Study example protocols

Headturn preference procedure - word segmentation (based on Jusczyk & Aslin, 1995) Download: | No protocol walkthrough available, but study structure is identical to !

• Training phase that requires accumulated looking time to each audio file

• Block design

• Randomized ordering of sides for lights/audio presentation

Headturn preference procedure - name recognition in noise (based on Newman 2009) Download: |

• Training phase that requires accumulated looking time to each audio file

• Block design

• Randomized ordering of sides for lights/audio presentation

Preferential looking - word recognition Download: |

• 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 for more on how these differ!

Preferential looking - fast-mapping Download: |

• 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: |

• 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: |

• 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: |

• 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

Conditioned Headturn - speech sound discrimination (based on Werker et al., 1981) Download: |

• 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: |

• 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
