Attention Fatigue, Attention Restoration
Conditions
Brief summary
The purpose of this research study is to find out about how looking at different types of pictures can affect people's attention spans. Attention Restoration Theory (ART) suggests that there are two types of attention. One type (directed attention) can become tired and cause people to make mistakes. The other type (involuntary attention) gives directed attention a chance to rest, so people make less mistakes. Certain types of pictures are good at capturing involuntary attention. We think that capturing involuntary attention will help emergency physicians make less mistakes on tests of attention. This study will allow us to learn more about it.
Detailed description
In this study, participants will be asked to do the following things: 1. Before their usual shift in the emergency department, arrive ten minutes early to rate their mood and complete a Digit Span Backwards (DSB) task that tests their memory of different sets of numbers. 2. Five hours into their shift, they will take a ten minute break. 3. During this break, they will be randomly assigned to view either a picture presentation of nature slides or urban slides. 4. After the presentation, they will complete the Digit Span Backwards task again, they will rate their mood again, then return to their shift. Participation in this study will last up to 30 minutes. Approximately fifty individuals will participate in this study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Working memory | 5 hours | Working memory will be assessed using the Digit Span test. Participants are read a sequence of numbers and asked to repeat the same sequence back to the examiner in order (forward span) or in reverse order (backward span). Number of correctly repeated numbers is summed to yield a score ranging from 0 to 28. Higher scores indicated better working memory |
| Positive mood | 5 hours | Positive mood will be assess using the positive affect (PA) scale of the Positive and Negative Affect Schedule (PANAS). The PA scale consists of 10 adjectives which are rated on a 5 point scale from slightly or not at all to extremely. Items are summed to yield a score ranging from 10 to 50 with higher number indicating higher affect. |
| Negative mood | 5 hours | Negative mood will be assess using the negative affect (NA) scale of the PANAS. The NA scale consists of 10 adjectives which are rated on a 5 point scale from slightly or not at all to extremely. Items are summed to yield a score ranging from 10 to 50 with higher number indicating higher affect. |
