🔊 dear BSKY people, I'm looking for a chatter, blabber, cocktail party background audio generator that has hopefully been used for research before. any tip or recommendation is appreciated. reposts are also appreciated as they may bring this post closer to someone that knows 🙌

Excited to share the first publication from my PhD project: how does low-dose LSD (10 and 20 µg) affect visual perception🧠 In 30 healthy volunteers (within-subject crossover) we assessed visual perception using visual contrast surround suppression (psychophysics), and subjectively (questionnaires).

Evidence for unconscious priming using a Bayesian single-subject approach
Abstract. Many studies have claimed the existence of unconscious priming, but a valid statistical procedure for substantiating such claims is often lacking

Have you used Bayes factor to test point-null hypotheses in Hierarchical models and wondered: 1. Bridge sampling (BS) or Savage-Dickey density ratio (SDDR)? 2. If SDDR, which density estimation method? 3. How many MCMC samples? 4. What's the cost-benefit trade-off? This may be of interest to you.

Very happy this is finally out 🎉. In this paper, we show that conf. reports are biased by a visual illusion, an asymmetrical base rate and a payoff scheme. Crucially, we show that only the visual illusion affects subj. experience, suggesting decision bias leaks onto confidence reports.
