Adults at low reading level are sluggish in disengaging spatial attention

Area of Science:

• Cognitive Psychology
• Neuroscience
• Educational Psychology

Background:

• Attentional shifting is crucial for reading acquisition.
• The precise role of attentional shifting in mature adult reading remains unclear.
• Understanding this relationship is vital for effective reading interventions.

Purpose of the Study:

• To investigate the relationship between attentional shifting and word-reading ability in adult Chinese readers.
• To explore the time course of attentional shifting in relation to reading proficiency.
• To test the phonological mediation hypothesis in adult word reading.

Main Methods:

• Adult readers were grouped by Chinese character reading level.
• The Posner cue-target paradigm with varying stimulus-onset asynchronies (SOAs) was used to assess attentional shifting.
• Phonological processing abilities, including rapid automatic naming and phonological awareness, were measured.

Main Results:

• Adults with lower reading levels exhibited impaired attentional disengagement compared to high-level readers.
• Rapid automatic naming of Chinese characters partially mediated the association between attentional shifting and word reading.
• Evidence supports the phonological mediation hypothesis.

Conclusions:

• Attentional disengagement is a key factor differentiating adult reading levels.
• Phonological processing, particularly rapid automatic naming, plays a mediating role in how attentional shifting influences word reading.
• These findings highlight the importance of attentional and phonological skills in adult reading.
