Mind wandering in text comprehension under dual-task conditions.

Area of Science:

• Cognitive Psychology
• Reading Comprehension
• Attention and Memory

Background:

• Dual-task conditions often impair performance on primary tasks.
• The missing-letter effect demonstrates attentional focus during reading.
• Mind wandering negatively impacts reading comprehension.

Purpose of the Study:

• To investigate the impact of dual-task reading on comprehension.
• To examine the relationship between on-task probes, working memory, and comprehension.
• To explore how attentional focus affects recognition versus recall.

Main Methods:

• Two experiments involving reading under dual-task conditions (monitoring for the letter 'e').
• Comprehension assessed via recognition tests (Experiment 1) and recall (Experiment 2).
• Comparison of dual-task performance with single-task control conditions.

Main Results:

• The missing-letter effect was replicated, with 'e' detection impaired in function words.
• On-task probes were detected more effectively when subjects were focused.
• Reading comprehension was better in single-task conditions.
• Dual-task comprehension showed an on-task effect for recall but not recognition.

Conclusions:

• On-task probe responses may rely on retrospective working memory assessment.
• Dual-task conditions may decouple working memory contents from reading processes needed for recognition.
• Findings have implications for models of text comprehension and interpreting on-task probe data.
