Moral decisions can be influenced by eye tracking
2015-03-18
(Press-News.org) Our opinions are affected by what our eyes are focusing on in the same instant we make moral decisions. Researchers at Lund University and other institutions have managed to influence people's responses to questions such as "is murder defensible?" by tracking their eye movements. When the participants had looked at a randomly pre-selected response long enough, they were asked for an immediate answer. Fifty-eight per cent chose that answer as their moral position.
The study shows that our moral decisions can be influenced by what we are looking at when we make the decision. Using a new experimental method, the researchers tracked participants' eye movements and demanded an answer when their eye rested on a randomly pre-selected answer.
The researchers, from the Division of Cognitive Science at Lund University, University College London (UCL) and the University of California, Merced, studied in real time how people deliberate with themselves in difficult moral dilemmas. The participants had no idea that the researchers were carefully monitoring how their gaze moved in order to demand an answer at the right moment. The results showed that the responses were systematically influenced by what the eye saw at the moment an answer was demanded.
"In this study we have seen that timing has a strong influence on the moral choices we make. The processes that lead to a moral decision are reflected in our gaze. However, what our eyes rest on when a decision is taken also affects our choice", explained Philip Pärnamets, cognitive scientist at Lund University and one of the authors of the study.
The study is the first to demonstrate a connection between gaze and moral choices, but it is based on previous studies which have shown that for simpler choices, such as choosing between two dishes on a menu, our eye movements say what we will eat for dinner before we have really decided.
"What is new is that we have demonstrated that if eye movements are tracked moment by moment, it is possible to track the person's decision-making process and steer it in a pre-determined direction", said Petter Johansson, a reader in cognitive science at Lund University.
The thought process needed to reach a moral position is thus interlinked with the process of viewing the world.
"Today, all sorts of sensors are built into mobile phones, and they can even track your eye movements", said Daniel Richardson, director of the Eye Think Lab at UCL. "By documenting small changes in our behaviour, our mobiles could help us reach a decision in a way that has not been possible before."

LUT has been developing materials and technology suitable for Arctic conditions. Principles for safe and ecological design and manufacturing of structures and devices used for energy production in the Arctic have been defined in the Arctic Materials Technologies Development project.
The LUT research focuses on the properties of new high-strength steel grades suitable for Artic construction and the welding methods they require. As a result, the productivity of welding has been significantly improved through reducing the groove angle essential to welding from 45 degrees ...

Brazilian researchers described five new species of ascidians, commonly known as sea squirts, ascidians are marine invertebrates that generally form permanently submerged colonies.
When the larval stage of the animals is completed, they attach themselves to rocks, shells and shipwrecks, losing the ability to swim or move. Their best defense against predators is the production of chemical substances.
What attracts researchers, besides the opportunity to enhance taxonomic knowledge of the group, are the potential uses of these natural compounds, which can contribute to ...

Philadelphia, PA, March 17, 2015 - Agricultural greenhouse gases (GHG) make up 8.1% of total U.S. GHG emissions. The dairy cattle farming industry is being challenged to reduce greenhouse gas emissions while maintaining or increasing profitability. In a study published in the Journal of Dairy Science®, researchers report that farms with lower carbon footprints and higher-producing cows are more profitable, a win-win situation for everyone, including the cows.
Investigators Di Liang, PhD candidate, and Victor E. Cabrera, PhD, from the Department of Dairy Science, University ...

A new study has found some scientists are unknowingly tweaking experiments and analysis methods to increase their chances of getting results that are easily published.
The study conducted by scientists at The Australian National University (ANU) is the most comprehensive investigation into a type of publication bias called p-hacking.
P-hacking happens when researchers either consciously or unconsciously analyse their data multiple times or in multiple ways until they get a desired result. If p-hacking is common, the exaggerated results could lead to misleading conclusions, ...

DENVER - The German Lung Cancer Screening Intervention Trial (LUSI) shows that the early repeat scan rate for suspicious findings decreased by more than 80% with the second and subsequent low-dose computed tomography (LDCT) screens, but emphasizes the need to have an organized screening program with the baseline scan available for comparison.
In the United States the National Lung Cancer Screening Trial (NLST) showed that annual lung cancer screening of high-risk individuals with LDCT reduces lung cancer mortality by 20% and overall mortality by 7%. There are now multiple ...

A new study, published today in the journal Scientific Reports, has identified a rural community in Brazil that still follows the earlier sleep and wake times similar to pre-industrial times.
The team of researchers from the University of Surrey and the University of São Paulo studied the population of Baependi, a small rural town in south-eastern Brazil, whose sleep/wake cycle is much more aligned with that of our ancestors.

A new technique invented at Caltech to produce graphene--a material made up of an atom-thick layer of carbon--at room temperature could help pave the way for commercially feasible graphene-based solar cells and light-emitting diodes, large-panel displays, and flexible electronics.
"With this new technique, we can grow large sheets of electronic-grade graphene in much less time and at much lower temperatures," says Caltech staff scientist David Boyd, who developed the method.
Boyd is the first author of a new study, published in the March 18 issue of the journal Nature ...

SPOKANE, Wash.--Washington State University researchers have found a mechanism by which omega-3 fatty acids inhibit the growth and spread of prostate cancer cells. The findings, which are at odds with a 2013 study asserting that omega-3s increase the risk of prostate cancer, point the way to more effective anti-cancer drugs.
Scientists have long known that omega 3s reduce inflammation and have anti-diabetic effects, and some recently discovered how this happens.
"But we're the first to show that they work this way in cancer," said Kathryn Meier, a professor of pharmacy ...

NEW YORK (March 17, 2015)--A new tuberculosis (TB) drug regimen designed to improve options for TB therapy eliminated more bacteria from sputum than standard therapy and did so at a faster rate, according to data from a phase 2b clinical trial published today in The Lancet. These results are published just as the global phase 3 clinical trial, designed to bring this regimen through the last stage of testing, has begun.
PaMZ is a three-drug regimen comprised of two candidate drugs that are not yet licensed for use against TB: pretomanid (Pa), formerly known as PA-824, ...

Chemical changes that occur in tree leaves after being attacked by insects and mammals can impact nearby streams, which rely on fallen plant material as a food source, report scientists from the University of Chicago Department of Ecology and Evolution. The study, published March 17 in the journal Proceedings of the Royal Society B, shows how interactions between terrestrial and aquatic ecosystems are an essential part of understanding ecological responses to climate change.
Graduate student Sara Jackrel and Timothy Wootton, PhD, professor in the Department of Ecology ...
