Stapel – the final report
It’s nearly 18 months since the social psychologist Diederik Stapel was sacked for research fraud and yet still the fall-out continues. Understandable perhaps when you consider the mind-boggling scale of his misdeeds – 55 journal papers published over 15 years are now known to be tainted, together with numerous book and dissertation chapters.

The gory details emerge in the final, exhaustive joint report of the three investigative committees that were established at each university where Stapel worked (tinyurl.com/c9ugz7y). They are the Levelt Coordinating Committee (at Tilburg University where Stapel last worked), chaired by Professor of Psycholinguistics Pim Levelt; the Noort Committee (at the University of Groningen); and the Drenth Committee (at the University of Amsterdam). Their final ‘Levelt report’ is based on an exhaustive analysis of Stapel’s entire research output, together with interviews with Stapel, his co-authors and students.

Consistent with an earlier interim report (see News, December 2011), the final report concludes that Stapel’s co-authors and students were not complicit in his fraud. In fact, it is thanks to three brave whistle-blowing students that his crimes were finally uncovered. However, the report raises an eyebrow at the failure of so many co-authors to spot the fact that Stapel was engaging in extensive fraud.

Part of the explanation for how Stapel was able to prosecute his fraud for so long is related to his status at his various research institutions. The report describes how at Tilburg he was considered a star and seen by his colleagues and students as charismatic, friendly and incredibly talented. He was afforded special financial privileges by the university in keeping with his prestige. He even taught his department’s scientific ethics course. Many students became personal friends. Stapel used his power to stamp out quickly any signs of doubt or dissent. The contact point for concerned students at Tilburg – the university’s Rector – may have seemed too lofty and distant, the report says, thus deterring many potential whistle-blowers.

It is in its consideration of the wider contributing cultural factors that the final Levelt report is proving controversial. While acknowledging that it cannot comment on the status of social psychology as a whole (based only on an analysis of Stapel’s research), the report nonetheless goes on to conclude that there was ‘a more general failure of scientific criticism in the peer community and a research culture that was excessively oriented to uncritical confirmation of one’s own ideas and to finding appealing but theoretically superficial ad hoc results’.

The report is particularly concerned with the prevalence of ‘sloppy science’ practices, including selective reporting and data polishing, which, based on interviews with co-authors, they suggest is endemic in the field of social psychology. This is based in part on interviewee testimony stating that journal reviewers are often the ones to encourage questionable practices, such as dropping experiments with negative results and inserting pilot studies retrospectively. ‘Not infrequently reviews [of social psychology journal articles] were strongly in favour of telling an interesting, elegant, concise and compelling story, possibly at the expense of the necessary scientific diligence,’ the report says.

The British Psychological Society’s own Social Psychology Section has criticised this aspect of the report. Writing to the Times Higher Education Supplement on behalf of the Section (see 'Letters', this issue, for a fuller version of the letter), Stephen Gibson at York St John University, points out ‘… there are no grounds for concluding either that research fraud is any more common in social psychology than other disciplines or that its editorial processes are particularly poor at detecting it’, adding that: ‘Our subdiscipline does not deserve the harm to its reputation that may be provoked by the careless implication of “unique” deficiencies.’

The final Levelt report was also criticised by the European Association of Social Psychology in an open letter to its members in which it denounces ‘attacks against social psychology as unwarranted and unscientific’. Citing research showing that social psychology has in fact suffered fewer frauds than other disciplines and that it is unusual for peer review to detect fraud in any field of science, the Association’s Executive Board suggest that the report ‘itself seems to be an unfortunate example of the verification bias that it seeks to criticize’.

Following an approach from us, Willem Levelt and the chairs of the other investigating committees have jointly published a sole and final rejoinder to these and other criticisms in this issue of The Psychologist (see 'Letters'). Levelt et al. acknowledge that they did not compare the situation in social psychology with other disciplines. ‘However,’ they note, ‘such a comparative investigation was not part of the Committees’ commission. The terms of reference, specified in the opening section of the report, limit the investigation to determining which publications (co-)authored by Mr Stapel are fraudulent and to offering a view on the methods and the research culture that may have facilitated this misdemeanor.’

Meanwhile, Stapel has given his side of events in a 315-page autobiography entitled Ontsporing (Derailed), described by the Dutch psychologists Denny Borsboom and Eric-Jan Wagenmakers
as ‘priceless and revealing’ in a review for the Association for Psychological Science.

Stapel says the rot began when he was sitting alone in his office in Groningen and he changed ‘an unexpected 2 into a 4’. The story that follows, Borsboom and Wagenmakers say, reveals that Stapel’s trickery was ‘remarkably unsophisticated, even clumsy.’ There are also further signs of an individual who struggles to accept responsibility – ‘Nobody ever checked my work,’ Stapel complains – and of a man who remains untrustworthy. According to the reviewers, the final, ‘unexpectedly beautiful’ chapter is full of lines taken from the writers Raymond Carver and James Joyce, entirely unattributed but for a listing buried in the appendices. ‘The reader cannot help but wonder whether there may be yet another literary layer of deceit under the apparently candid book,’ write Borsboom and Wagenmakers.

DSM-5 approval and disapproval

It’s been a tortuous, torrid process, but the American Psychiatric Association (APA) has finally approved the next edition of its Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which is due for publication in the spring. APA President Dilip Jeste said: ‘We have produced a manual that best represents the current science and will be useful to clinicians and the patients they serve.’

Some of the headline changes include: merging Asperger’s Disorder into a single Autism Spectrum Disorder diagnosis; the creation of a new Hoarding Disorder diagnosis; a new Disruptive Mood Dysregulation Disorder to diagnose children ‘who exhibit persistent irritability and frequent episodes of behaviour outbursts three or more times a week for more than a year’, and removal of the bereavement exclusion from the diagnosis of depression (previously, the DSM advised against diagnosing major depression less than two months after a bereavement, unless the symptoms were very severe).

Unlike previous revisions, the new code has not experienced a massive increase in the number of diagnostic categories. ‘We have sought to be conservative in our approach to revising DSM-5. Our work has been aimed at more accurately defining mental disorders that have a real impact on people’s lives, not expanding the scope of psychiatry,’ said David J. Kupfer, chair of the DSM-5 Task Force.

The decade-long effort to revise US psychiatry’s diagnostic code has never been far from controversy. The British Psychological Society published its own reservations last year, stating it was ‘concerned that clients and the general public are negatively affected by the continued and continuous medicalisation of their natural and normal responses to their experiences.’ Along the way, there were also high-level resignations from the DSM-5 Task Force, as well as repeated accusations of vested interest.

The acrimony has continued since news of the DSM-5 approval was announced in December. Most notably, the Washington Post accused many of the DSM experts (especially those who recommended the removal of the bereavement exclusion from the depression diagnosis) of having links to pharmaceutical companies – companies that the Post implied will benefit from the change, as bereaved patients become eligible for antidepressant prescriptions. Based on financial disclosures, the Post claimed that ‘Eight of 11 members of the APA committee that spearheaded the [bereavement exclusion] change reported financial connections to pharmaceutical companies.’

The APA has answered these charges. Kupfer issued a statement reiterating the extensive measures taken by the DSM-5 Task Force to avoid bias, including the creation of a five-member expert group with no industry ties who approved all guidelines before they were published. ‘Removing the bereavement exclusion helps prevent major depression from being overlooked and facilitates the possibility of appropriate treatment including therapy or other interventions,’ Kupfer said. - CJ

Towards better communication

The Department of Education have published results from the Better Communication Research Programme (BCRP), the largest-ever UK study of speech, language and communication needs (SLCN). The programme was led  by educational psychologist Professor Geoff Lindsay (CEDAR, University of Warwick), a Fellow and Honorary Life Member of the British Psychological Society. Lindsay was supported by fellow psychologist Professor Julie Dockrell (Institute of Education, University of London), and speech and language therapists Professor James Law (Newcastle University) and Professor Sue Roulstone (University of West of England, Bristol).

Professor Lindsay told The Psychologist that the BCRP comprised 10 research studies including a prospective study of children with language impairment or ASD; a review of the efficacy of interventions; and the development of a Communication Supporting Classrooms Observation Tool. The research included studies of practice of speech and language therapists and educational psychologists as well as teachers, and the perspectives of children with SLCN and their parents. Other psychologists leading projects include Professors Maggie Snowling and Charles Hulme.

‘Devised as a practice- and policy-related research programme, the aim throughout was to use rigorous quantitative and qualitative research to address practice and policy issues,’ Professor Lindsay said. ‘We’re now working with the Communication Trust to disseminate the findings of the BCRP and to develop practical resources.’

The research was welcomed by the Children and Schools Minister Edward Timpson, who said: ‘The Better Communication Research Programme provides a rich and extensive source of evidence on what works in identifying the needs of children and young people with speech, language and communication needs. It will help all those commissioning and providing services, across education and health, to improve their planning. It will also improve the effectiveness of the support provided, and help in developing a welcoming classroom that supports communication.’ - Jon Sutton

Public perceptions of psychology

Eighteen months ago, the clinical psychologist Scott Lilienfeld published a clarion call in the American Psychologist about scepticism towards psychology(see News, August 2011; tinyurl.com/
news0812
). He reminded us of data showing the widespread public belief that psychology is not a proper science. He also diagnosed the causes, including people’s overconfidence in their understanding of psychological concepts, and the high media profile of pseudoscientific quacks. Now the issue has been revisited with publication of three commentaries on Lilienfeld’s article (tinyurl.com/byfpz58).
Leonard Newman and colleagues at Syracuse University felt Lilienfeld had missed a key observation – the fact that the public have an inclination to prefer some explanations over others. For instance, people often favour dispositional explanations for bad behaviour. And when psychologists propose social explanations, the public interpret this as a sign that the psychologists are attempting to exonerate the offenders. People are more likely to accept psychological explanations when these build on their intuitions, Newman et al. proposed, for example through interactionist models. ‘Such an approach will more generally be the most effective way to defuse reflexive scepticism,’ they said.

Warren Tryon at Fordham University felt Lilienfeld had been too generous towards the achievements of psychology. To Tryon, many psychological models – such as the biopsychosocial model – provide mere lists of ‘ingredients’, without any explanatory mechanism. He also criticised psychology for alluding to non-existent psychological substrates for its models, out of fear of biological reductionism. Tyron believes that psychology can be more persuasively integrated with biological accounts through connectionist models, facilitating ‘the public perception of psychology as a serious science’.

Most critical of Lilienfeld’s article was the historian Thomas Teo at York University, Toronto. Teo argued that psychology would gain more credibility by being more open about its limits, the inevitably biased personal and political positions of psychologists, and the way that psychological interpretations are affected by history and culture. ‘Instead of a celebratory selling of goods to the public, I recommend knowledge about the limitations of psychological methods, modesty when making generalisations, and, most of all, honesty about the contingencies of knowledge produced in psychological research,’ Teo wrote.

Lilienfeld welcomed the responses and concluded with his own timely message. ‘Ultimately, our field will earn credibility in the eyes of the public not by instilling false hopes but by striving for intellectual honesty, he said. ‘This honesty, in turn, impels us to be circumspect when telling the public what we know – and to openly acknowledge what we do not know.’ - CJ


National honours in psychology

We’re delighted to report that two psychologists were recognised in the New Year’s Honours List. Professor David Clark, an Honorary Fellow of the BPS, is appointed CBE for services to mental health. Clark, a clinical psychologist, established the Oxford Centre for Anxiety Disorders and Trauma at Oxford University in 2012, where he’s currently based. He continues to conduct ground-breaking research on cognitive approaches to anxiety and is currently acting as National Clinical Advisor to the Improving Access to Psychological Therapies programme in England. ‘I am honoured and delighted to receive this award which provides important recognition in the UK of the value of scientific research on psychological therapies and their dissemination,’ Clark told us, ‘as well as the need for public transparency in reporting the outcomes of our mental health services.’

Chartered Psychologist Professor Michael Brookes, an Associate Fellow of the BPS and director of therapeutic communities at HMP Grendon, is appointed OBE for services to HM Prison Service and the care of prisoners. HMP Grendon in Buckinghamshire houses prisoners diagnosed with antisocial personality disorders, with each wing operating as an autonomous therapeutic community. Brookes, a forensic psychologist and also visiting professor at Birmingham City University, said: ‘I am very encouraged that the therapeutic work undertaken at Grendon Prison has again been nationally recognised. Grendon is a unique penal establishment with a regime focused on addressing residents’ offending behaviour and psychological disorders.’ Brookes is currently focused on ‘continuing to ensure the safe and effective delivery of therapy in a world of diminishing resources and, with the opportunity afforded by my visiting professorship at BCU, publishing articles on Grendon’s work.’

Other honours of relevance to psychology went to the psychiatrists Janet Treasure and Simon Wessely. Professor Treasure, based at the Eating Disorder Unit, South London Maudsley Hospital NHS Foundation Trust, is appointed OBE for services to people with eating disorders. Wessely, Professor of Psychological Medicine at the Institute of Psychiatry, is knighted for services to military healthcare and psychological medicine. cj


IQ ‘myths’ debunked?

Psychologists in Canada have rekindled a century-long debate about whether intelligence is a unitary construct. Adam Hampshire, Adrian Owen and Beth Parkin at the University of Western Ontario, together with former New Scientist editor Roger Highfield, claim in their Neuron paper that intelligence is made up of three components – memory, logic and verbal – each reflected in the functioning of a discrete brain network (tinyurl.com/a6w48ym).

The researchers arrived at their conclusion based on the results of a 30-minute online cognitive test completed by over 100,000 participants, combined with the results of an imaging study, in which 16 people had their brains scanned while they performed the same half-hour cognitive challenge.

The test contained 12 types of task, including spatial, verbal and memory batteries. The different types of task led to different amounts of activity in the three brain networks. Tasks drawing more on memory were associated with greater activity in a network located towards the front of the brain; tasks tapping logic were associated with greater activity in a network spanning frontal and more posterior regions; verbal tasks were associated with more activity in fronto-temporal network.

Hampshire and his colleagues said this tripartite view was supported by demographic data collected as part of the online testing. For instance, based on an analysis of a subset of 44,600 participants (omitting incomplete tests; the very young and old), memory and logic performance declined with age, but verbal performance did not. Excessive smoking adversely impacted on memory and verbal performance, but not logic. ‘Human intelligence is most parsimoniously conceived of as an emergent property of multiple specialised brain systems,’ the researchers concluded, ‘each of which has its own capacity.’

Presenting their findings to the media, Hampshire and his team were less restrained. ‘The world’s biggest study of its kind has put paid to the simplistic idea that we can use an IQ figure to describe the astonishing abilities of the human brain,’ wrote Highfield in a piece for the Daily Telegraph. In an article for the Discovery Channel titled ‘The myth of IQ’, Owen wrote that ‘what we often call intelligence… is too complex to boil down to a single factor or “IQ”.’ A university press release boasted that the IQ myth had been ‘debunked’.

In the parlance of intelligence research, it seems the researchers are attempting to dismiss the idea of ‘g’ or ‘general intelligence’ – the fact that people’s performance on one type of intelligence task tends to correlate with their performance on other types of test – first noted by the British psychologist Charles Spearman at the beginning of the 20th century.

It takes more than a single paper to turn over such an established concept. Many psychologists and commentators have taken to social media outlets to air their criticisms of the new paper and the researchers’ public pronouncements, pointing out, for example, that there is evidence of g in the new data and that previous intelligence studies have featured over a million participants.

We asked Professor Richard Haier at University of California, Irvine, an expert on the neural correlates of intelligence, what he thought. He didn’t hold back. ‘The University of Western Ontario should be ashamed for hyping conclusions and quotes from the authors that actually are not supported by the paper,’ he said. ‘If the researchers approved the University press release, they need to explain why they think IQ is “debunked” when their own data show a general factor (g) and why they assert that the claim that a single number like an IQ score captures the complexities of human intelligence is a myth when,
in fact, no one has ever made this claim. No one. They “debunked” a viewpoint that doesn’t exist.’

What about the merits of the study methodology? Haier was critical here too. ‘[It] uses a type of factor analysis that is designed to create independent factors whether they exist in nature or not. This essentially negates their conclusions and does not advance the field at all,’ he explained. ‘There are many brain imaging studies that already show different networks related to intelligence scores so I don’t see any news here, especially since they studied only 16 people. There are many mysteries about intelligence and the general factor. Now there is a new one – how did this paper get published?’ - CJ

NHS developments
The Coalition Government has announced that mental health patients in England are to be given more choice about where and how their condition is treated on the NHS, bringing their treatment more in line with the situation for physical conditions. The promise was made in the government’s response to its consultation ‘Liberating the NHS: No Decision About Me, Without Me’. The government also published details in December of the six sites piloting the extension of the Improving Access to Psychological Therapies programme to people with severe mental illness, including psychosis and bipolar disorder (tinyurl.com/bmh8k5g).

Global young academician
Chartered Psychologist Rob Jenkins (University of Glasgow) has been selected for membership in the Global Young Academy (GYA) – the voice of young scientists around the world. The 172 current members include leading young scientists from 54 countries and all continents. Four of the current members are based in the UK. Rob is the first UK psychologist to be selected for the GYA.


MEDIA AWARDS
The writer and radio presenter Claudia Hammond received the British Neuroscience Association’s Public Understanding of Neuroscience Award in December, at the organisation’s Christmas Symposium. A psychology lecturer and BPS member, Hammond was awarded our own 2012 Public Engagement and Media Award, as well as the Society for Personality and Social Psychology’s 2012 Media Achievement Award. Ms Hammond is currently presenting BBC Radio 4’s Health Check series (see also January’s Reviews section).

Sentencing Policy
The Sentencing Council for England and Wales, which sets guidelines for the courts to follow, has proposed updating the sentencing policy for sex offences, to take into account the effects of psychological harm. This includes issuing more serious charges when violence is threatened, because ‘fear of escalation of an attack is likely to increase the psychological harm on a victim’.

The Council is seeking feedback on its proposals until mid-March – see www.sentencingcouncil.org.uk.

No gas, no research
A lack of helium has forced the Oxford Centre for Human Brain Activity to suspend its research using the brain-imaging technique of magnetoencephalography. Mark Stokes,  a senior research fellow in the University’s Department of Experimental Psychology, explained in an article for The Independent how helium is required to obtain temperatures close to absolute zero. ‘This is not the first time we have had to halt operations over the past 12 months, and we fear more difficulties over the coming year,’ he said, blaming privatisation for the turmoil in global supplies. 

top blog
The Guardian Teacher Network chose a blog post by the Chartered Psychologist and psychology teacher Marc Smith (tinyurl.com/bzql3gk) as one of its top ten posts of 2012. In his ‘fascinating’ piece ‘Are iPods and Xbox games the right reward for good classroom behaviour’, the editors said Smith ‘explains and explores the thinking around costly incentive schemes and profiles some key studies and theories around rewarding behaviour.’ 

 

A richer understanding
Catherine Loveday (University of Westminster) reports from the Society’s student-focused London Lectures

This year’s London Lectures opened with Professor Sophie Scott (University College London), who provided a fascinating and rib-tickling insight into the psychology and neuroscience of laughter. The audience was soon in hysterics as Scott used the famous clip of cricket commentators Johnston and Agnew giggling, to show that laughter is a distinct, unmissable and universally recognised set of sounds that is highly infectious. She also talked us through the physical changes that happen as someone becomes quite literally helpless with laughter, for example how impossible it is to breathe or talk normally. But, she asked, what is the function and purpose of laughter? Scott believes that it is a social glue that binds us together – think of the joy of tickling a young baby and seeing them chuckle – and that it even gives us clues as to who we like and don’t like, for example, that dreaded colleague whose earnest jokes just never make you laugh. Her views on laughter were beautifully summarised by Victor Borge’s quote that ‘Laughter is the shortest distance between two people’.  

Next up, was Dr Mark Wetherell (Northumbria University) with his entertaining and informative take on the ways in which stress can be measured and manipulated (reprised from his talk at the 2011 North event: see tinyurl.com/lect2011). Professor Mick Cooper University of Strathclyde) then took the audience on a tour of how relational depth can be used in counselling. He invited the audience to think about what it is like to really feel connected to someone and discussed research that suggests this may be a useful way for a therapist to relate to their clients in therapy, stating that moments of deep connection in therapy are facilitated by a genuine warmth and openness and by
a commitment to engage deeply.

Lunch was followed by two hot topics sessions on what it’s like to study psychology, delivered by undergraduates, and then Professor Ulrike Hahn (Cardiff University) invited us to think about cognitive psychology: what it is and why it matters. Hahn provided a whole host of studies to convince the audience that it is almost impossible to learn something about human beings and not have some kind of immediate practical use for it. Her research dovetailed neatly into a hugely entertaining final talk from Professor Chris French (Goldsmiths, University of London), who began his talk by convincing all 700+ delegates that he could read their mind! He went on to explain how expectation and systematic bias can lead people to believe that paranormal forces are in action, particularly when we experience coincidences. For example, how many people do you think you would need to have at a party for there to be a 50:50 chance of two of them having the same birthday? In fact it is only 23. French then demonstrated the fallibility of memory by asking the audience what a number 4 looks like on a clock with Roman numerals – most said ‘IV’ but in fact for the vast majority it is ‘IIII’. He then gave us an intriguing set of examples of the brain seeing and hearing what it wants to hear, finishing with a clip of Led Zeppelin played backwards and showing us that with a bit of priming, gibberish can be made to sound like anything you want it to!

There was a fantastic level of engagement from the students throughout the whole day and some impressive and searching questions. I have no doubt that this year’s delegates went away with a richer understanding of what psychology has to offer the world.  

 

Dementia lottery?

Figures released by Alzheimer’s Society in January have revealed wide variations in how many people are receiving a diagnosis of dementia in Britain.

Based on population prevalence estimates from previous studies (see tinyurl.com/bks3avc), the charity estimates that there are 428,000 people in the UK who are living with the condition but who are not diagnosed. Diagnosis rates range from 31.6 per cent in East Riding of Yorkshire to 75.5 per cent in Belfast, and Alzheimer’s Society has produced an interactive map (www.alzheimers.org.uk/dementiamap) which highlights the number of people who have a diagnosis of dementia in different Primary Care Trusts in the UK.

To investigate the quality of assessment people with dementia are receiving, memory clinics in the UK were surveyed. Evidence indicated that just 11 per cent of clinics are accredited. The survey showed the average waiting time for an appointment is 32.5 working days, which is over the 4-6 weeks recommended by Memory Service National Accreditation Programme. Some memory clinics reported longer waiting times of up to nine months.

Jeremy Hughes, Chief Executive at Alzheimer’s Society, said: ‘It’s disgraceful that more than half of all people with dementia are not receiving a diagnosis, and disappointing to see such a disparity in diagnosis rates in different regions of the UK. This goes against best clinical practice and is preventing people with dementia from accessing the support, benefits and the medical treatments that can help them live well with the condition.’
