Sleeping helps us to consolidate our procedural memories. This Canadian team managed to get people to go to sleep inside an fMRI scanner. They observed how the brain actually stores away memories.
This online paper also gives a great insight into the peer review process. If you scroll down, you can read the exchange between the editor of the journal and the author, which shows how peer review has improved the work prior to publication.
Network-wide reorganization of procedural memory during NREM sleep revealed by fMRI
Expert interrogators know that torture doesn’t work, but until now, no-one could prove it. Two psychologists at the University of Liverpool have conducted a detailed content analysis of 878 hours of taped interrogations, and have developed a training programme for interrogators called the Alycone Course. Using role-play to simulate difficult interviews, it is widely regarded as one the best interrogation training programmes ever.

In 1913, the early behaviourist John Watson wrote a piece which was to influence psychologists throughout the twentieth century.
“Psychology as the behaviorist views it is a purely objective experimental branch of natural science. Its theoretical goal is the prediction and control of behavior. Introspection forms no essential part of its methods, nor is the scientific value of its data dependent upon the readiness with which they lend themselves to interpretation in terms of consciousness. The behaviorist, in his efforts to get a unitary scheme of animal response, recognizes no dividing line between man and brute. The behavior of man, with all of its refinement and complexity, forms only a part of the behaviorist’s total scheme of investigation.”

This is a very readable account by someone with a brain tumour, about what it is like to be on the receiving end of various brain scanning techniques. Harry Stawson has a tumour in his right temporal lobe. He is left handed. The surgeons need to find out where the “eloquent” areas of his cortex – the parts responsible for language – reside in his slightly non-standard brain.
We tend to regard brain-scanning as a rather dry and academic topic, full of long biological words that are difficult to revise. This short article brings it down to earth in a very humane way.

New research has shown that reducing peoples’ noradrenaline levels boosts their metacognitive insight. Propranolol, a noradrenaline antagonist, increases peoples’ estimation of the accuracy of their decisions, without affecting the actual of accuracy of decision making.
There are potential applications in the treatment of OCD and schizophrenia.

The Rorschach test is often regarded as an example of the unscientific and subjective research methodology of the Psychodynamic school. In fact it was an early attempt at objectivity.
One research group gave the Rorschach test to Nazi prisoners in 1945, and rejected their own results because they couldn’t believe them. Those results are now being reappraised.

Lucid dreams are the experience of being conscious while dreaming. Most of us can only remember our dreams when we wake up. Many people achieve lucidity for a moment or two before waking up. But some people regularly have lucid dreams, in which the world around them seems tangible and real, and they are “awake”, and aware that they are dreaming.
Ursula Voss at the Goethe University Frankfurt has discovered a way to use electrical brain stimulation to induce lucid dreams. Kristoffer Appel at Osnasbrück University is now able to communicate with lucid dreamers inside their dreams. This might one day lead to new therapies for anxiety disorders.
One participant looked around his dream for something that might convey signals from outside. He was in a bus terminal, and spotted a ticket machine. Soon, it began to beep.
The article also contains instructions on how to achieve lucid dreams yourself.
