Despite their genetic proximity, human and non-human primates differ in their capacity for beat induction, which is the ability to perceive a regular pulse in music or auditory stimuli and accordingly align motor skills by way of foot-tapping or dancing.... Read more »

I want to take you back to a post I published back in April 2012 (see here) on some very interesting work coming out of the Stanley Division of Developmental Neurovirology at Johns Hopkins by Dr Emily Severance.The Railway (Manet) @ Wikipedia It was concerned with the discovery that in cases of schizophrenia, measurement of anti-Saccharomyces cerevisiae antibodies (ASCA) revealed possible (probable?) signs of intestinal inflammation at greater levels than controls*.Alongside,........

Virginia Tech Carilion Research Institute scientists have demonstrated that ultrasound directed to a specific region of the brain can boost performance in sensory discrimination. Whales, bats, and even praying mantises use ultrasound as a sensory guidance system — and now a new study has found that ultrasound can modulate brain activity to heighten sensory perception … Read More →...

Conceptually, romantic and maternal love may be seen as very distinct, but it’s easy to see why humans have evolved these emotions: together, they lead to the production and safe-keeping of children – the foundation of species survival. It’s therefore not surprising that the biology of these two emotions involves similar areas of the brain, whilst also incorporating discrete areas that may account for the perceived difference between the two states. ...

"What does coffee smell like?" "What about lemon?" These questions are tricky for English speakers to answer because we tend to describe smells by referring to their typical source. So, an aroma that smells like coffee is described as, well, smelling like coffee. Ditto for lemon or cinnamon or rotten eggs.The fact is we don't have abstract words to describe the essence of these odorous experiences. This contrasts with our language for other sensory experiences such as colour. For example, the wo........ Read more »

This is the last post in my mini-series on the Mandometer® Treatment. (Links to earlier posts here: Part I, Part II, and Part III). In this post I’m going to continue examining Bergh et al.’s reasons for why eating disorders are not mental disorders (#6-10). In my last post I omitted something important: I didn’t define mental disorders, but to avoid repeating myself, please see my comment on the topic here.

Sometimes, your emotions rule your actions. It can be as simple as finding yourself unable to gracefully jump from a height, because your hindbrain will not listen to rational arguments about safety harnesses and belay lines, or as dramatic as blowing your top when you know you’re going to regret the scene later. It can also be very, very subtle – so subtle you may not even know it’s happening.... Read more »

What motivates someone to volunteer? This question lies at the heart of Jessica Rodell's dissertation research, now published in the Academy of Management Journal. Rodell looked at two differing perspectives on why we take on meaningful activities outside of a paying job. Are we after something we can't get from our nine to five? Or is it that the meaning we taste in our job makes us hungry - voracious, even - for more?Rodell's first study surveyed 208 people, three quarters of whom were women, ........ Read more »

It's been estimated that as much as 85% of funded research is never published. Sometimes it doesn't get done because gremlins get in the way, but often completed research is still not written up.

For psychologists, memory and learning are intimately intertwined. In fact, during the years of behaviorism in the early 20th century, the unobservable process of memory was completely replaced in the technical lexicon by learning (Miller, 2003).

A new paper brings worrying news for neuroscientists using fMRI to study memory: Across-subject reliabilities were only poor to fair… for novelty encoding paradigms, the interpretation of fMRI results on a single subject level is hampered by its low reliability.

Like Yahoo! did when they hired Marissa Mayer. At least one media outlet chose to illustrate their writeup of today’s study with Ms. Mayer.

Imagine your partner has just been arrested for drink driving. You're walking down the street not long after and suddenly you see a large poster of a brick wall. Is it a sign? A new study suggests your interpretation of that poster depends on the levels of inhibitory activity in a part of your brain. Marjaana Lindeman and her colleagues propose that it's human nature to read meaning into arbitrary symbols, but that sceptically minded people are able to ignore or suppress this instinct whereas su........
