"Anyone considering, or already studying psychology will have to learn about and understand research methods and statistics. The fact that research methods and statistics is nearly always compulsory should immediately alert you to its importance. In order to critcally evaluate the findings of key studies you need to be aware of how the data supporting those findings came about; and you can't seriously hope to conduct your own research with confidence unless you have a clear idea how to design, execute and analyse your investigation. When I first started supervising research dissertations and psychology projects I came across a large number of students who refused to consider doing anything other than indepth interviews, whether such an approach was appropriate for their particular invesigation or not. The most common reason for this was the incorrect assumption that qualitative research methods (text based) are much easier to understand and carry out proficiently than Quantitative (number based) research methods.

"The research, reported online in the journal Legal and Criminological Psychology, could lead to new tools for diagnosis and treatment, and perhaps have applications in law enforcement. "Our paper is the first to show that you can use automated tools to detect the distinct speech patterns of psychopaths," says Jeff Hancock, professor of communication at Cornell University. This can be valuable to clinical psychologists, because the approach to treatment of psychopaths can be very different. Straight from the Source Read the original study DOI: 10.1111/j.2044-8333.2011.02025.x Researchers compared stories told by 14 imprisoned psychopathic male murderers with those of 38 convicted murderers who were not diagnosed as psychopathic. Each subject was asked to describe his crime in detail; the stories were taped, transcribed, and subjected to computer analysis. A psychopath, as described by psychologists, is emotionally flat, lacks empathy for the feelings of others, and is free of remorse. Psychopaths behave as if the world is to be used for their benefit, and they employ deception and feigned emotion to manipulate others. The words of the experimental subjects matched these descriptions. Psychopaths used more conjunctions like "because," "since" or "so that," implying that the crime "had to be done" to obtain a particular goal. They used twice as many words relating to physical needs, such as food, sex, or money, while non-psychopaths used more words about social needs, including family, religion, and spirituality. Psychopaths are predators and their stories often include details of what they had to eat on the day of their crime, writes co-author Michael Woodworth, associate professor of psychology at the University of British Columbia. Psychopaths were more likely to use the past tense, suggesting a detachment from their crimes-and tended to be less fluent in their speech, using more "ums" and "uhs." Researchers speculate that the

"Henri Tajfel's interest in identity and group prejudice was sparked by his own experiences as a Polish Jew during the Second World War. As Professor of Social Psychology at Bristol university he developed a series of experiments known as the Minimal Group Studies, the purpose of which was to establish the minimum basis on which people could be made to identify with their own group and show bias against another. Claudia Hammond re-visits the Minimal Group Studies of 1971, where Tajfel and his collaborators got boys at a comprehensive school to view abstract paintings and then assigned them to the 'Klee' group or the 'Kandinsky' group, apparently because of the preferences they declared, but in fact entirely at random. Even though the boys didn't know who else was allocated to their group, they consistently awarded more points to their own group than to the other. So even though who belonged to which group was meaningless, they always tended to favour their own. This proved to be the first step towards Social Identity Theory, as developed by Henri Tajfel and John Turner, which stressed that our identification with groups varies according to how significant that group is at the time: if we're at war our national identity is important, at a football match it's our team identity that's to the fore... Tajfel died in 1982, but his legacy can be seen in the work many of his former students continue in the same field. Claudia Hammond hears from four of them, including Michael Billig - Professor of Social Sciences at Loughborough University, who helped run the 1971 studies, Miles Hewstone, Rupert Brown and Steve Reicher, Professors of Social Psychology at Oxford, Sussex and St Andrews respectively."

"FOR a brief, heady period in the history of autism spectrum diagnosis, in the late '90s, I had Asperger syndrome. There's an educational video from that time, called "Understanding Asperger's," in which I appear. I am the affected 20-year-old in the wannabe-hipster vintage polo shirt talking about how keen his understanding of literature is and how misunderstood he was in fifth grade. The film was a research project directed by my mother, a psychology professor and Asperger specialist, and another expert in her department. It presents me as a young man living a full, meaningful life, despite his mental abnormality. "Understanding Asperger's" was no act of fraud. Both my mother and her colleague believed I met the diagnostic criteria laid out in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The manual, still the authoritative text for American therapists, hospitals and insurers, listed the symptoms exhibited by people with Asperger disorder, and, when I was 17, I was judged to fit the bill. I exhibited a "qualified impairment in social interaction," specifically "failure to develop peer relationships appropriate to developmental level" (I had few friends) and a "lack of spontaneous seeking to share enjoyment, interests, or achievements with other people" (I spent a lot of time by myself in my room reading novels and listening to music, and when I did hang out with other kids I often tried to speak like an E. M. Forster narrator, annoying them). I exhibited an "encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus" (I memorized poems and spent a lot of time playing the guitar and writing terrible poems and novels). The general idea with a psychological diagnosis is that it applies when the tendencies involved inhibit a person's ability to experience a happy, normal life. And in my c

"ACCORDING to Joseph Henrich and his colleagues at the University of British Columbia, most undergraduates are WEIRD. Those who teach them might well agree. But Dr Henrich did not intend the term as an insult when he popularised it in a paper published in Behavioral and Brain Sciences in 2010. Instead, he was proposing an acronym: Western, Educated, Industrialised, Rich and Democratic. One reason these things matter is that undergraduates are also psychology's laboratory rats. Incentivised by rewards, in the form of money or course credits, they will do the human equivalents of running mazes and pressing the levers in Skinner boxes until the cows come home. Which is both a blessing and a problem. It is a blessing because it provides psychologists with an endless supply of willing subjects. And it is a problem because those subjects are WEIRD, and thus not representative of humanity as a whole. Indeed, as Dr Henrich found from his analysis of leading psychology journals, a random American undergraduate is about 4,000 times more likely than an average human being to be the subject of such a study. Drawing general conclusions about the behaviour of Homo sapiens from the results of these studies is risky. This state of affairs, though, may be coming to an end. The main reasons undergraduates have been favoured in the past are that they are cheap, and easy for academics to recruit. But a new source of supply is now emerging: crowdsourcing."

"Fear can distort our perceptions, psychological research indicates, and creepy-crawly spiders are no different. People who are afraid of spiders see the arachnids as bigger than they actually are, recent experiments have shown. Researchers asked people who had undergone therapy to address their fear of spiders to draw a line representing the length of a tarantula they had just encountered in a lab setting. "On average, the most fearful were drawing lines about 50 percent longer than the least fearful," said Michael Vasey, lead study researcher and professor of psychology at Ohio State University. "We have seen participants draw lines that are at least three times as long as the actual spider." [What Scares You? (Infographic)] After undergoing exposure therapy - in which people confront something they fear, in this case, spiders - 57 people with spider phobia were given the task of approaching a spider in an aquarium, then using a 4-inch (10.2 centimeter) probe to nudge it around the tank. They repeated this encounterfive times with different species of spider over eight weeks. "

"Despite memory's obvious benefits, it can also let us down, said Daniel Schacter, PhD, longtime memory researcher and chair of Harvard University's psychology department, at an APA 2003 Annual Convention session honoring the publication of his book, "The Seven Sins of Memory: How the Mind Forgets and Remembers" (Houghton Mifflin, 2001). "Memory, for all that it does for us every day...for all the feats that can sometimes amaze us, can also be a troublemaker," said Schacter of his book, which describes the seven major categories of memory foibles being investigated by psychologists. However, noted Schacter, the same brain mechanisms account for memory's sins as well as its strengths, so investigating its negatives exposes its positives. "We shouldn't think of these fundamentally as flaws in the architecture of memory," he explained, "but rather as costs we pay for benefits in memory that make it work as well as it does most of the time." At the session, during which Schacter received the APA Div. 1 (Society for General Psychology) William James Book Award, he defined his book's seven sins. The first three are "sins of omission" that involve forgetting, and the second four are "sins of commission" that involve distorted or unwanted recollections."

"For a hormone, oxytocin is pretty famous. It's the "cuddle chemical" -- the hormone that helps mothers bond with their babies. Salespeople can buy oxytocin spray on the internet, to make their clients trust them. It's known for promoting positive feelings, but more recent research has found that oxytocin can promote negative emotions, too. The authors of a new review article in Current Directions in Psychological Science, a journal of the Association for Psychological Science, takes a look at what oxytocin is really doing."

"Scientists who scanned the brains of men convicted of murder, rape and violent assaults have found the strongest evidence yet that psychopaths have structural abnormalities in their brains. The researchers, based at King's College London's Institute of Psychiatry, said the differences in psychopaths' brains mark them out even from other violent criminals with anti-social personality disorders (ASPD), and from healthy non-offenders. Nigel Blackwood, who led the study, said the ability to use brain scans to identify and diagnose this sub-group of violent criminals has important implications for treatment. The study showed that psychopaths , who are characterised by a lack of empathy, had less grey matter in the areas of the brain important for understanding other peoples' emotions. While cognitive and behavourial treatments may benefit people with anti-social personality disorders, the same approach may not work for psychopaths with brain damage, Blackwood said. "To get a clear idea of which treatments are working, you've got to clearly define what people are like going into the treatment programmes," he said in a telephone interview. Essi Viding a professor in the psychology and language sciences department of University College London, who was not involved in Blackwood's study, said it provided "weighty new evidence" about the importance of distinguishing psychopathic from non-psychopathic people rather than grouping them together. The findings also have implications for the justice system, because linking psychopathy to brain function raises the prospect of arguing a defence of insanity. Interest in what goes on inside the heads of violent criminals has been sharpened by the trial of Anders Behring Breivik, the Norwegian who massacred 77 people last July. Two court-appointed psychiatric teams who examined Breivik came to opposite conclusions about his mental health. The killer himself has railed being called insane."

"MID the squawks and pings of our digital devices, the old-fashioned virtues of reading novels can seem faded, even futile. But new support for the value of fiction is arriving from an unexpected quarter: neuroscience. Brain scans are revealing what happens in our heads when we read a detailed description, an evocative metaphor or an emotional exchange between characters. Stories, this research is showing, stimulate the brain and even change how we act in life. Researchers have long known that the "classical" language regions, like Broca's area and Wernicke's area, are involved in how the brain interprets written words. What scientists have come to realize in the last few years is that narratives activate many other parts of our brains as well, suggesting why the experience of reading can feel so alive. Words like "lavender," "cinnamon" and "soap," for example, elicit a response not only from the language-processing areas of our brains, but also those devoted to dealing with smells. In a 2006 study published in the journal NeuroImage, researchers in Spain asked participants to read words with strong odor associations, along with neutral words, while their brains were being scanned by a functional magnetic resonance imaging (fMRI) machine. When subjects looked at the Spanish words for "perfume" and "coffee," their primary olfactory cortex lit up; when they saw the words that mean "chair" and "key," this region remained dark. The way the brain handles metaphors has also received extensive study; some scientists have contended that figures of speech like "a rough day" are so familiar that they are treated simply as words and no more. Last month, however, a team of researchers from Emory University reported in Brain & Language that when subjects in their laboratory read a metaphor involving texture, the sensory cortex, responsible for perceiving texture through touch, became active. Metaphors like "The singer had a velvet vo

Samuel Beckett, born in a suburb of Dublin in 1906, was a native English speaker. However, in 1946 Beckett decided that he would begin writing exclusively in French. After composing the first draft in his second language, he would then translate these words back into English. This difficult constraint - forcing himself to consciously unpack his own sentences - led to a burst of genius, as many of Beckett's most famous works (Malloy, Malone Dies, Waiting for Godot, etc.) were written during this period. When asked why he wrote first in French, Beckett said it made it easier for him to "write without style." Beckett would later expand on these comments, noting that his use of French prevented him from slipping into his usual writerly habits, those crutches of style that snuck into his English prose. Instead of relying on the first word that leapt into consciousness - that most automatic of associations - he was forced by his second language to reflect on what he actually wanted to express. His diction became more intentional. There's now some neat experimental proof of this Beckettian strategy. In a recent paper published in Psychological Science, a team of psychologists led by Boaz Keysar at the University of Chicago found that forcing people to rely on a second language systematically reduced human biases, allowing the subjects to escape from the usual blind spots of cognition. In a sense, they were better able to think without style. The paper is a tour de force of cross-cultural comparison, as the scientists conducted six experiments on three continents (n > 600) in five different languages: English, Korean, French, Spanish and Japanese. Although all subjects were proficient in their second language, they were not "balanced bilingual." The experiments themselves relied on classic paradigms borrowed from prospect theory, in which people are asked to make decisions under varying conditions of uncertainty and risk. For instance, native English

"One day last summer, Anne and her husband, Miguel, took their 9-year-old son, Michael, to a Florida elementary school for the first day of what the family chose to call "summer camp." For years, Anne and Miguel have struggled to understand their eldest son, an elegant boy with high-planed cheeks, wide eyes and curly light brown hair, whose periodic rages alternate with moments of chilly detachment. Michael's eight-week program was, in reality, a highly structured psychological study - less summer camp than camp of last resort. Michael's problems started, according to his mother, around age 3, shortly after his brother Allan was born. At the time, she said, Michael was mostly just acting "like a brat," but his behavior soon escalated to throwing tantrums during which he would scream and shriek inconsolably. These weren't ordinary toddler's fits. "It wasn't, 'I'm tired' or 'I'm frustrated' - the normal things kids do," Anne remembered. "His behavior was really out there. And it would happen for hours and hours each day, no matter what we did." For several years, Michael screamed every time his parents told him to put on his shoes or perform other ordinary tasks, like retrieving one of his toys from the living room. "Going somewhere, staying somewhere - anything would set him off," Miguel said. These furies lasted well beyond toddlerhood. At 8, Michael would still fly into a rage when Anne or Miguel tried to get him ready for school, punching the wall and kicking holes in the door. Left unwatched, he would cut up his trousers with scissors or methodically pull his hair out. He would also vent his anger by slamming the toilet seat down again and again until it broke. When Anne and Miguel first took Michael to see a therapist, he was given a diagnosis of "firstborn syndrome": acting out because he resented his new sibling. While both parents acknowledged that Michael was deeply hostile to the new baby, sibling rivalr

"Witness testimony has been the gold standard of the criminal justice system, revered in courtrooms and crime dramas as the evidence that clinches a case. Yet scientists have long cautioned that the brain is not a filing cabinet, storing memories in a way that they can be pulled out, consulted and returned intact. Memory is not so much a record of the past as a rough sketch that can be modified even by the simple act of telling the story. For scientists, memory has been on trial for decades, and courts and public opinion are only now catching up with the verdict. It has come as little surprise to researchers that about 75 percent of DNA-based exonerations have come in cases where witnesses got it wrong. This month, the Supreme Court heard its first oral arguments in more than three decades that question the validity of using witness testimony, in a case involving a New Hampshire man convicted of theft, accused by a woman who saw him from a distance in the dead of night. And in August the New Jersey Supreme Court set new rules to cope with failings in witness accounts, during an appeal by a man picked from a photo lineup, and convicted of manslaughter and weapons possession in a 2003 fatal shooting. Rather than the centerpiece of prosecution, witness testimony should be viewed more like trace evidence, scientists say, with the same fragility and vulnerability to contamination. Why is a witness's account so often unreliable? Partly because the brain does not have a knack for retaining many specifics and is highly susceptible to suggestion. "Memory is weak in eyewitness situations because it's overloaded," said Barbara Tversky, a psychology professor at Columbia University's Teachers College in New York. "An event happens so fast, and when the police question you, you probably weren't concentrating on the details they're asking about." "

"The decision by New Jersey's Supreme Court last week to overhaul the state's rules for how judges and jurors treat evidence from police lineups could help transform the way officers conduct a central technique of police work, criminal justice experts say. In its ruling, the court strongly endorsed decades of research demonstrating that traditional eyewitness identification procedures are flawed and can send innocent people to prison. By making it easier for defendants to challenge witness evidence in criminal cases, the court for the first time attached consequences for investigators who fail to take steps to reduce the subtle pressures and influences on witnesses that can result in mistaken identifications. "No court has ever taken this topic this seriously or put in this kind of effort," said Gary L. Wells, a professor of psychology at Iowa State University who is an expert on witness identification and has written extensively on the topic. Other courts are likely to follow suit, and in November the United States Supreme Court will take up the question of identification for the first time since 1977. But changing how the nation's more than 16,000 independent law enforcement agencies handle the presentation of suspects to witnesses will be no easy task, many experts say."

"Jerome Kagan's "Aha!" moment came with Baby 19. It was 1989, and Kagan, a professor of psychology at Harvard, had just begun a major longitudinal study of temperament and its effects. Temperament is a complex, multilayered thing, and for the sake of clarity, Kagan was tracking it along a single dimension: whether babies were easily upset when exposed to new things. He chose this characteristic both because it could be measured and because it seemed to explain much of normal human variation. He suspected, extrapolating from a study he had just completed on toddlers, that the most edgy infants were more likely to grow up to be inhibited, shy and anxious. Eager to take a peek at the early results, he grabbed the videotapes of the first babies in the study, looking for the irritable behavior he would later call high-reactive.

She was distressed by novelty - new sounds, new voices, new toys, new smells - and showed it by flailing her legs, arching her back and crying. Here was what Kagan was looking for but was not sure he would find: a baby who essentially fell apart when exposed to anything new. Baby 19 grew up true to her temperament. This past summer, Kagan showed me a video of her from 2004, when she was 15. We sat in a screening room in Harvard's William James Hall - a building named, coincidentally, for the 19th-century psychologist who described his own struggles with anxiety as "a horrible dread at the pit of my stomach ... a sense of the insecurity of life." Kagan is elfin and spry, ba

"FOR the last few weeks, the sex abuse scandal at Penn State and the harassment claims against the Republican presidential candidate Herman Cain have been fodder for discussion at my house. The same is true, I assume, around the country. Putting aside the specifics of each case, one question that has come up is, "What would I do?" That is, if I saw what seemed to be a crime or unethical act committed by a respected colleague, coach, teacher or friend, would I storm in and stop it? Would I call the authorities immediately? Would I disregard the potentially devastating impact on my job or workplace or beloved institution? Absolutely, most of us would probably reply. I think so, others might respond. And the most honest answer? I don't know. As much as we would like to think that, put on the spot, we would do the right - and perhaps even heroic - thing, research has shown that that usually isn't true. "People are routinely more willing to be critical of others' ethics than of their own," said Francesca Gino, an associate professor at Harvard Business School, and two other authors in the journal article "See No Evil: When We Overlook Other People's Unethical Behavior." The article appeared as a chapter in the book "Social Decision Making" (Psychology Press, 2009). "People believe they are more honest and trustworthy than others and they try harder to do good." But our faith in ourselves isn't borne out by history or research, something the Times columnist David Brooks pointed out in his column this week. The most well-known example of this in academia is the experiment conducted by the Yale University psychologist Stanley Milgram in the early 1960s. In the experiment, participants were "teachers" and, unbeknown to the participants, the "learner" was really an actor. The teacher was to instruct the learner in word pairs. For every wrong answer, the teacher could shock the learner, increasing the intensity of the shock for

We humans are such complex beasts. Why is it that we can be so wonderful and yet so awful, eccentric and prosaic, enigmatic and obvious, witty and dull, and all of these at once? All in the Mind, presented by Natasha Mitchell, is Radio National's weekly foray into all things mental - a program about the mind, brain and behaviour. From dreaming to depression, addiction to artificial intelligence, consciousness to coma, psychoanalysis to psychopathy, free will to forgetting - All in the Mind explores the human condition through the mind's eye. Our mental machinery remains one of the greatest mysteries of this or any other age, performing for us the most incredible feats of perception, cognition and coordination. Scientists, theologians, philosophers and armchair psychologists alike have long debated its form and function. And yet, the mind, in all its madness and brilliance, continues to elude us. All in the Mind brings together unexpected voices, themes and ideas and engages with both leading thinkers and personal stories. Psychology and human behaviour are only part of the equation. The program's scope is considerably broader and explores themes in science, religion, health, philosophy, education, history and pop culture, with the mind as the key focus.

"A MOTHER sits in a playroom with her young son. The phone rings. When she picks it up, a researcher watching through a two-way mirror asks her to look into her son's eyes and ''show him, in the way that feels most natural for you, that you love him''. The mother is doing her best to connect, but this little boy won't return her gaze. He looks at her mouth, where the words are coming from, but it's as if he can't understand what she means.

Mark Dadds says some children literally cannot see the love in their mother's eyes. Professor Dadds, a parenting expert from the University of New South Wales, has just published results of his work in the British Journal of Psychiatry and the Journal of Child Psychiatry and Psychology that suggest the ability to make eye contact is vital in learning how to love other people. For the past five years, he has been working with children referred to his Sydney clinic for sustained rages, continual aggression, calculated violence and, occasionally, cruelty to animals. These are children with some of the worst behavioural problems, who score highly for ''callous, unemotional'' traits. In his studies in both Sydney and London, it was these children who did not meet their mother's gaze, even when told they were loved. People marvel at the resilience of children who overcome appalling family backgrounds to make good lives. We understand when childhood trauma sends a child off the rails. But we also have to accept that even good parents can have mean children - how else to explain families where only one child seems to be callous and unemotional, while the siblings are not? Dadds distinguishes between children who are emotionally ''hot'' - those who lash out at the world - and the much smaller subset of ''cold'' children - the ones who don't react emotionally, don't car

"It is unusual for the subtitle of a book to undersell it, but Steven Pinker's "Better Angels of Our Nature" tells us much more than why violence has declined. Pinker, a professor of psychology at Harvard who first became widely known as the author of "The Language Instinct," addresses some of the biggest questions we can ask: Are human beings essentially good or bad? Has the past century witnessed moral progress or a moral collapse? Do we have grounds for being optimistic about the future?"
