Our preprint has evolved! v2 of “Digital Behaviourism” is out now with a new title, new co-authors, and a deeper dive into the behavioural concepts that shape our online lives. It’s time to move beyond “screen time” and focus on function of online behaviours. osf.io/preprints/ps...

My favorite non-specification is when an abstract says the study (published in an international journal, of course) is based on a „national“ sample without naming the country.

Im my experience, if neither abstract nor title specify the population, it will be from the US in 99% of cases. I‘ve always wondered whether this was an established phenomenon 😄

📣New paper: Are Swiss adolescents' (gendered) self-perceptions towards ICT related to selection into VET occupations? 💡ICT interest ↔️ ICT-intensive careers 💡ICT self-concept ↔️ ICT-specialist occupations 💡Gender diff.s in ICT interest contribute to occupational segregation doi.org/10.1186/s404...

ICT interest and self-concept as determinants of Swiss adolescents’ vocational choices - Empirical Research in Vocational Education and Training
This study examines whether adolescents’ interest and self-concept regarding information and communication technologies (ICT) affect their subsequent career paths through the selection into different vocational education and training (VET) programs. Drawing on Eccles’ situated expectancy value theory and related theories, we argue that ICT interest and self-concept should influence adolescents’ vocational choices, possibly contributing to occupational gender segregation regarding ICT. Using longitudinal data from the TREE2 study (Transitions into Education and Employment) on 1,995 Swiss adolescents transitioning into firm-based VET, we find strongly gendered patterns. ICT interest predicts selection into occupations with greater intensity of basic and advanced ICT use, but this positive association is driven entirely by girls. In contrast, ICT self-concept significantly predicts ICT use intensity in future occupations only among boys. Selection into ICT specialist occupations is associated exclusively with adolescents’ ICT self-concept rather than their ICT interest, questioning whether girls’ lower average ICT interest represents a relevant barrier for entry into ICT specialist occupations in the context of VET. Our findings emphasize that ICT are an important content domain of adolescents’ vocational choices today and highlight how gendered interests and self-concepts towards ICT perpetuate occupational gender segregation.

Der Begriff Social Media ist hier m.E. schwierig - was fällt (nicht) darunter? YouTube? Twitch? WhatsApp? Das ist ein Grundproblem für die Regulierung und stellt auch die Aussagekraft dieser Statistik in Frage. bleibt die Zustimmung wirklich so hoch, wenn konkrete Dienste benannt werden?

I hate the argument that AI is being used in lots of jobs so students have to learn how to use it in school. AI is not that hard to use. Lots of jobs also use job-specific convoluted enterprise software and we don't teach them how to use those in school.

You may have heard of the back-door criterion and the front-door criterion for causal identification. Introducing: The door-in-the-face criterion (start with outrageous causal claim and hedge) and the foot-in-the-door criterion (start with trivial causal claim and escalate).

Not surprised by the results? Good for you! But the notion of harmful displacement is still alive and kicking, see e.g., a recent OECD report on children, screens and wellbeing. So far, we did not have a lot of robust evidence to show where adolescents take all the time to use their phones instead.

Great question! I tested this using a not-too-strict definition of little screen time (n gets too small otherwise) & found no displacement effects (neither screen nor other activities). Maybe cause these kids don't use the phone intensively either? Will consider this aspect for future revisions, thx
