I'm a postdoctoral scholar in the Linguistics Department at Universität Potsdam, conducting research with the guidance of Adamantios Gafos. I'm originally from the UK, but I began studying internationally at the Universidad Complutense on my year abroad in Madrid while I was an undergraduate at Girton College, Cambridge, studying Modern Languages and Linguistics. I completed my MA in Linguistics with Dani Byrd in the Linguistics Department at the University of Southern California, before transferring to the University of Connecticut to complete my PhD under the supervision of Carol Fowler, with collaboration from Jim Magnuson.
While I have broad interests in the fields of Language and Cognition, my research is centred on Phonetics. I study speech production, speech perception and the relation between these two processes.
Complex dynamical systems provide a means for understanding and characterizing of coordination across a vast and varied array of disciplines. These systems change over time, consist of many coupled elements and yield higher-level patterns that would not be expected on the basis of their individual elements. This approach has been applied to explain patterns of general motor control (Turvey, 1990), as well as in the context of speech articulation (Browman & Goldstein, 1988), perception (Tuller, Jantzen & Virsa, 2008) and phonological structure (Gafos & Benus, 2006). I am interested in using dynamical concepts and explicit models of dynamical systems to predict patterns of change in language, in particular, patterns of phonetic accommodation among the phones of interlocutors of a single language (Nielsen, 2011; Pardo, 2006) and among the phones of multilinguals' languages (Sancier & Fowler, 1997; Bullock & Toribio, 2009), also referred to as phonetic drift.
In one line of research in which I am currently engaged, I ask how bilinguals' varying exposure to, and use of, each of their languages affects their phonetic categories. Interestingly, a speaker-hearer's use of one language can influence phonetic categories in their other language (Sancier & Fowler, 1997). However, it appears that this is not always the case (Tobin, Nam & Fowler, under review), as a variety of other linguistic and social factors influence the extent of accommodation (Giles, Coupland & Coupland, 1991). So far we have recruited Spanish-English and Korean-English bilinguals, and we are considering further language pairings.
The coarticulation resistance (CR) of a speech segment refers to the extent to which it inhibits coarticulation between the surrounding segments. Segments that require fine motor control or are realized with the tongue blade or tip, such as [ɹ], [s] and [z], are typically high in CR. Segments that only require gross motor control or are realized with the lips, such as [b] or [v], are typically low in CR. In an eyetracking study, we have shown that listeners are able to distinguish information-rich from information-poor patterns of coarticulation. They systematically look at orthographic words that are consistent with anticipatory coarticulation in a spoken sentence more quickly in the context of a consonant that is low in CR than in the context of a consonant that is high in CR (Tobin, Cho, Jennett & Magnuson, 2010).

For students to successfully learn, the classroom atmosphere must be such that all students feel free to share their thoughts and ideas, irrespective of their background. In my own experience, I performed best in the classrooms where my opinions were valued. While feedback from the teacher is important, respect amongst students is equally important. As a teacher, I see it as my responsibility to establish and promote an atmosphere of respect in the classroom. In the first few classes its is very important to allow time to get to know one’s students and to let them get to know each other, and every class should be an event that students look forward to and enjoy. Making the effort to develop this environment pays off for the teacher as much as for the students – what better class to teach than a class of enthused students, enjoying the material?
As a teacher, I see my role as a facilitator or enabler. I cannot learn for the students but I can endeavor to enthuse and encourage them to learn actively themselves. While traditional lecture-style teaching has its place, e.g. for auditory learners, students take more from the classroom when they are actively engaged in learning. Activities that require students to get up, move around, talk to each other and participate in experiments are the bread and butter of my classes. The activities they participate in are the activities of experimental psychologists.
To acquire the skill set of a good experimental psychologist, students must be able to come up with research questions that interest them and are of interest to their peers and they must be able to frame those questions scientifically. Allowing students an element of choice in the topics they choose for their assignments gives them the freedom to develop their own interests. In the initial stages of the assignment I encourage students to write down ideas that interest them and summarize papers that catch their eye. This is not graded, rather it gives students the opportunity to think things out, reflect on their ideas, and demonstrate their knowledge. Having them give peer- and teacher-graded presentations of drafts of their assignments first in small groups and later to the whole class allows them to ascertain the level of interest among their classroom community.
Technical skills, such as statistical testing, are an important part of scientific literacy. Specific skills like these merit some time. Students must be able to describe the statistical concepts involved and must be able to run the appropriate analyses. I use frequent graded and ungraded quizzes and interactive activities to ensure that students can explain these concepts and divide the learning up into demonstrations, ungraded in-class assignments and graded take-home assignments. In class students can follow the logic of the analysis as I demonstrate and clear up any technical problems they may have with their peers or with me. This is particularly important for students not familiar with the software being used or with IT in general. The take-home assignment ensures that each student is able to analyze data independently. This is the skill they will ultimately take away from the class.
I believe technology has a place in the classroom but that it should be used with specific objectives. Apple Keynote is a great way to present data visualizations and movies demonstrating ideas and concepts, but excessive use of technology may divert students’ attention away from the topic of the class.
I want students to leave my class not simply knowing the material, but being able to explain what they know to others, apply what they know, write coherently and vibrantly about what they know and enjoy what they know.
If you're enrolling/enrolled in a class of mine, you'll find materials posted on Moodle.
