Products With High Purchase Frequency Require Greater Inhibitory Control: An Event-Related Potential Study.

Area of Science:

• Cognitive Neuroscience
• Consumer Psychology
• Neuroeconomics

Background:

• Past behavior significantly influences present actions, particularly in response inhibition tasks.
• Previous research focused on immediate action history, neglecting longer-term behavioral influences.

Purpose of the Study:

• To investigate the long-term effects of habitual consumer behavior on response inhibition.
• To examine how frequent product choices in daily life impact neural activity during inhibitory control tasks.

Main Methods:

• Utilized event-related potentials (ERPs) during a Go/No-go task.
• Assigned product stimuli based on participants' self-reported purchase and usage frequency.
• Analyzed the No-go-N2 component amplitude and latency.

Main Results:

• Frequently purchased No-go stimuli elicited a larger No-go-N2 component amplitude.
• A negative shift in brain activity was observed between 200-300ms for high-frequency stimuli.
• This suggests stronger inhibition conflicts and increased cognitive control demands.

Conclusions:

• Repetitive consumer behavior establishes a response history with lasting effects on behavior.
• Habitual choices influence the inhibition of simple motor responses, like button pressing.
• Daily life behaviors shape cognitive control mechanisms.
