I'm looking for EMA software that can do relative scheduling: participants report a time in their first daily questionnaire (e.g. "woke up at 7am"), then follow-ups trigger x hours after that reported time. I would greatly appreciate any recommendations!

It’s astonishing how many researchers seem to believe that a cluster analysis is such a sensible analysis that it needn’t even be justified through a coherent research question. Just cluster analysis go brrrrr

The framing around 'stricter age restrictions' feels disproportionate considering the magnitude of the effects.
I ran some rough calculations: Cohen's d ≈ 0.059 and 0.114 for the group comparisons on the cognitive composite measure.

In US adolescents, increasing social media use from ages 9–13 was associated with lower scores on measures of reading, memory, vocabulary, and composite cognition.

Everyone knows that temporal contiguity is important for associative learning. As the interval between a cue (e.g., a light) and an outcome (e.g., shock) gets longer, the conditioned response (e.g., freezing to the tone) is acquired less quickly.

😍 Our latest is out now in @commspsychol.nature.com. 🤩 We show with Bayesian modelling and experimental manipulation of uncertainty that developmental differences in social influence depend on differences in the internal uncertainty people have about their choice

Internal uncertainty impacts social information use in risky choice across adolescence - Communications Psychology
Adolescents’ choices are influenced by others. A social risky choice experiment and Bayesian modelling reveal that age differences in internal uncertainty, being unsure how to choose, relate to differences in susceptibility to social influence.

Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.
One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.
