Experimental Recombination Paradigm

179 Shared Subjects

Experimental Recombination Paradigm (ERP): The ERP is a performance-based task used to assess prospection and episodic memory. For each trial, participants are asked to either recall a past or imagine a future event in response to personalized person-place-object cues in as much detail as possible. Participants are given 3 minutes per trial, and their audio-recorded event descriptions are coded for number of internal details (information about the central event described) and external details (information not directly relevant to the central event described, or general semantic information) provided. Reference: Addis DR, Pan L, Vu MA, Laiser N, Schacter DL. Constructive episodic simulation of the future and the past: Distinct subsystems of a core brain network mediate imagining and remembering. Neuropsychologia. 2009;47(11):2222-2238. doi:10.1016/j.neuropsychologia.2008.10.026. PMID: 19041331

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

Please email the The NDA Help Desk with any questions.
