Untattoo You

What happens when you cross the Avon Lady with a Neo-Nazi murder defendant?

Guest essay by Sam Sommers*

Several colleagues and students forwarded to me this story from the NY Times describing a criminal defendant in Florida whose attorney successfully petitioned the court to pay for a cosmetologist to help him cover up his swastika tattoos with makeup before trial each morning. The basis for the request was the defense's (quite reasonable) concerns that jurors would have a hard time remaining impartial as they sat in judgment of someone adorned by Neo-Nazi symbols.


The case raises a wide range of interesting questions involving the psychology of law, physical appearance, first impressions, and daily interaction–the very issues often at the heart of this blog. Questions such as:

Should the court have agreed? 

While the unusual nature of the request is what has rendered it newsworthy, similar issues arise in a wide range of cases. Defendants often change clothes before entering court in order to prevent them from having to appear in front of the jury in a prison jumpsuit. Similarly, defendants in custody may be unshackled outside of the presence of the jurors so as to avoid undue bias.

The question becomes, though, should such accommodation apply to tattoos? After all, the defendant in the Florida case presumably chose to decorate himself in Neo-Nazi images. Should the taxpayers foot the bill to cover up decisions that the defendant made of his own free will? Moreover, the prosecution alleges that the attacks in question were motivated by hate: one assault victim was attacked allegedly for associating with a Black man; the homicide victim was gay. Reactions to the case might be different had the defendant gotten the tattoos earlier in life and long since forsworn the ideology associated with them. This wasn't the case here.

Can the issue be reframed? 

Many people I've spoken with have suggested, as alluded to above, that since the defendant chose these tattoos, he should be stuck with the repercussions of that decision. But the issue becomes more complex when you consider that the question for the court was not simply whether the defendant should be allowed to cover his tattoos, but rather whether the court would pay for it. Because a tattooed defendant with the money for his own removal/cover-up would be free to do as he wished.

Most people I've talked to have trouble with the idea that the court would pay for a Neo-Nazi charged with hate crimes to cover up swastika tattoos. But when the same question is reframed, most of the same people agree that a poor defendant charged with capital crimes should be entitled to just as vigorous a defense as a wealthier defendant in the same situation. Pitched this way, the issue becomes more complicated.

Couldn't the judge just remind the jurors to stick to the evidence and ignore the defendant's appearance? 

Sure. And as the division director for the Florida attorney's office argues in the Times article, "We believe the jurors listen to judges' instructions."

But while I have no doubt that jurors often try to follow the rules they're given, examples to the contrary abound. For instance, years ago I published a few research studies indicating that evidence still impacts a jury even after it has been ruled inadmissible. Moreover, judicial instructions to avoid prejudice or partiality have not been sufficient to eliminate other forms of disparity, such as the increased likelihood that a defendant in a capital trial will be sentenced to death when his victim is White as opposed to non-White.

It remains the case that sometimes jurors decide they'd rather not hew to the letter of the judge's instructions. And other times, jurors aren't even aware in the first place of the biases that they're supposed to be avoiding.

If this defendant gets money to change how he looks, what about other defendants similarly disadvantaged by appearance? No good legal debate is complete without the proverbial slippery slope argument, so where do we go from tattoo guy? Should relatively unattractive defendants be allowed to ask for makeovers? Given stereotypes about overweight individuals and self-control, what about an obese defendant in a negligence case? Clearly, the slope isn't so slippery as to allow a defendant from a traditionally disadvantaged minority group to appear in court in whiteface, but where should the line be drawn?

When symphony orchestras wanted to reduce bias in the hiring of musicians, they had candidates audition behind a screen so that gender was not apparent. Accordingly, one of my students in class last week asked, why not do the same to mask the demographics and background of a criminal defendant? Not a proposal that you're likely to see anytime soon in a courtroom near you, but interesting fodder for discussion nonetheless.

So I now turn the question to you, dear readers... Court-sponsored tattoo cover-ups: misguided use of public funds or necessary protection of defendant rights?

Arizona rampage: Analyzing the analyzers

It's an endless loop tape, spinning us in a vortex of irrationality so all-encompassing it almost starts to seem normal.

After every high-profile crime, experts charge out of their corners with their pet solutions: Restrict high-capacity gun magazines. Increase mental health services. Revise school or workplace procedures.

Conservative media psychiatrist Sally Satel is even using the Arizona tragedy as a platform for laws requiring schools and businesses to report to authorities any student or employee who it "ejects or otherwise removes …. out of concern about behavior and dangerousness." Talk about a civil liberties nightmare!

Memorial crime control


Such opportunistic crime-control advocacy works best during moments of public crisis. When the hysteria reaches critical mass, politicians appease anxious constituencies through yet another feel-good law. Then, the latest crisis dies down and people get back to their normal lives. Watching Fox-TV, they remain blissfully shielded from the dark side of memorial crime control.

Rather than capturing the monsters of the public's imagination -- lunatic rampagers, sexual predators, and homicidal gangsters -- this inexorable web of draconian laws ends up ensnaring the most vulnerable, mainly young African American and Latino men from poor communities.

Do you recognize the name Rodrigo Caballero? Unlikely. He is just one tiny speck in a mass of captive and unknown dark bodies, a 16-year-old mentally ill California boy sentenced to 110 years in prison for attempted murder. Any cathartic efforts of memorial crime control are short-lived, while the costly and unanticipated social costs live on. Young Mr. Caballero isn't due out of prison until 2110, long after he and all of the rest of us will be dead.

No profile of would-be assassins

There will always be the next rare event to fuel this cycle of knee-jerk response, ostensibly aimed at protecting us from every remote contingency. Hindsight bias is a powerful heuristic that obscures an unfortunate truth: It is very hard to accurately predict -- much less prevent -- individual-level violence. As I wrote four years ago, after Cho Seung-Hui's deadly rampage at Virginia Tech:
Many people -- and especially many adolescent and young adult men -- are troubled. Many are severely depressed. Many express disturbing, violent fantasies. Fortunately, only a tiny fraction commit lethal acts against others. And unfortunately, those who do often do not stand out ahead of time.
This is what forensic psychologist Robert Fein found when he conducted a Secret Service study of all political assassins and would-be assassins in the United States over the past 60 years. Contrary to popular mythology, the assassins fit no singular "profile." They were neither monsters nor martyrs, Fein said:
The reality of American assassination is much more mundane, more banal, than assassinations depicted [in movies].
The myth of the deranged killer

Jared Loughner’s delusional ramblings, revealed to the world by intrepid Internet sleuths, are the only explanation some people need. But they are something of a red herring.

First, as advocates for the mentally ill are quick to point out, the link between psychosis and violence is far from settled. Most people with severe mental disorders do not become violent. Any increased risk is miniscule compared with the risk posed by use of alcohol or drugs, according to large-scale studies. As Vaughan Bell puts it in his lucid summary of this research:
Psychiatric diagnoses tell us next to nothing about someone's propensity or motive for violence…. It's likely that some of the people in your local bar are at greater risk of committing murder than your average person with mental illness.
But even when an assassin does harbor delusional beliefs, this is not sufficient explanation. Loughner's gender likely played a role, too, as men commit far more violence than women. Yet we would never think we had explained the Tucson rampage with the statement: "Loughner was a man."

In fact, the Secret Service study found that the assassins who were delusional -- about one-fourth of the total -- acted based on the same types of motivations as non-delusional assassins. As reporter Douglas Fox summarized:
Some hoped to achieve notoriety by killing a well-known person. Others wanted to end their pain by being killed by Secret Service. Still others hoped to avenge a perceived, idiosyncratic grievance unrelated to mainstream politics. Some hoped, unrealistically, to save the country or call attention to a cause. And some hoped to achieve a special relationship with the person they were killing.
Selecting one's lens: Micro or macro?

In our professional role, forensic psychologists use a micro lens, focusing on the individual level of analysis. But when commentators focus solely on individual-level factors, they divert the public from contextual factors that may be more amenable to prevention.

In other words, at the micro level there is no question that Loughner is a troubled young man. But at the macro level, his choice of targets certainly reflects the political tensions in the United States and especially in Arizona, which even the local sheriff described as a "Mecca for prejudice and bigotry."

Sarah Palin is able to evade responsibility for her violent rhetoric by strategically refocusing on the culturally entrenched myth of the dangerous schizophrenic, and calling Loughner "deranged" and "evil."

Ironically, it is the mentally unstable like Loughner who are most vulnerable to extremist rhetoric, and other memes floating around in our cultural ethos. As prominent forensic psychologist and law professor Charles Patrick Ewing noted:
These influential politicians and commentators who use violent rhetoric and images -- such as putting a member of Congress in the crosshairs, telling supporters that it is time to 'reload' and suggesting that voters unhappy with Congress resort to 'Second Amendment remedies' -- must realize that they have an incredibly wide audience. At least some members of that audience (both sane and insane) will view their inflammatory statements as an invitation to violence…. The blame for these killings does not lie with the perpetrator alone."
"Stochastic terrorism" is the term invoked by one professor of communications to describe this phenomenon, of "use of mass communications to stir up random lone wolves to carry out violent or terrorist acts that are statistically predictable but individually unpredictable."

What if Abdul had done it?

That the micro lens is a deliberate choice becomes clearer if we ask ourselves how media coverage might be different if a Muslim from the Middle East had shot U.S. Rep. Gabrielle Giffords. Would the focus still be on individual pathology? Or would it be on his political affiliations and the content of his rhetoric?

The din of rhetoric about mental illness drowns out the voices of those framing Loughner's attempted assassination as an act of political terrorism. People like Jesse Muhammed, Sahar Aziz, and Cenk Uygur, who asks incredulously:

Is this a joke? He shot a politician in the head. He called it an "assassination." What part of that was unclear? … [W]hy does the act have to be either psychotic or political? It's obviously both.… The conservative hate-mongers don't create psychos…. [But] they channel their fear, anger and paranoia…. They load them up with violent imagery, whether it's talk of cross-hairs or second amendment remedies or the tree of liberty being refreshed with blood. Then when they get a violent reaction they pretend to be surprised and outraged that anyone would suggest they were the least bit culpable. The reality is that it is a simple formula -- violent imagery in, violent results out.
In the final analysis, the causes of violence are multifaceted and difficult to disentangle. And it is impossible to predict which troubled, angry and alienated young man will engage in lethal violence. But one thing is certain: More laws are not the answer. They cast too wide a net, and distract from the search for deeper solutions.

    How competent are the competency evaluators?

    Largest real-world study finds modest agreement among independent alienists

    A bad forensic report by a bad evaluator sets bad events in motion.

    True story: A judge ordered a robbery suspect to undergo evaluation. A drive-by psychologist opined that the defendant was incompetent to stand trial due to schizophrenia and attention deficit/hyperactivity disorder (ADHD). The judge rubber-stamped the evaluator's opinion. The defendant was shipped off to the dysfunctional state hospital system for competency restoration treatment. There, the psychologist's diagnoses were rubber-stamped. The unruly defendant was shot full of powerful antipsychotics, given a few months of bus therapy, and proclaimed competent. The defendant had never been psychotic in the first place. Years later, he remained just as mentally retarded as ever.

    "Penny-wise, pound-foolish" is the expression that comes to mind. The courts try to save money by appointing only one psychologist per case, and by paying a ludicrously small sum that encourages shoddy practices. But cleaning up the resultant messes is costly, inefficient, and fundamentally unfair.

    Competency evaluations are the bread and butter of forensic work. An estimated 60,000 defendants per year -- roughly 5% of the total -- are evaluated to see whether they understand their legal situations and can rationally assist their lawyers in their defense. But for all of the importance of accurate assessments, both to a smoothly running court system and to the rights of the mentally ill to a fair trial, surprisingly little is known about the real-world accuracy of forensic evaluators.

    In the case I just outlined, the judge viewed psychologists and psychiatrists as equal and interchangeable, all inherently reliable and trustworthy. At the other extreme, some believe forensic opinions are as random as a chimp with a typewriter.

    Hawaii: Exemplar or exception?

    Only one U.S. state squarely addresses the problem of reliability in competency evaluations. In the Aloha State, when a doubt is raised as to a defendant's competency, three separate evaluators must conduct independent evaluations. One evaluator is a state employee; the other two are independent. One must be a psychiatrist. By law, the three cannot talk with each other about the case.

    This makes Hawaii the perfect setting to examine the real-world reliability of competency evaluators. In a study just accepted for publication in Law and Human Behavior, three investigators took advantage of this opportunity to conduct the largest naturalistic study ever of evaluators' agreement about competency to stand trial.

    It should not be a surprise that Daniel Murrie and Marcus Boccaccini are two of the investigators. Not the types to run Psych 101 undergrads through artificial lab experiments, these two are committed to examining forensic practice in the courtroom trenches. I've blogged about their previous work exposing "partisan allegiance" effects in the real-world application of the Psychopathy Checklist (PCL-R). For the current innovative study, they teamed up with W. Neil Gowensmith of the Hawaii courts' forensic services unit.

    Examining 729 reports authored by 35 evaluators, they found that all three evaluators agreed in just under three out of four -- or 71 percent -- of initial competency referrals. Agreement was a bit lower -- 61 percent -- in cases where defendants were being reevaluated after undergoing competency restoration treatment.

    Consistent with the results of a hot-off-the-press meta-analysis of 50 years of competency research, evaluators believed that the broad majority of defendants referred for evaluation, about 73 percent, were competent to stand trial. This figure was somewhat lower for defendants being reevaluated after an initial finding of competency, with evaluators opining competence in about half of such restoration cases.

    Why do evaluators differ?

    As far as why agreement is not higher, the study raised more questions than it answered. The researchers sifted through the data looking for patterns, but none jumped out. Evaluators did not lean one way or the other by discipline (psychologist vs. psychiatrist) or by employer (state versus private practice). Defendant demographics were not explanatory. Nor were evaluator disagreements about diagnosis.

    It would be interesting to conduct qualitative analyses of the 216 cases in this study to see whether those in which evaluators differed were more complex and ambiguous than the others. I suspect that to be the case.

    Competency is nebulous. It exists along a continuum, so there is no precise cut point at which a defendant is automatically "competent" or "incompetent" to go forward with his legal case. Thus, evaluator agreement will never be perfect, nor -- necessarily -- should it be.

    How did the judges rule?

    One of the more intriguing aspects of the study was its exposition of how judges ruled after being presented with three reports. Not surprisingly, when evaluators were unanimous or split 2-1, the judges tended to go with the majority. But unlike the judge in the vignette I described earlier, many Hawaiian judges were independent thinkers who did not just rubber-stamp the evaluators' opinions.

    When they disagreed with the opinions of the court-appointed psychologists and psychiatrists, it was typically to find a defendant incompetent. In fact, in a few cases the judges found defendants to be incompetent even when all three evaluators believed a defendant was competent. In this way, they elevated defendants' due-process rights over prosecutorial efficiency. But maybe that's just Hawaii.

    Moving forward

    I found the results somewhat encouraging. When not subjected to partisan allegiance pressures, forensic practitioners agreed about three-fourths of the time about whether a defendant was competent to stand trial or not.

    Still, if these results are generalizable, it means evaluators will disagree in about two or three cases out of every ten. So in jurisdictions that appoint only a single evaluator, the researchers point out, many judges may be unwittingly rubber-stamping an idiosyncratic -- and even patently incorrect -- opinion:
    [T]o the extent that there is a factually correct answer to the question of whether or not a defendant is competent to stand trial, relying on one evaluator increases the likelihood that the court reaches an incorrect decision (by following an incorrect single opinion that would have been revealed as a minority opinion if other evaluations were available). In some instances, this may result in delaying a trial while a defendant is unnecessarily hospitalized. In other instances this may result in a defendant proceeding to trial when additional evaluator(s) would have opined the defendant was unable to participate meaningfully in that trial….

    The justice system needs to continue to wrestle with how to handle these competing demands -- efficient use of resources versus fair consideration of defendants' right to due process.
    Murrie and Boccaccini are on a roll. Let's hope they keep churning out this ground-breaking line of research, examining the real-world vagaries of forensic practice, and that others climb down from the ivory towers and jump on their bandwagon.

    As they note, "naturalistic studies of field reliability are an essential first step in gauging wide-scale quality across all manner of forensic practice and targeting areas for improvement."

    MLK to psychologists: We need creative maladjustment

    In honor of today's holiday, I am excerpting portions of a speech by Martin Luther King Jr. to psychologists, which remains prophetically relevant to our field today. I have made the entire speech, "The Role of the Behavioral Scientist in the Civil Rights Movement," available for download (HERE).

    ... For social scientists, the opportunity to serve in a life-giving purpose is a humanist challenge of rare distinction.... Social scientists, in the main, are fortunate to be able to extirpate evil, not to invent it....

    On crime and urban violence

    After some years of Negro-white unity and partial success, white America shifted gears and went into reverse. Negroes, alive with hope and enthusiasm, ran into sharply stiffened white resistance at all levels and bitter tensions broke out in sporadic episodes of violence. New lines of hostility were drawn and the era of good feeling disappeared....

    Science should have been employed more fully to warn us that the Negro, after 350 years of handicaps, mired in an intricate network of contemporary barriers, could not be ushered into equality by tentative and superficial changes.... Negroes could contain their rage when they found the means to force relatively radical changes in their environment. [But] without a more effective tactic for upsetting the status quo, the power structure could maintain its intransigence and hostility. Into the vacuum of inaction, violence and riots flowed and a new period opened....

    Urban riots ... are a distorted form of social protest. The looting which is their principal feature serves many functions. It enables the most enraged and deprived Negro to take hold of consumer goods with the ease the white man does by using his purse. Often the Negro does not even want what he takes; he wants the experience of taking. But most of all, alienated from society and knowing that this society cherishes property above people, he is shocking it by abusing property rights. There are thus elements of emotional catharsis in the violent act....

    The policymakers of the white society have caused the darkness; they create discrimination; they structured slums; and they perpetuate unemployment, ignorance and poverty. It is incontestable and deplorable that Negroes have committed crimes; but they are derivative crimes. They are born of the greater crimes of the white society. When we ask Negroes to abide by the law, let us also demand that the white man abide by law in the ghettos. Day-in and day-out he violates welfare laws to deprive the poor of their meager allotments; he flagrantly violates building codes and regulations; his police make a mockery of law; and he violates laws on equal employment and education and the provisions for civic services. The slums are the handiwork of a vicious system of the white society; Negroes live in them but do not make them any more than a prisoner makes a prison. Let us say boldly that if the violations of law by the white man in the slums over the years were calculated and compared with the law-breaking of a few days of riots, the hardened criminal would be the white man....

    The unemployment of Negro youth ranges up to 40 percent in some slums. The riots are almost entirely youth events--the age range of participants is from 13 to 25. What hypocrisy it is to talk of saving the new generation--to make it the generation of hope--while consigning it to unemployment and provoking it to violent alternatives.

    When our nation was bankrupt in the '30s we created an agency to provide jobs to all at their existing level of skill. In our overwhelming affluence today what excuse is there for not setting up a national agency for full employment immediately?

    ... These are often difficult things to say but I have come to see more and more that it is necessary to utter the truth in order to deal with the great problems that we face in our society....

    On taking a stand

    There are those who tell me that I should stick with civil rights, and stay in my place. I can only respond that I have fought too hard and long to end segregated public accommodations to segregate my own moral concerns. It is my deep conviction that justice is indivisible, that injustice anywhere is a threat to justice everywhere....

    On some positions cowardice asks the question, 'Is it safe?!' Expediency asks the question, 'Is it politic?' Vanity asks the question, 'Is it popular?' But conscience must ask the question, 'Is it right?!' And there comes a time when one must take a stand that is neither safe, nor politic, nor popular. But one must take it because it is right....

    On the role of the social scientist

    Negroes have been oppressed for centuries not merely by bonds of economic and political servitude. The worst aspect of their oppression was their inability to question and defy the fundamental precepts of the larger society. Negroes have been loathe in the past to hurl any fundamental challenges because they were coerced and conditioned into thinking within the context of the dominant white ideology.... For the first time in their history, Negroes have become aware of the deeper causes for the crudity and cruelty that governed white society's responses to their needs. They discovered that their plight was not a consequence of superficial prejudice but was systemic.

    The slashing blows of backlash and frontlash have hurt the Negro, but they have also awakened him and revealed the nature of the oppressor. To lose illusions is to gain truth. Negroes have grown wiser and more mature and they are hearing more clearly those who are raising fundamental questions about our society whether the critics be Negro or white. When this process of awareness and independence crystallizes, every rebuke, every evasion, become hammer blows on the wedge that splits the Negro from the larger society.

    Social science is needed to explain where this development is going to take us. Are we moving away, not from integration, but from the society which made it a problem in the first place? How deep and at what rate of speed is this process occurring? These are some vital questions to be answered if we are to have a clear sense of our direction....

    The problem is deep. It is gigantic in extent, and chaotic in detail. And I do not believe that it will be solved until there is a kind of cosmic discontent enlarging in the bosoms of people of good will all over this nation....

    On creative maladjustment

    There are certain technical words in every academic discipline which soon become stereotypes and even clichés. Every academic discipline has its technical nomenclature. You who are in the field of psychology have given us a great word. It is the word maladjusted. This word is probably used more than any other word in psychology. It is a good word; certainly it is good that in dealing with what the word implies you are declaring that destructive maladjustment should be destroyed. You are saying that all must seek the well-adjusted life in order to avoid neurotic and schizophrenic personalities.

    But on the other hand, I am sure that we will recognize that there are some things in our society, some things in our world, to which we should never be adjusted. There are some things concerning which we must always be maladjusted if we are to be people of good will. We must never adjust ourselves to racial discrimination and racial segregation. We must never adjust ourselves to religious bigotry. We must never adjust ourselves to economic conditions that take necessities from the many to give luxuries to the few. We must never adjust ourselves to the madness of militarism, and the self-defeating effects of physical violence.

    In a day when Sputniks, Explorers and Geminies are dashing through outer space, when guided ballistic missiles are carving highways of death through the stratosphere, no nation can finally win a war. It is no longer a choice between violence and nonviolence, it is either nonviolence or nonexistence. As President Kennedy declared, 'Mankind must put an end to war, or war will put an end to mankind.' And so the alternative to disarmament, the alternative to a suspension in the development and use of nuclear weapons, the alternative to strengthening the United Nations and eventually disarming the whole world, may well be a civilization plunged into the abyss of annihilation. Our earthly habitat will be transformed into an inferno that even Dante could not envision.

    Thus, it may well be that our world is in dire need of a new organization, The International Association for the Advancement of Creative Maladjustment. Men and women should be as maladjusted as the prophet Amos, who in the midst of the injustices of his day, could cry out in words that echo across the centuries, 'Let justice roll down like waters and righteousness like a mighty stream'; or as maladjusted as Abraham Lincoln, who in the midst of his vacillations finally came to see that this nation could not survive half slave and half free; or as maladjusted as Thomas Jefferson, who in the midst of an age amazingly adjusted to slavery, could scratch across the pages of history, words lifted to cosmic proportions, 'We hold these truths to be self evident, that all men are created equal. That they are endowed by their creator with certain inalienable rights. And that among these are life, liberty, and the pursuit of happiness.' And through such creative maladjustment, we may be able to emerge from the bleak and desolate midnight of man’s inhumanity to man, into the bright and glittering daybreak of freedom and justice.

    I have not lost hope. I must confess that these have been very difficult days for me personally. And these have been difficult days for every civil rights leader, for every lover of justice and peace.

    King was assassinated seven months after giving this speech at the American Psychological Association's 1967 convention.

    fMRI controversies: Special journal section

    A special section of the Association for Psychological Science's journal, Perspectives on Psychological Science, is dedicated to controversies surrounding functional Magnetic Resonance Imaging, or fMRI, technology. The articles* are:
    • Neuroimaging: Voodoo, New Phrenology, or Scientific Breakthrough? Introduction to Special Section on fMRI by Ed Diener -- In response to the widespread interest following the publication of Vul et al (2009), Perspectives Editor Ed Diener invited researchers to contribute articles for a special section on fMRI, discussing the promises and issues facing neuroimaging.
    • Mistreating Psychology in the Decades of the Brain by Gregory A. Miller -- Scientists tend to consider psychology-biology relationships in two distinct ways: by assuming that psychological phenomena can be fully explained in terms of biological events and by treating them as if they exist in separate realms. These approaches hold up scientific progress and have important implications for clinical practice and policy decisions (e.g., allocating research funds).
    • Brain Imaging, Cognitive Processes, and Brain Networks by Brian D. Gonsalves and Neal J. Cohen -- The growth of neuroimaging research has led to reflection on what those techniques can actually tell us about cognitive processes. When used in combination with other cognitive neuroscience methods, neuroimaging has promise for making important advancements. For example, neuroimaging studies on memory have raised questions not only about the regions involved with memory but also about component cognitive processes (e.g., the role of different attention subsystems in memory retrieval), and this has resulted in more theorizing about the interactions of memory and attention.
    • Mapping Mental Function to Brain Structure: How Can Cognitive Neuroimaging Succeed? by Russell A. Poldrack -- To understand the anatomy of mental functions, researchers may to need to move away from commonly used brain mapping strategies and begin searching for selective associations. This will require more emphasis on the structure of cognitive processes, which may be achieved through development of formal ontologies (e.g., the Cognitive Atlas) that will describe the “parts” and processes of the mind. Using these ontologies in combination with large-scale data mining approaches may more directly relate mental processes and brain function.
    • The Appeal of the Brain in the Popular Press by Diane M. Beck -- Why do people like the brain so much? Brain-related articles in the press, especially ones about fMRI research, tend to be very popular with the general public, but many of these articles may result in misinterpretations of the science. Part of the popularity may be attributed to their deceptively simple message: Perform an action and a certain area lights up. In addition, people are more confident in “biological” images than in the behavioral phenomena on which the images are based. In order to maintain trust with the public, scientists have a responsibility to provide the press with descriptions of research and interpretations of results research that are clear, relevant, and scientifically accurate.
    • Frontiers in Human Neuroscience: The Golden Triangle and Beyond by Jean Decety and John Cacioppo -- The development of neuroimaging has created an opportunity to address old questions about brain function and behavior in new ways and also to uncover new questions. The knowledge that emerges from neuroimaging studies is more likely to be beneficial when combined with techniques and analyses that break down complex constructs into structures and processes, measures that gauge neural events across different times, and animal studies.
    • Bridging Psychological and Biological Science: The Good, Bad, and Ugly by Arthur P. Shimamura -- The advent of functional neuroimaging has brought both praise and criticism to the field of psychological science. Although most studies relying on fMRI are correlative, they do offer some clues about the biology underlying psychological processes. However, it is not sufficient to show which area of the brain is involved in a particular cognitive process; rather theories need to address “how?” questions (e.g., How does the hippocampus contribute to remembering?) in order to best bridge psychological and biological science.
