Project Description

The WLS is a large-scale, long-term, longitudinal study of a random sample of men and women who graduated from Wisconsin high schools in 1957. Data on these participants were collected five more times through 2011. The data here are a small subset of tasks from the 2004 (sometimes labeled as 2003) and 2011 testing that are relevant to the other language tasks used in DementiaBank corpora. The large majority of these participants would be considered healthy controls.

Media and Transcript Database contents:

The WLS media folder contains the following folders and subfolders:

• Each folder contains audio files of cookie theft picture descriptions from 2011 testing
• Folders are organized in groups based on participant ID numbers
• Example: folder 00 contains participant ID numbers 00007, 00032; folder 12 contains ID numbers 12003, 12011.

The WLS Download transcripts folder contains CHAT transcripts of cookie the theft picture descriptions done at the 2011 testing.

Demographic data and test scores for these participants are available here.

• The first tab of the spreadsheet has data from 2004 and 2011 (see list below).
• The second tab has information about the variables and codes from 2004 and 2011.
• The third tab has the participant list with a subset of the data: age, years of education, and scores on the category fluency task at the 2011 test date. The last column shows which participants scored 1 standard deviation below the means reported for cognitively intact individuals (Tombaugh, Kozak, & Rees, 1999) on the category fluency task (see Guo, Li, Roan, Pakhomov, & Cohen, 2021).
• The fourth tab has data from the 2020 test date with sex, age, 10 variables related to diagnosis of cognitive status (e.g., level of impairment, consensus for Alzheimer's disease), and letter fluency task score.
• The fifth tab has information about the 2020 cognitive status variables.
