When discussing human factors and performance, researchers recognize stress as a factor, but overlook mood as contributing factor. To explore the relationship between mood, stress and cognitive performance, a field study was conducted involving fire fighters engaged in a fire response simulation. Firefighter participants completed a stress questionnaire, an emotional state questionnaire, and a cognitive task. Stress and cognitive task performance scores were examined before and after the firefighting simulation for individual cognitive performance depreciation caused by stress or mood. They study revealed that existing stress was a reliable predictor of the pre-simulation cognitive task score, that, as mood becomes more positive, perceived stress scores decrease, and that negative mood and pre-simulation stress are also positively and significantly correlated.

This study investigated the effect of two different preparation methods on hitting performance in a high&ndashfidelity; baseball batting simulation. Novice and expert players participated in one of three conditions: observation (viewing a video of the goal action), visualization (hearing a script of the goal action), or a no&ndashpreparation; control group. Each participant completed three different hitting tasks: pull hit, opposite&ndashfield; hit, and sacrifice fly. Experts had more successful hits, overall, than novices. The number of successful hits was significantly higher for both the observation and visualization conditions than for the control. In most cases, performance was best in the observation condition. Experts demonstrated greater effects from the mental preparation techniques compared to novices. However, these effects were mediated by task difficulty. The difference between experts and novices, as well as the difference between the observation and visualization conditions was greater for the more difficult hitting task (opposite&ndashfield; hitting) than for the easier hitting task (sacrifice fly). These effects of mental preparation were associated with significant changes in batting kinematics (e.g., changes in point of bat/ball contact and swing direction). The results indicate that mental preparation can improve directional hitting ability in baseball with the optimal preparation methods depending on skill&ndashlevel; and task difficulty.

Due to the sudden outbreak of COVID-19, communities were forced to isolate themselves in their homes and take many safety precautions. Through this isolation, people experienced a lack of social interactions on a daily basis and increased boredom. Due to the new feelings of the pandemic experience, many found themselves to be engaging significantly more with technology and social media. Doing so helped many to interact with others or spend their extra time. Since people were engaging so much more with technology, there were distinct positive and negative outcomes. Some social media use helped cope with experiencing feelings of isolation by the COVID-19 pandemic, while it may have caused feelings of anxiety for others. Engaging with others helped humanize the experience of relying on social media as a replacement for receiving human interaction on a daily basis (Zhen, 2021). College students were specifically impacted by isolation in a social manner, but were also affected in other areas such as in their academic life. Social media became a critical tool for college students in coping with the challenges of the pandemic (Zhao, 2020). This paper will explore some of the ways in which social media has helped college students cope during the COVID-19 pandemic and how it may have had more negative effects on others. This will be explored through reviewing current literature and research. Research findings will be compared to interviews conducted for the purpose of this project. Three different college students were interviewed and asked a series of questions regarding their personal experience with COVID-19, mental health, and social media. The interview responses will be reviewed according to current research to spot any similarities in findings.

The recent popularity of ChatGPT has brought into question the future of many lines of work, among them, psychotherapy. This thesis aims to determine whether or not AI chatbots should be used by undergraduates with depression as a form of mental healthcare. Because of barriers to care such as understaffed campus counseling centers, stigma, and issues of accessibility, AI chatbots could perhaps bridge the gap between this demographic and receiving help. This research includes findings from studies, meta-analyses, reports, and Reddit posts from threads documenting people’s experiences using ChatGPT as a therapist. Based on these findings, only mental health AI chatbots specifically can be considered appropriate for psychotherapeutic purposes. Certain chatbots that are designed purposefully to discuss mental health with users can provide support to undergraduates with mild to moderate symptoms of depression. AI chatbots that promise companionship should never be used as a form of mental healthcare. ChatGPT should generally be avoided as a form of mental healthcare, except to perhaps ask for referrals to resources. Non mental health-focused chatbots should be trained to respond with referrals to mental health resources and emergency services when they detect inputs related to mental health, and suicidality especially. In the future, AI chatbots could be used to notify mental health professionals of reported symptom changes in their patients, as well as pattern detectors to help individuals with depression understand fluctuations in their symptoms. AI more broadly could also be used to enhance therapist training.

A literature search revealed that previous research on the Attentional Blink (AB) has not examined the role of salience in AB results. I examined how salience affects the AB through multiple forms and degrees of salience in target 1 (T1) and target 2 (T2) stimuli. When examining increased size as a form of salience, results showed a more salient T2 increased recall, attenuating the AB. A more salient T1 did not differ from the control, suggesting the salience (increased size) of T2 is an important factor in the AB, while salience (increased size) of T1 does not affect the AB. Additionally, the differences in target size (50% or 100% larger) were not significantly different, showing size differences at these intervals do not affect AB results. To further explore the lack of difference in results when T1 is larger in size, I examined dynamic stimuli used as T1. T1 stimuli were presented as looming or receding. When T1 was presented as looming or receding, the AB was attenuated (T2 recall at lag 2 was significantly greater). Additionally, T2 recall was significantly worse at lags three and four (showing a larger decrease directly following the attenuated AB). When comparing looming and receding against each other, at lag 2 (when recall accuracy at its lowest) looming increased recall significantly more than receding stimuli. This is expected to be due to the immediate attentional needs related to looming stimuli. Overall, the results showed T2 salience in the form of size significantly increases recall accuracy while T1 size salience does not affect the AB results. With that, dynamic T1 stimuli increase recall accuracy at early lags (lag 2) while it decreases recall accuracy at later lags (lags 3 and 4). This result is found when the stimuli are presented at a larger size (stimuli appearing closer), suggesting the more eminent need for attention results in greater effects on the AB.

A core component of leadership is being able to motivate and influence people to perform at the highest levels they are capable of. Being able to perform well in most industries requires people to put effort into their work, bypass surface level impulses, and engage deeper levels of cognitive processes when making decisions. This study looked at two treatments, an expectation and a social incentive, and its effects on cognitive reflection test (CRT) scores and time taken to complete this test. Although it appeared that receiving a leaderboard and expectation treatment improved cognitive reflection test score, these results were not statistically significant. It appeared that a leaderboard and expectation treatment increased time put into taking the test after removing certain data, but these results were also not statistically significant. After some transformation of the data, there may be an effect that leaderboards have on deeper level cognitive engagement if time and effort put into the test is controlled for properly, but this will have to be observed further in future studies.

There has been an ongoing debate between the relative deterrent power of certainty and severity on deceptive and criminal activity, certainty being the likelihood of capture and severity being the magnitude of the potential punishment. This paper is a review of the current body of research regarding risk assessment and deception in games, specifically regarding certainty and severity. The topics of game theoretical foundations, balance, and design were covered, as were heuristics and individual differences in deceptive behavior. Using this background knowledge, this study implemented a methodology through which the risk assessments of certainty and severity can be compared behaviorally in a repeated conflict context. It was found that certainty had a significant effect on a person’s likelihood to lie, while severity did not. Exploratory data was collected using the dark triad personality quiz, though it did not ultimately show a pattern.
