- Population
- Adults
- Protocol
- video observation of clinical EEG reading; Vividness of Visual Imagery Questionnaire
Key findings
- 3 of 5 readers used a fast holistic style; 2 used a slower detail-focused style
- Detail readers spent about 8.5 s per page versus about 2.3 s for holistic readers
- Detail readers took more notes, made more measurements and flipped back more often
- Holistic reading was linked to more vivid visual imagery scores
Five experienced neurologists were filmed by an overhead camera while reading routine paper EEG records, and they also completed a questionnaire on how vividly they form mental images. Two reading styles emerged: a fast holistic style with few notes and little flipping back, and a slow detailed style with more notes, measurements and back-and-forth page checking. The holistic readers tended to score higher on visual imagery, though the sample was very small and diagnostic accuracy was not checked.
