Spock's Not One of Us! Exploring the In-Group Overexclusion Effect

by Mark Rubin in Mark Rubin's Social Psychology Research Blog

We all belong to many different social groups. Most of the time, it's fairly easy to work out who belongs to which group. But sometimes it's not that clear. In this post, I consider the mysterious effect that social psychologists have dubbed the in-group overexclusion effect.... Read more »

More bumetanide and autism discussion

by Paul Whiteley in Questioning Answers

For those with their ear to the autism research ground, the paper by Roman Tyzio and colleagues [1] must have sounded like a freight train coming given the volume of headlines that have been generated from this research (see here for example). Circling around the neurotransmitter, GABA (as in GABA dabba doo!), their findings based on two mouse models of autism, or rather autism and Fragile X syndrome - including the very interesting prenatal valproate (VPA) exposure model - suggested "hippo........

Depression: Ketamine Eyes Hath Seen The Glory?

by Neuroskeptic in Neuroskeptic_Discover

Ketamine: club drug, ‘horse-tranquillizer’, and… miracle antidepressant? I’ve blogged about the research behind the claim that ketamine has rapid-acting antidepressant effects several times. Since 2009, my view has been that it is impossible to tell whether ketamine has specific antidepressant properties, because ketamine has never been compared against an ‘active placebo‘ control. In trials, patients […]The post Depression: Ketamine Eyes Hath Seen The G........ Read more »

How being happy changes your personality

by Christian Jarrett in BPS Research Digest

Outgoing, conscientious, friendly people who are open to new experiences tend to be happier than those who are more shy, unadventurous, neurotic and unfriendly. It's easy to imagine why this might be so. Barely studied before now, however, is the possibility that being happy could also alter your future personality.Christopher Soto has conducted the first thorough study of this question. He analysed personality and well-being results for 16,367 Australians surveyed repeatedly between 2005 and 20........ Read more »

Retiring Procrustean Linguistics

by James Winters in A Replicated Typo 2.0

One example of where Procrustean Linguistics has seemingly led us astray is in the pervasive notion that ambiguity is dysfunctional for communication. Ambiguity exists at many layers of language. You have lexical ambiguity, syntactic ambiguity, scope ambiguity and many other types (see here). Broadly conceived, then, ambiguity corresponds to any state in which a linguistic code contains forms that are conventionally associated with more than one meaning (Hoefler, 2009). Why is ambiguity consider........ Read more »

Functional Networks in the Brain - Assessing the Difference between Dyslexics and Non-Impaired Readers

by John Wayland in Psych Radar

Dyslexia Action states that:Dyslexia is a specific learning difficulty that affects memory and processing speed which impacts on literacy development, mathematics, memory, organisation and sequencing skills to varying degrees. Dyslexia can occur at any level of intellectual development. It is neurological in origin and is seen to run in families. It affects up to 10% of the UK population at some level and can affect anyone of any age and background. Finn (2013) and her colleagues rece........ Read more »

How People Tawk Affects How Well You Listen

by Rebecca Schwarzlose in Garden of the Mind

People from different places speak differently – that we all know. Some dialects and accents are considered glamorous or authoritative, while others carry a definite social stigma. Speakers with a New York City dialect have even been known to enroll in speech therapy to lessen their ‘accent’ and avoid prejudice. Recent research indicates that they have good reason to be worried. It now appears that the prestige of people’s dialects can fundamentally affect how you process........ Read more »

A Dog Can’t Teach a Dog New Tricks (But It Can Teach a Wolf)

by Elizabeth Preston in Inkfish

In a dirt-floored room in Austria, a puppy sniffed and pawed at a wooden box with a treat inside. It circled the box over and over, unable to find a way in. Finally it sat at the feet of a nearby human and looked up at her appealingly, swishing its tail. The woman stared at […]The post A Dog Can’t Teach a Dog New Tricks (But It Can Teach a Wolf) appeared first on Inkfish.... Read more »

Anti-brain antibodies and behavioural profiles of autism

by Paul Whiteley in Questioning Answers

Anti-brain antibodies have been quite a recurrent theme in autism research circles over the past few years. I've covered research in this area a few times on this blog; primarily from the perspective of an intriguing bank of work looking at how the presence of circulating maternal auto-antibodies to foetal brain protein might heighten the risk of offspring autism (see here). If I also mention the words 'MAR autism' you can get a flavour as to how far this research has come, as well as the potent........ Read more »

Is Age-Related Mental Decline Not As Bad As We Think?

by Richard Landers in NeoAcademic

It’s well-supported in psychology that fluid intelligence (i.e. a person’s ability to solve unique, unfamiliar problems or remember large amounts of unfamiliar information, or otherwise flex their mental muscles) decreases with age.  There are several theories as to why – perhaps our brains become less efficient over time as our neurons age, or perhaps we […]Related articles from NeoAcademic:Can You Trust Self-Help Mental Health Information from the Internet?Inappropriat........

Autism and obstacles to medical diagnosis and treatment

by Paul Whiteley in Questioning Answers

The title of this post reflects the title of the paper by Marcia Datlow Smith and colleagues* which was given to me by Natasa (many thanks) a few days back. The paper is from 2012 so I don't think we can consider this a post about new research. Nevertheless the subject matter of the paper is potentially very important: "describing individuals with autism whose catastrophic illnesses were misdiagnosed due, at least partially, to their autism".@ WikipediaIt is indeed a pity that the Smith paper is........

Phenotypic plasticity, learning, and evolution

by Artem Kaznatcheev in Evolutionary Games Group

Learning and evolution are eerily similar, yet different. This tension fuels my interest in understanding how they interact. In the context of social learning, we can think of learning and evolution as different dynamics. For individual learning, however, it is harder to find a difference. On the one hand, this has led learning experts like […]... Read more »

Setting a Target Weight: An Arbitrary Exercise?

by Tetyana in Science of Eating Disorders

Achieving a healthy weight is a major goal of anorexia nervosa treatment. Indeed, a healthy weight is often seen as a prerequisite for psychological recovery. The fact that weight restoration is a crucial component of recovery is uncontroversial, the problem arises when it comes to determining what constitutes a healthy weight. How are ideal, optimal, or goal weights set? And who gets to decide?
Despite its recognized importance, there’s surprisingly little consensus on how target w........ Read more »

Just because you're tone deaf doesn't mean you aren't musical

by Christian Jarrett in BPS Research Digest

Psychologists estimate that around 4 per cent of the population have a specific impairment affecting their processing of pitch. Tone deafness, or "amusia" to use its technical name, runs in families and it often goes hand in hand with an inability to sing and to recognise and enjoy melodies. No wonder that people with amusia are usually thought of as not being musical.However, in a new paper Jessica Phillips-Silver and her colleagues argue that the musical deficits associated with amusia may hav........
