Interleaving Study Is Not Interleaving Learning

by Joshua Fisher in Text Savvy

In the latest research, the authors found that a blocked schedule (presenting examples from one category at a time) outperformed an interleaved schedule (interspersing examples from all the categories) for category learning when the examples to be classified were more highly discriminable. This result was consistent across the two experiments in the study (p = 0.055 and p = 0.04). Importantly, however, although interleaving was a better strategy for learning categories of lower discriminability,........ Read more »

The Internet asks me about smelly things

by Rosin Cerate in Rosin Cerate

Whenever I'm working on a new post, I like to take a bit of time to check in on the stats for this blog. I'm particularly interested in what people are typing into their search engines to find their way here. For whatever reason, a post I wrote about what poisons smell like is very popular among users of the Internet. I'm taking this as a sign that people like to read about smells, so I thought I'd look into a couple of odour-related search queries via which people have found this blog.'type of ........

The New Norm When Missing SCAT3 Concussion Baseline Scores

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

A clinician needs to recognize that sex, competitive level, and attention deficit/hyperactivity disorder or learning disorder may influence SCAT3 scores. A medical professional could use normative conversion tables if they lack baseline scores and may not need to worry about practice effects with the SCAT3, except when retesting an athlete within 7 days....

Reconsidering the Autism-Spectrum Quotient (AQ) for autism screening?

by Paul Whiteley in Questioning Answers

A quote to begin: "The AQ's [Autism Spectrum Quotient] utility for screening referrals was limited in this sample. Recommendations supporting the AQ's role in the assessment of adult ASD [autism spectrum disorder], e.g. UK NICE guidelines, may need to be reconsidered."Taken from the paper published by Ashwood and colleagues [1], the findings from this team don't make for great reading if you happen to be a fan of the AQ as a potential screening instrument for adult autism. Indeed,........ Read more »

Specialized neurons in emotional memory play important role in fear

by Dr. Jekyll in Lunatic Laboratories

Fear memory encoding, the process responsible for persistent reactions to trauma-associated cues, is influenced by a sparse but potent population of inhibitory cells called parvalbumin-interneurons (PV-INs) in the amygdala, according to a new study.

Know your brain: Periaqueductal gray

by neurosci in Neuroscientifically Challenged

Where is the periaqueductal gray?















The periaqueductal gray, or PAG, is an area of gray matter found in the midbrain. The PAG surrounds the cerebral aqueduct (hence the name periaqueductal) and occupies a column of brainstem that stretches about 14 mm long. There are no obvious visible anatomical divisions within the PAG, but researchers have divided the PAG into four columns based on differences in connectivity and function: the dorsomedial, dorsolater........

Blogs, Papers, Plagiarism and Bitcoin

by Neuroskeptic in Neuroskeptic_Discover

Retraction Watch reports on a strange case of alleged plagiarism.

In February 2016, F1000Research published a paper called How blockchain-timestamped protocols could improve the trustworthiness of medical science. The authors, Greg Irving and John Holden, demonstrated the use of the bitcoin blockchain as a way of publicly verifying the existence of a certain document at a certain point in time. This approach, they say, could be used to make preregistered research protocols more secure. A prob... Read more »

Increased microbial translocation in ME/CFS

by Paul Whiteley in Questioning Answers

"The cause of ME/CFS [myalgic encephalomyelitis/chronic fatigue syndrome] is unknown, but gut dysbiosis could be contributing to some of the symptoms and their severity. Developing therapeutic interventions aimed at reducing local inflammation, restoring gastrointestinal tract immunity and integrity and modifying the intestinal microbiome may ameliorate ME/CFS symptoms in a number of affected patients."Those were the important conclusions reported by Ludovic Giloteaux and colleagues [1........

How to test for music skills

by Richard Kunert in Brain's Idea

In a new article I evaluate a recently developed test for music listening skills. To my great surprise the test behaves very well. This could open the path to better understand the psychology underlying music listening. Why am I surprised?

Does target shooting make teenagers aggressive?

by BPS Research Digest in BPS Research Digest

When the dust settles on the tragedy of the latest mass shooting, gun clubs usually see a spike in their memberships as people look to arm and defend themselves. At the same time, many others argue for greater gun controls, and from their perspective, recreational target shooting is very much part of the problem, not the answer.Anecdotally, this is borne out by the many killers who often turn out to have been target shooters. Indeed, in Germany after the teenage perpetrators of two spree atrocit........ Read more »

Are NETs involved in fighting Leptospira interrogans infections?

by Microbe Fan in Spirochetes Unwound

Neutrophils are the most abundant white blood cells in the bloodstream.  As the first immune cells to be recruited to infected tissues, they play a key role in the fighting microbial intruders.  It's long been known that they engulf microbes by phagocytosis, which results in the microbes being imprisoned within phagosomes inside the neutrophil.  Deadly proteases, antimicrobial proteins, and reactive oxygen species are released into the phagosome to kill the microbes.Another means ........

Weird stuff found in recreational drugs: Cocaine edition

This is the fifth and final post in a series on strange substances accidentally or intentionally added to street drugs. When you're done here, check out the posts on alcohol, meth, opioids, and pot/LSD.If a drug is being sold illegally, chances are its sellers have added crap to it in order to make more money. Cocaine is no exception to this deception. Substances added to nose candy because they resemble the drug but otherwise don't mimic or influence its effects include talc powder, flour, corn........
