         NOTE: This variable is the log-transformed and log-normalized time to complete
         Trails B, and is equal to 1-log(T_B )/log(300) , where {B}$ is the number of
         seconds needed to complete the Trails B task, and 300 is the ceiling on the
         number of seconds allowed to complete the task. The resulting score is 0 when
         the participant took 300 seconds to complete the task (or did not complete the
         task in 300 seconds and was assigned a score of 300), and 1 when the task was
         completed in 0 seconds (unsurprisingly, we do not observe scores of 1). The
         direction of this log transformed score is such that higher scores (approaching
         1) are better and indicate faster performance. Values on the source variable not
         between 0 and 300 are treated as missing. Note that the reverse transformation
         is 300 (1-B) where $ is the log transformed, log-normalized complement number of
         seconds to complete the Trails B task.

VDEXF7                        HRS NUMBER SERIES (HRS HCAP VARIABLE SET 6)
         Section: A     Level: Respondent      Type: Numeric    Width: 3   Decimals: 0

         NOTE: According to the 2016 Harmonized Cognitive Assessment Protocol (HCAP)
         Study Protocol Summary, this item was developed for the HRS, this section
         evaluates Respondents ability for numeric reasoning by presenting a series of 6
         individual series of numbers, where one or two numbers in the series is missing.
         The Respondent is asked to take as much time as s/he needs, with the help of
         scrap paper and a pencil, to identify the missing number/s. This test is a
         block-adaptive test. Respondents are given a set of three number series
         questions of varying difficulty to first complete. Based on the number of
         correct responses in this first set of three (score Range = 0 to 4), Respondents
         are then assigned to a second set of three questions, for which the difficulty
         level is based on the number correct on the first set. The HRS uses two versions
         of the Number Series questions and respondents are assigned to the version that
         was not done in the previous wave. For HRS-HCAP, Respondents were assigned to
         the Number Series that was not assigned in the 2016 Core interview. If a
         Respondent was not able to do the Number Series section in the 2016 Core
         interview (not able to do practice questions, was too confused), then they were
         skipped out of this section. In creating vdexf7, missing codes (codes 996 and
         higher) on the source variable h1rnsscore are treated as missing.

         Section: A     Level: Respondent      Type: Numeric    Width: 2   Decimals: 0

         NOTE: Simply a renaming of h1rsdmscore. No accommodation for missing or other
         non-response codes has been used. Note that according to the 2016 Harmonized
         Cognitive Assessment Protocol (HCAP) Study Protocol Summary, the SDMT score is
         the number of correct pairings minus any mistakes or skips. This will create
         logical dependency or local dependence with SDMT errors (in executive function
         domain).

VDASP2                        TRAILS A (HRS HCAP VARIABLE SET 6)
         Section: A     Level: Respondent      Type: Numeric    Width: 14  Decimals: 10

         NOTE: This variable is the log-transformed and log-normalized time to complete
         Trails A, and is equal to 1-log(T_A )/log(300) , where {A}$ is the number of
         seconds needed to complete the Trails A task, and 300 is the ceiling on the
         number of seconds allowed to complete the task. The resulting score is 0 when
         the participant took 300 seconds to complete the task (or did not complete the
         task in 300 seconds and was assigned a score of 300), and 1 when the task was
         completed in 0 seconds (unsurprisingly, we do not observe scores of 1). The
         direction of this log transformed score is such that higher scores (approaching
         1) are better and indicate faster performance. Missing codes (i.e., not between
         0 and 300 on the source variables) are treated as missing.

         recored with five correct/incorrect indicators. Only correct responses are
         summed (code 1 on source variables). At least 1 of the five indicators must have
         a non-missing code (not missing or 96, 97, 98, 99) to get the 0-5 score on
         vdasp3.

         Study Protocol Summary this test assesses speed and attention and is derived
         from the Backward Count measure in the MIDUS Study. Respondents are asked to
         begin at 100 and to count backwards as fast as possible. They are given 30
         seconds and the number they reach and number of errors are recorded.

         NOTE: According to the 2016 Harmonized Cognitive Assessment Protocol (HCAP)
         Study Protocol Summary this test has been included in ELSA and assesses
         attention and speed. Respondents are given a paper with a large grid of letters
         and are asked to scan the grid as quickly as possible in a minute and to cross
         out as many P and W letters as they can in that time. This variable vdasp5 is a

         crossed-out letters.
