Current Preregistrations

1. WFR - Word-Form Recognition: Headturn Preference Paradigm. Infants hear familiar word forms (mommy, diaper, bottle) and unfamiliar word forms (shammy, dapper, gottle). Infants are expected to prefer looking in the direction of the familiar word forms, and their ability to distinguish familiar and unfamiliar wordforms (and prefer the familiar ones) is expected to increase with age.

2. PREFUNC - Examines whether and how much infants use function words to anticipate nouns. The function word 'the' will be swapped in target sentences with the words 'do' and 'po'. Using a looking-while-listening task, times until infants look at target word will be measured. Infants are expected to improve in the looking-while-listening task with age, and will take longer to look at altered sentences ('do' and 'po') than unaltered ones. infants' noun comprehension will be more disrupted by altered function words with age.

3. PBS - Novel word learning in infants aged 14-22 months. Infants will be read a book containing three novel words (blick, dax, and shang) twice a day for a week. At the end of the period infants will perform two lab comprehension tasks:

   1. Familiar word comprehension - looking-while-listening task with a prompt "Look at the X!" measuring the proportion of the time infants spend looking at the object.

   2. Word learning choice - infants will be presented with a tray with cells and objects, and prompted to select an object by reaching for it, with the experiment measuring the accuracy of infants' responses.
