Emodiversity: A Mix of Emotions Is Healthiest?

by Neuroskeptic in Neuroskeptic_Discover

“Emodiversity” – a life containing a balance of different emotions – is good for you. So say psychologists Jordi Quoidbach and colleagues in a rather cool new paper (pdf). In two large surveys (with a total of over 37,000 responders), conducted in France and Belgium, Quoidbach et al. show that emodiversity is an independent predictor […]The post Emodiversity: A Mix of Emotions Is Healthiest? appeared first on Neuroskeptic....

The Psychology of Procrastination: How We Create Categories of the Future

by Jalees Rehman in The Next Regeneration

A fully rational approach to task completion would involve creating a priority list of tasks based on a composite score of task importance and the remaining time until the deadline. The most important task with the most proximate deadline would have to be tackled first, and the lowest priority task with the furthest deadline last. This sounds great in theory, but it is quite difficult to implement. A substantial amount of research has been conducted to understand how our moods, distractability a........ Read more »

Evolutionary psychologists expose the "shoddy" treatment of their discipline by textbooks

by BPS Research Digest in BPS Research Digest

The Gendered Society contained 12 errors about evolutionary psychology, morethan any other book in this evaluation. Evolutionary theory is universally accepted among the mainstream science community. And yet, when the evolutionary perspective is applied to human behaviour, the approach continues to meet with resistance, and in some cases outright disdain.A team led by Benjamin Winegard thinks part of the reason is because of the misrepresentation of evolutionary psychology in textbooks, esp........

Cognitive-Behavioural Therapy (CBT) for anxiety in autism

by Paul Whiteley in Questioning Answers

I'll readily admit that despite having a tinge of psychology running through my research career, I'm not overly enthused about the impact of the discipline on the autism spectrum down the years. I'm not necessarily just talking about the Freudian effect which set autism research back decades and shamefully added needless worry and stigma to those on the spectrum and their loved ones, but also the grand over-arching psychological theories which seemed, for example, to completely miss the 'heterog........

Fatigue Does Not Have A Leg To Stand On

by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field

Soccer players have impaired postural control after a fatigue-inducing task. The single-leg balance impairment was related to repeated sprint ability performance, which suggests that an athlete who was less fatigued by a sprinting task had less balance impairment.... Read more »

Language users or learners? Lexical evidence from spoken ELF

by Ray Carey in ELFA project

One of the key distinctions made in research on English as a lingua franca (ELF) is the difference between language users and learners. ELF data is typically approached from the viewpoint of second language use instead of second language acquisition. Rather than seeing non-native English speakers as perennially deficient pursuers of “native-like” proficiency, ELF researchers […]... Read more »

…but I thought a new knee would fix my pain!

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Working in an orthopaedic surgery department is quite enlightening. Along with discussions about ceramic vs metal implants and cartilage regeneration (I work with a team of researchers looking at how to create replacement cartilage), the topic of what counts as a surgical success in knee surgery also comes up from time to time. Knee joint replacement isn’t as successful as hip joint replacement for a number of reasons including the complex nature of the joint, the way the joint capsule is ........ Read more »

Nothing Sticks to a new Bioinspired coating for medical devices

by Gabriel in Lunatic Laboratories

Putting things in the body can be tricky, I mean we need things from joint replacements to cardiac implants and dialysis machines, these medical devices are needed to enhance or save lives on a daily basis. However, any device implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient the device is meant to help: blood clotting and bacterial infection. Problems that sound easier to fix than they actually are.... Read more »

What Really Drives Academic Citations?

by Neuroskeptic in Neuroskeptic_Discover

Citations are today the international currency of the scholarly economy. In theory, academic citations are the gold standard measure of the ‘impact‘ of a piece of work. If it gets other academics talking then it’s important. But why do individual academics cite particular articles?

Is EV-D68 causing mysterious polio-like symptoms in children?

by EE Giorgi in CHIMERAS

Bubble fun at the Santa Fe Renaissance Fair © EEG One of the twists in my latest book, Gene Cards, is an unknown pathogen threatening the fictional city of Liasis. I confess that when I came up with the idea I was a little nervous. My story is set in the future, and with all the state-of-the-art technology we already have, is it feasible to think that we will still deal with diseases without a known causative agent? The thing is, new viruses and new pathogens arise all the time. Take the f........ Read more »

Poop Pills, Yeah they are a Thing Now

When someone is lying it isn't too abnormal to hear someone say, "you're full of sh..." well you get the idea. Our poop defines us, the microbes that live in our digestive tract make it possible for us to digest food, absorb nutrients, and stay healthy. Heck they may even cause your cravings! Unfortunately sometimes --whether due to abuse of antibiotics or some medical condition like C. diff infection-- gut bacteria can work against us, leading to all sorts of problems. As of now, the only real........ Read more »

Efficacy of foetal stem cell transplantation in autism...

by Paul Whiteley in Questioning Answers

The recent news that researchers might be one step closer to 'curing' type 1 diabetes following the publication of the paper by Pagliuca and colleagues [1] brought back into focus how stem cell therapy might hold some promise for all manner of conditions. The idea that researchers could generate "hundreds of millions of glucose-responsive β cells from hPSC [human pluripotent stem cells] in vitro" still faces a few challenges, including overcoming the immune assault central to the autoimmun........

Saying NO to Our Food Craving Is Not as Simple as It Seems

by Wiley Asia Blog in Wiley Asia Blog - Life Sciences

Fitness junkies would not believe this, but our road to obesity could be greatly affected by the number and type of bacteria living within us. Researchers from UC San Francisco, Arizona State University and University of New Mexico suggest that a power struggle inside our gut happens daily. As it is a game of ‘survival-of-the-fittest’, our gut microbes would compete with each other over the availability of their preferred nutrient (e.g. sugar or fats). As a result, they influence our........ Read more »

Yet more air pollution and autism risk research

by Paul Whiteley in Questioning Answers

Air pollution and autism risk. It's a topic which has cropped up a few times on this blog (see here and see here and see here) with the majority of the research (but not all) suggesting that there may be something to see when it comes to such a correlation.Enter then the paper by Amy Kalkbrenner and colleagues [1] to proceedings, and their conclusion: "Our study adds to previous work in California showing a relation between traffic-related air pollution and autism, and adds similar findings in a........

Axon Guidance Meets Statistical Physics

by Wadsworth in Wadsworth Guidance

The proposition that the response of an axon to guidance cues is a random walk provides a different perspective of axon guidance.For the most part, Biologists like deterministic models, i.e. cause and effect.  From the deterministic point-of-view, axon guidance is caused when axon outgrowth activity occurs at the site where the neuron detects an external attractive guidance cue. But what if the direction of axon outgrowth activity were to rapidly fluctuates in different directions?  In this ........

How the Brain Heals After a Stroke

by Gabriel in Lunatic Laboratories

You have all the brain cells you'll ever have when you reach adulthood. That was the science lesson I was taught in high school from, maybe a misguided teacher, or maybe just misinformed, I do not know. That statement however is not true, we know that the brain is very plastic and ever changing. It's resilience still amazes us, even today with all that we know about it. Now a previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered, showing........ Read more »
