In Person: Cognition - Similarities
JCOGSIM Cognition - Similarities Module OVERVIEW The Cognition - Similarities Module, which was first administered during the 1993 collection wave and replicated in 2004, assesses cognitive ability using selected questions from the fourteen-item Weschler Adult Intelligence Scale (WAIS). WAIS items, which prompt participants to provide reasonable explanations for how two things are alike, adhere to the format, "in what way are [object #1] and [object #2] alike?" Eight items were asked of all participants in 1993, with between six and nine being administered in 2004 depending on random sub-sampling. For the 2011 collection wave, only the six WAIS items asked of all participants in 1993 and 2004 were included in the Cognition - Similarities Module; as in past waves, the simplest WAIS items were excluded pursuant to the assumption that the general ability of the WLS graduate cohort is high enough to make substantial variation in responses to simple items unlikely. The six included WAIS items called for participants to look for similarities between the things in the following sets: an orange and a banana; an eye and an ear; an egg and a seed; a table and a chair; a fly and a tree; and praise and punishment. If the participant permitted their interviewer to record the CAPI interview, responses to WAIS items were transcribed verbatim after its completion. If, on the other hand, the participant refused permission to record, their responses to WAIS items were manually entered by the interviewer during administration of the Cognition - Similarities Module. For each item, the participant's similarity response was assigned a score between zero and two quantifying its reasonableness, with a "2" being the top score. If the participant indicated they did not know how two things were alike when asked a WAIS item - or simply made no specific guess - they were assigned a value of "-1" for that item, signifying "don't know." If our audio record's quality was not sufficient for deciphering the participant's response to an item, or if the participant misheard the question and was not corrected by the interviewer, they were assigned a value of "-4" and coded as "not ascertained." A six-item summary of the participant's performance in the Cognition - Similarities Module was generated by totaling their scores for each WAIS item, codes of "don't know" being treated as scores of "0"; items coded as "refused" (-3) or "not ascertained" (-4) did not contribute at all to the summary measure. For more information about the nature of the Cognition - Similarities Module and our cognition data at prior collection waves, please see Appendix G; CORs 859 and 871, which outline the scoring and open-ended coding procedures used in 2004 (and 2011). Additionally, examples of 2-point, 1-point, and 0-point answers to each of the WAIS items can be found in cor970. No new documentation about the Cognition - Similarities Module was added to the appendix for the 2011 collection wave.
