 At this age the verbal learning and timed letter search tasks used at age 43 years (nos. 1 and 4 above) were re-administered, although the latter used only one trial.  In addition, a delayed recall condition was added to the verbal learning task, using an interval of approximately 90 seconds.  Tests 2, 3 and 5 above were not re-administered at 53 years.  However, four new tests were given at this age: At this age the verbal learning and timed letter search tasks used at age 43 years (nos. 1 and 4 above) were re-administered, although the latter used only one trial.  In addition, a delayed recall condition was added to the verbal learning task, using an interval of approximately 90 seconds.  Tests 2, 3 and 5 above were not re-administered at 53 years.  However, four new tests were given at this age:
  
-  - **The National Adult Reading Test** (ART; Nelson & Willisson, 1991).  This is a pronunciation test involving 50 irregular words of increasing difficulty, chosen to violate conventional grapheme-phoneme correspondence rules.  To pronounce any of the words correctly the respondent must therefore be able to recognize them in their written form rather than rely on intelligent guesswork.  Thus it is effectively a test of knowledge acquisition, although it correlates with full-scale IQ. \\  **N.B.** the ART is traditionally scored for errors, as it is here, but this can easily be inverted by subtracting the score from 50, so as to be consistent with the direction of the other cognitive test scores.+  - **The National Adult Reading Test** (NART; Nelson & Willisson, 1991).  This is a pronunciation test involving 50 irregular words of increasing difficulty, chosen to violate conventional grapheme-phoneme correspondence rules.  To pronounce any of the words correctly the respondent must therefore be able to recognize them in their written form rather than rely on intelligent guesswork.  Thus it is effectively a test of knowledge acquisition, although it correlates with full-scale IQ. \\  **N.B.** the NART is traditionally scored for errors, as it is here, but this can easily be inverted by subtracting the score from 50, so as to be consistent with the direction of the other cognitive test scores.
   - **Verbal fluency**  Category fluency was assessed by asking survey members to name as many different animals as possible in one minute.  The score is the total number of animals named, allowing anything belonging to the animal kingdom (from amoeba to humans), but not counting repetitions, redundancies (e.g. brown cow, spotted cow) or proper names (e.g. Rover, Kitty).   - **Verbal fluency**  Category fluency was assessed by asking survey members to name as many different animals as possible in one minute.  The score is the total number of animals named, allowing anything belonging to the animal kingdom (from amoeba to humans), but not counting repetitions, redundancies (e.g. brown cow, spotted cow) or proper names (e.g. Rover, Kitty).
   - **Prospective memory** (sometimes referred to as 'remembering to remember').  Survey members were informed that, at a later stage of the interview, they would be given an envelope and asked to write a name and address on it, and that, on receipt of the envelope, they were to remember to turn it over, seal it, and write their initials on it.  For the outcome variable a full score of 3 was achieved if both actions were completed without prompting; 2 if one action was achieved without prompting; and 0 if no action was undertaken without a prompt.   - **Prospective memory** (sometimes referred to as 'remembering to remember').  Survey members were informed that, at a later stage of the interview, they would be given an envelope and asked to write a name and address on it, and that, on receipt of the envelope, they were to remember to turn it over, seal it, and write their initials on it.  For the outcome variable a full score of 3 was achieved if both actions were completed without prompting; 2 if one action was achieved without prompting; and 0 if no action was undertaken without a prompt.
