Taboo words capture attention and improve memory recall more than neutral words. Non-taboo negative words enhance memory, especially in mixed lists, supporting multifactor theories of emotion

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Linguistics

Background:

  • Emotional stimuli often capture attention and are better remembered than neutral stimuli.
  • Theories of emotion's effects on cognition propose multiple mechanisms, including attention, elaboration, and distinctiveness.

Purpose of the Study:

  • To investigate the differential effects of taboo, non-taboo negative, and neutral words on attention and memory.
  • To compare these effects across different experimental designs (within-subjects, between-subjects, mixed-list).
  • To test predictions derived from multifactor theories of emotion's influence on cognitive processes.

Main Methods:

  • Participants performed a color-naming task (measuring attention) followed by incidental free recall (measuring memory).
  • Three word categories were used: taboo, non-taboo negative-affect, and neutral.

Related Experiment Videos

  • Experiments employed within-subjects, between-subjects, and mixed-list designs with varying stimulus presentation (blocked vs. random) and interstimulus intervals (ISIs).

    • Main Results:

    • Taboo words consistently led to slower color-naming times and enhanced memory recall compared to neutral words.
    • Non-taboo negative words showed slower color naming only under blocked presentation and short ISIs.
    • Non-taboo negative words were better remembered than neutral words in mixed-list designs, regardless of presentation or ISI.

    Conclusions:

    • Emotional intensity and threat level modulate attention and memory differently.
    • Threatening stimuli (taboo words) benefit from increased attention, elaboration, and distinctiveness.
    • Non-threatening emotional stimuli (non-taboo negative words) primarily benefit from increased item distinctiveness.
