Self-congruity, Preference, and Pathfinder: An Examination of News Media Outlet Knowledge Structures
Generally, warnings that are perceived as being urgent produce lower response times. One technique for increasing perceived urgency of a warning is called looming, where the signal increases in or more dimensions over time. Looming warning signals have been shown to produce low response times, likely because the recipient perceives the signal as a potential approaching threat, prompting defensive reactions (Graziano and Cooke, 2006).
The present study evaluates the effect of veridical (intensity increases at the rate of closure with the lead vehicle) and high urgency (intensity increases at a rate of Time to Collision minus 0.5 seconds) looming FCW, as well as a static FCW, on drivers’ brake reaction times in the presence of a secondary texting task. Participants’ brake reaction times were recorded as they followed a lead car in a driving simulator, encountering multiple sudden-braking events across the five conditions (a control condition as well as four counterbalanced conditions using a secondary texting task). In the four conditions with a secondary task, participants received no FCW, static FCW, veridical FCW, and high-urgency FCW, respectively. Performance data was analyzed using a repeated measures ANOVA, and a series of pairwise comparisons were then made using Bonferroni corrected pairwise t-tests.
The presence of a visually and manually distracting secondary task (texting) seems to diminish the performance of the looming signals as compared to previous studies that did not use a distraction component. While looming FCW do seem to effectively lower BRTs when the driver is distracted, it is recommended that further research investigate the relationship between secondary task types and their respective levels of distraction, and the effectiveness of auditory looming FCW.
on-restriction of movement during the pre-shot routine. Results were analyzed using 2x2 Within-Subjects Analysis of Variance. For shooting performance, there was an interaction (approaching significance) such that participants were more affected by pressure when allowed to execute their pre-shot routine. For kinematic variables, significant interactions between pressure and movement restriction were found for elbow-knee cross correlations and there were significant main effects of variability of the acceleration of both the elbow and knee angles. In all kinematic measures, participants exhibited more “novice-like” patterns of movement under pressure when movement was not restricted during the pre-shot routine. Primary results indicate promising evidence that motor control may be a mediating variable between pressure and performance and bring into question the value of a pre-shot routine in basketball.
This thesis project focused on comparing different aspects of traditional in person<br/>learning and remote online learning and how these two types of learning environments impact<br/>students in the elementary grade levels, specifically Kindergarten through sixth grade. For this<br/>thesis project, I conducted podcast interviews in which I interviewed many different teachers at<br/>different elementary grade levels. These teachers all had experience at some point with both<br/>traditional in person learning and remote online learning. All of these teachers have many<br/>different levels of experience and teach in various districts across the state of Arizona. The<br/>purpose of this thesis project was to learn and understand how these two different types of<br/>learning environments impact both students and teachers. Throughout this thesis project, I have<br/>become increasingly passionate in my future teaching career. I have learned so much about<br/>myself through this process and was able to improve my communication skills through<br/>conducting these interviews as well as significantly increase my knowledge on both in person<br/>learning and remote online learning.
patient recovery time. It is a surgical procedure done by using long reached tools and an
endoscopic camera to operate on the body though small incisions made near the point of
operation while viewing the live camera feed on a nearby display screen. Multiple camera
views are used in various industries such as surveillance and professional gaming to
allow users a spatial awareness advantage as to what is happening in the 3D space that is
presented to them on 2D displays. The concept has not effectively broken into the
medical industry yet. This thesis tests a multi-view camera system in which three cameras
are inserted into a laparoscopic surgical training box along with two surgical instruments,
to determine the system impact on spatial cognition, perceived cognitive workload, and
the overall time needed to complete the task, compared to one camera viewing the
traditional set up. The task is a non-medical task and is one of five typically used to train
surgeons’ motor skills when initially learning minimally invasive surgical procedures.
The task is a peg transfer and will be conducted by 30 people who are randomly assigned
to one of two conditions; one display and three displays. The results indicated that when
three displays were present the overall time initially using them to complete a task was
slower; the task was perceived to be completed more easily and with less strain; and
participants had a slightly higher performance rate.
The study used a mixed-methods experimental design and involved a three-session VR STEM learning intervention. The quantitative data was collected through the intervention by survey questionnaire, session quiz, and pre- and post-tests, while the interviews were taken after the intervention. The structural equation modeling method was used to explore the relationships among factors in the VR learning experience. Longitudinal quantitative comparisons were conducted with the multiple imputation method. Its purpose was to evaluate the changing magnitude of factors across sessions. After quantitative analysis, interview transcripts were analyzed. They were used to triangulate or provide context for understanding of quantitative results.
The results showed that motivation and engagement play a critical mediation role in an effective VR learning experience. While individuals’ psychological responses and motivation may significantly increase in a VR learning experience for novelty, the novelty effect may not steeply decrease when individuals are becoming familiar with the novelty. This phenomenon is more observable in a VR condition having a high degree of immersion and embodiment. In addition, novelty does not necessarily increase learning achievement. The increase of learning achievement is more dependent on a match between the learning content and the learning method. The embodied learning method is appropriate for instructing difficult knowledge and spatial knowledge. Reserving enough time for reflection is important to deep learning in a VR environment.
