## Setup/demo protocols

[**Setup protocol**](https://drive.google.com/file/d/19RBiE0vnplcNItd8yC2CAG-2AVDVllEq/view?usp=sharing) (see [this page](/bittsy/set-up/bittsy-installation.md#running-the-setup-protocol) for more information on how to use this protocol)

## Study example protocols

{% hint style="warning" %}
**Before running any protocol you download or receive from a colleague:**\
1\. Change the [starting definitions](/bittsy/creating-protocols/starting-definitions.md) to match the locations/IDs of *your* displays/lights/speakers (see the page on [running the setup protocol](/bittsy/set-up/bittsy-installation.md#running-the-setup-protocol) to determine these)\
2\. Change file paths of all audio/image/video files to the correct location on your computer (see the page on [tags referencing files](/bittsy/creating-protocols/tags/tags-referencing-files.md) for more info)

No protocol walkthrough available, but study structure is identical to [**this one**](/bittsy/creating-protocols/example-protocols/headturn-preference-paradigm-example.md)!

* Several versions available of this protocol to demonstrate varying levels of randomization of trial order: 1) full randomization of a stimulus set, 2) presenting in a fixed order, 3) pseudo-randomization of trial order. See the [protocol walkthrough](/bittsy/creating-protocols/example-protocols/preferential-looking-example-word-recognition.md) for more on how these differ!

**Preferential looking - fast-mapping**\
**Download:** [Github](https://github.com/umdldev/BITTSy-Protocols/tree/master/PrefLook_CIWordLearning) | [Google Drive](https://drive.google.com/file/d/13TkM0ja4AAfvP9XM9Lz2Jzn0zmcBIeD3/view?usp=sharing)\
[**Protocol walkthrough here**](/bittsy/creating-protocols/example-protocols/preferential-looking-example-fast-mapping.md)

* Training phase of alternating word-object pairs
* Test phase with random assignment of object arrangement and random ordering of target words

**Habituation - familiarization to a category**\
**Download:** [Github](https://github.com/umdldev/BITTSy-Protocols/tree/master/Habit_categorylearning) | [Google Drive](https://drive.google.com/file/d/1tF5xl21hwmoYY2xAW0JU7Zey2tioq_oE/view?usp=sharing)\
[**Protocol walkthrough here**](/bittsy/creating-protocols/example-protocols/more-complex-habituation-category-learning-example.md)

* Pre-test, habituation, test, and post-test phases
* Habituated to a set of images; individual images chosen randomly without repetition
* Tested on novel image belonging to same category and novel image from a novel category

**Habituation - word-object pairings (based on Werker et al., 1998)**\
**Download:** [Github](https://github.com/umdldev/BITTSy-Protocols/tree/master/Habit_wordobjectpair) | [Google Drive](https://drive.google.com/file/d/1XVtg_DRGBzl20bslqjrXzoQqS2-a4YCF/view?usp=sharing)\
[**Protocol walkthrough here**](/bittsy/creating-protocols/example-protocols/simple-habituation-example.md)

* Pre-test, habituation, test, and post-test phases
* Random assignment to a single word-object pair for habituation
* Test phase consisting of all possible word-object pairs in random ordering

**Habituation - visual oddity paradigm**\
**Download:** [Github](https://github.com/umdldev/BITTSy-Protocols/tree/master/Habit_visual_oddity) | [Google Drive](https://drive.google.com/file/d/1_k7IvVciytjGE8imbAGjqTttkeQNK-0P/view?usp=sharing)

* Pre-test, habituation, dishabituation, and post-test phases
* Habituation is to a single visual stimulus
* Dishabituation phase consists of repeated exposures to the familiarized video and a novel video, with the novel video occurring more rarely than the familiarized video

* Training phase in which each trial has the "change" stimulus
* Test phase in which each trial plays the "change" or "control" stimulus
* Use of JUMP to present a reward stimulus when participant correctly detects the change stimulus

**Conditioned Headturn - signal detection in noise**\
**Download:** [Github](https://github.com/umdldev/BITTSy-Protocols) | [Google Drive](https://drive.google.com/file/d/1F-no2FkszWQO-rLj8WxUECGy_ARFkApc/view?usp=sharing)\
[**Protocol walkthrough here**](/bittsy/creating-protocols/example-protocols/conditioned-headturn-signal-detection.md)

* Continuous background noise
* Training phase in which each trial has the relevant signal (audio of a name being called)
* Conditioning phase in which participant must show anticipatory headturn three trials in a row to proceed to the test phase
* Test phase in which each trial either does or does not present the relevant signal
* Use of JUMP to present a reward stimulus when participant correctly detects the signal
