Very excited to introduce InteroMap, a new bodily mapping tool designed to measure how we subjectively experience our bodily sensations, what we call interoceptive phenomenology πŸ§΅πŸ‘‡

New publication. Congrats to the whole team, and especially @paulbertin.bsky.social who led this effort. Thanks also to the editor (Nicolas Sommet) and reviewers, who desserve credit for improving our paper.

Instruction-based Replication Studies Raise Challenging Questions for Psychological Science A variety of psychological effects have been recently replicated in studies where participants merely received information describing experimental tasks, while participants experienced these tasks in ...

We discuss whether this Truth Beliefs Conditioning effect should be considered an experimental demand artifact, and whether it matters.

This research follows-up on a recent article that examined three outstanding questions raised by instruction-based procedures:

In this new research, we found that truth beliefs can be successfully conditioned:

Statements - true and false - are rated as more true after their pairing with positive than negative pictures.

This effect bridges research on evaluative conditioning and misinformation.

This overturns familiar assumptions of perceivers as β€œcognitive misers” and calls for rethinking how we conceptualize automatic evaluations.

Even with skin tone as a group marker and explicit instructions to form group-based impressions, people relied more on the actual characteristics of the individual they encountered.

In this research, we found that individuating information dominates social group information when forming impressions about members of newly learned social groups. This dominance was observed both on self-reports *and* more automatic measures *despite* conditions favoring group-level impressions.

I found the general discussion rather cautious, but this point might be further elaborated on. Another issue is that these manipulations are sometimes totally ineffective (Ps simply don't trust a hypothesis that runs against commonsense) but this does not seem to apply in this case 3/

As a result, demand effects may operate differently in these studies vs. in original procedures where the experimental hypothesis is not directly communicated. The same issue applies when probing demand effects based on instruction-based replication procedures 2/

If I may add a few thoughts, a major issue with this widespread approach to demand effects is that experimenters usually do not tell their Ps about their hypothesis. This communication creates unique demand characteristics that may consequentially depart from the original procedure 1/

The Great Implicit Bias Bamboozle Where were you when you first learned about implicit bias?

Major new paper by finds implicit measures like the IAT are no better than asking people directly about their biases. After decades of avoiding self-reports, turns out our sophisticated replacement tools work no better than what we abandoned. New post!

It is amazing that most organizations (businesses, media, NGOs, political parties) that worried about the threat of the far right for decades have spent no time or energy to thinking how to operate in a far right world. They just continue to do the same and are surprised by a different outcome.

Demand characteristics are a fundamental methodological concern in research with humans

Yet little is known about the magnitude and consistency of these effects

In a new paper, I, M. Wyatt, and @mcxfrank.bsky.social take stock of what we’ve learned via meta-analysis

After more than 7 years working on it, I’ve just submitted the manuscript for Discovering Statistics using R second edition. Tonnes more work on website/package and so on, but getting to this stage is monumental psychologically. It’s the book I feared I’d never finish.

Position of flask on magnetic stirrers can drastically affect reproducibility of experiments Comprehensive examination reveals improper siting of reaction vessels can affect catalyst formation, alter nanoparticle formation and change yields

New research shows that simply changing how a reaction vessel is positioned on a magnetic stirrer can significantly change a reaction's speed and product quality, influencing the reproducibility of results. #ChemSky #ScienceSky #EduSky
