Description
Muslim refugees and Muslim immigrants, and undocumented immigrants have been a prominent part of American culture and have been woven into the history of the United States. Both group's presence in the United States has elicited rhetoric from U.S citizens and U.S public officials. One may infer that the narrative of Muslim refugees and Muslim immigrants overlaps the narrative of undocumented immigrants living in the United States. Both Muslim refugees and immigrants as well as unauthorized immigrants, are criminalized in the United States, or are associated to crime by default of their faith and or their legal status. The association that Muslim refugees and Muslim immigrants, and undocumented immigrants have with crime, based on their rhetoric, has elicited a policy from the United States government as well. The United States government has responded to a presumed threat that both groups pose to U.S. citizens and the nation by means of aggressive legislation, both local and federal. In this research paper, past and present discourse on Muslim refugees and Muslim immigrants and undocumented immigrants was analyzed to determine each of the group's narrative; the mainstream media, newspapers and photographic images, was also considered to determine the narrative of both groups. Based on the discourse on Muslim refugees and Muslim immigrants and on undocumented immigrants, the media portrayal of both groups, and on the change of public policy one may assert that the narratives of both groups overlaps; as both Muslim refugees and immigrants and unauthorized immigrants are seen as a possible threat to the American people.

Description
Trust was measured for a target profile that varied the target's religion and costly signaling behavior. Subjects were primed with a threat, romance, or neutral response previous to viewing the profile to determine if this had any effect on their trust ratings of the target. Participants were drawn from MTurk with ages ranging from 18 to 75 (M= 33.2) and various religious backgrounds (including 210 Christians, 190 atheists/agnostics, and 92 other religious believers). Participants were presented with the threat, romance, or neutral vignette, shown the target profile, and asked to rate the target's trustworthiness. There was no main effect of the vignette condition (p = .088) or costly signaling (p = .099) on the target's trustworthiness. There was a main effect of target religion (p = .006) wherein the Muslim target was trusted more than the Catholic target. These findings do not replicate previous findings on religion, costly signaling, and trust.

Description
Pain has been found in previous research to have a noticeable effect on people’s ability to perform creative tasks. While limited studies in this field exist, most of this work has focused on convergent thinking through the use of compound remote associates tasks (CRAT). In order to investigate how acute pain might affect divergent creative cognition involving a wider answer space, the current study was conducted using an alternate uses task (AUT) during an algometer-based pain intervention. It was found that acute pain did not have a significant effect on accuracy in the CRAT nor on problem solving abilities in the AUT but notably, participants in the pain condition were more likely to say that they solved problems in the CRAT through insight rather than by an analytical approach. This work demonstrates the need for more research in this field to better understand the relationship between creative cognition and pain.

Description
Behavioral, electrophysiological, and neuroimaging evidence has demonstrated that multiple object tracking (MOT) tasks draw upon visual perception, attention, and working memory cognitive processes. Functional neuroimaging studies identified the middle temporal visual area (MT+/V5) as one of several brain regions associated with MOT in humans. MT+/V5 is thought to be responsible for processing motion from visual information, regulating smooth pursuit eye movements, and encoding memory for motion. However, it is unclear how MT+/V5 interacts with attention and working memory performance processes during MOT. To investigate this question, the right MT+/V5 region was identified in 14 neurotypical subjects using structural magnetic resonance imaging (sMRI). The right MT+/V5 was stimulated using intermittent theta-burst stimulation (iTBS), continuous theta-burst stimulation (cTBS), and sham transcranial magnetic stimulation (TMS) using a within-subjects design. Average MOT performance was measured before and 5-min, 30-min, and 60-min after each stimulation protocol. There was no significant difference in average MOT performance across time, regardless of the stimulation condition.

Description
The present study researched the systematic biases in working memory and how items interact with each other in working memory. The first goal of the study was to assess whether working memory representations of one another or systematically interact. This was tested by the repulsion bias in the representations. The second goal was to test whether the interaction is modulated by attentional priority. Attended items exhibited a weaker repulsion bias indicating that attention helped to protect the representation from the impact of the un-attended item.The average mean error for the unattended item was 3.68º while for the attended item it was 2.19º. These results are consistent with the hypothesis that items in working memory systematically interact with each other and further suggests that the main theories in working memory that do not assume interactions need to be updated.

Description
The locus coeruleus-norepinephrine system (LC-NE) has been argued to play a vital role in task engagement and attention control by the adaptive gain theory (Aston-Jones & Cohen, 2005). One of the central claims of this theory is that tonic LC activity exhibits a quadratic relationship with task performance. Pupil dynamics have been correlated to LC-NE activity via primate intracranial recordings in ways that provide evidence for the adaptive gain theory. Due to the small size and location of the LC, less is known about LC functioning in humans, leading to a desire to find valid, noninvasive psychophysiological proxies to study this structure. In this paper we performed a replication of Murphy, Robertson, Balsters, & O’Connell (2011) to gather evidence on whether pupil fluctuations and the P3 event-related potential are viable markers for measuring tonic and phasic LC-NE activity in humans. A sample of 33 subjects from the Arizona State University human subjects pool provided usable electroencephalogram and pupillometry data collected during an auditory oddball task. Our analyses largely correspond with those found in Murphy et al. (2011) showing some evidence that pupillometry and P3 can be utilized when studying the LC. Moving forward we will reproduce the full set of analyses from Murphy et al. (2011) with our dataset.

Description
The purpose of this project was to extend Whitehead 2016 to determine what neural substrates supported conflict-mediated learning. Unfortunately, as a result of the COVID-19 pandemic we were unable to address this. To repurpose the collected data, an analysis of which features of the Flanker task subjects were learning was conducted. Specifically, we wanted to know if subjects were learning by using the flanking stimuli to predict the central target or vice versa. Over 14 blocks comprised of 120 trials, we found that subjects made more stroop errors than flanker and target errors, indicating subjects were responding to stimuli in context of the flanker rather than the stroop effect.
