In an experiment seemingly ripped from Law and Order or CSI, UK Psychologists Rob Jenkins and Christine Kerr demonstrated that it is possible to identify the faces of unseen bystanders in a photograph via the reflections in the eyes of the photographed individuals. Jenkins and Kerr took portrait pictures of individuals while other participants stood out of the photograph but in the line of site of the photographed subject. The researchers then used photo-editing techniques to extract faces in the reflections of the eyes of those photographed. Using these extracted facial images, they conducted two tests of identification: a face-matching task and a spontaneous recognition task. In both tasks participants were able to identify those in the picture at rate better than chance. Given the well-documented human ability to recognize faces, even in poor quality images, the result is not especially surprising. What is striking, however, is the original source of the image, and the fact that despite being 30,000 times smaller than the subject’s face in the original photograph, the extracted faces were still identifiable–which is a testament to both modern photographic technology and the human ability to recognize faces. Generalizing their work, Jenkins and Kerr highlight the applicability of this technique to aid in criminal investigations, where film and camera are recovered as evidence.

“Misinformation, disinformation, and violent conflict: From Iraq and the “War on Terror” to future threats to peace”
“Truth is the first casualty of war,” stated Aeschylus circa 500 BC*. Those words ring just as true 2500 years later. In a special issue of American Psychologist, Lewandosky et al. examined the ways misinformation in the digital age can contribute to war and conflict and reviewed the psychological processes that contribute to the support and perpetuation of misinformation. Lewandosky et al. employ two case studies in their review: a retrospective examination of the effect of misinformation during the 2003 Iraq War and the “War on Terror,” and a prospective look at the potential conflicts that could arise as a result of climate change–partly due to the misinformation that surrounds the subject.
In both cases, an individual’s worldview is a key determinant of the way he or she will process information, with research demonstrating that conservatives and liberals are likely to believe in the narratives that align with their worldview. With regard to the Iraq War, called for by a Republican president, an aggregate of poll data showed that 61% of Republicans and 18% of Democrats believed WMDs existed in Iraq before the US invasion. In the case of climate change, Lewandosky point out that although 97% of climate scientists agree that the globe is warming and human activity is a cause, misinformation abounds. One study found that 20% of those asked in a US survey felt climate change was a hoax.
The authors point out that people are predisposed “to believe what they hear or read because speakers are assumed to be truthful,” and once belief in a certain argument takes hold it can be hard to correct, even if people are presented with correct information. This is best illustrated by the worldview backfire effect, which occurs when people who believe in misinformation are presented with the actual facts, yet subsequently believe more strongly in the misinformation. The authors hope that an understanding of the psychological processes surrounding the belief in and perpetuation of misinformation will help refute incorrect information and thereby help avoid conflict. Throughout their discussion, they identified several ways adherence to one’s worldview can be lessened and belief in misinformation can be corrected: by reframing the narrative, inducing skepticism of the message’s source, correction of misinformation by the media, and through self-affirmation.

“Practice makes perfect,” as the saying goes, but not all practice is created equal. Researchers point to deliberate practice as a key to learning and high levels of achievement. Deliberate practice is categorized as an activity designed to improve specific aspects of performance, and is often rated as more challenging, more effortful, and less enjoyable than other activities. In an online-first publication in the Journal of Experimental Psychology: Learning, Memory, and Cognition, Coughlan et al. investigated the ways in which expert and intermediate Gaelic football players differed in aspects of deliberate practice, and the extent to which these differences related to improvement in a kicking task. The expert and intermediate footballers were evaluated based on their ability to perform two types of kicks in a pre-test, acquisition phase (4 practice sessions), post-test, and retention test.
The results revealed that expert players chose to focus more on their weaker of the two kicks, while intermediate players tended to focus on their stronger kick. Both groups showed improvement, from the pre to post-test, on the respective kicks they practiced most, however only experts maintained the improvement in the retention test. This, the authors suggest, may indicate more permanent learning for the experts, and, consistent with predictions of deliberate practice theory, experts were also more likely to find practice more physically and mentally effortful, and less enjoyable. The researchers also found that experts were also more efficient during practice and planned their kicks more often. Overall, the study represents a new way to study the effects of practice in real time, rather than through retrospective reports, and supports the idea that experts engage in practice that is qualitatively different than those with lesser skill.

Do the negative psychological consequences of a pay cut differ in magnitude than the positive psychological consequences of a pay raise? Researchers haves shown that people tend to be loss averse. That is, people anticipate losses, in money for example, will have greater negative effects than an equally sized gain will have positive effects. While a significant body of research demonstrates the effect anticipated losses or gains have on anticipated well-being, a recent study, published in Psychological Science, Boyce et. al set out to examine the actual effects of pay cuts and pay raises on actual psychological well-being. Boyce et al. utilized two large, longitudinal, national datasets from German and British Households to compare changes in income to changes in subjective well-being. The researchers found that actual raises and cuts in income have similar psychological effects as anticipated raises and cuts, and thereby provide the first evidence that the concept of loss aversion applies to both anticipated and actual experience. Thus, a lower income, if stable, may be better for psychological well-being than a higher, but less stable one. Such findings have significant sociopolitical implications, as small reductions in national income levels, for example, may negate the increases in subjective well-being that a nation’s inhabitants receive from overall income growth.

In a cross-cultural study of emotion, published in the December issue of Emotion, Park et al. explored the relationship between anger and social status in American and Japanese adults. Park et al. point out that while research has linked low status individuals to higher levels of anger, the work to date has been conducted primarily on Western populations. In the West, anger is primarily used to vent frustration–a precursor to anger thought to be the result of limited opportunity to pursue individual goals. In Japan, however, due to the interdependent nature of the culture, anger is not as readily expressed. Japanese of high status, however, may be more willing to display anger as a way to exert authority and dominance over others.
In the present work, Park et al employed large representative surveys in both the United States and Japan to study the relationship between anger, subjective and objective social status, and frustration. Consistent with previous research Park et al. found that Americans who reported lower subjective social status were more likely to report being angry, with the link between status and anger mediated by level of frustration. Conversely, objectively higher status Japanese were more likely to report anger, with the link between status and anger mediated by decision-making authority. These results suggest culture moderates the link between an individual’s expression of anger and his or her social status. More broadly, this study highlights the role culture plays in emotional expression.
