Internet-word compared with daily-word priming reduces attentional scope

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• Visual attentional scope, a key aspect of cognitive processing, influences how individuals perceive global versus local information.
• The increasing prevalence of internet usage raises questions about its impact on cognitive functions like attention.

Purpose of the Study:

• To investigate whether the internet environment leads to a narrower visual attentional scope compared to a daily-life environment.
• To examine the effects of internet-related versus daily-life-related word priming on attentional scope.

Main Methods:

• Participants completed a Navon letter task after being primed with either internet-related or daily-life-related words.
• Experiment 1 measured reaction times to assess global versus local processing priority.
• Experiment 2 utilized electroencephalography (EEG) to analyze event-related potentials (ERPs), specifically P2 and N2 amplitudes.

Main Results:

• Reaction times in Experiment 1 indicated a greater global processing priority following daily-life word priming compared to internet word priming.
• EEG data in Experiment 2 revealed distinct N2 amplitude patterns between conditions, suggesting differences in cognitive control related to attentional scope.
• Priming with internet-related words resulted in a narrower attentional scope.

Conclusions:

• The findings suggest that the internet environment is associated with a narrower visual attentional scope.
• Cognitive control mechanisms may be influenced by the type of priming, affecting the ability to manage attentional focus.
• This research highlights potential cognitive consequences of prolonged internet use.
