## Psych of display usage

### Color and phone addiction

Anectodal - switching to a black and white screen reduces addiction of phone as it makes apps less visually appealing (e.g. instagram, tik-tok)

### Negative impact on sleep
There seems to be a clear consensus that using phones/devices before sleep disturbs sleep, particularly in young people. I know there is plenty of discussion around "blue-light" and many products that focus on that aspect specifically. Where I have not (yet) found clear research is in breaking down the different variables and their impact - there is the screen itself, the interaction with digital content (and all the varying content types), etc.

## Psych of interface

Scrolling vs pagination
* [Baker, 2003](https://www.researchgate.net/profile/Barbara-Chaparro/publication/237282327_The_Impact_of_Paging_vs_Scrolling_on_Reading_Online_Text_Passages/links/55e84bad08ae21d099c170ba/The-Impact-of-Paging-vs-Scrolling-on-Reading-Online-Text-Passages.pdf)
    * suggests that scrolling is slower but no difference in reading comprehension vs pagination
* [Sanchez & Wiley, 2009](https://journals.sagepub.com/doi/abs/10.1177/0018720809352788?casa_token=QTYJRhhOBaEAAAAA:RlLGMffalHVty-8VwXPduFDtay4DbNNn9syOkb7qMgk6RUfGJlm3TO1H3fTxOdtT_M7kKhTnQUYF)
    * suggests that scrolling reduced understanding of complex topics, especially in participants with low working memory
* Does scrolling seems to deplete attention and working memory performance more quickly?
