New subject: Request for data: Verbal descriptions and identification data

13 Oct 2020

Dear all,

I am working with Professor Colin Tredoux to analyse verbal or written
descriptions of perpetrators / faces and statements; unfortunately, we do
not have enough diversity in the descriptions that we have collected so
far. Specifically, our sample sizes are comparatively small compared to
studies that have used MTurk, and when we have found other researchers’
data on OSF (e.g., the Alogna et al replication of the VOE study), our
dataset is overwhelming tinted with descriptions of the ‘same’ perpetrator
(i.e., the moustached bank robber in the original video used of Schooler).
For these reasons, we are reaching out to other researchers for help. We
often collect witness statements in our experiments as part of our
laboratory procedure (encode – recall – recognise), but we do not normally
analyse these statement data. We are hoping that other researchers follow a
similar procedure and have description/statement data available.  We’d like
to ask if you would be willing to share your data where you have collected
descriptions of the perpetrator/s or statements of the coding event, and
also have corresponding lineup identification data.
The data does not need to be processed – we can process it on our side and
recode the variables (and I can send this back to you). To do this, we just
need to know stimuli characteristics (e.g., tp/ta, position of
suspect/target, confidence scale, lineup choice made etc).
Please let me know if you are able to assist us. Apologies again for the
random e-mail, but any assistance would be much assisted.
Thanks again! Hope to hear from you.
Kind regards,
Alicia Nortje and Colin Tredoux
