The origin of the centrality deficit in individuals with attention-deficit/hyperactivity disorder

The Task Matters: A Scoping Review on Reading Comprehension Abilities in ADHD

OBJECTIVE

A broad range of tasks have been used to classify individuals with ADHD with reading comprehension difficulties. However, the inconsistency in the literature warrants a scoping review of current knowledge about the relationship between ADHD diagnosis and reading comprehension ability.

METHOD

A comprehensive search strategy was performed to identify relevant articles on the topic. Thirty-four articles met inclusion criteria for the current review.

RESULTS

The evidence as a whole suggests reading comprehension is impaired in ADHD. The most prominent effect was found in studies where participants retell or pick out central ideas in stories. On these tasks, participants with ADHD performed consistently worse than typically developing controls. However, some studies found that performance in ADHD improved when reading comprehension task demands were low.

CONCLUSION

Results suggest that performance in ADHD depends on the way reading comprehension is measured and further guide future work clarifying why there are such discrepant findings across studies.

Pay attention to digital text: The impact of the media on text comprehension and self-monitoring in higher-education students with ADHD

BACKGROUND

Higher-education students with attention deficit hyperactivity disorder (ADHD) often face difficulties in self-regulation of learning (SRL). Studies of typical students have shown that SRL is less effective for digitally displayed texts. The current study investigated the influence of the media (digital, print) on reading comprehension and self-monitoring (a component of SRL) in higher-education students with and without ADHD.

METHODS

Forty-five students with ADHD and 61 matched controls read an expository text displayed digitally or in print. Then, they predicted their performance score and answered comprehension questions. Sustained attention and set-shifting abilities were also assessed.

RESULTS

In the digital condition, students with ADHD had significantly lower comprehension scores and were overconfident in their predictions of success relative to controls. In the print condition, the ADHD group spent more time reading the text, but their predictions of performance and comprehension scores were comparable to those of the control group. Poor sustained attention was significantly correlated with lower comprehension scores in both media conditions, whereas set-shifting correlated only with comprehension of the printed text.

CONCLUSIONS

Understanding a digitally displayed text is more challenging for students with ADHD than their peers, particularly when the conditions of the comprehension task favor good SRL skills.
