### Devices

* Looxcie: the little battery-powered camera that we use to see what the child is doing in Eyetracking. Previously these were worn by children in SEEDLingS to collect data.
* LENA: Small purple audio device worn for a whole day by the child (stands for Language Environment Analysis)
* Eyelink: our eyetracker
* Host computer: The computer that runs the eyetracker and records data. It runs a special version of Linux and can do nothing besides run the eyetracker.
* Display computer: The Windows computer that actually runs the experiment. It communicates with the host computer about when to record data. 

### Software/programs

* ELAN: a multipurpose media analysis program that we use to annotate VIHI audio files, encode looking in gaze-based experiments, and conduct reliability training for coders of discrimination studies, among other things
* Datavyu: the program we use to annotate SEEDLings videos (files end in .opf, or .csv if you're exporting)
* CLAN: the program we use to annotate SEEDLings audio (files end in .cex or .cha, or if you're exporting .xls)
* Vegas: the software that we import and sync the videos with (lives on Bergelson2014-2) (files end in .veg, or .mp4 if you're exporting)
* Audacity: the software we use to find silences in the audio file, and to process the audio stimuli (files end in .wav for audio files and .txt for silences)
* RStudio: statistics software, that uses the program R with a friendly interface, that can also manipulate data (files end in .r or .Rmd)
* python: a programming language that some of our automated tasks use (files end in .py)
* ruby: same as above (files end in .rb )
* java: same as above (files end in .ja)
* matlab: same as above (files end in .m)
* pfsx files: This file contains user- and document- specific settings like the font size used to display text. The \*.pfsx file can, however, be safely removed as it does not contain any annotation data (as opposed to the \*.eaf files).
* RPAD: A program through FileMaker Pro that contains data for participant recruitment purposes. Each study is listed, with specific participant requirements. With this data, the program will search for age-eligible candidates and provide their contact and demographic information. 

### Other terminology

* annotate: mark things, such as object words, utterance boundaries, utterance types, object presence, and speakers
* segment: to mark utterances in ELAN
* transcribe: word for word typing of what is said, either using a specific notation or standard orthography 
* datasource: the spreadsheet that the eyetracker uses to know which stimuli to show the child and in what order
* [MCDI: ](https://webcdi.stanford.edu/)vocabulary checklist parents' fill out (MacArthur-Bates Communicative Development Inventory). Also sometimes called the CDI.
* CHI: stands for target child in annotations. 
* PI: Private info (that needs to be scrubbed out of recordings).
* VI: visually impaired
* HI: hearing impaired
* TD: typically developing
