    • Definition: A tendency to provide excessive detail and digress from the main topic.
    • Example: Client begins discussing childhood memories when asked about sleep habits but does not return to sleep habits.

  • Tangential Thinking

    • Definition: When an individual fails to provide the information necessary to answer a question directly; there is a shift away from the main topic.
    • Example: A client stops mid-sentence and stares into space before changing the topic.
    • Key Point: A nurse observes this behavior and identifies it as tangential thinking.

  • Thought Blocking

    • Definition: An abrupt interruption in speech, suggesting a loss of thought.
    • Example: The client suddenly stops mid-sentence and stares blankly for several seconds.

  • Thought Insertion

    • Definition: The belief that external forces are putting thoughts into one’s mind.
    • Example: A client murmurs that others can hear what they think; indicates that they’re experiencing thought broadcasting.

  • Thought Broadcasting
