<br>

At the end of every home visit (for each participant), you will upload the following:

1. **exactly 4 videos** (to your Databrary repository)
<br>&nbsp; - One-hour naturalistic play (include: decibel measure, shoes if child is wearing them in the house)
<br>&nbsp; - House walk-through (include: measurements of each room, sleeping arrangements, clothing, books, toys, shoes if child is barefoot)
<br>&nbsp; - 5-min structured play (focus on child and mom, even if they leave mat area)
<br>&nbsp; - Questionnaires (set up camera on tripod, focus on mom)
2. **exactly 1 decibel meter file** (to a Google Drive folder from the tablet)
3. **exactly 3 questionnaire files** (through the KoBo Toolbox app)
<br>&nbsp; - demographics questionnaire
<br>&nbsp; - home visit questionnaire
<br>&nbsp; - post-visit notes
<br>

## 1. Arrival introduction

_**Note**: Experimenters should always act in a professional and respectful manner when interacting with the participants and while in the home. Do not make comments or react to anything in front of the mom to make her feel uncomfortable. All families should feel that their participation in the study is meaningful._

Say: <say>Hi, my name is [NAME] and I’m visiting from [INSTITUTION]. Thanks for letting us come to your home today!</say>
<br> &emsp; &emsp; <say-es>Hola, mi nombre es [NAME] y vengo de [INSTITUTION]. ¡Gracias por recibirnos hoy en su hogar!</say-es>

- Ask if you should take your shoes off.
- Ask for good place (i.e. out of child’s reach) to put backpack and coat.
- Do not leave the tripod and other equipment lying around.
- Do not engage or warm up to the baby. Just need to make mom feel comfortable.

## 2. Consent to participate

Experimenter should explain the study and ask mom to sign the consent.

Say: <say>The visit has a few parts. I’ll begin by video-recording you and [CHILD] as you go about your day. I will video-record you both for one hour. Afterwards, I’ll ask you to give me a walk-through of your home that I will record on video to get a sense of the places [CHILD] goes and things that he/she plays with. I’ll also be measuring the dimensions of each room. Then, I will ask you and [CHILD] to play with some toys that I brought with me. Finally, I will ask you some general questions about your family and home, and about [CHILD]’s skills and routines. Everything will be video-recorded and the visit will last for no more than three hours. You will receive $50 for your participation at the end. Do you have any questions? Okay, great. Here is the consent form that explains everything I just said. Please read it through and then print and sign your name on the back.</say>
<br> &emsp; &emsp; <say-es>Esta visita tiene varias partes. Comenzaré grabándolos a usted y [CHILD] por una hora, mientras realizan sus actividades cotidianas. Después, le pediré que me dé un recorrido por su hogar mientras grabo los espacios, para tener una idea de los lugares donde él/ella va y las cosas con las que juega. También mediré las dimensiones de cada cuarto.  Luego, les pediré a usted y a [CHILD] que jueguen con unos juguetes que traje conmigo. Finalmente, le haré algunas preguntas generales acerca de su familia y su hogar, y sobre las habilidades y rutinas de [CHILD]. Todo será grabado en video y la visita no durará más de 3 horas. Por participar usted recibirá $50 al final de la visita. ¿Tiene alguna pregunta? ¡Muy bien! Aquí tiene el formulario de consentimiento que explica todo lo que le he dicho. Por favor léalo y luego en el reverso escriba su nombre y firme.</say-es>

## 3. One-hour natural play video & noise measurement  

### 3.1 Decibel Meter

Say: <say>We would like to measure the environmental noise levels. Is there a good place where I can put this measuring device where your child cannot reach? The tablet only measures the environmental noise levels and not what you’re actually saying.</say>
<br> &emsp; &emsp; <say-es>Queremos medir los niveles de ruido ambiental. ¿Hay algún lugar donde pueda colocar este dispositivo donde su hijo/a no lo pueda alcanzar? La tableta solo mide el ruido ambiental y no lo que usted está diciendo.</say-es>

- Set up tablet, put in microphone.
- Ensure that “Audio Tool” is force closed.
- Place device in the most central place in the home (e.g., living room).
- The microphone should be facing towards the room (e.g., away from walls) and propped up on the tablet case so that it is **not** lying flat against the surface of the space.
<br><br>

### 3.2 One-Hour Natural Play Video

General Recording Guidelines

-	Aim to get 60 minutes of uninterrupted natural play recoding, in addition to the time you take to give instructions, record the decibel meter and shoes. 
- Keep camera on the child at all times. Specifically, ensure that the child’s whole body is visible on camera. If mom is in frame, capture as much of her body as possible without compromising the view of the child.
- Record in front or to the side of the child as much as possible.
- Do not zoom in.
- Always try to stay toward the edge of rooms and doorways. You do not want to influence child to interact with you, or get in child’s way.
- Remain at as far a distance as possible (~3 to 5 m, hugging the wall) so that the child is not distracted by your presence.
- Try not to interact with the child or make eye contact with the child. Just watch through the viewfinder of the camera.
- If mom asks to pause the camera, ask for permission to point the camera away so you can continue recording audio. 

Say: <say>So I’m going to start recording now.</say>
<br> &emsp; &emsp; <say-es>Voy a empezar a grabar ahora.</say-es>

Begin recording and say: <say>For the next hour, do anything you would typically do as if I weren’t here. Try to ignore me as much as possible and I will stay out of the way. I will also try not to respond to you and [CHILD] so that he/she is not distracted. You can go anywhere in your home but we just ask you to remain indoors. You can play together or not, you can do chores, watch TV, talk on the phone, give him/her a bath or snack.  The idea is to capture what your typical day is like. And as a reminder, I’m just here to record so you will be in charge of [CHILD]’s safety.</say>
<br> &emsp; &emsp; <say-es>En la próxima hora, haga cualquier cosa que usted haría típicamente si yo no estuviera aquí. Intente ignorarme lo más posible y yo me mantendré fuera de su camino. También intentaré no responderle a usted o a [CHILD] para no distraerlo/la. Puede ir a cualquier lugar en su hogar, solo pedimos que se mantenga adentro. Pueden jugar juntos o no, puede hacer los quehaceres, ver televisión, hablar por teléfono, darle un baño o una merienda a [CHILD]. La idea es capturar su día típico. Le recuerdo que solo estoy aquí para grabar y usted está a cargo de la seguridad de [CHILD].</say-es>

After opening the app, quickly point the camera at the child and start timing for the one-hour natural play video. Note the time on the viewfinder of the camera and record for an additional 60 minutes.

*Note: The instructions and tablet set up should take no longer than 5-minutes.*

At the end of the one-hour recording, say: <say>Great, we are done with the one-hour recording!</say>  <say-es>¡Excelente, hemos terminado la grabación de una hora!</say-es>

With camera in hand (and still recording), walk over to where the tablet was placed, and hit the “save” button on “Audio Tool”.

##### Shoes

* If child was wearing shoes during the recording, say <say>Could I get a close-up of the shoes [CHILD] has been wearing?</say> <say-es>¿Puedo grabar más de cerca los zapatos que [CHILD] tiene puestos? </say-es>. Ask mom to remove the shoes, video-record the shoes after the session; take them off child and video the bottom, side, and top views. Focus the camera on the shoes and comment on shoe type, sole (hard, soft), heel (if any), and other observations.
* If the child was _not_ wearing shoes during the one-hour natural play video, record the shoes during the house walk-through.

</div>

Then stop video recording on the camera. Now that the camera is off, name the audio file with the site name and subject number (e.g. NYU_001) and close the “Audio Tool” app.

## 4. Video House Walk-through while measuring rooms

Start recording and say: <say>Now, we would like to see the space that [CHILD] gets to explore throughout the day. Please walk me through your home as I follow with a camera, and take measurements of the spaces. As we walk around, please show me where you keep any objects — toys, books, sippy cups, anything like that — that [CHILD] might interact with regularly. Please show me where you keep his/her clothes and shoes to give us an idea of the kinds of things he/she wears.</say>
<br> &emsp; &emsp; <say-es>Ahora nos gustaría ver el espacio que [CHILD] tiene para explorar durante el día. Por favor guíeme por su hogar mientras la sigo con una cámara y tomo medidas de los espacios. Mientras recorremos su hogar, por favor muéstreme donde guarda cualquier objeto- juguetes, libros, vasitos, cualquiera de las cosas con que [CHILD] interactúa regularmente. Por favor muéstreme donde guarda la ropa y los zapatos de él/ella para tener una idea de las cosas que él/ella viste.</say-es>

</div>

Ensure that all of experimenter's personal items, recording equipment, yoga mat and toys for structured play are stored out of sight.  

Video capture tips:  

- Watch recording through viewfinder to ensure that the view is not blurry or shaky  
- Move the camera slowly and walk slowly  
- A clear and steady view, free of blurriness and shakiness, is necessary for detailed coding of the home environment
- The laser measure device does not work against reflective surfaces (mirrors, glass walls, etc), so point to a non-reflective surface or measure from the reflective surface towards the opposite direction.

About room measurements:  

- You will measure all rooms in the house while you do the video walkthrough  
- A room is any space used by someone on a regular basis - bedrooms, kitchens, bathrooms, basements - they don't need to have windows  
- A room has to have a clear demarcation (e.g., a wall or an entry). A space is considered to be a room if it has a minimum of 3 walls.
- If the room has a short divider (e.g., when a kitchen and a living room are divided by a counter), count as one big room and measure accordingly.

Steps:  

1. Start at the entrance of the home.
2. Pause at the entrance of each room.
3. Audibly name the room by its function (e.g., <say>This is where [CHILD] sleeps</say>).
4. First, get as much of the **Entire Room** in frame as possible. Keep the camera zoomed out and make sure to capture the ceiling and the floor of the room.
5. Next, pan the camera SLOWLY from **Left to Right**.
6. Then, pan the camera to **Floor**, name the different types of surfaces in the space (hardwood, plush carpet, thin rug, linoleum, tile, etc.), and then pan to the **Ceiling**.
7. Ask parent if child spends time in each room: <say>Does [CHILD] spend any time in this room?</say> <say-es>¿[CHILD] pasa algo de tiempo en este cuarto?</say-es>
8. Ask parent about child’s objects in the room: <say>Do you keep anything for [CHILD] in this room? (If yes) Would you mind showing me?</say> <say-es>¿Guarda algo para [CHILD] en este cuarto? (If yes) ¿Me lo puede mostarar por favor?</say-es>
9. **Ensure during the house walkthrough that the parent provides information on all of the following:**
    - *Children's Sleeping Arrangements.* <say>Please show me where [CHILD] typically sleeps.</say> <say-es>Por favor muéstreme donde [CHILD] duerme típicamente.</say-es>
    - *Child’s Clothes.* <say>Please show me where you keep [CHILD]’s clothes.</say> <say-es>Por favor muéstreme donde guarda la ropa de [CHILD].</say-es>
    - *Child’s Shoes.* <say>Please show me where you keep [CHILD]’s shoes.</say> <say-es>Por favor muéstreme donde guarda los zapatos de [CHILD].</say-es>
    - *Child’s Books.* <say>Please show me where you keep [CHILD]’s books.</say> <say-es>Por favor muéstreme donde guarda los libros de [CHILD].</say-es>
    - *Child’s Toys.* <say>Please show me where you keep [CHILD]’s toys.</say> <say-es>Por favor muéstreme donde guarda los juguetes de [CHILD].</say-es>
10. Film the **Location** of the storage space (drawer, toy chest, cabinet) in clear context of the rest of the room. Then, SLOWLY and CLEARLY film the **Contents** of the storage space to show what is inside of it, zooming in if needed. (Overhead view for bed, crib, drawers, toy chest, etc.; Zoomed in side view for cabinet, closet, bookshelf, etc.)
11. Hold the camera in one hand while you take measurements of the room using the other. <br>
    - Turn measure on by pressing ON/DIST button. Make sure the laser beam is visible. <br> 
    - Measure wall to wall, lengthwise and widthwise. <br>
    - If a room has an odd or asymmetrical shape (i.e., any shape other than a rectangle or a square), measure the largest rectangle or square area of the room. <br>
    - Place the base of the laser flat on the wall, push ON/DIST againt to send the beam across the room (avoid moldings, door castings, reflective surfaces) <br>
    - Repeat the above for the second dimension (length or width) <br>
    - Focus camera on laser measure for each measure and read numbers out loud with units (e.g. <say>eight point five feet</say>) <br>
12. Do ** *NOT* ** turn off the camera when walking to next room.
13. Walk SLOWLY.
14. When all rooms are recorded, walk back to the entrance of the home and then stop recording.

Say: <say>Now I would like you to play with your child for about 5 minutes with these toys. We always clean these toys before and after each visit. I have a mat that I’m going to ask you to sit on. Where’s a good place for me to put it?</say>
<br> &emsp; &emsp; <say-es>Ahora le pediré que por favor juegue con su hijo/a durante unos 5 minutos con estos juguetes. Siempre limpiamos los juguetes antes y después de cada visita. Tengo una estera/alfombra en la cual le voy a pedir que se siente. ¿Dónde es un buen lugar para ponerla?</say-es>

Place the mat on a clearing on the floor.

Start recording and say: <say>Please sit next to [CHILD] on this mat. I’ll give you a set of toys. Please play with [CHILD] however you like for 5 minutes.</say>
<br> &emsp; &emsp; <say-es>Por favor siéntese al lado de [CHILD] en esta estera/alfombra. Le daré unos juguetes. Por favor juegue con [CHILD] por 5 minutos como usted quiera.</say-es>

* If the child is playing with a different toy before the recording, ask mom if she can put the toy away.
* Hand tote bag with toys to mom. Quickly point the camera at the child and mom and note the time on the viewfinder. Record for an additional 5 minutes.
* Record so that the child and mother’s entire bodies - faces, eyes, and hands - are captured. If child stands up, make sure to capture the feet. If you are in a position from which you cannot capture the full face and both eyes, position yourself to capture a profile view.
* If child and mom are separated at any point, focus camera on child.
* Use timer on camera to time engagement.
* After 5 minutes, say “Great job! We can now move on to the questionnaires.”
* If the child is still playing with the toys after 5 minutes, let the child play and continue on to the questionnaires.
