Query Element Name Data Type Size Required Description Value Range Notes Aliases
subjectkey GUID Required The NDAR Global Unique Identifier (GUID) for research subject NDAR* nimhid
src_subject_id String 20 Required Subject ID how it's defined in lab/project ptid
interview_date Date Required Date on which the interview/genetic test/sampling/imaging/biospecimen was completed. MM/DD/YYYY testdate
interview_age Integer Required Age in months at the time of the interview/test/sampling/imaging. 0 :: 1260 Age is rounded to chronological month. If the research participant is 15-days-old at time of interview, the appropriate value would be 0 months. If the participant is 16-days-old, the value would be 1 month. age
sex String 20 Required Sex of subject at birth M;F; O; NR M = Male; F = Female; O=Other; NR = Not reported gender
Query cong Integer Recommended Congruent Response Mapping trial Or Not. In congruent trials the cue is not necessary for proper response (i.e. regardless of cue, you respond the same direction).
correctresponse String 50 Recommended what was the correct response
Query csi Integer Recommended Cue stimulus interval.
cue String 10 Recommended Cue Type (letter or word). Switches between Letter or word for each cue type to account for Logan and Bundeson argument about cue-response mapping.
proceduretrial String 20 Recommended Trial type
task_stimulus String 10 Recommended One of Four Pictures. Red Circle, Green Circle, Red Triangle, or Green Triangle
Query ts_switch Integer Recommended Switch Task type From Previous Trial
Query ts_task Integer Recommended Current Task Type (shape or color)
subject_response String 10 Recommended Subject's response stimresp
Query acc Float Recommended Accuracy stimacc
Query rt Float Recommended Reaction Time stimrt
Query ts_costshort Float Recommended Switch Cost Short Cue interval (Correct trials only). Derived variable. Cost is measured for switch trials minus repeat trials of task (either respond to color or shape). Primary indicator of task switching.
Query ts_costlong Float Recommended Switch Cost Long Cue interval (Correct trials only). Derived variable. Cost is measured for switch trials minus repeat trials of task (either respond to color or shape). Indicator of 'residual' task switching when subjects have ample time to prepare for the switch.
Query ts_interference Float Recommended Interference (Correct trials only). Derived variable. Measured by comparing incongruent trials minus congruent trials. Congruency is determined by whether the cue is necessary to determine button response (i.e. is there response competition between color and shape ). Indicator of response competition or response inhibition
Query ts_accuracy Float Recommended Overall Accuracy across all conditions.
Query ts_shortcongnoswrt Float Recommended Short Cue interval, congruent, no switch trial mean reaction time. Intermediate derived variable across trials for conditions noted that is needed to determine RT difference indicators above.
Query ts_longcongnoswrt Float Recommended Long Cue interval, congruent, no switch trial mean reaction time. Intermediate derived variable across trials for conditions noted that is needed to determine RT difference indicators above.
Query ts_shortincongnoswrt Float Recommended Short Cue interval, incongruent, no switch trial mean reaction time. Intermediate derived variable across trials for conditions noted that is needed to determine RT difference indicators above.
Query ts_longincongnoswrt Float Recommended Long Cue interval, incongruent, no switch trial mean reaction time. Intermediate derived variable across trials for conditions noted that is needed to determine RT difference indicators above.
Query ts_shortcongswrt Float Recommended Short Cue interval, congruent, switch trial mean reaction time. Intermediate derived variable across trials for conditions noted that is needed to determine RT difference indicators above.
Query ts_longcongswrt Float Recommended Long Cue interval, congruent, switch trial mean reaction time. Intermediate derived variable across trials for conditions noted that is needed to determine RT difference indicators above.
Query ts_shortincongswrt Float Recommended Short Cue interval, incongruent, switch trial mean reaction time. Intermediate derived variable across trials for conditions noted that is needed to determine RT difference indicators above.
Query ts_longincongswrt Float Recommended Long Cue interval, incongruent, switch trial mean reaction time. Intermediate derived variable across trials for conditions noted that is needed to determine RT difference indicators above.

handedness String 29 Recommended handedness R;L;B;999 R = Right; L = Left; B = Both handed
stime String 20 Recommended Session time sessiontime
stimulus_type String 50 Recommended Stimulus set (e.g. "tones") stimulus
Query tfmri_nback_beh_switchflag Integer Recommended Box was switched 0;1 0= no switch; 1= switch switch
ncttsk String 250 Recommended Name of task. task
Query trial Integer Recommended Trial number 0::400; -777; -999 1 = first; 2= second; 3=third; 4=fourth; 5=fifth; 6=sixth; etc; -777=NA, -999=missing
Data Structure

This page displays the data structure defined for the measure identified in the title and structure short name. The table below displays a list of data elements in this structure (also called variables) and the following information:

  • Element Name: This is the standard element name
  • Data Type: Which type of data this element is, e.g. String, Float, File location.
  • Size: If applicable, the character limit of this element
  • Required: This column displays whether the element is Required for valid submissions, Recommended for valid submissions, Conditional on other elements, or Optional
  • Description: A basic description
  • Value Range: Which values can appear validly in this element (case sensitive for strings)
  • Notes: Expanded description or notes on coding of values
  • Aliases: A list of currently supported Aliases (alternate element names)
  • For valid elements with shared data, on the far left is a Filter button you can use to view a summary of shared data for that element and apply a query filter to your Cart based on selected value ranges

At the top of this page you can also:

  • Use the search bar to filter the elements displayed. This will not filter on the Size of Required columns
  • Download a copy of this definition in CSV format
  • Download a blank CSV submission template prepopulated with the correct structure header rows ready to fill with subject records and upload
