Reset a task set after five minutes of mindfulness practice

Area of Science:

• Cognitive Psychology
• Neuroscience
• Mindfulness Research

Background:

• Task sets can create persistent cognitive interference, known as carryover effects.
• Understanding how to mitigate these effects is crucial for optimizing cognitive performance.

Purpose of the Study:

• To evaluate the efficacy of brief mindfulness practice in reducing carryover effects.
• To investigate the underlying mechanisms of mindfulness in resetting task-specific attentional control.

Main Methods:

• Experiment 1: Assessed color interference in visual search based on target relevance.
• Experiment 2: Compared mindfulness, scene-viewing, and distraction interventions on carryover effects.
• Experiment 3: Examined attentional control modes following interventions using a letter judgment task.

Main Results:

• Color carryover effects were observed when color was a defining search feature.
• Only mindfulness practice significantly reduced the carryover effect between task blocks.
• Mindfulness participants reconfigured attentional control, while scene-viewing participants maintained suppressive control.

Conclusions:

• Brief mindfulness practice is effective in mitigating cognitive carryover effects.
• Mindfulness resets task sets by reconfiguring attentional control modes.
• This suggests mindfulness enhances focus by promoting present-moment awareness.
