Attention switching through text dissimilarity: a cognition research on fragmented reading behavior

Area of Science:

• Cognitive Psychology
• Neuroscience
• Media Studies

Background:

• Fragmented reading is common online.
• This reading style may negatively affect cognitive abilities like attention and memory.
• Understanding attention switching is crucial.

Purpose of the Study:

• To investigate how fragmented reading influences attention switching.
• To determine the relationship between text dissimilarity and cognitive load.
• To explore the impact of fragmented reading on cognitive ability.

Main Methods:

• Collected online news articles (60 sentences, 6 themes).
• Defined text dissimilarity to quantify attention switching.
• Conducted electroencephalography (EEG) experiment measuring P200 responses.

Main Results:

• Lower text dissimilarity correlated with increased working memory capacity.
• Lower text dissimilarity led to reduced working memory load.
• Lower text dissimilarity minimized negative impacts on cognitive ability.

Conclusions:

• Attention switching, driven by conceptual or memory representation differences, is key to fragmented reading's cognitive effects.
• Text dissimilarity offers a new metric for analyzing fragmented reading.
• Findings suggest methods to mitigate negative cognitive impacts on new media platforms.
