Eye movements in binary food choice context: assessing the complexity of restaurant menus on virtue vs. vice foods

ABSTRACT This paper explores binary food choices through the lens of information load theory. We conducted two laboratory studies using the eye-tracking approach to understand the influence of the high menu complexity on visual attention for virtue versus vice food options. This paper also examined the moderating effect of time on the initial fixation. Our findings showed that the time duration taken to reach the first fixation influences binary food choices. This was evident when participants were tasked with selecting food options from a high menu complexity. Specifically, fixation duration is greater for virtue food than vice food in a high menu complexity context. However, no differences in fixation duration between vice and virtue foods were observed in low menu complexity. This study provides key insights into understanding how differences in menu complexity impact customers’ binary food choice decisions concerning vice and virtue foods.

Opt-out vaccination in school and daycare: Reconciling parental authority and obligations.

An increasing vaccine hesitancy among parents, which has resulted in insufficient rates of immunization, provides reason to reconsider childhood vaccination practices. Studies suggest that parents' decision-making process concerning whether to vaccinate their child is highly influenced by cognitive biases. These biases can be utilized to increase vaccination uptake via changes in the choice context. This article considers childhood vaccination programmes, which involve children being vaccinated in school or daycare unless their parents actively 'opt out'. We suggest that such programmes reconcile parents' decisional authority and vaccination duties. First, opt-out childhood vaccination based in schools or daycare centres are not disrespectful of parental authority. Second, the programme aligns the default setting with a moral obligation to vaccinate one's child that most parents have.

The Rank Length Effect

Rank lists vary in the number of items ranked on the list (e.g., top 5 vs. top 20 movies on IMDb), that is, the rank length. Across ten studies, including both field and laboratory experiments, the authors examine the influence of rank length on evaluations, willingness to pay, and choice. They document a novel rank length effect: The same ranked items elicit more positive judgments when the rank length is longer (vs. shorter), although the differences in judgments between the ranked items are smaller. This effect is driven both by consumers’ tendency to narrowly focus on the rank list and by the manner in which they map the rank list onto their mental number line. The rank length effect extends to willingness to pay, and choice. The authors explore three different kinds of choice contexts, discuss implications, and offer suggestions for future research.

Heterogeneity in choice models of addiction: the role of context.

Theories of addiction guide scientific progress, funding priorities, and policy development and ultimately shape how people experiencing or recovering from addiction are perceived and treated. Choice theories of addiction are heterogenous, and different models have divergent implications. This breeds confusion among laypeople, scientists, practitioners, and policymakers and reduces the utility of robust findings that have the potential to reduce the global burden of addiction-associated harms. Here we differentiate classes of choice models and articulate a novel framing for a class of addiction models, called contextual models, which share as a first principle the influence of the environment and other contextual factors on behavior within discrete choice contexts. These models do not assume that all choice behaviors are voluntary, but instead that both proximal and distal characteristics of the choice environment-and particularly the benefits and costs of both drug use and non-drug alternatives-can influence behavior in ways that are outside of the awareness of the individual. From this perspective, addiction is neither the individual's moral failing nor an internal uncontrollable urge but rather is the result of environmental contingencies that reinforce the behavior. Contextual models have implications for guiding research, practice, and policy, including identification of novel target mechanisms while also improving existing interventions.

Electric vehicle public charging choices: a qualitative investigation

ABSTRACT Understanding how potential and existing electric vehicle users choose public charging is critical for the development of public-charging infrastructure. This study employs a qualitative approach guided by stated choice tasks to examine the decision-making processes regarding public charging. Through 20 interviews of existing and potential EV users in the UK, thematic analysis of responses pointed towards three areas: the choice context, attribute non-attendance and payment method. Participants sought detailed information about the circumstances under which they had to charge their vehicles. Attribute non-attendance meant that some participants paid more attention to specific attributes than others (e.g. location, price). Responses around the payment method pointed towards differences in relation to personal attitudes. This evidence suggests that charging choices are context-dependent, choices may be guided by specific attributes and individual attitudes play a role in these choices. These are also important considerations when designing a large-scale survey involving choice experiments and public charging.

Correspondence between the alcohol-P3 event-related potential and alcohol reward phenotypes among young adults.

Behavioral economic theory suggests that the value of alcohol depends upon elements of the choice context, such that increasing constraints on alternatives (e.g., price) or increasing the benefits of alcohol (e.g., social context) may result in greater likelihood of heavy drinking. The P3 event-related potential elicited by alcohol-related cues, a proposed marker of incentive salience, may be an electrophysiological parallel for behavioral economic alcohol demand. However, these indices have not been connected in prior research, and studies typically do not disaggregate social influences in the context of alcohol cue reactivity. The current study recruited heavy drinking young adults (N = 81) who completed measures of alcohol use and alcohol demand, in addition to a 2 (social/nonsocial) × 2 (alcohol/nonalcohol) visual oddball task to elicit the P3. In multilevel models controlling for demographic characteristics, P3 reactivity was greater to alcohol (p < 0.001) and social (p < 0.001) cues than to nonalcohol and nonsocial cues, but without a significant interaction. Higher alcohol consumption (p = 0.02) and lower elasticity of demand (p = 0.01) were associated with greater P3 response to alcohol than nonalcohol cues. The results highlight a brain-behavior connection that may be an important marker for alcohol reward across units of analysis and may be sensitive to changes in the economic choice contexts that influence the likelihood of alcohol use.

A social learning primacy trend in mate-copying: an experiment in Drosophila melanogaster.

Social learning is learning from the observation of how others interact with the environment. However, in nature, individuals often need to process serial social information and may favour either the most recent information (recency bias), constantly updating knowledge to match the environment, or the information that appeared first in the series (primacy bias), which may slow down adjustment to environmental change. Mate-copying is a widespread form of social learning in a mate choice context related to conformity in mate choice, and where a naive individual develops a preference for a given mate (or mate phenotype) seen being chosen by conspecifics. Mate-copying is documented in most vertebrate taxa and in the fruit fly Drosophila melanogaster. Here, we tested experimentally whether female fruit flies show a primacy or a recency bias by presenting pictures of a female copulating with one of two contrastingly coloured male phenotypes. We found that after two sequential contradictory demonstrations, females show a tendency to prefer males of the phenotype preferred in the first demonstration, suggesting that mate-copying in D. melanogaster is not based on the most recently observed mating and may be influenced by a form of primacy bias.

Unwritten ground rules of school choice: Excavating capital as a regulator of access to educational goods

District leaders in school choice contexts tend to overlook the many hidden costs of selecting schools in terms of mobility, time, liquidity, and labor. Meanwhile, a body of literature on school choice policies and cultural, social, and political capital shows that middle-class parents use the resources they possess to get the school access they want. In this study, I critically examine the complex interplay between school choice policies and forms of capital. This analysis extends our empirical understanding of the political dimensions of families’ school choices—the way parent resources, relationships, and strategies determine “who gets what, when, and how” (Laswell, 1936) in terms of schooling opportunities, and way these policies help structure disproportionate school access. By attending to families’ affordances of cultural, social, and political capital in studies of school choice, authorities may be more likely to design choice supports that address some demand-side inequities.

A new mRNA structure prediction based approach to identifying improved signal peptides for bone morphogenetic protein 2

BackgroundSignal peptide (SP) engineering has proven able to improve production of many proteins yet is a laborious process that still relies on trial and error. mRNA structure around the translational start site is important in translation initiation and has rarely been considered in this context, with recent improvements in in silico mRNA structure potentially rendering it a useful predictive tool for SP selection. Here we attempt to create a method to systematically screen candidate signal peptide sequences in silico based on both their nucleotide and amino acid sequences. Several recently released computational tools were used to predict signal peptide activity (SignalP), localization target (DeepLoc) and predicted mRNA structure (MXFold2). The method was tested with Bone Morphogenetic Protein 2 (BMP2), an osteogenic growth factor used clinically for bone regeneration. It was hoped more effective BMP2 SPs could improve BMP2-based gene therapies and reduce the cost of recombinant BMP2 production.ResultsAmino acid sequence analysis indicated 2,611 SPs from the TGF-β superfamily were predicted to function when attached to BMP2. mRNA structure prediction indicated structures at the translational start site were likely highly variable. The five sequences with the most accessible translational start sites, a codon optimized BMP2 SP variant and the well-established hIL2 SP sequence were taken forward to in vitro testing. The top five candidates showed non-significant improvements in BMP2 secretion in HEK293T cells. All showed reductions in secretion versus the native sequence in C2C12 cells, with several showing large and significant decreases. None of the tested sequences were able to increase alkaline phosphatase activity above background in C2C12s. The codon optimized control sequence and hIL2 SP showed reasonable activity in HEK293T but very poor activity in C2C12.ConclusionsThese results support the use of peptide sequence based in silico tools for basic predictions around signal peptide activity in a synthetic biology context. However, mRNA structure prediction requires improvement before it can produce reliable predictions for this application. The poor activity of the codon optimized BMP2 SP variant in C2C12 emphasizes the importance of codon choice, mRNA structure, and cellular context for SP activity.

Putting the Choice in Choice Tasks: Incorporating Preference Elicitation Tasks in Health Preference Research.

Choice-based preference elicitation methods such as the discrete choice experiment (DCE) present hypothetical choices to respondents, with an expectation that these hypothetical choices accurately reflect a 'real world' health-related decision context and that consequently the choice data can be held to be a true representation of the respondent's health or treatment preferences. For this to be the case, careful consideration needs to be given to the format of the choice task in a choice experiment. The overarching aim of this paper is to highlight important aspects to consider when designing and 'setting up' the choice tasks to be presented to respondents in a DCE. This includes the importance of considering the potential impact of format (e.g. choice context, choice set presentation and size) as well as choice set content (e.g. labelled and unlabelled choice sets and inclusion of reference alternatives) and choice questions (stated choice versus additional questions designed to explore complete preference orders) on the preference estimates that are elicited from studies. We endeavoure to instil a holistic approach to choice task design that considers format alongside content, experimental design and analysis.

On the advantages and disadvantages of choice: future research directions in choice overload and its moderators.

Researchers investigating the psychological effects of choice have provided extensive empirical evidence that having choice comes with many advantages, including better performance, more motivation, and greater life satisfaction and disadvantages, such as avoidance of decisions and regret. When the decision task difficulty exceeds the natural cognitive resources of human mind, the possibility to choose becomes more a source of unhappiness and dissatisfaction than an opportunity for a greater well-being, a phenomenon referred to as choice overload. More recently, internal and external moderators that impact when choice overload occurs have been identified. This paper reviews seminal research on the advantages and disadvantages of choice and provides a systematic qualitative review of the research examining moderators of choice overload, laying out multiple critical paths forward for needed research in this area. We organize this literature review using two categories of moderators: the choice environment or context of the decision as well as the decision-maker characteristics.

Effects of public policy interventions for environmentally sustainable food consumption: a systematic map of available evidence

BackgroundThe global food system is inflicting substantial environmental harm, necessitating a shift towards more environmentally sustainable food consumption practices. Policy interventions, for example, information campaigns, taxes and subsidies and changes in the choice context are essential to stimulate sustainable change, but their effectiveness in achieving environmental goals remains inadequately understood. Existing literature lacks a comprehensive synthesis of evidence on the role of public policies in promoting sustainable food consumption. Our systematic map addressed this gap by collecting and categorising research evidence on public policy interventions aimed at establishing environmentally sustainable food consumption patterns, in order to answer the primary research question: What evidence exists on the effects of public policy interventions for achieving environmentally sustainable food consumption?MethodsSearches for relevant records (in English) were performed in WoS, Scopus, ASSIA, ProQuest Dissertation and Theses, EconLit, Google Scholar and in bibliographies of relevant reviews. A grey literature search was also performed on 28 specialist websites (searches were made in the original language of the webpages and publications in English, Swedish, Danish and Norwegian were eligible) and Google Scholar (search in English). Screening was performed at title/abstract and full-text levels, with machine learning-aided priority screening at title/abstract level. Eligibility criteria encompassed settings, interventions (public policies on sustainable food consumption), target groups and outcomes. No critical appraisal of study validity was conducted. Data coding covered bibliographic details, study characteristics, intervention types and outcomes. Evidence was categorised into intervention types and subcategories. Visual representation utilised bar plots, diagrams, heatmaps and an evidence atlas. This produced a comprehensive overview of effects of public policy interventions on sustainable food consumption patterns.Review findingsThe evidence base included 227 articles (267 interventions), with 92% of studies in high-income countries and only 4% in low-income countries. Quantitative studies dominated (83%), followed by mixed methods (16%) and qualitative studies (1%). Most interventions were information-based and 50% of reviewed studies looked at labels. Information campaigns/education interventions constituted 10% of the sample, and menu design changes and restriction/editing of choice context 8% each. Market-based interventions represented 13% of total interventions, of which two-thirds were taxes. Administrative interventions were rare (< 1%). Proxies for environmental impact (85%) were more frequent outcome measures than direct impacts (15%). Animal-source food consumption was commonly used (19%) for effects of interventions on, for example, greenhouse gas emissions. Most studies used stated preferences (61%) to evaluate interventions.ConclusionsThe literature assessing policies for sustainable food consumption is dominated by studies on non-intrusive policy instruments; labels, information campaigns, menu design changes and editing choice contexts. There is a strong need for research on sustainable food policies to leave the lab and enter the real world, which will require support and cooperation of public and private sector stakeholders. Impact evaluations of large-scale interventions require scaling-up of available research funding and stronger multidisciplinary research, including collaborations with industry and other societal actors. Future research in this field should also go beyond the European and North American context, to obtain evidence on how to counteract increasing environmental pressures from food consumption worldwide.

Blurring Reality and Blurring Gender: Fashion and Attire in Virginia Woolf’s Orlando

Abstract The aim of this paper is to investigate the interplay between narrative style, gender and fashion within Woolf’s Orlando. This study delves into how Woolf’s use of a biographical narrative approach in a fantasy novel facilitates the exploration of gender stereotypes and their subsequent blurring. In this regard, through a meticulous analysis of Orlando, Woolf ingeniously employs the biographical style to transcend traditional literary boundaries. This stylistic choice allows for a deliberate blurring of reality and fantasy, prompting a transformative narrative experience. Within this narrative framework, the significance of fashion and attire emerges as essential tools for challenging conventional gender norms: clothing serves as a powerful vehicle for destabilising preconceived notions of gender. By situating Orlando’s fluid identity and evolving gender presentation within the context of clothing choices, the novel portrays the malleability of gender constructs. The blurring of genders is skilfully intertwined with the blurring of reality, forging a narrative tapestry that offers profound insights into societal perceptions of identity. In conclusion, this paper illuminates how Woolf’s novel enables a thoughtprovoking exploration of gender stereotypes, ultimately advocating for a more inclusive and fluid understanding of identity through the lens of fashion and attire.

Salient Cues and Complexity

Important decisions are often complex, and existing evidence suggests that complexity can affect economic behavior. It is an open question, however, exactly when and how complexity matters. We hypothesize that salient cues—standing out in the choice context—mitigate the effect of complexity on choices. We theoretically develop and experimentally test this hypothesis in the context of portfolio selection. We find that, in both simple and complex problems, subjects seek highly right-skewed portfolios, which have an extreme and salient upside, and avoid highly left-skewed portfolios with an extreme and salient downside. Complexity does affect, however, choices among symmetric portfolios, which have neither a salient upside nor downside. Absent a salient cue, subjects diversify naively. Evidence on response times and memory supports our salience-based explanation. This paper was accepted by Ilia Tsetlin, behavioral economics and decision analysis.

Perspective: Promoting Healthy Aging through Nutrition: A Research Centers Collaborative Network Workshop Report

Within 20 y, the number of adults in the United States over the age of 65 y is expected to more than double and the number over age 85 y is expected to more than triple. The risk for most chronic diseases and disabilities increases with age, so this demographic shift carries significant implications for the individual, health care providers, and population health. Strategies that delay or prevent the onset of age-related diseases are becoming increasingly important. Although considerable progress has been made in understanding the contribution of nutrition to healthy aging, it has become increasingly apparent that much remains to be learned, especially because the aging process is highly variable. Most federal nutrition programs and nutrition research studies define all adults over age 65 y as “older” and do not account for physiological and metabolic changes that occur throughout older adulthood that influence nutritional needs. Moreover, the older adult population is becoming more racially and ethnically diverse, so cultural preferences and other social determinants of health need to be considered. The Research Centers Collaborative Network sponsored a 1.5-d multidisciplinary workshop that included sessions on dietary patterns in health and disease, timing and targeting interventions, and health disparities and the social context of diet and food choice. The agenda and presentations can be found at https://www.rccn-aging.org/nutrition-2023-rccn-workshop. Here we summarize the workshop’s themes and discussions and highlight research gaps that if filled will considerably advance our understanding of the role of nutrition in healthy aging.

Zebra Finch Females Avoided the Scent of Males with Greater Body Condition

The role of chemical communication in the social relationships of birds is receiving growing attention, but our knowledge is still scarce compared to that of other taxa. Previous evidence suggests that chemical cues emitted by birds may carry information about their characteristics, which may be useful in the context of sexual selection. However, experimental studies are needed to investigate the role of bird chemical cues in signalling the quality of potential partners. We performed an experimental study aimed at disentangling whether the female Zebra Finches (Taeniopygia guttata), use chemical cues to assess the body condition of potential partners. We offered focal females (N = 28) the scent of two males differing in body condition (body mass/tarsus length ratio) (N = 28 scent donor males). Our results showed that females can assess the body condition of potential partners using olfaction. However, contrary to what should be expected in a mate choice context, females avoided the scent of males with greater body condition. Our results, therefore, suggest that, despite performing the study during the breeding period, social interactions may be mediating the avoidance of the scent of the male in better condition in this gregarious species, probably to avoid a conspecific competitor with better body condition.

Absolute and relative stability of loss aversion across contexts.

Individuals' decisions under risk tend to be in line with the notion that "losses loom larger than gains." This loss aversion in decision making is commonly understood as a stable individual preference that is manifested across different contexts. The presumed stability and generality, which underlies the prominence of loss aversion in the literature at large, has been recently questioned by studies reporting how loss aversion can disappear, and even reverse, as a function of the choice context. The present study investigated whether loss aversion reflects a trait-like attitude of avoiding losses or rather individuals' adaptability to different contexts. We report three experiments investigating the within-subject context sensitivity of loss aversion in a two-alternative forced-choice task. Our results show that the choice context can shift people's loss aversion, though somewhat inconsistently. Moreover, individual estimates of loss aversion are shown to have a considerable degree of stability. Altogether, these results indicate that even though the absolute value of loss aversion can be affected by external factors such as the choice context, estimates of people's loss aversion still capture the relative dispositions toward gains and losses across individuals.

Response to MHC-based olfactory cues in a mate choice context in two species of darter (Percidae: Etheostoma).

Mate choice is hypothesized to play an important role in maintaining high diversity at major histocompatibility complex (MHC) genes in vertebrates. Many studies have revealed that females across taxa prefer the scent of males with MHC genotypes different to their own. In this study we tested the "opposites-attract" hypothesis in two species of darter with known differences in female criteria used in mate choice: in the fantail darters (a paternal-care species), females prefer males with visual traits related to nest guarding and egg tending, while in rainbow darters (not a paternal-care species) female mate choice criteria are unknown. In dichotomous mate-choice trials, we presented females of both species with the scents of conspecific males with MHC class IIb genotypes that were either similar or dissimilar to that of the focal female. We evaluated the proportion of time each female spent with each male and calculated the average strength of female preference for both species. Female fantail darters demonstrated a preference for the scent of males with similar (rather than dissimilar) MHC genotypes, but this result was not statistically significant. Rainbow darter females showed no preference for the scent of males with similar or dissimilar MHC genotypes. Our results do not support the "opposites-attract" hypothesis in darters.

Drivers of school choice: Primary school selection in a free choice context

AbstractIn Italy, parents are free to choose the primary school for their children without restrictions imposed by catchment areas. This freedom of choice, inspired by quasi‐market mechanisms, aims to foster competition between schools and raise educational standards. Analysing the case of Milan using regression models and administrative data for the 2015–16 school year, we study the factors associated with the probability that parents choose a school different from the one closest to where they live. We focus on both push factors (the characteristics of local schools) and pull factors (the features of chosen schools). The findings indicate that parents select schools which have a lower proportion of immigrant pupils and higher socio‐economic status of the student body. On the other hand, school performance in standardised tests is not statistically associated with parents' decisions to opt out of local schools, nor does it emerge as a feature of the schools most likely to attract non‐local students after accounting for the socio‐economic composition of school intake. The resulting picture shows that affluent Italian parents implement avoidance strategies to avoid schools attended by a high proportion of immigrant or lower‐class students—with the potential of fostering segregation and concentrations of disadvantaged groups.
