If you haven’t heard Paul Potts’ version of Nessun Dorma, you’re in luck!

For those who would like to compare Paul’s effort to some standard, I’ve included Pavarotti’s version here as well. This way, you can compare and contrast the two tenors. FYI - Paul Potts went on to win the competition, performing for the Queen of England.

The classic model of how brain cells communicate was put forth in 1943 by Warren McCulloch and Walter Pitts, at the time the first digital computers were being envisaged, and the McCulloch-Pitts model suggested that brain cells communicate in a binary fashion, represented by a “1” for firing and a “0” for not firing, much as a modern computer functions.

While it is common to say that a mammalian brain functions like a computer, this is a somewhat faulty idea, in part because the observation from the Traub lab suggests that gap junctions cause “short circuiting” as part of the brain’s normal functions. A real computer could not function if it short circuited. It is possible that these short circuits in the mammalian brain generally enhance brain function and adaptation to the environment, such as by permitting creative thinking, the combining of isolated facts into new ideas.

Researchers have found strong evidence for a novel type of communication between nerve cells in the brain. The findings may have relevance for the prevention and treatment of epilepsy, and possibly in the exploration of other aspects of brain functions, from creative thought processes to mental illnesses such as schizophrenia.

University of Portsmouth scientists have developed a powerful new tool that ‘freezes’ the memory of crime scenes in the minds of witnesses.

The tool - a self-administered interview applied by witnesses at crime scenes - combats natural memory decay by using the latest research in cognitive psychology techniques. It ‘freezes’ images and details of crime scenes and perpetrators in the minds of witnesses, particularly small and seemingly insignificant details that provide major leads for detectives that turn out to be crucial in solving cases.

Tests at simulated crimes scenes were remarkable with witnesses using the tool recalling forensically relevant information 42 percent more accurate than other witnesses who were simply asked to ‘report as much as you can remember’. The tests also revealed the witnesses using the self-administered interview (SAI) were 44 percent more correct with details about people - therefore, possible suspects - who had been involved in the event.

In another test there was a delay of seven days between witnessing the event and providing a full account. Half the participants completed self-administered interviews after witnessing the event while the other participants simply gave their name and contact details - as normally happens to a large number of witnesses at crime incidents. Scientists tested the group after seven days and found participants who had completed the SAI were still reporting almost 30 per cent more correct details than other witnesses.

The SAI protocol tool has been developed by Dr Lorraine Hope from the University of Portsmouth and collaborators Dr Fiona Gabbert (University of Abertay) and Professor Ronald Fisher (Florida International University) with funding from the British Academy. The scientists worked with police forces in England and Scotland to develop the witness ‘recall and report’ tool to record witness memory at the earliest possible opportunity - at the scene of the incident.

Dr Hope said the completeness and accuracy of eyewitness evidence decreases as the delay between witnessing an incident and recalling it increases. In other words, the longer the gap between witnessing the event and fully recalling what was seen under formal interview conditions, the less accurate and less complete a witness report is likely to be.

“Decades of research in cognitive psychology demonstrate that memory decay, or forgetting, occurs rapidly at first. In a witnessing situation, this ‘forgetting’ will occur naturally and within hours of the incident. As the delay between witnessing and formal interview increases to days, memory decay will level off. However, by that time, many useful and forensically relevant details or clues may be lost forever,” she said.

Dr Hope said the SAI tool could play a significant role for law enforcement as the benefits were obvious - witnesses have the opportunity to record their memories before any potentially crucial information is forgotten.

“The forensic implications of these findings for current police practice are considerable. At present witnesses are likely to engage in a very brief initial interview prior to giving a full statement at some later date. This very brief initial interview may actually have a detrimental effect on the ability of a witness to fully recall the incident at a later occasion. In other words, only the memory for the brief outline is strengthened - not the memory for the details, which can sometimes become harder to recall as a result,” Dr Hope said.

“Research has proven, for instance, that recalling an event before any substantial forgetting or memory loss has taken place means that the way the event is represented in memory is strengthened, making it easier to recall in future. In this way, an early recall attempt serves to protect or ‘freeze’ the memory against the course of natural forgetting. There is also some research to suggest that recalling only partial or brief outline information about an event or incident may in fact have a negative impact on ability to recall the incident more fully at a later stage.”

Dr Hope said using the techniques of the cognitive interview, and providing instructions to think carefully about the witnessing environment and report everything no matter how insignificant without resorting to guesswork, the SAI supports the witness in both the recall and reporting of as much information as possible before that information has been lost.

Autistic children are able to interpret the mental state of others by looking at their eyes, contrary to previous research, a new University of Nottingham study has found.

In findings that contradict previous studies, psychologists found that autistic children can ‘read’ a stranger’s mental state based on that person’s eyes. Autistic children have long been thought to be poor at interpreting people’s mental states based on facial expressions, especially expressions around the eyes.

Some researchers believe that this lack of ability could be central to the social problems experienced by autistic children and adults.

But the latest findings cast doubt on this hypothesis. A study at The University of Nottingham found that autistic children were able to interpret mental states when looking at animated facial expressions. The findings also suggest that the use of moving images, rather than conventional still pictures, gives a much more accurate measure of the abilities of autistic children.

Researchers hope that by increasing understanding of autism, their findings may ultimately help in the teaching and treatment of people with the condition.

Published in the latest issue of the journal Child Development, the study was led by Dr Elisa Back. Her co-researchers were Professor Peter Mitchell and Dr Danielle Ropar of the School of Psychology at The University of Nottingham.

Dr Back said: “Previous findings show that children and adolescents with autism may have difficulty reading mental states from facial expressions but our results suggest that this is not due to an inability to interpret information from the eyes.

“Surprisingly, autistic children seemed particularly reliant on the eyes and also the mouth when making mentalistic inferences.

“The conclusions of previous research are largely based on methods that present static photographs to participants. Our study indicates that a more accurate measure of the abilities of those with autism can be obtained through the use of sophisticated digital imaging techniques with animated facial expressions.”

The study compared two groups of autistic children, one group aged 10-14 and one aged 11-15, with two control groups of non-autistic children. They underwent a series of tests to see whether they could gauge the mental state of a stranger by looking at different parts of the face.

Researchers conducted two experiments in which the participants looked at a series of facial expressions on a laptop screen. In the facial images used, the eyes and mouth were either ‘freeze-framed’ in a neutral expression, or animated and expressive. By showing a sequence of different combinations, they were able to gauge which aspects of the face were used by the autistic children to ‘read’ someone’s mental state - and how successful they were.

In the second experiment, the 18 autistic children involved were as successful as non-autistic children in interpreting mental states, whether they saw the eyes in isolation or in the context of the whole face. This indicates that autistic children do, in fact, make use of information from the eyes - a finding that contradicts prior studies.

An estimated 588,000 people have autism in the UK, according to the National Autistic Society. A mental health survey by the Office for National Statistics found the prevalence of children and young people anywhere on the autistic spectrum is 0.9 per cent - almost one in every 100.
