Decision-making and prepotent response inhibition functions in excessive internet users

Area of Science:

• Neuroscience
• Psychology
• Behavioral Science

Background:

• Excessive Internet use (EIU) is a growing global concern, often viewed as a behavioral addiction.
• Limited experimental data exists on the cognitive functions of individuals with EIU, particularly in comparison to other addictive behaviors.
• Understanding cognitive differences in EIUers is crucial for developing targeted interventions.

Purpose of the Study:

• To investigate decision-making and response inhibition in individuals with Excessive Internet use (EIU).
• To compare cognitive functions between EIUers and a control group.
• To explore the relationship between EIU and other addictive behaviors.

Main Methods:

• Employed a Gambling Task to assess decision-making.
• Utilized a Go/no-go Task to evaluate prepotent response inhibition.
• Compared performance on these tasks between a group of EIUers and a control group.

Main Results:

• EIUers demonstrated deficits in decision-making, evidenced by slower strategy learning in the Gambling Task.
• EIUers exhibited significantly higher accuracy in the no-go condition of the Go/no-go Task compared to controls.
• Findings suggest a potential dissociation between decision-making and response inhibition mechanisms in EIU.

Conclusions:

• EIU shares some cognitive similarities with other addictive behaviors like drug abuse and pathological gambling, particularly in decision-making deficits.
• EIUers show a lag in strategy learning rather than an inability to learn from consequences.
• Despite better performance on specific inhibition tasks, EIUers struggle with real-world impulse control, warranting further investigation into their inhibitory capacities.
