“…[23][24][25][26][27] Dalton and Richardson analyzed responses to the Broken Window picture description task from the AphasiaBank discourse protocol. 7 They created a core lexicon (CoreLex) list of the 24 unique lemmas (word roots, such as "run" for "runs," "running" and "ran") used by at least 50% of the normative sample (92 control participants). When transcripts from 235 PWAs were analyzed to see how many of those 24 CoreLex words were used in their picture descriptions, results revealed significant differences between PWAs and controls as well as between all aphasia subtypes.…”

“…When transcripts from 235 PWAs were analyzed to see how many of those 24 CoreLex words were used in their picture descriptions, results revealed significant differences between PWAs and controls as well as between all aphasia subtypes. CoreLex lists are also available for the Cat Rescue and Refused Umbrella tasks, 7 and will soon be available for the Cinderella story. Again, these materials can be found at the Discourse Analysis link on the AphasiaBank website.…”

“…Here, we will focus on new, clinically relevant discourse measurement tools and teaching resources that have been added to the AphasiaBank website (https://aphasia.talkbank.org/) over the ensuing years. The new measurement tools include Main Concept (MC) checklists, [3][4][5][6] Core Lexicon Checklists, 7,8 Correct Information Unit (CIU) computation, 9 the SCRIPT command for analyzing fixed scripts, 10,11 a larger EVAL reference database, and advanced tools to compute measures from the Quantitative Production Analysis (QPA) 12,13 and Northwestern Narrative Language Analysis (NNLA) [14][15][16] systems. The teaching resources include an online aphasia tutorial, a set of videos highlighting examples of behaviors typically seen in the connected speech of people with aphasia (PWAs), group treatment videos, classroom activities, tutorial screencasts, and conference poster archives.…”

AphasiaBank is a shared, multimedia database for the study of communication in aphasia. This article describes a variety of discourse measurement tools and teaching resources available at the AphasiaBank website. The discourse measurement tools include main concept analysis, core lexicon checklists, correct information unit computation techniques, and other automated analyses using the CLAN program. These tools can be used to measure a variety of aspects of language production for assessment as well as treatment evaluation and clinical research purposes. Importantly, they are intended to help make the discourse analysis process more efficient and reliable. Teaching resources include an online tutorial on aphasia, videos of typical behaviors seen in aphasia, group treatment videos, classroom activities, tutorial screencasts, and conference posters. These resources can be used for a variety of clinical and educational purposes. The AphasiaBank website is part of the larger TalkBank project which provides many other shared databases and resources that are relevant to professionals interested in communication and communication disorders.

“…Dalton and Richardson measured informativeness in discourse by analyzing CoreLex and main concepts (MCs) in transcripts from 166 controls and 235 PWA doing one of the Apha-siaBank picture description tasks (Broken Window). 9 Stems (or lemmas) produced by 50% or more of the controls were included in the CoreLex. Results indicated that PWA had significantly lower CoreLex scores and MCs than controls.…”

AphasiaBank has used a standardized protocol to collect narrative, procedural, personal, and descriptive discourse from 290 persons with aphasia, as well as 190 control participants. These data have been transcribed in the Codes for the Human Analysis of Transcripts (CHAT) format for analysis by the Computerized Language Analysis (CLAN) programs. Here, we review results from 45 studies based on these data that investigate aphasic productions in terms of these eight areas: discourse, grammar, lexicon, gesture, fluency, syndrome classification, social factors, and treatment effects. For each area, we also indicate how use of the CLAN programs has facilitated the analysis. We conclude with an examination of ways in which the size of the database could be increased through on-site recordings and data from teletherapy.

“…4 Indeed, research examining CoreLex indicates that PWAs produce fewer typical lexical items than controls. [5][6][7][8] CoreLex has demonstrated sensitivity to age-related differences in neurologically healthy individuals, 9 between healthy individuals and PWAs, and between aphasia subtypes. 7,8 CoreLex also correlated with performance on standardized assessments and other discourse measures.…”

A Compendium of Core Lexicon Checklists

Core Lexicon (CoreLex) is a relatively new approach assessing lexical use in discourse. CoreLex examines the specific lexical items used to tell a story, or how typical lexical items are compared with a normative sample. This method has great potential for clinical utilization because CoreLex measures are fast, easy to administer, and correlate with microlinguistic and macrolinguistic discourse measures. The purpose of this article is to provide clinicians with a centralized resource for currently available CoreLex checklists, including information regarding development, norms, and guidelines for use.
