Two preconferences, one poster, one symposium, many events, and more reunions than I can count. #SPSP2025 is a wrap and I am so grateful for the reconnection. Until next year!

5) @psycheddiego.bsky.social extended interdependence research by surveying Mayangna participants to examine how shared fate impacts their cooperation. The more positive stake & shared fate in relationships, the more people tended to cooperate. #EPatSPSP2025 #SPSP2025

4) Ryan Dobson conducted a longitudinal progesterone study to re-examine the social support vigilance hypothesis. Between women fluctuations in P were predictive of vigilance but within woman fluctuations were not. #EPatSPSP2025 #SPSP2025

3) Sierra Peters tested competing predictions about sexual desire. Within subject fluctuations in desire for partners predicted greater desire for alternatives (& vice versa). Priming desire for alternatives increased desire for partners, but not vice versa. #EPatSPSP2025 #SPSP2025

2) Susan Chen examined how different life history correlates are related to youth gang involvement. Such an interesting study of an under-considered population! #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 23/02/2025

Last, some highlights from the #EPatSPSP2025 datablitzes: 1) A seriously cool talk by @wnmerrell.bsky.social about how we infer clustered (patchy) resource distribution based on an area’s hierarchicalness (& vice versa). Who knew lobstering could be so socially complex?! #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 23/02/2025

Yes. Women tend to infer gossipiness at higher rates than men, may have their information sharing perceived more as gossip, and may sometimes suffer likability penalities for gossiping. However, context matters. (3/3) @drmeltemyucel.bsky.social #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 23/02/2025

Gossip has many useful functions from info spreading to norm enforcement. Men & women tend to info share at similar rates. But are there gendered differences in what we perceive as gossip, & our social perceptions of gossipers? Does context matter? (2/3) @drmeltemyucel.bsky.social #EPatSPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 23/02/2025

Last but certainly not least in our fantastic invited lineup, @drmeltemyucel.bsky.social dazzled us with work on gendered perceptions of gossip. (1/3) #EPatSPSP2025 #SPSP2025

More formal modeling, in tandem with verbal theorizing, can increase the rigor and transparency of our science. @dconroybeam.bsky.social kindly offered some theory and reasoning templates to help us out! (5/5) #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

For example, we can more readily quantify jealousy in a given situation if we make some formal priors while setting up our theory (see example) (4/5) @dconroybeam.bsky.social #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

One solution? Express theories via formal mathmatical modeling. Formalizing specific predicted values allows us to more accurately compare, test, and update our assumptions than just making broad, directional verbal predictions (3/5) @dconroybeam.bsky.social #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

EPs tend to be good at generating verbal hypotheses. One problem with verbal theorizing though is that it’s like playing a game of telephone.. perception of hypothetical constructs varies across researchers & generates noise (2/5) #EPatSPSP2025 #SPSP2025 @dconroybeam.bsky.social

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

@dconroybeam.bsky.social gave all of us the talk we needed to hear about ways to improve our work through more formal theoretical modeling. Clear testable predictions are just as important to field replicability as good methods and analysis! (1/5) #EPatSPSP2025 #SPSP2025 #InDanWeTrust

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

Will is an archaeozoologist who uses a variety of field methods to tackle this Q. His work suggests horses were domesticated more recently than we once thought & the transition to using tamed horses spread rapidly across cultures. I can’t wait to read his book! (3/3) #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

Horses were one of our oldest preferred food sources, but they have since become central friends in many cultures and we build slightly murderous but beloved airport statues of them. How and when did this switch happen? (2/3) #SPSP2025 #EPatSPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

Will Taylor discussed how the emergence of our partnership with horses revolutionized human history (1/3) #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

Cost was the dominantly replicated factor across in person and hypothetical helping contexts, but other factors may still matter if measured differently. Thanks for the transparent assessment of the challenges with different social psych research methods @norabalboa.bsky.social! (3/3) #EPatSPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

@norabalboa.bsky.social conducted a field study that manipulated cost & reciprocation likelihood, then conducted a series of hypothetical scenario studies to examine whether field conditions could be replicated… (2/3) #EPatSPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 22/02/2025

I’m back at it today with more #EPatSPSP2025 recaps. @norabalboa.bsky.social gave a talk about the challenges of trying to overcome the hypothetical situation-real world behavior gap, in the context of prosocial behavior (1/3) #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 21/02/2025

@joshackman.bsky.social finished with a challenge to the field to do more interdisciplinary team science to further our knowledge in this area. Check out more of his lab’s work at their symposium today! (5/5)

Marjorie Prokosch @mlprokosch.bsky.social · 21/02/2025

@joshackman.bsky.social also covers how we deal with getting sick. A surprising (and scary) number of people conceal their illness, posing contagious risk. But people may do so because of pressure from conflicting goals. (4/5) #EPatSPSP2025 #SPSP2025

111

Marjorie Prokosch @mlprokosch.bsky.social · 21/02/2025

We believe we can use sight and sound to detect sickness cues, but are not as good at it as we think. We may be better at recognizing deviations from normal appearance / behavior better than sickness, per se (3/5) @joshackman.bsky.social #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 21/02/2025

Our psychology is attuned to detection and defense… except that pathogens are imperceptible so we are stuck relying on imperfect cues (2/5) @joshackerman.bsky.social #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 21/02/2025

Next up, @joshackman.bsky.social reminded us that disease remains a potent threat post-pandemic, and has been throughout human history - to the point that we’ve got psychological mechanisms dedicated to preventing and coping with it. (1/5) #EPatSPSP2025 #SPSP2025

Marjorie Prokosch @mlprokosch.bsky.social · 21/02/2025

@pdurkee.bsky.social finished with a case study of ways social emotions like anger and the adaptive problems they solve (e.g. being undervalued by others) can shape variation in personality constructs (the Big Few). (2/2) #EPatSPSP2025 #SPSP2025

020

Marjorie Prokosch @mlprokosch.bsky.social · 21/02/2025

First @pdurkee.bsky.social discussed the potential for adaptationist models to extend our knowledge of what shapes personality traits… (1/2) #EPatSPSP2025 #SPSP2025

@kristiansn89.bsky.social there’s no getting around it - both individual and larger systemic change are needed to effectively mitigate climate change. Taking either approach alone lowers feasibility, can delay action. Incorporating both can address shortfalls within each approach. #SP32024 #SPSP2024

Silly, but still a relevant example for a research methods class (tap to see full comic)..
