Why sadness lasts longer than other emotions

by BPS Research Digest in BPS Research Digest

Staying positive can feel like an uphill battle. No wonder: when Philippe Verduyn and Saskia Lavrijsen asked over 200 high-school students (average age 17) to reminisce about the duration of their recent emotional experiences, they found that sadness had an unfortunate habit of lingering, more so than any of the other 26 emotions studied, including joy, pride and relief.Indeed, the average duration of the episodes of sadness recalled by the students was 120 hours. At the other extreme, the most ........ Read more »

FC is a technique that has no validity

by Paul Whiteley in Questioning Answers

FC, by the way, refers to Facilitated Communication, a controversial technique which as the name suggests relies on a facilitator to support "the hand or arm of a communicatively impaired individual while using a keyboard or other devices with the aim of helping the individual to point and thereby to communicate." The quote for the title of this post comes from the paper by Ralf Schlosser and colleagues [1] who following systematic review, found "unequivocal evidence for facilitator co........ Read more »

Need to turn off the pain? Well now we can!

by Gabriel in Lunatic Laboratories

My sister suffers from chronic pain issues. I’ve written several posts about how her autoimmune disease is a special brand of pain that you will thankfully (almost certainly) never have to feel. While great strides have been made in pain management, there are still relatively few options that do not carry the risk of being extremely addictive. Well thankfully there is some new research and it offers hope, not just for my sister, but for the millions of people suffering from chronic pain that ........ Read more »

Synesthesia can be learned

by Janet Kwasniak in Neuro-patch

Synesthesia is a condition where one stimulus (like a letter) automatically is experienced with another attribute (like a colour) that is not actually present. About 4% of people have some form of this sensory mixing. It has been generally assumed that synesthesia is inherited because it runs in families. But it has been clear that […]... Read more »

Chikungunya Virus nsP2 and the ER stress response

by thelonevirologist in Virology Tidbits

Chikungunya virus (CHIKV) is the causative agent of an arthropod (mosquito) transmitted disease which is characterised by a high fever, rash, joint pain, and arthritis which was reported in 1952 in Tanzania but has spread since to Europe, Asia, Oceania and more recently to America, including the Caribbean and North America.
Here the inhibition of the ER stress response by the viral nsP2 protein is discussed in the context of viral infection. ... Read more »

Treatment Resistance in Eating Disorders

by William Yates, M.D. in Brain Posts

Clinicians treating patients with eating disorders find the challenge great with many treatment-resistant cases.To some extent, this is true of any clinical disorder. Outpatient treatment rolls and inpatient samples are over-represented by those failing to respond to initial interventions.A medical example is helpful here. Endocrinologists specializing in diabetes see more complicated cases where glucose control is difficult and diabetic complications are common.Diabetics with easy glucose contr........ Read more »

Illusion Makes People Speak with the Voice of Their Avatar

Think you’re in control of your own body? A simple virtual-reality session could not only make you feel like an avatar’s body is your own, but make you speak more like the digital character. First there was the rubber-hand illusion, a classic experiment that showed syncing up someone’s touch perceptions with what they see happening […]The post Illusion Makes People Speak with the Voice of Their Avatar appeared first on Inkfish....

Does Playtime for Cats Reduce Behaviour Problems?

by CAPB in Companion Animal Psychology Blog

Does few toys and no play equal issues with your cat?Photo: XSeon / ShutterstockA new survey of cat owners by Beth Strickler and Elizabeth Shull investigates how many toys the average cat has, how often their owner plays with them, and whether there is a link with behaviour problems. Since behaviour problems are a common reason for cats to be surrendered to shelters and so many cats are euthanized every year, it’s important to understand how meeting the behavioural needs of cats can lead to fe........

A Sex Researcher At A Furry Convention

 Patterns are soothing for left-brained folks like me, with the exception being those terrible patterned holiday sweaters that will come out of mothball-ridden closets soon (unsettling for everyone, really). Today’s images are from a paper describing a new micropatterning technique to look at plasma membrane proteins. The plasma membrane of a cell is riddled with many multi-protein complexes that facilitate communication and transport. These complexes provide a challenge to biologi........ Read more »

The gut microbiome in Down Syndrome

Why you're particularly likely to run your first marathon when your age ends in a "9"

by BPS Research Digest in BPS Research Digest

When we look at our lives, we tend to break them up into chapters, rather like the seasons of a TV box set. Potential dividers come in many forms, including the dawn of a new year, or the start of a new job. But if those events act as a marker between episodes, it is the decades of our lives that represent the more profound end of one series or season and the start of the next.According to the psychologists Adam Alter and Hal Hershfield, when we're on the cusp of one of these boundaries - in oth........

As A Bird - It's No Turkey

by Mark Lasbury in As Many Exceptions As Rules

The turkey is an amazing bird, beyond it’s taste on Thanksgiving. It has some really funky structures on its head, like the caruncles, wattle and snood, but research shows that they are important in mate selection. The question is why they have been retained even though they are artificially bred nowadays. Maybe they are for more than just mate selection. And yes....turkeys can fly.... Read more »

When Korea imposed a limit on working hours, did it make people happier?

by BPS Research Digest in BPS Research Digest

Across different professions, many people are familiar with the sense of having to deliver more with less, meaning clocking-off time falls later and later. One way to protect workers’ rights, and look after their wellbeing, is to introduce working hours restrictions. But a new paper by Korea University's Robert Rudolf investigates the impact of such a reform, and its conclusions are disappointing.Beginning its roll-out in 2004, the (South) Korean Five Day Working Reform was intended to manage ........
