Fraud or scientific mistake?

Social psychology is reeling from its second research scandal in less than a year, after the Erasmus University of Rotterdam announced the withdrawal of two articles by one of its senior social psychologists. The problematic papers were identified by a ‘Committee for Inquiry into Scientific Integrity’ (chaired by Rolf Zwaan, a psychologist in the University’s Brain and Cognition lab), which was set up to investigate concerns raised about the work of Dirk Smeesters. Among the Inquiry’s recommendations was a call for greater regulation of the fields of marketing and ‘to a lesser extent’ social psychology.

Smeesters, who was Professor of Consumer and Society in the Rotterdam School of Management, was found guilty by the Inquiry of ‘data selection’ and failing to keep suitable data records. Smeesters resigned his post after admitting to using a ‘blue dot technique’ whereby, after achieving a null result, he omitted participants who failed to read the instructions properly (7 to 10 per study, he claims), thus lifting the findings into statistical significance – a procedure he failed to detail in his affected papers. However, Smeesters blamed the unavailability of his raw data on nothing more heinous than a computer crash and a lab move. The Inquiry said it ‘doubted the credibility’
of these reasons.

The affected papers pertained to social priming and past selves and
were published in the Journal of Personality and Social Psychology (tinyurl.com/bq32j9r), published by the APA, and the Journal of Experimental Social Psychology (tinyurl.com/c2nmxlh), published by Elsevier. A third affected paper had only reached the submission stage of publication.

The Inquiry found no evidence of wrong-doing by Smeesters’ co-authors, although there’s no doubt they are suffering from the fall-out (at least one of them has posted his feelings online: tinyurl.com/d53hndk).

These latest revelations come in the wake of the case of Diederik Stapel, a senior social psychologist at Tilburg University, who last year admitted to fabricating the results behind several dozen published studies (see News, December 2011). Smeesters has kept a low profile since the scandal broke,  but he surfaced late in June to tell the Dutch newspaper Algemeen Dagblad that he was ‘no Stapel’ – his data was not fabricated; he had made a scientific mistake. Stapel and Smeesters reportedly never worked together.

Concerns were first raised about Smeesters’ work by Uri Simonsohn,
a social psychologist at The Wharton School, University of Pennsylvania. Simonsohn has developed a statistical technique for detecting massaged data, details of which are contained in an as yet unpublished paper with the working title ‘Finding fake data: Four true stories, some stats, and a call for journals to post all data’ (criticisms of the technique have surfaced online: tinyurl.com/ccnymz6). Simonsohn contacted Smeesters requesting his raw data, and then he reported his findings to Smeesters’ head of school, which led ultimately to the Inquiry.

According to the Inquiry’s report (full English translation in pdf form at tinyurl.com/csjpxfr), Simonsohn’s technique identifies dubious data by looking at the amount of variation in the group means derived from the same population. With the aid of two statistical experts, the Erasmus University Inquiry applied Simonsohn’s algorithm to 22 of 29 papers published or submitted by Smeesters’ since 2007, for which the necessary data were available, which led to the identification of the three suspect papers (the technique was also applied to a random selection of four comparable control papers by others in the field and no anomalies were found).

Concerns were also raised about data anomalies in a fourth paper published by Smeesters and co-authors in the Journal of Consumer Research (tinyurl.com/crs8ehn). In relation to this paper, the Inquiry stated that it had found a file on Smeesters’ network desk that shouldn’t have been there based on his description of how the data were collected. The Inquiry states it ‘cannot rule out that Smeesters used the…file to manipulate the raw data before sending these’ to his data-analyst.

This isn’t the first time the whistleblower Simonsohn has taken an interest in research integrity. Last year he co-authored a paper ‘False-positive psychology’ in Psychological Science (tinyurl.com/canb33z; see News, January 2012), in which he and his colleagues demonstrated the ease with which false-positive results can be obtained by indulging in research practices that occupy a grey area of acceptability, such as adding more participants to a subject pool in search of a significant finding.

A paper published in May this year in Psychological Science (but detailed on our Research Digest blog last December: tinyurl.com/boynfxk) surveyed 6000 US psychologists about practices in this ‘grey zone’ and found that 58 per cent admitted excluding data post-hoc and 35 per cent had doubts about the integrity of their own research. Smeesters told the Inquiry that he doesn’t feel guilty because many authors in his field knowingly omit data to achieve significance.
Early in July, Simonsohn gave an interview to Nature (see tinyurl.com/7mtgawa) in which he claimed to have identified a third case of scientific misconduct that’s yet to be made official, and a fourth that’s not been acted upon. He said he was motivated to act in these cases by the fact that ‘it is wrong to look the other way’, but he stressed he hadn’t taken justice into his own hands – he was careful to pass things over to the appropriate authorities. ‘If it becomes clear that fabrication is not an unusual event,’ he said, ‘it will be easier for journals to require authors to publish all their raw data. It’s extremely hard for fabrication to go undetected if people can look at your data.’

Queen’s birthday honours for psychologists

Developmental psychologist and Society Fellow Professor Uta Frith of UCL and Aarhus University has been made an honorary Dame in the latest Foreign and Commonwealth Honours, for services to clinical science (the award is honorary because of Professor Frith’s German nationality).

Also recognised in the Queen’s Birthday Honours were Chartered Psychologist Anne Douglas, a Consultant Clinical Psychologist and Head of Trauma Services for NHS Greater Glasgow and Clyde, appointed OBE for services to the Health of Asylum Seekers and Refugees; Chartered Psychologist Melinda Edwards, a Consultant Clinical Paediatric Psychologist at St Thomas' Hospital, appointed MBE for services to children with chronic and life-threatening medical conditions; and Anne Moore, Chief Educational Psychologist at the London Borough of Croydon, who was appointed MBE for services to Special Needs Education.

Uta Frith is an internationally respected authority on autism and dyslexia, among other topics, and during her career she has mentored a small army of eminent researchers, including Professor Simon Baron-Cohen (Director of the Autism Research Centre at the University of Cambridge), Professor Francesca Happé (the newly appointed Director of the MRC Social, Genetic and Developmental Psychiatry Centre at the Institute of Psychiatry, KCL), and Professor Sarah-Jayne Blakemore (Leader of the Developmental Cognitive Neuroscience Group at the Institute of Cognitive Neuroscience, UCL), among many others.

In comments to the Society, Professor Frith paid tribute to her husband, the psychologist and BPS Fellow Chris Frith: ‘I often talk about how culture changes the brain,’ she said, ‘but I should really say that it is significant others who change the brain. In my case the significant other did so with such a delicacy and sensitivity that I never cease to
be grateful, and never cease to wonder at my good fortune.’

Anne Douglas told us she was ‘delighted’ with her honour, which ‘recognises the excellent work of the Compass team’ she heads in Glasgow. She added that all applied psychologists should be encouraged to take trauma histories from all clients as a matter of routine, and include it in their formulation and therapy plan. Together with Honorary Society Fellow Professor Bill Yule, Douglas is keen to establish a BPS Trauma Psychology section. ‘We need 1 per cent of the membership to get this off the ground,’ she said, ‘so if you are interested please vote at: www.bps.org.uk/traumasec’.

‘Delighted and extraordinarily humbled’ was how Melinda Edwards told us she felt on hearing of her award, especially after she learned she’d been nominated by the parents of young children she’s worked with. ‘These young people are members of “Evelina’s Pride”,
a supported youth group for young people with chronic and life-limiting medical conditions,’ Edwards said. The group was developed by Edwards nearly 15 years ago and aims to provide a ‘supportive peer network for young people, enabling fun and friendship through a range of inclusive social activities’.

‘I feel very privileged that our psychological skills give us the ability to assess in a more holistic way the needs of our patients and to provide appropriate help creatively in the most accessible way to support their development, adjustment and quality of life,’ Edwards added.

‘I feel even more privileged to have been a member of the Evelina Pride Group and to have been part of the lives of such inspirational young people.’

Anne Moore, who has worked for the London Borough of Croydon for 25 years, told us she feels ‘privileged’ to have worked with so many dedicated individuals during that time, and fortunate to have been part of a ‘very special team’ of educational psychologists, and to work for a council that has shown ‘tremendous support’ for special educational needs. ‘I am overwhelmed by this honour,’she said, ‘but thrilled to havethe opportunity to promote educational psychology to a wider audience. We extend congratulations to them all.

No extra benefit

Findings from a new randomised controlled trial suggest that adding facilitated exercise to standard care (including antidepressant medication) doesn’t bring any extra benefit to people with depression. ‘The main implication of our results is that advice and encouragement to increase physical activity is not an effective strategy for reducing symptoms of depression,’ the researchers said (British Medical Journal: tinyurl.com/brcey3a).

Psychologists app
A team of psychologists, led by Professor Robin Walker in the psychology department at Royal Holloway University of London, is working on an iPad app called ‘MDReader’, which it’s hoped will help people with macular degeneration, an eye condition that affects central vision. The app scrolls text in large font across the screen at a chosen speed, so that a reader can use peripheral vision whilst holding their gaze steady.

Wellcome image
A close-up photograph, taken during neurosurgery, of the surface of a living human brain is the overall winner of this year’s Wellcome Image Awards (see www.wellcomeimageawards.org), judged on technical merit as well as aesthetics. Alice Roberts of the judging panel said ‘Through the skill of the photographer [Robert Ludlow of UCL], we have the privilege of seeing something that is normally hidden away inside our skulls.’

Pain guidelines
With support and input from the British Psychological Society, the Royal College of Physicians has published new guidelines (tinyurl.com/cgl5jvm) for health professionals on complex regional pain syndrome – ‘a debilitating, painful condition in a limb associated with sensory, motor, autonomic, skin and bone abnormalities’. Chartered Health Psychologist Dr Helen Poole at Liverpool John Moores University was on the development panel.

Feeling in the brain
Christian Jarrett reports from a conference of the Association for the Scientific Study of Consciousness

What can neuroimaging tell us about human emotions that we don’t know already? The technology has come in for a lot of stick lately, with doubts raised about the field’s statistical methods and critics calling it the new phrenology. These doubters should have come to Tania Singer’s (Max Planck Institute for Human Cognitive and Brain Sciences in Germany) enthralling keynote lecture, on viewing emotions through the lens of social neuroscience.

Speaking at the Association for the Scientific Study of Consciousness, held in Brighton in July, Singer began by outlining a series of studies that looked at social factors affecting the way the brain responds to the sight of another person’s pain. For instance, using an economic game, Singer and her colleagues have shown that men, much more so than women, show a reduced pattern of empathy-related brain activity when they see pain inflicted on an opponent whom they judge to have played unfairly.

Group membership can also affect the brain’s empathic response. A study with fans of the football teams FC Zürich and FC Basel found that participants’ brains showed more empathy-related brain activity (in the insular cortex) to the sight of a member of their own football team being in pain, and in turn this was associated with a greater likelihood that they would agree to help that person by ‘sharing’ their pain. Singer has even uncovered the neural correlates of schadenfreude, finding evidence that reward-related activity in the nucleus accumbens is enhanced when a rival team player, or an unfair opponent in an economic game, is seen to be in pain.

Other studies have pinpointed a brain region that’s involved when we attempt to overcome what Singer calls our ‘egocentric bias’. These ingenious experiments involved contrasting the way a participant’s brain responded to the sight of another person being touched in an unpleasant way (for example, by a slimy slug), compared with when he or she (the participant) was touched simultaneously in a pleasant way by something fluffy. The latter scenario requires that the participant override their own tactile experience in order to empathise with the tactile experience of another. Overcoming egocentric bias in this way was associated with increased activity specifically in the right supramarginal gyrus (located on the parietal lobe), a finding that was confirmed by using transcranial magnetic stimulation to disrupt function in this area temporarily, the consequence of which was a five-fold increase in egocentricity.

Perhaps most fascinating of all were Singer’s forays into ways that the brain’s empathic response can be changed through training. For instance, when Singer scanned the brain of a monk looking at a person in pain, the pattern of neural activity he exhibited was unlike anything she’d ever seen, no doubt because he’s spent 30 years devoted to compassion-based meditation. Rather than feeling ‘as if’ he were experiencing their pain, he ‘felt for’ them, including seeing them as a meaningful other, and this was associated with activity in a distinct array of brain regions including the ventral striatum, medial orbito-frontal cortex and mid insula. Supporting this, studies with ordinary participants have shown that a day’s worth of empathy-based or compassion-based training leads to differences in the way the brain responds to another person’s pain: the former being associated with enhanced activation of classic empathy-related networks; the latter with areas similar to those that were activated in the monk.

‘The Zurich Prosocial Game’ – a videogame designed by Singer and her colleagues – has shown that short-term compassion training has behavioural consequences too, in terms of increased helping behaviour. Next, Singer plans to look at the long-term consequences, on brain and behaviour, of a year-long compassion training programme of 20 minutes per day. She’s also looking at the contrasting subjective experiences of empathy and compassion. Her volunteer monks say the main difference is warmth – that is, compassion feels warmer. Writing from the perspective of a rainy British July, perhaps if we all worked to be more compassionate, we could finally get this summer started!

Playing with body ownership

The sense that our bodies belong to us seems so instinctive and immutable, but psychologists using illusions are exposing this to be a fallacy. With toy-shop props and virtual-reality sets, participants have been led to believe they’ve had sensations in a rubber arm, shrunken bodies and even out-of-body experiences. In a gripping talk, Manos Tsakiris (Royal Holloway, University of London) described how he’s extended this line of work, including conducting fascinating experiments looking at how sense of body ownership is weaker in some people (e.g. those with anorexia) than others.

A consistent finding in this research is that heart-rate sensitivity appears to be a useful proxy for strength of body ownership. Consider a task in which a participant looks at a strange face in a computer monitor, and whenever the participant is stroked on his or her face, the face on the monitor is stroked in synchrony, in exactly the same place, almost as if the participant is looking into a mirror, but it’s a stranger’s face looking back rather than their own. Tsakiris has morphed the face to look increasingly like the participant and asked him or her to indicate at which point the face in monitor feels like it is them. People who are poorer at detecting their own heart rate (i.e. they have low ‘interoceptive awareness’) tend to say that they feel ownership of the monitor face sooner.

Moreover, these studies have shown that the effect of congruent touching (of their own and the monitor face) has a much more powerful effect on people with low interoceptive awareness. In a particularly dramatic demonstration of this effect, Tsakiris and his colleagues made it so that the face in the monitor appeared to be sliced down the cheek with a blade of glass. People with poor heart-rate sensitivity showed greater skin-conductance response to this sight, providing further evidence that they find it easier to feel a sense of ownership over that face.

Intriguingly, Tsakiris’ studies have also shown that interoceptive awareness can be manipulated. For example, a person who’s usually poor at feeling their own heart beat, improves when they look at themselves in the mirror, or even if they simply look at words that are self-relevant. There are social effects too – children with low interoceptive awareness become more aware of their hearts when in the company of their parents.

Tsakiris is planning a range of exciting extensions to this work, including experiments to look at the effects of other relationships on interoceptive awareness, such as the presence of a partner, and also the part that attachment styles might play.

From the ASSC posters
Prejudices can influence our raw perceptions. Yaïr Pinto and his colleagues at the University of Amsterdam set up a binocular rivalry experiment in which a fading Mondrian pattern was presented
to one eye and a racially black or white face, growing in visibility, was presented simultaneously to the other (rather than blending, this situation leads to the conscious perception of one or other of the images). Participants became consciously aware of black faces later than white faces. The finding was also replicated, with Moroccan faces reaching awareness later than Dutch faces.

What’s it like to wear prism glasses that invert the visual scene from left to right? Jan Degenaar at the University of Antwerp has documented the subjective experience of adaptation, based on wearing the glasses for four hours per day for 31 days. It took him 57 hours to regain the ability to grasp objects and a full 123 hours for objects to appear to him to be located in their real locations. However, even after successful adaptation, his experience of the world still felt qualitatively different from normal vision.

Evidence on the emotional content of dreams is a mixed bag, in terms of the amount and valence of what’s been found in different studies. According to Pilleriin Sikka and her colleagues at the University of Turku, this is because of methodological differences. Sikka’s team compared dream diaries, self-rating of dream content and observer-ratings of dream content (based on a woken participant freely recalling a dream and a researcher coding the content). Dreams were found to be more emotional and more positive when self-rated compared with observer-rated, casting doubt on the convergent validity of subjective and objective measures.

Past research has pointed to synaesthesia – the mixing of sensory experiences – being associated with superior memory performance, but the precise forms of memory affected have not been clarified. Nicolas Rothen and his colleagues at the University of Sussex compared dozens of grapheme-colour synaethetes (for whom letters reliably evoke certain colours) with normal controls and found that the synaethetes showed superior performance on recognition memory and short-term memory (perhaps because of their richer sensory experiences), but not iconic memory. 

Psychology vs. literature

Karen Goodall (Queen Margaret University, Edinburgh) listened to the debate

‘Who understands the human mind better: Psychologists or crime writers? This was the theme of a free public event organised by the Society’s Scottish branch, which took place on 21 June 2012 at the Royal College of Surgeons in Edinburgh.

Despite the summer downpour the venue was full, a testament to the popularity of the speakers: best-selling novelist Ian Rankin and psychologist Professor Richard Wiseman. Rankin, arguably Scotland’s best crime writer, is author of 33 titles, including the hugely popular Inspector Rebus series. He recently received the OBE for services to literature. Wiseman researches the psychology of luck, self-help, persuasion and illusion, and is the most followed UK psychologist on Twitter. His bestselling books have been translated into over 30 languages and he was named one of the top 100 people who make Britain a better place to live.

Prior to the event, Dr Elizabeth Hannah, a Chartered Psychologist and Honorary Secretary of the Branch, commented: ‘Ian’s Rebus novels provide real insight into the human mind, so it will be interesting to see who the audience feels has the better understanding. As a psychologist, I have high hopes for Richard!’

The evening started on a lighthearted note, with Rankin, who is currently finishing his 18th Inspector Rebus novel, admitting that he might have finished his final draft, had he not committed to the event. For the audience, it was a worthwhile sacrifice as the unscripted conversation between Rankin and Wiseman provided a unique insight into the overlap between psychological understandings of the human mind and the writer’s craft.

Topics that were explored included the function of novels in imposing order on an often chaotic and unfathomable world, for both writer and reader. Rankin illustrated this by recounting the feelings of helplessness and incomprehension he experienced when his younger son was diagnosed with a rare genetic disorder. He noted that writing alleviated his distress and allowed him to ‘play God’. He was told that his son would never walk; Rebus’ daughter was then subjected to an accident which left her in a wheelchair, although she later regained use of her legs as Rankin admitted that he ‘felt a bit mean’!

Literature, as a way of ‘trying on other guises’ was explored. Rankin admitted to enjoying ‘acting as Rebus’, as the physical and confrontational character of Rebus is the antithesis of his own personality. Wiseman pondered whether literature is a way of enabling readers to explore darker aspects of their personality in safety, which led to a discussion of the complexity of evil.

Rankin recounted his conversations with prisoners on death row in America whilst researching his television series Ian Rankin’s Evil Thoughts. He noted the relative ease with which we can feel an empathic response towards an individual during face-to-face interaction, whilst the ‘cognitive part of the brain’ simultaneously baulks at the severity of the crimes they have committed.

Empathy as a bridge between minds was proposed as a key element in literature, for both the reader and novelist with Rankin discussing how characters come alive only when both the reader and writer feel empathy towards that character. After an enlightening 90 minutes the audience was left with a strong impression of the interface between psychology and literature. Who won the debate? The jury is still out as Rankin and Wiseman’s skillful handling of the topic opened up further questions to be pondered as we filed back out into the rain. A rematch has been promised though, so watch this space!

Heroin role

A new report from the NHS National Treatment Agency for Substance Misuse has documented the systemic changes that need to be made to help heroin addicts in England overcome their dependence on ‘opioid substitution treatment’ (OST), such as methadone. At present about 150,000 heroin addicts in the country are on a substitute medication, and whilst effective as an initial treatment, there are concerns that many remain on these drugs indefinitely.

‘It is not acceptable,’ the report says, ‘to leave people on OST without actively supporting their recovery and regularly reviewing the benefits of their treatment (as well as checking, responding to, and stimulating their readiness for change)’. A key facet of the approach endorsed by the report is for psychosocial support to be adapted to each client’s individual needs: for example, making use of peer role models, self-help groups, employment support and couples or family therapy (where the family member is a non-user).

Several psychologists were members of the Recovery Oriented Drug Treatment Expert Group that compiled the new recommendations, including: Chartered Clinical Psychologist and BPS Associate Fellow Professor Alex Copello, a consultant at Birmingham University; Chartered Clinical Psychologist Dr Luke Mitcheson, a consultant at the NHS National Treatment Agency for Substance Misuse; and Chartered Clinical Psychologist Dr Stephen Pilling, Director of the National Collaborating Centre for Mental Health.

Dr Mitcheson told us that psychologists should have a central leadership role in helping to challenge the English commissioning and treatment system to ensure that psychological treatments are available and used by service users. ‘This report should lead to opportunities for psychologists to design programmes as well as provide training and supervision of staff,’ he said. ‘The goal is to recalibrate the system to one that is more psychologically informed and focused on client outcomes.’
