			SRECALL - Sibling Module		     cor943.txt

OVERVIEW

  The purpose of this module is to help provide a measure for the cognitive 
  ability of the respondent.  This module consists of two parts.  
  For the first part, the interviewer reads the following instructions 
  to the respondent:

  	"Part of this study is concerned with people's memory.  I'll read a set
  	of 10 words and ask you to recall as many as you can.  Please listen
  	carefully as I read the set of words. I'm not allowed to repeat any of
  	the words, so it's important that you can hear me very well.  When I
  	finish, I will ask you to recall aloud as many of the words as you can,
  	in any order.  Is this clear?  Ok.  The list is...".

  The interviewer then reads one of two lists of ten words, which appear one at
  a time on the interviewer's computer screen.  Once the interviewer finishes,
  the respondent repeats back as many words as he or she can remember and the
  interviewer records the repeated words.

  The second task occurs eight minutes later on average.  For the second task,
  the respondent is told:

  	"A little while ago, I read you a list of words and you repeated the
  	ones you could remember.  Please tell me any of the words that you
  	remember now."

  The respondent then recalls as many words as he or she can remember from the
  original list.  The purpose of these two tasks is to test the respondent's
  memory immediately after hearing something and then a short time later for
  comparison.

BRIEF VARIABLE DESCRIPTIONS

  ci401re		Indicates if sibling is in word recall 80% sample.

  ci402re		Creates 50% random sample to select word list 1 or 2
  			for sibling.

  ci403re - ci412re	Dichotomous variables for whether or not sibling
  			remembered each word on the list in immediate.

  ci413re		Number of correct words that sibling repeated in immediate.

  ci414re		Number of incorrect words that sibling said in immediate.

  ci416re		Amount of elapsed time between immediate and delayed.

  ci417re		Number of words sibling did recall in delayed and did not
  			recall in immediate.

  ci418re		Number of words sibling forgot from immediate to delayed.

  ci419re		Flag for review of immediate recall module.

  ci420re		Result of review of immediate recall module.

  ci421re - ci435re	Order of words that sibling recalled in immediate.

  ci447re - ci456re	Dichotomous variables for whether or not sibling remembered
  			each word on the list in delayed.

  ci457re		Number of correct words that sibling repeated in delayed.

  ci458re		Number of incorrect words that sibling said in delayed.

  ci459re		Flag for review of delayed recall module.

  ci460re		Result of review of delayed recall module.

  ci461re - ci475re	Order of words that sibling recalled in delayed.

CODING

  ci416re - ci418re & ci447re - ci475re

    Some respondents took a break in the interview after the immediate recall
    section, but before the delayed section.  These respondents, therefore,
    could not complete the delayed recall module, and so, received the code
    "MULTIPLE SESSIONS" (-15).

  ci421re - ci435re & ci461re - ci475re

    These variables receive a "DON'T KNOW/ TASK COMPLETE" (-1) response as soon
    as respondent stops recalling words.  Hence, -1s grow cumulatively
    throughout section until every respondent has finished.

NOTES

  Some respondents who refused the immediate recall task did not complete the
  delayed recall task due to partial interviews or multiple sessions.
  Therefore, the refusals for immediate are not all the same as the refusals
  for delayed.

  While the maximum number of answers a respondent is allowed to provide in the
  word recall tasks is twenty-six, all respondents completed the task in
  fifteen.  For this reason, only fifteen iterations are included rather than
  all twenty-six.

  During case review, coders noticed and corrected some instances in which the
  interviewer entered words in the wrong order.  Because coders cannot catch
  all instances of this error, users who are interested in word order might
  consider grouping the order variables into pairs to ensure maximum accuracy.

  Spoiled cases from review are likely to be biased toward high and low scores
  because most of the cases were reviewed due to strange scores.
