Table 2.
Experiment 1: percentage coverage, amount of systematic viewing, total viewing time and diagnostic performance by expertise level
| Expertise level | N | Percentage coverage | Levenshtein distance | Total viewing time (s) | Diagnostic performance (% correct) | ||||
|---|---|---|---|---|---|---|---|---|---|
| M (%) | SD (%) | M | SD | M | SD | M | SD | ||
| Students | 11 | 62.9 | 9.5 | .89 | .02 | 39.5 | 14.5 | 74.6 | 18.1 |
| Residents | 10 | 57.5 | 9.7 | .88 | .04 | 27.7 | 11.6 | 85.5 | 13.8 |
| Radiologists | 9 | 49.6 | 11.6 | .85 | .05 | 18.4 | 6.7 | 91.1 | 14.5 |
The amount of systematic viewing is quantified using the Levenshtein distance, a higher Levenshtein distance indicates less systematic viewing
