The Psychology of Marriage: Choice or Arranged?

by Sam McNerney in Why We Reason

I love free samples. IKEA’s Swedish meatballs might be my favorite. They are delicious and put me in a furniture-buying mood. Sometimes, however, choosing between all those yummy samples is hard, and I’m not alone. In a study done several years ago researchers set up a jam tasting counter at a grocery store to see how [...]...

A bit of slug romance

by Africa Gomez in BugBlog

As their snail relatives, slugs are hermaphrodite, each individual producing eggs and sperm. Although some species regularly self-fertilise, in many others, individuals  - given the chance - will trade sperm with other individuals they encounter. I came across this pair of courting slugs under a fallen apple an evening last week. They are Deroceras panormitanum (thanks to Fauna, from WAB for the ID). At the right time of the year, and when meeting a potential partner, these slugs crawl........ Read more »

Patient Perceptions of Computed Tomographic Imaging and Their Understanding of Radiation Risk and Exposure – Part II

by Rogue Medic in Rogue Medic

When presented as 50 out of 121 who did not answer the question, it seems to be a large percentage, but it is only 50 out of about a thousand patients who did answer the question. Not a large percentage.

The authors included a footnote to the study that produced the numbers they are relying on, but they never specifically cite the X-rays per CT number from that study.... Read more »

How do extinction events kill so effectively?

“I am flying home from Europe in late August with nothing but a notebook and the 2011 Goldschmidt conference Geology giveaway issue to keep me occupied.

Slowing perception down

by Janet Kwasniak in Thoughts on thoughts

According to one way of understanding perception, it would not be surprising if perception was completed before conscious awareness could contain the percept. Why is it important to examine this? So that experiment methods of assessing conscious awareness are valid. Gregori-Grgic, Balderi and de’Sperati look at this question (see citation below) by slowing the processes [...]... Read more »

The Mysterious Mimbres

by teofilo in Gambler's House

Inspired by my recent visit to the Gila Cliff Dwellings, I’ve been reading about the Mimbres Mogollon culture of southwestern New Mexico.  As I noted earlier, the cliff dwellings themselves aren’t actually Mimbres, instead belonging to the Tularosa Mogollon culture more common to the north, and they postdate the “Classic” Mimbres period (ca. AD 1000 [...]... Read more »

Non-Aging Plant Gets Better Every Century

by Elizabeth Preston in Inkfish

Clinging to rock piles high in the Pyrenees, the plant Borderea pyrenaica has a modest lifestyle: It grows a new shoot every summer, flowers and fruits, then sheds its aboveground growth to survive the winter as a tuber. What's remarkable is how long this life lasts for. Individual plants have been known to live 300 years or more. Scientists headed up into the mountains to find out whether these plants, in all their years of living, ever actually get old.

"Senescence" is what we usual........ Read more »

The importance of sentimental landscapes

by Tim De Chant in Per Square Mile

When I was packing for the move from Chicago to Cambridge, I figured the transition would be easy for two reasons, both of which are related. First, the two cities share a temperate climate. I grew up in Wisconsin and love—absolutely love—the changing seasons. For example, I’m not merely unfazed by below zero weather, I [...]... Read more »

Ingroups, Identities, and In-Memoriams: Why We Must Remember Never To Forget

by Melanie T in PsySociety

It has been ten years since September 11th, 2001. When we remember the events of that day, we often tend to focus on how well we remember all of the seemingly-minor details (despite evidence that these memories may not be quite so accurate). What we were wearing. What we ate for breakfast. Where we were sitting while we watched the news coverage.

Our practically-obsessive focus on these memories actually indicates much more than we realize. Despite mankind’s ever-present focus on the wi........ Read more »

Things That Creep in the Night

by David Steen in Living Alongside Wildlife

I. inornatus

         Earlier this year, I found myself in a tropical downpour, surrounded by a Central American jungle, and with my nose running like a faucet.  I was afflicted with what my advisor had dubbed, “Black Elk Disease”, resulting in my words turning into grumbling sounds that seemed to emanate from the depths of my stomach. I tried to shake my grogginess off; I was supposed to head... Read more »

Friday Fun: Are you getting enough sleep?

by Psych Your Mind in Psych Your Mind

Do you feel like this guy?
Sleep is one of those basic needs we can't escape. But that doesn't mean we're planning our days to make sure we get our requisite hours of sleep each night. We live in a society where we're expected to burn the candle at both ends, and even our best attempts at sleeping well can fail with early morning meetings, last minute projects, late night social gatherings, children who need night time attention, sleep problems, a snoring roommate, or those tra........

3rd Roman Bioarchaeology Carnival

by Kristina Killgrove in Powered By Osteons

Between teaching, researching, and applying for jobs, I have not had as much time as I'd like to blog.  That partly explains the delay in this installment of the Roman bioarchaeology carnival, but the other reason for the delay is that, well, not much has happened in the past two weeks that I'd consider particularly Roman bioarchaeological.  I have, therefore, just a few offerings for this carnival...

Simple Jury Persuasion: Would “if it doesn’t fit, you must acquit” still work?

by Doug Keene in The Jury Room

Catchy slogans, phrases and themes have long been the hallmark of a persuasive courtroom presentation. But new research throws a question on whether they are as effective as we would like to think. Researchers compared the effect of both logos (brands) and slogans (phrases) on subjects. They discuss past research where showing the Apple logo resulted [...]

Sleep, Pain and Depression in Primary Care

by Kim Kristiansen in Picture of Pain

Close to half of all patients coming to primary care are experiencing sleep problems, but not necessarily presenting it. Increased experienced intensity of sleep problems are associated with significant increases of both average pain intensity and risk of Major Depressive Disorder. DoloTest provide an easy way to find and evaluate this coexistence. This is the conclusion of data I am presenting today at a poster.
