Go for broke: The role of somatic states when asked to lose in the Iowa Gambling Task
Full text link© 2016 The Author(s) The Somatic Marker Hypothesis (SMH) posits that somatic states develop and guide advantageous decision making by “marking” disadvantageous options (i.e., arousal increases when poor options are considered). This assumption was tested using the standard Iowa Gambling Task (IGT) in which participants win/lose money by selecting among four decks of cards, and an alternative version, identical in both structure and payoffs, but with the aim changed to lose as much money as possible. This “lose” version of the IGT reverses which decks are advantageous/disadvantageous; and so reverses which decks should be marked by somatic responses – which we assessed via skin conductance (SC). Participants learned to pick advantageously in the original (Win) IGT and in the (new) Lose IGT. Using multilevel regression, some variability in anticipatory SC across blocks was found but no consistent effect of anticipatory SC on disadvantageous deck selections. Thus, while we successfully developed a new way to test the central claims of the SMH, we did not find consistent support for the SMH

Correction to Ashby and Rakow (2014):"Forgetting the Past: Individual Differences in Recency in Subjective Valuations From Experience", Journal of Experimental Psychology: Learning, Memory, and Cognition, (2014), Vol. 40, No. 4, pp. 1153-1162
No full textReports an error in "Forgetting the past: Individual differences in recency in subjective valuations from experience" by Nathaniel J. S. Ashby and Tim Rakow (Journal of Experimental Psychology: Learning, Memory, and Cognition, 2014[Jul], Vol 40[4], 1153-1162). There was an error in how the Akaike Information Criterion (AIC) were calculated with the punishment for parameters being subtracted rather than added. To correct for this error the SUMe models AIC scores reported in the tables (both individual, and group level M and Mdn.) should have 4 added to them, while the VUM and SWIM models AIC scores should have 8 added to them. Corrections to the results of Study 1, Study 2, and the second RT analysis are presented in the erratum. (The following abstract of the original article appeared in record 2014-12458-001.) Recent research investigating decisions from experience suggests that not all information is treated equally in the decision process, with more recently encountered information having a greater impact. We report 2 studies investigating how this differential treatment of sequentially encountered information affects subjective valuations of risky prospects when observations of past outcomes must be used to estimate the prospect’s payoff distribution, and examine how individual differences in cognitive capacities influence information usage. In Study 1 we found that a sliding window of information model that averages a subset of (only) the most recently encountered outcomes (samples) fit the subjective valuation data for a portion of individuals better than models that integrate all observed outcomes. This pattern of results is replicated in Study 2, in which we also found that the amount of information used to form valuations varies greatly between individuals, and that individual difference in memory span explains a portion of this variation. Combined, these results suggest a process in which information usage is in part reliant on cognitive capacity, and where information aggregation appears to be memory based rather than online, providing new insight into the processes involved in the construction of valuation in experiential decision

No full textTim Di Muzio on 'Sabotage'
No full textIn a series of essays published in 2013 and 2014 on capitaspower.com, political economist Tim Di Muzio explored the concept of ‘sabotage’ as it applies to capitalist power. I recently rediscovered these essays and was so impressed by them that I have reposted them here as a single piece.
About the author: Tim Di Muzio is a researcher at the University of Wollongong. He is the author of numerous books, including Debt as power, Carbon capitalism, and The 1% and the Rest of us

First person - Tim Petzold
Full text linkFirst Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping researchers promote themselves alongside their papers. Tim Petzold is first author on ‘ Connexin 41.8 governs timely haematopoietic stem and progenitor cell specification’, published in BiO. Tim conducted the research described in this article while a PhD student in Julien Bertrand's lab at the Department of Pathology and Immunology, Faculty of Medicine, University of Geneva, Switzerland. He is now a postdoc in the lab of Holger Gerhardt at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association, Berlin, Germany, investigating developmental biology – previously his focus was on how blood stem cells develop and now it has shifted to how the vascular system develops
