Effectively directing your smartphone use?
Together with great @lorenz_spreen & @frederikRiedel, we tested @one_sec_app's effectiveness to help control your app consumption, now published in @PNASNews!
For a quick guide through the paper see @lorenz_spreen's thread summary:
Very happy to share our latest work published today in @PNASNews!
Led by @GruningJ and working with @frederikRiedel, we tested how the self-nudging app @one_sec_app changes people's app usage in a field-experiment, and focused on the mechanism in a lab-experiment. Short thread:

Check out our latest paper on experiences of absorption during a live (and livestreamed) classical concert! PDF: journals.sagepub.com/doi/pdf…

audience feels more absorbed during a live than livestreamed concert + embodied responses reflect absorption differently depending on social & musical features. New #musicscience published @Music_Science_J with Martin, Høffding, Nielsen

A bit more context on the new group (website follows soon): We will aim to understand how increased connectivity and online environments, specifically algorithmic curation and network structures, affect public discourse and political behaviour, as well as cultural evolution. 1/4

How effective can @one_sec_app be after one year of using it?
Our new publication at the @acm_chi conference on Hawaii shows:

(see diagrams)
It turns out to be a great companion to keep social media usage balanced long-term – not just as a quick digital detox fix.
I, myself, have been using one sec nonstop since I created it in 2020 and I couldn't live without it – and we see many happy users who are reporting the same.
I’m super thrilled to continue working on the app!
But not only that: we were also able to replicate our results from last year’s PNAS publication which showed a reduction of app usage by 57%.
@LukeHaliburton, Nađa, @albrechtschmidt, @GruningJ: Thanks a lot for the great collaboration 🥰🥰

Interested in meta-science? Come do a PhD with me and @maltoesermalte at @unibe in beautiful Switzerland. Open topic although we focus on error detection (see @error_reviews) and flexibility in measurement & methods. Email or DM either of us for details. Topic ideas welcome!
