Factors Affecting Dwell Times in Visual Search
Author Information

Hypothesis
Are dwell times in visual search tasks determined more by similarity to the target or by perceptual difficulty?
Conclusion
Dwell times are primarily determined by target similarity rather than perceptual difficulty.
Supporting Evidence
- Dwell times were longer for distractors with the same line-width as the target.
- Dwell times did not appear to be affected by line thickness per se.
- Participants provided informed consent and the study was ethically approved.
Takeaway
When looking for something, we spend more time looking at things that look like what we're searching for, rather than things that are just hard to see.
Methodology
The study involved a visual search task with varying line-width distractors to measure dwell times.
Limitations
The study's findings may not apply to stimuli below the detection threshold.
Participant Demographics
12 students (5 male, 7 female, mean age: 28.5) from The University of Queensland.
