[Coggroup] Reminder, McGill Cognitive Area Seminar, March 24 2017: Dr. Jason Gullifer
by Anna Zamm 24 Mar '17

24 Mar '17

Dear all, This is a reminder that Dr. Jason Gullifer (Post-doc, Titone Lab, McGill Psychology) will be speaking in our Cognitive Area Seminar today, March 24th, 3:30 - 5 PM (Room S3/4, Stewart Biology Building, 1205 Docteur Penfield Avenue). His talk is titled, "How context of language usage influences bilingual language control." For a full abstract, see below the dashed line. Please join us at this event! ------------------------------------------------- How context of language usage influences bilingual language control Dr. Jason Gullifer, Post-doc, Department of Psychology, McGill University Knowledge and daily use of a second language are associated with neurocognitive consequences relative to monolingualism. For example, when proficient bilinguals read or speak in one language, they experience coactivation and competition from the unintended language. Neurally, the first and second language have been shown to rely on a shared network distributed across prefrontal, subcortical, and parietal brain areas. Given that the two languages are generally integrated in function and structure, an open question is how bilinguals manage cross-language influences and ultimately select the intended language from multiple coactivated alternatives. One class of theoretical perspectives (i.e., the lexical account) assumes that coactivation is resolved at the level of the lexicon, while another class (i.e., the cognitive account) assumes that bilinguals exploit more general set of mechanisms to differentiate the two languages, including application executive control abilities and exploitation of relevant social-contextual information. Here, I present data from two studies on proficient French-English bilinguals. The first study on eye-movements during reading suggests that contextual information drives bilingual lexical access. The second study uses resting state functional connectivity analysis and shows that repeated exposure to particular patterns of language usage influences functional organization of neural networks implicated in bilingual language control. Both findings are compatible with cognitive accounts of lexical selection.

[Coggroup] McGill Cognitive Area Seminar, Mar 17 2017: Timothy Dunn

Dear all, Timothy Dunn (PhD Candidate, University of Waterloo) will be speaking in our Cognitive Area Seminar this Friday, March 17th, 3:30 - 5 PM (Room S3/4, Stewart Biology Building, 1205 Docteur Penfield Avenue). His talk is titled: *"Determinants of effort: Error-likelihood strongly biases initial evaluations of effort."* For a full abstract, see below the dashed line. Please join us at this event! ---------------------------------- *Determinants of effort: Error-likelihood strongly biases initial evaluations of effort* Timothy Dunn, Department of Psychology, University of Waterloo Why are some actions evaluated as being effortful? We addressed this question by examining perceptions of effort when faced with a direct trade-off between how much time a task takes versus how error-prone it is. That is, do people prefer to engage in a task associated with low time demands but high error-likelihood, or a task associated with high time demands but low error-likelihood? We find that individuals perceive options that are high in error-likelihood and faster as more effortful than options that are low in error-likelihood and slower. Furthermore, when asked to evaluate which of two tasks was (a) more effortful, (b) more error-prone, and (c) more time consuming, effort-based and error-based choices closely tracked, though a similar association was not present for time-based choices. Last, the finding that high error-likelihood is closely tied to effort decisions was additionally demonstrated in free-choice contexts where experience with engaging in each of the tasks was afforded. Thus, in contrast to time-based accounts of effort, results are consistent with the likelihood of error commission driving effort-based choices. An *effort-as-errors *bias where individuals heuristically weigh the perceived likelihood of error commission will be proposed to account for the current results. This talk is based on a pre-print article available @ researchgate.net/profile/Tim_Dunn4

[Coggroup] Participants needed! Exploring touchless gesture interaction with consumer products
by Francesco Tordini 07 Mar '17

Hello, would it be possible to forward this message to the list? Thank you -- Francesco Tordini ► skype francesco.tordini PhD Candidate ► http://www.cim.mcgill.ca/sre/personnel/ Centre for Intelligent Machines and Department of Electrical and Computer Engineering McGill University 3480 University Street, Room 426 Montreal, QC, H3A 0E9, Canada | T: (514) 398 8201 _________________________________________________ Greetings, > The Centre for Interdisciplinary Research in Music Media and Technology (CIRMMT) at McGill is looking for English mother tongue, right-handed participants (who are familiar with smartphones) to participate in a study on gestural interaction with a distant object. This study aims to assess the natural gestural interaction between a participant and a loudspeaker with a sensor system, without touching it, or using a remote controller. The experiment will take around 1 hour and involves executing gestures with your dominant hand. > > You will be compensated $15 for your time. This work has been certified by the review ethics board and is conducted by Prof. Isabelle Cossette and Prof. Marcelo Wanderley and their team at the Schulich School of Music, McGill University. No risks are associated with this research. Your confidentiality will be protected. > > If you are interested, please contact gesturestudy.cirmmt(a)gmail.com [1], to schedule an appointment between March 10 and March 17, 2017. > > Thank you for your consideration, > > Francesco Links: ------ [1] mailto:gesturestudy.cirmmt@gmail.com
