FAQ about NimStim:

 

1. Was this data compiled from studies with children as well as adults?

 

The card sorting task presented in the poster was collected with children as well as adults courtesy of Daniel Pine¹s laboratory at NIMH and BJ Casey¹s laboratory at the Sackler Institute of Cornell Medical School. This task validated the set as a whole. However, the labeling task (which provides individual numbers for each face) was performed with adults only (N = 70) courtesy of James Tanaka¹s laboratory at Oberlin College.  We are just about to complete data collection for test-retest reliability.  This manuscript is in preparation.

 

 

2. How did the participants rate the data?

 

Subjects were presented with labels, as well as the option ³unknown².

 

 

3. How were the pictures obtained?

 

Actors receiving their MA in Drama at NYU¹s Tisch Program were shown examples of facial expressions to get an idea of our aims & then asked to pose each facial expression. Muscles were adjusted until the desired expression was achieved.

 

 

4. What are the ethnicities of each model?

 

European-American:1, 2 ,5, 6, 7, 8, 9, 10, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36

Latino-American: 3, 37

African-American:11, 12, 13, 14, 38, 39, 40, 41, 42, 43

Asian-American:15, 16, 17, 18, 19, 45

 

5. Have these face expressions been validated?

 

Yes - validation data can be found in one spreadsheet which can be obtained by emailing us.

 

6. Some of the models look like people in the media.  Is that possible?

 

Yes – these models are professional actors and thus, might be recognized by subjects. For confidentiality reasons, we cannot reveal individual identities.  However, any time you find that subjects have a strong to any actor, you should consider removing that actor from your paradigm.

 

7. Some faces are not very good stimuli.

 

This is true.  All stimuli were included in this set so investigators can use the stimuli as they see fit.  Use the spreadsheet to guide your usage.

8. How should we reference the face set?

The MacArthur Foundation Research Network on Early Experience and Brain Development should be acknowledged in any manuscripts originating from projects using the NimStim stimulus set in the following manner:

"Development of the MacBrain Face Stimulus Set was overseen by Nim Tottenham and supported by the John D. and Catherine T. MacArthur Foundation Research Network on Early Experience and Brain Development. Please contact Nim Tottenham at tott0006@tc.umn.edu for more information concerning the stimulus
set.”

2 copies of manuscripts resulting from use of the NimStim face stimulus set should be sent to the Network at:
