Alpha-band Brain Dynamics and Temporal Processing: An Introduction to the Special Focus
No full textFor decades, the intriguing connection between the human alpha rhythm (an 8-to 13-Hz oscillation maximal over posterior cortex) and temporal processes in perception has furnished a rich landscape of proposals. The past decade, however, has seen a surge in interest in the topic, bringing new theoretical, analytic, and methodological developments alongside fresh controversies. This Special Focus on alpha-band dynamics and temporal processing provides an up-to-date snapshot of the playing field, with contributions from leading researchers in the field spanning original perspectives, new evidence, compre-hensive reviews and meta-analyses, as well as discussion of ongoing controversies and paths forward. We hope that the perspectives captured here will help catalyze future research and shape the pathways toward a theoretically grounded and mechanistic account of the link between alpha dynamics and temporal properties of perception
Alpha-Band Frequency and Temporal Windows in Perception: A Review and Living Meta-analysis of 27 Experiments (and Counting)
No full textTemporal windows in perception refer to windows of time within which distinct stimuli interact to influence perception. A simple example is two temporally proximal stimuli fusing into a single percept. It has long been hypothesized that the human alpha rhythm (an 8-to 13-Hz neural oscillation maximal over posterior cortex) is linked to temporal windows, with higher frequencies corresponding to shorter windows and finer-grained temporal resolution. This hypothesis has garnered support from studies demonstrating a correlation between individual differences in alpha-band frequency (IAF) and behavioral measures of temporal processing. However, nonsignificant effects have also been reported. Here, we review and meta-analyze 27 experiments correlating IAF with measures of visual and audiovisual temporal processing. Our results estimate the true correlation in the population to be between .39 and .53, a medium-to-large effect. The effect held when considering visual or audiovisual experiments separately, when examining different IAF estimation protocols (i.e., eyes open and eyes closed), and when using analysis choices that favor a null result. Our review shows that (1) effects have been internally and independently replicated, (2) several positive effects are based on larger sample sizes than the null effects, and (3) many reported null effects are actually in the direction predicted by the hypothesis. A free interactive web app was developed to allow users to replicate our meta-analysis and change or update the study selection at will, making this a “living” meta-analysis (randfxmeta.streamlit.app). We discuss possible factors underlying null reports, design recommendations, and open questions for future research

Jason vs GIJOE
No full textThesis (Master's)--University of Washington, 2019Jason vs GI JOE is partly an exercise in autobiography, an experiment in relational aesthetics, and an interdisciplinary artist project at the intersection of comic books, creative writing and performance art. This comic book, Jason vs. GIJOE, is a postmodern double erasure, based on the comic book GIJOE: Cobra II (Issue 1). The original pictures from the comic book have been removed, and replaced by a series of short narratives, describing autobiographical events from the life of the author: me, Jason. Speech bubbles from the original have been left to comment back over top of the stories, obscuring meaning but creating moments of unplanned dialogue. The comic is a readymade, twice erased: once to replace the drawings of the initial comic, and again when using the original dialogue bubbles to speak back to the narrative
Oral history interview with Jason Poudrier
No full textJason Poudrier, author, discusses growing up in a military family and living in Alaska, North Dakota, Oregon, and finally Oklahoma. He describes what it was like enlisting in the Army after high school in 2001 and how his military service affected him. A recipient of the Purple Heart, he shares his experiences getting injured by shrapnel in Iraq. He later talks about how he uses poetry and writing to cope with his memories of war, and how he hopes to help others do the same.The Deep Roots: Oklahoma Authors Collection is a series of interviews with authors who discuss their lives, work, and creative processes

The people behind the papers – Jason Ko and Daniel Lobo
No full textPlanarians grow when they are fed and shrink during periods of starvation. However, it is unclear how they maintain appropriate body proportions as their size changes. A new paper in Development investigates the differences between growth and shrinkage dynamics and builds a mathematical model to explore the mechanisms underpinning these two processes. To learn more about the story behind the paper, we caught up with first author, Jason Ko, and corresponding author, Daniel Lobo, Associate Professor at the University of Maryland.https://doi.org/10.1242/dev.20298
Ep. #085 - Jason W. Moore
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic talk capital and Vanilla Isis and then (11:21) we welcome to the podcast the one and only Jason W. Moore from Binghamton University, author of Capitalism in the Web of Life (Verso, 2015) and Anthropocene or Capitalocene? (PM Press, 2016). We chat with Jason about his most recent work, co-authored with Raj Patel, A History of the World in Seven Cheap Things (U California Press, 2017), forthcoming this October. We talk about why he wanted to write a book for a broader audience, the problems with the “anthropocene” concept in the human sciences, how “capitalocene” can improve our thinking about world history, and how we can avoid vulgar materialism in critical environmental research and activism today. We cover the role that states and agriculture have played in shaping modern capitalism and Jason calls for a seriously engaged pluralism to tackle the urgent challenges of our era. We discuss the cheapening or thingification of life, capitalism as a gravitational field, the importance of frontiers, the violence of the Great Domestication, and why if green energy remains in the mode of “cheap fuel” nothing will change about capitalist accumulation. Jason explains why racial and gender domination are so often lacunae in critiques of petromodernity. Finally we ruminate on how to unmake the capitalist world-ecology and the key principles of the “reparation ecology” that Jason and his colleagues are calling for. Tired of the debate within the left about whether to prioritize jobs or the environment? Then you’ll want to listen on
