Believing that the world is comprehensible, manageable, and meaningful (“sense of coherence”) predicts better health outcomes. But does a change in circumstance change one’s outlook? We found that for some women, pregnancy does. pubmed.ncbi.nlm.nih.gov/42250253/ #reprosky #🧠 #mhresearch #cogsci
Conceptual Graph showing a pregnancy as a possible change in set point for sense of coherence, which stabilizes in early adulthood. Graph showing first result of latent group modelling showing four sub groups identified - Low sense of coherence (21%), high (67%), rising (8%) and falling (3%)Hierarchical model showing factors that predict sense of coherence trajectory, results indicate that depression and a history of childhood trauma are the only significant predictors. Not age, parity, expectations about birth and postpartum, or social support postpartumGraph showing that depression is associated with low and rising trajectories and childhood trauma is associated with low and falling trajectories.

"If I think back 10, 20 years ago, [scientists] would never talk about funding. They're really just there to tell everyone about their work. Now, almost every single person comes in, brings up the issue of how bad the funding situation is. It is palpable." #science #auspol #WomeninSTEM

A woman's first pregnancy changes her brain, and new evidence from Straathof et al. shows that a second pregnancy does too, in distinct, but overlapping ways. What does this mean for cognition and the self? Jury is still out. @nav44s.bsky.social @sharnajamadar.bsky.social #neuroskyence #ReproSky

We have recently clarified our penalties for this. If a submission contains incontrovertible evidence that the authors did not check the results of LLM generation, this means we can't trust anything in the paper. 3/

The Australian clinical guidelines (among others) recommend the EPDS to screen for depression in pregnancy. Our validation study suggests only 1:2 women screening positive will have depression, and 1:5 screening negative are missed cases. tinyurl.com/epdsaus #ReproSky #mhresearch #PsychSciSky

Most postpartum women report experiencing cognitive failures. Our new study surprisingly finds evidence for NO cognitive differences between postpartum parents and non-parents, or mothers and fathers, and no effect of baby age up to two years. tinyurl.com/mtp2eb5s #ReproSky #PsychSciSky #CogSci

While that work focused on the potential impact of visceral signals on neural development & perceptual learning, our new paper considers how the top-down regulation of such signals across multiple scales may engender agentic control, selfhood, & neurobehavioural diversity

Our paper about the sense of self in first time pregnancy is out now in npj women's health! 🪞🤰 Check it out: rdcu.be/dHja6 #psysky #psychology #reprosky #🧠
Graphical abstract for the paper. The top panel shows findings that compared to never been pregnant peers, women pregnant for the first time show more body estrangement, more often feel out of control, more body visibility, greater attractiveness, femininity, pride, confidence and poorer learning. The bottom half of the figure depicts changes by trimester such that the first trimester is associated with a dip in sense of self, the second trimester shows consolidation so that the self is stronger in pregnant women than non pregnant peers and a relative return to baseline by the third trimester.

Pregnancy involves dramatic changes in the body and mind, but we know little about how the self changes, or the cognitive processes underlying this changing self. Check out my new preprint with @rebeccanineill.bsky.social and Sharna Jamadar where we aim to find out: osf.io/preprints/psya… A 🧵

Reflecting on a week of talks mixing my old and new areas of interest, starting the week with a talk about infant sleep by Doug Teti, the new science of consciousness by Anil Seth, and a series of great presentations on Women’s Health at the Richie Centre Colloquium. Bring on more exciting research!

Wednesday night, Prof Liad Mudrik expertly entwined philosophy and neuroscience for the first Leon Basser Lecture. Thanks to Monash M3CS and a bequest from the Basser family. Especially liked her intuitive argument against determinism as a problem for free will. My kind of evening! 🧠
Professor Liad Mudrik of Tel Aviv University stands next to a podium with a microphone delivering a lecture with a large projected slide that gives a roadmap for her talk. Slide text includes “1 The challenge - translating philosophical questions to testable predictions” and “2 what is consciousness - a definition of terms”
