▼ The nursing environment is replete with event-based and time-based prospective memory (PM) tasks (i.e. high prospective load). However, the effects of time-based prospective load, prospective load in naturalistic settings, and prospective load with unique retrospective components for each PM task remains unknown. To address this gap, the current study used a mockup patient room setting to examine the effects of PM type (event-based or time based) and prospective load (1 vs. 4 tasks) with unique prospective and retrospective components) on ongoing task and PM task performance. Registered nurses completed an ongoing documentation task while also remembering to perform 1 or 4 PM nursing tasks at a certain time (time-based) or certain patient name (event-based). Results indicated that having an event-based intention decreased performance on the prospective component of the PM task and slowed performance on the ongoing task. Having a time-based intention in the one load condition positively affected timeliness of performing the PM task and number of records completed. Performance on the retrospective components of the PM task was equal across groups, but post retrospective recall of tasks was worse in the high prospective load conditions.

▼ In minimally invasive surgery (MIS), the ability to accurately interpret haptic information and apply appropriate force magnitudes onto soft tissue is critical for minimizing bodily trauma. Force perception in MIS is a dynamic process in which the surgeon's administration of force onto tissue results in useful perceptual information which guides further haptic interaction and it is hypothesized that the compliant nature of soft tissue during force application provides biomechanical information denoting tissue failure. Specifically, the perceptual relationship between applied force and material deformation rate specifies the distance remaining until structural capacity will fail, or indicates Distance-to-Break (DTB). Two experiments explored the higher-order relationship of DTB in MIS using novice and surgeon observers. Findings revealed that observers could reliably perceive DTB in simulated biological tissues, and that surgeons performed better than novices. Further, through calibration feedback training, sensitivity to DTB can be improved. Implications for optimizing training in MIS are discussed.

▼ This dissertation investigated the relationship between the spatial perception abilities of operators and robot operation under direct-line-of-sight and teleoperation viewing conditions. This study was an effort to determine if spatial ability testing may be a useful tool in the selection of human-robot interaction (HRI) operators. Participants completed eight cognitive ability measures and operated one of four types of robots under tasks of low and high difficulty. Performance for each participant was tested during both direct-line-of-sight and teleoperation. These results provide additional evidence that spatial perception abilities are reliable predictors of direct-line-of-sight and teleoperation performance. Participants in this study with higher spatial abilities performed faster, with fewer errors, and less variability. In addition, participants with higher spatial abilities were more successful in the accumulation of points. Applications of these findings are discussed in terms of teleoperator selection tools and HRI training and design recommendations with a human-centered design approach.

▼ The picture superiority effect (i.e. better memory for pictures than words) is well established in retrospective memory, but the examination of the picture superiority effect in prospective memory has been underrepresented in the literature. Understanding if pictures lead to better prospective memory than words has the theoretical benefit of increasing our understanding of what particular factors lead to spontaneous retrieval and the practical benefit of informing the design of memory aids. Additionally, I examine if there are differences in ongoing task and prospective memory task performance between age groups (old and young) and under different loads of attention (non-divided and divided). I hypothesized that pictures are more distinct than words, and will therefore promote spontaneous retrieval, which will be exhibited by high and stable performance in the picture (not word) conditions across both divided and non-divided attention tasks and equivalent prospective memory performance by younger and older adults in only the picture, not word conditions. Results demonstrated that a picture superiority effect does exist for prospective memory tasks. Participants viewing all picture stimuli not only remembered to perform the PM task more often than participants who viewed all word stimuli, they also performed the ongoing categorization task faster. Although my hypotheses were not fully supported, there is evidence for picture stimuli leading to spontaneous retrieval more than word stimuli. An applied example of how pictures can help alleviate memory demands is provided through a first-hand account of a newly diagnosed Type 1 diabetic's daily task of insulin administration.

▼ Recent research shows that such Information and Communication Technologies (ICTs) as instant messengers can cause workplace interruptions, which lead to stress for employees and substantial productivity losses for U.S. organizations. Since the introduction of ICTs, workplace interruptions have evolved in both frequency and nature from irregular phone calls to a continuous stream of e-mail notifications and other electronic interruptions, mediated through a large number of technological devices that constantly beep and buzz. This trend of an increasing frequency of workplace interruptions closely relates to another workplace trend: the graying of the workforce, implying that the U.S. workforce is aging at an increased rate. Since older people are particularly vulnerable to interruptions, the interdependencies inherent in these two workplace trends need to be better understood. Accordingly, this dissertation aims to understand whether, how, and why technology-mediated (T-M) interruptions impact stress and task performance differently for older compared to younger adults. To examine these questions, this research applies two complementary theoretical frames that explain interruptions' influence on older and younger adults' cognition. First, the Person-Environment Fit perspective suggests that T-M interruptions may lessen the fit between the mental resources available for performing a task and those required, thereby inducing workplace stress and, in turn, reducing individual task performance. Second, the Inhibitory Deficit Theory of Cognitive Aging holds that older peoples' ability to actively disregard distracting stimuli is impaired. Thus, more T-M interruptions may 'steal' resources from the processing of task-related content in older adults. In combining these theories with user characteristics and technology features, this research develops an integrative model of ICTs, aging, stress, and task performance. We propose that older people are more distracted by T-M interruptions than younger, thereby experiencing greater mental workload and, in turn, more stress and lower performance. We test the model through a laboratory experiment that integrates the manipulation of ICT features with objective measures of stress and task performance, unlike the subjective measures commonly used. Experimental manipulations include the frequency with which interruptions appear as well as such interruption design characteristics as color codes. Outcome measures include actual performance in terms of the number of task elements solved, as well as the change in stress hormones found in saliva, a state-of-the art physiological measure of stress. In developing and testing the model, we help to clarify the role of age in technostress. This research also sheds more light on the mental processes that connect ICTs to stress and performance, and it has begun to open the black box of the ICT features linked to these outcomes. For managers, we provide guidance on assisting older employees in realizing their…

▼ Complex decision-making may be aided by forms of automation known as decision-support systems (DSS). However, no DSS is completely reliable and so it is imperative that users know when they should and should not trust it (calibration of trust). Previous research has shown that providing users with information about the DSS's confidence in its own advice ('system confidence') can help improve the calibration of user's trust of automation and actual system reliability on a trial by trial basis. The current study examined how the nature of the presentation of system confidence information affected user's trust calibration. The first study examined the attentional demand of each display, while the second study examined their effect on trust and performance on a decision making task. The results of this study indicate that there was no effect of system confidence display type on subjective or objective trust. The lack of differences in performance or trust between the control condition (no system confidence display) and other displays raises doubts about whether users were utilizing the system confidence information or using reliability information. The type of decision task may be crucial in determining whether to provide system confidence and these results suggest that it should be tested prior to implementation against a control group, unlike previous studies. The results of these studies have implications in the design of DSS, especially given the difficulty of providing accurate system confidence information to users. The time and resources that would be required to provide such a display may not be beneficial if it has no effect on user trust or decision performance

▼ A consistent interface is thought to be beneficial because it allows users to draw on previous training and experience when operating a new interface. Design guidelines like the eight golden rules of interface design argue that a highly consistent interface improves system usability (Shneiderman, 1987). However, interface consistency is not monolithic; instead it is a complex, multidimensional construct. I refer to the two dimensions of interface consistency as perceptual consistency (the appearance) and conceptual consistency (the functionality) of an interface. Perceptual consistency considers aspects like interface layout and orientation; conceptual consistency considers how the system operates or responds. I sought to understand how combinations of these dimensions might affect performance and user perceptions of a system. For example, what if a system looks the same but operates differently? Results indicate that both an inconsistent appearance and an inconsistent functionality can hurt performance. Forcing consistency, however, may not be beneficial either. When there was a mismatch between dimensions (i.e., one was consistent and the other inconsistent) performance was worse than that of an entirely inconsistent version. Specifically, participants in the conceptual inconsistency and perceptual consistency condition (operates differently but looks the same) performed worse and reported higher workloads. Designers should encourage interface consistency by making systems that function similarly also share a similar appearance; however, when the systems are functionally disparate (i.e., they do different things) designers should take care to avoid implying similarities where they do not exist.

▼ Although interface consistency is theorized to increase performance and user satisfaction, previous research has found mixed and often non-significant results. The source of this discrepancy may be due to varying levels of task difficulty employed in these past studies. This study attempted to control the task difficulty using cognitive load theory. Interface consistency was manipulated along with intrinsic cognitive load and extraneous cognitive load. Interface consistency was manipulated along three dimensions: physical, communicational and conceptual. Intrinsic cognitive load was manipulated by asking participants finance (high load) questions and travel (low load) questions. Unnecessary and irrelevant extra hyperlinks were used to manipulate extraneous cognitive load. These hyperlinks were either present (high load) or absent (low load) in the websites. Forty eight participants searched for answers to 24 questions across four separate websites. Results indicated interactions between consistency and the two types of cognitive load. These interactions suggest that the effects of consistency are dependent upon the difficulty of the task. Specifically, consistency may be especially important for difficult tasks with high cognitive load.

▼ Older adults are faced with complex decision tasks that impose high working memory demands. A representative task is choosing a prescription drug plan from a multitude of options that must be evaluated along many factors. The combined effect of the quantity of complex information, and reduced working memory capacity puts older adults at a disadvantage. However, research with younger adults suggests that the working memory burden of decision tasks can be reduced using well-designed, graphical decision aids (i.e., environmental supports). The current study examined the use of environmental supports to support complex decision-making for older adults. Two experiments were conducted; experiment 1 assessed two information visualizations (color and size) on their ability to minimize the working memory demands of the task. Results from experiment 1 suggest that the color information visualization does in fact minimize working memory demand by replacing cognitive comparisons with perceptual comparisons. The second experiment validated the efficacy of the color information visualization in an older adult group. Findings suggest that the use of color to visualize information can successfully ameliorate working memory demand for direct comparisons, but not for complex integration tasks. Finally, the results suggest that information visualizations that rely on perceptual abilities rather than cognitive abilities may help improve older adults' decision making accuracy.

▼ Organizational recruitment websites have become an important tool for both recruiters and job seekers. The structural characteristics of such websites (e.g., aesthetics, usability) have received some attention but less research has examined the content of these websites. A weblog (or blog), specifically a leader or CEO blog, is one novel way that organizations can impact recruitment through their website. Although research is limited, anecdotal evidence suggests that blogs may be a powerful recruiting tool. In line with research that suggests followers prefer leaders who are similar to themselves (e.g., Keller, 1999), the effectiveness of leader blog messages for recruitment purposes may be a function of how well the content and/or style match the characteristics of the job seekers. The current study examined job applicant personality characteristics as well as implicit leadership theories (ILTs; Offerman, Kennedy, & Wirtz, 1994) as predictors of leader preference, and subsequent attraction to the organization, using an organizational recruitment website with leader information presented in a weblog. Perceptions of the leader were found to be more favorable when the content of the blog was consistent with participants' ILT, such that increases in ratings of the corresponding ILT component were associated with increased preference for the leader. The current study provides support for the position that ILTs are important for understanding ratings of leader preference, and furthermore, that these effects can be found simply by reading a blog on a website.

▼ Ambient displays are used to provide information to users in a non-distracting manner. The purpose of this research was to examine the efficacy of facial expressions as a method of conveying information to users in an unobtrusive way. Facial expression recognition requires very little if any conscious attention from the user, which makes it an excellent candidate for the ambient presentation of information. Specifically, the current study quantified the amount of attention required to decode and recognize various facial expressions. The current study assessed the attention-demanding characteristics of facial expressions using the dual-task experiment paradigm. Results from the experiment suggest that Chernoff facial expressions are decoded with the most accuracy when happy facial expressions are used. There was also an age-effect on decoding accuracy; indicating younger adults had higher facial expression decoding performance compared to older adults. The observed decoding advantages for happy facial expressions and younger adults in the single-task were maintained in the dual-task. The dual-task paradigm revealed that the decoding of Chernoff facial expressions required more attention (i.e., longer response times and more face misses) than hypothesized, and did not evoke attention-free decoding. Chernoff facial expressions do not appear to be good ambient displays due to their attention-demanding nature.

▼ Reputation mechanisms and credibility are methods of adding additional information to forum posts, and are becoming more commonplace in online health forums. These systems provide users of forums additional information which can be used to evaluate the trustworthiness of the information being disseminated in community-run websites. The goal of the following studies is twofold. First, it is necessary to identify which elements of reputation systems and credibility participants use to make assessments of the trustworthiness, perceived credibility, and perceived accuracy of answers to health-related questions on a simulated web forum. Once the reputation mechanisms and credibility systems have been identified, the second study explored how high and low overall reputation affects decisions in a non-compensatory decision-making task. This study demonstrated a preference for a non-dominating alternative when it is associated with high reputation, and an overwhelming preference for a dominating alternative when associated with a high reputation. This study also showed that participants expressed higher levels of perceived credibility, trust, confidence, and accuracy of answers when making a decision based on reputation rather than utility.

▼ Traditional artifacts such as whiteboards serve as key tools in helping healthcare professionals keep track of frequently changing information and managing their work schedule. The simplicity of these tools has made them easy to adopt into the work culture and since these artifacts are not usually electronic, they need no external technical support or maintenance. However, these artifacts present unique challenges to their users, the primary one being lack of mobility offered. The whiteboards are usually stationary and the users will have to assemble near them to update or gather information. In a hospital, this adds significant overhead to the workflow efficiency since users will have to spend time walking from their changing locations to the whiteboards. In addition, the fact that these artifacts are not electronic means that they cannot be connected to the information technology (IT) system, meaning the information present on them are not updated in real-time. In this research, such challenges faced by certified and registered nurse anesthetists (CRNA) board runners of a large regional hospital in the south eastern United States were studied. To help address the challenges faced by the board runners in their task execution, a new web app designed for the Google Nexus 7 tablet was introduced as a potential replacement for the whiteboard. Ten board runners participated in this study to evaluate the new web app in comparison with the whiteboard in a simulated work environment. The participants were given 10 different tasks to perform with both the web app and the whiteboard. Measures such as task performance (time and errors), situational awareness (SA), needs ratings, system usability and perceived workload were collected and analyzed. Once the web app and the whiteboard were evaluated, a preference ranking for the type of device was also collected from all the participants. Time taken for overall task execution was longer for the whiteboard and the errors committed did not differ significantly among the two devices. SA was found to be similar across the devices and there were no significant differences. All 6 primary needs collected and the overall system usability were rated significantly higher for the web app. The workload indices of mental demand, physical demand, temporal demand, effort and frustration had significantly higher ratings for the whiteboard and the performance was rated significantly higher for the web app. All of the 10 participants preferred the web app over the whiteboard.

▼ The present study examined the potential relationship between specific characteristics of organizational recruitment web sites and applicant attraction to the organization. Cober, Brown, Keeping, and Levy (2004) proposed a conceptual model that suggests web site aesthetics influence the applicant's attitude toward the web site which in turn influences applicant attraction. The current study provides a partial test of this model by examining web site aesthetics, prior attitudes toward the organization, initial affective reactions to the web site, perceptions of web site usability and post-viewing attitudes toward the site and the organization. Participants (N = 159) included undergraduate students using the Department of Psychology's Subject Pool at a medium-sized southeastern
university. Data was analyzed using multi-level modeling. Results provide support that aesthetic characteristics influence participants initial affective reactions to the site. Also, participant's initial affective reactions influenced perceptions of usability, post-viewing attitude toward the web site, and attraction to the organization. Perceptions of usability also influenced attraction toward the organization and also partially mediated the relation between initial affective reactions and post-viewing attitude toward the site. Finally, post-viewing attitude toward the site partially mediated the relation between initial affective reactions and attraction to the organization as well as the relation between perceptions of usability and attraction to the organization.

▼ This dissertation focuses on the negative and positive outcomes of information and communication technology (ICT) in facilitating and reducing stress. The goals of this dissertation are twofold: 1) to deepen our understanding of how ICT-enabled interruptions influence individuals' episodic stress and 2) to examine whether ICTs may also be used to diminish stress evoked by ICT-enabled interruptions. Originating from psychology, the demands control model (Karasek, 1979) is used as an overarching theoretical lens to explain this technology-based duality, where technology serves as both a problem causing and a solution alleviating stress. The demands control model suggests that stressors have their greatest impact when control is low and demand stressors are high. This dissertation examined three characteristics of demands: the quantity of the ICT-enabled interruptions (quantitative demand), the variability of the ICT-enabled interruptions (demand variability), and the profile of the message (confounding or cooperating). To understand how to mitigate demands' outcomes, we examined three moderators of the demand stressor/strain relationship: ICT-enabled timing control, ICT-enabled method control, and resource control. Applying these factors within the demands control model, we argued that control factors mitigate the effects of high demands on both stress and strain. We tested our model using experimental design by administering two laboratory experiments. In doing so, we adopted a multi-method approach that uncovered how the body psychologically and physiologically reacts to ICT-based stressors. To examine physiological outcomes, we used two advanced tools that non-invasively captured indicators of strain: 1) salivettes captured cortisol and alpha-amylase found in saliva and 2) blood pressure recorders captured blood pressure and pulse rate. Then, we validated Likert-type scales to supplement objective indicators of stress. Our results indicated that strain was apparent when stress results from ICT-enabled stressors. In Experiment 1, we found that ICT-enabled interruption characteristics associated with demands served as stressors and led to perceptual stress (formed of perceptual overload, conflict, and ambiguity). We then found that ICT-enabled timing control negatively moderated the relationships between stressors and stress. Finally, our analysis revealed that perceptual overload positively led to strain, perceptual ambiguity partially led to strain, and perceptual conflict did not lead to strain. In Experiment 2, we found that coping behaviors negatively moderated the relationships between stressors, stress, and strain. Specifically, we found support for overall coping when it came to objective strain; however, we found no support that coping was a moderator with perceptual strain. In terms of specific coping behaviors, we found support that resource control minimized objective strain, while ICT-enabled method control minimized perceived and objective strain. We…

▼ Situation awareness (SA) is a measure of an individual's knowledge and understanding of the current and expected future states of a situation. While there are numerous options for SA measurement, none are currently suitable in dynamic, uncontrolled environments. Direct measures of SA are the most common, but require a large amount of researcher control as well as the ability to stop operators during a task in order to ask questions about their levels of SA. The current research explored the relationship between direct measures of SA and eye tracking measures as a first step in the development of an unobtrusive SA measure to be used in less controllable, dynamic environments. Two studies compared participant eye movements and SA in driving and air traffic control scenarios. Both studies showed that the more individuals fixated on an important, task-relevant event, the higher their SA for that event. The studies also provide evidence that the way operators allocate attention (i.e., distributed widely or narrowly) affects their SA as well as their task performance. In addition, study 2 results showed positive correlations between SA and task performance. The results indicate that eye tracking may be a viable option for measuring SA in environments not conducive to current direct SA measurement techniques. Future research should continue to explore which eye movement variables best predict participant SA, as well as to investigate the relationship between attention allocation and SA.

▼ The effect of sleep deprivation on cognitive task performance is becoming more important in today's society. Because of this, how total and partial sleep deprivation affect performance in the workplace needs to be better understood to increase awareness of how employees are able to perform. In addition, employers need to know if employees are able to accurately judge how sleep deprivation is affecting their own performance. The purpose of the current study was to compare the effects of total and partial sleep deprivation on actual and self-assessed performance on a logical reasoning task. Two studies, one under total sleep deprivation and one under partial sleep deprivation, were conducted. Each study examined participant performance on a logical reasoning task. Upon completion of the task, participants indicated how many questions they thought they answered correctly and how confident they were in that assessment. The results of this study suggest that while total sleep deprivation negatively affected performance on a logical reasoning task, partial sleep deprivation had no effect. Employers should be aware that employees who have experienced total sleep deprivation will be unable to maintain logical reasoning performance. When asked to estimate their own performance, participants consistently gave values that were higher than the actual values. Participants also remained very confident in their self-assessed performance estimations. In other words, if an employer asks employees to rate their performance, they will do so with a great level of confidence, even though their self-assessed performance values are likely to be higher than their actual performance values.
