Our new paper has just been accepted at AMPPS 😊

In psychology, we often bundle different things into composites (extraversion, depression, …). If the parts have different effects, the composite's effect is an ambiguous blend.

Above all, this is Lukas Junker's achievement.

in 2020 my lab quit Microsoft Word and began writing in R Markdown, an open-source document-publishing system that facilitates a clear, permanent link between statements in text (scientific prose) and the code producing analyses and visualizations supporting those statements (scientific analyses)

The long-term effects of parental singing remain unclear, however. In an offsetdesign exploratory 10-week randomized trial conducted in 2023 (N = 110 families of infants, Mage = 3.67 months, 53% female, 73% White), the study manipulated the frequency of infant-directed singing via a music enrichment intervention. Results, measured by smartphone-based ecological momentary assessment (EMA), show that infant-directed singing causes general post-intervention improvements to infant mood, but not to caregiver mood. The findings show the feasibility of longitudinal EMA (retention: 92%; EMA response rate: 74%) of infants and the potential of longer-term and higherintensity music enrichment interventions to improve health in infancy.

In response to our questions, an NSF spokesperson said that SBE has not been shut down. But with zero SBE-specific funding opportunities, no review panels, and dwindling numbers of staff, it's hard to see the directorate continuing for much longer.

The NSF-Social, Behavioral and Economics website no longer shows any of the programs that used to be there or the program officers. The only thing available is information on the National Center for Science and Engineering Statistics (NCSES). It is now only in name at NSF www.nsf.gov/sbe

And for those interested, here is the absolute error and bias ("signed error") in presidential election polls going back to 1940. (pp. 18-19 of the report.) As you can see, overall accuracy hasn't changed much since the mid-1980s. Notable years of Republican bias were 1984, 2000, and 2012.
