OPENNESS TO EXPERIENCE: A PREDICTOR OF TECHNOLOGY USE AT ANY AGE?
Title
OPENNESS TO EXPERIENCE: A PREDICTOR OF TECHNOLOGY USE AT ANY AGE?.
Creator
Ojalvo, Olivia, Chin, Matthew, University of Central Florida
Abstract / Description
Technology is an integral part of both modern culture and day-to-day communication. Older adults' relationships with technology are completely different than younger adults' because of the way they have learned to incorporate it into their lives. Past research has shown that certain personality traits can predict technology use in younger adults. The current research hopes to take that finding and see if it applies to older adults, too. Four hypotheses were generated. Participants took a...
Show moreTechnology is an integral part of both modern culture and day-to-day communication. Older adults' relationships with technology are completely different than younger adults' because of the way they have learned to incorporate it into their lives. Past research has shown that certain personality traits can predict technology use in younger adults. The current research hopes to take that finding and see if it applies to older adults, too. Four hypotheses were generated. Participants took a survey that consisted of five different scales and measures. Participants also were asked to answer demographic questions. Independent-sample t-tests and bivariate correlations were run on the data. Results showed that general technology use was not significantly correlated to a participant's age. There were significant correlations between the two age groups and psychological well-being, feelings of attachment to peers, technology use subscales and sensation seeking subscales. Future studies should examine the possible relationship of technology use subscales amongst the older population and their attitudes towards technology.

Show moreThe Internet is becoming the main source for various tasks, from learning, to working, and shopping. There are many websites one can use to shop. Almost all stores have a website from which you can order anything you might want. As online shopping becomes more prominent, it is important to understand the effects of the Internet and its product reviewers and, specific to this study, consumer decision making. This study seeks to understand the effect of star ratings and valence on review perception between the different cognitive levels of individuals. Recognition review perception, and intent to purchase were being measured. Results showed that need for cognition did have an effect on accuracy of recognition and perceived valence. Need for cognition and congruency as well as actual valence had an effect on perceived valence. Need for cognition, actual valence, and congruency all had an effect on purchase intention. This research is important because it is relevant to a growing trend around the world. Technology is already integrated into nearly everyone's lives and it is only going to more so as we continue to evolve. Just as it is becoming more common for people to receive education from online institutions, and for employers to use more Internet based applications, it is only natural consumers will continue the trend of purchasing items online. Learning the social and cognitive influences of online reviews on perception and purchasing intentions is something everyone needs to be aware of.

Show moreThe use of virtual teams (VTs) in the workplace has increased rapidly as companies seek to coordinate the collaboration of geographically dispersed employees effectively. This study involved an experimental comparison of VTs and face-to-face teams engaged in coopetition. Coopetition occurs when a relationship is characterized by simultaneous cooperation and competition. This study differed from previous research because many previous studies of team coopetition place their focus on traditional face-to-face teams and fail to touch upon the intricacies of VT coopetition. Because of this, investigating the intricacies of coopetition among VT members is an essential addition to the large body of research on face-to-face teams. This study examined team coopetition through separate measures of competitiveness and cooperativeness. The constructs competitiveness and cooperativeness were measured separately instead of together on a single continuum. This method determined team members' coopetitive proclivities, the balance between one's tendency to perform behaviors directed toward achieving a self-serving goal or goals and one's tendency to perform behaviors directed toward achieving a group-serving goal or goals within the context of a coopetitive relationship. Team members' coopetitive proclivities were examined through a combination of videogame play and electronic surveys. All participants in this experiment were female. No significant differences between the coopetitive proclivities of virtual and face-to-face teams were found. We found that the ratings of competence that participants received from their partners tended to be lower under the virtual condition. We found that extroverted team members were more likely to cooperate. We also found that the ratings of competitiveness that participants received from their partners were negatively correlated with the ratings of desirability for future collaboration (i.e., team viability) that participants received from their partners. Further, it was determined that the ratings of cooperativeness that participants received from their partners were positively correlated with the ratings of team viability that participants received from their partners. Additional results indicated a positive relationship between team members' self-reported levels of agreeableness and the ratings of competence that participants received from their partners. Results also indicated a positive relationship between team members' self-reported levels of openness and the ratings of competence that participants received from their partners. This paper discusses the implications of these results and possible directions for future study.

Show moreThe objective of this thesis was to investigate intersectional (categorical/social) invisibility and the extent to which this phenomenon occurs in a comparison of dominant (i.e., Caucasian), and non-dominant (African-American and Latino) social/ethnic groups. It has been found that intersectional invisibility occurs among African-American women with respect to Caucasian men and women, and African American men (Sesko & Biernat, 2010), but little of this research has been done regarding Latinas. Thus, this experiment aims to not only examine whether Latinas are also subject to intersectional invisibility among dominant (i.e., Caucasian) and non-dominant (i.e., African American and/or Latino) groups, but to determine whether the theory can be extended to perceptions between non-dominant groups such as African-Americans and Latinos. Determining whether intersectional invisibility occurs among Latinas, moreover, may provide theoretical and practical insights of what advantages/disadvantages Latinas may particularly endure as members of the rapidly growing Latino population in the U.S.

Show moreThe purpose of this thesis is to explore how surface engagement through touch affects perception of stimuli and mood. Researchers have found psychological, physiological and cognitive benefits associated with exposure to and interaction with nature. Stress Reduction Theory with Psychoevolutionary framework, and Attention Restoration Theory are often used to explain and interpret results. However, studies that focus on individuals with negative perspectives of nature find a positive affective response to nature is not universal. Rather, individuals respond differently based on their own experience with nature. Childhood exposure and culture have been found to influence attitudes towards nature. Theories of embodied cognition emphasize the importance of previously learned associations and embodied states have been found to influence judgment, experience of emotions, and physiological states. To assess whether an individual's attitude towards nature influences the embodiment of a positive or negative state, participants were randomly assigned to come into physical contact with one of four surfaces with their feet: grass, fake grass, dirt and cement. Individuals affective, cognitive and physical relationship with nature was measured with the Nature Relatedness Scale. Change in perception of neutral stimuli and mood before and after surface exposure were measured. Results suggested surfaces influenced mood in different ways, however the effects on perception were unclear. A participant's perspective of nature did not seem to influence mood change depending on surface type. Future research is needed to assess whether the shift in mood was based on metaphors of language, priming from surface texture, or a result of complex interaction between bodily sensations and cognition.

Show moreThis experiment was run to see whether the educational presentations done at zoos and other educational facilities are effectively changing patrons' negative misconceptions about the animals they were seeing. Participants were invited to attend one of three educational presentations, where they were exposed to either a low, intermediate or high level of interaction involving a bat. I hypothesized that regardless of the level of interaction, participants would learn the information, but that a higher level of interaction would cause the biggest perceptual change in terms of how participants felt about the bat and the highest degree of learning. Across the board, participants increased their factual knowledge, with no significant differences between the baseline, taxidermy or live bat conditions. The taxidermy group had the largest difference in attitude change, but the live bat did have a role in influencing participants' views as to whether bats were beneficial to the environment. These results imply that educational facilities can use a taxidermy bat or a live bat with their patrons and depending on how they utilize the inclusion of the interactive stimulus, it will cause perceptual and educational differences.

Show moreCompanion animals now serve as more than tools for human use, they have become family. Many individuals now spend increasingly more money on animals than in years past and are more likely to acknowledge the animal as a family member. With this change in roles many humans have become more empathetic to animal cruelty. Studies have been conducted to examine various aspects of animal cruelty and how it relates to humans. However, few have examined attitude change regarding animal abuse. If attitudes can be positively changed in adults, these individuals are in a position to pass the information onto their children. Adults are also currently in the position to make changes in legislature regarding humane treatment of animals. An experiment was conducted which examined adults' attitudes toward animal abuse and whether they can be changed. Text information was examined as a variable for attitude change. Additionally visual aids in the form of photographs were used in conjunction with and separate from the text information as variables. Two types of photographs were used: images of companion animals by themselves or the same animals accompanied by adult humans. The text information used was adapted from an ASPCA presentation obtained, with permission, from the Orange County ASPCA. The power point presentation included information on the connection between animal violence and violence toward humans, how to help stop animal cruelty and how to report it. Six conditions were created using the three variables. iii It was found that pictures have an immediate effect on attitude change and information affects individuals in certain measures but not others. On all measures, images had more of an effect than information alone. Only when the text was accompanied by a picture, did it produce a significant change. Attitudes regarding the treatment of animals saw an immediate increase in both conditions in which images of humans and animals were present. Additionally, images of animals alone immediately increased attitudes regarding treatment of animals. This difference does not appear to increase further over time. Images of animals alone appear to aid in immediately altering individuals' sense of continuity with animals. The attitude that animals and humans share some commonalities and exist in relation to each other could assist in adoption campaigns by allowing the potential owners to place themselves with the animals they are adopting. However, over time information combined with images of humans and animals significantly increase this sense of commonality. The applications for the results depend on what type of attitude one desires to change and how soon the change has to occur. The present research reveals that images appear to affect attitude change regarding companion animals and the way they are treated more than text information.

Show moreEyewitness testimony has as long history in the court system, and is very persuasive to juries. Jurors are hard pressed to ignore a witness' assertion of a perpetrator's identity. However, the juror's perception of eyewitness testimony is problematic as it has been documented as inaccurate and unreliable in numerous experiments. With the advent of DNA testing and efforts such as The Innocence Project, it has become apparent that faulty eyewitness accounts are central to many wrongful convictions. The intent of this thesis was to explore how law enforcement can facilitate more accurate eyewitness accounts via their interview process. Research suggests that a key problem in the current interviewing system is "post-event information," or outside information introduced by leading questions, exposure to police conversations or other witnesses' accounts. This information can contaminate a witness's memories of events and lead them to report things they did not see. The current experiment explores the effects of 1) warning and educating witnesses about suggestibility and 2) interviewing with leading or open-ended questions. Accuracy scores were then compared for each condition. The hope was to gain insight into methods for improving accurate recall of events and reducing memory contamination from "post-event information."

Show moreOwnership of mobile devices, such as tablets and smartphones, has quickly risen in the last decade. Unsurprisingly, they are now being integrated into the training and classroom setting. Specifically, the U.S. Army has mapped out a plan in the Army Learning Model of 2015 to utilize mobile devices for training purposes. However, before these tools can be used effectively, it is important to identify how the tablets' unique properties can be leveraged. For this dissertation, the touch interface and the interactivity that tablets afford were investigated using a procedural-motor task. The procedural motor task was the disassembly procedures of a M4 carbine. This research was motivated by cognitive psychology theories, including Cognitive Load Theory and Embodied Cognition. In two experiments, novices learned rifle disassembly procedures in a narrated multimedia presentation presented on a tablet and then were tested on what they learned during the multimedia training involving a virtual rifle by performing a rifle disassembly on a physical rifle, reassembling the rifle, and taking a written recall test about the disassembly procedures. Spatial ability was also considered as a subject variable.Experiment 1 examined two research questions. The primary research question was whether including multiple forms of interactivity in a multimedia presentation resulted in higher learning outcomes. The secondary research question in Experiment 1 was whether dynamic multimedia fostered better learning outcomes than equivalent static multimedia. To examine the effects of dynamism and interactivity on learning, four multimedia conditions of varying levels of interactivity and dynamism were used. One condition was a 2D phase diagram depicting the before and after of the step with no animation or interactivity. Another condition utilized a non-interactive animation in which participants passively watched an animated presentation of the disassembly procedures. A third condition was the interactive animation in which participants could control the pace of the presentation by tapping a button. The last condition was a rifle disassembly simulation in which participants interacted with a virtual rifle to learn the disassembly procedures. A comparison of the conditions by spatial ability yielded the following results. Interactivity, overall, improved outcomes on the performance measures. However, high spatials outperformed low spatials in the simulation condition and the 2D phase diagram condition. High spatials seemed to be able to compensate for low interactivity and dynamism in the 2D phase diagram condition while enhancing their performance in the rifle disassembly simulation condition.In Experiment 2, the touchscreen interface was examined by investigating how gestures and input modality affected learning the disassembly procedures. Experiment 2 had two primary research questions. The first was whether gestures facilitate learning a procedural-motor task through embodied learning. The second was whether direct touch input using resulted in higher learning outcomes than indirect mouse input. To examine the research questions, three different variations of the rifle disassembly simulation were used. One was identical to that of Experiment 1. Another incorporated gestures to initiate the animation whereby participants traced a gesture arrow representing the motion of the component to learn the procedures. The third condition utilized the same interface as the initial rifle disassembly simulation but included (")dummy(") gesture arrows that displayed only visual information but did not respond to gesture. This condition was included to see the effects (if any) of the gesture arrows in isolation of the gesture component. Furthermore, direct touch input was compared to indirect mouse input. Once again, spatial ability also was considered. Results from Experiment 2 were inconclusive as no significant effects were found. This may have been due to a ceiling effect of performance. However, spatial ability was a significant predictor of performance across all conditions. Overall, the results of the two experiments support the use of multimedia on a tablet to train a procedural-motor task. In line with vision of ALM 2015, the research support incorporating tablets into U.S. Army training curriculum.

Show moreThe goal of this research was to examine the effectiveness of persuasive language in the protective action recommendation of an emergency warning, which instructs people how to prepare and stay safe. Study 1 was a pilot study, which suggested that participants were able to make distinctions between hurricane categories. In study 2, the presence of fear language and second-person personal pronouns (i.e., (")you(")) in a recommendation was manipulated. Overall, fear language was more influential than a pronoun on risk perceptions. To understand how context influences risk perceptions, participants in study 3 made decisions after each piece of information received. The severity of the hurricane increased, decreased, or stayed the same before decision point 2 and a recommendation containing fear or neutral language was presented before decision point 3. Those who read the fear message were more likely to be in the danger control process than those in the neutral language condition, which suggested that the fear message emphasized threat but did not diminish participants' perception of efficacy. Behavioral compliance with the warning was high in all conditions. In terms of change in perceived threat from decision point 2 to 3, participants in the decrease condition who read the fear appeal had the largest increase in perceived threat. In contrast, the hurricane increasing in intensity may be fear provoking enough that a fear appeal does not enhance risk perceptions. When examining individual differences, high Need for Cognition women had the largest increase in perceived message persuasiveness in the decrease and increase conditions.Phrasing guidelines for emergency management are discussed, along with the theoretical contributions of using social psychological methodology to examine emergency warnings. While individual differences are important predictors of warning interpretation, future research needs to reconcile the conundrum of emergency management's current limitations regarding individualized warnings.

Show moreThere is abundant anecdotal evidence substantiating Mori's initial observation of the "uncanny valley", a point at which human response to non-human entities drops sharply with respect to comfort (Mori, 1970), and the construct itself has a long-standing history in both Robotics and Psychology. Currently, many fields such as design, training, entertainment, and education make use of heuristic approaches to accommodate the anticipated needs of the user/consumer/audience in certain important aspects. This is due to the lack of empirical substantiation or, in some cases, the impossibility of rigorous quantification; one such area is with respect to the user's experience of uncanniness, a feeling of "eeriness" or "wrongness" when interacting with artefacts or environments. Uncanniness, however, continues to be defined and measured in a largely subjective way, and often after the fact; an experience or product's uncanny features are pointed out after the item has been markedly avoided or complained about by the general public. These studies are among the first seeking to determine a constellation of personality traits and physiological responses that incline the user to have a more frequent or profound (")uncanny" reaction when presented with stimuli meeting the criteria for a level of "eeriness". In study 1, 395 adults were asked to categorize 200 images as uncanny, neutral, pleasant, or other. In Study 2, physiological and eye-tracking data was collected from twenty two adults as they viewed uncanny, neutral and pleasant images culled from study 1. This research identifies components of the uncanny valley related to subjective assessment, personality factors (using the HEXACO and Anthropomorphic Tendencies Scale), and biophysical measures, and found that traits unique to Emotionality on the HEXACO inventory, compounded with a form of anthropomorphism demonstrates a level of relationship to the subjective experience of uncanny stimuli. There is evidence that HEXACO type and forms of anthropomorphic perception mediates the biophysical expression and the subjective perception of the stimuli. In keeping with psychological hypotheses, stimuli to which the participants had greatest response centered on death, the threat of death, or mismatched/absent facial features.

Show moreThis dissertation investigated the effects of complex backgrounds on mental rotation. Stimulus familiarity and background familiarity were manipulated. It systematically explored how familiarizing participants to objects and complex backgrounds affects their performance on a mental rotation task involving complex backgrounds. This study had 113 participants recruited through the UCF Psychology SONA system. Participants were familiarized with a stimulus in a task where they were told to distinguish the stimulus from 3 other stimuli. A similar procedure was used to familiarize the backgrounds. The research design was a 2 stimulus familiarity (Familiarized with the Target Stimulus, not familiarized with the Target Stimulus) by 2 background familiarity (Familiarized with Target Background, not familiarized with Target Background 1) by 2 stimulus response condition (Target Stimulus, Non-Target Stimulus) by 3 background response condition (Target Background, Non-Target Background, Blank Background) by 12 degree of rotation (0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330) mixed design. The study utilized target stimulus and target background familiarity conditions as the between-subjects variables. Background, stimulus, and degree of rotation were within-subjects variables. The participants' performance was measured using reaction time and percent of errors. Reaction time was computed using only the correct responses. After the familiarization task, participants engaged in a mental rotation task featuring stimuli and backgrounds that were present or not present in the familiarization task. A 2 (stimulus familiarization condition) by 2 (background familiarization condition) by 2 (stimulus response condition) by 3 (background response condition) by 12 (degree of rotation) mixed ANOVA was computed utilizing reaction time and percent of errors. Results suggest that familiarity with the Target Background had the largest effect on improving performance across response conditions. The results also suggest that familiarity with both the Target Stimulus and Target Background promoted inefficient mental rotation strategies which resulted in no significant differences between participants familiarized with neither the Target Stimulus nor the Target Background. Theoretical conclusions are drawn about stimulus familiarity and background familiarity. Future studies should investigate the effects of long term familiarity practice on mental rotation and complex backgrounds.

Abstract / Description
It has been previously established that when engaged in a difficult attention intensive task, which involves repeating information while blocking out other information (the dichotic listening task), participants are often able to report hearing their own names in an unattended audio channel (Moray, 1959). This phenomenon, called the cocktail party effect is a result of words that are important to oneself having a lower threshold, resulting in less attention being necessary to process them ...
Show moreIt has been previously established that when engaged in a difficult attention intensive task, which involves repeating information while blocking out other information (the dichotic listening task), participants are often able to report hearing their own names in an unattended audio channel (Moray, 1959). This phenomenon, called the cocktail party effect is a result of words that are important to oneself having a lower threshold, resulting in less attention being necessary to process them (Treisman, 1960). The current studies examined the ability of a person who was engaged in an attention demanding task to hear and recall low-threshold words from a fictional story. These low-threshold words included a traditional alert word, (")fire(") and fictional character names from a popular franchise(-)Harry Potter. Further, the role of stimulus degradation was examined by including synthetic and accented speech in the task to determine how it would impact attention and performance.In Study 1 participants repeated passages from a novel that was largely unfamiliar to them, The Secret Garden while blocking out a passage from a much more familiar source, Harry Potter and the Deathly Hallows. Each unattended Harry Potter passage was edited so that it would include 4 names from the series, and the word (")fire(") twice. The type of speech present in the attended and unattended ears (Natural or Synthetic) was varied to examine the impact that processing a degraded speech would have on performance. The speech that the participant shadowed did not impact unattended recall, however it did impact shadowing accuracy. The speech type that was present in the unattended ear did impact the ability to recall low-threshold, Harry Potter information. When the unattended speech type was synthetic, significantly less Harry Potter information was recalled. Interestingly, while Harry Potter information was recalled by participants with both high and low Harry Potter experience, the traditional low-threshold word, (")fire(") was not noticed by participants. In order to determine if synthetic speech impeded the ability to report low-threshold Harry Potter names due to being degraded or simply being different than natural speech, Study 2 was designed. In Study 2 the attended (shadowed) speech was held constant as American Natural speech, and the unattended ear was manipulated. An accent which was different than the native accent of the participants was included as a mild form of degradation. There were four experimental stimuli which contained one of the following in the unattended ear: American Natural, British Natural, American Synthetic and British Synthetic. Overall, more unattended information was reported when the unattended channel was Natural than Synthetic. This implies that synthetic speech does take more working memory processing power than even an accented natural speech. Further, it was found that experience with the Harry Potter franchise played a role in the ability to report unattended Harry Potter information. Those who had high levels of Harry Potter experience, particularly with audiobooks, were able to process and report Harry Potter information from the unattended stimulus when it was British Natural. While, those with low Harry Potter experience were not able to report unattended Harry Potter information from this slightly degraded stimulus. Therefore, it is believed that the previous audiobook experience of those in the high Harry Potter experience group acted as training and resulted in less working memory being necessary to encode the unattended Harry Potter information. A pilot study was designed in order to examine the impact of story familiarity in the attended and unattended channels of a dichotic listening task. In the pilot study, participants shadowed a Harry Potter passage (familiar) in one condition with a passage from The Secret Garden (unfamiliar) playing in the unattended ear. A second condition had participants shadowing The Secret Garden (unfamiliar) with a passage from Harry Potter (familiar) present in the unattended ear. There was no significant difference in the number of unattended names recalled. Those with low Harry Potter experience reported significantly less attended information when they shadowed Harry Potter than when they shadowed The Secret Garden. Further, there appeared to be a trend such that those with high Harry Potter experience were reporting more attended information when they shadowed Harry Potter than The Secret Garden. This implies that experience with a franchise and characters may make it easier to recall information about a passage, while lack of experience provides no assistance. Overall, the results of the studies indicate that we do treat fictional characters in a way similarly to ourselves. Names and information about fictional characters were able to break through into attention during a task that required a great deal of attention. The experience one had with the characters also served to assist the working memory in processing the information in degraded circumstances. These results have important implications for training, design of alerts, and the use of popular media in the classroom.

Show moreThis study investigated the development of trust between strangers interacting via avatars in virtual worlds. The first part of the study analyzed perceived trustworthiness based on the visual appearance of avatars; the second part makes observations of two strangers self-disclosing information via avatars in a virtual world; the third part analyzed an experimental situation of two individuals interacting via avatars, where avatar appearance was changed and participants were recruited based on their experience with interacting with others via avatars. Findings showed that perceived trustworthiness does vary based on the visual appearance of the avatar. A positive relationship was found for self-disclosure and experience, in that those who have previously chosen to participate in a virtual world were more likely to share more detailed information about themselves. Non-significant differences in self-disclosure were found for avatar appearance; however, experience in using virtual worlds was significantly different for the willingness to share information before engaging in a task: experienced participants shared more information than inexperienced participants. This suggests that self-disclosure might be influenced by appearance at the point of formation in that the experienced are willing to overlook the avatar, and less so when there are other sources of information to base trust-behavior on (Altman (&) Taylor, 1973; Nowak (&) Rauh, 2006).Recommendations were made for modifications for similar experiments trying to validate an objective measure of trust, and for continued research in the development of trust between strangers interacting via avatars

Show moreLive simulations play an important role in allowing users to practice and develop skills they learn in training. Although live simulations are playing an increasingly important role in training, ways to improve them are not well understood or documented. In order to improve the efficacy of live simulation and maximize results from funds spent on training; this research examines the relationship between the affective variables of the participants and their performance in the live simulation. Prior to participating in the instructor development live simulation used in this study two training preference scales were administered to a group of trainees. These scales measured the trainees' locus of control and immersion tendencies. During the live simulation the trainees' performance was evaluated by a panel of expert observers. The trainees also self-reported their performance through the use of a self-rating instrument. Analysis of the data revealed significant positive correlations between the trainees' internal locus of control and their performance in the simulation, both self-reported (p=0.026) and as reported by the expert observers (p=0.033). The correlation between immersion tendency scores and performance in the live simulation were mixed; while not always statistically significant they did reveal some slight positive correlation. This research did provide a number of lessons learned and implications for instructional and simulation developers wishing to employ live simulation in a training environment. These include performance of sub-populations within the greater population of subjects, consideration of roles assigned to participants, and the need to increase presence within the live simulation. Application of these lessons learned can reduce training costs and/or improve the effectiveness of live simulation in a training environment, this in turn can be of significant benefit to instructional and simulation designers. Additionally, understanding these relationships can lead to better assignments of roles or activities within live simulation and improve the transfer of experience from live simulation training to on the job performance. However, additional research needs to be conducted in order to make more conclusive statements regarding the most appropriate affective variable that would allow for predicting transfer of the simulated experience to the 'real' world, the individuals who would benefit most from live simulation, and to develop additional prescriptive methods for improving live simulation utilized in training environments.
