Immediate Emotional States as Predictors of Risk Preferences

The interaction between emotions and cognitive processes has been one of the most investigated topics in last decades, with particular attention being paid to emotional influences in decision making. More recently, the processes by which people control and regulate their emotional states also became a topic of interest. The aim of the current study was to investigate how underlying immediate emotional states and communication of risk impact participants’ risk preferences for gambles. In one study we measured positive and negative immediate affective states and choice preferences under risk. Specifically, participants were presented with abstract monetary gambles in which they were required to choose between a probabilistic gain or loss and a certain option. We found that positive and negative emotional states as well as communication format of risk influenced behavioural patterns of preferences. Future research can build on these results and include emotion based parameters in decision making models

Are Personal Values Associated with Social Decisions? The Role of Self-Transcendence in Promoting Prosocial Outcomes

Social situations require people to make complex decisions, sometimes involving different outcomes for the self and others. The aim of this study is to investigate personal values as possible factors associated with a preference for more self-maximizing or cooperative choices. In an adult sample (N = 63), we assessed participants’ tendency towards prosocial or proself outcomes and 4 higher-order values, namely openness to change, conservation, self-transcendence, and self-enhancement. We expected self-transcendence to be positively associated with more prosocial orientations. Our result confirmed that self-transcendence was positively correlated with prosociality whereas no other higher-order values were associated with social values. Participants with increased self-transcendence also have an inclination towards more prosocial behaviors. Our data also revealed that inequality aversion was the primary motivation of prosocials, and this result was unrelated to gender effects or the personal values under investigation. Supporting the theory of basic individual values, our results show that the higher-order value of self-transcendence is a significant positive correlate of prosocial behaviors in a resources allocation task

A dose-ranging, parallel group, split-face, single-blind phase II study of light emitting diode-red light (LED-RL) for skin scarring prevention: study protocol for a randomized controlled trial.

BackgroundSkin fibrosis is a significant global health problem that affects over 100 million people annually and has a profoundly negative impact on quality of life. Characterized by excessive fibroblast proliferation and collagen deposition, skin fibrosis underlies a wide spectrum of dermatologic conditions ranging from pathologic scars secondary to injury (e.g., burns, surgery, trauma) to immune-mediated diseases. Effective anti-scarring therapeutics remain an unmet need, underscoring the importance of developing novel approaches to treat and prevent skin fibrosis. Our in vitro data show that light emitting diode-red light (LED-RL) can modulate key cellular and molecular processes involved in skin fibrosis. In two phase I clinical trials (STARS 1 and STARS 2), we demonstrated the safety and tolerability of LED-RL at fluences of 160 J/cm2 up to 480 J/cm2 on normal human skin.Methods/designCURES (Cutaneous Understanding of Red-light Efficacy on Scarring) is a dose-ranging, randomized, parallel group, split-face, single-blind, mock-controlled phase II study to evaluate the efficacy of LED-RL to limit post-surgical skin fibrosis in subjects undergoing elective mini-facelift surgery. Thirty subjects will be randomly allocated to three treatment groups to receive LED-RL phototherapy or temperature-matched mock irradiation (control) to either periauricular incision site at fluences of 160 J/cm2, 320 J/cm2, or 480 J/cm2. Starting one week post-surgery (postoperative days 4-8), treatments will be administered three times weekly for three consecutive weeks, followed by efficacy assessments at 30 days, 3 months, and 6 months. The primary endpoint is the difference in scar pliability between LED-RL-treated and control sites as determined by skin elasticity and induration measurements. Secondary outcomes include clinical and photographic evaluations of scars, 3D skin imaging analysis, histological and molecular analyses, and adverse events.DiscussionLED-RL is a therapeutic modality of increasing importance in dermatology, and has the potential to limit skin fibrosis clinically by decreasing dermal fibroblast activity and collagen production. The administration of LED-RL phototherapy in the early postoperative period may optimize wound healing and prevent excessive scarring. The results from this study may change the current treatment paradigm for fibrotic skin diseases and help to pioneer LED-RL as a safe, non-invasive, cost-effective, portable, at-home therapy for scars.Trial registrationClinicalTrials.gov, NCT03795116 .

Psychological Engagement in Choice and Judgment Under Risk and Uncertainty.

Theories of choice and judgment assume that agents behave rationally, choose the higher expected value option, and evaluate the choice consistently (Expected Utility Theory, Von Neumann, & Morgenstern, 1947). However, researchers in decision-making showed that human behaviour is different in choice and judgement tasks (Slovic & Lichtenstein, 1968; 1971; 1973). In this research, we propose that psychological engagement and control deprivation predict behavioural inconsistencies and utilitarian performance with judgment and choice. Moreover, we explore the influences of engagement and control deprivation on agent’s behaviours, while manipulating content of utility (Kusev et al., 2011, Hertwig & Gigerenzer 1999, Tversky & Kahneman, 1996) and decision reward (Kusev et al, 2013, Shafir et al., 2002)
