Assessing Mental Models of Emergencies Through Two Knowledge Elicitation Tasks

Objective: The goals of this study were to assess the risk identification aspect of mental models using standard elicitation methods and how university campus alerts were related to these mental models. Background: People fail to follow protective action recommendations in emergency warnings. Past research has yet to examine cognitive processes that influence emergency decision-making. Method: Study 1 examined 2 years of emergency alerts distributed by a large southeastern university. In Study 2, participants listed emergencies in a thought-listing task. Study 3 measured participants’ time to decide if a situation was an emergency. Results: The university distributed the most alerts about an armed person, theft, and fire. In Study 2, participants most frequently listed fire, car accident, heart attack, and theft. In Study 3, participants quickly decided a bomb, murder, fire, tornado, and rape were emergencies. They most slowly decided that a suspicious package and identify theft were emergencies. Conclusion: Recent interaction with warnings was only somewhat related to participants’ mental models of emergencies. Risk identification precedes decision-making and applying protective actions. Examining these characteristics of people’s mental representations of emergencies is fundamental to further understand why some emergency warnings go ignored. Application: Someone must believe a situation is serious to categorize it as an emergency before taking the protective action recommendations in an emergency warning. Present-day research must continue to examine the problem of people ignoring warning communication, as there are important cognitive factors that have not yet been explored until the present research.

Problematic Texting Behaviors Individual Differences in Personality

Problematic texting behaviors consist of well-understood behaviors (such as texting while driving) and behaviors that have not been thoroughly researched in the past. A study was performed to examine several physically and socially problematic texting habits with respect to individual differences in personality and sensation-seeking behavior. Participants completed several self-report surveys gauging texting habits, personality, and sensation seeking. General findings indicated that extraversion and neuroticism were positively related to some socially problematic texting behaviors, but unexpectedly, extraversion was related to non-social aspects of texting, such as texting while driving. The disinhibition subscale was most strongly related to almost all of the problematic texting behaviors that we assessed, most notably for texting and driving. Based on these findings, an example of using individual differences to improve analyses of problematic texting behavior is provided. Additional results and implications for human factors are further discussed.

Texting as a Multidimensional Behavior: Individual Differences and Measurement of Texting Behaviors.

Two studies were conducted to develop and confirm a generalized measure of texting behavior, the Texting Behaviors Index, using exploratory and confirmatory factor analysis on samples of undergraduate students. A solution containing 6 factors for texting behaviors was supported, which were named social connection, escapist, distracted, audacious, nurtured communication, and driving. The characteristics of these factors were explored using individual differences in personality and sensation-seeking behavior, where extraversion and disinhibition were consistent significant predictors for many types of texting. Additionally, a measure of depressive symptoms was predictive of some types of problematic texting. In general, our results support that texting is not a unidimensional social behavior, but a multidimensional behavior composed of social and nonsocial facets, including problematic behavior. The usefulness of this scale, particularly with respect to problematic texting behaviors, and future applications for empirical, survey, meta-analytic, and health research are discussed.

Toward a User-Centered Approach for Emergency Warning Distribution:

There are many known problems with inappropriate response to emergency warnings. Recommended actions are not always properly followed, and sometimes emergency warnings are not taken seriously. A variety of psychological individual differences can influence the perception of emergency warnings. At present, warning distributors do not consider how these factors affect emergency warning response. We recommend that emergency warning distribution systems be developed that account for these differences to improve response. To this end, we propose four guidelines supported by psychological research and inspired by currently available technologies. These guidelines frame a user-centered approach to more appropriately tailor warning messages for each recipient.

Individual Differences in Middle School and College Students’ Texting

The present study surveyed a sample of middle school students on their technology habits, with a primary focus on texting behaviors. A secondary sample of college students was surveyed as a comparison group to examine individual differences in texting behaviors. Results indicate that college students text more frequently than middle schoolers; however, college students’ texting behaviors decrease in frequency as they get older, whereas middle schoolers’ texting behaviors increase in frequency. Females also generally reported texting more frequently than males. Extraversion was found to be predictive of texting in the middle school sample, but both Extraversion and Neuroticism were found to be predictive of texting in the college sample. Results are discussed in the context of previous research and with respect to human factors and developmental psychology, such that the study of technology use could offer insight into the social development of adolescents and young adults.

Perceptions of Mobile Instant Messaging Apps Are Comparable to Texting for Young Adults in the United States

In recent years, text messaging (“texting”) has become the dominant method of communication for young adults. This prevalence of texting has led to research exploring the beneficial and detrimental behaviors associated with texting, indicating wide-ranging social and human factors implications. As texting continues to take precedence over other forms of communication and research begins to address texting behaviors, the question arises about whether people use other mobile instant messaging applications (“IM apps”) similarly. The current study expands on the research of texting behaviors by asking how similarly young adults view apps (e.g., WhatsApp, Facebook Messenger, etc.) to texting. Results indicated that young adults in the United States use texting more frequently than text-based apps, but that these apps are viewed similarly to texting. The implication is that research addressing texting behaviors may apply to other forms of text-based communication; however, texting remains the most prominent mode of communication, justifying its own continued examination.

Unsafe Texting and Socially Problematic Texting: Need for Cognition as an Underlying Predictor

As texting becomes the dominant medium for communication, problematic and unsafe texting habits arise. Understanding who is more likely to engage in problematic texting can give insight into the underlying traits driving these behaviors. The current exploratory study investigated the extent to which texting habits were correlated with an individual difference measure, the Need for Cognition scale. Results indicated endorsement of certain texting behaviors is inversely related to an individual’s need for cognition, or the extent to which a person enjoys and engages in thinking. In particular, texting behaviors related to safety (e.g., texting while walking), avoidance texting (e.g., texting while in a new place), negative behaviors (e.g., texting to insult or gossip), and health (e.g., waking up to respond to texts) were correlated negatively with stronger need for cognition. These and other texting behaviors have human factors implications of health, safety, and interpersonal relations.

Predictors of Views about Punishing Animal Abuse

ABSTRACT The current study used scenarios of animal cruelty based on actual events to explore what factors predict perceptions of punishments for animal cruelty. Five hundred thirty-eight university undergraduates participated in the study. Participants read scenarios based on an actual event of animal cruelty and with information on statutes addressing animal cruelty in their state. Participants were then asked to give ratings for punishment of the animal cruelty perpetrator. A canonical correlation analysis was used to test the multivariate shared relationship between the set of eight predictor variables and the criterion variable set of 15 punishment ratings. The response distributions were highly skewed for seven of the 15 criterion variables, highlighting the strong sentiments participants expressed against animal cruelty. The canonical correlation analysis identified significant criterion variables that were predicted by two of the empirically manipulated predictor variables (Perpetrator Age and Location of Crime) along with one subject variable (Participant Femininity). This set of predictor variables correlated with the criterion variable set that included Allowed with Children and Amount of Fine for Suffering. There was a main effect for Perpetrator Age, such that the degree to which participants thought a perpetrator of animal cruelty should be allowed alone with children depends on the age of the perpetrator. Mean responses were stronger for scenarios with perpetrators aged 28 than with perpetrators aged 12. The average response to Amount of Fine for Suffering was larger when the animal cruelty happened at a pet kennel than if the crime occurred at an animal shelter. Implications for these significant predictor and criterion variables are discussed in the context of interdisciplinary theory and practical implications for public policy.

Change in Memory of Emergency Warnings: The Case of An Averted Campus Shooting

The goal of this research was to examine individuals’ proximity, gender, and memories about a specific situation in which emergency alerts were distributed. Students, faculty, and alumni were surveyed online one week after an averted campus shooting and again nine months later. Overall, this research suggests that closer living proximity to campus positively influences subscription to the emergency alert system and that women are more interested in safety than men. Data suggest that participants’ memory of their emotional reaction to the event and their memory of perceiving the alerts as serious warnings stayed approximately the same. Responses immediately after the crisis indicated that people were significantly more confident in their memory and remember feeling more worry over not receiving a warning than did the responses nine months later. The uniqueness of the situation may have influenced the lack of memory inaccuracies, due to the reduced negativity and affect towards the situation.

Understanding emergency response: lessons learned from the helping literature

The purpose of this paper is to demonstrate the need for collaboration between two areas of research: classical psychological helping behaviours and emergency warnings. A large-scale disaster (i.e., the Chicago Heat Wave) is used throughout the paper as an example in which knowledge of the helping behaviour literature could have assisted emergency responders. The emergency warning literature is reviewed within the context of people heeding the warnings and deciding to share the information with others. Developments in the helping literature are reviewed, along with a final summary of key lessons from this area of experimental research that can help answer questions for future emergency responders. With a better understanding of experimental findings in the area of prosocial behaviours, emergency managers may be better able to assist their communities. Likewise, a greater collaboration between these two fields may lead to more research with the intent of improving emergency response.
