11. Pre- and post-dislocations in MICASE
In written English, the standard structure of a sentence is subject-verb-complement. However, in speech, variations are possible, and we actually move the subject into different positions. Example: “the test will be easy” (standard); “the test, it will be easy” (pre-dislocation); How common are the non-standard forms? Where do they occur, and why?

The phenomenon of pre- and post-dislocation is illustrated below:
Her little brother is really obnoxious. [standard sbject-verb-object (SVO)construction]
Her little brother, he’s really obnoxious. [pre-dislocation]
He’s really obnoxious, her little brother. [post-dislocation]
In a pre-dislocation, the noun phrase occurs first and is then picked up by an appropriate pronoun. In a post dislocation, the opposite occurs.
The first method we tried for finding dislocations in MICASE was to search in WordSmith Tools, a concordance software program. Using search terms such as “those *” with the pronoun (they, he, she, etc.) occurring within five words to the right, we were able to sift through the examples and find a preliminary list of dislocations. This method was useful because it helped us to identify several good examples, but it gave us very little indication of frequency. Additionally, in the above search we found only five dislocations in the 89 total examples that came up—a lot of effort for very few results.
So, using the results from the search as a guideline, we chose six transcripts in a variety of disciplines to analyze by hand: Public Math Colloquium, Academic Advising, Medical Anthropology Lecture, Intro Astronomy Discussion Section, Cognitive Psychology Research Lab, and Biology of Fishes. Of the 72,223 words total, we found 52 dislocations, which averages to about 700 dislocations per million words.
In our data, pre-dislocations were much more common than post-dislocations. Of the 52 total instances, there were only seven (13%) post-dislocations compared with 44 (85%) pre-dislocations. Here are some examples of the post-dislocations in our six transcripts:
1) yeah that’s what i was gonna say, dropout
2) you will have had more time to learn your minnows those of you who were um a little shaky last time
3) it should be, fairly simple, the lab exam
4) it was not a very easy thing to do getting those women out of there
Curiously, dislocations are not evenly distributed throughout the transcripts; rather, they occur in clusters. For example, in the 10-page Intro Astronomy Discussion Section transcript, eight of the nine dislocations occur in the first two pages:
These examples are full of deictics (“up here”) and demonstratives (“what do we call those?”), and are spoken by the instructor in order to elicit a response from the students. They are part of a series of questions checking the students’ understanding of vocabulary items, much as one might find in a language classroom. Example 9, which occurs outside of the cluster, follows neither the structural nor functional pattern of [1-8].
Now take a look at the 27-page Biology of Fishes transcript. The session took place on boats as students caught fish and recorded their measurements. Most of the conversation previous to the following excerpt took place within small groups and was very informal.
All four dislocations occurred in the last six pages, and in fact three of the four dislocations occurred in the span of six turns. The following extract appears near the end of the session, when the instructor gathers the class together to discuss their final examination.
S1: you will have okay, the exam will be in the same kind of format as uh, as as it was before, same number of pages the same kinds of material, um you will have had more time to learn your minnows those of you who were um a little shaky last time, um you will uh will be going back into to um, t- fine tune refine your keying and those kinds of things, the skills that you’ve acquired it should be, fairly simple the lab exam, we may have more questions on process such as what (gear) would you choose and why and those kinds of things. but it will be very similar to the one before.
SU-F: so we’re (keying out) two species we’ve never seen before right?
S1: yes
SU-F: wait two species we’ve never seen before?
S1: yes
SU-F: and how many that we have seen before do we have to key any of those out?
We can classify the dislocations into three broad (in fact sometimes overlapping) functional categories. In the first category, the speaker states the topic, or theme, of the utterance before offering a commentary.
1) um starting starting with epidemiologists they construct risk in a way that seems very solid
2) chemistry does that count as natural science?
3) so i’m just wondering like, Orgo, should i, take it this semester and then skip like you know
4) so these lines that run, north south what do we call those?
In the second category, the speaker breaks down a long or complex structure into pieces that are easier to keep track of (and for the listener as well).
5) that, those that linear stuff down here, you know this, regular growth rate here, um it’s not reaching an asymptote is it?
6) so you have the square packing, and the triangular packing, they both give about seventy-four percent of space filled
7) that’s how long it takes an anthropologist to analyze aggregate data with an N of forty it takes her a week
8) and the average of, four hundred, six-fifty and six-fifty, it would be like, five-something also
In the third category, the speaker begins to talk about something (the NP), and then adds information to further clarify the topic or set the background.
9) uh here’s Kepler’s book, he wrote a book after corresponding with Hariot for a while
10) a student of mine Sean McLaughlin, he’s an undergraduate here, he proved that his is the smallest possible box that you can build
11) you will have had more time to learn your minnows those of you who were um a little shaky last time
12) like they got into a fight and this friend, it was his friend’s like lover’s brother or something and so, he beat up his lover and the brother
The characteristics of pre- and post-dislocations outlined here serve as a strong starting point for future studies, but the results must be confirmed using a larger data set, with a wider variety of contexts. The description and analysis of dislocations and other less-commonly studied features of English can provide useful information to researchers and educators alike.

Do MICASE speakers prefer to say “the data is” or “the data are”? Or is it more complicated than this? This small study explores such questions.
The traditional rule recommends “between” for two things and “among” for more than two. Do MICASE speakers follow this rule? What are some of the variables involved?
In ordinary speech, hyperbole (or exaggeration) is common, as in “I’ve got a million emails to sort out”. What happens in academic speech? Do we still find these exaggerations (which we would not find in academic writing)? Or are MICASE speakers more careful? Find out in this Kibbitzer.
Do MICASE speakers use “less” with uncountables (e.g. less money) and “fewer” with countables (e.g. fewer dollars)? Or are there other factors at play?
Do people use the verb “suggest” to make suggestions, or other kinds of language? This kibbitzer provides some surprising answers to this question.
When do we say will and when do we shorten it to the contracted form ’ll? This careful quantitative study attempts to answer this question. (Amazingly, the first author was a first-term undergraduate when she did this project.)
The expression “no way” is often used among friends to express strong denial (“can you lend me fifty dollars? No way!”). In academic speech, is it used for some other purposes?
When we speak, we sometimes recognize that we have misspoken in some way, and so we try again. At times, we ‘announce’ that we are going to rephrase. What are the common ways of doing this in MICASE? And are these rephrasings typically longer or shorter than the originals? This kibbitzer attempts to answer these and similar questions.
These very similar pronouns play an important role in instructor-student interaction. When are they used in the full question form (“does anyone wanna guess?”), or when in a shortened structure (“anyone wanna guess?").
The use of “so” in such phrases as “I guess so” is not that common in MICASE. With which verbs does it occur? In which speech-events? Do other languages use a similar structure?
In written English, the standard structure of a sentence is subject-verb-complement. However, in speech, variations are possible, and we actually move the subject into different positions. Example: “the test will be easy” (standard); “the test, it will be easy” (pre-dislocation); How common are the non-standard forms? Where do they occur, and why?
Vocatives, such as “okay, John, let’s move on”, are known to be hard to explain to English learners. This study investigates the following kinds of question. What types of vocatives are there in MICASE? Which kinds of speech-event tends to attract vocatives? Do vocatives have different functions when they occur at the beginning, in the middle, or at the end of utterances?
This phrasal verb is one of the five most common in MICASE. Why is this? What are its functions? Does it have some special uses in academic speech? And what about the uses of “end up with”?
This Kibbitzer investigates the phrases that English speakers use to check for audience or listener comprehension, like “do you see what I’m saying?” or “does that make sense?”. Which phrases are most common?
This Kibbitzer examines the phrases that speakers use to end a list of examples that they do not wish to say in full (ex: “and so on and so forth”, “etcetera etcetera”, “and things like that”). What are the most common phrases in MICASE, and who uses them more frequently, instructors or students?
This Kibbitzer focuses on clarifactory phrases beginning “just so”. Why are these phrases useful for presenters and instructors?
Does the frequency of we vary across different academic disciplines and registers? In this kibbitzer, we examine MICASE samples from the physical sciences and compare our results with earlier studies.
