Involuntary symbol manipulation (Pig Latin) from external control: Implications for thought suppression

Area of Science:

• Cognitive Psychology
• Neuroscience

Background:

• Ironic processing describes the phenomenon where attempting to suppress a thought increases its accessibility.
• The Reflexive Imagery Task (RIT) demonstrates involuntary conscious content generation following action set activation.
• Prior research suggested the RIT effect might be limited to automatic processes.

Purpose of the Study:

• To investigate whether the RIT effect extends to complex cognitive processes, specifically symbol manipulation.
• To challenge the criticism that the RIT is only applicable to automatic memory retrieval.

Main Methods:

• Participants were trained on a complex word-manipulation task (e.g., Pig Latin).
• Following training, participants performed the RIT, being instructed *not* to perform the trained word transformations on stimulus words.
• This tested whether involuntary thought intrusion occurs during complex, non-automatic cognitive tasks.

Main Results:

• The RIT effect was observed even when participants were instructed not to engage in the complex symbol manipulation task.
• This indicates that involuntary conscious content can arise even during effortful, controlled cognitive processes.
• The findings suggest the encapsulated nature of conscious content generation.

Conclusions:

• The RIT effect is not limited to automatic processes and applies to complex cognitive tasks.
• This has significant implications for understanding cognitive control and the nature of conscious and unconscious processing.
• The findings may also inform theories related to psychopathology.
