🚨 8 months after, this paper found its home at Science Advances. We came up with a generative brain network model based on game theory and found that the human brain is suboptimal both in terms of wiring cost and communication efficiency. Here's why: www.science.org/doi/10.1126/...

Are men and women becoming more alike? New research analyzing global survey data finds that differences in key economic preferences, such as trust and risk tolerance, are significantly smaller among younger generations than older ones.

New paper in PNAS! When the mind wanders, it often drifts to the body. We call this "body-wandering". These thoughts are often negative, but are associated with reduced ADHD & depression symptoms, driven by a distinct interoceptive-allostatic brain signature. pnas.org/doi/10.1073/pnas.2520822123
Graphical abstract showing four panels. Panel 1: a person in an MRI scanner with blue cognitive thought bubbles drifting from their head and pink body thought bubbles from their torso, with organs glowing inside. Panel 2: blue bubbles for cognitive items (Self, Words, Focus, Images, Future, Past) are larger than pink bubbles for body items (Breathing, Movement, Stomach, Heart, Skin, Bladder), with arrows showing body thoughts link to more negative and less positive emotion. Panel 3: physiological traces (EGG, ECG, respiratory) show higher arousal with body-wandering; a bar chart shows cognitive items (Past, Future, Repetitive, Vivid) correlate with more ADHD and depression symptoms while body items (Breath, Stomach, Skin, Heart) correlate with fewer.    
Panel 4: medial brain with thalamus, somatomotor cortex, and interoceptive regions highlighted, plus a chord diagram showing connectivity between these three regions.

Is there a single "interoceptive sense"? Our new study in @commspsychol.nature.com says: probably not. In 241 participants, cardiac and respiratory interoception were completely uncorrelated — only subjective confidence was shared across domains. www.nature.com/articles/s44... #psychscisky 🧪
  Graphical abstract showing three panels. Left panel, "Multiorgan Interoception Measures," depicts a translucent human body
   silhouette with anatomically rendered heart (red) and lungs (blue), accompanied by schematic icons for three
  psychophysical tasks: the Respiratory Resistance Sensitivity Task (RRST), Heart Rate Discrimination Task (HRDT), and an
  auditory control condition. N = 241 participants. Center panel, "Psychophysical Modelling and Individual Differences,"
  shows a fan of overlapping sigmoid psychometric curves in blue-to-red gradient representing individual variation in
  perceptual threshold (α) and precision (β), a hierarchical Bayesian model diagram, and icons for metacognitive bias and
  M-Ratio efficiency. Right panel, "Key Finding: No Cross-Modal Relationship," displays a scatterplot of cardiac versus
  respiratory sensitivity with a flat regression line (r ≈ 0, BF₀₁ > 6), a compact Bayes Factor heatmap with mostly blue
  null-supporting cells and one orange cell indicating that subjective confidence is shared across modalities (r = 0.51***).
   Takeaway: interoceptive ability is modality-specific.
