Description
Throughout my experience in college, I learned many different techniques to communicate effectively. Most professors emphasized the importance of speaking clearly, and the ability to influence others. Dr. Kashiwagi piqued my interest when he explained his thoughts on how he wanted us to communicate to him. The criteria were simple, speak to him in a way that he could easily understand, without having to think. If thinking took place for him in the conversation, he determined that the person spoke too complexly and that his understanding of the student was low. After hearing this in class, I thought back to past conversations with my managers. I then wondered if I explained things clearer or simplified my wording, would things have gone better? I was also curious about simplicity in communication through writing, and how different presentations of information affected understanding. To further analyze these issues, I explored multiple research reports on verbal communication. Furthermore, I set up an experiment to test two common types of visual communication. The research concludes that Dr. Kashiwagi's theory was indeed correct, simplicity in conversation reduces miscommunication. The effectiveness of simplicity in written communication was partially proven by the survey results. The results indicated that the time required to fully understand a given topic dropped significantly if the information was depicted in a simplified format (list format). The more complex paragraph (textbook format) did have a higher level of understanding. However, the participants rated the textbook format job objectives as more complex, and stressful. After gathering the research, and running the experiment it can be concluded that by simplifying verbal communication, there are negligible differences in understanding of the topic, but the time of understanding decreases significantly.

Description
This thesis investigates the potential of life cycle analysis for more sustainable sourcing strategies in organizations. Using the example of the College of Lake County (CLC) in Illinois, I study how life-cycle analysis can help to improve the procurement of products and services in higher education. Currently, CLC's purchasing team does not understand how sourcing affects operational and environmental performance. In addition, CLC's purchasing team does not communicate effectively with other departments from a product utilization standpoint. The objective of this research is to analyze CLC's current product procurement process and to assess the feasibility of implementing life cycle analysis tools. Further, I evaluate different life cycle analysis tools and provide recommendations to CLC about the applicability of these tools so that they may be implemented into the university in the future. First, I find that both the procurement and IT department at CLC are not familiar with life-cycle analysis tools and hence, do not know about the life cycle of their processes and services. Second, I identify professional life cycle analysis tools relevant for CLC. Two software options, GaBi and SimaPro, are discussed. Finally, I suggest six steps for a successful implementation of life cycle analysis at CLC: (1) form an interdisciplinary team, (2) analyze demand and collect additional data, (3) conduct a product life cycle analysis using a software tool, (4) define which products to analyze further, (5) conduct life cycle costing analysis with the same software tool, and (6) utilize these results for decisions and delegation of responsibility.

Description
Problem solving is a crucial skill needed to accomplish everyday tasks and overcome potential obstacles. One way to measure individual differences in problem solving ability is through performance differences on multiply-constrained problem solving tasks. Multiple cognitive processes are involved in multiply-constrained problem solving. An individual uses prospective metacognitive monitoring judgments to gauge future allocation of resources before engaging in the necessary semantic search. Problem solvers also vary in their semantic search strategies, and use either an active analytical strategy or a passive insight strategy to arrive at asolution. Prospective metacognitive monitoring judgments and solution strategies are two aspects of the problem solving process that occur at specific points in the process while motivation influences problem solving throughout the process. The goal of this study is to examine prospective metacognitive judgments, problem solving accuracy, solution strategy, and motivation in multiply-constrained problem solving. Motivation was manipulated using a performance based monetary incentive. Participants self reported prospective Feeling-of-Knowing judgments after brief exposure to the problem, and solution strategy ratings after each problem. No significant differences were found to support the effect of motivation on problem solving accuracy, prospective metacognitive judgments, relative accuracy, or solution strategies. Significant differences were found between groups when comparing the number of problems skipped, indicating that participants were sensitive to the incentive structure. The findings suggest that motivation may not be an overarching mediator in multiply-constrained problem solving or problem solving may require a specific type of incentive structure to increase accuracy. However, little is known in the research literature about the type of incentive structure needed to consistently increase individual motivation.

Description
In everyday life, unfocused attention can be detrimental to life either through driving vehicles, cutting vegetables, and learning new languages. In order to increase sustained attention, Binaural Beats were introduced. Binaural Beats have two different frequency tones which oscillate to produce different effects. Each of these beats operates at different frequencies thus having different sound production: theta, delta, alpha, beta, and gamma. In the experiment beta Binaural Beats with frequencies of 200 and 216 Hertz, Hz (unit of measurement for frequency), were used with a control of 200 Hz flat noise. The experiment utilized the psychomotor vigilance task to measure changes in response times and utilized Affectiva to measure changes in facial musculature. The response times were then analyzed to explain why the Binaural Beats condition had significantly shorter response times compared to the control group throughout the task. In terms of emotional change, some trends were noticed for the Binaural Beats and the control condition; however, none of the trends were significant. Moving forward with the experiment, an increased number of participants can be recorded to strengthen the validity and test different frequencies of Binaural Beats for accuracy.

Description
Recognition memory is examined by exposing a person to a stimulus and later prompting them with the same stimulus to examine their ability to accurately acknowledge that the stimulus was previously encountered (Kahana, 2012). In recognition memory, confidence ratings are taken during the testing phase to assess how confident the participant is that the old-new judgment that they just made is accurate (Busey et al., 2000). Confidence is a metacognitive assessment about the accuracy of perception of decision making based on the amount, speed, and clarity of thoughts that come to mind (Dunlosky and Metcalfe, 2008). The goal of the current study is to better understand how assessing recognition memory using a variety of test procedures influences memory accuracy using the signal detection theory and adding multiple confidence scales that vary in granularity. Based on the previous literature, it is hypothesized that; 1) tasks ordered sequentially will produce greater recognition accuracy (d') than the simultaneous (dual task) condition; 2) confidence scale of 3 points will produce a larger d' than the 7 point scale, and the 7 point scale will produce a larger d' than the 100 point scale; and 3) task mode (ordered vs. sequenced) will interact with confidence scale granularity to predict memory accuracy, such that sequential judgments lessen demands on working memory that come from maintaining an increasing number of decision criteria in comparison to the dual task. Results indicated all hypotheses were not upheld. The findings suggest that taxing working memory may not affect decisional accuracy on a recognition task incorporating confidence judgments.

Description
It is a well-established finding in memory research that spacing or distributing information, as opposed to blocking all the information together, results in an enhanced memory of the learned material. Recently, researchers have decided to investigate if this spacing effect is also beneficial in category learning. In a set of experiments, Carvalho & Goldstone (2013), demonstrated that a blocked presentation showed an advantage during learning, but that ultimately, the distributed presentation yielded better performance during a post-learning transfer test. However, we have identified a major methodological issue in this study that we believe contaminates the results in a way that leads to an inflation and misrepresentation of learning levels. The present study aimed to correct this issue and re-examine whether a blocked or distributed presentation enhances the learning and subsequent generalization of categories. We also introduced two shaping variables, category size and distortion level at transfer, in addition to the mode of presentation (blocked versus distributed). Results showed no significant differences of mode of presentation at either the learning or transfer phases, thus supporting our concern about the previous study. Additional findings showed benefits in learning categories with a greater category size, as well as higher classification accuracy of novel stimuli at lower-distortion levels.

Description
The frontostriatal reward circuit serves an underlying role in reward processing, cognitive planning, and motor control in the context of achieving a goal. Furthermore, research suggests a relationship between the reward circuits and behavior expressed in Attention Deficit Hyperactivity Disorder (ADHD); however, the specific structural differences of the reward circuits in those with ADHD remain ambiguous. Diffusion tensor imaging (DTI) techniques were used to analyze diffusion weighted magnetic resonance imaging (DWI) data in order to examine the structural connectivity of frontostriatal reward pathways in ADHD adolescents compared to typically developing (TD) adolescents. It was hypothesized that measures of impulsivity would be predicted by white matter tract integrity measures in frontostriatal tracts related to affective processing (ventromedial prefrontal cortex to ventral striatum, vmPFC) in adolescents with ADHD, and that there would be reduced tract integrity in tracts related to executive control (dorsolateral prefrontal and anterior cingulate cortex—dlPFC and ACC, respectively). Frontostriatal tracts as well as the hippocampus and amygdala were examined in relation to age and impulsivity using both correlation and regression models. Results indicated that impulsivity declined with age in the TD group while no significant trend was identified for the ADHD group. The hypotheses were not supported and results for both predictions on the affective and executive circuits showed opposite trends from what was expected.

Description
Prospective memory refers to the ability to form and carry out an intention. Prospective memory can be further divided into the subcategories of episodic and habitual prospective memory, which differ in their task demands and electrophysiological components. The focus of the present study is on habitual prospective memory, which is the ability to routinize and consistently fulfill intentions that occur repeatedly. This skill is especially useful for populations with impaired executive functioning and/or memory deficits, such as those with acquired brain injuries. The purpose of this study is to analyze the performance of an undergraduate population on a habitual prospective memory task in order to create a baseline model for comparison with a clinical population. Evidence of habitization to the prospective memory component of the task was discovered, as demonstrated by speeded ongoing-task response times and reduced interference to prospective memory cues. Ongoing task accuracy and prospective memory cue detection were very high, while commission errors were very few, demonstrating ease of the task for neurotypical populations. We speculate that people with acquired brain injuries will not show as significant of a quickening of response times, nor such accurate performance on prospective memory cue trials or the commission error phase.
