Loneliness among older adults is a problem with severe consequences to individual health, quality of life, cognitive capacity, and life-expectancy. Although approaches towards improving the quality and quantity of social relationships are the prevailing model of therapy, older adults may not always be able to form these relationships due to either personality factors, decreased mobility, or isolation.

Show moreLoneliness among older adults is a problem with severe consequences to individual health, quality of life, cognitive capacity, and life-expectancy. Although approaches towards improving the quality and quantity of social relationships are the prevailing model of therapy, older adults may not always be able to form these relationships due to either personality factors, decreased mobility, or isolation. Intelligent personal assistants (IPAs), virtual agents, and social robotics offer an opportunity for the development of technology that could potentially serve as social companions to older adults. The present study explored whether an IPA could potentially be used as a social companion to older adults feeling lonely. Additionally, the research explored whether the device has the potential to generate social presence among both young and older adults. Results indicate that while the devices do show some social presence, participants rate the device low on some components of social presence, such as emotional contagion. This adversely affects the possibility of a social relationship between an older adult and the device. Analysis reveals ways to improve social presence in these devices.

The purpose of this study was to investigate how conservatism affects a person's perception of everyday details. It is hypothesized that there will be a positive correlation between the participants' conservative ratings and the amount of details from the readings they recall that are also conservative. This will also mean that there will be a negative correlation between the participants scoring higher on the conservatism scale and the amount of liberal details they recall. A similar pattern...
Show moreThe purpose of this study was to investigate how conservatism affects a person's perception of everyday details. It is hypothesized that there will be a positive correlation between the participants' conservative ratings and the amount of details from the readings they recall that are also conservative. This will also mean that there will be a negative correlation between the participants scoring higher on the conservatism scale and the amount of liberal details they recall. A similar pattern is expected to be discovered pertaining to participants that identify as more liberal. How is this measured? The participants will be asked to rate the their political views on a scale of 1-6, 1 being extremely liberal, and 6 being extremely conservative. A transcript of a political debate will contain views that are both conservative and liberal. Each view will be backed up by details supporting each of a candidate's policies. The transcript will include minor grammatical errors including punctuation, spelling, and tenses, all of which the participant will be asked to correct. Following this will be a mathematical task which will include converting mixed numbers to improper fractions at the difficulty of a fifth grade level. A memory recall task will then be administered to the participants asking them to recall as many of the details from the debate as possible.

Research has shown that riding a motorcycle can potentially be much more dangerous than operating a conventional vehicle. There are factors inherent in driving or riding a small two wheeled vehicle, such as a motorcycle, moped or even bicycle that can potentially decrease their ability to be seen or noticed by other drivers. This disadvantage is reflected in the disproportionate over-representation of injuries and/or fatalities incurred by this particular driving group. This creates a...
Show moreResearch has shown that riding a motorcycle can potentially be much more dangerous than operating a conventional vehicle. There are factors inherent in driving or riding a small two wheeled vehicle, such as a motorcycle, moped or even bicycle that can potentially decrease their ability to be seen or noticed by other drivers. This disadvantage is reflected in the disproportionate over-representation of injuries and/or fatalities incurred by this particular driving group. This creates a significant problem which deserves dedicated evaluation as to causative factors and/or influential variables. The following research was conducted with intentions to investigate the topic of motorcycle conspicuity so as to further explain the variables which positively contribute to a motorcycle being seen and to supplement the body of knowledge that currently exists on this topic. This study specifically evaluated the influence of sex, age, motorcycle lighting conditions, and vehicular daytime running lights upon one's ability to effectively detect a motorcycle within a "high fidelity" simulated environment. This research additionally sought to examine the feasibility and validity of using a novel fixed base "high fidelity" simulator for the evaluation of motorcycle conspicuity. The results from this research clearly indicate a link between vehicular DRLs and the effective detection of motorcycles and also support previous research as to the effectiveness of motorcycle DRLs. Additionally, these results suggest that as one ages, certain degradations in vision, cognition, and physiology occur which decrease one's performance in detecting and responding to a motorcycle. These findings additionally provide support for the use of a "high definition" fixed base simulator as a valid technology for the evaluation of motorcycle conspicuity.

Commarford, Patrick, Smither, Janan, University of Central Florida

Many researchers and speech user interface practitioners assert that interactive voice response (IVR) menus must be relatively short due to constraints of the human memory system. These individuals commonly cite Miller's (1956) paper to support their claims. The current paper argues that these authors commonly misuse the information provided in Miller's paper and that hypotheses drawn from modern theories of working memory (e.g., Baddeley and Hitch, 1974) would lead to the opposite conclusion...
Show moreMany researchers and speech user interface practitioners assert that interactive voice response (IVR) menus must be relatively short due to constraints of the human memory system. These individuals commonly cite Miller's (1956) paper to support their claims. The current paper argues that these authors commonly misuse the information provided in Miller's paper and that hypotheses drawn from modern theories of working memory (e.g., Baddeley and Hitch, 1974) would lead to the opposite conclusion – that reducing menu length by creating a greater number of menus and a deeper structure will actually be more demanding on users' working memories and will lead to poorer performance and poorer user satisfaction. The primary purpose of this series of experiments was to gain a greater understanding of the role of working memory in speech-enabled IVR use. The experiments also sought to determine whether theories of visual search and signal detection theory (SDT) could be used to predict auditory search behavior. Results of this experiment indicate that creating a deeper structure with shorter menus is detrimental to performance and satisfaction and more demanding of working memory resource. Further the experiment provides support for arguments developed from Macgregor, Lee, and Lam's dual criterion decision model and is a first step toward applying SDT to the IVR domain.

Show moreThe social transition to older adulthood can be challenging for elderly individuals and their families when isolation poses a threat to well-being. Technology is currently providing younger generations with an opportunity to stay in contact with social partners through the use of online social networking tools; it is unclear whether older adults are also taking advantage of this communication method. This study explored how older adults are experiencing online social networking. Specifically, this research addressed how older adults' attitudes towards online social networking are related to their expertise in using computers and the internet for this purpose. A survey methodological approach was employed whereby older adults aged 65 and over were recruited from senior centers across the Central Florida area to fill out a series of questionnaires. The Computer Aversion, Attitudes, and Familiarity Index (CAAFI) was used to measure attitudes and expertise with computers. The Internet Technical Literacy and Social Awareness Scale was used to measure interest and expertise with the internet. The relationship between older adults' use of online social networking and their attitudes and expertise was also investigated. Finally, social connectedness, (measured using the Social Connectedness Scale) and subjective well-being (measured using the Satisfaction with Life Scale) were measured to explore whether older adults receive a psychosocial benefit from using online social networking. Findings showed expertise and attitudes scores were strongly correlated, and these scores were also predictive of online social networking use. The results of this study may help social service providers for elderly individuals begin to understand the many factors associated with using new forms of technology.

Show moreIndividuals who have Attention Deficit/Hyperactivity Disorder (ADHD) experience adverse effects relating to driving; in addition, they experience deficits in scanning ability (Barkely et.al, 1996; Fischer et al., 2007; Munoz et al., 2003; Naja-Raja et al., 2007). The present study examined the effects of ADHD on eye tracking while driving. Ten participants consisting of both ADHD and individuals who do not have ADHD were included in this study. It was hypothesized that individuals who have ADHD will make more saccadic eye movements and thus shorter fixations than individuals who do not have ADHD. Furthermore, it was hypothesized that despite the fact that individuals who have ADHD will make more saccadic eye movements than individuals without ADHD, those individuals with ADHD will commit more traffic violations including collisions compared to individuals who do not have such a diagnosis. Findings indicated that hypothesis one was not supported by the data, whereas hypothesis two was supported in that ADHD individuals had more collisions and committed more traffic violations than the Control group. Additionally, upon conducting a Chi Square test for independence, a significant difference was found in the spatial distributions of the fixations between the ADHD and Control groups. The findings of this study could help better understand the factors involved in ADHD driving and could be used to train individuals with ADHD to become more aware of their surroundings and driving habits and thus become safer drivers.

One hundred participants from each of the three major monotheistic world religions were given a seven-question survey. The seven questions consisted of statements regarding the knowledge of their own religion, how the participants feel about terminally ill patients and those who have lost vital functions, and also whether or not they believe euthanasia is morally just. It was predicted that the participants who belong to Judaism and Islam viewed euthanasia as morally just and participants who belong to the Christianity viewed euthanasia as morally incorrect.

Show moreABSTRACT. This study examined the relationship between levels of sports team identification and sentence leniency. It was hypothesized that sharing the same sports team affiliation with the defendant would create bias in the form of juror leniency, and that highly identified fans would show more bias than lower identified fans. A case description of a hit and run accident, in which the defendant was described as a Tampa Bay Buccaneers fan, was read by 220 participants. Results showed a significant difference in recommended sentence length and levels of sympathy between the three groups (High Identity, Low Identity, & No Identity). However, contrary to the original hypothesis, participants who were highly identified with the Tampa Bay Buccaneers recommended a significantly longer sentence for the defendant and were less sympathetic than participants who had lower identification to the Buccaneers and those who had no Buccaneer identification. This paper discusses the relation of this finding with the Reverse Attractive Leniency Effect, as well as the Same-Sex Penalty Effect.

Show moreIn this thesis, a literature review was conducted in order to analyze the numerous sources that investigated the effects memory games may have on participants. Each study covered different scopes and methods in the field of cognitive improvement, which gave way to a variety of results used to create a comprehensive literature review. The experiments included in the literature review gathered evidence to find the effect that "brain" games had on memory and cognitive skills. An explanation and analysis were made on the brain's deterioration as it ages and the varying amounts of plasticity it contains. The overall perspective gained from the literature review allowed for a better understanding of the results of the surveys conducted for this thesis. The distinctive ways to encourage and improve brain health were researched, and a particular focus was placed on memory games regarding brain health factors. Overall, the benefits identified covered an increase in working memory, skills, and processing speed. However, there was an indication that the improvements were only for the tasks at hand. When research was conducted on transferable activities, there was little to no proof of the transferability of measured improvements. During the research portion of the thesis, a survey was conducted that involved 90 participants from the age of 60 and older on their perception of brain games. The results of the 9-question survey showed statistically significant correlations between the amount of times individuals had played memory games and their perception of both the simplicity and effectiveness of these games. Participants who had played games more frequently viewed the games as both more effective and simpler. Similarly, participants with more education perceived the games as being simpler. The male participants in this study were found to play memory games more frequently than the women. Overall, the correlations drawn from the results of the survey promote the enriched discussion on the subject of memory games and cognitive improvement.

Show moreAs the beneficial aspects of computers become more apparent to the elderly population and the baby boom generation moves into later adulthood there is opportunity to increase performance for older computer users. Performance decrements that occur naturally to the motor skills of older adults have shown to have a negative effect on interactions with indirect-manipulation devices, such as computer mice (Murata & Iwase, 2005). Although, a mouse will always have the traits of an indirect-manipulation interaction, the inclusion of additional sensory feedback likely increases the saliency of the task to the real world resulting in increases in performance (Biocca et al., 2002). There is strong evidence for a bimodal advantage that is present in people of all ages; additionally there is also very strong evidence that older adults are a group that uses extra sensory information to increase their everyday interactions with the environment (Cienkowski & Carney, 2002; Thompson & Malloy, 2004). This study examined the effects of having multimodal feedback (i.e., visual cues, auditory cues, and tactile cues) present during a target acquisition mouse task for young, middle-aged, and older experienced computer users. This research examined the performance and subjective attitudes when performing a mouse based pointing task when different combinations of the modalities were present. The inclusion of audio or tactile cues during the task had the largest positive effect on performance, resulting in significantly quicker task completion for all of the computer users. The presence of audio or tactile cues increased performance for all of the age groups; however the performance of the older adults tended to be positively influenced more than the other age groups due the inclusion of these modalities. Additionally, the presence of visual cues did not have as strong of an effect on overall performance in comparison to the other modalities. Although the presence of audio and tactile feedback both increased performance there was evidence of a speed accuracy trade-off. Both the audio and tactile conditions resulted in a significantly higher number of misses in comparison to having no additional cues or visual cues present. So, while the presence of audio and tactile feedback improved the speed at which the task could be completed this occurred due to a sacrifice in accuracy. Additionally, this study shows strong evidence that audio and tactile cues are undesirable to computer users. The findings of this research are important to consider prior to adding extra sensory modalities to any type of user interface. The idea that additional feedback is always better may not always hold true if the feedback is found to be distracting, annoying, or negatively affects accuracy, as was found in this study with audio and tactile cues.

Show moreThe goal of this research was to assess the ability of readers to determine the emotion of a passage of text, be it fictional or non-fictional. The research includes examining how genre (fiction and non-fiction) and emotion (positive emotion, such as happiness, and negative emotion, such as anger) interact to form a reading experience. Reading is an activity that many, if not most, humans undertake in either a professional or leisure capacity. Researchers are thus interested in the effect reading has on the individual, particularly with regards to empathy. Some researchers believe reading fosters empathy; others think empathy might already be present in those who enjoy reading. A greater understanding of this dispute could be provided by general recognition theory (GRT). GRT allows researchers to investigate how stimulus dimensions interact in an observer's mind: on a perceptual or decisional level. In the context of reading, this allows researchers to look at how emotion is tied in with (or inseparable from) genre, or if the ability to determine the emotion of a passage is independent from the genre of the passage. In the reported studies, participants read passages and responded to questions on the passages and their content. Empathy scores significantly predicted discriminability of passage categories, as did reported hours spent reading per week. Non-fiction passages were easier to identify than fiction, and positive emotion classification was affiliated with non-fiction classification.

Study 1 examined whether a Grocery List Task (GLT) distractor would load onto WMC. Forty-three participants completed a series of WMC tasks followed by the GLT. They then completed two driving trials: driving without the GLT and driving while completing the GLT. It was hypothesized that WMC would positively correlate with GLT performance. A bivariate correlation indicated that WMC was positively associated with performance on the GLT. Study 2 tested a series of distractor tasks (GLT, Tone Monitoring, and Stop Signal) to examine whether these three distractor tasks were also related to WMC, and if each of the distractor tasks would result in poor driving performance. Eighty-four participants were randomly assigned to the distractor conditions. Results indicated that GLT was related to WMC, but Tone Monitoring was not related to WMC. Also, engaging in each of the three distractor tasks led to significantly poorer driving performance. Study 3 evaluated whether rainy or clear weather conditions would affect the relationship between WMC and distracted driving using the same three distractor tasks (GLT, Tone Monitoring, and Stop Signal) as used in Study 2. Ninety-six participants were randomly assigned to the distractor conditions. Results showed that engaging in GLT while driving led to slower braking response times compared to not engaging in GLT driving while driving. Furthermore, WMC moderated the degree to which distraction impaired performance. The present findings clearly indicate that all three distractor tasks had a deleterious effect on driving performance. Furthermore, this effect of distraction on driving depends on many factors, including the type of distraction, the driving performance measure, and the individual's cognitive capabilities. Both theoretical and practical implications are discussed and directions for future research are presented.

Show moreStress and cognitive fatigue have become a pervasive problem, especially in Western society. Stress and cognitive fatigue can have deleterious effects not only on performance, but also on one's physical and mental health. This dissertation presents a study in which the aim is to investigate the effects of virtual nature on stress reduction and cognitive restoration. Specifically, this study assessed the effects of Immersion (Non-immersive, Semi-immersive, Fully-immersive) and Exploration (Passive vs Active) on stress reduction and cognitive restoration. Additionally, restoration from the most effective virtual nature environment was compared to that of taking an active coloring break. Eighty-three university students with normal color vision, depth perception and good visual acuity participated in this study. The overall findings of the study suggest that virtual nature is able to reduce stress and anxiety, generally the more immersive and interactive the better. Moreover, though both the those in the passive VR nature condition and those in the coloring condition reported a reduction in stress, only those in the passive VR nature condition exhibited the physiological changes indicative of stress reduction.

Show moreThe present study sought to determine the direction and degree to which occupations representative of all major occupational categories are viewed as age-typed (i.e., more appropriate for older or younger workers). The 60 occupations examined were the 12 most common and familiar occupations in each of five occupational categories used by the U.S. Census Bureau. I randomly assigned 365 participants to one of three survey conditions. Participants rated the feature centrality, proportional representation, normative age, and optimal performance age of 20 of the 60 occupations and the age-type of 20 different occupations. Results showed that participants reliably rated the occupations on a continuum from highly young-typed to highly old-typed. Occupations viewed as most appropriate for older workers included psychologists (clinical), bus drivers, and librarians, whereas those viewed as most appropriate for younger workers included recreation and fitness workers, bartenders, and hosts/hostesses. Interestingly, despite commonly held stereotypes that older workers are less competent than younger workers (Kite, Stockdale, Whitley, (&) Johnson, 2005), old-typed occupations were viewed as requiring higher competence than those viewed as young-typed. Additionally, roughly three times as many workers are needed to fill the most young-typed jobs compared to the most old-typed jobs (U.S. Census Bureau, 2000). Both of these findings suggest problems for an increasingly aging workforce (Administration of Aging, 2010). I also found that perceived proportional representation accounted for 79% of the variance in predicting the age-type of occupations. This suggests that people rely on general impressions of current worker ages, which supports career timetables theory's approach to the formation of occupational age-type. Implications for theory and research are discussed.

It has also been shown that individuals prefer blue and green colors because they are relaxing and prompt happy feelings (Guilford (&) Smith, 1959; Mahnke, 1996; Wexner, 1954). The question however, is what aspects of nature elicit these effects: is it the natural colors, the environmental setting, or both? The present experiment will examine the effects of color (Blue, Green, Black and White, (&) Natural) and environmental setting (Urban, Foliage, (&) Aquatic) on measures of attention, short term memory, and mood. Additionally, this study was designed to replicate the findings of Berman et.al 2008, all while rigorously controlling for the pictorial content of its manipulation. Due to the exploratory nature of this study, no specific hypotheses were made. However, the goal of this research was to (")tease apart(") the effects of color and environment on the restoration of cognitive abilities. One hundred and nineteen non-color blind individuals completed pre and post tests for the State Trait Anxiety Inventory (Form Y-1), Backwards Digit Span, and the Attention Network Task and viewed one of the twelve color/environmental setting picture sets between the pre and posttests. Results of the 2x3x4 Mixed ANOVAs do not support past research which suggests that natural environments are restorative in nature.

Show moreThis dissertation addresses a gap in the existing sustainability behavior research, by integrating research from the social sciences about environmental attitudes and knowledge with approaches from engineering regarding the characteristics of the built environment. Specifically, this dissertation explores the role of both environmental knowledge and design features within the built environment on building occupants' energy behaviors throughout the course of an environmental conservation campaign. Data were collected from 240 dormitory residents using a multi-phase questionnaire approach to study these factors and their combined impact within the context of environmental sustainability practices on UCF's campus. The results from a series of correlational and multiple regression analyses indicate that both the design components of the built environment and the attitudes held by individuals within that environment have a significant positive influence on behaviors. Furthermore, these findings indicated that this effect increases significantly when the two factors work together. Finally, the results show that pro- environmental attitudes and behaviors can be successfully targeted through a cue-based energy conservation campaign. By addressing a gap in the extant Human Factors research about the relationship between attitudinal factors and the built environment, this dissertation provides a unique contribution to the field and points the way towards development of promising solutions for encouraging sustainable behaviors.

Driving is a complex task that is highly reliant on attention. Research states that distrac-tions cause performance errors thus it is important to find ways to reduce driver distraction or assist drivers with ways to improve their cognitive resources if distraction is unavoidable.

Show moreDriving is a complex task that is highly reliant on attention. Research states that distrac-tions cause performance errors thus it is important to find ways to reduce driver distraction or assist drivers with ways to improve their cognitive resources if distraction is unavoidable. Moreover, research indicates that action video game players outperform non-players on lab-based tests of visual and cognitive abilities. However, research also exists that is contrary to these find-ings. Some researchers suggest that methodological deficiencies could be the cause of the significant findings in the literature. With such fervor of debate on the subject, the question re-mains of whether players acquire skills through playing action video games and if so can these games be used as research or training tools to enhance performance on realistic tasks. To answer this question, 45 male participants were tested using psychometric measures of spatial ability (Spatial orientation and visualization) and failures of attention (Cognitive Failures Question-naire), and then all participants drove four 10-minute drives in a driving simulator. The first drive was a practice, followed by a control drive. Participants were then distracted using a hands free phone conversation. Following that, participants completed a final control drive. Both overall video game experience and action video game experience was positively related to higher spatial ability scores. Additionally, participants with higher action game experience exhibited fewer lane deviations during driving overall, but not during the distraction condition. On the other hand, participants with higher spatial ability scores exhibited fewer lane deviations during the distraction condition, but not during the control drives. Furthermore, action video game ex-perience was not significant on the Cognitive Failures Questionnaire. Therefore, it was conclud-ed that individuals who have higher action game experience do not show improvements on any abilities of attention tested in this study. However, higher experience action video game players may perform better in simulated environments than those with less experience.

Show moreTo mitigate their estimated $300 billion in annual health-related losses, many companies have instituted workplace wellness initiatives designed to promote physical activity among their employees, improving the overall health of their workforce. Though middle-aged and older workers may potentially enjoy the greatest physical, stress and cognitive benefits from regular exercise, workplace wellness programs have been less successful in attracting such employees. This study developed and tested a 6-week exercise motivation intervention designed to meet the needs of sedentary, older working adults and to determine what non-physical benefits might result from increased levels of physical exercise. The intervention, based primarily on Self-Determination Theory, included feedback on individually-made, realistic, process-specific exercise goals that and provided guidance from knowledgeable exercise professionals in addition to support group of socially-similar individuals to aid in coping and adherence. The intervention was built and delivered entirely online to fit better with the sample's considerable time demands. The motivational intervention was delivered to a sample of 30 mostly-older working adults and was successful in significantly improving activity levels and overall affect while decreasing stress. No significant differences were detected in measures of personal resources, work engagement, work effort and task performance. The implications and recommendations for future research are discussed.

Show moreIt is often the case that emergency first responders are well equipped and trained to deal with a situation that involves evacuation of someone with a physical disability. However, emergency responders are not always the first line of defense, or they may be otherwise occupied with assisting others. This research examined the effects of instructions for emergency stair travel devices on untrained or novice users. It was hypothesized that through redesign of the evacuation instructions, untrained individuals would be able to successfully prepare an evacuation chair and secure someone with a disability more effectively and efficiently. A pre-post study design was used with an instructional redesign occurring as the manipulation between phases. There was an improved subjective understanding and improved performance metrics, such as reduced time on task and a reduction of the number of instructional glances, across three evacuation chairs when using the redesigned instruction sets. The study demonstrated that visual instruction style can account for a significant portion of explained variance in the operation of emergency stair travel devices. It also showed that improvements in instruction style can reduce time on task across device type and age group. The study failed to demonstrate that there was a performance decrement for older adults in comparison to younger adults because of the cognitive slowing of older adult information processing abilities. Results from this study can be used to support future iterations of the Emergency Stair Travel Device Standard (RESNA ED-1) to ensure that instructional design is standardized and optimized for the best performance possible.

Show moreA preponderance of research points to the detrimental effects of distraction on driving performance. An interesting question is whether practice can improve distracted driving. The results from the few longitudinal simulator-based research studies conducted on driving distraction have been inconclusive. This may be because practice effects could be confounded with participants adapting to driving in the simulator. Therefore, participants in the current studies were trained until performance reached a steady state prior to introducing the distracters.In this dissertation, two single-subject design studies were used to investigate the effects of training on distracted driving. The first study included two participants who experienced several different types of distracters. In the second study distracters were introduced before and after the training phase. The two distracters selected for Study 2 included conversing on a handheld phone and texting on a touchscreen phone continuously while driving in a city scenario. Previous research has not compared texting to phone, has had relatively littleexamination of texting and driving alone, and has primarily focused on hands-free phones and on highway settings. Participants drove on a city route which they had previously memorized to add realism to the driving task. Measures collected included speed maintenance, lane deviations/position errors, stop errors, and turn errors in both studies. In Study 2, subjective workload and reaction time were also collected.Findings indicated that training improved performance substantially for all participants in both studies compared to the initial baseline. Participants who experienced six and even nine sessions of the initial baseline did not necessarily improve more than those who only had three sessions. Performance for some participants did not improve in the initial baseline. The lower error levels in training remained fairly stable in subsequent baselines showing that actual learning did occur. Texting had higher error levels than phone both pre and post-training. There were no practice effects noticed for the distracters post-training for any of the participants, and in fact errors increased across sessions for phone and especially texting in Study 2. Training helped improve performance during the phone distraction more so than texting overall, although this varied for different dependent measures. Although errors were reduced after training in the distracter phases, the data actually showed that the performance difference between the baselines and the distracters pre-training was smaller than the differences post-training. Based on these findings, it is recommended that researchers conducting driving simulation research systematically train their participants on driving the simulator before they begin data collection.
