Characteristics of Depression

Emotional, Behavioral, and Cognitive symptoms including persistent low mood, reduced activity levels, and poor concentration.

Negative Triad

Beck's theory identifying a negative view of self, the world, and the future as key components in depression.

Cognitive Behavioral Therapy (CBT)

A treatment that challenges negative thoughts and replaces them with rational beliefs; includes cognitive restructuring and behavioral activation.

SSRIs

Selective Serotonin Reuptake Inhibitors, a type of drug therapy that increases serotonin levels in the brain to treat depression.

Beck's Theory

A cognitive explanation of depression that suggests it arises from faulty thinking patterns and negative schemas.

Operant Conditioning

A learning process where behaviors are repeated due to the consequences they produce, often seen in compulsions associated with OCD.

Negative Reinforcement

The reinforcement of a behavior by the removal of an aversive stimulus, leading to increased frequency of that behavior.

Exposure and Response Prevention (ERP)

A treatment for OCD where the patient is exposed to anxiety triggers and prevented from performing compulsions to reduce anxiety through habituation.

Neurochemistry

The study of chemical processes in the brain, particularly regarding neurotransmitters like serotonin's link to mood regulation.

Cognitive Explanation of OCD

Focuses on the role of thought patterns and beliefs, highlighting how obsessions and recognitions of irrationality contribute to OCD.

Concordance Rate

The likelihood that both twins share a trait; in depression, the concordance rate for identical twins is around 40%.

Classical Conditioning

A learning process where a neutral stimulus becomes associated with anxiety, contributing to the development of compulsions in OCD.
