	abstract = {This user guide describes how measures designed to test quantitative reasoning, verbal reasoning and verbal fluency were implemented in the 2010 and 2012 waves of the Health and Retirement Study. The Number Series test and Retrieval Fluency test were administered in the 2010 and 2012 waves of HRS to the full sample. The Verbal Analogies test was administered to a 10 percent random sample of the full HRS sample in 2012. Number Series measures quantitative reasoning, a specific type of fluid cognitive ability or fluid intelligence. Quantitative reasoning ability involves reasoning with concepts that depend upon mathematical relationships. The number series task requires the respondent to look at a series of numbers with a number missing from the series. The respondent must determine the numerical pattern and then provide the missing number in the series.  Retrieval Fluency measures an aspect of long-term retrieval : fluency of retrieval from stored knowledge. It was first incorporated in the HRS in the 2010 wave . This test is a typical neuropsychology test and was adapted by McArdle and Woodcock from the WJ-III Tests of Achievement: Retrieval Fluency ( Riverside Publishing). The measure consisted of a single item in which respondents were asked to name as many animals as they could within a 60-second time limit. This measure is consistent with animal fluency measures commonly administered in other neuropsychological exams (e.g., the CERAD animal fluency measure; Morris et al., 1989) . Administration protocols, test scoring, and data quality review procedures are discussed for each measure.},
