Prior research has shown that positive psychological states and attitudes are known outcomes in students who are engaged on their college campus. Although many studies prove this to be evident, literature lacks examination between these two variables. The purpose of the current study was to find a cognitive link between student engagement and the measured outcomes of self-esteem, college self-efficacy, college affiliation, and levels of optimism/pessimism.

Show morePrior research has shown that positive psychological states and attitudes are known outcomes in students who are engaged on their college campus. Although many studies prove this to be evident, literature lacks examination between these two variables. The purpose of the current study was to find a cognitive link between student engagement and the measured outcomes of self-esteem, college self-efficacy, college affiliation, and levels of optimism/pessimism. The study proposed that there is a process of developing an internal sense of presence on campus, which occurs in those students that are actively engaged in activities outside of the classroom. Individual personality traits are additionally measured as a variable for tendencies of involvement. Measurements of presence level in students were analyzed by administering a Campus Presence Scale, modified from the Witmer & Singer Presence Scale. The study subscales that examine levels of student engagement and its outcomes were measured in an online questionnaire format via Qualtrics. A total of 371 students at the University of Central Florida participated in the study. This study hypothesized that students who spend more time on campus engaged in co-curricular activities would display higher levels of presence development. The study also sought a flow of development in these processes, hypothesizing that campus presence mediates the actions in which students engage and their psychological well-being and attitudes towards their institution. Analyses in SPSS were used to examine these relationships. Results indicated that presence is significantly correlated with higher student self-esteem, self-efficacy, college affiliation, and optimism. Results also showed that those involved with student organizations and those who regularly attend campus events are significantly more extroverted and have higher levels of presence, college affiliation and self-efficacy

In this study we examined the differences of performance of various input devices on a steering task. Two paths were created, one easy and one hard, with the harder path having more turning points to navigate with one of three different input devices: mouse and keyboard, Xbox 360 controller, and a joystick. Participants were also exposed to low or high stress conditions. High stress was caused by playing loud short bursts of music over headphones worn by participants during testing. Results...
Show moreIn this study we examined the differences of performance of various input devices on a steering task. Two paths were created, one easy and one hard, with the harder path having more turning points to navigate with one of three different input devices: mouse and keyboard, Xbox 360 controller, and a joystick. Participants were also exposed to low or high stress conditions. High stress was caused by playing loud short bursts of music over headphones worn by participants during testing. Results indicated the mouse and keyboard performed better in all cases. There was no significant difference between the Xbox controller and joystick. No differences were found in the low and high stress conditions. Differences in sex were found, even when controlling for video game experience. These findings indicate that the mouse and keyboard is the best device to use on a steering task.

A 2 (devices: ECG, MSB2) x 4 (epochs: baseline 1, 1-back task, baseline 2, 3-back task) repeated measures factorial design was conducted. The participants were simultaneously equipped to the MSB2 and an electrocardiogram (ECG). The results of this study validated the MSB2 for the use in a cognitive task. The study suggests that fitness-tracking devices with similar sampling rates and features are candidates for further exploration as alternatives to ECG, in hope of making the inclusion of physiological data in psychological research more available and accessible.

The results showed that while skin tone had little effect, gender and ethnicity were more indicative. Therefore our study seeks to re-test the relationship between skin tone and consumer service perception as well as the effects of ethnicity and tipping behavior, and if a consumer's cultural identity strength plays a role in consumer perception. We examined the differences across ethnicities i.e. White, Hispanic, and African American. Specifically we were interested in any potential differences across skin tone (light skinned vs. dark skinned) within African American and Hispanic service providers. Firstly we sought out stock images that portrayed easily identifiable ethnicities. We exposed the respondents to those images in which we asked them to identify the ethnicity of the image as a manipulation check for ethnicity. In the actual study, all respondents were given the same service scenario with the image of one of the ten (White, light or dark skinned Hispanic, light or dark skinned African American, male or female) stock photos. Respondents were asked to rate the service quality, satisfaction, and tip amount. The data was analyzed as a 2 way independent-groups design.

Show moreTheory of Mind (ToM) has repeatedly been defined as the ability to understand that others believe their own things based on their own subjective interpretations and experiences, and that their thoughts are determined independently from your own. In this study, we wanted to see if individual differences in ToM are capable of causing different perceptions of an individual's interactions with human like robotics and highlight whether or not individual differences in ToM account for different levels of how individuals experience what is called the "Uncanny Valley phenomenon" and to see whether or not having a fully developed theory of mind is essential to the perception of the interaction. This was assessed by inquiring whether or not individuals with Autism Spectrum Disorder (ASD) perceive robotics and artificially intelligent technology in the same ways that typically developed individuals do; we focused on the growing use of social robotics in ASD therapies. Studies have indicated that differences of ToM exist between individuals with ASD and those who are typically developed. Comparably, we were also curious to see if differences in empathy levels also accounted for differences in ToM and thus a difference in the perceptions of human like robotics. A robotic image rating survey was administered to a group of University of central Florida students, as well as 2 surveys - the Autism Spectrum Quotient (ASQ) and the Basic Empathy Scale (BES), which helped optimize a measurement for theory of mind. Although the results of this study did not support the claim that individuals with ASD do not experience the uncanny valley differently than typically developed individuals, there were significant enough results to conclude that different levels of empathy may account for individual differences in the uncanny valley. People with low empathy seemed to have experienced less of an uncanny valley feeling, while people with higher recorded empathy showed to experience more of an uncanny valley sensitivity.

Show moreCollege life is a unique experience in the life of many young adults that presents many challenges for which they might not be prepared, including living away from home and adapting to a new social and academic environment. In particular, these experiences may be particularly adverse for students with social phobia and may be predictors of academic and social problems, and may even predict dropout. The purpose of the present research is to identify possible connections between socially phobic tendencies and the social, emotional, and overall well-being of college students. Social phobia itself is an unnecessary and overwhelming fear of being scrutinized by others (National Institute of Mental Health 2009). By implementing the use of four psychological tests: the Social Phobia and Anxiety Inventory, Positive and Negative Affect Schedule, College Affiliation Questionnaire, and Life Orientation Test, this research sought to investigate the correlations existing between college students' self-reports on these measures through the use of the UCF Sona system. Students' personal characteristics and demographics were also examined correlationally along with their self-reports on all four measures. A total of 165 participants were used in this study. After gathering descriptive statistics from each test and their demographics, correlations were run between the four tests and then between demographic information and tests. The results showed social phobia having a positive correlation with negative affect and a negative relationship with positive affect. In turn, negative emotion was correlated with a lowered overall life orientation and a more pessimistic mindset. No strong correlations were identified between psychological tests and student characteristics as was previously thought. Overall, there are definite indicators that social anxiety has a negative impact on one's quality of life and emotions, however, more research needs to be done with more diverse sampling and different methodology to see if there is a link between particular student characteristics and prevalence rates of social anxiety within those characteristic subsets.

Show moreResearch has shown that in Human-Human Interactions kinematic information reveals that competitive and cooperative intentions are perceivable and suggests the existence of a cooperation bias. The present study invokes the same question in a Human-Robot Interaction by investigating the relationship between the acceleration of a virtual robot within a virtual reality environment and the participants perception of the situation being cooperative or competitive by attempting to identify the social cues used for those perceptions. Five trials, which are mirrored, faster acceleration, slower acceleration, varied acceleration with a loss, and varied acceleration with a win, were experienced by the participant; randomized within two groups of five totaling in ten events. Results suggest that when the virtual robot's acceleration pattern were faster than the participant's acceleration the situation was perceived as more competitive. Additionally, results suggest that while the slower acceleration was perceived as more cooperative, the condition was not significantly different from mirrored acceleration. These results may indicate that there may be some kinematic information found in the faster accelerations that invoke stronger competitive perceptions whereas slower accelerations and mirrored acceleration may blend together during perception; furthermore, the models used in the slower acceleration conditions and the mirrored acceleration provide no single identifiable contributor towards perceived cooperativeness possibly due to a similar cooperative bias. These findings are used as a baseline for understanding movements that can be utilized in the design of better social robotic movements. These movements would improve the interactions between humans and these robots, ultimately improving the robot's ability to help during situations.

Show moreThe belief that intentions are hidden away in the minds of individuals has been circulating for many years. Theories of indirect perception, such as the Theory of Mind, have since been developed to help explain this phenomenon. Conversely, research in the field of human kinematics and event perception have also given rise to theories of direct perception. The purpose of the study was to determine if intentionality can be directly perceived rather than requiring inferential processes. Prior research regarding kinematics of cooperative and competitive movements have pointed toward direct perception, demonstrating participants can accurately judge a movement as cooperative or competitive by simply observing point-light displays of the isolated arm movements. Considering competitive movements are often performed faster than cooperative movements, speed was perturbed for the purpose of this study to determine if participants are relying on cues or if they can indeed perceive a unique kinematic pattern that corresponds to intentionality. Judging the clips correctly despite perturbation would suggest perception is direct. Additionally, we hypothesized judgments accuracy would be higher in the presence of two actors pointing to the use of interpersonal affordances. Twenty-eight participants from the University of Central Florida were asked to judge 40 clips presented in random order including: normal or perturbed competitive actions with one or two actors; normal or perturbed cooperative actions with one or two actors. Percent correct and reaction time data were analyzed on SPSS using a repeated measures ANOVA. Results rejected the hypothesis that social perception is direct and supported indirect perception, indicating participants relied on cues to make judgments, and provided potential support for the interpersonal affordance hypothesis.

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.

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 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 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.

Show moreOlder adults experience more difficulties completing goal directed movements than younger adults. The reasons for this have not been completely elucidated within the research lit-erature; however, it is thought that age related movement differences are due to at least one of three possible reasons. The current study investigated the influence of these three hypotheses: (1) biomechanical changes (limbs, joints, or muscles), (2) sensory feedback processing ability, or (3) differences in overall movement strategy on movement kinematics. Additionally, physical activi-ty is known to improve both physical and cognitive functioning and staying cognitively active may also attenuate age-related declines in cognitive ability; thus the current study also examined the impact of physical and mental fitness on movement performance across the lifespan. Both active and sedentary young and old adults completed different experimental conditions to de-termine how biomechanical ability, sensory processing ability, and individual differences impact different kinematic aspects of movement performance. Participants completed two different Fitts' pointing tasks where difficulty was manipulated by either increasing biomechanical effort and/or amount of feedback processing needed to complete each movement. Results indicated that distance impacted movement more than width for all participants indicated by a greater ID-MT slope. While increasing age was associated with an increases slope, the larger finding was that age increased the overall time. Thus, it was concluded that distance and width constraints are processed by similar processes regardless of age, but these processes slow with age. Cardio-vascular fitness attenuated declines in the distance condition while mental fitness attenuated those in the width condition. Further supporting a theory of differential movement constraints.
