Description
Individual differences in working memory capacity partly arise from variability in attention control, a process influenced by negative emotional content. Thus, individual differences in working memory capacity should be predictive of differences in the ability to regulate attention in emotional contexts. To address this hypothesis, a complex-span working memory task (symmetry span) was modified so that negative arousing images or neutral images subtended the background during the encoding phase. Across three experiments, negative arousing images impaired working memory encoding relative to neutral images, resulting in impoverished symmetry span scores. Additionally, in Experiment 3, both negative and arousing images captured attention and led to increased hit rates in a subsequent recognition task. Contrary to the primary hypothesis, individual differences in working memory capacity derived from three complex span tasks failed to moderate the effect of negative arousing images on working memory encoding across two large scale studies. Implications for theories of working memory and attention control in emotional contexts will be discussed.

Description
Working memory capacity and fluid intelligence are important predictors of performance in educational settings. Thus, understanding the processes underlying the relation between working memory capacity and fluid intelligence is important. Three large scale individual differences experiments were conducted to determine the mechanisms underlying the relation between working memory capacity and fluid intelligence. Experiments 1 and 2 were designed to assess whether individual differences in strategic behavior contribute to the variance shared between working memory capacity and fluid intelligence. In Experiment 3, competing theories for describing the underlying processes (cognitive vs. strategy) were evaluated in a comprehensive examination of potential underlying mechanisms. These data help inform existing theories about the mechanisms underlying the relation between WMC and gF. However, these data also indicate that the current theoretical model of the shared variance between WMC and gF would need to be revised to account for the data in Experiment 3. Possible sources of misfit are considered in the discussion along with a consideration of the theoretical implications of observing those relations in the Experiment 3 data.

Description
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.

Description
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.

Description
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.

Description
Music is a pervasive element of human culture that plays a significant role in our social interactions and goals. The current research regarding the evolutionary nature of music remains divisive, with several groups making competing claims about whether music is an evolved trait and, if it is, what function it may serve for survival and reproduction. In an attempt to further define the multiple dimensions of the evolution of music, this study focuses on a specific methodology for determining the relationship between improvisational musical ability, cognitive fitness, and sexual attraction. In Part 1 of this research, piano musicians completed working memory tests and provided 30-second recordings of improvisation. These recordings were heard by participants in Part 2 of the experiment, who rated both the music and a random facial image from an independent database paired with each song. The data revealed that perceived quality of music is positively associated with attractiveness, with a significant effect observed in males of moderate baseline attractiveness. Although the relationship between some working memory measures and musical improvisational ability proved not to be statistically significant, auditory working memory span yielded a marginally significant result. The overall results are consistent with a sexual selection theory of the evolution of musical improvisation and suggest appropriate avenues for future research.
