Will the UK's shrinking economy spoil Cameron's EU speech?

Any political high from Cameron's EU speech could be shortlived if figures released on Friday show that the UK economy shrunk in the final quarter of 2012.

In the absence of any unforseen hitches, David Cameron will finally deliver his long-delayed speech on Britain's relationship with the EU this week. It won't be today, the day of Barack Obama's second inauguration, or tomorrow, when thousands of French and German politicians and diplomats will gather in Berlin to celebrate the 50th anniversary of the signing of the Elysée Treaty (also known as the Treaty of Friendship) between the two countries, or at the end of the week, when Cameron travels to Davos for the 2013 World Economic Forum, leaving Wednesday as the most likely date for the address.

When Cameron gives his speech, promising that a Conservative government would seek to repatriate powers from Brussels before holding a referendum on the outcome (offering voters a choice between what Cameron calls a "new settlement" and withdrawal), he will hope, among other things, for a bounce in the polls. The last time that the Tories enjoyed a sustained lead over Labour was in December 2011 after Cameron's EU "veto". With reports of Conservative MPs reacquiring their taste for regicide, the PM is keen to show that there are things he can do to improve his party's dismal chances of victory at the next election.

But his speech risks being overshadowed by the other big event of the week: the release of the first estimate of UK quarter four GDP on Friday. After growth of 0.9 per cent in the third quarter, artifically inflated by the inclusion of the Olympic ticket sales and the bounce-back from the extra bank holiday in June, forecasters almost universally expect a negative figure. The government's own forecaster, the Office for Budget Responsibility, predicts that the economy shrunk by 0.1 per cent, while the National Institute of Economic and Social Research expects a contraction of 0.3 per cent.

A contraction in quarter four wouldn't represent an unprecedented "triple-dip recession" (that would require two successive quarters of negative growth), it would make it significantly harder for Cameron to claim that the economy is "healing" and embolden Labour to go on the attack. If the economy is shown to have shrunk in Q4, four of the last five quarters will have been negative.

We know from the pre-released extracts of Cameron's speech that the Prime Minister intends to bemoan the EU's "crisis of competitiveness". But if the UK economy, which has performed worse than almost any other in Europe, is shown to have shrunk again, his lecture could soon look ill-advised.

Tetris and sleep deprivation: how we can help emergency workers cope with trauma

First responders are at serious risk of developing PTSD during events like the Paris attacks. 

Some people seem able to deal with anything. They save a stranger from bleeding out in a bombed restaurant, protect passers-by from heavily armed gunmen, pull dead and dying people out of collapsed buildings, and they keep going because it is their job. These people are first responders.

When trauma goes on for days, as it has recently in Paris, however, the odds of them bouncing back from the violence, death and injury they are witnessing rapidly diminishes. They are at greater risk of developing a severe stress reaction known as post-traumatic stress disorder (PTSD). One study found that the worldwide rate of PTSD among first responders is 10 per cent, much higher than the 3.5 per cent rate among those not involved in rescue work.

Tetris to the rescue

So how best to address the problem? Research is in its infancy, but there are some promising studies. Emily Holmes’ group at the University of Cambridge has been looking at the benefits of playing Tetris, a video game, after a traumatic experience. The idea is that this could block the consolidation of traumatic memories so they don’t “flash back” later on.

For the study, her team first traumatised people by showing them distressing footage from public safety videos. The next day they invited them back into the lab to reactivate the memories with still images taken from the videos. One group then played Tetris for 12 minutes while the other sat quietly. Over the following week, the group who played Tetris had about 50 per cent fewer unwanted memories from the films compared to the group who didn’t.

The team concluded that playing Tetris helped individuals because it soaks up their visual processing capacity, making it harder for the brain to consolidate the visual parts of a traumatic memory.

Since it takes about six hours for the brain to cement a memory, the key is to play the game soon after trauma or within six hours of re-activating the traumatic memory. How long the helpful effects of playing Tetris will last and whether it will translate into helping people after real-life trauma is still unknown.

Talking it through

Other techniques, such as “updating”, taken from a highly-effective talking treatment for PTSD, may be more practical and easier to implement.

Like a detective, updating is a technique that focuses on finding new information and linking it to the case, the past memory. This is necessary because when the brain and body are in survival mode during trauma, the mind finds it difficult to encode all the relevant facts. Often key pieces of information that could make the memory less traumatic are lost. Updating links new information to someone’s memory of their trauma to make it less upsetting.

But can updating help to reduce unwanted memories after trauma?

We carried out a study, published in PLOS ONE, in which we traumatised people by showing them terrifying films of humans and animals in distress. We then divided our participants into three groups. One group watched the films again but were given new information about how long people suffered and whether or not they lived or died – essentially, they were updated. The second group watched the same films again but without the new information. And the third group watched films of humans and animals who were not in distress. The updated group had fewer traumatic memories and PTSD symptoms than the other two groups.

Updating is now being used by some UK emergency services. First responders will gather after critical incidents and update their memories of what happened before they go home.

Sleep deprivation

There are other techniques that may be helpful. One study found that depriving people of sleep may be useful in the aftermath of trauma.

But the same study found that a week after the trauma, people who had been deprived of sleep had the same number of unwanted memories as people who had slept well afterwards. Consequently, it remains unclear whether there would be any long-lasting benefits using this method. There are, however, certainly health risks linked to lack of sleep.

Still looking for a solution

To develop preventative interventions, we need to study newly-recruited emergency workers who haven’t yet suffered on-the-job trauma and follow them over time, spotting which “coping styles”, present before trauma, may predict their reactions afterwards.

For example, some people naturally react to stressful life events by dwelling on them, thinking about why they happened for hours on end. This strategy, called rumination, has been linked to PTSD in people who survived car crashes.

If rumination predicts PTSD in first responders, then preventative interventions could train people to spot when they are dwelling on an event and refocus their attention to the task at hand.

When we have identified which factors heighten emergency workers’ risk of developing PTSD, programmes can be developed to target those vulnerabilities. Only then can an intervention, directed at first responders most at risk of developing PTSD, properly protect them in their line of work.
