Incongruency sequence effects reduce taboo interference in picture naming

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Neuroscience

Background:

• Taboo interference is a well-documented phenomenon in speech production.
• Sequence effects, or trial-to-trial facilitation, can influence cognitive processes.
• Attentional control plays a crucial role in managing interference during cognitive tasks.

Purpose of the Study:

• To investigate if sequence effects reduce taboo interference during picture naming.
• To examine the role of attentional control in modulating taboo interference.
• To explore the impact of preceding trial congruency and emotional valence on taboo interference.

Main Methods:

• Participants performed a picture naming task with congruent or incongruent distractor words.
• Distractor words varied in emotional valence (taboo or neutral).
• Sequence effects were analyzed by comparing naming times based on the preceding trial's characteristics.

Main Results:

• Taboo interference was reduced when incongruent-taboo trials followed incongruent-neutral trials, compared to congruent-neutral trials.
• Naming times for incongruent-taboo trials did not differ based on the emotional valence of the preceding incongruent trial.
• These findings suggest that attentional control can mitigate some, but not all, forms of taboo interference related to sequence effects.

Conclusions:

• Sequence effects, modulated by attentional control, can reduce taboo interference in speech production.
• Limitations exist in attentional mechanisms for managing taboo interference, particularly concerning the emotional content of preceding trials.
• The study contributes to understanding attentional control accounts of sequence effects in language production.
