[Coggroup] "Mouse tracking" lecture & workshop with Professor Sara Incera, May 21/22
by Cognitive Research at McGill 23 Apr '19

23 Apr '19

Dear all - Professor Sara Incera (https://psychology.eku.edu/people/incera) will be visiting McGill (funded by the CRBLM) to give a lecture about her fascinating work that uses “mouse tracking” to study bilingual language processing, and the following day, to give a workshop on how to use “mouse tracking” for similar or other kinds of research. “Mouse tracking” is a useful tool for studying cognitive processes that has received less attention than other standard techniques - e.g., button-press reaction time measures. Thus, knowledge of this technique could open new research opportunities/measures using standard computer equipment (i.e., an external mouse). Below are the 2 CRBLM events scheduled RE Professor Incera’s visit - 1) her research lecture, and 2) a workshop to show people how to conduct “mouse tracking” experiments using open source software. Please join us for both, and register ASAP for the workshop! Please pass this note along to others who may be interested.. —— 1) LECTURE: PROFESSOR SARA INCERA (PSYCHOLOGY, EASTERN KENTUCKY UNIVERSITY) http://crblm.ca/sara-incera-psychology-eastern-kentucky-university/ Title: The timing of the cognitive processes underlying bilingualism and the perception of foreign accents: Evidence from mouse tracking The mouse-tracking paradigm allows researchers to better understand how cognitive processes unfold over time by recording participants’ responses using a computer mouse. In this talk, I will present a diverse set of cognitive experiments in which I used the mouse- tracking paradigm for data collection. The goal is to provide attendees with different ideas of the types of data you can get using mouse tracking. I will discuss results from a number of different tasks including a lexical decision, a Stroop, and a rating task. I will cover the implications of methodological decisions like presenting two versus four response alternatives, or presenting a dichotomous (Word/Nonword) versus a continuous (Foreign—- Native) response option. In addition, I will briefly discuss how to interpret and analyze mouse-tracking data, including common pitfalls and best practices. I will cover the strengths and weaknesses of the method so attendees can get a sense of the types of research questions that can be answered using the mouse-tracking paradigm. In my opinion, triangulating across paradigms (eye tracking, mouse tracking, ERPs) is the gold standard to provide a full picture of the cognitive processes at play. Dr Sara Incera is an Assistant Professor in the Department of Psychology at Eastern Kentucky University. Her research interests include cognitive psychology, bilingualism, foreign accents, second language acquisition, and language development across the lifespan. When: Tuesday, May 21, 10:00am Where: room 461, 2001 McGill-College Coffee will be served before the talk. 2) MOUSE-TRACKING WORKSHOP WITH PROFESSOR SARA INCERA REGISTRATION: http://crblm.ca/mouse-tracking-workshop-with-sara-incera/ Title: Creating and analyzing mouse-tracking experiments The goal of this four-hour workshop is to create and analyze mouse-tracking experiments. During the first half of the workshop, participants will become familiar with the computer software MouseTracker. Each participant will work on creating a sample pilot study (4-6 stimuli) on a topic of their choosing. Participants will start from an example, choose the stimuli type, set up their trials, and make it look good using the “Designer” feature in MouseTracker. In addition, participants will be taught how to export their data (“Analyzer”) including considerations about conditions, restrictions, types of data (raw vs. normalized), and remapping. In the second half of the workshop, participants will learn to analyze mouse-tracking data using R (and R Studio). The mouse-tracking paradigm generates many dependent variables, so it is important to know which one to use for a specific research question. Participants will be introduced to data transformations (wide vs. long format – reshape2), data visualizations (mouse trajectories on a line graph – ggplot2), and, if there is time, data analyses (mixed models – lme4). The goal is to get participants to experience the whole process, from creating the experiment to interpreting the results, so they can use the mouse-tracking paradigm on their own whenever they are designing their next experiment. When: May 22, 2019, 9am-1pm Where: McGill Campus, Stewart Bio building, 1205 Dr Penfield Ave, S3/31

[Coggroup] CRAM - April 22 - Dr. Samuel Mehr
by Cognitive Research at McGill 08 Apr '19

08 Apr '19

Dear all, We are happy to announce the final CRAM (Cognitive Research at McGill) session this term on Friday, April 12th. Dr. Samuel Mehr is visiting from Harvard Psychology and will be speaking about universals in music perception and production (title and abstract below). Additionally, Dr. Mehr is happy to meet with any students and faculty who are interested in discussing research. He will be available this week Wednesday-Friday (April 10-12). If this is something that interests you, please reply to this email with your availability and we will try to arrange one-on-one or small group meetings. The talk will span from 12pm-1pm in room 735 of 2001 McGill College Avenue. All are welcome! Be sure to also check out Dr. Mehr's CIRMMT talk: https://www.cirmmt.org/activities/seminars/samuelmehr -- Dr. Samuel Mehr, Harvard Psychology Universals in music perception and music production Theories of the origins of music claim that the music faculty is shaped by the functional design of the human mind. On these ideas, musical behavior and musical structure are expected to exhibit species-wide regularities: music should be characterized by human universals. Many cognitive and evolutionary scientists intuitively accept this idea but no one has any good evidence for it. Most scholars of music, in contrast, intuitively accept the opposite position, citing the staggering diversity of the world's music as evidence that music is shaped mostly by culture. I will present two lines of work that attempt to resolve this debate, so as to lay out the basic facts of the human music faculty. The first line of work shows that the musical forms of songs in 86 cultures are shaped by their social functions (Mehr & Singh et al., 2018, Current Biology); in new work, this finding replicates in large samples of infants and of people who live in remote, small-scale societies. The second line of work applies tools of computational social science to the recently-created Natural History of Song corpora (http://naturalhistoryofsong.org) to demonstrate universals and dimensions of variation in musical behaviors and musical forms (Mehr et al., working paper, https://psyarxiv.com/emq8r). Our developing understanding of the basic architecture of music perception and music production lays the groundwork for building a comprehensive cognitive science of music. -- Warm regards, The CRAM Team (Mehrgol Tiv, Kevin da Silva Castanheira, Anna Mini Jos, & Azara Lalla) See our website for more information: https://www.mcgill.ca/psychology/events-colloquia-0/brownbag-series
