### Non-family members

* TOY: Toy that speaks or sings

* EF\_: female experimenter (sometimes lab staff appear in the files when dropping off or picking up equipment), with inital (e.g. EFS)
* EM\_: male experimenter, with initial (e.g. EMM)
* BS\_: babysitter, first letter of first name

**Other speakers that are close to the family** (e.g. neighbors or family friends) are coded with the following formula:

* A or C (adult or child)
* F or M (female or male)
* First initial
  * e.g. AFH

When determining if a speaker was adult or child, coders were asked to make their best guess according to the speaker's tone of voice.
