Commentaries for Marcos Nadal's and my recent paper "Can arts-based interventions improve health? A conceptual and methodological critique" have begun to roll in. To keep track of them I am starting this thread.

TLDR: ABIs hold some promise but must be tested with the same rigor as other treatments.

Researchers harness brain activity to look at how we perceive faces from other racial groups differently Researchers at U of T Scarborough have used brain activity and AI to reveal why we have a tough time recognizing facial details of people from other races.

Excited to share my 1st Bluesky post: 2 studies reveal age biases in other-race face perception using GAN reconstruction and EEG. Congratulations to @moazshoura.bsky.social for this research - in collaboration with @dirkbwalther.bsky.social |

A Room with a View (of Art) Enhancing the built environment with visual art is a major program of the arts in healthcare movement. Does it work?

With the usual caveats of the need for more and better studies. Yet, the evidence does support the use of some kinds of art in clinical spaces. πŸ§ͺA Room with a View (of Art) | Psychology Today www.psychologytoday.com/us/blog/brai...

Target–distractor (T-D) Configurations and example search displays.  A Target–distractor configurations. The black cell indicates targets,  while the grey cells indicate the distractors in each condition. The areas in light grey indicate possible jitter zones for individual distractors. The exact position of the distractors can vary in different directions while maintaining the Euclidean distances from the target and configuration rule. B Example displays of search arrays. All three displays are the examples of target-present trials.

What features guide visual search for complex scenes? In her new APP paper, @songaeun.bsky.social uses scenes generated with a GAN to isolate features that guide search: layout, material properties, and lighting.

The Mirror Model of Art sees creativity and aesthetics as mirrors of one another.

The Mirror Model of Art sees creativity and aesthetics as mirrors of one another.

Creativity as aesthetics in reverse? How does the Mirror Model of Art hold up when seen through the lens of neuroscience? It doesn't.

How about omitting "connectivity"? Just call it "functional correlation." Much clearer description of the method without insinuating "connectivity," which can but doesn't have to be the source of the correlation of time courses of BOLD signals.
