The current study explored how drivers managed the cognitive load of negotiating roundabouts. One hundred fifty-five undergraduates at a large university in the southeastern United States were recruited. Participants were given some training on driving rules concerning roundabouts and were then presented with a 25 question, multiple-choice test that served as a check on learning. The participants who passed the learning check were then presented with 80 visual stimuli of driving situations commonly encountered at roundabouts. The stimuli were presented in Qualtrics as seven traffic situations that were randomized. Results supported the hypothesis that pedestrians are not noticed at roundabouts a significant amount of time making the pedestrian/automobile interaction at roundabouts a safety hazard. Participants failed to notice pedestrians most often in roundabout entering vignettes but also failed to notice pedestrians in roundabout exiting vignettes. Results suggest participants did not notice pedestrians attempting to cross the street in crosswalks at roundabouts. Additional research is needed to study how to increase visibility of pedestrian crossing in roundabouts. The findings of this study will raise awareness of the increased need for pedestrian safety measures at roundabouts. }, number={1}, journal={Proceedings of the Human Factors and Ergonomics Society Annual Meeting}, publisher={SAGE Publications}, author={Clark, Ralph O and Mayhorn, Christopher B.}, year={2022}, month={Sep}, pages={1746–1750} } @inproceedings{mcgough_mayhorn_2022, title={Cognitive factors influencing sustained attention in a college sample}, booktitle={Proceedings of the Human Factors and Ergonomics Society 66th Annual Meeting}, author={McGough, O. and Mayhorn, C.B.}, year={2022} } @misc{masot_cox_mold_sund-levander_tingstrom_christelle boersema_botigue_daltrey_hughes_mayhorn_et al._2022, title={Decision support-tools for early detection of infection in older people (aged> 65 years): a scoping review}, volume={22}, ISSN={["1471-2318"]}, DOI={10.1186/s12877-022-03218-w}, abstractNote={Abstract Background Infection is more frequent, and serious in people aged > 65 as they experience non-specific signs and symptoms delaying diagnosis and prompt treatment. Monitoring signs and symptoms using decision support tools (DST) is one approach that could help improve early detection ensuring timely treatment and effective care. Objective To identify and analyse decision support tools available to support detection of infection in older people (> 65 years). Methods A scoping review of the literature 2010–2021 following Arksey and O’Malley (2005) framework and PRISMA-ScR guidelines. A search of MEDLINE, Cochrane, EMBASE, PubMed, CINAHL, Scopus and PsycINFO using terms to identify decision support tools for detection of infection in people > 65 years was conducted, supplemented with manual searches. Results Seventeen papers, reporting varying stages of development of different DSTs were analysed. DSTs largely focussed on specific types of infection i.e. urine, respiratory, sepsis and were frequently hospital based (n = 9) for use by physicians. Four DSTs had been developed in nursing homes and one a care home, two of which explored detection of non- specific infection. Conclusions DSTs provide an opportunity to ensure a consistent approach to early detection of infection supporting prompt action and treatment, thus avoiding emergency hospital admissions. A lack of consideration regarding their implementation in practice means that any attempt to create an optimal validated and tested DST for infection detection will be impeded. This absence may ultimately affect the ability of the workforce to provide more effective and timely care, particularly during the current covid-19 pandemic. }, number={1}, journal={BMC GERIATRICS}, author={Masot, Olga and Cox, Anna and Mold, Freda and Sund-Levander, Martha and Tingstrom, Pia and Christelle Boersema, Geertien and Botigue, Teresa and Daltrey, Julie and Hughes, Karen and Mayhorn, Christopher B. and et al.}, year={2022}, month={Jul} } @article{wilson_mayhorn_2022, title={Examination of Within-Headset Sports Media Experiences}, volume={66}, ISSN={2169-5067 1071-1813}, url={http://dx.doi.org/10.1177/1071181322661085}, DOI={10.1177/1071181322661085}, abstractNote={ With the many varied options for media presentation available within virtual reality devices today, it is important to start comparing these different formats to determine how different they are from each other.

Participants rated trust and reliance on VA after viewing medication labels and hearing recommendations from male and female agents with varying pitch. Results suggest agents perceived as female were rated as more trustworthy, while vocal pitch did not significantly influence trust. However, a trend of lower reliance with increasing pitch was observed. Additionally, participants relied significantly more on VA advice than medication labels when making decisions. Post-hoc analyses revealed trust and reliance primarily varied between participants. Pitch and gender explained only a small portion of within-participant variance.

Potential target audiences for warnings can be very diverse and may include health professionals such as physicians or nurses as well as members of the public. In general, warnings serve three distinct purposes. First, warnings are used to improve health and safety by reducing the likelihood of events that might result in personal injury, disease, death, or property damage. Second, they are used to communicate important safety-related information. In general, warnings likely to be effective should include a description of the hazard, instructions on how to avoid the hazard, and an indication of the severity of consequences that might occur as a result of not complying with the warning. Third, warnings are used to promote safe behavior and reduce unsafe behavior. Various regulatory agencies within the United States and around the globe may take an active role in determining the content and formatting of warnings. The Communication-Human Information Processing (C-HIP) model was developed to describe the processes involved in how people interact with warnings and other information. This framework employs the basic stages of a simple communication model such that a warning message is sent from one entity (source) through some channel(s) to another (receiver). Once warning information is delivered to the receiver, processing may be initiated, and if not impeded, will continue through several stages including attention switch, attention maintenance, comprehension and memory, beliefs and attitudes, and motivation, possibly ending in compliance behavior. Examples of health-related warnings are presented to illustrate concepts.

As phishing emails continue to infiltrate users' mailboxes, what social engineering techniques are the phishers using to successfully persuade victims into releasing sensitive information? Cialdini's [2007] six principles of persuasion (authority, social proof, liking/similarity, commitment/consistency, scarcity, and reciprocation) have been linked to elements of phishing emails [Akbar 2014; Ferreira, & Lenzini 2015]; however, the findings have been conflicting. Authority and scarcity were found as the most common persuasion principles in 207 emails obtained from a Netherlands database [Akbar 2014], while liking/similarity was the most common principle in 52 personal emails available in Luxemborg and England [Ferreira et al. 2015]. The purpose of this study was to examine the persuasion principles present in emails available in the United States over a period of five years. Two reviewers assessed eight hundred eighty-seven phishing emails from Arizona State University, Brown University, and Cornell University for Cialdini's six principles of persuasion. Each email was evaluated using a questionnaire adapted from the Ferreira et al. [2015] study. There was an average agreement of 87% per item between the two raters. Spearman's Rho correlations were used to compare email characteristics over time. During the five year period under consideration (2010--2015), the persuasion principles of commitment/consistency and scarcity have increased over time, while the principles of reciprocation and social proof have decreased over time. Authority and liking/similarity revealed mixed results with certain characteristics increasing and others decreasing. The commitment/consistency principle could be seen in the increase of emails referring to elements outside the email to look more reliable, such as Google Docs or Adobe Reader (rs(850) = .12, p =.001), while the scarcity principle could be seen in urgent elements that could encourage users to act quickly and may have had success in eliciting a response from users (rs(850) = .09, p =.01). Reciprocation elements, such as a requested reply, decreased over time (rs(850) = -.12, p =.001). Additionally, the social proof principle present in emails by referring to actions performed by other users also decreased (rs(850) = -.10, p =.01). Two persuasion principles exhibited both an increase and decrease in their presence in emails over time: authority and liking/similarity. These principles could increase phishing rate success if used appropriately, but could also raise suspicions in users and decrease compliance if used incorrectly. Specifically, the source of the email, which corresponds to the authority principle, displayed an increase over time in educational institutes (rs(850) = .21, p <.001), but a decrease in financial institutions (rs(850) = -.18, p <.001). Similarly, the liking/similarity principle revealed an increase over time of logos present in emails (rs(850) = .18, p <.001) and decrease in service details, such as payment information (rs(850) = -.16, p <.001). The results from this study offer a different perspective regarding phishing. Previous research has focused on the user aspect; however, few studies have examined the phisher perspective and the social psychological techniques they are implementing. Additionally, they have yet to look at the success of the social psychology techniques.

This information could provide a basis for future research on how mental models could be used to determine phishing vulnerability and the effectiveness of phishing training.}, journal={Proceedings of the 2015 Symposium and Bootcamp on the Science of Security}, publisher={ACM}, author={Zielinska, Olga and Welk, Allaire and Mayhorn, Christopher B. and Murphy-Hill, Emerson}, year={2015}, month={Apr} } @article{zielinska_mayhorn_2015, title={Manipulating the Display of Probability Rates on Web Health Searches}, volume={59}, ISSN={2169-5067 1071-1813}, url={http://dx.doi.org/10.1177/1541931215591116}, DOI={10.1177/1541931215591116}, abstractNote={The Internet offers many benefits to people seeking health information, such as the convenience of accessing information at any time, and the protection of viewing information anonymously; however, such information is unregulated and can be misinterpreted (Raine et al., 2000; Starcevic & Berle, 2013). Escalation, the observed increase in medical severity of search terms within a single search session, could occur. For example, escalation occurs when an initial search for “headache” leads to a later search for “brain tumor”. Researchers have recommended including incidence rates to reduce escalation; however, this phenomenon has yet to be tested empirically. The purpose of the current research is to investigate the effects of adding probability rates to Internet health search results. One-hundred-and-fifty undergraduates were randomly assigned to one of three presentation groups (control, pictorial, and numeric) where they evaluated four search results pages. Incidence rates were not displayed in the control whereas participants in the pictorial condition saw incidence rates displayed as bar graphs and those in the numeric condition saw incidence rates displayed as percentages. Escalation was evaluated using the severity and susceptibility measures from the Risk Behavior Diagnosis Scale. Severity was defined as the magnitude of harm expected from a threat or the significance or seriousness of a threat (Witte, Meyer, & Martell, 2001). The Risk Behavior Diagnosis Scale evaluated severity in three questions: (Symptom) is a serious threat; (Symptom) is harmful; and (Symptom) is a severe threat. Susceptibility is the likelihood that a specific person will experience a threat, the degree of vulnerability, or risk of experience a threat. In the current study, three questions were used to assess susceptibility: If I have (symptom), I am at risk for having (serious condition); It is likely that I have (serious condition) if I experience (symptom); (Symptom) is nothing to worry about. Four symptoms were evaluated and each symptom was paired with four conditions: two benign and two serious. Results indicated that participants believed symptoms were more severe after reviewing search result pages than before reviewing search result pages ( p<.001); however, there were no display group differences in perceived severity. Participants also believed that they were the most susceptible to benign conditions when incidence rates were shown numerically, followed by pictorially, and the least susceptible when there were no incidence rates present. The numeric group was significantly higher than the control group ( p=.002); however, there were no differences between the numeric and pictorial group, and between the control and pictorial group ( p<.10). Similarly in the serious condition, the highest ratings were in the numeric group, followed by pictorial, and the lowest perceived susceptibility was in the control. Numeric was significantly higher than the control ( p=.003) and pictorial (p=.028), but there was no difference between the pictorial group and the control ( p<.10). Although susceptibility was higher when incidence rates were present for both benign and serious conditions, rates were higher for benign conditions than the serious conditions (p<.001) suggesting that people are not escalating. These results also fall in line with the statistical results shown on the search result’s page. Previous escalation studies suggested this phenomenon (Aiken et al., 2012; Starcevic & Berle, 2013; White & Horvitz, 2009), but it has not been tested up until this point. It would be beneficial to replicate the study with a more diverse population to obtain more generalizable results; however, the findings from this study could be helpful in understanding how patients comprehend healthcare information and could conceivably provide direction for how health care professionals distribute information to their patients.}, number={1}, journal={Proceedings of the Human Factors and Ergonomics Society Annual Meeting}, publisher={SAGE Publications}, author={Zielinska, Olga A. and Mayhorn, Christopher B.}, year={2015}, month={Sep}, pages={537–537} } @inproceedings{mcdougald_mayhorn_2015, title={Persuasive technology: An investigation of efficacy using process tracing}, booktitle={Proceedings of the 19th World Congress of the International Ergonomics Association}, author={McDougald, B.R. and Mayhorn, C.B.}, year={2015} } @article{witschey_zielinska_welk_murphy-hill_mayhorn_zimmermann_2015, title={Quantifying Developers' Adoption of Security Tools}, DOI={10.1145/2786805.2786816}, abstractNote={Security tools could help developers find critical vulnerabilities, yet such tools remain underused.

A virtual reality–based methodology was used and a between‐subject design was considered. Thus, participants were given the tasks of finding three publicly accessible central points in a virtual hotel and confronted with a two forced‐choice task of local scenes in which environmental variables (i.e., corridor width and brightness) and signage varied systematically, in two experimental conditions (i.e., neutral and signage). For the signage condition, signs were inserted to explicitly point in the opposite direction than that implicitly suggested by the environmental affordances, creating situations with conflicting information. Results indicate that environmental variables were able to direct people indoors acting as environmental affordances. Users preferred to follow the wider and brighter paths.

This can contribute to increased safety on the farm, from engineering to human factors and ergonomics. Methods The current set of studies used two distinctly different research approaches to identify areas most linked to agricultural safety incidents. Focus groups including older farmers and an analysis of archived data produced descriptions of where, when, and how accidents occur, and what hazards contributed to these accidents. The database used was the Fatality Assessment and Control Evaluation (FACE) database of fatal farm-related accidents. This database contains a structured narrative account of each accident. Cases were coded to capture the demographics of the victim, the environmental conditions during the accident, the machinery involved, and other variables related to the accident. The average age of farmers involved in fatal accidents was over fifty years and many of them were using decades-old equipment when they died. These data are presented in terms of frequencies and a cluster analysis was performed to identify patterns of accident types. Focus group discussions identified the knowledge and attitudes of older farmers related to their work and equipment. Results In general, older farmers understood that they had slower reaction times than when they were younger; however, the prevailing attitude was that a task must be accomplished by any means necessary. This included working in poor visual conditions, past the point of fatigue, and using equipment for tasks other than for which it was designed. Last, older farmers were aware of numerous accidents related to their profession and expressed an acceptance of risk as well as the attitude that those who had accidents were not careful enough. Conclusion The findings from these studies can be used to motivate influential safety research. Older farmers stand to benefit greatly from applied work in this area once their general behavior patterns with farming technology are understood. The goal of the current studies was to link the information from farming accidents with the knowledge, attitudes, and behaviors of older farmers to direct the solving of safety problems through engineering, human factors, and industrial design.}, number={1}, journal={Gerontechnology}, publisher={International Society for Gerontechnology (ISG)}, author={McLaughlin, A.C. and Mayhorn, C.B.}, year={2011}, month={Jan}, pages={26–37} } @inbook{wogalter_laughery_mayhorn_2011, place={Boca Raton, FL}, title={Communication-Human Information Processing Stages in Consumer Product Warnings}, ISBN={9781420046243 9781420046250}, ISSN={2155-8604}, url={http://dx.doi.org/10.1201/b10949-5}, DOI={10.1201/b10949-5}, abstractNote={3.1 InLroducLion .......................................... ....... .......... ................................... .............................. 33 3.2 Issues Assoc iated with the Hierarchy ................ ....... ........................................................ ...... 34 3.3 Alternative Designs ................................. ....................... .......................... ...... ................... ..... 34 3.4 Factors Lhat Influence Safe ty Decisions .................................................................................. 35 3.5 Warning versus Alternative Design versus Guarding ................. ....... ........... ......................... 36 3.6 Final Comments .................................................................................... ....................... .... ....... 38 References .......................... ..................... ......... ............ ........ ........... .................. ..... ......... ................. 38}, booktitle={Human Factors and Ergonomics in Consumer Product Design}, publisher={CRC Press}, author={Wogalter, Michael and Laughery, Kenneth and Mayhorn, Christopher}, editor={Karwowski, Waldemar and Soares, Marcelo M. and Stanton, Neville A.Editors}, year={2011}, month={Jun}, pages={41–67} } @article{carpenter_mayhorn_2011, title={Effect of transfer with younger and older adults on control solution testing using two blood glucometers}, DOI={10.1037/e578902012-035}, journal={PsycEXTRA Dataset}, publisher={American Psychological Association (APA)}, author={Carpenter, Eric D. and Mayhorn, Christopher B.}, year={2011} } @article{carpenter_mayhorn_2011, title={Effect of transfer with younger and older adults on control solution testing using two blood glucometers}, volume={55}, ISSN={1541-9312}, url={http://dx.doi.org/10.1177/1071181311551035}, DOI={10.1177/1071181311551035}, abstractNote={As of 2005, 5.5% of the American population had some form of diabetes, with an increasing rate of diagnosis.

However, its impact on healthcare consumer safety is not well-understood. This effort sought to examine DTCA healthcare consumer effects and their public health and practical implications. During spring 2008, 2767 individuals were asked, through public intercept interviews, about pharmaceutical DTCA: recalled products, exposure frequency, exposure medium, and impact on a range of health-related behaviors and beliefs. Consumers report inundation with DTCA, with 8 of 10 respondents indicating exposure to messaging within the past 30 days. Television was the medium with the most noted impressions; direct mail, the least (although still >35%). Most impressions reported were for Viagra and Claritin. One of four participants reported cognitive or behavioral changes as a result of viewing DTCA: advertisements prompted people to believe they had an illness/condition, to seek more information, to schedule provider visits, and to ask providers about symptoms or medications during regular visits. Moreover, almost 1 in 5 reported an increased willingness to share their prescription medication with others if they saw it in DTCA, indicating that DTCA exposure may increase this risky behavior. DTCA are nearly ubiquitous yet consumers remained attuned to the message content. The effects of DTCA are complex and range from beneficial (e.g., information-seeking) to detrimental (e.g. medication-sharing). Interestingly, participants do not readily differentiate prescription versus over-the-counter DTCA. Increased attention to understanding DTCA appears worthwhile, perhaps targeting provider awareness of message effect, further regulation and modification of DTCA messaging, and enhancing DTCA media literacy as a component of health literacy. Human factors professionals have the right toolset to play an active role in these efforts. }, number={21}, journal={Proceedings of the Human Factors and Ergonomics Society Annual Meeting}, publisher={SAGE Publications}, author={Mayhorn, Christopher B. and Goldsworthy, Richard C.}, year={2010}, month={Sep}, pages={1885–1889} } @article{mayhorn_goldsworthy_2010, title={Messages and medical behaviors: DTCA's influence on healthcare consumer thinking and doing, and how we can help}, DOI={10.1037/e578822012-013}, journal={PsycEXTRA Dataset}, publisher={American Psychological Association (APA)}, author={Mayhorn, Christopher B. and Goldsworthy, Richard C.}, year={2010} } @article{kim_wogalter_mayhorn_2010, title={Older and Younger Drivers' Beliefs about Motor Vehicle Features to Benefit Their Safe Driving}, DOI={10.1037/e578632012-005}, journal={PsycEXTRA Dataset}, publisher={American Psychological Association (APA)}, author={Kim, Soyun and Wogalter, Michael S. and Mayhorn, Christopher B.}, year={2010} } @article{kim_wogalter_mayhorn_2010, title={Older and Younger Drivers' Beliefs about Motor Vehicle Features to Benefit Their Safe Driving}, volume={54}, ISSN={2169-5067 1071-1813}, url={http://dx.doi.org/10.1177/154193121005400205}, DOI={10.1177/154193121005400205}, abstractNote={ Because there are age-related perceptual, motor, and cognitive declines and because people are living longer, there has been increased concern about older drivers' ability to operate motor vehicles safely.

There have been hundreds of research-based articles written in various journals as well as several comprehensive books. This special issue of Human Factors and Ergonomics in Manufacturing & Service Industries (HFEMSI) concerns the topic of warnings. Although there have been special issues on warnings in several human factors/ ergonomics journals, this is the first for HFEMSI. Warnings are relevant in the sectors of manufacturing and service because hazards are embedded in most contexts today. For example, in manufacturing, there are dangers in the production side of product and equipment, as well as hazards involved in the actual use. There are diverse contexts in which warnings are used as a means to disseminate safety information for the purpose of reducing hazard-related harm to people and property. Examples include warning labels on products, signage in environments, and admonitions in operator’s manuals for industrial equipment. Co-occurring with the growing body of warning research has been the development of models to conceptualize the cognitive processing involved when people encounter effective warnings (e.g., Edworthy & Adams, 1996; Lehto & Miller, 1986; Rogers, Lamson, & Rousseau, 2000). A recent iteration of the communication-human information processing (C-HIP) model (see Wogalter, 2006) can be used to conceptualize much of the body of research on warnings.

Understanding our audiences—workers and consumers—is an especially important, often overlooked, aspect of risk and harm reduction efforts. In this article, particular attention is paid to audience analysis in hazard communication and warning messaging, with a focus on the potential role of latent class analysis (LCA). We provide an example of using LCA to analyze a hazardous behavior: prescription medicine sharing and borrowing. Four distinct groups of people—ranging from abstainers to at‐risk sharers—are identified and discussed. Building better warnings and risk communication techniques is essential to promoting occupational and consumer safety. Audience analysis is a vital component of these efforts. LCA appears to be a worthwhile addition to our analytical toolbox by allowing risk reduction and hazard‐mitigation efforts to tailor interventions to a diverse target audience. © 2010 Wiley Periodicals, Inc.}, number={6}, journal={HUMAN FACTORS AND ERGONOMICS IN MANUFACTURING & SERVICE INDUSTRIES}, publisher={Wiley}, author={Goldsworthy, Richard C. and Mayhorn, Christopher B. and Meade, Adam W.}, year={2010}, pages={484–499} } @article{mayhorn_goldsworthy_2009, title={Borrowing prescription medication: Implications for healthcare warnings and communications}, DOI={10.1037/e578542012-015}, journal={PsycEXTRA Dataset}, publisher={American Psychological Association (APA)}, author={Mayhorn, Christopher B. and Goldsworthy, Richard C.}, year={2009} } @inproceedings{mayhorn_goldsworthy_2009, title={Direct-to-consumer advertising: A one-sided health communication "experiment"?}, booktitle={137th American Public Health Association Annual Meeting and Exposition}, author={Mayhorn, C.B. and Goldsworthy, R.C.}, year={2009} } @inproceedings{mayhorn_goldsworthy_2009, title={Exploring the impact of prescription medication sharing}, booktitle={Proceedings of the 17th World Congress of the International Ergonomics Association}, author={Mayhorn, C.B. and Goldsworthy, R.C.}, year={2009} } @article{mayhorn_2009, title={Human factors/ergonomics: An international perspective}, volume={52}, number={10}, journal={HFES Bulletin}, author={Mayhorn, C.B.}, year={2009}, month={Oct} } @article{mayhorn_goldsworthy_2009, title={New and Improved: The Role of Text Augmentation and the Application of Response Interpretation Standards (Coding Schemes) in a Final Iteration of Birth Defects Warnings Development}, volume={85}, ISSN={["1542-0760"]}, DOI={10.1002/bdra.20601}, abstractNote={AbstractBACKGROUND:Several birth defects warning symbols identified as most successful in an earlier study (Mayhorn and Goldsworthy, 2007) were further modified and then evaluated within a nationally distributed field trial (n = 2773). The purpose for the current research was to determine whether symbol warning components could be improved further, whether the addition of text enhanced comprehension uniformly across symbols, and whether results varied by the application of different interpretation standards (coding schemes).METHOD:A total of 11 warning labels were examined: four new symbols plus the existing baseline symbol, each in versions with and without text, plus a text‐only condition. Participant interpretation accuracy and preferences were assessed during face‐to‐face interview sessions.RESULTS:For symbol‐only conditions, several candidate symbols outperformed the existing symbol, one substantially so. The effect of adding text to symbols varied significantly by symbol. Symbol plus text and text‐only conditions performed equivalently, generally exceeded symbol‐only conditions, and often surpassed the American National Standards Institute benchmark of 85% accurate interpretation.CONCLUSIONS:The research effort has identified a teratogen symbol and warning that outperforms the one currently in use. The effort has also identified important pragmatic and conceptual issues that should inform future work to improve medication labeling and other hazard communication.

We sought to document the frequency, circumstances, and consequences of prescription medication–sharing behaviors and to use a medication-sharing impact framework to organize the resulting data regarding medication-loaning and -borrowing practices. Methods. One-on-one interviews were conducted in 2006, and participants indicated (1) prescription medicine taken in the past year, (2) whether they had previously loaned or borrowed prescription medicine, (3) scenarios in which they would consider loaning or borrowing prescription medicine, and (4) the types of prescription medicines they had loaned or borrowed. Results. Of the 700 participants, 22.9% reported having loaned their medications to someone else and 26.9% reported having borrowed someone else’s prescription. An even greater proportion of participants reported situations in which medication sharing was acceptable to them. Conclusions. Sharing prescription medication places individuals at risk for diverse consequences, and further research regarding medication loaning and borrowing behaviors and their associated consequences is merited. }, number={6}, journal={AMERICAN JOURNAL OF PUBLIC HEALTH}, publisher={American Public Health Association}, author={Goldsworthy, Richard C. and Schwartz, Nancy C. and Mayhorn, Christopher B.}, year={2008}, month={Jun}, pages={1115–1121} } @article{kim_mayhorn_2008, title={Exploring students' prospective memory inside and outside the lab}, volume={121}, ISSN={["1939-8298"]}, DOI={10.2307/20445459}, abstractNote={Abstract This study compared activity-based intentions with event- and time-based intentions.

To evaluate output monitoring, event-based cues were repeated and participants were asked to press a different key if they could remember that an earlier response was made to a particular cue. Younger adults forgot fewer of their successful responses, but displayed a distinct bias to claim that they had responded earlier when actually they had forgotten to respond. By contrast, older adults displayed this bias much less frequently. Elaborated responding to cues had the effect of improving the performance of younger, but not older adults.

In the current experiment, 56 relatively knowledgeable computer users completed a decision-making task that included 24 scenarios which varied in terms of decision domain (computer vs. non-computer), risk (high vs. low), and gain-to-loss ratio (high gains/low losses, equal gains/losses, low gains/high losses). Results indicated that there was no difference between computer and non-computer decisions when risk and gain-to-loss ratio were held constant. However, these decision factors did interact to differentially influence decisions within each of these domains. Perception of risk greatly impacted computer decisions whereas the gain-to-loss ratio seemed to have a larger influence on the non-computer decisions.

A total of 330 individuals participated; 72% owned a cellular phone. The results indicate that nonusers of cellular phones believed more strongly than users that cellular phone use while driving negatively affects driving performance and that talking on the cellular phone could potentially cause an accident, and they also had a greater preference for new laws limiting such acts. Cellular phone users, more than nonusers, preferred no laws limiting cellular phone use and believed more strongly that other people driving while using a cellular phone were more dangerous than themselves doing the same.

Another source of error resulted from participants confusing the orange with the yellow threat condition (12.1%).Together. these twO categories of confusion account for more than 90% of the color-sorting errors. The word-sorting task revealed somewhat better results: only 33.3% of the sample deviated from the correct order.

Participants were the most accurate when asked to order the descriptive phrases. compared with the other sorting tasks. In the phrase-sorting task. 26.3% deviated from the correct order. Participants most frequendy confused "Significant risk of terrorist attacks" with "High risk of terrorist attacks" (26.7%) and less frequently confused "Severe risk of terrorist attacks" with "High risk of terrorist attacks" (13.3%).Together. these categories of error accounted for 40% of the errors during phrase sorting. The error-laden results of the three sorting tasks provide converging evidence that HSASmay not be an effectivehazard communication tool. These results are not surprising when considered In the context of previous work within the human factors/ergonomics warnings literature (laughery. Wogalter. & Young,I994;Wogalter,Young,& Laughery,200 I). For instance, the results of the color-sorting task are consistent with previous research: Although the color red consistently connotes the presence of a hazard, orange and yellow are not readily differentiated on the hazard continuum (Chapanls, 1994).Colors such as red and yellow suggest greater levelsof hazard than other common colors, such as green and blue, but research indicates that people do not perceive blue to be mori! hazardous than green (Braun & Silver. 1995;Rashid & Wogalter, 1997).Thus, participants' poor performance on the color-sorting task was predictable. Had human factors/ergonomics professionals been consulted on the design of HSAS.the misunderstandings associated with color coding of threat levels might have been avoided, resulting In a more effective hazard communication tool. Similarconfusions in the wordand phrase-sorting tasks might also have been avoided in light of extensive research demonstrating that people frequently have difficultydistinguishing one signalword from another, such as "danger," "warning:' and "caution" (Braun.Kline,& Silver,1995;leonard. I999).The designers of HSASmight have avoided the use of this attribute entirely. At the very least, HSASshould have been tested prior to deployment to determine whether the public could distinguish among the five threat levels.Had this testing occurred and the findings refleCted the confusion revealed in the present results, alternative attributes such as numbers (I.e.. 1-5) or percentages (e.g.,80%) might have been explored as a means to disambiguate the threat levels.}, number={4}, journal={Ergonomics in Design: The Quarterly of Human Factors Applications}, publisher={SAGE Publications}, author={Mayhorn, Christopher B. and Wogalter, Michael S. and Bell, Jennifer L. and Shaver, Eric F.}, year={2004}, month={Oct}, pages={12–14} } @article{leynes_mayhorn_2003, title={A reply to R.

Framing decision options as either gains or losses is a common method of altering decision-making behavior. In the experiment reported here, benchmark decision-making data collected in the 1970s by Tversky and Kahneman (1981, 1988) were compared with data collected from current samples of young and older adults to determine whether behavior was consistent across time. Although differences did emerge between the benchmark and the present samples, the effect of framing on decision behavior was relatively stable. The present findings suggest that adults of all ages are susceptible to framing effects. Results also indicated that apparent age differences might be better explained by an analysis of cohort and time-of-testing effects. Actual or potential applications of this research include an understanding of how framing might influence the decision-making behavior of people of all ages in a number of applied contexts, such as product warning interactions and medical decision scenarios. }, number={4}, journal={HUMAN FACTORS}, author={Mayhorn, CB and Fisk, AD and Whittle, JD}, year={2002}, pages={515–521} } @article{nichols_mayhorn_rogers_fisk_2002, title={Ecology of product hazards in the older adult home: Hazard awareness and warning perception}, volume={2}, DOI={10.4017/gt.2002.02.01.057.00}, number={1}, journal={Gerontechnology}, publisher={International Society for Gerontechnology (ISG)}, author={Nichols, T.A. and Mayhorn, C.B. and Rogers, W. and Fisk, A.D.}, year={2002}, month={Jan} } @article{nichols_mayhorn_whittle_hancock_rogers_fisk_2002, title={Hazardous Products in the Older Adult Home}, volume={46}, ISSN={2169-5067 1071-1813}, url={http://dx.doi.org/10.1177/154193120204601908}, DOI={10.1177/154193120204601908}, abstractNote={ Older adults appear to be particularly susceptible to hazards in the home environment.
