterns in the development and maintenance of depressive symptoms.

**Why Each Wrong Option is Incorrect**
**Option A:** Albert Ellis's rational emotive behavior therapy (REBT) is another cognitive-behavioral approach, but it is not specifically focused on depression. While Ellis's theory does address irrational thinking, it is broader in scope than Beck's cognitive model.
**Option C:** There is no prominent figure in psychology or psychiatry by the name of Godfrey associated with a cognitive model of depression. It is possible that this option is a distractor or a fictional name.
**Option D:** Meichenbaum is a psychologist who developed self-instructional training, a cognitive-behavioral technique, but he is not associated with a cognitive model of depression.

**Clinical Pearl / High-Yield Fact**
Beck's cognitive model of depression highlights the importance of identifying and challenging negative thought patterns in the treatment of depression. This approach has been shown to be effective in reducing depressive symptoms and improving quality of life.
