Training Anchoring and Representativeness Bias Mitigation Through a Digital Game

Objective. Humans systematically make poor decisions because of cognitive biases. Can digital games train people to avoid cognitive biases? The goal of this study is to investigate the affordance of different educational media in training people about cognitive biases and to mitigate cognitive biases within their decision-making processes. Method. A between-subject experiment was conducted to compare a digital game, a traditional slideshow, and a combined condition in mitigating two types of cognitive biases: anchoring bias and representativeness bias. We measured both immediate effects and delayed effects after four weeks. Results. The digital game and slideshow conditions were effective in mitigating cognitive biases immediately after the training, but the effects decayed after four weeks. By providing the basic knowledge through the slideshow, then allowing learners to practice bias-mitigation techniques in the digital game, the combined condition was most effective at mitigating the cognitive biases both immediately and after four weeks.This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Mitigation of Cognitive Bias with a Serious Game: Two Experiments Testing Feedback Timing and Source

One of the benefits of using digital games for education is that games can provide feedback for learners to assess their situation and correct their mistakes. We conducted two studies to examine the effectiveness of different feedback design (timing, duration, repeats, and feedback source) in a serious game designed to teach learners about cognitive biases. We also compared the digital game-based learning condition to a professional training video. Overall, the digital game was significantly more effective than the video condition. Longer durations and repeats improve the effects on bias-mitigation. Surprisingly, there was no significant difference between just-in-time feedback and delayed feedback, and computer-generated feedback was more effective than feedback from other players

Listening in the dark: why we need stories of people living with severe and enduring anorexia nervosa

A bold step forward in our approach to Severe and Enduring Anorexia Nervosa invites new paradigms for research and practice. It provides an opportunity for us to explore fault lines, both in our communities of practice and the social structures that inform them. This paper serves to question the medical metaphors on which treatment has been based, in favour of alternative perspectives that resonate more clearly with the lived experience of those for whom it has failed. We invite the consideration of alternative metaphors, which can disrupt the notion of heroic patients (and therapists), mediate against acts of self-silencing and sensitising us to more radical acts of listening. Beyond the randomised trials and manuals it is time for us to listen to the realities of suffering, the minutiae of resistance and the life that can still be lived

Ecosystem Resilience and Threshold Response in the Galápagos Coastal Zone

Background: The Intergovernmental Panel on Climate Change (IPCC) provides a conservative estimate on rates of sea-level rise of 3.8 mm yr⁻¹ at the end of the 21st century, which may have a detrimental effect on ecologically important mangrove ecosystems. Understanding factors influencing the long-term resilience of these communities is critical but poorly understood. We investigate ecological resilience in a coastal mangrove community from the Galápagos Islands over the last 2700 years using three research questions: What are the 'fast and slow' processes operating in the coastal zone? Is there evidence for a threshold response? How can the past inform us about the resilience of the modern system?Methodology/Principal Findings: Palaeoecological methods (AMS radiocarbon dating, stable carbon isotopes (δ13C)) were used to reconstruct sedimentation rates and ecological change over the past 2,700 years at Diablas lagoon, Isabela, Galápagos. Bulk geochemical analysis was also used to determine local environmental changes, and salinity was reconstructed using a diatom transfer function. Changes in relative sea level (RSL) were estimated using a glacio-isostatic adjustment model. Non-linear behaviour was observed in the Diablas mangrove ecosystem as it responded to increased salinities following exposure to tidal inundations. A negative feedback was observed which enabled the mangrove canopy to accrete vertically, but disturbances may have opened up the canopy and contributed to an erosion of resilience over time. A combination of drier climatic conditions and a slight fall in RSL then resulted in a threshold response, from a mangrove community to a microbial mat.Conclusions/Significance: Palaeoecological records can provide important information on the nature of non-linear behaviour by identifying thresholds within ecological systems, and in outlining responses to 'fast and slow' environmental change between alternative stable states. This study highlights the need to incorporate a long-term ecological perspective when designing strategies for maximizing coastal resilience.</p

Socioecological influences on concussion reporting by NCAA Division 1 athletes in high-risk sports.

Concussion among athletes is an issue of growing concern, with efforts underway to improve detection, diagnosis, and treatment. Success depends on communication by athletes, as brain-related symptoms are often not outwardly visible. Education programs to increase reporting behavior have not been successful to date. In accordance with the socioecological approach to health, we argue that multiple levels of influence on student athletes must be addressed, and report a multi-dimensional, mixed-methods research project conducted to identify possible points of intervention into changing the culture of concussion-injury reporting among collegiate athletes. Using quantitative, qualitative and interpretive methods, we examine the individual-level vested interests athletes have in reporting or not reporting concussion symptoms, and how these interests interact with community-level team culture and interpersonal relationships, and social-level cultural narratives to influence concussion-reporting behavior. Our findings confirm the viability of this approach, identifying immediacy, separation of responsibility and pain-enduring story systems as particularly salient elements. We conclude that competing performance versus safety value structures, reflected in cultural narratives and team culture, create mixed-messages for athletes, which are resolved in favor of performance because athletes perceive concussion injuries to be of low immediacy

Discovery of Novel Viruses in <i>Culicoides</i> Biting Midges in Chihuahua, Mexico

Biting midges (Culicoides) are vectors of many pathogens of medical and veterinary importance, but their viromes are poorly characterized compared to certain other hematophagous arthropods, e.g., mosquitoes and ticks. The goal of this study was to use metagenomics to identify viruses in Culicoides from Mexico. A total of 457 adult midges were collected in Chihuahua, northern Mexico, in 2020 and 2021, and all were identified as female Culicoides reevesi. The midges were sorted into five pools and homogenized. An aliquot of each homogenate was subjected to polyethylene glycol precipitation to enrich for virions, then total RNA was extracted and analyzed by unbiased high-throughput sequencing. We identified six novel viruses that are characteristic of viruses from five families (Nodaviridae, Partitiviridae, Solemoviridae, Tombusviridae, and Totiviridae) and one novel virus that is too divergent from all classified viruses to be assigned to an established family. The newly discovered viruses are phylogenetically distinct from their closest known relatives, and their minimal infection rates in female C. reevesi range from 0.22 to 1.09. No previously known viruses were detected, presumably because viral metagenomics had never before been used to study Culicoides from the Western Hemisphere. To conclude, we discovered multiple novel viruses in C. reevesi from Mexico, expanding our knowledge of arthropod viral diversity and evolution

Memoria general del primer curso-taller: "Enfoques biotecnológicos para abordar enfermedades emergentes y re-emergentes transmitidas por mosquitos y garrapatas en el Noroeste de México". Cd. Juárez, Chihuahua, 2019

Las enfermedades transmitidas por artrópodos son una preocupación creciente de salud pública a nivel mundial, ya que, por factores antropogénicos, cada año los casos aumentan con tendencia exponencial. Estas enfermedades son transmitidas a los vertebrados por artrópodos hematófagos, entre los que destacan los mosquitos y garrapatas. Algunas de estas enfermedades, son el dengue, Zika, paludismo, filariasis y rickettsiosis. Debido a las condiciones fisiográficas, económicas y demográficas, México, incluyendo su zona noroeste, es una región donde estas enfermedades presentan ciclos activos de transmisión, generando cada vez estadísticas mas altas de incidencia y prevalencia. En el estado de Chihuahua, la información de estas enfermedades es muy escasa, y aunque se han realizado pocos trabajos donde ha sido detectada la presencia de arbovirus y rickettsiosis, estos estudios no han sido sistemáticos y representativos. En este contexto, se planteo la idea de realizar por primera vez en la Universidad Autónoma de Ciudad Juárez, un curso taller que tuviera como objetivo el dar a conocer, de manera teórica y practica, cuales son las herramientas biotecnológicas actuales y más precisas que se utilizan a nivel mundial en e diagnostico y para prevenir y anticipar la emergencia de mencionadas enfermedades. Este evento fue titulado “Enfoques biotecnológicos para abordar enfermedades emergentes y reemergentes transmitidas por mosquitos y garrapatas en el Noroeste de México”, y patrocinado por el Consejo Nacional de Ciencia y Tecnología (No. proyecto: 299242) en el marco de su convocatoria 2019 del Programa para Actividades Científicas, Tecnológicas y de Innovación (PACTI). Este curso taller se llevó a cabo los días 14, 15 y 22 de noviembre del 2019 en las instalaciones del Instituto de Ciencias Biomédicas de la Universidad Autónoma de Ciudad Juárez (ICB-UACJ), en Cd. Juárez, Chihuahua, México
