Singmann, Kellen, & Klauer (2013) ORE Data

skk13.Rd

Data presented in Singmann, Kellen, & Klauer (2013) investigating the other race effect (ORE) using the unsure-extended 2-high threshold model. Participants perform a face recognition memory test for both own-race and other-race faces. The original analysis is performed using no-pooling maximum likelihood estimation and shows an effect of target race on the Dn parameter.

Usage

skk13

Format

skk13

A data frame with 8,400 rows and 7 variables:

id

Factor with 42 levels indicating the participant identifier.

trial

Factor indicating the trial number.

race

Factor indicating the race of the image shown, either german (own-race) or arabic (other-race).

type

Factor indicating the item type (i.e., MPT tree), either old (i.e., studied item) or new (i.e., non-studied item).

resp

Factor indicating the response, either old, unsure, or new.

rt

response time in seconds.

stim

Factor with 200 levels indicating the shown image/item.

Details

The original abstract is as follows: The other-race effect (ORE) refers to the phenomenon that recognition memory for other-race faces is worse than for own-race faces. We investigated whether White Germans exhibited an ORE towards Turkish or Arabic faces using a multinomial processing tree model (MPT), the two-high threshold model of recognition memory with three response categories (old, skip, and new). Using an MPT enabled us to adequately disentangle memory and response processes using the Fisher information approximation, a minimum description length based measure of model complexity. Results showed that participants exhibited an ORE on the memory parameters but not on the parameters representing response processes.
