Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is the biological explanation of depression?

    Model answer

    The biological explanation says depression is caused by an imbalance of neurotransmitters in the brain. Low levels of serotonin are especially linked to low mood.

  2. 2

    Why is the biological explanation described as the influence of nature?

    Model answer

    The explanation focuses on brain chemistry, which may be partly inherited. Depression is seen as arising from within the body rather than from experience.

  3. 3

    What is the psychological explanation of depression?

    Model answer

    The psychological explanation says depression is caused by negative ways of thinking. People with depression have negative schemas and attributions.

  4. 4

    What is a negative schema?

    Model answer

    A negative schema is a set of negative beliefs a person holds about themselves, the world and the future. The negative beliefs lead the person to interpret events in a gloomy way.

  5. 5

    How can negative attributions contribute to depression?

    Model answer

    A depressed person tends to blame themselves for failures and see them as permanent. Good events are put down to luck, so they bring no comfort.

  6. 6

    Why is the psychological explanation described as the influence of nurture?

    Model answer

    Negative thinking is thought to be learned through experiences such as criticism or loss. Depression is seen as arising from the environment rather than biology.
