Prenatal genetic testing and autism: a delicate subject

by Paul Whiteley in Questioning Answers

I realise that the paper by Lei-Shih Chen and colleagues [1] covers a most sensitive topic when it comes to the autism spectrum, exploring: "the attitudes toward PGT [prenatal genetic testing] and termination decisions of 42 parents of children with ASD [autism spectrum disorder]". Indeed, this is not the first time that this research group has looked at this area of autism research [2] and it seems like they will be talking about it further too (see here).I chose to discuss the most recent........

Is this the dark side of emotional intelligence? High EI linked with more delinquency among young women

by BPS Research Digest in BPS Research Digest

If, as research suggests, the psychological trait of sensation seeking is the catalyst for youthful delinquency, might high emotional intelligence (EI; having empathy for other people's emotions and good control over one's own) act as a calming restraint? That was the question Alison Bacon her colleagues posed in their study of 96 undergrads (average age 20; 48 women).Their "surprising and unprecedented" discovery was that for women, not only did high EI not moderate the link between sensation s........

The Attraction of Axons; the Moth or the Spider?

by Wadsworth in Wadsworth Guidance

An axon is attracted towards its target by guidance cues.  A moth flies towards the source of a pheromone.  A spider is sucked across the floor towards the nozzle of a vacuum cleaner.  Is the attraction of an axon towards its target more like the movement of the moth or the spider?credit: pmillera4External molecules direct the movement of the axon, the moth, and the spider.  In response to pheromone molecules a moth directs its movement toward the source of the pheromone.&nbs........

What do clinicians make of addiction recovery?

by DJMac in Recovery Review

Which teachers were the best when you were at school? Likely the ones who believed in you, connected with you, who had a vision for where you could go and who enthusiastically helped you get there. The same characteristics are likely to define the best clinicians too. In a study, published a few days ago, [...]

Yes folks... broccoli chemical impacts on autism presentation

by Paul Whiteley in Questioning Answers

Please do not adjust your set. Broccoli, or least a chemical found in broccoli called sulforaphane has, under placebo-controlled, double-blind experimental conditions, been reported to impact on the presentation of autism according to the paper by Kanwaljit Singh and colleagues [1] (open-access).Eat your greens @ Fir0002/FlagstaffotosI had to do a bit of a double-take myself when I first read about these results (see here).

Free Radicals and Wound Healing

by Gabriel in Lunatic Laboratories

Free radicals, said in the right crowd and you might hear someone scream for their life. Of course, to be perfectly transparent antioxidants have already shown to be bad in plenty of cases, so maybe it’s just bad PR. Still they were long assumed to be destructive to tissues and cells causing a host of age related problems with them. Well new research is showing that “free radicals” generated by the cell’s mitochondria—the energy producing “powerhouse” structures in the cell—are a........ Read more »

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

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.

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 »

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.
