Reddit dataset RoBERTa (populism and emotions) computational linguistics
by David Abadi 05 Jun '24

Dear colleagues, Herewith, I’d like to share some news with researchers interested in populism, emotions, framing, media bias and social identity. Last year, Agneta Fischer and I collaborated with colleagues from Institute for Logic, Language and Computation (ILLC) at UvA (Pere-Lluís Huguet-Cabot, Verna Dankers, Ekaterina Shutova), and recently we published two papers in the field of computational linguistics (as listed below). For our latest paper, we developed a novel deep learning NLP model based on RoBERTa (Liu, 2019) to detect populist attitudes, media bias, emotions and social identity. In the near future, our dataset (consisting of 6861 annotated Reddit comments) will be made publicly available through GitHub for the research community to be used. Huguet Cabot, P. L.

Hi everyone, This Friday (June 25) from 14:30 - 16:00 we will have a very special meeting since we will have 4 students from the masters Brain & Cognition (UvA) and Neuroscience (VU) present their projects with the Hot Politics lab. The students have been designing and conducting an EEG pilot study this last semester, see more information below. Note this meeting start 30 min earlier, so at 2.30 pm (CET). The talks will be followed by a Q&A, and everybody is welcome to join via Zoom: https://uva-live.zoom.us/j/96492065253<https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fuva-live.…>. This meeting is already the last meeting of this semester! In the meantime, you can obviously enjoy our rich archive with talks by people like: Yanna Krupnikov (Stonybrook, link<https://www.youtube.com/watch?v=FcKp7E7oiPY>), Ursula Hess (Humboldt University, link<https://youtu.be/8mbXCXo6cvM>), Constantine Boussalis (Trinity College Dublin, link<https://youtu.be/CDxaFMS35jI>), Leor Zmigrod (University of Cambridge, link<https://youtu.be/GSUik0fO26M>), Michael Bruter (London School of Economics, link<https://youtu.be/M0bOxxTnWjU>) and Gerben van Kleef (University of Amsterdam, link<https://youtu.be/SuXVN2suwPE>). Check out the complete archive here<http://www.hotpolitics.eu/lab-meetings-archive/>. Measuring Neural Responses to Politics with EEG: In this project, we investigate emotional and cognitive biases drive political information-processing and decision-making. We are interested in the neural manifestations (using EEG measurement) of such biases among individuals with different political preferences and background. Examining this will give us more understanding of how people process politically-related information and make relevant decisions. The project consists of three separate studies, which will each be presented this Friday at the Hot Politics lab meeting: 1. "Mirror neuron activity in response to in- vs out-party politicians: an EEG pilot study" - by Karlijn Hendriks (Neuroscience, VU) 2. "Are we averse to ambitious leaders? ERP correlates in Ultimatum Game" - by Xinyao Zhang (Brain & Cognition, UvA) 3. "Drawing distorted conclusions: EEG correlates of the ideological mind" - by Babke Weenk and Christian Ramelow (Brain & Cognition, UvA) Post-doctoral Fellow Opportunity in Political Science: For those interested, the Centre for the Politics of Feelings , a partnership between the School of Advanced Study, University of London and Royal Holloway, University of London, is hiring a Post-doctoral Fellow with background in quantitative Political Science. The Fellow will have the opportunity to develop an innovative and interdisciplinary research project that in the field of emotions and politics. See the application here: Post-doctoral Fellow in Political Science (politics-of-feelings.com)<https://www.politics-of-feelings.com/post/post-doctoral-fellow-in-political…>. Looking forward to "seeing" you all Friday!

Hi everyone, This Friday (June 18) from 15:00 - 16:00 there will be another exciting lab meeting. In this session of the Online Hot Politics Lab, Gijs Schumacher (University of Amsterdam) will give a talk titled "Doing psychophysiology research in political science". This is joint work with Bert Bakker, Matthijs Rooduijn, Maaike Homan, Neil Fasching. See the abstract of his talk below. The talk will be followed by a Q&A, and everybody is welcome to join via Zoom: https://uva-live.zoom.us/j/96492065253<https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fuva-live.…> at 3pm (CET). Abstract: Facial electromyography (fEMG) is a type of a psychophysiological measurement that can register immediate positive and negative affective responses to experimental treatments. There is a clear benefit in registering affective responses while participants undergo a treatment, and at the same time fEMG can tap into the unconscious aspects of affective responses. As such, they offer clear benefits to the more popular survey questions that are used to measure affective responses to stimuli. However, fEMG is rarely used in political science because of formidable difficulties in processing, analyzing and interpreting this data. This paper addresses these issues by pooling 5 independent data collections, with in total 585 participants, 98 unique treatments and approximately 400,000 seconds of unique fEMG responses. We propose a scheme of how to process data, which addresses the heterogeneity of fEMG responses. We offer a way of analyzing fEMG data, that is particularly beneficial for the political science context in which we are unlikely to find large effects. By processing large amounts of treatment characteristics and respondent characteristics we also offer a range of benchmarks of useful comparison categories and guidance for new treatment design. Additionally, these analyses offer new perspectives on how "hot" politics is and for whom specifically. Have a great rest of the week and hope to "see" you all Friday!

Hi everyone, This Friday (June 11) from 15:00 - 16:00 there will be another exciting lab meeting. In this session of the Online Hot Politics Lab, Bert Bakker (University of Amsterdam) will give a talk titled "Reassessing the relationship between personality and political preferences". See the abstract of his talk below. The talk will be followed by a Q&A, and everybody is welcome to join via Zoom: https://uva-live.zoom.us/j/96492065253<https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fuva-live.…> at 3pm (CET). Abstract: Research on personality and political preferences generally assumes unidirectional causal influence of the former on the latter. However, there are reasons to believe that citizens might adopt what they perceive as politically congruent psychological attributes, or at least be motivated to view themselves as having these attributes. We test this hypothesis in a series of studies. Results of preregistered panel analyses in three countries suggest reciprocal causal influences between self-reported personality traits and political preferences. In two two-wave survey experiments, a subtle political prime at the beginning of a survey resulted in self-reported personality traits that were more aligned with political preferences gauged in a previous assessment. We discuss how concurrent assessment within the context of a political survey might overestimate the causal influence of personality traits on political preferences, and how political polarization might be exacerbated by political opponents adopting different personality characteristics or self-perceptions thereof. Have a great rest of the week and hope to "see" you all Friday!
