Attentional scope is reduced by Internet use: A behavior and ERP study

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• The Internet, a pervasive environment, significantly influences human cognition.
• Online information is often fragmented and concrete, contrasting with integrative knowledge.
• Construal Level Theory suggests processing concrete information reduces attentional scope.

Purpose of the Study:

• To investigate the impact of Internet use on attentional scope.
• To test the hypothesis that processing fragmented online information narrows attention.
• To examine both behavioral and neural correlates of this cognitive change.

Main Methods:

• Two experiments were conducted involving online shopping, reading, or resting.
• A divided attention Navon-letter task measured attentional scope.
• Electroencephalography (EEG) and event-related potentials (ERPs) recorded neural activity.

Main Results:

• Internet use, unlike reading or resting, significantly decreased attentional scope.
• Neural data revealed reduced lower-alpha activity during Internet use.
• Post-activity EEG/ERP analysis showed a distinct neural response pattern in the Internet group.

Conclusions:

• Surfing the Internet demonstrably reduces attentional scope.
• This effect is linked to processing concrete, fragmentary information online.
• The observed reduction in attentional scope may have lasting cognitive implications.
