This study examines the effects of neurotensin (NT) receptor sites on the sensation of visceral pain. Previous work by researchers has found, through the use of NT analogs, that visceral pain is closely associated with NT receptor 2 (NTSR2). This study tested 70 genetically modified mice. The mice were either missing NTSR1, NTSR2, or were wild-type (WT) mice that were not missing any NT receptors. The mice were injected intraperitoneally with either saline or acetic acid then observed for a 60 minute period and writhing behavior was recorded. Twenty four hours later activity levels were recorded in the open field assay. We found that contrary to previous research, NTSR2 is not solely responsible in the sensation of visceral pain. We also found that NTSR1 plays a more significant role than NTSR2, contrary to previous research. Additionally, we found that the NT receptors may be affected by age related factors. The findings of this study suggest that NTSR2 does in fact play a role in the sensation of visceral pain but that NTSR1 may modulate the degree of activation of NTSR2. It can also be concluded that age may have a role in the effectiveness of NTSR sites in visceral pain. This information allows for further research to analyze possible age-dependent effects of NT receptor sites that could alter the possible usefulness of NT analogues in the future.

The purpose of this study was to gain a better understanding of false memories and Need for Cognition (NFC). The relationship was examined using a typical misinformation paradigm where participants viewed a video clip which depicted a museum burglary and were later presented with an auditory narrative that contained misleading information about the video they previously saw. Half of the participants were exposed to warnings of misinformation. Additionally, the effect of question type (e.g., central, peripheral, and neutral) was taken into account. A main effect for NFC was found indicating that high NFC individuals had fewer false memories for the originally witnessed event than low NFC individuals. It was also found that memory for central details was better than for peripheral details. Furthermore, an interaction between warning and question type showed that when a warning was present, memory for the misleading peripheral details was stronger. Overall, the results demonstrate that there is a difference between high and low NFC individuals and the way memory is processed in the misinformation paradigm. Additionally, the results of this study reaffirm the notion that post-event information can hinder an eyewitness’s memory for an original event.

The present study was conducted to investigate whether returning veterans feel ostracized (excluded and ignored) and if they experience its immediate negative impact (reflexive pain response and thwarted basic needs) on university campuses. Additionally, this study was designed to investigate veteran students’ feelings of perceived burdensomeness, and three caveats of student engagement: student faculty engagement, community-based activities, and transformational learning opportunities. Participants in the study were 118 civilian and veteran students at the University of North Florida. All data were collected through a world wide web surveying program that allowed each participant to respond on computers from any location. Both veteran and civilian participants recorded the interactions and feelings they recalled experiencing in the classroom during the month prior to participating in the study. The surveys administered were the Needs Threat Scale, the Numeric Rating Scale (NRS-11), the Wong Baker Faces Pain Rating Scale, the Interpersonal Needs Questionnaire (INQ), the Student Faculty Engagement (SFE) scale, the Community Based Activities (CBA) scale, and the Transformational Opportunity (TLO) scale along with a demographics questionnaire. Results show that participants in the veteran group reported greater thwarted belongingness than civilian students. Military service was also associated with less engagement in CBAs and TLOs. The association with less engagement in CBAs explained the impact of militarily service on thwarted belongingness.

The Wechsler Memory Scale –iii is the newest version of a six-decade old neuropsychological inventory. Since its conception, the Wechsler Memory Scale has been highly utilized by practitioners to accurately assess various memory functions in adult subjects. Revisions made within this inventory include the Faces I subtest, a facial recognition scale, which was added in order to strengthen the instrument’s accuracy at measuring episodic memory. Facial recognition, both cross-race and within-race, has been researched extensively and consistent biases have been found between race of test taker and cross-racial identification. Theories of exposure/contextual interaction (environment) and biological foundations have been the subject of study in the past in order to determine from where these racial identification deficits stem. The current study focuses on revealing bias in the Faces I subtest, regarding to an unequal distribution of racially representative faces in the testing materials. Eighty-eight college students were recruited to view forty-eight pictured faces from the Faces I subtest and determine the racial category to which the pictured face belonged. The subjects’ categorical responses were the basis for calculating a percent agreement score for racial category of each face. It was determined, using the results of subjects’ responses, that the Faces I subtest contained an unequal distribution of racially representative faces in both the Target and Interference testing material. This confirmed the presence of an inherent bias within the subscale. The implications of memory accuracy for the WMS-iii are discussed as it relates to different fields of study, but none more directly than the criminal justice system. Eyewitness testimony is a pivotal evidentiary tool in the criminal justice system, and ramifications of cross-racial identification deficits and biases in the tools to accurately assess memory are increasingly bringing this once heavily relied upon tool into question.
