calling all researchers who collect data from humans 🧠🧪 we are running a very brief survey (<1 min) about jsPsych, the software ecosystem for browser-based data collection. if you use jsPsych, or if you collect data with any other software, please fill it out at tinyurl.com/jspsych-census!
I am writing on behalf of the leadership of jsPsych, the software ecosystem for browser-based data collection used in experiments and surveys from many labs worldwide.

It has been difficult for us to figure out how widespread jsPsych usage is, because the software is freely available online and we do not collect any information about downloads, users, experiments posted online, etc. While the software has been cited in thousands of articles, jsPsych usage is likely more widespread than those citations imply, because not every project using jsPsych leads to a citation, and because there are also often substantial delays between actual jsPsych usage and a publication. As such, we are conducting a very brief census of jsPsych users.

If you collect data from humans using jsPsych or any other type of software, we would appreciate your filling out a very brief survey (<1 min) at tinyurl.com/jspsych-census. This will help us to understand how many people, labs, and institutions are current or former users of jsPsych, information that will help support the long-term sustainability of the jsPsych ecosystem.

We would also appreciate it if you could circulate this message to your lab, your department listserv, and your collaborators, to help ensure that it reaches as many members of the research community as possible. The survey is being distributed by Josh de Leeuw, Melissa Kline Struhl, and myself. Please contact me (sam@auckland.ac.nz) off-list if you have any questions about it.

Why are oxytocin study results so inconsistent? Methods get most of the blame, but the problem is also theoretical as existing accounts are too vague to falsify. In a new preprint, I formalise the Allostatic Theory of Oxytocin as a computational model osf.io/preprints/ps... 🧵
Oxytocin's effects on human behaviour are inconsistent across studies, persisting despite improvements in methodological rigour. Part of this problem is theoretical: existing verbal accounts do not specify predictions precisely enough to be falsified. Here I formalise the
Allostatic Theory of Oxytocin as a computational model, deriving eight testable propositions and evaluating each against simulation evidence. Three structural predictions that follow directly from the model's assumptions were confirmed. Of five genuinely discriminating tests, three were supported. The two unsupported propositions revealed boundary conditions the verbal theory could not identify. Formalisation underscored the importance of validating auxiliary assumptions
regarding optimal oxytocin dosing and the measurement of baseline endogenous oxytocin levels, without which tests of the theory cannot be conclusively interpreted. Altogether, this formalisation provides a more precise and falsifiable account of oxytocin's role in behaviour than
currently exists, and a template for incrementally refining verbal theories in psychology through formal specification.Figure 2. The allostatic theory of oxytocin as a directed graph. Each node is a variable in the equations, and each edge is a functional dependency. The graph complements the equations in Supplementary Text 1. Purple: oxytocin input Ω. Blue (solid border): the four oxytocin-dependent parameter functions specified by the verbal theory — sensing noise σ(Ω), learning rate α(Ω), prior weight w(Ω), and response gain γ(Ω). Blue (dashed border): the efferent coupling rate κ(Ω), a formalisation extension beyond the four verbal-theory components.
Grey: computation cascade operating each time step. Orange: environmental inputs — the predictive cue (pred. cue) feeds the observation, while the true current state drives passive body-state drift. Teal: body state y(t), driven by both passive drift toward s(t) (δ, oxytocin-independent) and efferent coupling toward x(t) (κ(Ω),
oxytocin-dependent). Red: output metrics: fitness f(t); allostatic load L(t); and efficiency E.

It’s great (derogatory) that you can work very hard to find out something incredibly important, and the main response you will get is a derisive “Gee, I’m shocked.” Somebody has to ACTUALLY DO THIS WORK! You can’t pursue justice by going “Your honor: I mean, duh.”
