Individuals with Internet addiction disorder (IAD) and pathological gambling (PG) exhibit impaired working memory, executive function, and increased impulsivity. Notably, IAD patients demonstrate higher impulsivity than PG patients.
Area of Science:
- Neuroscience
- Psychology
- Behavioral Science
Background:
- Internet addiction disorder (IAD) and pathological gambling (PG) are recognized behavioral addictions.
- Both conditions are associated with significant cognitive and emotional dysregulation.
- Understanding shared and distinct cognitive deficits is crucial for targeted interventions.
Purpose of the Study:
- To investigate cognitive similarities and differences between individuals with IAD and PG.
- To compare working memory, executive function, and impulsivity in IAD, PG, and control groups.
- To determine if IAD patients exhibit greater impulsivity than PG patients.
Main Methods:
- A comparative study involving 23 individuals with IAD, 23 with PG, and 23 healthy controls.
- Cognitive assessments included the digit span task, Wisconsin Card Sorting Test, go/no-go task, and Barratt Impulsiveness Scale-11 (BIS-11).
- Standardized experimental conditions were maintained for all participants.
Main Results:
- Both IAD and PG groups showed significantly higher error rates (false alarms, total errors, perseverative errors) and BIS-11 scores compared to controls.
- IAD and PG groups exhibited significantly lower performance in working memory tasks (digit span forward/backward, conceptual level responses, categories completed) and hit rates.
- The IAD group displayed higher false alarm rates and BIS-11 scores, and a lower hit rate compared to the PG group.
Conclusions:
- Individuals with IAD and PG share deficits in working memory, executive function, and impulsivity.
- IAD is associated with a greater degree of impulsivity compared to PG.
- These findings highlight overlapping and distinct neurocognitive profiles in behavioral addictions.
