MedicalResearch.com Interview with: “Rugby” by Jim Ceballos is licensed under CC BY 2.0Dr. Yusuke Kuroda PhD Massey University New Zealand MedicalResearch.com: What is the background for this study? What are the main findings? Response: Similar study, examining motivational personality among rugby players from four different countries (but all from predominantly Anglo-Saxon), was conducted in the late 1980s, and that study showed that elite rugby players, regardless of nationality, possessed serious minded and goal oriented personality. Number of studies examined athletes in different sports and showed similar results. Previously, I had a chance to examine Maori and Japanese people engaged in traditional dance from their own culture; and, the Maori people were predominantly playful and spontaneous oriented, while the Japanese people were predominantly serious minded and goal oriented. Dr Farah Palmer, one of co-authors, and I wanted to examine whether Maori All Blacks and Japanese National Team rugby players and see whether motivational personality of them were driven by being elite athletes or from cultural background. To play for the Maori All Blacks, players have to have a Maori background. The Japanese National Team, on the other hand, was consisted of Japanese and foreign born players. To examine the effect of culture, we also examined cultural identity among players. With the help from Associate Professor Makoto Nakazawa, we got to measure motivational personality and cultural identity from both teams, and results showed that the Maori All Blacks players were more playful minded spontaneous oriented, while the Japanese National Team players were serious minded and goal oriented. Cultural identity showed that the Japanese National Team players, even with foreign born players, showed a greater knowledge of the Japanese culture and higher comfort level in their own culture than the Maori All Blacks players (or their own culture). However, the Maori All Blacks players felt more positive and sustain the Maori culture. (more…)

MedicalResearch.com Interview with: Alex Maier, PhD Assistant Professor of Psychology Assistant Professor of Ophthalmology and Visual Science Vanderbilt University MedicalResearch.com: What is the background for this study? What are the main findings? Response: We were interested in finding out about how the brain shifts attention from one location to another. We knew that when we attend a certain location, brain activity increases in a specific way. This increase in activity is how we perform better when we use attention. What we knew less about is what happens when attention moves between locations. To our surprise, we found that there is a brief moment in between these attentional enhancements, while attention moves from one location to another, where the brain does the complete opposite and decreases its activity. Shifting attention thus has a brief negative effect on our brain’s ability to process information about the world around us. (more…)

MedicalResearch.com Interview with: Shari Liu Dept Psychology Harvard University Cambridge, MA 02138  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Every day, we look out into the social world and see more than pixels changing across our retinas, or bodies moving in space. We see people brimming with desires, governed by their beliefs about the world and concerned about the costs of their actions and the potential rewards those actions may bring. Reasoning about these mental variables, while observing only people’s overt behaviors, is at the heart of commonsense psychology. (more…)

MedicalResearch.com Interview with: “FACEBOOK(LET) Front” by FACEBOOK(LET) is licensed under CC BY 2.0Phillip Ozimek M.Sc. Department of Social Psychology Faculty of Psychology Ruhr-University Bochum UniversitätsstrBochum, Germany MedicalResearch.com: What is the background for this study? Response: We started reading the classic book by Erich Fromm „To have or to be“ out of personal interest. I was very much interested in studying social media, so we wondered how materialists would use facebook. After all Facebook seemed to be a perfect tool for people who love social comparisons. Furthermore, Facebook is for free – materialists love tools that do not cost money! (more…)

MedicalResearch.com Interview with: Dr. Miguel Farias, DPhil Reader in Cognitive and Biological Psychology Coventry University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the past 20 years, cognitive psychologists have suggested that believing in the supernatural is something that comes to us 'naturally' or intuitively. Previous studies have suggested people who hold strong religious beliefs are more intuitive and less analytical, and when they think more analytically their religious beliefs decrease. Our new research has challenged this. We used various experimental methods, including field research in the pilgrimage route to Santiago de Compostela and neural stimulation. , by academics from Coventry University's Centre for Advances in Behavioural Science and neuroscientists and philosophers at Oxford University, suggests that is not the case, and that people are not 'born believers'.

MedicalResearch.com Interview with: Angeline Lillard PhD Professor of Psychology University of Virginia Charlottesville, VA MedicalResearch.com: What is the background for this study? Response: Montessori education was developed in the first half of the last century, but has been subject to little formal research. Prior research on its outcomes was problematic in using poor control groups, very small samples, demographically limited samples, a single school or classroom, or poor quality Montessori, or data from just a single time point and limited measurements. This study addressed all these issues: it collected data 4 times over 3 years from 141 children, experimental children were in 11 classrooms at 2 high quality Montessori schools at which the control children were waitlisted and admission was done by a randomized lottery, family income ranged from $0-200K, groups were demographically equivalent at the start of the study, and many measures were taken.

MedicalResearch.com Interview with: Karen L. Bales PhD Professor of Psychology University of California Davis, CA 95616 MedicalResearch.com: What is the background for this study? Response:  Titi monkeys are a socially monogamous species in which adults form pair bonds.  In my laboratory we are studying the neurobiology of pair bonding, and understanding jealousy is important because it's one mechanism by which the pair bond is maintained.  In this study, male titi monkeys viewed their pair mate next to a stranger male, and we examined the neural, behavioral, and hormonal consequences.  (more…)

MedicalResearch.com Interview with: Tobias Gerstenberg, PhD MIT MedicalResearch.com: What is the background for this study? What are the main findings? Response: The question of how causation is best understood has been troubling philosophers for a long time. As psychologists, we are particularly interested in understanding how people make causal judgments. In our experiments, we showed participants video clips of colliding billiard balls. Participants were asked to say whether one ball (ball A) caused another (ball B) to go through a gate, or prevented it from going through. We used eye-tracking technology to record participants' eye-movements as they were watching the clips. The results showed that participants spontaneously engaged in counterfactual simulation when asked to make causal judgments. They not only looked at what actually happened, but also tried to anticipate where ball B would have gone if ball A hadn't been present. The more certain participants were that ball B would have missed the goal if ball A hadn't been there, the more they agreed that ball A caused ball B to go through the gate. In a control condition we asked participants about what actually happened. In this condition, participants were much less likely to simulate where ball B would have gone. Together, these findings demonstrate a very close link between counterfactual simulation and causal judgment. (more…)

MedicalResearch.com Interview with: Tamara Masters, PhD Marketing Marriott School of Management Brigham Young University MedicalResearch.com: What is the background for this study? What are the main findings? Response: As a marketing professor I have studied the disparity of what people are willing to sell items/products for and how much that differs from how much others are willing to pay. I do research in consumer decision making and find the neurophysiological aspects of consumers fascinating.  I read medical and neuroscience research for fun and see many ways individuals may be effected in the use of their limited resources.  We are all consumers – many make purchases of some type daily – even it if it is to play online games or where and how to get our next meal. The main findings relate to how a person is either attached to or feels an aversion to losing an object.  There has been debate as to which of these factors leads to a difference in buy and selling prices.  This research provides a new and unique look at how BOTH factors must be present for this disparity to emerge.  This research is unique because it uses combines the fields neuroscience, psychology and economics to explain something we all experience.

MedicalResearch.com Interview with: Dr. Thekla Morgenroth Preferred pronouns: They/them/their Research Fellow in Social and Organisational Psychology Psychology University of Exeter Washington Singer Laboratories, Exeter UK  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Risk-taking is often seen as an important trait that leads to economic success - for example when it comes to investing money - and career success. For example, we often hear that leaders need to be willing to take risks. Risk-taking is also strongly associated with masculinity, which leads to the idea that maybe gender differences in economic and career success can be explained by the fact that women are just too risk averse. When you look at the risk-taking literature, it appears that there is support for this idea with many studies showing that men do indeed take more risks than men. Our research questions these ideas. We show that current measures of risk-taking are biased. They focus only on stereotypical "masculine" risk taking behaviors such as betting your money on the outcome of a sporting event or going whitewater rafting, and ignore the many risks that women take, such as going horseback riding or donating a kidney to a family member. When this bias is addressed, gender differences in risk-taking disappear or even reverse. (more…)

MedicalResearch.com Interview with: Vanda Faria PhD Department of Psychology Uppsala, Sweden  MedicalResearch.com: What is the background for this study? What are the main findings? Response: It has been debated whether selective serotonin reuptake inhibitors (SSRIs), which are commonly prescribed for depression and anxiety, are more effective than placebo. Concerns have been raised that the beneficial effects of SSRIs, as measured in double-blind clinical trials, may be explained by expectancies (a crucial placebo mechanism) rather than the biochemical compound. But no study has tested experimentally the extent to which the SSRI treatment effect can be influenced by expectancies induced by verbal suggestions. We compared the efficacy of overt vs. covert administration of an SSRI (escitalopram) in patients with social anxiety disorder. Rather than comparing the SSRI with placebo, we compared it with itself while manipulating the patients’ expectations of improvement. This was achieved by informing one group correctly about the SSRI and its effectiveness (overt group) whereas the comparison (covert) group received incorrect information. By use of a cover story, the covert group was led to believe they were treated with a so called “active placebo”, an ineffective neurokinin-1 antagonist yielding similar side effects as the SSRI but lacking anxiety-reducing properties. But the treatment, dosage and duration was in fact identical in both groups. Results showed that overt outperformed covert SSRI treatment, as the number of treatment responders was more than three times higher on the main clinical outcome measure when correct information was given. Using neuroimaging (fMRI) we also noted differences between the overt and covert SSRI groups on objective brain activity measures. There were differences between the groups e.g. with regard to activation of the posterior cingulate cortex with treatment, and the functional coupling between this region and the amygdala which is a brain region crucially involved in fear and anxiety. The fMRI  results may reflect the interaction between cognition and emotion as the brain changes differently with treatment pending on the expectations of improvement. (more…)

MedicalResearch.com Interview with: Patti J. Fisher, Ph.D. Associate Professor in Consumer Studies AHRM Department Virginia Tech MedicalResearch.com: What is the background for this study? Response: Risk tolerance is one of the most important factors contributing to wealth accumulation and retirement. It is important to understand why women are less risk tolerant so that financial planners can better serve their needs because women, on average, live longer than men and often need more retirement savings.

MedicalResearch.com Interview with: Malin Bergström PhD Center for Health Equity Studies Karolinska Institutet   MedicalResearch.com: What is the background for this study? Response: The increase in children who move between their parent's homes after a divorce is one of the major changes in children's life circumstances during the last decade. Spending equal amounts of time in both parents' homes means that these children move fifty times a year. Child experts have claimed this to be stressful and potentially harmful to children's attachment relations to their mothers. Especially for children this young the practice of joint physical custody has been questioned. (more…)

MedicalResearch.com Interview with: Jiah Yoo Ph.D. Student in Social Psychology University of Wisconsin-Madison Madison, WI 53706  MedicalResearch.com: What is the background for this study? Response: A growing number of studies have shown that positive emotions predict better physical health. However, a caveat of these findings is that most studies have been conducted with Western samples. As cultural psychologists, we have learned that European American cultural contexts are particular in that positive emotions are highly valued and emphasized. For example, in East Asian cultures, it is a commonly shared view that positive emotions have some dark sides such as that they are fleeting, may attract unnecessary attention from others, and can be a distraction from focusing on important tasks. Given the cultural differences in emotions, we thought it would be important to test whether the established link between positive emotion and enhanced physical health are relevant to other cultural contexts, such as those in East Asia. We focused on blood lipids profiles, one of the major risk factors for heart diseases, as objective measures of health. Because of the global prevalence of coronary artery diseases, blood lipids are considered important indices of biological health in many Western and East Asian countries. In addition, blood lipids are largely influenced by lifestyles and behavioral factors so we further tested the role of various health behaviors (i.e., dietary habits, body mass index, smoking, alcohol consumption) in the lipids-emotion link in different cultures.

MedicalResearch.com Interview with: Gili Freedman, PhD Postdoctoral Researcher Dartmouth College MedicalResearch.com: What is the background for this study? What are the main findings? Response: Social rejection is a common, everyday interpersonal interaction, and most people have been on both ends: being rejected and doing the rejection. There has been a lot of research on how rejection impacts targets (the people being rejected), but we know less about the point of view of the rejector. In this set of studies, we wanted to understand how frequently rejectors include apologies in rejections and what effect apologies have on targets of rejection. Using both college and community samples, we found that approximately 40% of people spontaneously included an apology when trying to reject in a good way. However, rejections with apologies were associated with more hurt feelings and higher levels of aggression than rejections without apologies. In response to viewing rejections with apologies, participants felt obligated to express forgiveness but did not actually feel forgiveness. Taken together, our results indicate that apologies may not be helpful in softening the blow of a social rejection. (more…)

MedicalResearch.com Interview with: Dan Romer PhD Research director, Annenberg Public Policy Center Director of its Adolescent Communication Institute University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: In recent years, findings from research in developmental neuroscience indicate that the myelination of the prefrontal cortex (PFC) extends into the third decade of life, proceeding more slowly than in other brain regions. Because subcortical and sensory brain regions appear to mature earlier, this and other findings have been taken as evidence that adolescents may have less ability to control their behavior than children do. These findings spawned theories of “imbalanced” adolescent brain development that were proposed to explain heightened vulnerability to risky behavior and adverse health outcomes during adolescence. Although there is little doubt that as adolescents enter adulthood, they are at risk for many health outcomes that can accompany the initiation of such behaviors as driving, having sex, using drugs, and playing sports. But most adolescents make it through this period of development without serious health consequences. Thus, the argument that a brain deficit is responsible for such adverse health outcomes seemed to overgeneralize effects that only occur for a minority of adolescents. Furthermore, when my colleagues and I examined the evidence in support of imbalance theories, we found it unconvincing. Indeed, it seemed that findings from neuroscience were interpreted through the lens of stereotypes about adolescents that conflate exploration with impulsivity. That is, many of the risky behaviors that attract adolescents are novel activities that reflect lack of experience rather than lack of control over behavior.  (more…)

MedicalResearch.com Interview with: Allison Mueller, A.B.D. Ph.D. Program Department of Psychology University of Illinois at Chicago  MedicalResearch.com: What is the background for this study? What are the main findings? Response: In our study, we explored how people react to public figures who bend the truth. We predicted that people’s own moral conviction for a political issue—their strong and absolute belief that this position is right or wrong, moral or immoral—would cloud their judgments of public figures who lie for that cause. We reasoned that when a strong moral conviction is at stake, the transgressiveness of specific kinds of advocacy for the cause may be trivialized. To test this idea, we first assessed people’s views on a political issue—in this case, whether they supported or opposed federal funding of Planned Parenthood, and the extent to which they viewed the issue as a moral imperative. They were then presented with a political monologue supporting Planned Parenthood that they believed was previously aired over public radio. After reading the monologue, they were randomly assigned to learn that the monologue was deemed true (or false) by several fact-checking organizations. We measured their reactions to hearing this news, including the extent to which they believed the speaker was justified in delivering the monologue and their judgments of the speaker’s moral character. We found that people’s perceptions of the speaker’s transgressive advocacy were uniquely shaped by their own moral conviction for the cause. Although honesty was positively valued by all respondents, transgressive advocacy that served a shared moral (vs. nonmoral) end was more accepted, and advocacy in the service of a nonpreferred end was more condemned, regardless of its truth value.  (more…)

MedicalResearch.com Interview with: Johanna MH Nijsten, Msc Clinical Neuropsychologist Archipel Landrijt, Knowledge Center for Specialized Care Eindhoven, the Netherlands Department of Primary and Community Care, Radboudumc Alzheimer Center Radboud University Medical Center Nijmegen, the Netherlands  MedicalResearch.com: What is the background for this study? Response: Apathy is common in nursing home (NH) patients with dementia and is repeatedly found to be the most prevalent neuropsychiatric symptom. Apathy is defined by diminished or lack of motivational, goal-directed behavior, and a lack of cognition and emotional affect. Apathy leads to reduced interest and participation in the main activities of daily living, diminished initiative, early withdrawal from initiated activities, indifference, and flattening of affect. Over the last two decades, more scientific knowledge has become available about specific fronto-subcortical systems in the brain that may be highly involved in apathy. Disruptions in these systems are found in patients with frontal lobe damage resulting from, for instance, (early-onset) dementia, traumatic brain injury, stroke, or multiple sclerosis. Fronto-subcortical circuits also play an important role in neurological disorders involving the basal ganglia such as Parkinson’s disease and Huntington’s disease. The neurodegenerative diseases and acquired brain injuries mentioned here are highly prevalent in patients receiving long-term NH care and the widespread clinical manifestation of apathy in NH-patients is thought to be related. Since apathy is very common in nursing home-patients and may lead to a poor prognosis, clear insight into its risk for mortality is needed and NH-staff need to understand this risk. (more…)

MedicalResearch.com Interview with: Mirkka Danielsbacka PhD, D.Soc.Sci Senior researcher University of Turku MedicalResearch.com: What is the background for this study? What are the main findings? Response: Relations between family generations are widely studied in disciplines such as family sociology and demography. However, relations between in-laws are often neglected in family studies of contemporary societies. Especially conflicts have been surprisingly little investigated. We were especially interested in how parenthood is associated with relations to in-laws in a contemporary Western society. Using nationally representative survey data from Finland with over 1,200 respondents, we studied conflicts that spouses reported having with their own parents and their in-laws. Overall, Finns more often reported having had any conflict with their own parents than with their in-laws. Compared to childless couples, couples with children were as likely to report conflicts with their own parents. However, couples with children were more likely to report conflicts with their parents-in-law. Our results took into account how frequently family members were in contact with each other and how emotionally close they felt, as well as other sociodemographic factors. (more…)

MedicalResearch.com Interview with: Mag. Nicole Mirnig  Research Fellow Center for Human-Computer Interaction University of Salzburg Salzburg, Austria  MedicalResearch.com: What is the background for this study? What are the main findings? Response: From our previous research on social robots, we know that humans show observable reactions when a robot makes an error. These findings result from a video analysis we performed over a large data corpus from different human-robot interaction studies. With the study at hand, we wanted to replicate this effect in the lab in order to explore into more detail how humans react and what they think about a robot that makes a mistake. Our main findings made us quite excited. First of all, we could show that humans respond to faulty robot behavior with social signals. Second, we found that the error-prone robot was perceived as significantly more likeable than the flawless robot. One possible explanation for this finding would be the following. Research has shown that people form their opinions and expectations about robots to a substantial proportion on what they learn from the media. Those media entail movies in which robots are often portrayed as perfectly functioning entities (good or evil). Upon interacting with a social robot themselves, people adjust their opinions and expectations based on their interaction experience. We assume that interacting with a robot that makes mistakes, makes us feel closer and less inferior to technology. (more…)

MedicalResearch.com Interview with: Jared Friedman Doctoral Student, Organizational Behavior Research Assistant II, Brain Mind and Consciousness Lab Case Western Reserve University MedicalResearch.com: What is the background for this study? What are the main findings? Response: These studies were motivated by our prior work in neuroscience and psychology.  Neuroscience research from our lab has shown that brain areas associated with empathy seem to share a ‘see-saw’ relationship with brain areas associated with analytic reasoning.  As activity in one set of brain areas goes up, activity in the other set of brain areas tends to go down.  This suggests there is a sort of neural antagonism between warm, empathic sorts of thinking on the one hand, and cold, analytic sorts of thinking on the other. In prior psychological work, we tested the hypothesis that these two different sorts of thinking might share opposing relationships to religious belief.  Over a series of 8 studies, we showed that although religious belief is negatively related to analytic reasoning skills (which many other labs had shown), it shares a much stronger positive relationship to measures of empathy and moral concern.  This suggests that religious belief, measured on a continuum, might emerge from the tension between empathic and analytic forms of thinking. The current studies expanded on this prior work by examining how dogmatism – strongly holding onto one’s beliefs, even in the face of contradictory evidence – relates to measures of moral concern and analytic reasoning among individuals identifying as religious and non-religious.  The measure of dogmatism we used is neutral with respect to any particular belief system, which means that it measures dogmatism in general (rather than dogmatism towards, for instance, religious beliefs).  We found that analytic reasoning negatively relates to dogmatic tendencies in both groups.  However, the interesting part is that higher levels of dogmatism among the religious were related to higher levels of moral concern, whereas higher levels of dogmatism among the nonreligious relate to lower levels moral concern.  This is very intriguing because it suggests that religious and nonreligious individuals rely differently on these two types of cognition when forming beliefs about the world, in general.  We also found that perspective taking, which is an emotionally detached form of understanding other people’s minds, had a particularly strong negative relationship among the nonreligious.

MedicalResearch.com Interview with: Omri Gillath PhD Department of Psychology University of Kansas Angela Bahns, PhD Wellesley College MedicalResearch.com: What is the background for this study? What are the main findings? Response: We tracked the eye movements of 105 heterosexual participants while they viewed photos of strangers and answered questions about their interest in either becoming friends with or dating the person. We found that in looking at others, people scan the body differently depending on whether a person is judged as a potential friend or a potential romantic partner. Heterosexual men and women looked at the head or chest of an opposite-sex person longer and more often when evaluating dating potential compared to friendship potential. In contrast, both men and women looked at the legs or feet more for friendship judgments than for dating judgments (although overall legs and feet were looked at less than other body regions).

MedicalResearch.com Interview with: Jason Han, MD Resident, Cardiothoracic Surgery Hospital at the University of Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: The inspiration for this study comes from my personal experience as a medical student on clinical rotations. Despite having been a victim of a medical error while growing up myself, I found it extraordinarily difficult to admit to even some of my smallest errors to my patients and team. Perplexed by the psychological barriers that impeded error disclosure, I began to discuss this subject with my advisory Dean and mentor, Dr. Neha Vapiwala. We wanted to analyze the topic more robustly through an academic lens and researched cognitive biases that must be overcome in order to facilitate effective disclosure of error, and began to think about potential ways to implement these strategies into the medical school curriculum with the help of the director of the Standardized Patient program at the Perelman School of Medicine, Denise LaMarra. We ultimately contend that any educational strategy that aims to truly address and improve error disclosure must target the cognitive roots of this paradigm. And at this point in time, simulation-based learning seems to be the most direct way to do so, but also remain hopeful that emerging technologies such as virtual and augmented reality may offer ways for students as well as staff to rehearse difficult patient encounters and improve.

MedicalResearch.com Interview with: Justin M. Kim, Ph.D Dartmouth College Advisor: Paul J. Whalen MedicalResearch.com: What is the background for this study? What are the main findings? Response: Anxiety (and its co-conspirator ‘worry’) is an active, energy consuming process. You haven’t given up - you are still fighting back, trying to anticipate what might happen tomorrow. The problem of course is that there are an infinite number of ‘what if…’ scenarios you can come up with. For some individuals, the uncertainty of what ‘might happen’ tomorrow, is actually worse than the negative event itself actually happening. These individuals are intolerant of uncertainty. We were interested in how uncertainty and ambiguity of potential future threat contribute to the generation of anxiety and how they might be represented in our brain. In the psychology literature, how we deal with an uncertain future can be quantified as intolerance of uncertainty (IU). As is the case with any other personality characteristic, we all have varying degrees of IU. For example, individuals high in IU display difficulty accepting the possibility of potential negative events in the future. Importantly, psychiatric disorders such as generalized anxiety disorder (GAD) or obsessive-compulsive disorder (OCD), whose symptoms are marked with worrying/obsessing, are commonly associated elevated IU. We noticed that while much of the neuroimaging research on IU has been primarily focused on brain function, brain structural correlates of IU have received little attention so far. As such, we believed that it was an important endeavor to assess the relationship between IU and the structural properties of the brain, which can be done through the use of magnetic resonance imaging (MRI) techniques.

MedicalResearch.com Interview with: Carlota Batres PhD Postdoctoral fellow at Gettysburg College MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for this study is that previous research has found that individuals from rural areas prefer heavier women than individuals from urban areas. Several explanations have been proposed to explain these preference differences: media exposure, differing optimal weights for different environments, and urbanization. In this study, we investigated familiarity as a possible explanation by examining participants’ face preferences while also examining the facial characteristics of the actual participants. The main finding of this study is that familiarity appears to be contributing to our facial preferences. (more…)

MedicalResearch.com Interview with: Indrajeet Patil PhD former PhD student at SISSA, Trieste and currently a postdoctoral researcher at Harvard University MedicalResearch.com: What is the background for this study? Response: Human societies are built on mutually beneficial cooperation, which relies on our prosocial and altruistic impulses to help each other out. Psychologists have been trying to understand the psychological basis of altruistic behavior for a while now, but studying costly altruism - a kind of helping behavior in which the altruist pays a heavy price to help others - has been difficult to study in lab settings given the ethical problems associated with creating any paradigm where participants stand to get hurt. Thus, the question is how do you study the motivation behind acts that involve a very high risk of physical injury to the self while helping others? Such situations are common in emergency contexts where people can be faced with the choice of either saving their own life or risking it to save someone else's life. (more…)

MedicalResearch.com Interview with: Brian Chin, B.S. PhD Student Doctoral Student Department of Psychology Carnegie Mellon University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Numerous studies demonstrate that married people tend to be healthier than those who are single, divorced, or widowed. However, less clear are the psychological and biological mechanisms through which this occurs. To this end, recent research has focused on how the unmarried may experience either greater amounts of stress or different types of stressful situations that put them at increased risk for morbidity and mortality. Models linking stress and disease often implicate the HPA axis as one pathway through which these stressful experiences can affect health. One way to index HPA axis activity is by measuring cortisol, a hormone that plays a regulatory role for many immunological and metabolic processes in the body. The primary aim of our study was to examine whether cortisol could be one biological mechanism through which marital status impacts health. Over three non-consecutive days, 572 healthy adult participants between 21-55 years old provided multiple saliva samples that were used to measure cortisol. Relative to their never married or previously married counterparts, married people had both lower cortisol outputs and steeper daily declines – both of which have been shown to be associated with better health outcomes.

MedicalResearch.com Interview with: Lazaros Gonidis PhD candidate Postgraduate Researcher University of Kent MedicalResearch.com: In general, why do we tend to underestimate time when we are distracted versus when we are doing something boring? Is the adage that “time flies when you’re having fun” true? Response:  In order to be accurate at time “keeping” we need to attend to it. Anything that distracts us makes us less accurate, and to be more specific, it makes us underestimate the duration of events. In simple terms when we experience an event that last 10 minutes a distraction could make it feel like 5 minutes. On the other hand when we are bored, let’s say during a non-interesting event, we tend to focus more on time keeping looking forward for the event to finish. In this case we would overestimate the event and 10 minutes could feel like 15 minutes. (more…)
