Project description:A central assumption that underpins much of the discussion of the role played by social cognition in brain evolution is that social cognition is unusually cognitively demanding. This assumption has never been tested. Here, we use a task in which participants read stories and then answered questions about the stories in a behavioural experiment (39 participants) and an fMRI experiment (17 participants) to show that mentalising requires more time for responses than factual memory of a matched complexity and also that higher orders of mentalising are disproportionately more demanding and require the recruitment of more neurons in brain regions known to be associated with theory of mind, including insula, posterior STS, temporal pole and cerebellum. These results have significant implications both for models of brain function and for models of brain evolution.
Project description:This study aimed to scrutinize the effects of the reflection-based questioning approach (RBQA) on Myanmar students' achievement in English reading comprehension. The RBQA approach covers Oo et al.'s (2021) reflective teaching model for reading comprehension (based on planning, acting, reflecting, and evaluating) in which the teacher uses a questioning strategy (initiate-response-evaluate model). Employing cluster randomized trials, quasi-experimental research was conducted to investigate RBQA's effectiveness in teaching reading comprehension skills to Grade-9 students. The experimental group (N = 228) received the RBQA intervention; the control group (N = 230) did not receive the intervention but was provided with traditional instruction. During RBQA intervention, teachers used the anonymous student questionnaire and observation scheme as effective reflection tools. After a five-week intervention, both groups completed post-tests to assess their achievement. The study findings revealed that teaching with RBQA had a significant positive effect on students' reading comprehension. Therefore, this study is of immense significance to English language teachers and their students.
Project description:Troubleshooting is an important part of experimental research, but graduate students rarely receive formal training in this skill. In this article, we describe an initiative called Pipettes and Problem Solving that we developed to teach troubleshooting skills to graduate students at the University of Texas at Austin. An experienced researcher presents details of a hypothetical experiment that has produced unexpected results, and students have to propose new experiments that will help identify the source of the problem. We also provide slides and other resources that can be used to facilitate problem solving and teach troubleshooting skills at other institutions.
Project description:Anterior cingulate cortex (ACC) and striatum (STR) contain neurons encoding not only the expected values of actions, but also the value of stimulus features irrespective of actions. Values about stimulus features in ACC or STR might contribute to adaptive behavior by guiding fixational information sampling and biasing choices toward relevant objects, but they might also have indirect motivational functions by enabling subjects to estimate the value of putting effort into choosing objects. Here, we tested these possibilities by modulating neuronal activity in ACC and STR of nonhuman primates using transcranial ultrasound stimulation while subjects learned the relevance of objects in situations with varying motivational and cognitive demands. Motivational demand was indexed by varying gains and losses during learning, while cognitive demand was varied by increasing the uncertainty about which object features could be relevant during learning. We found that ultrasound stimulation of the ACC, but not the STR, reduced learning efficiency and prolonged information sampling when the task required averting losses and motivational demands were high. Reduced learning efficiency was particularly evident at higher cognitive demands and when subjects experienced loss of already attained tokens. These results suggest that the ACC supports flexible learning of feature values when loss experiences impose a motivational challenge and when uncertainty about the relevance of objects is high. Taken together, these findings provide causal evidence that the ACC facilitates resource allocation and improves visual information sampling during adaptive behavior.
Project description:Graduate programs in the biomedical sciences dedicate considerable resources to recruiting students from underrepresented racial and ethnic groups. However, students from these minoritized groups have decreased access to the 'hidden curriculum' that must be navigated in order to be successful in graduate school. Here, we describe a student-led initiative at Johns Hopkins University, the Hidden Curriculum Symposium, that is organized to help prepare new students from underrepresented groups for graduate school. Preliminary evidence from surveys suggests that the initiative does increase the preparedness of minoritized students, and we believe this approach could also prove useful at other academic institutions.
Project description:ImportanceFood insecurity on college campuses has emerged as an urgent public health priority; however, there has been a lack of studies focused on graduate students or postdoctoral trainees, particularly those enrolled at private academic institutions.ObjectiveTo estimate the prevalence of and factors associated with food insecurity among graduate students and postdoctoral trainees at a private academic university in Boston, Massachusetts.Design, setting, and participantsIn this cross-sectional survey study, a survey on food insecurity was sent to graduate students and postdoctoral trainees at 3 health-focused graduate schools at Harvard University during the end of the spring 2023 academic term (April to June). Participants were studying medicine, dental medicine, or public health. Data analysis was performed from July to September 2023.ExposureSociodemographic characteristics of graduate students and postdoctoral trainees.Main outcomes and measuresThe primary outcome was food insecurity as assessed using the US Household Food Security Survey Module. Food insecurity also encompassed low and very low food security. Bidirectional stepwise logistic regression models were conducted to estimate the factors associated with food insecurity for graduate students and postdoctoral trainees.ResultsThe analytic sample included 1745 participants (response rate, 55%): 1287 were graduate students and 458 were postdoctoral trainees. The median age of respondents was 29.0 (IQR, 7.0) years, and more than half (1073 [61.5%]) identified as female. A total of 694 respondents (39.8%) identified as Asian, 625 (35.8%) as White, and 426 (24.4%) as being of other race or ethnicity. The prevalence of food insecurity was 17.4% (224 of 1287) among graduate students and 12.7% (58 of 458) among postdoctoral trainees. Among graduate students, factors associated with food insecurity included being Asian (OR, 1.06 [95% CI, 1.01-1.11]) or of other race or ethnicity (OR, 1.07 [95% CI, 1.02-1.13]), receiving financial aid (OR, 1.09 [95% CI, 1.05-1.13]), and having housing instability (OR, 1.53 [95% CI, 1.45-1.61]). Among postdoctoral trainees, factors associated with food insecurity included receiving Supplemental Nutrition Assistance Program benefits (OR, 1.59 [95% CI, 1.28-1.97]), having housing instability (OR, 1.33 [95% CI, 1.22-1.45]), and not owning a car (OR, 1.11 [95% CI, 1.04-1.18]).Conclusions and relevanceIn this study, a substantial proportion of graduate students and postdoctoral trainees at a private academic institution experienced food insecurity during the academic year. These findings underscore the need for national and institutional interventions to address the complex, structural factors related to food insecurity in these distinct populations.
Project description:The ability of scientists to effectively communicate their research, and scientific ideas in general, with a variety of audiences is critical in both academic and non-academic careers. There is currently a dearth of formal and informal science communication training opportunities for graduate students in science, technology, engineering, and mathematics (STEM) fields. This curriculum paper introduces ComSciCon-Triangle, a graduate student-organized science communication workshop for graduate students in STEM at research universities in the Raleigh-Durham, North Carolina, region. Started in 2015, this annual workshop aims to empower graduate students to be more engaged in communicating their research with the public as well as with fellow scientists. Each workshop consists of interactive panel discussions with invited science communicators (science writers, academics, filmmakers, etc.), informal networking opportunities with invited guests and other attendees, and hands-on sessions for improving oral and written communication skills. Analyzing pre- and post-survey data from all ComSciCon-Triangle attendees from 2015 to 2017, we find that workshop attendees feel significantly more confident in their ability to communicate scientific ideas with both the general public and with other scientists, and more confident submitting a written piece to a popular science publication or journal. We discuss how ComSciCon-Triangle serves as a model for local science communication workshops "for graduate students, organized by graduate students."
Project description:Graduate students' academic misconduct has received increasing attention. Although past literature has emphasized university faculty as an important influencing factor on students' moral behaviors, the mechanisms must be further disclosed. We investigated how supervisors' ethical leadership influenced graduate students' attitudes toward academic misconduct. We explained why and how supervisor gender affects post-graduate students' social learning process by integrating social cognitive theory and role congruity theory. Study 1 used a sample of 301 graduate students in 60 academic teams in four Chinese business schools. Study 2 used experimental vignette methodology to enhance the findings' internal and external validity and provided evidence of causality. Based on the two complementary studies, we found that supervisors' ethical leadership significantly inhibited students' acceptance of academic misconduct through students' moral efficacy and the ethical climate of the academic team. The indirect effect via moral efficacy was more significant s for female supervisors. Implications for ethical leadership, academic misconduct, gender differences in leadership, and moral education were discussed.
Project description:ObjectiveThe purpose of this study was to understand the experiences of historically underrepresented graduate students, more than half of whom were enrolled in science, technology, engineering, and mathematics (STEM) disciplines, during the COVID-19 pandemic. This focus group study represents an initial stage in developing an intervention for historically underrepresented graduate students and their families.BackgroundUnderrepresentation of graduate students of color in STEM has been attributed to a myriad of factors, including a lack of support systems. Familial support is an endorsed reason for persisting in graduate school. It is unclear what historically underrepresented graduate students' experiences are during uncertain times, such as a pandemic.MethodFocus groups were conducted online using a videoconferencing platform during the COVID-19 pandemic. Five focus groups included: historically underrepresented doctoral students (n = 5), historically underrepresented master's students (n = 6), academic faculty (n = 7), administrator, administrative faculty, and academic faculty (n = 6), and families of historically underrepresented doctoral students (n = 6). Data were analyzed using thematic analysis.ResultsHistorically underrepresented graduate students experienced difficulties in accessing resources, adjustments to home and family life, amplification of existing nonfinancial issues, and expressed both fears of and hopes for the future.ConclusionThe COVID-19 pandemic exacerbated existing inequalities in access to resources as well as nonfinancial family support.ImplicationsThis study may help normalize historically underrepresented graduate students' experiences during the COVID-19 pandemic. The findings include ideas for informing families about graduate school that can enlighten family support efforts for historically underrepresented graduate students and their families.
Project description:The mental health crisis in graduate education combined with low treatment rates among engineering graduate students underscores the need for engineering graduate programs to provide effective methods to promote well-being. There is an extensive body of neuroscience research showing that contemplative practices, such as mindfulness, produce measurable effects on brain function and overall well-being. We hypothesized that a mindfulness-based training program designed for engineering graduate students would improve emotional well-being and, secondarily, enhance research capacity. An initial pilot study was conducted at a single institution (Phase 1), followed by a larger study conducted at both the original and a second institution (Phase 2) to gather additional data and show the program's transferability. The program comprised eight weekly mindfulness training sessions. Individuals in the study were randomly assigned to either an intervention group or wait-list control group. We administered pre- and post-test surveys with quantitative measures designed to assess emotional and physical well-being, as well as creativity, research satisfaction, and desire to contribute to the betterment of society. Participants also completed a summative survey to evaluate the impact of the program on their well-being and research. Analysis revealed statistically significant findings: improved emotional health, decreased neuroticism, increased positive affect, decreased negative affect, and increased mindfulness in the intervention groups compared to the control groups. Intervention groups in Phase 2 also reported statistically significant improvement in satisfaction with their research. Our findings suggest that mindfulness training has the potential to play a vital professional and personal development role in graduate engineering education.
