We report on the expanded database (ASL-LEX 2.0) that contains 2,723 ASL signs. For each sign, ASL-LEX now includes a more detailed phonological description, phonological density and complexity measures, frequency ratings (from deaf signers), iconicity ratings (from hearing non-signers and deaf signers), transparency (\u201cguessability\u201d) ratings (from non-signers), sign and videoclip durations, lexical class, and more. We document the steps used to create ASL-LEX 2.0 and describe the distributional characteristics for sign properties across the lexicon and examine the relationships among lexical and phonological properties of signs. Correlation analyses revealed that frequent signs were less iconic and phonologically simpler than infrequent signs and iconic signs tended to be phonologically simpler than less iconic signs. The complete ASL-LEX dataset and supplementary materials are available at https:\/\/osf.io\/zpha4\/ and an interactive visualization of the entire lexicon can be accessed on the ASL-LEX page: http:\/\/asl-lex.org\/.<\/jats:p>","DOI":"10.1093\/deafed\/enaa038","type":"journal-article","created":{"date-parts":[[2021,2,10]],"date-time":"2021-02-10T04:05:43Z","timestamp":1612929943000},"page":"263-277","source":"Crossref","is-referenced-by-count":92,"title":["The ASL-LEX 2.0 Project: A Database of Lexical and Phonological Properties for 2,723 Signs in American Sign Language"],"prefix":"10.1093","volume":"26","author":[{"given":"Zed Sevcikova","family":"Sehyr","sequence":"first","affiliation":[{"name":"San Diego State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naomi","family":"Caselli","sequence":"additional","affiliation":[{"name":"Boston University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ariel M","family":"Cohen-Goldberg","sequence":"additional","affiliation":[{"name":"Tufts University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen","family":"Emmorey","sequence":"additional","affiliation":[{"name":"San Diego State University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,2,18]]},"reference":[{"issue":"2","key":"2021031915534279400_ref1","doi-asserted-by":"publisher","first-page":"83","DOI":"10.1093\/deafed\/7.2.83","article-title":"The MacArthur communicative development inventory: Normative data for American sign language","volume":"7","author":"Anderson","year":"2002","journal-title":"Journal of Deaf Studies and Deaf Education"},{"issue":"1\u20133","key":"2021031915534279400_ref2","doi-asserted-by":"publisher","first-page":"19","DOI":"10.1016\/0024-3841(95)00031-3","article-title":"On the relation between ease of articulation and frequency of occurrence of handshapes in two sign languages","volume":"98","author":"Ann","year":"1996","journal-title":"Lingua"},{"key":"2021031915534279400_ref3","doi-asserted-by":"publisher","first-page":"340","DOI":"10.1037\/\/0096-1523.10.3.340","article-title":"Are lexical decisions agood measure of lexical access?
