This study shows that a young woman with delusions was slower to name word colors related to her beliefs. Her attention bias resolved when her delusions subsided, indicating the Stroop paradigm

Area of Science:

  • Cognitive Psychology
  • Clinical Psychology
  • Neuroscience

Background:

  • Delusional beliefs can significantly impact an individual's cognitive processes.
  • Attention bias is a cognitive phenomenon where individuals selectively attend to certain stimuli.
  • Investigating attention bias in specific delusional themes can offer insights into their nature.

Purpose of the Study:

  • To investigate attention bias in a case of delusional disorder using a modified Stroop paradigm.
  • To assess the relationship between delusional content and attentional focus.
  • To monitor changes in attentional bias over time in relation to delusion remission.

Main Methods:

  • A variant of the Stroop paradigm was employed, involving color-naming of words.

Related Experiment Videos

  • Word lists were specifically chosen to relate to the participant's delusional beliefs and associated moods.
  • Performance (color-naming time) was compared between delusion-related and neutral word lists across multiple sessions over two years.

    • Main Results:

    • The participant exhibited significantly slower color-naming times for delusion-related words compared to neutral words.
    • This attention bias was evident during periods when the participant held delusional beliefs.
    • Upon remission of delusions, the slowed response to delusion-related words disappeared.

    Conclusions:

    • The Stroop paradigm is a viable tool for assessing attention bias in individual cases of delusion.
    • Attentional bias is directly linked to the presence and content of delusional beliefs.
    • The Stroop paradigm can be utilized to track the course of attentional bias and delusion remission over time.
