Discrimination of, or preference between, two language varieties, with results from various methods
Curator is Loretta Gasparini
Search Strategy:
Published studies (n = 25) and an unpublished dataset (n = 1) already known to the investigators were included. A Google Scholar search was conducted on 17th April 2020 using Harzing’s Publish or Perish Windows GUI Edition 7.19 software with the following keyword combination: {"infant" OR "infancy" OR "baby"} & {"language discrimination" OR "dialect discrimination" OR "accent discrimination" OR "rhythm class discrimination"}. This search yielded over 3000 records, the first 500 of which were considered, and three unique studies were retained after abstract and full text screening. To identify infant studies that focussed on durational metrics, another Google Scholar search was conducted on 17th April 2020 with the keyword combination: {"infant" OR "infancy" OR "baby"} & {"deltaC"} & {"rhythm"}. This search yielded 299 results, all of which were considered, but no unique eligible studies were identified. Calls for studies were posted on the following mailing lists on April 16th, 2020: ICIS listserv, cogdevsoc listserv and the CHILDES mailing list, and three eligible studies were identified. The reference lists of all included studies and one review on the topic (Nazzi & Ramus, 2003) were checked, revealing eight unique eligible studies. We requested recommendations for studies from corresponding authors of included studies who could be contacted, and two eligible studies were thus identified.
