Ambiguity Aversion in Qualitative Contexts: a Vignette Study
Ambiguity aversion in qualitative contexts: A vignette study Joshua P. White Melbourne School of Psychological Sciences University of Melbourne Andrew Perfors Melbourne School of Psychological Sciences University of Melbourne Abstract Most studies of ambiguity aversion rely on experimental paradigms involv- ing contrived monetary bets. Thus, the extent to which ambiguity aversion is evident outside of such contexts is largely unknown, particularly in those contexts which cannot easily be reduced to numerical terms. The present work seeks to understand whether ambiguity aversion occurs in a variety of different qualitative domains, such as work, family, love, friendship, exercise, study and health. We presented participants with 24 vignettes and measured the degree to which they preferred risk to ambiguity. In a separate study we asked participants for their prior probability estimates about the likely outcomes in the ambiguous events. Ambiguity aversion was observed in the vast majority of vignettes, but at different magnitudes. It was predicted by gain/loss direction but not by the prior probability estimates (with the inter- esting exception of the classic Ellsberg ‘urn’ scenario). Our results suggest that ambiguity aversion occurs in a wide variety of qualitative contexts, but to different degrees, and may not be generally driven by unfavourable prior probability estimates of ambiguous events. Corresponding Author: Joshua P. White ([email protected]) AMBIGUITY AVERSION IN QUALITATIVE CONTEXTS: A VIGNETTE STUDY 2 Introduction The world is replete with the unknown, yet people generally prefer some types of ‘unknown’ to others. Here, an important distinction exists between risk and uncertainty. As defined by Knight (1921), risk is a measurable lack of certainty that can be represented by numerical probabilities (e.g., “there is a 50% chance that it will rain tomorrow”), while ambiguity is an unmeasurable lack of certainty (e.g., “there is an unknown probability that it will rain tomorrow”). -

Exploring Common Antecedents iii An Abstract of Exploring Common Antecedents of Three Related Decision Biases Jonathan E. Westfall Submitted as partial fulfillment of the requirements for The Doctor of Philosophy in Psychology The University of Toledo August 2009 “Decision making inertia” is a term loosely used to describe the similar nature of a variety of decision making biases that predominantly favor a decision to maintain one course of action over switching to a new course. Three of these biases, the sunk cost effect, status-quo bias, and inaction inertia are discussed here. Combining earlier work on strength of handedness and the sunk cost effect along with new findings regarding counterfactual thought, this work principally seeks to determine if counterfactual thought may drive the three decision biases of note while also analyzing common relationships between the biases, strength of handedness, and the variables of regret and loss aversion. Over a series of experiments, it was found that handedness differences did exist in the three biases discussed, that amount and type of counterfactuals generated did not predict choice within the status-quo bias, and that the remaining variables potentially thought to drive the biases presented did not link causally to them. -
Pleasantness Bias in Flashbulb Memories: Positive and Negative Flashbulb Memories of the Fall of the Berlin Wall Among East and West Germans
Memory & Cognition 2007, 35 (3), 565-577 Pleasantness bias in flashbulb memories: Positive and negative flashbulb memories of the fall of the Berlin Wall among East and West Germans ANNETTE BOHN AND DORTHE BERNTSEN Aarhus University, Aarhus, Denmark Flashbulb memories for the fall of the Berlin Wall were examined among 103 East and West Germans who considered the event as either highly positive or highly negative. The participants in the positive group rated their memories higher on measures of reliving and sensory imagery, whereas their memory for facts was less accurate than that of the participants in the negative group. The participants in the negative group had higher ratings on amount of consequences but had talked less about the event and considered it less central to their personal and national identity than did the participants in the positive group. In both groups, rehearsal and the centrality of the memory to the person’s identity and life story correlated positively with memory qualities. The results suggest that positive and negative emotions have different effects on the processing and long-term reten- tion of flashbulb memories.

MITIGATING COGNITIVE BIASES in RISK IDENTIFICATION: Practitioner Checklist for the AEROSPACE SECTOR
MITIGATING COGNITIVE BIASES IN RISK IDENTIFICATION: Practitioner Checklist for the AEROSPACE SECTOR Debra L. Emmons, Thomas A. Mazzuchi, Shahram Sarkani, and Curtis E. Larsen This research contributes an operational checklist for mitigating cogni- tive biases in the aerospace sector risk management process. The Risk Identification and Evaluation Bias Reduction Checklist includes steps for grounding the risk identification and evaluation activities in past project experiences through historical data, and emphasizes the importance of incorporating multiple methods and perspectives to guard against optimism and a singular project instantiation-focused view. The authors developed a survey to elicit subject matter expert judgment on the value of the check- list to support its use in government and industry as a risk management tool. The survey also provided insights on bias mitigation strategies and lessons learned. This checklist addresses the deficiency in the literature in providing operational steps for the practitioner to recognize and implement strategies for bias reduction in risk management in the aerospace sector.

Body Illusions for Mental Health: a Systematic Review
Body illusions for mental health: a systematic review Marta Matamala-Gomez1, Antonella Maselli2, Clelia Malighetti3, Olivia Realdon1, Fabrizia Mantovani1, Giuseppe Riva3,4 1 University of Milano-Bicocca, "Riccardo Massa" Department of Human Sciences for Education, Milan, Italy. 2 Institute of Cognitive Sciences and Technologies (ISTC), National Research Council (CNR), Rome, Italy. 3 Department of Psychology, Catholic University of Milan, Milan, Italy. 4 Applied Technology for Neuro-Psychology Laboratory, Istituto Auxologico Italiano, IRCCS, Milan, Italy. Corresponding author: Marta Matamala-Gomez [email protected] Abstract Body illusions (BIs) refer to altered perceptual states where the perception of the self-body significantly deviates from the configuration of the physical body, for example, in aspects like perceived size, shape, posture, location, and sense of ownership. Different established experimental paradigms allow to temporarily induce such altered perceptual states in a predictable and systematic manner. Even though there is evidence demonstrating the use of BIs in clinical neuroscience, to our knowledge, this is the first systematic review evaluating the effectiveness of BIs in healthy and clinical populations. This systematic review examined the use of BIs in the healthy and clinical populations, and review how BIs can be adopted to enhance mental health in different mental illness conditions. The systematic review was conducted following the PRISMA guidelines. Of the 8086 studies identified, 189 studies were included for full-text analyses. Seventy-seven studies used BIs in clinical populations. Most of the studies using BIs with clinical populations used body illusions toward a body part, modulating the external aspects of body representation. Even though clinical studies showed the positive effects of BIs to improve mental illness conditions, future technologies using BIs targeting both the external (exteroceptive) and the internal (interoceptive) aspects of body representations can further improve the efficacy of this approach. -
Elaborative Encoding, the Ancient Art of Memory, and the Hippocampus
View metadata, citation and similar papers at core.ac.uk brought to you by CORE BEHAVIORAL AND BRAIN SCIENCES (2013) 36, 589–659 provided by RERO DOC Digital Library doi:10.1017/S0140525X12003135 Such stuff as dreams are made on? Elaborative encoding, the ancient art of memory, and the hippocampus Sue Llewellyn Faculty of Humanities, University of Manchester, Manchester M15 6PB, United Kingdom http://www.humanities.manchester.ac.uk [email protected] Abstract: This article argues that rapid eye movement (REM) dreaming is elaborative encoding for episodic memories. Elaborative encoding in REM can, at least partially, be understood through ancient art of memory (AAOM) principles: visualization, bizarre association, organization, narration, embodiment, and location. These principles render recent memories more distinctive through novel and meaningful association with emotionally salient, remote memories. The AAOM optimizes memory performance, suggesting that its principles may predict aspects of how episodic memory is configured in the brain. Integration and segregation are fundamental organizing principles in the cerebral cortex. Episodic memory networks interconnect profusely within the cortex, creating omnidirectional “landmark” junctions. Memories may be integrated at junctions but segregated along connecting network paths that meet at junctions. Episodic junctions may be instantiated during non–rapid eye movement (NREM) sleep after hippocampal associational function during REM dreams. Hippocampal association involves relating, binding, and integrating episodic memories into a mnemonic compositional whole. This often bizarre, composite image has not been present to the senses; it is not “real” because it hyperassociates several memories. During REM sleep, on the phenomenological level, this composite image is experienced as a dream scene. -

Howard, and Ann-Marie Golden University of Oxford University of Cambridge Tim Dalgleish University of Cambridge and Cambridgeshire and Peterborough NHS Foundation Trust In mentally healthy individuals, autobiographical memory is typically biased toward positive events, which may help to maintain psychological well-being. Our aim was to assess a range of important positive memory biases in the mentally healthy and explore the possibility that these biases are mitigated in those with mental health problems. We administered a novel recall paradigm that required recollection of multiple good and bad past events (the Good Day–Bad Day task) to healthy and depressed individuals. This allowed us to explore differences in memory category fluency (i.e., the ability to generate integrated sets of associated events) for positive and negative memories, along with memory specificity, and fading affect bias—a greater reduction in the intensity of memory-related affect over time for negative versus positive events. We found that healthy participants demonstrated superior category fluency for positive relative to negative events but that this effect was absent in depressed participants. Healthy participants exhibited a strong fading affect bias that was significantly mitigated, although still present, in depression.
