Project Implicit Knowledge Base

This page will cover ways to integrate social media into your studies.  Right now the example will cover how to add a Facebook link with IAT feedback and a twitter link.  These are only recommended to be used on the final debriefing page, to avoid social network effects.  A sample demo task debriefing 2 is included below.

First off, make sure that your file is a .jsp, renaming the .html to .jsp if you need to.  Include the following at the top of the file:

<%@page import="java.util.*,java.net.*, org.uva.*" errorPage="/research/ShowError.jsp"%>

This page covers what you need to make data be encrypted before being sent to the database, as well as how to later decrypt the data.  You might want to do so in cases where the data you collect is confidential, especially if you are running measures on a demo study, since many people will access to the data.  There are several steps.

1.  Generate your encryption keys:

You can disable a study in the expt.xml file by adding the disable="URL" attribute to the study.  Anyone who tries to take the study will instead be sent to the URL that you specify.  Using this can be an advantage for private link studies, where you want people clicking the link after the study has ended to get a page telling them that the study is expired.  For example, to send someone trying to take your study to a more important study:

<Study id="Demo.Skin" datagroup="std" disable="http://humanoralien.com">

A new feature is ready for testing by lab members- a study progress bar.  This bar will appear at the top of the window as participants take the study, showing how much they have completed.  You can also set the weight of each task.  The weight will determine how much the bar will go up after the participant completes the task.  So if you have 100 total weight and the participant completes a 8 weight task, the progress bar will increase by 8%.  Just change your expt.xml file to use

<Task id="startpage">/common/en-us/html/InstructionsProgressBar.jsp</Task>

You can use the <Done> tag in your study expt.xml file to show that all important manipulations / measures have been completed by the participant.    Do so by adding <Done/> to the map, as follows:

<Map>

<Task id="startpage"/>

<Task id="iata"/>

<Done/>

<Task id="debriefing1"/>
<Task id="debriefing2"/>

</Map>

(1) Raw data from all Project Implicit DEMO, INTL, FEATURED TASK, PIMH, and ATTITUDES 1.0 and 2.0 datasets are available for use within Project Implicit labs (Nosek, Banaji, Greenwald, Teachman, Nock, Ratliff, Bar-Anan, Smith).  Any uses should be supervised by the PI of that laboratory.  PI's assume responsibility for communicating uses with each other to avoid conflicting uses.

The study Launch links can be long and sometimes mishandled by email. On production such web study links look like https://implicit.harvard.edu/implicit/Launch?study=/user/blah/blah.expt.xml (the research pool operates differently).

Take care not to add &refresh=true to the URL as that's only used during development. To create a more convenient form of this URL thats much shorter and easier to distribute, you can use link shortening services. The ones that I've used in the past include tinyurl.com, bit.ly, and goo.gl

This is a link that can track the status of research pool studies.  The link has a variable user parameter which is matched with all possible entries that contain the value assigned to the user.

For example: https://dw2.psyc.virginia.edu/implicit/research/data/details.jsp?user=at... should return all tasks in studies that have the word attitude in them.  To limit the number of matches, change the value of user to something more specific.

This attached zip contains all the files created during the afternoon flipper + spss segment.  The flipper part may be useful generally as it does not require installation of a statistics system.
